-400=-6(8 - 8x) - 4x

Mathematics

4 0

<u>Answer: </u>

The solution of -400 = -6(8 - 8x) - 4x is -8

<u>Solution: </u>

From question, the equation given is,

-400 = -6(8 - 8x) - 4x

Multiplying the terms inside the bracket with -6

-400 = -48 + 48x - 4x

On solving,

-400 = -48 + 44x

In the above equation, move -48 from right side to left side,

-400 + 48 = 44x

Now,

-352 = 44x

44x = -352

Now, the ‘x’ becomes,

x = \frac{-352}{44}

Thus, the value of the variable ‘x’ is:

x = -8

lukranit [14]
If 24 students went on a field trip, and 24 students represented eight tenths of the class, then 24 =  \frac{8}{10}x.
First, multiply by 10 on both sides.
240 = 8x
Divide by 8 on both sides.
x = 30.

The class has 30 students in all.
This is, however, only the equation way to solve.

Alex777 [14]

Complete question :

A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.

Construct a confidence interval for the mean jump height of gray kangaroos.

Answer:

(271, 301)

Step-by-step explanation:

Given that:

Mean (x¯) = 286

Margin of Error = 15 inches

The confidence interval :

(Mean - Margin of Error), (mean + margin of error)

(286 - 15), (286 + 15)

(271, 301)

Hence confidence interval equals : (271, 301)
