Is the figure a polygon? Is it convex or concave?

Answers

Answer 1

Answer:

This figure is not polygon and it is a concave

Step-by-step explanation:

A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons - a polygon, by definition, is made up of straight lines.

And a convex is like a circle. But a concave having an outline or surface that curves inward like the interior of a circle or sphere.

Find LA, AE, SL

Answers

AE= 6.93 - 4.63 = 2.3 cm

LA: a2 + b2 = c2
(3.26)2 + (2.3)2 = LA2
10.63 + 5.29 = LA2
15.92 = LA2
sqrt 15.92 = LA
So, LA= 3.98 cm

LS: a2 + b2 = c2
(3.98)2 + (b)2 = (6.93)2
b = sqrt (6.93)2 - (3.98)2
So, LS = 5.67 cm

Two dice, a red and a blue, are rolled. Find the probability that both dice show sixes

Answers

Answer:

2.78%

Step-by-step explanation:

So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.

Create a histogram of this data.

To create a histogram, hover over each age range on the x-axis. Then click and drag up to plot the data.

Answers

Answer:

Refer to image

Step-by-step explanation:

When creating a histogram it is best to create a range for the different variables that are available.

So for the sake of covering all the possible ranges from 1 - 22, let's divide it into 5 categories.

0 - 5

6 - 10

11 - 15

16 - 20

21 - 25

Now that we have set ranges for the different variables, we then find the frequencies.

0 - 5 : 3

6 - 10 : 2

11 - 15 : 3

16 - 20 : 1

21 - 25 : 3

Now that we have all the values we can then create our histogram

The answer is D

For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.

x= 8

Step-by-step explanation:

Half of a circle or a straight line is equal an angle of 180 degrees. Therefore, both the measurements of angles RPS and QPR are equal to 180 degrees.

3x + 12 + 7x + 88 = 180

Add like terms

10x + 100 = 180

-100. -100

10x = 80

/10. /10

x = 8

I believe it is 8
The angles combined should be 180
So, 180= 10x +100
Subtract 100 from both sides to cancel it out
80= 10x
Divide by 10 on both sides
8 = X

Answers

Answer:

Step-by-step explanation:

P(A U B) = P (A) + P (B) - P (A and B)

= 0.64 + 0.4 - 0.356

= 0.684

The value of P(A∪B) is 0.684

What is probability?

Probabilities are used to determine the chances of events

The given parameters are:

P(A)=0.64,

P(B)=0.4

P(A∩B)=0.356

To find the value of P(A∪B), we make use of the following formula

P(A∪B) = P(A) + P(B) - P(A∩B)

So, we have:

P(A∪B) = 0.64 + 0.4 - 0.356

Evaluate the expression

P(A∪B) = 0.684

Hence, the value of P(A∪B) is 0.684
