Two pizza delivery drivers compared the mean numbers of
deliveries they completed in one day,
Mean number of deliveries Mean Absolute Deviation (MAD)
Driver A
10
2
Driver B 20
2
Which statement about the data is true?
A. On average, driver A delivers more pizzas in one day than driver B.
O B. The mean number of deliveries for driver A is less than the mean
for driver B by 2 MADS.
OC. The MAD for driver A is less than the MAD for driver B.
O D. The mean number of deliveries for driver A is less than the mean
for driver B by 5 MADs.
Answer:
D.
Step-by-step explanation:
The difference in pizza delivered between driver A and driver B is 10 pizzas.
We can find this by doing 20-10 which is 10.
The MAD is 2.
D says that Driver A has less pizzas delivered than Driver B by 5 MADs. Since 1 MAD is 2, 5 MADs is 10.
Meaning D says that driver A delivered 10 less pizzas than Driver B, which is correct.

What is the inverse of the function below?
Answer:
B
Step-by-step explanation:
Let y be the function f(x)
for inverse
x =y÷3-2
or, x + 2 = y ÷3
or, ( x + 2)3 =y
so inverse of f(x) is (x + 2) 3
Suppose a normal distribution has a mean of 48 and a standard deviation of 5. What is the probability that a data value is between 48 and 52? Round your answer to the nearest tenth of a percent. O A. 26.2% . B. 30.5% O c. 31.1% O D. 28.8%
Answer:
31.1 best answer
sorry if it's wrong
28.8% is the probability that a data value is between 48 and 52.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
First, we need to standardize the values and use a standard normal distribution table or calculator.
The standardized value of 48 is:
z = (48 - 48) / 5 = 0
The standardized value of 52 is:
z = (52 - 48) / 5 = 0.8
Now we need to find the probability that a data value is between z = 0 and z = 0.8 in a standard normal distribution. We can use a standard normal distribution table or calculator to find this probability.
Using the table or calculator, we can find that the probability of a data value being between z = 0 and z = 0.8 in a standard normal distribution is approximately 0.2881.
Rounding this answer to the nearest tenth of a percent, we get:
P(48 < x < 52) ≈ 28.8%
Therefore, the answer is D, 28.8%.

A pile of cards contains red and blue
cards. The ratio of blue cards to red
cards is 5:7, and there are 15 blue
cards in the pile. What is the total
number of cards in the pile?
Answer:
There are 36 cards
Step-by-step explanation:
let blue be B and red be R
B:R =5:7
B/R = 5/7
there are 15 blue cards...
15/R = 5/7
make R subject of the formula...
R = (15×7)/5
R = 21
there are 21 red cards and 15 blue cards
Total number of cards = red cards + blue cards
= 21 + 15
= 36 cards

I know the answer is no x intercepts because we have an answer sheet to check our answers i just forgot how to do this and would appreciate an explanation: ind the number of x-intercepts of y= -x^2 + 4x - 12
Answer:
negative square root will result in zero x-intercepts
Step-by-step explanation:
there are no x-intercepts because if you use the quadratic formula on the equation you get a negative square root which results in zero x-intercepts
in this case, a=-1, b=4, c=-12
[-4±√4² - 4(-1)(-12)] / 2(-1)
= [-4 ± √16-48] / -2
= -4 ± √-32 / -2

Simple-
One di has 6 sides.
Three sides are even numbers
We are looking for the probability of not having and odd number chosen
It would be 3/6 because there are 3 even numbers and 3 odd numbers, and we are using even numbers because we need to know the probability of not landing on an odd number.

Given the point (x, y) = (3, 8), find x' of the image point with respect to an axis rotated 60.
3/2 + 4√3
(3√3)/2 - 4
(3√3)/2 + 4
The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3
How to determine the x' coordinate?The point is given as:
(x, y) = (3, 8)
The angle of rotation is given as:
θ = 60
The image of rotation is calculated using:
x = x'cosθ - y'sinθ
y = x'sinθ + y'cosθ
So, we have:
3 = x'cos(60) - y'sin(60)
8 = x'sin(60) + y'cos(60)
Evaluate cos(60) and sin(60)
3 = 1/2x' - y'√3/2
8 = x'√3/2 + 1/2y'
Multiply the second equation by √3
8√3 = 3/2x' + √3/2y'
Add this equation and the first equation to eliminate y'
3 + 8√3 = 1/2x' + 3/2x'
Evaluate the sum
3 + 8√3 = 2x'
Divide through by 2
x' = 3/2 + 4√3
Hence, the value of x' is 3/2 + 4√3

Answer:
6^6
Step-by-step explanation:
Divide the terms with the same base by subtracting their exponents.
6^10 - 4 = 6^6
Answer:
6^6, which equals 46656
Step-by-step explanation:
So when dividing things with exponents in them, you subtract the exponents. With this, you would do:
6^10/6^4 = 6^10 - 6^4 ---> 6^6

What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
Given;
Side BA= [tex]\sqrt{11}[/tex]
Side AC= [tex]\sqrt{5}[/tex]
BC^2=BA^2+AC^2
BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2
BC^2= 11+5
BC^2= 16
BC= 4

In a rectangle, the length is 5 more than three times the width. The perimeter is 250cm. Determine the length of each side.
Answer:
l = 95 cm
w = 30 cm
Step-by-step explanation:
w = width
5+3w = length
P = 2l + 2w
250 = 2(5+3w) + 2w
250 = 10 + 6w + 2w
240 = 8w
w = 30
5 + 3(30) = length
