<em>Answer:</em>

<em>Step-by-step explanation:</em>

The fastest and simplest way I got it is this...

There are 9 small squares that make up one big square, right?

The 5 out of 9 squares are shaded.

The area of the whole square is 144 (12 times 12).

The logical thing to do is figure out what's 5/9 (five-ninths) of 144.

$12*12=144\\\frac{5}{9}*144=80$

So I believe the answer is 80.

Hope that helped! Tell me if it did, I don't want to mislead people. (So can I have brainliest?)

Triangle abc is an isosceles right triangle. What is the measure of one base angle? 30ş 45ş 60ş 90ş.

alisha [4.7K]

Answer:

45°

Step-by-step explanation:

The acute angles of a right triangle are complementary. The base angles of an isosceles triangle are congruent. If x is the measure of the base angles, this requires ...

x = 90-x . . . . . the base angle is congruent to the other base angle

2x = 90 . . . . . add x

x = 90/2 = 45 . . . . divide by 2

The measure of a base angle of an isosceles right triangle is 45°.

It can be useful to remember this fact.

Situation D: Suppose that, in a one-minute period during an electrical storm, the number of lightning strikes on a radar antenna

Crank

Answer:

21.77% probability that the antenna will be struck exactly once during this time period.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

In this question:

$\mu = 2.40$

Find the probability that the antenna will be struck exactly once during this time period.

This is P(X = 1).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 1) = \frac{e^{-2.40}*2.40^{1}}{(1)!} = 0.2177$

21.77% probability that the antenna will be struck exactly once during this time period.
