Karina owns a bakery where she orders both green apples and red apples to use in her baked goods. The supplier of the green apples says that 8% of their green apples are bruised. The supplier of the red apples says that 6% of their red apples are bruised.

Each week, Karina orders 120 of each type of apple, and she looks at the difference (Green−Red) between the proportions of apples with bruises in each order.

What will be the shape of the sampling distribution of the difference in sample proportions, and why?

A. Approximately normal, because we expect 10 bruised and 110not-bruised in both orders, and all of these counts are at least 10.
B. Approximately normal, because we expect 16 bruised and 104 not-bruised green apples, and 12 and 108 for the red apples, and all of these counts are at least 10
C. Not normal, because we expect fewer than 10 bruised apples in both orders.
D. Not normal, because we expect fewer than 10 not-bruised apples in both orders.

Answer: £180

Step-by-step explanation:

The interest gotten for the 10 years will be calculated as:

= Principal × Rate × Time

= 150 × 2% × 10

= 150 × 0.02 × 10

= 30

The amount he has in the bank account at the end of the 10 year will be:

= Principal + Interest

= £150 + £30

= £180

The answer is  [tex]\frac{5}{10}[/tex]

And that is correct

Answer:

B

Step-by-step explanation:

Answer:

t = 2 s and t = 4 s

Step-by-step explanation:

A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by,

[tex]f (t) = -16t^2 + 96t[/tex]

We need to find in how many seconds will the rocket be at a height of 128 ft above the ground.

It means,

[tex]128= -16t^2 + 96t\\\\-16t^2+96t-128=0\\\\16(-t^2+6t-8)=0\\\\(-t^2+6t-8)=0\\\\-t^2+4t+2t-8=0\\\\t(-t+4)-2(-t+4)=0\\\\(t-2)=0\ and\ (-t+4)=0\\\\t=2\ and\ t=4[/tex]

So, it will be at a height of 128 feet at 2 second and 4 second.

Answer:B

Step-by-step explanation:

2.45(0.35)= 0.8575+2.45= 3.30

Answer:

20 inches.

Step-by-step explanation:

We equate the perimeters:

5(x - 2) = 4(1/2x + 2)

5x - 10 = 2x + 8

5x - 2x = 8 + 10

3x = 18

x = 6

The perimeters = 5(6-2)

= 20 inches.

Answer:

x=3 and 9

Step-by-step explanation:

; x-3=0

x=3 (change side change mark)

and

[tex] \frac{2}{3} x - 6 = 0[/tex]

[tex] \frac{2}{3} x = 6[/tex]

[tex]x = 6 \times \frac{3}{2} [/tex]

change side change mark.

So, x=9

If u wanna check the answer you can check by substitution x=3 and 9 in equation.

hope it helps you ☺️

Answer:

120 seats

Step-by-step explanation:

Total seats in the hall = 300

Percentage of filled seats = 60 %

Number of seats filled = (60 / 100) 300

                                     = 60 * 3

                                     = 180

Therefore, number of empty seats = 300 - 180

                                                          = 120

Step-by-step explanation:

you simply add the 2 smaller sides, and if their sum equals the bigger side, its correct!

Answer:

x=1 y=2

Step-by-step explanation:

y=4-2x             3y=4+2x

3*(4-2x)=4+2x

12-6x=4+2x

12-4=2x+6x

8x=8

x=1

y=4-2*1

y=2

Answer:

0.4

Step-by-step explanation:

Given that:

Probability of :

Red _____Green ___ Brown _____ Yellow

0.2 ______ 0.3 ______ X ________ 0.1

Since the bag contains only red, green, brown and yellow marbles ;

The sum of each color's probability should sum up to 1;

ΣP(x) = 1

Hence,

0.2 + 0.3 + x + 0.1 = 1

0.6 + x = 1

x = 1 - 0.6

x = 0.4

P(brown) = 0.4

Answer:

20

Using the formula of Pythagoras theorum 20 is the answer.

Answer:

yes

Step-by-step explanation:

you can use the vertical line test- for every line going up and down there should only be one point. if there is one and only one, it's a function. if there are more than one per line, then it is not a function.

Answer:

Slope(m)=2x

y-intercept(b)=3

Step-by-step explanation:

Answer:

Slope is -2x, Y-Intercept is 3

Step-by-step explanation:

You need to isolate the "y" to get the answer, all you need to do is subtract the "2x" from both sides

Answer:

Step-by-step explanation:Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

Hope this helps :-)Area = 1/2(b1 + b2)x h

Area = 18,000 ft^2

b1 = 80 ft

b2 = 100 ft

18,000 = 1/2(80 + 100) x h

36,000 = (180)h

h = 36,000/180

h = 200ft.

This is the distance between streets.

Hope this helps :-)

Answer:

Step-by-step explanation:

Add '-2a' to each side of the equation.

5a + -2a = -6 + 2a + -2a

Combine like terms: 5a + -2a = 3a

3a = -6 + 2a + -2a

Combine like terms: 2a + -2a = 0

3a = -6 + 0

3a = -6

Divide each side by '3'.

a = -2

Simplifying

a = -2

5a -2a -6

3a -6

Answer:

D. 3/2, -9

Step-by-step explanation:

First, rearrange the equation 3x - 2y = 18 into the slope-intercept form of y = mx + b:

3x - 2y = 18

2y = 3x - 18

y = 3x/2 - 9

from this, u can tell that the slope is 3/2 and the y-intercept is -9 (option D)
