Answer:

x = 17deg

Step-by-step explanation:

Let angle y be the unknown angle IN THE TRIANGLE.

Angle y = 180 - 90 - 73

= 17deg

Angle x = Angle y (Alternate angles on 2 parallel lines)

Use multiplication in the distributive property to find the quotient 252 divided by 9

ira [324]

252 divided by 9 is 28

Firstly, I muplity 20 and 9.

I have 180.

Then I also muplity 8 and 9.

I got 72.

Then I add 72 and 180 which got me 252.

(I hope this helped!)

20.

Alik [6]

Answer:

After 3 seconds

Step-by-step explanation:

Given

$h(t) = -16t^2 + 96t$

Required

Seconds to attain maximum height

The maximum of a quadratic function $y = ax^2 + bx + c$ is calculated using:

$x = -\frac{b}{2a}$

So, we have:

$t = -\frac{b}{2a}$

Where:

$a = -16$ and $b = 96$

So:

$t = -\frac{96}{2 * -16}$

$t = -\frac{96}{-32}$

Cancel out negatives

$t = \frac{96}{32}$

$t = 3$

An instructor who taught two sections of engineering statistics last term, the first with 20 students and the second with 30, de

Lelechka [254]

Answer:

(a) $P(X=10) = 0.2070$

(b) $P(X\geq 10) = 0.3798$

Step-by-step explanation:

Note that in this problem we have an initial population N = 50, of which 30 fulfill a certain characteristic "m" (belong to the second section). Then, from the population N, a sample of size n = 15 is selected and it is desired to know how many comply with the desired characteristic (second section).

Let X be the number of projects in the second section, then X is a discrete random variable that can be modeled by a hypergeometric distribution.

(a)

Therefore, to answer question (a) we use the following equation presented in the attached image:

Where:

$N = 50\\m = 30\\n = 15\\X = 10$
