The best estimate of the true value for this data set is the mean value, which is 1000 rpm.
To calculate the mean value, we add up all the values and divide by the
number of values:
(990 + 1030 + 950 + 1050 + 1000 + 980) / 6 = 1000
So the mean value is 1000 rpm.
To calculate the standard deviation, we need to first calculate the
variance:
Variance =[tex][(990 - 1000)^2 + (1030 - 1000)^2 + (950 - 1000)^2 + (1050 - 1000)^2 + (1000 - 1000)^2 + (980 - 1000)^2] / 6[/tex]
Variance = 12000 / 6 = 2000
So the variance is [tex]2000 (rpm)^2[/tex].
The standard deviation is the square root of the variance:
Standard deviation = √(2000) = 44.7 rpm
The best estimate of the true value for this data set is the mean value, which is 1000 rpm.

what is the probability that betty is first in line or mary is last in line as a function of n? simplify your final expression as much as possible and include an explanation of how you calculated this probability.
The probability that Betty is first in line or Mary is last in line is (n^2 - n - 1)/n(n-1), as a function of n.
We can approach this problem by considering the probability of the complementary event, i.e., the probability that neither Betty is first in line nor Mary is last in line, and then subtracting this probability from 1 to get the probability we want.
The total number of ways the n kids can line up is n!, since there are n choices for the first person in line, n-1 choices for the second person, and so on down to 1 choice for the last person.
The number of ways in which neither Betty is first in line nor Mary is last in line is (n-2)!, since there are (n-2) choices for the first person in line (excluding Betty and Mary), (n-3) choices for the second person, and so on down to 1 choice for the second-to-last person.
Therefore, the probability that neither Betty is first in line nor Mary is last in line is
[(n-2)! / n!] = 1/n(n-1)
The probability we want is
1 - 1/n(n-1) = (n^2 - n - 1)/n(n-1)

an artist needs to enlarge a statue by making each linear dimension 75% greater. if n cm3 of clay was used to make the original sculpture, how many cubic centimeters of clay are needed to make the larger sculpture?
To make the larger sculpture with each linear dimension 75% greater, the artist needs to use 265.625% or 3.65625 times more clay than the original sculpture.
Let's assume that the original sculpture is a cube with side length x cm. Therefore, its volume would be x³ cm³.
To make the larger sculpture, each linear dimension needs to be increased by 75%, which means that each side length will become 1.75x cm. Thus, the new volume of the sculpture will be (1.75x)³ = 5.378125 x³ cm³.
To find the amount of clay required to make the larger sculpture, we need to find the ratio of the new volume to the original volume (5.378125 x³ cm³) / (x³ cm³) = 5.378125
This means that the artist needs to use 5.378125 times more clay than the original amount used to make the larger sculpture.
Therefore, to find the actual amount of clay needed, we multiply the original amount of clay by 5.378125: n cm³ x 5.378125 = 5.378125n cm³
So, the artist needs to use 3.65625 or 265.625% times more clay than the original sculpture to make the larger sculpture with each linear dimension 75% greater.

PLS Give answer for 7. 8. 9.
Answer:
7. shifted right 8 units
8. shifted left 4 and up 12 units
9. shifted up 8 units
Step-by-step explanation:
You want to compare the given functions with p(x) = a(x -h)² +k and tell the value and effect of a, h, and k on the vertex.
TransformationsIn the equation for p(x) above, the value 'a' represents a vertical scale factor. It expands the graph vertically by the factor 'a'. If a < 0, the graph is reflected across the x-axis.
The values 'h' and 'k' in the equation for p(x) represent a right shift of the graph by 'h' units and a shift up by 'k' units. That is, the graph is translated by (h, k).
7. g(x)We have h = 8. The graph is shifted right 8 units.
8. h(x)We have (h, k) = (-4, 12). The graph is shifted left 4 units and up 12 units.
9. f(x)The values of the transformation parameters are a = -1/2 and k = 8. The vertical compression and reflection do not affect the vertex. The vertex is shifted up 8 units.

The vertices of the ellipse are (-4,2) and (4,2), since these points lie on the major axis of the ellipse which is horizontal.
Two of the focuses given in the issue, (−4,2) and (4,2), are both situated on a similar even line. This implies that the significant hub of the oval should be level. Two different focuses given in the issue, (2,2) and (- 9,2), are likewise situated on this level line. Thusly, the focal point of the oval is the midpoint between the focuses (- 4,2) and (4,2), which is (0,2).
The other two focuses given in the issue, (−5,5) and (−5,−1), are situated on an upward line that goes through the focal point of the oval. This implies that the minor pivot of the oval should be vertical.
The vertices of the oval are the places where the significant hub meets the circle. Since the significant hub goes through the focuses (−4,2) and (4,2), the vertices of the oval are (- 4,2) and (4,2).

