_30. Solve the following logarithmic equation: log8(x + 9) + 3 = 3

Mathematics
1 answer:
Bezzdna [24]2 years ago
7 0

Answer:

A

Step-by-step explanation:

using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

log_{8} (x + 9) + 3 = 3 ( subtract 3 from both sides )

log_{8} (x + 9) = 0 , then

x + 9 = 8^{0} = 1 ( subtract 9 from both sides )

x = - 8

Which of the following is NOT a principle of making inferences from dependent​ samples? Choose the correct answer below. A. The
Serga [27]

Answer:

D. Testing the null hypothesis that the mean difference equals 0 is not equivalent to determining whether the confidence interval includes 0

Step-by-step explanation:

Dependent samples are samples that are related to one another.

In a hypothesis test, the hypothesis test and the confidence interval are equivalent in the sense that they result in the same conclusion.

However, in an hypothesis test , we fail to reject the null hypothesis if the rejection region is greater than the t-test statistics. It is therefore crucial to understand that if the true mean is zero. the confidence interval level for the mean of differences within the lower limit and the upper limits must contain zero , which implies the mean difference and the confidence interval  are equivalent.

A 28 foot ladder is propped against a wall. The base of the ladder is 19 ft from the wall how far up the wall does the ladder go
docker41 [41]

Answer:

20.6

Step-by-step explanation:

The problem can be solved by applyPythagoreanean theory

a^2+b^2= c^2

19^2 + b^2= 28^2

361 + b^2= 784

b^2= 784-361

= 423

b= √423

= 20.6

In “modeling with linear equations” how do i solve<br><br> -11-8x=-3x+19
user100 [1]

Answer:

x = -6

Step-by-step explanation:

-11 - 8x = -3x + 19 (Move constants to right side)

-8x = -3x + 19 + 11 (Move x to left side)

3x - 8x = 30 (simplify)

-5x = 30 (divide both sides by -5)

x = -6
