Answer:

x=16

Step-by-step explanation:

Because of Thales Intercept Theorem, AN/NG=NE/GL

NE/GL=1/2, AG=2x-9+x+7=3x-2

2x-9/3x-2=1/2

x=16

What is the area of the grey matting in this 16” by 20” picture frame if the picture to be framed is 11” x 14”?

rusak2 [61]

Find the area [ a = bh ] of both then subtract.

16 * 20 = 320

11 * 14 = 154

320 - 154 = 166"

Best of Luck!

A ribbon is 12 3/8.Into how many 3/4 peices can it be cut?

lozanna [386]

namely how many times does 3/4 go into 12⅜?

let's firstly convert the mixed fraction to improper fraction, and then divide.

$\bf \stackrel{mixed}{12\frac{3}{8}}\implies \cfrac{12\cdot 8+3}{8}\stackrel{improper}{\cfrac{99}{8}} \\\\\\ \cfrac{99}{8}\div \cfrac{3}{4}\implies \cfrac{99}{8}\cdot \cfrac{4}{3}\implies \cfrac{99}{3}\cdot \cfrac{4}{8}\implies 33\cdot \cfrac{1}{2}\implies \cfrac{33}{2}\implies 16\frac{1}{2}$

A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal

juin [17]

Answer: $H_0:p\leq0.72$

$H_a:p\neq0.72$

Step-by-step explanation:

Given : A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72% .

Let 'p' be the new proportion of high school seniors who felt that "getting rich" was an important personal goal .

Claim : $p\neq0.72$

We know that the null hypothesis has equal sign.

Therefore , the null hypothesis for the given situation will be opposite to the given claim will be :-

$H_0:p=0.72$

And the alternative hypothesis must be :-

$H_a:p\neq0.72$

Hence, the null hypothesis and the alternative hypothesis that we would use for this test :

$H_0:p\leq0.72$

$H_a:p\neq0.72$
