Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard devia

PSYCHO15rus [73]

Using the normal distribution, it is found that the two readings that are cutoff values separating the rejected thermometers from the others are -1.96ºC and 1.96ºC.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 0, \sigma = 1$ .

The z-score that cuts off the bottom and top 2.5% of the distribution is $z = \pm 1.96$ , hence:

$Z = \frac{X - \mu}{\sigma}$

$-1.96 = \frac{X - 0}{1}$

X = -1.96

$Z = \frac{X - \mu}{\sigma}$

$1.96 = \frac{X - 0}{1}$

X = 1.96

The two readings that are cutoff values separating the rejected thermometers from the others are -1.96ºC and 1.96ºC.

Use mental math to find the equations that are true. Select all that apply. A. 400 ÷ 80 = 50 B. 4 , 000 ÷ 80 = 5 C. 400 ÷ 8 = 50

NeX [460]

As per the mental math calculation, the correct division equations are

C. 400 ÷ 8 = 50

D. 40,000 ÷ 800 = 50

E. 40,000 ÷ 80 = 50

Mental math calculation:

Mental math calculation means a group of skills that allow people to do math “in their head” without using pencil and paper or a calculator.

We can done any type of calculation like addition, subtraction, division etc. based on this method.

Given,

Here we have the following equations,

A. 400 ÷ 80 = 50

B. 4 , 000 ÷ 80 = 5

C. 400 ÷ 8 = 50

D. 40 , 000 ÷ 800 = 50

E. 40 , 000 ÷ 80 = 500

And we need to find the equations that are true by using the mental math calculation.

While we looking into the given expressions,

A. 400 ÷ 80 = 50

This one is false because when we cancel zero, and divide it we get 5 alone.

Then the next one is,

B. 4,000 ÷ 80 = 5

This one is false because when we cancel zero, and divide it we get 50 alone.

Third one is

C. 400 ÷ 8 = 50

This one is true because when we cancel zero, and divide it we get 50 as result.

Next is,

D. 40,000 ÷ 800 = 50

This one is true because when we cancel zero, and divide it we get 50 as result.

Final one,

D. 40,000 ÷ 80 = 500

This one is true because when we cancel zero, and divide it we get 500 as result.

Therefore, options C, D and E are true.
