iVinArrow [24]3 years ago
4 0

Answer:

\displaystyle 55° = x

Step-by-step explanation:

Angles <em>B</em><em> </em>and<em> </em><em>C</em><em> </em>form a straight angle, so you set both expressions equal to 180°:

180° = (2x + 15)° + x°

180° = 15° + [3x]°

- 15° - 15°

____________

\displaystyle \frac{165°}{3°} = \frac{[3x]°}{3°} \\ \\ 55° = x

I am joyous to assist you anytime.

What equation results from completing the squre and then factoring x^2+10=15
nlexa [21]

For this case we must complete squares:

x ^ 2 + 10x = 15

We add the square of half the coefficient of the term "x",

(\frac {b} {2a}) ^ 2 on both sides of the equation:

x^2+10x+(\frac {10} {2 (1)}) ^ 2 = 25 + 15\\x ^ 2 + 10x + 5 ^ 2 = 25 + 15

According to the perfect square trinomial we have:

(a + b) ^ 2 = a ^2 + 2ab + b ^ 2

Rewriting the expression we have:

a = x\\b = 5\\(x + 5) ^ 2 = 25 + 15\\(x + 5) ^ 2 = 40

ANswer:

(x + 5) ^ 2 = 40

snow_lady [41]

Answer:

<em>The z score for a wide receiver who dropped 13 footballs over the course of a season</em>

<em>           Z = - 1.5</em>

Step-by-step explanation:

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

Given Population mean  ' μ'= 16

Standard deviation of Population 'σ' = 2

Let 'x' be the Random Variable of Normal distribution

Given x = 13 foot balls

<em>The z score for a wide receiver who dropped 13 footballs over the course of a season</em>

<em>                 </em>Z = \frac{x-mean}{S.D}<em></em>

<em>                </em>Z = \frac{13 -16}{2} = \frac{-3}{2} = -1.5<em></em>

<u><em>Final answer</em></u><em>:-</em>

<em>The z score for a wide receiver who dropped 13 footballs over the course of a season</em>

<em>           Z = - 1.5</em>
