Solve the following proportion for v. <br>8/5 = v/6 <br>Round your answer to the nearest tenth.

bekas [8.4K]

Answer:

$v=\frac{48}{5}=9\frac{3}{5} \\$

Step-by-step explanation:

$\frac{8}{5}=\frac{v}{6}$

Swap sides:

$\frac{v}{6}=\frac{8}{5}$

Multiply to both sides by 6:

$\frac{v}{6}\cdot6=\frac{8}{5}\cdot6$

Group like terms:

$\frac{1}{6}\cdot6v=\frac{8}{5}\cdot6$

Simplify the fraction:

$v=\frac{8}{5}\cdot6$

Multiply the fractions

$v=\frac{8\cdot6}{5}$

Simplify the arithmetic:

$v=\frac{48}{5}$

A? 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense he

masya89 [10]

Answer:

The correct option is option c.

H0: p not equal to 0.5

H1: p equal to 0.5

Step-by-step explanation:

1. H0: p not equal to 0.5

H1: p equal to 0.5

2. P cap = 104/ 260

P cap = 0.4. ( where p cap is the sample proportion)

3. Find the test statistic

Using : Z = ( p cap - p) /√ [(p ×q)/n] where p = 0.5 q= 1-p = 0.5. n=260

Z = -3.23

4. P value = 0.006

5. Since p value is less than the alpha level (0.01) . we reject the null hypothesis and conclude that the touch therapists are not effective.
