Answer:

27

Step-by-step explanation:

9.00 divided by 4 = 2.25

2.25 x 12 = 27

Answer:

$27

Step-by-step explanation:

First, you would take 12(amount of pizzas the question is asking) divided by 4(amount of pizzas) and get 3

Then you multiply $9.00(the delivery fee for 4 pizzas) by 3(how much pizzas the question is asking divided by 4) and get $27

12 divided by 4 = 3

3 times $9.00 = $27

= 80/100 x 200 = 160

So 160 students

Note: The only way to solve this problem is by adjusting the fees to $3.50 and $7.50.

Answer:

1300 children attended the basketball game

Step-by-step explanation:

System of Equations

Let's call:

x = number of children attending the basketball game

y = number of adults attending the basketball game

On a certain night, 1500 people enter the game, thus:

x + y = 1500           [1]

Since each admission fee for children cost $3.50 and $7.50 for adults and it was collected $6050, thus:

3.50x + 7.50y = 6050            [2]

From [1]:

y = 1500 - x

Substituting in [2]:

3.50x + 7.50(1500 - x) = 6050

Operating:

3.50x +  11250 - 7.50 = 6050

-4x = 6050 - 11250

Solving:

x = 1300

1300 children attended the basketball game

Answer:

f(-8) = 54

Step-by-step explanation:

To start, replace x in the equation with -8. This will give you f(-8) = 6(1 - (-8)) which can be simplified to f(-8) = 6(1 + 8). Apply the distributive property on the right side of the equation to get f(-8) = 6 + 48. When simplified, you get f(-8) = 54.

X=2x +£2x -15) +2x +(2x +24) 180= 9x+7x = 9 +9x = 18

3) We know that the x intercept is the value of x when y is 0. We also know that the Y intercept is the value of y when x is 0. Both maximums can represent either a y or x intercept because they are the value when you don't have any money left or $0.

Step-by-step explanation:

1) 15 ÷ 0.25= 60

Step-by-step explanation:

4 by 7 is equivalent because 4 times 2 is 8 and 7 times 2 is 14

Answer:

Yes, the ratios are equivalent

Step-by-step explanation:

The x-intercepts are x = 2/3 and x = 3.

The y-intercept is (0, 6).

A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.

The equation of a parabola:

y = a(x - h)² + k

we have,

To find the x-intercepts, we set y to zero and solve for x:

0 = −3x^2 − 5x + 6

We can factor this quadratic equation:

0 = (−3x + 2)(x − 3)

x - 3 = 0

x = 3

And,

-3x + 2 = 0

-3x = -2

x = 2/3

So the x-intercepts are x = 2/3 and x = 3.

To find the y-intercept, we set x to zero and evaluate y:

y = −3(0)² − 5(0) + 6

y = 6

So the y-intercept is (0, 6).

Thus,

The x-intercepts are x = 2/3 and x = 3.

The y-intercept is (0, 6).

Answer:

7 ten dollar bills and 5 twenty dollar bills

Step-by-step explanation

He recieved 5 bills of $20 and 7 bills of $10.

We have the following statement Angelo cashed a check for $170, the bank teller gave him 12 bills, some $20 bills and the rest $10 bills

We can write -

20x + 10y = 170

x + y = 12

So, we can write -

y = 12 - x

We can write -

20x + 10(12 - x) = 170

20x + 120 - 10x = 170

10x = 50

x = 5

then -

y = 7

Therefore, he recieved 5 bills of $20 and 7 bills of $10.

Answer:

This known value does not match the measured value at the 95% confidence level.

The 95% confidence interval for value is calculated as 42.92 to 43.78%,

Step-by-step explanation:

The complete question is:

Police have a hit-and-run case and need to identify the brand of red auto paint. The percentage of iron oxide, which gives paint its red color, was determined to be 43.35 ± 0.33% by one method of analysis using five measurements. The color reference provide by the automotive manufacture is 44.21%. What can you conclude about whether the sample matches the reference at a 95% confidence level?

Student's t test is used to compare the two values .

Here n=5

Degrees of freedom =ν= n-1= 5-1=4

The value from t- table for 4 d.f at 95 % confidence interval is 2.776

The test statistic is

x`± t ∝/2(v). S/√n

43.35 ± (2.776)(0.33)/√5

= 43.35 ± 0.43

= 43.78, 42.92

Here the 95% confidence interval for μ calculated is 42.92 to 43.78%, where as color reference provided by the automotive manufacture is 44.21%.

This known value does not match the measured value at the 95% confidence level.

Answer:

Based on the number of cookies each girl made and if Kristina and Liz made the same number of cookies, then Heather made 4.2 dozen cookies.

Step-by-step explanation:

In order to find the number of cookies that Heather made, you need to set up two equations that represent the number of cookies that Kristina and Liz each made.  Since Kristina made 2.4 dozen less than 6 times as many dozen as Heather, we can represent that with the equation  6c - 2.4.  Since Liz made 1.8 dozen more than 5 times as many dozen as Heather, we can represent that with the equation 5c + 1.8.  We can set both equations equal to each other since Liz and Kristina made the same number, so 6c - 2.4 = 5c + 1.8.  Solving for 'c', which represents how many dozen cookies Heather made, we get 4.2
