Find the measure of each angle indicated.

Answer:

a is 10 and b is 100

Step-by-step explanation:

(a)- if you take 10 to the tenth power you'll get 100

(b)- if you take 100 to the 100th power you'll get 10,000

Answer:

Well it’s asking to find 25 percent of 52

So in order to find this you can multiply 52 by 0.25

When done you should get 13

Using the normal distribution and the central limit theorem, it is found that there is an approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

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

In this problem:

The probability is the p-value of Z when X = 122, hence:

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

By the Central Limit Theorem

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

[tex]Z = \frac{122 - 140}{3}[/tex]

[tex]Z = -6[/tex]

[tex]Z = -6[/tex] has a p-value of 0.

Approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.

Using the z-distribution, it is found that since the absolute value of the test statistic is greater than the critical value, the null hypothesis is rejected.

At the null hypothesis, we test if the proportions are the same, that is, their subtraction is 0, hence:

[tex]H_0: p_1 - p_2 = 0[/tex]

At the alternative hypothesis, it is tested if they are different, that is, their subtraction is not 0, hence:

[tex]H_1: p_1 - p_2 \neq 0[/tex]

The proportions and their respective standard errors are given by:

[tex]p_1 = 0.25, s_1 = \sqrt{\frac{0.25(0.75)}{120}} = 0.0395[/tex]

[tex]p_2 = 0.37, s_2 = \sqrt{\frac{0.37(0.63)}{150}} = 0.0394[/tex]

For the distribution of the difference, the mean and the standard error are given by:

[tex]\overline{p} = p_2 - p_1 = 0.37 - 0.25 = 0.12[/tex]

[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0395^2 + 0.0394^2} = 0.0558[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{s}[/tex]

In which [tex]p = 0[/tex] is the value tested at the null hypothesis.

Hence:

[tex]z = \frac{\overline{p} - p}{s}[/tex]

[tex]z = \frac{0.12 - 0}{0.0558}[/tex]

[tex]z = 2.15[/tex]

The critical value for a two-tailed test, as we are testing if two values are different, with a significance level of 0.15 is [tex]|z^{\ast}| = 1.4395[/tex].

Since the absolute value of the test statistic is greater than the critical value, the null hypothesis is rejected.

Answer:

  19.9 cm

Step-by-step explanation:

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs.

  h² = 19² +6² = 361 +36 = 397

  h = √397 ≈ 19.9

The measure of the hypotenuse is about 19.9 cm.

Answer: 3 tons

Step-by-step explanation: first I figured out how much 2 tons was which is 4000 pounds and then I divided 4000 by 8 which told me that each foot can hold 500 pounds So then I just did 500×10 which is 5000 pounds which is 3 tons

If an 8-foot column can hold 2 tons, then a 10-foot column can hold 1.28 tons.

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, The maximum weight that a circular column can hold is inversely proportional to the square of its height.

∴ w ∝ 1/h² or w = k(1/h²).

An 8-foot column can hold 2 tons which is,

2 = k(1/8²).

2 = k(1/64).

k = 128.

Now, 10 feet column can hold,

w = 128(1/10²).

w = 128/100.

w = 1.28 tons.

Step-by-step explanation:

I did the quiz

The expressions equivalent to 3 (6e + 4) + 8 (e + 2) + 6e are : 4(8e + 7) And 28 + 32e

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions. To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

Given the expression as;

3 (6e + 4) +8 (e + 2) + 6e.

Expand the brackets ;

18e + 12 + 8e + 16 + 6e

Now Collect like terms together and simplify;

=18e + 8e + 6e + 12 + 16

=32e + 28

=28 + 32e

Then factorizing the result, we have;

32e + 28 = 4(8e + 7)

The expressions equivalent to 3 (6e + 4) + 8 (e + 2) + 6e are : 4(8e + 7) And 28 + 32e

Explanation:

A decrease of 17% means that he made 100% - 17% = 83% of what he did last year.

83% = 83/100 = 0.83

83% of $55,000 = 0.83*55000 = 45,650 dollars

Put the number being divided over the dividend as a fraction.

Step-by-step explanation:

Answer:

Here are a few useful simplified division tips: If the dividend and divisor are both even numbers, try dividing them first by 2. For example, if you've got to divide 196/22, divide them by 2 first. When you have 98/11, you'll find it easier to figure out the rest of it with the smaller numbers.

Step-by-step explanation:

Divide by 1 - Anytime you divide by 1, the answer is the same as the dividend.

Divide by 2 - If the last digit in the number is even, then the entire number is divisible by 2.

Divide by 4 - If the last two digits divide by 4, then the entire number is divisible by 4.

One way to start is to divide by the first prime until you can't do that any more, then try the next prime and so on until all the numbers in your list are prime.

40 = 2(20)  divide 20 by 2 again

40 = 2(2)(10)  divide 10 by 2 again
