A brand of frozen green beans lists a weight of 32

ounces on its bag. Because of variability in the

manufacturing process, the bags often contain slightly

more, or less, than 32 ounces of green beans. An

inspector takes a random sample of 25 bags of green

beans and records their weights. The weights and their

relative frequencies are summarized in the histogram

below.

Which is true about the bags of green beans in the sample?

a- twenty percent of the bags have a weight below 32.2 ounces

b- sixty percent of the bags have a weight over 32.2 ounces

c- eighty percent of the bags have a weight over 32.2 ounces

d- the interval from 32.3 to 32.4 contains the highest proportion of bags

Answers

I think the answer is B

Answer:

sixty percent of the bags have a weight over 32.2 ounces

Step-by-step explanation:

answer is B

7 - 2x - 5y=-7
3x + 4y = 7

Answers

-7 + 7 = 0
-5y = 2x
-5y/5 = y
2x/5 = 2x/5

y = 2x/5

4y = -3x + 7

4y/4 = y

-3x/4 + 7/4

y = -3x/4 + 7/4

If 10% of a number is 36 and 55% of the same number is 198, find 45% of that number.

Answers

9514 1404 393

Answer:

162

Step-by-step explanation:

There are many ways to work this. Perhaps the simplest is to recognize that 45% of the number is the difference between 55% of it and 10% of it.

0.55n -0.10n = 0.45n

198 -36 = 0.45n = 162

45% of the number is 162.

_____

If you like, you can find the number as ...

0.10n = 36

n = 36/0.10 = 360

Then you can verify (if you like), that 55% of it is 198:

0.55(360) = 198 . . . . true

Finally, you can figure 45% of it:

0.45(360) = 162

Using proportions, you can determine the number to be ...

36/0.10 = n/0.45

n = 0.45(36/0.10) = 4.5(36) = 162

Answer:

a) p = 10.20

Step-by-step explanation:

Step(i):-

Given that p varies directly as q

p ∝ q

⇒ p = k q

where 'K' is proportionally constant

given p =20.8 and q = 31.2

p = k q

⇒ 20.8 = k (31.2)

[tex]k = \frac{20.8}{31.2}[/tex]

k = 0.666

Step(ii):-

p = k q

Given that q = 15.3 and k = 0.666

p = 0.666 ×15.3 = 10.20

The Tanners have received an $8000 gift from one of their parents to invest in their child’s college education. they estimate that they will need $20000 in 12 years to achieve their educational goals for their child. What interest rate compounded semiannually would the Tanners need to achieve this goal?

Answers

Answer:

3.4%

Step-by-step explanation:

For given problem:

P=8000

n=2*12=24 compounding perods

A=12000

A/P=(1+i)^24

12000/8000=(1+i)^24

1.5=(1+i)^24

take log of both sides

log1.5=24log(1+i)

log1.5/24=log(1+i)

.007337=log(1+i)

10^(.007337)=1+i

1+i=1.017

i=1.017-1=.017 (interest rate per compounding period)

annual interest rate=2*.017=.034 or 3.4%

1. A school store sells pencils and erasers before school opens each day. On Monday, 13 pencils and

10 erasers were sold for $16.75. On Tuesday, 25 pencils and 2 erasen were sold for $19.85. What

is the price of a pencil? What is the price of an eraser.

Answers

Answer:

price of pencil is 0.74 and eraser is 0.72$

Step-by-step explanation:

Let, "p" represent pencils

and "e" represents erasers.

hence, according to question

13p+10e=16.75 ________(1)

and 25p+2e=19.85________(2)

Multiplying equation (2) by 5,

hence, 125p+10e=99.25________(3)

Substracting equation (3) and (1)

125p+10e-(13p+10e)=99.25-16.75

hence, 112p=82.5

p=0.74

substituting the value in equation (1),

13(0.74)+10e=16.75

9.57+10e=16.75

on solving,

e=0.72

hence, price of one pencil is 0.75$, and price of one eraser is $0.72
