\The lengths of a lawn mower part are approximately normally distributed with a given mean Mu = 4 in. and standard deviation Sig
chubhunter [2.5K]

Answer:

68.26% of the parts will have lengths between 3.8 in. and 4.2 in.

Step-by-step explanation:

The lengths of a lawn mower part are approximately normally distributed

\mu = 4

Standard deviation =\sigma =0.2

We are supposed to find  What percentage of the parts will have lengths between 3.8 in. and 4.2 in . i.e. P(3.8<x<4.2)

Formula : Z=\frac{x-\mu}{\sigma}

At x = 3.8

Z=\frac{3.8-4}{0.2}

Z=-1

Refer the z table for p value

p value =0.1587

At x =4.2

Z=\frac{4.2-4}{0.2}

Z=1

Refer the z table for p value

p value =0.8413

P(3.8<x<4.2)=P(x<4.2)-P(x<3.8)=0.8413-0.1587=0.6826

So, 68.26% of the parts will have lengths between 3.8 in. and 4.2 in.

Novay_Z [31]
Ok you’ll know that it’s 0.31%

Explanation:
The process is start by making it into a fraction, 2/650 then divide 2 by 650 to get 0.0031 (I rounded up) which to make it into a percentage, you move everything two spot closer to the “.”
0.31 then add a % and bam that’s the answer.
Hope this helps!

At the market, Ms. Winn bought 3/4 lb of grapes and 5/8 lb of cherries.
wolverine [178]

Answer:

Part a) Ms. Winn bought 12 oz of grapes

Part b) Ms. Winn bought 10 oz of cherries

Part c) Ms. Winn bought 2 oz more of grapes than cherries

Part d) Mr. Phillips bought 6 more ounces of fruit than Ms. Winn

Step-by-step explanation:

Part a) How many ounces of grapes did Ms. Winn buy?

Remember that

1\ lb=16\ oz

To convert lb to oz multiply by 16

we know that

Ms. Winn bought 3/4 lb of grapes

Convert lb to oz

Multiply by 16

\frac{3}{4}\ lb= \frac{3}{4}(16)=12\ oz

therefore

Ms. Winn bought 12 oz of grapes

Part b) How many ounces of cherries did Ms. Winn buy?

Remember that

1\ lb=16\ oz

To convert lb to oz multiply by 16

we know that

Ms. Winn bought 5/8 lb of cherries

Convert lb to oz

Multiply by 16

\frac{5}{8}\ lb= \frac{5}{8}(16)=10\ oz

therefore

Ms. Winn bought 10 oz of cherries

Part c) How many more ounces of grapes than cherries did Ms. Winn buy?

Subtract the ounces of cherries from the ounces of grapes

so

12\ oz-10\ oz=2\ oz

therefore

Ms. Winn bought 2 oz more of grapes than cherries

Part d) If Mr. Phillips bought 1 3/4 pounds of raspberries, who bought more fruit, Ms. Winn or Mr. Phillips? How many ounces more?

Remember that

1\ lb=16\ oz

To convert lb to oz multiply by 16

we know that

Mr. Phillips bought 1 3/4 pounds of raspberries

Convert mixed number to an improper fraction

1\frac{3}{4}\ lb=\frac{1*4+3}{4}=\frac{7}{4}\ lb

Convert lb to oz

Multiply by 16

\frac{7}{4}\ lb= \frac{7}{4}(16)=28\ oz

Remember that

Ms. Winn bought 12 oz of grapes and 10 oz of cherries

In total Ms. Winn bought

12 oz+10 oz=22 oz -----> total ounces of fruit

so

Mr. Phillips bought 28 oz of fruit

Ms. Winn bought 22 oz of fruit

28\ oz > 22\ oz

Find the difference

(28\ oz-22\ oz)=6\ oz

therefore

Mr. Phillips bought 6 more ounces of fruit than Ms. Winn
