Answer:

25/8 or 3 1/8

Step-by-step explanation:

5/8 * 5/1 (aka 5)

5/1 equals to 5 because any whole number over 1 equals the same whole number.

To multiply fractions, just multiply across. In the case. 5 time 5 for the numerator. Then 8 times 1 for the denominator.

= 25/8 = 3 1/8

Calibrating a scale:

lana66690 [7]

Answer:

We conclude that the calibration point is set too high.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 1000 grams

Sample mean, $\bar{x}$ = 1001.1 grams

Sample size, n = 50

Alpha, α = 0.05

Population standard deviation, σ = 2.8 grams

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 1000\text{ grams}\\H_A: \mu > 1000\text{ grams}$

We use One-tailed(right) z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{ 1001.1 - 1000}{\frac{2.8}{\sqrt{50}} } = 2.778$

Now, $z_{critical} \text{ at 0.01 level of significance } = 2.326$

Since,

$z_{stat} > z_{critical}$

We reject the null hypothesis and accept the alternate hypothesis. We accept the alternate hypothesis. We conclude that the calibration point is set too high.

A baby blue whale gains about 200 pounds each day about how many pounds does a baby blue whale gain per hour?

Thepotemich [5.8K]

Since there are 24 hours in a day and you want to figure out how many pounds a baby blue whale gains per hour you divide 200 by 24. You should get 8.3 as you answer. Hope I helped with that!
