Log3(2x-1)=3 help me out:(

Mathematics
1 answer:
aleksley [76]2 years ago
5 0

Answer:

x = 2.

Step-by-step explanation:

(Brainliest?)

So log3(2x-1)+log3(x+7)=3 = log3(3^3) So (2x- 1)(x+7) = 27..... 2x^2+13x - 34 =0 (2x+17)(x - 2) = 0 ..so x = 2 or - 17/2. The solution x = - 17/2 is rejected since we cannot have log 3(2*- 17/2 - 1),a negative number. So the answer is x = 2.

George has a square sandbox in the backyard. The sandbox has an area of 160 square feet. To the nearest foot, what is the length
spin [16.1K]

We know that the sandbox is square, and that the area is 160 sq ft. Since A = s^2 for a square, let's work backwards and find s if A = 160 sq ft = s^2.

s^2 = 160 = 16(10). We do this because 16 is the largest perfect square factor of 160.

Then the length of one side of the square is approx. s = 4√10 ft (12.65 ft)

One condition for performing a hypothesis test is that the observations are independent. Marta is going to take a sample from a
AleksandrR [38]

Answer:

The correct answer to the following question will be "60 students".

Step-by-step explanation:

Marta will be taking a sampling frame from some kind of 600 student group.

Mean,

N = 60  

Although the sampling method could perhaps consist of the following components 10% of the population,

⇒  600\times 10 \ percent

⇒  60

In order to view these findings as autonomous, 60 students would then have to analyze Marta lacking replacements.
