<1+<2=90°

The sum of measures of angles A and B is 90°

Hence the angles are complementary

As complementary angles have sum 90°

Step-by-step explanation:

$\frac{5}{2} = \frac{x - 4}{3}$

$3 \times \frac{5}{2} = \frac{x - 4}{3}$

$\frac{3}{1} \times \frac{5}{2} = \frac{x - 4}{3}$

cross multiplication

$\frac{6 \times 5}{2} = \frac{x - 4}{3}$

$15 = \frac{x - 4}{3}$

$15 \times 3 = x - 4$

$45 + 4 = x$

$49 = x$

Find the area of this trapezoid. Area = _______ square units. Round to the nearest whole number.

fredd [130]

Answer:

119 square units

Step-by-step explanation:

To find the area of a trapezoid, use this formula: (a+b)/2 * h

Substitute 24, 10, and 7 for a, b, and h, respectively.

((24 + 10)/2) * 7

Step 1: Add 24 and 10 to get 34.

(34/2) * 7

Step 2: Divide 34 by 2 to get 17.

17 * 7

Step 3: Multiply 17 by 7 to get 119

119

The area of this trapezoid is 119 square units.

Use the equation below to find T, if w=85, m= 12, and a=3. T=w-ma T = 3,060 X ?

saw5 [17]

Answer:

T = 49

Step-by-step explanation:

T = w - ma

w = 85

m = 12

a = 3

Plug in the corresponding numbers to the corresponding variables:

T = (85) - (12) * (3)

Remember to follow PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

First, multiply, then subtract:

T = 85 - (12 * 3)

T = 85 - 36

T = 49

T = 49 is your answer.

What will be the value of median of a moderately asymmetrical distribution? If the mean and mode are 30 and 24 respectively.

sineoko [7]

The mean, the median and the mode are measures of central tendency, and they are related in some many ways, depending on the type of distribution.

The median of the moderately asymmetrical distribution is 26

The given parameters are:

$Mean = 30$

$Mode = 24$

For a moderately asymmetrical distribution, the mean, median and mode are related by the following equation:

$Mode = 3 * Median - 2 * Mean$

Substitute known values

$30= 3 * Median - 2 * 24$

$30= 3 * Median - 48$

Collect like terms

$3 * Median =30+ 48$

$3 * Median =78$

Divide both sides by 3

$Median =26$
