Answer:

$\displaystyle 55° = x$

Step-by-step explanation:

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

180° = (2x + 15)° + x°

180° = 15° + [3x]°

- 15° - 15°

____________

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

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:

$(x + 5) ^ 2 = 40$

Suppose the number of dropped footballs for a wide receiver over the course of a season are normally distributed with a mean of

snow_lady [41]

Answer:

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

Z = - 1.5

Step-by-step explanation:

Explanation:-

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

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

$Z = \frac{x-mean}{S.D}$

$Z = \frac{13 -16}{2} = \frac{-3}{2} = -1.5$

Final answer:-

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

Z = - 1.5
