What is the area of this compound shape? I need a step-by-step answer.

Answer:

63.5, 66.5

Step-by-step explanation:

Approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

The empirical rule states that for a normal distribution, approximately 68% of the data lies within one standard deviation of the mean, approximately 95% of the data lies within two standard deviations of the mean, and approximately 99.7% of the data lies within three standard deviations of the mean.

Since we want to find the interval that represents the middle 68% of Camden's finishing times, we need to find the range of times that are one standard deviation above and below the mean.

The mean of Camden's finishing times is 65 seconds, and the standard deviation is 1.5 seconds, so the interval that represents the middle 68% of his finishing times is:

[65 - 1.5, 65 + 1.5] = [63.5, 66.5] seconds

This means that approximately 68% of Camden's finishing times fall within the interval from 63.5 seconds to 66.5 seconds.

Given:

There are 3 cards, a 5 a 6 and a 7.

You pick a card at random. Without putting the first card back, you pick a second card at random.

To find:

The probability of picking a 5 and then picking a 6.

Solution:

We have,

Total number of cards = 3

Number of card of 5 = 1

So, probability of getting a card of 5 is:

[tex]P(5)=\dfrac{\text{Number of card of 5}}{\text{Total number of cards}}[/tex]

[tex]P(5)=\dfrac{1}{3}[/tex]

After this selection, the remaining number of cards is 2. So, probability of getting a card of 6 in second draw is:

[tex]P(6)=\dfrac{\text{Number of card of 6}}{\text{Total number of remaining cards}}[/tex]

[tex]P(6)=\dfrac{1}{2}[/tex]

Now, the probability of picking a 5 and then picking a 6 is

[tex]P(\text{5 then 6})=P(5)\times P(6)[/tex]

[tex]P(\text{5 then 6})=\dfrac{1}{3}\times \dfrac{1}{2}[/tex]

[tex]P(\text{5 then 6})=\dfrac{1}{6}[/tex]

Therefore, the probability of picking a 5 and then picking a 6 is [tex]\dfrac{1}{6}[/tex].

Answer:

B ; C ; D

Step-by-step explanation:

Number of faces on a number cube = 6

Sample space = (1, 2, 3, 4, 5, 6)

P(1 then 0)

P(1) = 1/6 ; P(0) = 0

P(1 then 0) = 1/6 * 0 = 0

P(even number then odd number) :

P(even number) = 3/6 = 1/2

P(odd) = 3/6 = 1/2

P(even number then odd number) = 1/2 * 1/2 = 1/4

P(6 then 2) :

P(6) = 1/6 ; P(2) = 1/6 = 1/2

P(6 then 2) = 1/6 * 1/6 = 1/36

P(even number then 5) :

P(even) = 3/6 = 1/2

P(5) = 1/6

P(even number then 5) = 1/2 * 1/6 = 1/12

P(odd number then 2) :

P(odd) = 3/6 = 1/2

P(2) = 1/6

P(odd number then 2) = 1/2 * 1/6 = 1/12

I will put the method in the comments

how to find the P: To find the p of Any Shape  is the same formula,  adding all the sides up. So to find the p of this shape all you need to do is add all the sides up. 3+12.5+7.5+13. Add these up and you get the P

Answer:

72degrees

Step-by-step explanation:

triangle=180

C:90 B:18

180-90-18=72

Answer:

Step-by-step explanation:

132 degrees

Split this figure out. Find the area of the square, as well as the rectangle.

First, the square

A= 4 x 3

A= 12 ft^2

Therefore, the square has an area of 12ft^2.

Then, the rectangle.

We must first find the length of the unknown side.

We have two measurements of 3ft on each side, as well as the middle measurement of 4ft.

So,

3+3+4=10

Now, find the area.

A= 2 x 10

A=20ft^2

Add the areas.

20+12=32ft^2

Therefore, the area of the figure is 32ft^2.

I hope this is correct. Best of luck.

Answer:

c us the correct answer for this question

Answer:

x = 1, y = 3

Step-by-step explanation:

Given:

x - y = -2

2x + y = 5

First, add y on both sides for the first equation.

x = y - 2

Then, plug in x into the second equation.

2(y -2) + y = 5

2y - 4 + y = 5

3y = 9

y = 3.

Next, now that you've found y, plug it into either the first or second equation to solve for x. I'll be using the second equation.

2x + 3 = 5

2x = 2

x = 1.

Ans: x = 1, y = 3

Answer:

I believe it is D

Step-by-step explanation:

We can first multiply the 2 and 4 together to get 8.

Wow we already eliminated A.

When you have negative powers, you can just replace it with their inverse and turn the power positive.

For example, 2 to the power of -3  (2 ^ -3) can be replaced by 1/2 to the power of 3 (1/2^-3).

So we now have 8  (x^4 / yx^2

We can then just subtract the x's power of 2, because when dividing exponents with the same variable or base, we can just subtract them.

For example, x^5  divided by x ^ 2 has the same base/ variable of x, and you can subtract the 5 by 2 to get x^3.

So we have 8 ( x^2y)

So 8x^2 y

Answer:

Step-by-step explanation:

Answer:

y = 8x + 25

Step-by-step explanation:

Using the coordinates (10, 105) and (20, 185)

The standard linear equation is expressed as y = mx+c

m is the slope

c is the intercept

m = 185 - 105/20-10

m = 80/10

m = 8

Get the y-intercept

Since y = mx+c

105 = 8(10) + c

105 = 80 + c

c = 105 - 80

c = 25

Get the required equation

Recall that y = mx+c

y = 8x + 25

Hence the required equation is y = 8x + 25