An isosceles trapezoid has a perimeter of 45 millimeters. Its shorter base measures 6.3 millimeters and its longer base measures 16.1 millimeters. The two remaining sides have the same length; what is that length?
The length of the two equal sides of the isosceles trapezoid is 11.3 millimeters.
What is trapezoid?
A trapezoid, also known as a trapezium in some countries, is a two-dimensional geometric shape with four sides. It is a quadrilateral that has at least one pair of parallel sides, which are called bases.
Let's start by labeling the sides of the isosceles trapezoid as follows:
The shorter base: b1 = 6.3 mm
The longer base: b2 = 16.1 mm
The two equal sides: s
We know that the perimeter P of the trapezoid is given by:
P = b1 + b2 + 2s
Substituting the values we have, we get:
45 mm = 6.3 mm + 16.1 mm + 2s
Simplifying this equation, we get:
22.6 mm = 2s
Dividing both sides by 2, we get:
s = 11.3 mm
Therefore, the length of the two equal sides of the isosceles trapezoid is 11.3 millimeters.

a basket contains 14 apples, of which two are rotten. a sample of three apples is selected at random. what is the probability that the sample contains two rotten apples?
The probability that the sample contains two rotten apples is 0.0612.
The sample of three apples can be selected in 14C3 (14 choose 3) ways and the probability that we select a rotten apple will be 2/14 and the probability of selecting an apple that is not rotten is 12/14.
Now we can apply the binomial distribution formula, to calculate the probability as follows,
P = (3 choose 2) × (2/14)² × (12/14)
P = (3! / (2! × 1!)) × (2/14)² × (12/14)
P = 3 × (1/49) × (12/14)

As a result, 2x + 10 is the expression that describes how long Malik will cook the sirloin for if the asparagus grills for x minutes.
What is a good expression of the phrase?So, 1+1 is a straightforward illustration of a statement. This expression has one action, two constant elements, and (addition). Another illustration is x3.
Let's start by using the given information to create expressions for each item:
Let's call the time it takes to grill the fish "f". Then, according to the problem, Malik grills the steak for "f + 10" minutes.
Grilling time for the seafood is double that of the vegetables. Thus, if it requires "x" minutes to grill asparagus, "2X" minutes are needed to grill salmon.
For "x + 1" minutes, and this is one minute more than he roasts the asparagus, Malik cooks the tomatoes that have been cut in half.
Using these expressions, we can create an equation for the time it takes to grill the steak:
Time to grill steak = Time to grill fish + 10

(co 1) in a normally distributed data set of how long customers stay in your store, the mean is 44.8 minutes and the standard deviation is 2.6 minutes. within what range would you expect 95% of your customers to stay in your store? g
You can expect 95% of your customers to stay in your store between range of 39.7 minutes and 49.9 minutes.
To determine the range in which 95% of your customers would stay in your store, we will use the properties of a normally distributed data set with a mean of 44.8 minutes and a standard deviation of 2.6 minutes.
Identify the mean and standard deviation.
The mean is 44.8 minutes, and the standard deviation is 2.6 minutes.
Determine the z-score for a 95% confidence interval.
A 95% confidence interval corresponds to a z-score of 1.96. This means that 95% of the data lies within 1.96 standard deviations from the mean.
Calculate the range using the z-score, mean, and standard deviation.
To find the lower and upper limits of the range, we will multiply the standard deviation (2.6 minutes) by the z-score (1.96) and then subtract or add the result to the mean (44.8 minutes).
Lower limit: Mean - (Z-score × Standard deviation)
44.8 - (1.96 × 2.6) = 44.8 - 5.096 ≈ 39.7 minutes
Upper limit: Mean + (Z-score × Standard deviation)
44.8 + (1.96 × 2.6) = 44.8 + 5.096 ≈ 49.9 minutes

The parabola's equation is therefore for A: y = 7x2 - 5$1.
As a result, the parabola's equation for B is y = -1/2(x - 1)² + 4.
A parabola with vertex (h,k) has the basic equation y = a(x-h)² + k². In this instance, h=0 and k=-5 are equal because the vertex is at $(0,-5)$. Moreover, the parabola has a point at (-1 . 2). When we substitute these numbers in the general parabola equation, we obtain:

What is a parabola?A cone and a plane perpendicular to its side cross to create a symmetrical open plane curve known as a parabola1. It is a U-shaped curve whose vertex and axis of symmetry characterise it. The line dividing the parabola into its two mirror counterparts is known as the axis of symmetry. The parabola's vertex is where the axis of symmetry intersects it.
A parabola's vertex is represented by the equation y = a(x - h)²+ k, where (h,k) represents the vertex. We may utilise the vertex version of the equation and substitute the values of h, k, and the x and y coordinates of the point to determine the equation of a parabola that passes through a particular point and has a certain vertex.
B. Here, the vertex is (1, 4), and the point (5,-4). In the vertex form equation, we may therefore substitute h=1, k=4, x=5, and y=-4 to obtain:
-4 = a(5 - 1)²2 + 4 \s-8 = 16a
a = -1/2
As a result, the parabola's equation is y = -1/2(x - 1)² + 4.

