Answer:

x = 2

Step-by-step explanation:

0.2x + 0.3 = 0.1x + 0.5 ( subtract 0.1x from both sides )

0.1x + 0.3 = 0.5 ( subtract 0.3 from both sides )

0.1x = 0.2 ( divide both sides by 0.1 )

x = 2

An instructor of a biology class believes the average final exam score for his biology class was more than 75. Suppose a sample

likoan [24]

Answer:

The value for the test statistics = 3.48

Step-by-step explanation:

Given that:

population mean $\mu$ = 75

sample size n = 25

sample mean $\overline x$ = 78.48

standard deviation = 5

The value for the test statistics can be computed by using the formula:

$z = \dfrac{\overline x- \mu}{\dfrac{\sigma}{\sqrt{n}}}$

$z = \dfrac{78.48- 75}{\dfrac{5}{\sqrt{25}}}$

$z = \dfrac{3.48}{\dfrac{5}{5}}$

z = 3.48

The value for the test statistics = 3.48

The greatest common factor of 42 & 15

Readme [11.4K]

42 : 2 = 21

21 : 3 = 7

7 : 7 = 1

42 = 2 · 3 · 7

15 : 3 = 5

5 : 5 = 1

15 = 3 · 5

GCF(42, 15) = 3
