Answer 1

From the figure, we can notice that : Surface area of the pyramid is equal to Sum of the area of the square and Sum of the areas of 4 triangles.

We know that : Area of a square is given by : Side x Side

Given : Side of the square = 3 cm

⇒ Area of the square = 3 x 3 = 9 cm²

We know that : Area of the triangle = 1/2 x Base x Height

From the figure, We can notice that, Base of each triangle = 3 cm and height of the each triangle = 3 cm

⇒ Area of one triangle = 1/2 × 3 × 3 = 4.5 cm²

Surface area of the pyramid = Surface of the square + Surface area of the 4 triangles

⇒ Surface area of the pyramid = 9 cm² + 4(4.5) cm²

⇒ Surface area of the pyramid = 9 cm² + 18 cm² = 27 cm²

Answer : Surface area of the pyramid = 27 cm²

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

Given P(A)=0.64P(A)=0.64, P(B)=0.4P(B)=0.4 and P(A\cap B)=0.356P(A∩B)=0.356, find the value of P(A\cup B)P(A∪B), rounding to the nearest thousandth, if necessary.

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

Find the length of all segments in the triangle
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

Submit Answer

Answers

Answer:

You save $266. The television costs $2394.

Step-by-step explanation:

10% off the original price is $266. The television is 10% off, meaning the new price is 90% of the original price. Therefore, you can subtract $2660 - $266 or multiply 90% × $2660.
