Answer:

9x - 45

Step-by-step explanation:

To simplify this expression, we need to use Distributive Property to get rid of the parentheses. So, we multiply the -9 by everything inside the parentheses.

-9(-x + 5)

-9 · -x = 9x

-9 · 5 = -45

Now we add our products together.

9x + -45

Since there is a '+' sign and a '-' sign next to each other, we can simplify it to just a '-'.

9x - 45

Hope this helped! Let me know if you have any other questions! :)

What is the measure of one of the interior angles of the regular quadrilateral?

creativ13 [48]

Answer:

Measure of one of the interior angles ⇒ 90°

Step-by-step explanation:

If we are considering a regular polygon, all sides are ≅, respectively all angles are ≅ as well;

Now any quadrilateral has total interior angle measure of 360 degrees, provided they each can be split into two triangles and hence knowing a triangle is 180 degrees each, ⇒ 180 * 2 = 360°;

So if all these angles are ≅, we can claim that;

m∠ 1 = m∠ 2 = x = m∠ 3 = m∠ 4, where ∠1, 2, 3, and 4 are interior angles

x + x + x + x = 360 degrees ( ° ),

4x = 360°,

x = 90° = m∠ 1 = m∠ 2 = m∠ 3 = m∠ 4,

Solution; Measure of one of the interior angles⇒ 90°

Let x denote the courtship time for a randomly selected female–male pair of mating scorpion flies (time from the beginning of in

gavmur [86]

Complete Question:

a) Is it plausible that X is normally distributed?

b) For a random sample of 50 such pairs, what is the (approximate) probability that the sample mean courtship time is between 100 min and 125 min?

Answer:

a) It is plausible that X is normally distributed

b) probability that the sample mean courtship time is between 100 min and 125 min is 0.5269

Step-by-step explanation:

a)X denotes the courtship time for the scorpion flies which indicates that is a real - valued random variable, and since normal distribution is a continuous probability distribution for a real valued random variable, it is plausible that X is normally distributed.

b) Probability that the sample mean courtship time is between 100 min and 125 min
