Answer:

The solution to the equation is x = [log(2048)/log(23)] - 5

Step-by-step explanation:

Hi there!

First, let´s write the equation:

5 ⋅ 23^(x+5) = 10240

To solve for x, divide both sides of the equation by 5

23^(x+5) = 2048

Apply log to both sides of the equation

log(23^(x+5)) = log(2048)

Apply logarithm property: log(xᵃ) = a log(x)

(x + 5) log(23) = log(2048)

divide both sides of the equation by log(23)

x + 5 = log(2048)/log(23)

subtract 5 to both sides of the equation

x = [log(2048)/log(23)] - 5

The solution to the equation is x = [log(2048)/log(23)] - 5

Event A Answer: $\frac{5}{12}$

<u>Step-by-step explanation:</u>

sum greater than 7 leaves are the following combinations for 8, 9, 10, 11, and 12:

8 = 26, 35, 44, 51, 62 (5 possibilities)

9 = 36, 45, 54, 63 (4 possibilities)

10 = 46, 55, 64 (3 possibilities)

11 = 56, 65 (2 possibilities)

12 = 66 (1 possibility)

This is a total of 15 possibilities out of 36 total: $\frac{15}{36}$ = $\frac{5}{12}$

***********************************************************************************

Event B Answer: $\frac{1}{2}$

<u>Step-by-step explanation:</u>

sum is an even number means both dice are odd or both dice are even. That results in the following combinations:

11 13 15

22 24 26

31 33 35

42 44 46

51 53 55

62 64 66

This is a total of 18 possibilities out of 36 total: $\frac{18}{36}$ = $\frac{1}{2}$

The supplement of an angle is equal to 2 times the angle

Vilka [71]

Well if it is a supplement then that means that is has to equal 180 degrees. If one angle is two times the other and it equals to 180 you can make an equation out of this.
First you would do:
x+2x=180

Then
3x=180

Last
x=60

Therefore x will equal 60 degrees which means that angle 1 is 60 and angle 2 is 120

I will mark brainleist if right answer

8_murik_8 [283]

Answer:

-16,-6,4,14,24

Step-by-step explanation:

First thing first, we need to alter this equation is y is the value we are fining. we can do this by adding 10x to both sides. our new equation is

y=10x+4

Now, all we have to do is plug in out x values in order to get our y values and complete the table.

Example, 10x2 is 20 and 20+4 is 24 so when x is 2, y is 24

What price do farmers get for the peach crops? in the third week of June, a random sample of 40 farming regions gave a sample me

prohojiy [21]

Given:
Sample size, n = 40
Sample mean, xb = $6.88
Population std. deviation, σ = $1.92 (known)
Confidence interval = 90%

Assume normal distribution for the population.
The confidence interval is
(xb + 1.645*(σ/√n), xb - 1.645*(σ/√n)
= (6.88 + (1.645*1.92)/√40, 6.88 - (1.645*1.92)/√40)
= (7.38, 6.38)

Answer: The 90% confidence interval is (7.38, 6.38)
