Answer:

Area = 390 square cm

Step-by-step explanation:

Area = Area of rectangle + Area of triangle

$= (length \times breadth ) + ( \frac{1}{2} \times base \times height ) \\\\=( 20 \times 15 ) + (\frac{1}{2} \times 15 \times 12) \\\\= 300 + 90 \\\\= 390 \ cm^2$

Identify the expression for calculating the mean of a binomial distribution

TEA [102]

Option C: np is the expression used for calculating the mean of a binomial distribution.

Explanation:

From the options, we need to determine the expression that is used for calculating the mean of a binomial distribution.

Option A: npq

The variance of the binomial distribution can be calculated using the expression npq.

Hence, Option A is not the correct answer.

Option B: $\sqrt{npq}$

The standard deviation of the binomial distribution can be calculated using the expression $\sqrt{npq}$

Hence, Option B is not the correct answer.

Option C: np

The mean of the binomial distribution can be calculated using the expression np

Hence, Option C is the correct answer.

Option D: $\sum\left[x^{2} \cdot P(x)\right]-\mu^{2}$

The mean of the binomial distribution cannot be determined using the expression $\sum\left[x^{2} \cdot P(x)\right]-\mu^{2}$

Hence, Option D is not the correct answer.

Two angles are supplementary. One angle is twenty less than four times the other angle. Find the measure of the larger angle.

Cloud [144]

If two angles are supplementary, then they add up to 180.

Angle 1 = twenty less than four times the other angle

Angle 2 = the other angle

Angle 2 = 1x

Angle 1 = 4x - 20

Next, we can add up angles 1 and 2 and set the sum equal to 180.

x + 4x - 20 = 180

5x - 20 = 180

5x = 200

x = 40

Now that we know x, we can find the values of our angles.

Angle 1 = 4(40) - 20 = 160 - 20 = 140 degrees

Angle 2 = 40 degrees

Hope this helps!! :)
