Answer:
X = 2² * 3² * 5³ * 7.
Step-by-step explanation:
140 = 2*2*5*7
15^2 = 3*5*3*5
So X = 2² * 3² * 5³ * 7
To find the prime factorization of X, we first need to simplify the expression.
140 × 15² = 140 × 225Now, we can factor 140 and 225 into their prime factors:
140 = 2² × 5 × 7225 = 3² × 5²So,
X = 140 × 225= (2² × 5 × 7) × (3² × 5²)We can now use the distributive property to multiply these factors together:
X = 2² × 3² × 5³ × 7Therefore, the prime factorization of X is:
Therefore, the prime factorization of X is:X = 2² × 3² × 5³ × 7Find the length of side a given a = 50°, b = 20, and c = 35. round to the nearest whole number.
The length of side a is 50 if the angle ∠bac is 50° and the length of side b is 20 and side c is 35 using cosine law.
Length of side b = 20
Length of side c = 35
Angle ∠bac = 50°
To calculate the length of the side a, we need to use the cosine law. The formula is:
[tex]a^2 = b^2 + c^2 - 2bc cos(A)[/tex]
Substituting the given values in the formula, we get:
[tex]a^2 = 20^2 + 35^2 - 2(20)(35)cos(50°)[/tex]
[tex]a^{2}[/tex] = 400 + 1225 + (1400)*(0.642)
[tex]a^{2}[/tex] = 1625 + 898.8
a = [tex]\sqrt{2523.8}[/tex]
a = 50
Therefore we can conclude that the length of side a is 50 using cosine law.

The final exam scores in a statistics class were normally distributed with a mean of
63 and a standard deviation of five.
find the score that marks the 11% of all scores.
The score that marks the 11% of all scores is approximately 56.875 .
To find the score that marks the 11% of all scores, we need to use the standard normal distribution table, also known as the Z-table, since the given distribution is a normal distribution.
The first step is to find the Z-score that corresponds to the 11th percentile, which is given by: Z = invNorm(0.11) ≈ -1.225
Here, "invNorm" represents the inverse of the standard normal cumulative distribution function, which can be computed using statistical software or a calculator.
The second step is to use the Z-score formula to find the raw score that corresponds to this Z-score:Z = (X - μ) / σ
where X is the raw score we want to find, μ is the mean of the distribution, and σ is the standard deviation. Plugging in the values we have:
-1.225 = (X - 63) / 5
Solving for X, we get:
X = -1.225 * 5 + 63 = 56.875
Therefore, the score that marks the 11% of all scores is approximately 56.875

The graph shows f(x). The absolute value function g(x) is described in the table. The graph shows a v-shaped graph, labeled f of x, with a vertex at 0 comma 2, a point at negative 1 comma 3, and a point at 1 comma 3. x g(x) −1 5 0 4 1 3 2 2 3 3 If g(x) = f(x + k), what is the value of k? k = −2 k is equal to negative one half k is equal to one half k = 2
Where the above graph and conditions are given, the value of k that satisfies g(x) = f(x+k) is k = -2.
What is the explanation for the above response?We can determine the value of k by using the given relationship between g(x) and f(x+k).
If g(x) = f(x + k), then we can substitute the given values of x in g(x) to get:
g(-1) = f(-1 + k) --> 5 = f(-1 + k)
g(0) = f(0 + k) --> 4 = f(k)
g(1) = f(1 + k) --> 3 = f(1 + k)
g(2) = f(2 + k) --> 2 = f(2 + k)
g(3) = f(3 + k) --> 3 = f(3 + k)
We know that f(x) is a v-shaped graph with a vertex at (0,2) and points at (-1,3) and (1,3). Therefore, we can conclude that f(k) = 4, which means that k is the x-coordinate of the vertex of f(x) shifted to the left or right.
Since the vertex of f(x) is at (0,2), and the x-coordinate of the vertex of f(x+k) is at k, we have:
k = 0 --> vertex of f(x+k) is at (0,2)
k = -1 --> vertex of f(x+k) is at (-1,2)
k = 1 --> vertex of f(x+k) is at (1,2)
k = 2 --> vertex of f(x+k) is at (2,2)
Therefore, the value of k that satisfies g(x) = f(x+k) is k = -2.

Drake was trying to write an equation to help him predict the cost of his monthly phone bill.
He is charged $35 just for having a phone, and his only additional expense comes from the number of text that he sends,
He is charged $0. 05 for each text. Name the function C(t), where C(t) is the cost of bill according to number of text.
The function for Drake's monthly phone bill, C(t), is C(t) = 35 + 0.05t, where t represents the number of texts sent.
Drake has two components to his monthly phone bill: the base cost of $35 and the additional cost for texts sent. The base cost is fixed, meaning it does not change, so we can represent it as a constant value in the function (35).
The cost per text is $0.05, which means it varies depending on the number of texts sent (t). To find the total cost (C(t)), we need to add the fixed cost ($35) and the variable cost ($0.05 times the number of texts). Therefore, the function representing Drake's monthly phone bill cost is C(t) = 35 + 0.05t.

