Hello from MrBillDoesMath!

Answer:

The fourth choice, b = +\- sqrt( sg + a^2)

Discussion:

s = (b^2 - a^2)/g => multiply both sides by "g"

sg = b^2 - a^2 => add a^2 to both sides

sg + a^2 = b^2 => take the square root of each side

b = +\- sqrt( sg + a^2)

which is the fourth choice.

Thank you,

MrB

Solve for the equation, show all your work. This is an absolute value equation. You need to show both equations and the work for

VMariaS [17]

Answer:

$x=-1$ or $7$

Step-by-step explanation:

We use casework on when $3x-9=12$ and when $3x-9=-12$ .

For the first case, $3x-9=12$ , we add 9 to both sides to get

$3x=21$ .

Dividing both sides by 3 gives

$x=7.$

For the second case, $3x-9=-12$ , we add 9 to both sides to get

$3x=-3$ .

Dividing both sides by 3 gives

$x=-1$ .

Checking both cases, we plug in $x=7$ and $x=-1$ .

For the first case, we have $|3(7)-9|=|21-9|=|12|=12$ , which satisfies the equation.

For the second case, we have $|3(-1)-9|=|-3-9|=|-12|=12$ , which also satisfies the equation.

This gives us two solutions to the equation; $x=7$ and $x=-1$ .

Determine the point estimate of the population mean and margin of error for the confidence interval with lower bound 7 and upper

djverab [1.8K]

Answer:

Point estimate is 16 and Margin of error is 9

Step-by-step explanation:

The point estimate is given by the following formula:

Point estimate = (Lower Bound + Upper Bound) / 2

Replacing we have:

Point estimate = (7 + 25) / 2 = 32/2

Point estimate = 16

Now, the margin of error is given by the following equation:

Margin of error = (Upper Bound - Lower Bound) / 2

Margin of error = (25 -7) / 2 = 18/2

Margin of error = 9

1 + (3)(9)

pychu [463]

The person went wrong on step 2

Should be

11 + (9)(3)= x

11 + 27= x

x = 38

PLEASE HELP!! WILL GIVE BRAINLIEST!!!

Murrr4er [49]

Answer:

option D

Step-by-step explanation:

Jerry solved this equation:

$3(x-\frac{1}{4})=\frac{13}{6}$

In the first step , she multiplied 3 inside the parenthesis

1. $3x-\frac{3}{4}=\frac{13}{6}$

In step 2, 3/4 is added on both sides

2. $3x-\frac{3}{4}+\frac{3}{4}=\frac{13}{6}+\frac{3}{4}$

In step 3, we take LCD 12

3. $3x=\frac{26}{12}+\frac{9}{12}$

In step 4, add the fractions

4. $3x=\frac{35}{12}$

Here, 3 or 3/1 are same.

$\frac{3}{1}x=\frac{35}{12}$

In step 5, to remove 3/1 we multiply both sides by 1/3.

Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1

$\frac{1}{3} \cdot \frac{3}{1}x=\frac{1}{3} \cdot \frac{35}{12}$

$x=\frac{35}{36}$

In step 5, he should have multiplied both sides by 1/3
