If you would like to know what is 3/8 written as a percent, you can calculate this using the following steps:

3/8 = 375/1000 = 0.375
0.375 * 100 % = 37.5%

The correct result would be 37.5%.

To convert a fraction to a percentage, multiply it by 100 and add the percent (%) sign.

\frac{3}{8}\times 100 = \frac{300}{8} =\frac{150}{4} =\frac{75}{2} = 37.5

So 3/8 is 37.5%.

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 449.0 gram setting. It
MrRa [10]

Answer:

|Z| = |-1.36| < 1.645 at 0.1 level of significance

The null hypothesis is accepted

A manufacturer of banana chips are filling machine works correctly at the mean 449

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given mean of the Population(μ) = 449

The Standard deviation of the population(σ) = 22

size of the sample 'n' = 36

mean of the sample(x⁻) = 444

Given the level of significance(α) = 0.1

Critical value Z = 1.645

<u><em>Step(ii):</em></u>-

<em>Null hypothesis</em>:H₀:

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 449.0

(μ) = 449

<em>Alternative Hypothesis</em>:H₁: (μ) ≠ 449

Test statistic

                  Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } } \\= \frac{444-449}{\frac{22}{\sqrt{36} } }

                 = -1.36

<em>Final answer:-</em>

|Z| = |-1.36| < 1.645 at 0.1 level of significance

The null hypothesis is accepted

A manufacturer of banana chips are filling machine works correctly at the mean 449

The equation d=3t represents the relationship between the distance (d) in inches that a snail is from a certain rock and the tim
Maksim231197 [3]

Answer:

3 minutes

Step-by-step explanation:

d=3t is our formula.

d being the distance (9 inches for this problem)

t is the time in minutes


Substituting our known information would make our equation look like:

9 = 3t

to solve for t we divide both sides of the equation by 3

9/3 = 3t/3

3 = t


So if a snail travels 3 inches per minute, it will have traveled 9 inches in 3 minutes.

There were some people on a train. 19 people got off the train at the first stop. 17 people get on the train. Now there is 63 pe
maria [59]

Answer:

65 people.

Step-by-step explanation:

We have to work backwards.

We end with 63 people, and at the stop we lost 19 people and gained 17.

x - 19 + 17 = 63\\; if x = # people at the beginning

x - 19 + 17 = 63\\x - 2 = 63\\x = 65

There were 65 people on the train to begin with.
