Answer:

A.

Step-by-step explanation:

We have the expression [tex]\sqrt{x+4} -3=2[/tex] and are asked which is the first step to solve it.

When doing equations, you always want to isolate x, now since x is stuck in a square root, we need to first get rid of the numbers outside the root. So -3, we would need to add three to both sides first. This step crosses out all other answers and leave us with A.

Answer:

[tex]s = 0.0394[/tex]

Step-by-step explanation:

Given:

0.612 0.523  0.606 0.631  0.584  0.592  0.644  0.597  0.639  0.607  0.564  0.673

Required

Calculate the sample standard deviation

First, calculate the mean

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{0.612 +0.523 +0.606 +0.631+ 0.584 + 0.592+ 0.644 +0.597 +0.639 +0.607 +0.564+ 0.673}{12}[/tex]

[tex]\bar x = \frac{7.272}{12}[/tex]

[tex]\bar x = 0.606[/tex]

The sample standard deviation is then calculated using:

[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

[tex]\sum (x - \bar x)^2 = (0.612 -0.606)^2+(0.523 -0.606)^2+(0.606 -0.606)^2+(0.631 -0.606)^2+(0.584 -0.606)^2+(0.592 -0.606)^2+(0.644 -0.606)^2+(0.597 -0.606)^2+(0.639 -0.606)^2+(0.607 -0.606)^2+(0.564 -0.606)^2+(0.673 -0.606)^2[/tex]

[tex]\sum (x - \bar x)^2 = 0.017098[/tex]

So, we have:

[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

[tex]s = \sqrt{\frac{0.017098}{12-1}}[/tex]

[tex]s = \sqrt{\frac{0.017098}{11}}[/tex]

[tex]s = \sqrt{0.00155436363}[/tex]

[tex]s = 0.0394[/tex] -- approximated

Answer:

[tex]\sqrt{51}[/tex]

Step-by-step explanation:

It's a right triangle so, [tex]a^{2} +b^{2} =c^{2}[/tex]

a=7

c=10

b=?

49+[tex]b^{2}[/tex]=100

100-49=[tex]b^{2}[/tex]

51=[tex]b^{2}[/tex]

b=[tex]\sqrt{51}[/tex]

The required inequality, of a product of a number and -3 increased by 8 is no less than 35 is -3x + 8 ≥ 35.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

here,
Let the number be x,
According to the question,
The product of a number and -3 increased by 8  is no less than 35.
So,
-3x + 8 ≥ 35

Thus, the required inequality, of a product of a number, and -3 increased by 8 is no less than 35 is -3x + 8 ≥ 35.

Answer:

1 3/8 inches

Step-by-step explanation:

Total Length after adding 2 meteors of equal length = 16 inches

Let the length of the added meteor = x

To obtain the total length, we sum of each meteror multiplied by its frequency is obtained ;

(2/8)(1)+(3/8)(3)+(4/8)(2)+(6/8)(2)+(10/8)(1)+(11/8)(2)+(14/8)(2)+(15/8)(1) + 2x = 16

13.25 + 2x = 16

13.25 + 2x = 16

2x = 16 - 13.25

2x = 2.75

x = 1.375

1.375 = 1 3/8
