Yes, it is correct
alexgriva [62]

Answer:In Heather's solution to the problem, she wrote and solved an equation.

Her work is:

Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87

Solving like terms

1.08(x+15}=21.87

dividing both side by 1.08

we get

x+15=21.87/1.08

x+15=20.25

subtracting both side by 13.9198

x=20.25-15

x=5.25

According to correction

;

<u>Option 1st</u>

<u>yes,it is correct</u>

Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:
Roman55 [17]

The confidence interval can be calculated from the margin of error, and vice versa,

The margin of error of the confidence interval is 2.156

The confidence interval is given as:

\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}

The formula of confidence interval is:

\mathbf{CI = \bar x\pm E}

Where E represents the margin of error.

So, by comparison:

\mathbf{E = 1.96 \cdot 1.1}

Multiply

\mathbf{E = 2.156}

Hence, the margin of error of the confidence interval is 2.156

Solve the compound inequality.
aivan3 [116]

Option D:

x

Solution:

Given compound inequality:

6-x>15 \text { or } 2 x-9 \geq 3

Let us first solve 6-x>15.

Subtract 6 from both sides.

6-x-6>15-6

-x>9

To reverse the inequality multiply by -1  on both sides.

(-x)(-1)

x

Now solve the next inequality 2 x-9 \geq 3.

Add 9 on both sides.

2 x-9+9 \geq 3+9

2 x \geq 12

Divide by 2 on both sides.

$\frac{2 x}{2} \geq \frac{12}{2}

x \geq 6

Combine the inequality.

x

Option D is the correct answer.
