How do you solve (2x + 8 )2 =64

Drupady [299]

Answer:

x = 12

Step-by-step explanation:

Write in a different way: 2(2x + 8) = 64
Apply the distributed property, so it now looks like this: 4x + 16 = 64
Subtract 16 from each side, so it now looks like this: 4x = 48
Divide each side by 4 to cancel out the 4 next to x. It should now look like this: x = 12

I hope this helps!

A study was recently conducted to estimate the mean cholesterol for adult males over the age of 55 years. From a random sample o

Komok [63]

Answer: Correct critical value = 2.2622

Step-by-step explanation:

Confidence interval for population mean when population standard deviation is unknown:

$\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}$ , where $\overline{x}$ = sample mean, n= sample size, s= sample standard deviation, $t_{\alpha/2}$ = two-tailed t value.

As per given: n= 10

degree of freedom : df = n-1=9

$\overline{x}=242.6\\\\s=73.33\\\\\alpha=5\%=0.05$

Critical t-value : $t_{\alpha/2,df}=t_{0.05/2,9}=t_{0.025,9}=2.2622$

So, the 95 percent confidence interval estimate for the mean :

$242.6\pm (2.2622)\dfrac{73.33}{\sqrt{10}}\\\\=242.6\pm (2.2622)(23.19)\\\\\approx242.6\pm52.46\\\\=(242.6-52.46,\ 242.6+52.46)\\\\=(190.14,\ 295.06)$

The 95 percent confidence interval estimate for the mean:(190.14, 295.06)

The Oliver Company plans to market a new product. Based on its market studies, Oliver estimates that it can sell up to 5,500 uni

Ghella [55]

For the Oliver Company to break even, the total revenue must equal the sum of the variable costs and the fixed cost. Mathematically, this can be represented as: Total revenue = 0.4*(Total revenue) + (Fixed Costs) Let the number of units sold be x. then, 7*x = 0.4*(7*x) + 6300 Thus, x = 6300/(0.6*7) = 1500 units. Thus the company will have to sell 1500 units to break even.

1. h(2) + g(2) * h(t) = 3-5 g(t) = 2t - 5

kap26 [50]

Answer:

h(2)+g(2) = -3

Step-by-step explanation:

$h(2) +g(2)\\ \\h(t) = 3-5, g(t) = 2t -5$

Replace the variable (t) with (

2) in the expression.

h (2) = 3 - 5

Replace the variable (t) with (

2) in the expression.

g(2) = 2(2) -5

Replace the function designators in h(2) +g(2) with the actual functions.

h(t) = 3 - 5 +2 (2) ← plug h(2) into 2(t)

Remove parentheses.

3 - 5 + 2(2)

Multiply 2 by 2

3 - 5 + 4 - 5

Subtract 5 from 3

-2 + 4 - 5

Add -2 and 4

2 - 5

Subtract 5 from 2

-3