10. A bag contains 3 red marbles, 7 white marbles, and 5 blue marbles. You draw 3 marbles, replacing each one before drawing the next. What is the probability of drawing a red, then a blue, and then a white marble?
the probability of drawing a red, then a blue, and then a white marble is [tex]=\frac{7}{225}[/tex]
To find probability, we take the number of ways the specific event can occur and divide it by the number of ways any event can occur.
The probability of drawing a red marble is: (of red marbles) / (total # of marbles) = 3/(3 + 7 + 5) = 3÷15 = 1÷5.
The probability of drawing a blue marble is: ( of blue marbles) / (total # of marbles) = 5/(3 + 7 + 5) = 5÷15 = 1÷3.
The probability of drawing a white marble is: ( of white marbles) / (total # of marbles) = 7/(3 + 7 + 5) = 7÷15.
Now, we want these events to all to occur for us. So, we must multiply them by each other: (1/5) * (1/3) * (7/15) [tex]=\frac{7}{225}[/tex]
Thus, the probability is [tex]=\frac{7}{225}[/tex]

Mia is buying a computer monitor that is 18
inches tall and has a distance of 30 inches
between opposite corners. What is the width of
Mia's new monitor?
inches
This problem is a Pythagorean theorem word problem
Answer:
To solve this problem, we can use the Pythagorean theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.In this case, the height of the monitor is one leg of the right triangle, and the width of the monitor is the other leg. The distance between opposite corners is the hypotenuse.Let w be the width of the monitor in inches. Then we have:w^2 + 18^2 = 30^2Simplifying and solving for w, we get:w^2 + 324 = 900
w^2 = 576
w = 24Therefore, the width of Mia's new monitor is 24 inches.
Step-by-step explanation:
in a class, 2/5 of the students play basketball, and 7/10 play soccer. of the students who play basketball, 2/3 also play soccer. there are 30 students in the class. how many students play soccer but do not play basketball?
If there are 30 students in the class, then the number of students who play soccer but do not play basket-ball are 13 students.
The total-students in the class is = 30 students,
The Number of students who play basketball is = (2/5) × 30 = 12,
The Number of students who play soccer is = (7/10) × 30 = 21,
⇒ Number of basketball players who also play soccer = (2/3) × 12 = 8,
So, out of the 21 students who play soccer, 8 also play basketball.
To find the number of students who play soccer but not basketball, we can subtract the number of students who play both from the total number of soccer players:
⇒ 21 - 8 = 13 students play soccer but not basketball.
Therefore, the required number of students are 13 students.

The jacobs family is planning to buy a home they have some money for. Down payment already they see a home they like and compute that they would need to borrow 213,000 from a bank over a 30-year period the apr is 3.75%
3 part question
A. What is the monthly payment to the nearest 10th
b. What is total if all of the monthly payments over the 30 years
C. What is her total interest for the 30 years
Step-by-step explanation:
A. To calculate the monthly payment, we can use the formula for a fixed-rate mortgage:
M = P * (r*(1+r)^n) / ((1+r)^n - 1)
where:
M = monthly payment
P = principal (amount borrowed) = $213,000
r = monthly interest rate = APR / 12 = 0.0375 / 12 = 0.003125
n = total number of payments = 30 years * 12 months/year = 360
Plugging in these values, we get:
M = 213000 * (0.003125*(1+0.003125)^360) / ((1+0.003125)^360 - 1)
M ≈ $988.32
So the monthly payment, rounded to the nearest 10th, is $988.30.
B. The total amount paid over the 30-year period would be the monthly payment multiplied by the total number of payments:
Total = M * n
Total = $988.30 * 360
Total = $355,788.00
So the total amount paid over 30 years would be $355,788.00.
C. To calculate the total interest paid over the 30-year period, we can subtract the principal from the total amount paid:
Total Interest = Total - P
Total Interest = $355,788.00 - $213,000
Total Interest = $142,788.00
So the total interest paid over the 30-year period would be $142,788.00.