The estimated probability that it will take at least five patients to find one patient on whom the medicine would not be effective is [blank]. The estimated probability that the medicine will be effective on exactly three out of four randomly selected patients is [blank]
a. The ratio of Es to Ns in percentage is 64%
b. Probability that it will take at least five patients to find one patient on whom the medicine would not be effective is impossible to estimate this probability from the table.
c. The probability that the medicine will be effective on exactly three out of four randomly selected patients is 12.9%
a. The total number of patients in the table is 50.
To calculate the ratio of Es to Ns in percentage, we count the number of Es and Ns and divide the number of Es by the number of Ns and Es combined, and then multiply by 100. Counting the table, we find that there are 32 Es and 18 Ns. So, the ratio of Es to Ns in percentage is:
32 / (32 + 18) * 100 = 64%
b. To estimate the probability that it will take at least five patients to find one patient on whom the medicine would not be effective, we need to look at the runs of Ns in the table. We can see that there are no runs of five or more Ns, so it is impossible to estimate this probability from the table.
c. To estimate the probability that the medicine will be effective on exactly three out of four randomly selected patients, we need to count the number of ways we can choose three Es and one N, and divide by the total number of possible outcomes of selecting four patients from the table. The total number of possible outcomes is:
50 choose 4 = 50! / (4! * (50-4)!) = 230300
The number of ways we can choose three Es and one N is:
32 choose 3 * 18 choose 1 = (32! / (3! * (32-3)!)) * (18! / (1! * (18-1)!)) = 32 * 31 * 30 / (3 * 2) * 18 = 32 * 31 * 30 * 18 / 6 = 297120
So, the estimated probability that the medicine will be effective on exactly three out of four randomly selected patients is:

tony collected data on the years of employment and the annual salaries of the salespeople at company z. he made a scatterplot and drew a trend line that approximates the line of best fit for the data, as shown below.Tony expects his salary to be about $70,000 after he has been employed as a sales person at company z for 15 years. use the trend line and slope to explain whether tony's salary expectation is reasonable.
Based on the trend line and slope, Tony's expected salary of $70,000 after 15 years of employment at Company Z is reasonable, as it falls within the range of salaries predicted by the line of best fit.
First, we need to find the equation of the trend line. To do this, we use the least squares regression method to find the line that best fits the data. Let x be the years of employment and y be the annual salary. We can calculate the slope and y-intercept of the trend line using the following formulas
slope = (nΣ(xy) - ΣxΣy) / (nΣ(x²) - (Σx)²)
y-intercept = (Σy - slopeΣx) / n
where n is the number of data points, Σ represents the sum of, and ( )² denotes squared.
We can use the given data to calculate the values needed for the formulas. Let's denote the years of employment as x and the annual salary as y.
x: 1 2 3 4 5 6
y: 45 50 55 60 65 70
n = 6
Σx = 1 + 2 + 3 + 4 + 5 + 6 = 21
Σy = 45 + 50 + 55 + 60 + 65 + 70 = 345
Σxy = (145) + (250) + (355) + (460) + (565) + (670) = 1305
Σ(x²) = 1² + 2² + 3² + 4² + 5² + 6² = 91
Now we can plug these values into the formulas to find the slope and y-intercept
slope = (61305 - 21345) / (691 - 21²) = 5
y-intercept = (345 - 521) / 6 = 20
We can write the equation of the trend line in the form y = mx + b, where m is the slope and b is the y-intercept
y = 5x + 20
Finally, we can use this equation to estimate Tony's salary after 15 years of employment
y = 5(15) + 20 = 95
Based on the trend line and slope, we would expect Tony's salary to be about $95,000 after 15 years of employment.
This is higher than his expected salary of $70,000, so it may not be a reasonable expectation. However, it's important to note that the trend line is just an approximation and there may be other factors that could affect Tony's salary.

The roof of a building is in the shape of a hyperbola, y^2-x^2=38, where x and y are in meters. Determine the height of the outside. The distance between the center of the hyperbola and the walls is 3m.
a) -29. 1
b) 47. 3
c) 35. 2
d) 6. 9
The height of the outside is given as 17.44 meters
How to solveThe equation of hyperbola is :
[tex]y^2 - x^2 = 38[/tex]
=>[tex]y^2/38 - x^2/38 = 1[/tex]
(of the form [tex]y^2/a^2 - x^2/b^2 = 1[/tex] and transverse axis is y-axis.)
Here, [tex]a^2 = b^2 = 38[/tex]
[tex]c^2 = a^2 + b^2 = 38+38 = 76[/tex]
( a is the distance of vertices from the center and c is the distance of foci from the center.)
Distance between walls = 2 a = [tex]2*\sqrt(38) = 12.33[/tex] meters at the center
and = [tex]2c = 2*\sqrt(76) = 17.44[/tex] meters at the end when the line joining

The car model that is least likely to have a brake failure is model d, and the probability of brake failure for this model is 0.0029%.
The given table provides the probabilities of brake failure for different car models. We need to identify the car model that has the lowest probability of brake failure and the corresponding probability.
From the table, we can see that the probability of brake failure is the lowest for model d, which is 0.0029%. To find this, we simply need to compare the probabilities given in the table and identify the smallest one.
It's worth noting that the total probability of brake failure across all car models is 0.0048%, which means that the probability of brake failure for any individual car model is quite low.
To express this in a more tangible way, we could say that out of 1000 new cars of model d, we can expect only about 2 or 3 to have brake failure. The low probabilities of brake failure suggest that new cars in general are quite safe and reliable when it comes to braking performance.

