Part A: If (6²)x = 1, what is the value of x? Explain your answer. (5 points)

aleksandr82 [10.1K]

Answer:

A: x = 1/36

B: x = 1

Step-by-step explanation:

Part A:

(6²)x = 1

6² = 36, so we write 36 instead of 6² and get:

36x = 1

Now we divide both sides by 36 to find the value of x.

x = 1/36

Part B:

(6ˆ0)x = 1

6^0 = 1, so we replace 6^0 with 1 in the equation and get:

1x = 1

1x is the same as x, so our solution is:

x = 1

Can someone help me with this question please.....

Alex73 [517]

Answer:

y = 541

Step-by-step explanation:

The mean is calculated as

mean = $\frac{sum}{count}$

Mean of set A = $\frac{281+268+225+290}{4}$ = $\frac{1064}{4}$ = 266

ratio between means = 7 : 12, then

mean of set B = $\frac{12}{7}$ × 266 = 456 , thus

$\frac{392+512+413+422+y}{5}$ = 456 ( multiply both sides by 5 )

1739 + y = 2280 ( subtract 1739 from both sides )

y = 541
