Answer:

$\frac{-27}{56}$

Step-by-step explanation:

First, we will subtract.

[] Let's find common denominators.

8 -> 8, 16, 24, 32, 40, 48, 56, 64, 72, 80

7 -> 7, 14, 21, 28, 35, 42, 49, 56

$\frac{3}{8}=\frac{3*7}{8*7} =\frac{21}{56}$

$\frac{6}{7} =\frac{6*8}{7*8} =\frac{48}{56}$

(multiplying by these numbers does not affect them because, for example, $\frac{8}{8}=1$ )

[] Subtract across the numerators, the denominator stays the same

$\frac{21}{56} -\frac{48}{56} =\frac{-27}{56}$

[] Simplify

-> To simplify, we can find common factors

For 27: 1, 3, 9, and 27

For 56: 1, 2, 4, 7, 8, 14, 28, and 56

-> $\frac{-27}{56}$ does not have any common factors besides one, so it is fully simplified

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Upper H 0: pequals0.6 versus U

kow [346]

Answer:

Step-by-step explanation:

From the given information:

The null and the alternative hypothesis can be well written as:

$H_o:P=0.6$

$H_1:P>0.6$

Given that:

n = 200

x = 135

Alpha ∝ = 0.05 level of significance

Then;

⇒ $n \times p\times (1-P)$

= 200 × 0.6 × (1 -0.6)

= 200 × 0.6 × 0.4

= 48 ≥ 10

The sample proportion $\hat P = \dfrac{x}{n}$

$= \dfrac{135}{200}$

= 0.675

The test statistics $Z = \dfrac{\hat P - P}{\sqrt{ \dfrac{P(1-P)}{n} }}$

$Z = \dfrac{0.675 - 0.6}{\sqrt{ \dfrac{0.6 \times 0.4}{200} }}$

$Z = \dfrac{0.075}{\sqrt{ \dfrac{0.24}{200} }}$

Z = 2.165

The P-value = P(Z > 2.165)

= 1 - P(Z < 2.165)

From the z tables

= 1 - 0.9848

= 0.0152

Reject the null hypothesis since P-Value is lesser than alpha. ( i.e. 0.0152 < 0.05).

Thus, there is enough evidence to conclude that the value of the population proportion is greater than 0.6

If a is an integer and n is a positive integer, we define a mod n to be the remainder when a is divided by n. The integer n is c

dezoksy [38]

Answer:

Divisor

Step-by-step explanation:

Given

$a\ mod\ n$

Required

What does n represents

In arithmetic, the number that divides another is referred to as divisor;

Take for instance;

$5\ mod\ 3 = 2$

This implies that when 5 is divided by 3, the remainder is 2

The bold text (divided by 3) means that 3 is the divisor of 5;

When compared to $a\ mod\ n$

We have that

n = 3

Reason being that, n and 3 are in the same position base on order of appearance;

Hence, n represents the divisor

Elevator 1 in a building moved from ground position to a final position of +13 feet. Elevator 2 in the same building moved from

Marina CMI [18]

The correct answer I believe you are looking for is D. Elevator 1 is 13 feet above ground level, and Elevator 2 is 10 feet below ground level.

Explaination:

This is because if you start at (0, 0) Elevator one, will go up 13 on the y axis. Putting it at 13 feet above ground level. If you start Elevator 2 at ground level on (0, 0) and go down 10 it will make it -10 AKA 10 feet below ground level.

I hope this helps! :)

Delta Math: Finding Angles (Level 1) 1/5 Full explanation please will give brainlist

olga nikolaevna [1]

Answer:

$m\angle FGC =101\degree$

Step-by-step explanation:

$m\angle CBF = 46\degree$ (Given)

$m\angle FIG = 55\degree$ (Given)

$m\angle IFG = m\angle CBF$ (Corresponding angles)

$\implies m\angle IFG = 46\degree$

$m\angle FGC =m\angle IFG+ m\angle FIG$

(By exterior angle theorem)

$m\angle FGC =46\degree+ 55\degree$

$m\angle FGC =101\degree$
