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.

Answers

Answer 1

Answer:

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.

Hope this answer helped! :)

Answer:

obtuse isosceles

Step-by-step explanation:

An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.

C

D
4x+2y=8

−4x−2y=−10

Answers

Answer: B.

[tex]4x - 2y = 8\\-4x + 2y = -8[/tex]

Step-by-step explanation:

Let's solve your system by elimination.

4x−2y=8;−2x+2y=6

Add these equations to eliminate y:

4x-2y=8

-2x+2y=6

2x=14

Substitute 7 for x in 4x−2y=8:

(4)(7)−2y=8

−2y+28=8 (Simplify both sides of the equation)

−2y+28+−28=8+−28 (Add -28 to both sides)

−2y=−20

−2y/−2=−20/−2 (Divide both sides by -2)

y=10

Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?

Answers

Answer:

There are 25 students in the class.

Step-by-step explanation:

Let the total number of students in the class= x

No. of students who passed the test = 18 = 72% of x = 72x/100

Therefore, 72x/100=18

=72x=18*100=1800

=x=1800/72= 25 students.

Hence, total number of students in the class= 25 students

Rewrite in vertex form y=x2+2x+6

Answers

Answer:

y = (x+1)^2+5

Step-by-step explanation:

Add or subtract from both sides to complete the square;

y=x^2+2x+6; Subtract 5 from both sides

y-5 = x^2+2x+1; Factor;

y - 5 = (x+1)^2; Add 5 back to both sides;

y = (x+1)^2+5

Answer:

y=(x+1)²+5

Step-by-step explanation:

y=x^2+2x+6

a=1; b=2;c=6

subtract 6 from both sides: x^2+2x= -6

complete the square by using the equation (b/2)^2 and add to both sides: x^2+2x+1=-6+1

simplify: x^2+2x+1=-5

find the factors of 1 that add up to 2: 1 and 1

(x+1)(x+1)=-5

add 5 to both sides and simplify

y=(x+1)^2+5

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?

Answers

Answer:

40 waves

Step-by-step explanation:

Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%

Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40

Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.

The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.21, 0.30, 0.41, 0.08. Company B A 5-column table has 2 labeled rows. The first row is labeled Number defective (x) with entries 0, 1, 2, 3. The second row is labeled P (x i) with entries 0.18, 0.32, 0.28, 0.22. What is the expected number of defective circuit boards for company A? What is the expected number of defective circuit boards for company B? Which company should be chosen for purchasing circuit boards? Explain.

Answers

Answer: company A: 1.36

company B: 1.54 A; lowest expected number of defective boards

Step-by-step explanation:

i got it right on edge

The weighted average is a generalization of the expected value. The company that should be chosen for purchasing circuit boards is Company A.

What is the expected value?

The weighted average is a generalization of the expected value. The expected value is the arithmetic mean of a large number of independently chosen random variable outcomes.

A.) The expected number of defective circuit boards for company A is,

Expected number = (0.21×0) + (0.30×1) + (0.41×2) + (0.08×3) = 1.36

B.) The expected number of defective circuit boards for company B is,

Expected number = (0.18×0) + (0.32×1) + (0.28×2) + (0.22×3) = 1.54

C.) Since the expected number of defective circuit boards for Company A is less, therefore, the company that should be chosen for purchasing circuit boards is Company A.

I need help with this question please help me

Answers

Hi, so in order to graph you need to know what all those numbers mean.

The -1/2x is the slope or the rise/rub
The -3 is the y-intercept

So start by placing the y-intercept (0,-3), then from there place the slope (-1/2), since the slope is negative instead of going up one and two to the left you are going to go down one and two to the right, then place a point and repeat. After repeating 2-3 times you should be able to connect the points in order to make a line. If you have any questions let me know!
