What is the difference between the temperatures at 10 a.m. and 3:30 p.m.? Indicate whether the change is an increase or decrease.

Answer:

There are multiple answers

Step-by-step explanation:

Answer:

An angle measures 130° more than the measure of its supplementary angle.

Therefore the required angle is (180°-130°)°=50°

The measure of the angle is A = 50° and the supplementary angles are given by 130° and 50°

Supplementary angles are two angles that have a sum of 180°.

Complementary angles are two angles that have a sum of 90°.

Given data ,

Let the first angle be represented as A

Now , the value of A is

Let the second angle be represented as B

And , the value of B is B = 130°

The angles A and B are supplementary

So , A + B = 180°

On simplifying , we get

The measure of A + 130° = 180°

Subtracting 130° on both sides , we get

The measure of angle A = 180° - 130°

The measure of angle A = 50°

Hence , the measure of angle is 50°

Answer:

0.0062 = 0.62% probability of this occurring

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 2000, \sigma = 20[/tex]

a. If the process overfills the bottle by more than 50 milliliters, the overflow will cause a machine malfunction. What is the probability of this occurring

Probability of filling the bottle with more than 2000 + 50 = 2050 milliliters, which is 1 subtracted by the pvalue of Z when X = 2050. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{2050 - 2000}{20}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a pvalue of 0.9938

1 - 0.9938 = 0.0062

0.0062 = 0.62% probability of this occurring

ANSWER

0.08 then 0.7 then 8/10 then 81%

Explanation

im going to put everything into fraction because i think it would be easier for u to understand

8/10 > 80/100

0.08> as a fraction is > 8/100

81% as a fraction is 81/100

and last but not least, 0.7 as a fraction is 70/100

so order these from least to greatest

8/100 then 70/100 then 80/100 and then 81/100.

Answer:

7.5

Step-by-step explanation:

The perimeter of the regular pentagon will be 7.5 units.

All the sides of the regular polygon are congruent to each other. The perimeter of the regular polygon of n sides will be the product of the number of the side and the side length of the regular polygon.

P = (Side length) x n

The sides of the regular polygon are 3(x - 1) and (5x - 6). Then the value of the variable x will be

3(x - 1) = 5x - 6

3x - 3 = 5x - 6

2x = 3

x = 1.5

Then the side length of the regular pentagon will be

Side = 3(1.5 - 3)

Side = 3 (0.5)

Side = 1.5

Then the perimeter of the regular pentagon will be

P = 5 x 1.5

P = 7.5 units

The perimeter of the regular pentagon will be 7.5 units.

Answer:

0.7780

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Population:

We have that [tex]\mu = 7.19, \sigma = 0.86[/tex]

Sample of 12:

[tex]n = 12, s = \frac{0.86}{\sqrt{12}} = 0.2483[/tex]

What is the probability that the mean cost will be more than $7.00?

This is 1 subtracted by the pvalue of Z when X = 7. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{7 - 7.19}{0.2483}[/tex]

[tex]Z = -0.765[/tex]

[tex]Z = -0.765[/tex] has a pvalue of 0.222

1 - 0.222 = 0.778

So the answer is 0.7780

Step-by-step explanation:

The equivalent ratios to 6 : 16 are, 3 : 8, 30/80 and 18 to 48.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, A ratio 6 : 16 = 3 : 8.

So, One equivalent ratio is 3 : 8.

Now, Going through options,

10×3 : 10×8.

= 30 : 80.

= 30/80.

6×3 : 6×8.
