Answer:

x° = 125°

(x+10)° = 135°

Step-by-step explanation:

<u>Given:</u>

Sum of measures of angle = 720°

<u>Solution:</u>

We know that:

Sum of measures of angle = 720°

120 + 100 + 120 + x + 10 + 120 + x = 720

x + x + 120 + 100 + 120 + 10 + 120 = 720

2x + 470 = 720

2x = 720 - 470

2x = 250

Divide both sides by 2

x = 250/2

x = 125

Now,

<u>Angles measures</u>

x° = 125°

(x+10)° = (125+10)° = 135°

$\rule[225]{225}{2}$

Hope this helped!

Answer:

120+100+120+120+x+x+10=720 (given)

470+2x=720

2x=720-470

x=250/2

x=125

Answer:

<em> 85% level of the confidence interval is</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given the size of the sample 'n' = 295

Mean of the sample x⁻ = 26.5

The Standard deviation of the Population = 2.7

85% level of the confidence interval is determined by

$(x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })$

Critical value Z₀.₁₅ = 1.036

<em> 85% level of the confidence interval is determined by</em>

$(x^{-} - Z_{0.15} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.15} \frac{S.D}{\sqrt{n} })$

$(26.9 -1.036 \frac{2.7}{\sqrt{295} } , 26.5 + 1.036 \frac{2.7}{\sqrt{295} })$

( 26.5 - 0.1628 , 26.5+0.1628)

(26.3372,26.6628)
