4n(-2)=(5)(-2)
-8n=-10
—— —-
-8 -8

n= 5/4
n= 1 1/4

So the final answer is n= 1.25

Answer:

Follows are the answer to the given point.

Step-by-step explanation:

In point 1:

$\to P( \text{number of response}) = \frac{192}{338} \\$

$= \frac{96}{169}\\\\= 0.56$

In point 2:

$\to P| \text{(Zoloft and fill response)}| = \frac{27}{338}$

$= 0.079$

In point 3:

$\to P(\frac{\text{ full or partial}}{\text{St. John's Wort}}) = \frac{\frac{43}{338}}{\frac{113}{338}}$

$= \frac{43}{338} \times \frac{338} {113}\\\\= \frac{43}{113}\\\\= 0.38$

In point 4:

$\to P(\frac{\text{Placebo}}{\text{full or response}}) = P(\frac{(\text{Placebo} \cap \text{full or response})} {\text{p(full response)}})$

$= \frac{\frac{79}{338}}{ 1- \frac{91}{338}} \\\\ = \frac{\frac{79}{338}}{ \frac{338-91}{338}} \\\\ = \frac{\frac{79}{338}}{\frac{247}{338}} \\\\ = \frac{79}{338} \times \frac {338}{247} \\\\= \frac{79}{274} \\\\ = 0.28$

Talia uses 10 strawberries and 4 oranges to make 8 servings of fruit salad. How many oranges and strawberries does Taila needs t

yarga [219]

Since 12 is 8 x 1 1/2 she needs 1 1/2 time as much fruit.

1 1/2 x 10 = 15 strawberries and 1 1/2 x 4 = 6 oranges.

You could also solve this using proportions:

$\frac{10}{8} = \frac{n}{12}$

Cross multiply and get 8n= 120 divide by 8 and get 15 strawberries

Do the same for the oranges:

$\frac{4}{8} = \frac{n}{12}$

You can see that 4/8 = 1/2 so n/12 has to be 6 to be 1/2 (or solve it using cross products like I did above).

I can't figure out how to solve this

Maslowich

The key: make the base of two side the same,,,
then: for the same base, the exponents are equal.
