Answer:

p(x) = 256 \\ p(x) =  {2}^{(x + 2)}  \\  {2}^{(x + 2)}  = 256 \\  {2}^{(x + 2)}  =  {2}^{8}  \\( x + 2) = 8 \\ x =( 8 - 2) \\  \boxed{x = 6}

<h3><u>x=6 </u>is the right answer.</h3>

243 =  {3}^{(x + 3)}  \\  {3}^{(x + 3)}  =  {3}^{5}  \\ (x + 3) = 5 \\ x = (5 - 3) \\ \boxed{ x = 2}

<h3><u>x=2</u> is the right answer.</h3>

Step-by-step explanation:

4) p(x)=256

p(x)=2 ^ x+2

256=2 ^ x+2

2⁸= 2 ^ x+2

8=x+2

x=8-2=6

5)243=3 ^ x+3

3×3×3×3×3 = 3 ^ x+3

3⁵= 3^ x+3

5 = x+3

x=5-3=2

35a+10 just think about the 5 times table

Divide by 5

35a/5= 7a

10/5= 2

35a+10=5( 7a+2)

Answer: 35a+10=5( 7a+2)

N76 [4]

Answer:

Please see the answers below:

Step-by-step explanation:

5

<em>Cost of the Calculator = $65 </em>

<em>Sales Tax added = 6% </em>

Total Price = t = Cost of the Calculator + (Sales Tax Added x Cost of Calculator)

t = $65 + (0.06 x $65)

t = $65 + $3.90

Total Price = t = 68.90

6

a. When there is a sale it means that there is a discount the products offered by store. Here store is offering sale on everything with 10% off, it means that the store is offering a discount of 10% on everything. We can calculate discount price by multiplying the percent discount by the original price, then subtract the result from original price. The new price is the sale price. We will have the equation:

s = r - 0.10r

s = 0.9r

b. A proportional relationship is one in which two quantities vary directly with each other. We say the variable s varies directly as r if:

s = 0.9r

So, yes there is a proportional relationship as the sale price s is proportional to the regular price r purchased at a constant discount rate 0.9.

7

<em>Cost Price = $40 </em>

<em>Mark up % = 25% = 0.25 </em>

<em>Sale Price = s = ? </em>

Sale Price = Cost Price + Markup

s = Cost + (Mark up % x Cost)

s = $40 + (0.25 x $40)

s = $40 + $10

s = $50

The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distr
Alex73 [517]

Answer:

The value of the standardized z-test statistic is -6.4.

Step-by-step explanation:

The test statistic is:

z = \frac{X - \mu}{s}

In which X is the sample mean, \mu is the value tested at the null hypothesis, and s is the standard error.

0.28 is tested at the null hypothesis:

This means that \mu = 0.28

p ^ 0.216 with SE 0.01

This means that X = 0.216, s = 0.01

Then

z = \frac{X - \mu}{s}

z = \frac{0.216 - 0.28}{0.01}

z = -6.4

The value of the standardized z-test statistic is -6.4.
