Find the value of x in 4^x=1/16

Step-by-step answer

P Answered by Master

$x = \frac{1}{64}$

Step-by-step explanation:

$\frac{4x}{1} = \frac{1}{16}$

Then you CROSS MULTIPLY.

WHICH IS.

4x × 16 = 1

64x = 1

Then you divide both sides by coefficient of x which is 64.

$\frac{64x}{64} = \frac{1}{64}$

x = 1/64

Suppose we have two thermometers. One thermometer is very precise but is delicate and heavy (X). We have another thermometer that is much cheaper and lighter, but of unknown precision (Y). We would like to know if we can (reliably) bring the lighter thermometer with us into the field. So, we set up an experiment where we expose both thermometers to 31 different temperatures and measure the temperature with each. We get the following observations: x = 0, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96,

Step-by-step explanation:

(a) H0: μ_D=0

Ha: μ_D ≠ 0

b) Find attached the solution

(c) By technology,

p - value = 0.4437

Hence, the p-value is 0.4437

Miguel wrote the predicted and residual values for a data set using the line of best fit y = 1.82x – 4.3. He left out two of the values. A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries negative 2.3, negative 0.9, 1.1, 3.1. The third column is labeled predicted value with entries negative 2.48, negative 0.66, a, 2.98. The fourth column is labeled residual value with entries 0.18, negative 0.24, negative 0.06, b. Which represents the missing values of a and b? a

Part 5) we have

-25(x-4)=-55(x-10)

solve for x

-25x+100=-55x+550

30x=450

x=450/30

x=15

Part 6) we have

$-9(x-5)=x+22\frac{1}{2}$

solve for x

remember that

$22\frac{1}{2}=\frac{45}{2}$

$-9x+45=x+\frac{45}{2}$

$x+9x=45-\frac{45}{2}$

$10x=\frac{45}{2}$

Look for parenthesis and apply the distributive property; combine like terms; move your variable terms to one side and constants to the other side of the equal sign; go in reverse PEMorDAorS to isolate the variable using inverse operations

Part 16)

Let

n------> the number

we know that

4n-5=2n+3 -----> algebraic expression that represent the situation

solve for n

4n-2n=3+5

2n=8

n=4

Part 17) we have

14 - 2(3p + 1) = 6(4 + p)

14 - 6p-2 = 24+6p ------> distribute the to the and ; distribute the to the and

Part 20) we have

14 - 2(3p + 1) = 6(4 + p)

step 1

distribute the to the and ; distribute the to the and

14 - 6p-2 = 24+6p

step 2

Group terms that contain the same variable and move the constant to the other side

6p+6p=14-2-24

step 3

Combine like terms

12p=-12

step 4

Divide by both sides

p=-1
