For the left triangle you do 5x4 divided by 2 and you get 10
For the middle you do 5x7 divided by 2 and you get 17.5
For the right triangle you do 5x2 divided by 2 and you get 5
Add those together and you have 32.5 which is the area

Answer:

area = 50 cm²

Step-by-step explanation:

To calculate area of the composite figure, divide it into simple shapes (triangles, rectangles, squares...), calculate the area of each shape and add them together.

We can divide the figure into the triangle in the left, rectangle in the middle and another triangle in the right.

Formulas

<u>Area of triangle</u>

A = \frac{1}{2}bh

A ... area of triangle

b ... base

h ... height perpendicular to the base

<u>Area of rectangle</u>

A = length \times width

A ... area of rectangle

Step 1: Calculate areas of simpler shapes.

Area of left triangle:

A = \frac{1}{2}bh

A_{\text{left}\triangle} = \frac{1}{2} \times 5 \text{ cm} \times 4 \text{ cm}

A_{\text{left}\triangle} = 10 \text{ cm}^2

Area of rectangle:

A = length \times width

A_{\text{rectangle}} = 7 \text{ cm} \times 5 \text{ cm}

A_{\text{rectangle}} = 35 \text{ cm}^2

Area of right triangle:

A = \frac{1}{2}bh

A_{\text{right}\triangle} = \frac{1}{2} \times 2 \text{ cm} \times 5 \text{ cm}

A_{\text{right}\triangle} =5 \text{ cm}^2

Step 2: Add the areas together.

A = A_{\text{left}\triangle} + A_{\text{rectangle}} + A_{\text{right}\triangle}

A = 10 \text{ cm}^2 + 35 \text{ cm}^2 + 5 \text{ cm}^2

A = 50 \text{ cm}^2

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test
SSSSS [86.1K]

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."

<h3>What is F-statistics?</h3>

An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.

Some key features regarding the F-statistics are-

  • It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
  • When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
  • A significant result does not imply that all of your variables have been significant.
  • The statistic is simply comparing the cumulative influence of all the variables.

Find the missing value of x and y.
scoray [572]

Step-by-step explanation:

tan 60 = 21 ÷ y

1.73 = 21 ÷ y

y = 21 ÷ 1.73

y = 12.14

tan 30 = x÷ 12

0.6 x 12 = x

x = 7.2
