The diameter of bushings turned out by a manufacturing process is a normally distributed random variable with a mean of 4.035 mm

Andrew [12]

A) the z score for 95% is 1.96

Multiply by the deviation:

1.96 x 0.005 = 0.0098

Now add and then subtract that from the mean:

4.035 - 0.0098 = 4.0252

4.035 + 0.0098 = 4.0448

The interval is (4.0252, 4.0448)

B) 4.035 +/- 1.96 x sqrt( 0.005/sqrt(25))

= 4.035 +/-0.00196

Answer: ( 4.033, 4.037)

C) the conclusion is that both 4.020 and 4.055 are out of the range.

4.020 is below the lowest range and 5.055 is higher than highest range.

A cake recipe requires 3 1/4 cups of flour for 13 servings and 4 1/2 cups of flour for 18 servings.How much flour is required to

slamgirl [31]

To solve, set up a proportion

3.25 cups x cups
---------------- = ---------------
13 servings 28 servings

Now cross multiply

13x = 28 * 3.25

Simplify.

13x = 91

Divide both sides by 13

x = 7 cups

To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct

Franklin weighs 46,266,400 milligrams and his baby brother weighs 4,535.9 grams. What la there total weight in kilograms?

amm1812

Answer:

Exact: 50.8064

Rounded to nearest whole #: 51

Step-by-step explanation:

Our units are: Milligrams, Grams, and Kilograms. For Reference;

Miligrams are 1 million (1,000,000) times smaller than kilos.

Grams are 1 thousand (1,000) times smaller than kilos.

If we divide Franklins weight, 46,266,400 mg, by 1,000,000, our answer is 46.2664 kg, 46 if we round it.

Now, for his baby brother, his weight is 4,535.9 g. Divide this by 1000, and you should get 4.5359 kg, 4.5 if we round it to the nearest tenth.

Now simply add our two answers and you have both of their weight combined.

This is pretty simple, you simply can move the decimal point a certain amount of times dependent on how bigger or smaller your unit is. If we were converting kilograms to grams, we would multiply a value by 1,000, and the inverse for grams to kilograms, which moves the decimal point 3 times.

Any questions? Just ask me. Thanks.
