[tex]\huge\boxed{\bf\:1}[/tex]
Step-by-step explanation:
[tex]\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 } \times \frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }[/tex]
Take [tex]\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 }[/tex] & factorise it at first.
[tex]\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 } \\= \frac{\left(x-3\right)\left(x-1\right)}{\left(x-4\right)\left(x-3\right)}\\= \frac{x-1}{x-4}[/tex]
Now factorise the next set : [tex]\frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }[/tex].
[tex]\frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }\\= \frac{\left(x-4\right)\left(x+6\right)}{\left(x-1\right)\left(x+6\right)}\\= \frac{x-4}{x-1}[/tex]
Now, multiply the two simplified results.
[tex]\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 } \times \frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }\\= \frac{x-1}{x-4}\times \frac{x-4}{x-1} \\= \frac{\left(x-1\right)\left(x-4\right)}{\left(x-4\right)\left(x-1\right)} \\= \boxed{\bf\: 1}[/tex]

Find all possible values of x. The triangles are NOT drawn to scale.
Answers
Answer:
0 < x < 28
Step-by-step explanation:
The triangle inequality theorem states that the sum of any two sides of the triangle should be greater than the third side.
Therefore,
0 < x < 28All the possible values of x are 26 < x < 28.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
So a triangle has three sides.
We have the triangle inequality theorem which states that,
The length of any side of the triangle is always less than the sum of the other two sides.
And the range of the possible measure of the third side is the sum and the difference of the other two sides.
So x < 27 + 1 = 28
and,
x > 27 - 1 = 26
So 26 < x < 28
Hence the measures of third side is 26 < x < 28.

Step-by-step explanation:
A car rental company charges $28 per day for a rented car and $0.50 for every mile driven. A second car rental
company charges $20 per day and $0.75 for every mile driven. What is the number of miles at which both
companies charge the same amount for a one-day rental?
Answers
Answer:
56 miles
Step-by-step explanation:
According to the question, lets say the miles at x they charge the same rental
34 + 0.50x = 20 + 0.75x (Solve equation)
0.75x - 0.50x = 34 - 20
0.25x = 14
x = [tex]\frac{14}{0.25}[/tex]
x = 56
So at 56 miles, they charge the same rental.

The perimeter of a rectangle is 24. write the function that describes its area in terms of one of the sides. if one side is a, the formula will be S= ____
Answers
The area of the rectangle whose perimeter is 24 units and one side is of 'a' units, in terms of 'a' is given as: S = a(12-a) unit²
How to find the area of a rectangle?Suppose that the two adjacent sides of a rectangle be of 'a' units and 'b' unit lengths.
Then, we get the area of that rectangle as:
[tex]S = a \times b \: \rm unit^2[/tex]
For this case, we're specfied that:
One of the side of the considered rectangle is of 'a' units length.The perimeter of the considered rectangle = 24 unitsLet the other side (adjacent) be of 'b' units length
Then, as perimeter of a rectangle = 2(sum of lengths of one pair of adjacent sides of the rectangle)
Therefore, we get:
[tex]24 = 2(a+b)\\\text{Dividing both the sides by 2}\\12 = a + b\\b = 12 - a[/tex]
We expressed 'b' in terms of 'a' so that we can represent the area of the considered rectangle in terms of 'a' alone.
The area of the rectangle is:
[tex]S =a \times b = a \times (12 - a) \: \rm unit^2[/tex]
Thus, the area of the rectangle whose perimeter is 24 units and one side is of 'a' units, in terms of 'a' is given as: S = a(12-a) unit²

For a standard normal distribution, find the approximate value of p (negative 0.78 less-than-or-equal-to z less-than-or-equal-to 1.16). use the portion of the standard normal table below to help answer the question.
Answers
The approximate value of P(-0.78 ≤ Z ≤ 1.16) is obtained being 0.6593
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have [tex]X \sim N(\mu, \sigma)[/tex]
(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex])
then it can be converted to standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
[tex]P(Z \leq z) = P(Z < z) )[/tex]
Also, know that if we look for Z = z in z-tables, the p-value we get is
[tex]P(Z \leq z) = \rm p \: value[/tex]
For this case, we have to find:
[tex]P(-0.78\leq Z \leq 1.16)[/tex]
It can be rewritten as:
[tex]P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z < -0.78) \\P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z \leq -0.78)[/tex]
The p-values for Z = 1.16 and Z = -0.78 from the z-table is found as 0.8770 and 0.2177 respectively, and therefore, we get:
[tex]P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z \leq -0.78)\\P(-0.78\leq Z \leq 1.16) = 0.8770 - 0.2177 = 0.6593[/tex]
Thus, the approximate value of P(-0.78 ≤ Z ≤ 1.16) is obtained being 0.6593

A couch is discounted by $299. If the original price is $1250 , estimate the sale by price by first rounding each number to the nearest hundred
Answers
Answer: $950
1250-299=951
round off to nearest hundred, $950
The estimated sale price of the couch after rounding each number to the nearest hundred is $901.
To estimate the sale price of the couch, we first need to round each number to the nearest hundred.
Original price: $1250
Rounded to the nearest hundred: $1200
Discount amount: $299
Now, let's calculate the estimated sale price by subtracting the discount from the rounded original price:
Estimated Sale Price = Rounded Original Price - Discount Amount
Estimated Sale Price = $1200 - $299
Estimated Sale Price = $901
The estimated sale price of the couch after rounding each number to the nearest hundred is $901.

a)Finding the slope of the line is made easier by an appropriate choice of a pair of table values:

m = (24 -20.20)/(5 -4) = 3.80/1 = 3.80 . . . . using (4, 20.20) and (5, 24)
The y-intercept can likewise be found with an appropriate choice of table values. Solving the slope-intercept equation for b, we get ...
y = mx +b
b = y -mx
b = 8.80 -3.80 × 1 = 5.00 . . . . using the first table value
