700×24

=16,800

16,800+6,000

=22,800

22,800-20000

so its 2800

Hope its right! Give brainliest :)

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:

2 x 2 x 2 x 5

Step-by-step explanation:

The first few prime numbers:  {2, 3, 5, 7, 11, 13, 17, 19}

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

40 = 2(2)(2)(5) stop--all factors are prime.

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

  $2352

Step-by-step explanation:

The second formula applies for continuous compounding. You have ...

  P = $1500, r = 0.0225, t = 20

Then ...

  A = $1500e^(0.0225·20) ≈ $2352

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.

Factoring: x2 - 4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A² - AB + BA - B² =

A² - AB + AB - B² =

A² - B²

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : x2 is the square of x1

Factorization is : (x + 2) • (x - 2)
