Answer:

m∠BOC = 60°

Step-by-step explanation:

m∠AOB and m∠BOC have to add up to m∠AOC.

Step 1: Define

m∠AOB = 7x + 30

m∠BOC = 9x + 42

m∠AOC = 104

Step 2: Set up

7x + 30 + 9x + 42 = 104

Step 3: Solve for <em>x</em>

<u>Combine like terms:</u> 16x + 72 = 104

<u>Subtract 72 on both sides:</u> 16x = 32

<u>Divide both sides by 16:</u> x = 2

Step 4: Find m∠BOC

m∠BOC = 9(2) + 42

m∠BOC = 18 + 42

m∠BOC = 60°

<h3>Answer ↓</h3>

<h3>Calculations ↓</h3>

In order to make a the subject of this equation , we need to get a by itself .

The current equation is :

v = u + at

Subtract u on both sides :

v-u=at

Now, divide by t on both sides :

v-u/t=a

<h3>So the formula looks like ↓</h3>

Find the value of x. Enter your answer in the box.

Anton [14]

Answer:

x = $\frac{3}{2}$

Step-by-step explanation:

The figures are similar, thus the ratios of corresponding sides are equal, that is

$\frac{8}{3}$ = $\frac{4}{x}$ ( cross- multiply )

8x = 12 ( divide both sides by 8 )

x = $\frac{12}{8}$ = $\frac{3}{2}$ = 1.5

What is the equation of a line that is parallel to 2x+3y=3 and passes through the point (3, −4) ? Enter your answer in the box.

adell [148]

(3,-4) is your x and y. Plug it in the equation so,

For x,

2x+3y=3
2x+3(-4)=3
2x-12=3
2x=12+3
2x=15
2x/2=15/2
x=7.5

For y,

2(3)+3y=3
6+3y=3
3y=-6+3
3y=-3
3y/3=-3/3
y= -1

Given values: 54, 65, 76, 43, 45, 76, 87 12, 23, 34, 67,65, 78, 45, 34. Given 95% confidence and sigma (population standard devi

Brums [2.3K]

Answer:

Option (D) None of the above.

Step-by-step explanation:

We are given the following data:

54, 65, 76, 43, 45, 76, 87, 12, 23, 34, 67,65, 78, 45, 34

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{804}{15} = 53.6$

Sum of squares of differences = 0.16 + 129.96 + 501.76 + 112.36 + 73.96 + 501.76 + 1115.56 + 1730.56 + 936.36 + 384.16 + 179.56 + 129.96 + 595.36 + 73.96 + 384.16 = 6849.6

$S.D = \sqrt{\frac{6849.6}{15}} = 21.4$
