Answer:

The price of a medium pizza with 3 toppings is $15.

Step-by-step explanation:

If "t" represents the number of toppings, you will use the expression "9+2t" and plug in 3 for t (since there are 3 toppings)

So it will look like:

9+2(3)

Then you're gonna use PEMDAS, multiply 2*3

9+6

And then you get an answer of $15

Answer:

  4%

Step-by-step explanation:

The interest earned on the investment is the difference between the end-of-year value and the initial value:

  $83.20 -80 = $3.20 . . . . simple interest per year

__

The interest rate is the ratio of this to the initial investment:

  $3.20/$80.00 = 0.04 = 4% . . . . . simple interest rate per year

Richard

Step-by-step explanation:

28 days=4 weeks

40 paintings in 4 weeks

45 paintings in 5 weeks

Richard weekly rate: 40/4=10 paintings per week

Nestor weekly rate: 45/5=9 paintings per week

If richard's rate is 10 while nestor's is 9, richard has a faster rate

Answer:

h=6

Step-by-step explanation:

To find the volume of a right angle prism-

Find area of cross-section, in this case an isoscles triangle so we know that both of the parallel lines are 3ft

To find the area of the cross-section, do:

3 x 3 = 9

9 ÷ 2 = 4.5 (Area of cross-section)

Since we don't know the length of h, we need do:

27^3 ÷ 4.5 = 6

Therefore 6 is h

Answer:

3468 students

Step-by-step explanation:

289 x 12 = 3468

Answer:

The Answer is C.

Step-by-step explanation:

f(x) = cos x , g(x) = cos(x - π/4)

Equation: f(x) = a * cos (x - h) + k

Since the equation only has h = π/4, it means that it shift right.

Answer:

31.5 in²

Step-by-step explanation:

The area of a triangle is calculated with the following formula:

1/2*b*h (b: base, h: height)

The height of this triangle is given as 9 and base is 7

1/2*7*9 = 31.5 in²

Answer:

31.5 in²

Step-by-step explanation:

Answer:

75

Step-by-step explanation:

because the formula of finding the area of a triangle is base times height divided by 2 so thatshow you get the answer, multiply 10by15 and then divide by 2

Answer:

(a) r = -0.947928522

(b) strong, negative

Step-by-step explanation:

The Product Moment Correlation Coefficient (r) measures the strength of the linear correlation between two variables.

The PMCC is always between +1 and -1.

The closer the value of r is to +1 or -1, the stronger the correlation between the two variables.

Inputting the data from the table into a calculator and using the statistical function:

r = -0.947928522

As the value of r is close to -1, the best description for the correlation would be strong, negative

Answer:

-2 square root 5

Step-by-step explanation:

Answer:

a: 88.5

b: 91

c: 91, 93

d: 88.5 AKA: the mean value.

Step-by-step explanation:

For answer D: A mean is defined as the mathematical average of the set of two or more data values which makes is perfect for calculating an overall grade by averaging all unit points together.

Answers:

=======================================================

Explanation:

Part (a)

To get the mean, first we add up the scores

89+91+94+93+93+67+90+91 = 708

Then we divide over 8 since there are 8 scores total

708/8 = 88.5

The mean is 88.5

-----------------

Part (b)

To get the median, we first need to sort the values from smallest to largest.

That sorted set looks like: {67,89,90,91,91,93,93,94}

Now cross off the first and last values to get this smaller subset: {89,90,91,91,93,93}

Repeat the last set of steps to cross off the first and last items to get {90,91,91,93}

Do this one more time to get {91,91}. The midpoint of these two values is 91, so it's the median of the entire original set.

The median is 91.

-----------------

Part (c)

The mode is {91, 93}

In other words, we have two modes and they are 91 and 93. It's perfectly possible to have more than one mode. The mode is the most frequent item(s). In this case, both 91 and 93 show up exactly twice which is the most of any other value.

As you can see, the mode isn't particularly useful as a single measure of center since we have two values instead of 1.

-----------------

Part (d)

As mentioned in the previous section, the mode isn't useful in this case. So we can rule it out. We can also rule out the mean because the value 67 is far from the group of other values (which is basically like the main cluster). We consider 67 an outlier.

The outlier pulls on the mean to be smaller than it should be. The median is a better measure of center since it's not affected by outliers.

As a real world example, consider home prices. The median price is used because of very expensive multimillion dollar mansions that greatly skew the mean to be larger than it should be.