Answer:
g(x) = h(x -7) +5
Step-by-step explanation:
Given h(x) defines a parabola that opens upward with a vertex at (-2, -7) and g(x) defines the same parabola with its vertex at (5, -2), you want to express g(x) in terms of h(x).
TranslationThe graph of f(x) is translated right h units and up k units by ...
f(x -h) +k
We see that g(x) is a translation of h(x) right by 7 units and up by 5 units. This means (h, k) is (7, 5), and the translated function is ...
g(x) = h(x -7) +5

Additional comment
This is confirmed by the plots in the second attachment.
Answer: g(x)=h(x-7) +5
Step-by-step explanation:
The graph g(x) has been shifted up 5 (+5) and right 7
When shift a function, the y change, up/down, goes at end of function
When shift in x direction happens, you take opposite sign so we will do -7

The domain of g(x) = log 56 - x) can be found by solving the inequality
A. 6-x<0 ,B. 6-x>0,C. 6-x>=0, D. 6-x<=0
The inequality to solve is 56 - x > 0. The solution is x < 56. Therefore, the domain of the function g(x) is x < 56. So, the answer is option B.
The function is defined as g(x) = log(56 - x).
The domain of a logarithmic function is all the values that make the argument of the logarithm positive. In other words, the argument of the logarithm (56 - x) must be greater than 0.
So, we solve the inequality 56 - x > 0 for x
56 - x > 0
Subtract 56 from both sides
-x > -56
Divide both sides by -1, and remember to reverse the inequality
x < 56
Therefore, the domain of the function g(x) is all real numbers x such that x < 56. So, the correct answer is B).

I have some coins in my pocket. Nickles and pennies I have a total of $. 41 I have 21 coins in total. How many Nickles and pennies do I have?
The number of nickels and pennies in the pocket is 5 and 16 respectively.
How to find the number of coins?To find the number of coins, Let's assume the number of nickels is x and the number of pennies is y.
According to the problem, we have two equations:
The total value of the coins is $0.41:
0.05x + 0.01y = 0.41
The total number of coins is 21:
x + y = 21
Now we can solve this system of equations to find x and y. One way to do this is to use substitution.
Solving the second equation for y, we get:
y = 21 - x
Substituting this into the first equation, we get:
0.05x + 0.01(21 - x) = 0.41
Simplifying:
0.05x + 0.21 - 0.01x = 0.41
0.04x = 0.2
x = 5
So we have 5 nickels.
Substituting this into the equation y = 21 - x, we get:
y = 21 - 5 = 16
So we have 16 pennies.
Therefore, the number of nickels and pennies in the pocket is 5 and 16 respectively.

If a couch measures 10ft across in real life, what would it's measurement be in the scale drawing (in)
Explain
the measurement of the couch in the scale drawing would be 15 inches.
what is scale drawing?We can precisely portray locations, areas, structures, and details in scale drawings at a scale that is either smaller or more feasible than the original.
When a drawing is said to be "to scale," it signifies that each piece is proportionate to the real or hypothetical entity; it may be smaller or larger by a specific amount.
When something is described as being "drawn to scale," we assume that it has been printed or drawn to a conventional scale that is accepted as the norm in the construction sector.
When our awareness of scale improves, we are better able to quickly recognize the spaces, zones, and proposed or existent spatial relationships when looking at a drawing at a given scale.
One metre is equivalent to one metre in the actual world. When an object is depicted at a 1:10 scale, it is 10 times smaller than it would be in real life.
You might also remark that 10 units in real life are equivalent to 1 unit in the illustration.
To determine the measurement of the couch in the scale drawing, we can use the scale factor provided:
1/4 inch = 2 feet
This means that every 1/4 inch in the drawing represents 2 feet in real life.
To find the measurement of the couch in the drawing, we need to convert its actual size to the corresponding size in the drawing using the scale factor.
First, we can convert the actual size of the couch to feet:
10 ft = 10 ft x 12 inches/ft = 120 inches
Next, we can use the scale factor to convert the actual size to the corresponding size in the drawing:
1/4 inch = 2 feet
1 inch = 8 feet (multiplying both sides by 4)
So, 120 inches in real life is equal to:
120 inches / 8 feet per inch = 15 inches in the drawing
Therefore, the measurement of the couch in the scale drawing would be 15 inches.
