What is the area of the triangle?
16
8
10

Answers

Answer:

Step-by-step explanation:

Find the area of both triangles inside the bigger triangle and add them together.

Use the Pythagorean theorem to find the missing length of the leg in the smallest triangle:

a² + b² = c²

8² + b² = 10²

64 + b² = 100

36 = b²

6 = b

Calculate the area of the smaller triangle:

1/2(bxh)

1/2(6 x 8)

1/2(48)

Calculate the area of the bigger triangle:

We know that the longer leg is 10 units because we were able to subtract the length of the smaller triangle's leg from 16.

1/2(bxh)

1/2(10 x 8)

1/2(80)

Add both areas to find the area of the largest triangle:

40 + 24 = 64

Step-by-step explanation:

A usability test was conducted to evaluate the design of a store website. The times to complete a certain task were recorded for a sample of 48 users. The sample mean time was 70 seconds with a 95% margin of error of 10 seconds. In other words, researchers estimated with 95% confidence that the mean time to complete the task was between 60 and 80 seconds for all website users. Only one of the following statements is true. Select the correct statement.
1. the probability that the mean time μ will fall between 60 and 80 is 0.95.
2. If many samples are collected from the same population, about 95% of the samples will produce confidence intervals that contain the population mean μ.
3. If a second sample from the same population is selected and a 95% confidence interval is constructed, the new confidence interval will be the same as the 95% C.I. defined in the first study.
4. If the study is repeated, and a new 95% confidence interval is computed, there is 95% chance that the new interval contains the sample mean value >= 40 seconds.

Answers

Answer:

2. If many samples are collected from the same population, about 95% of the samples will produce confidence intervals that contain the population mean μ.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

So the correct option is given by:

Option 2, as we will be 95% sure that the population mean will be in the interval, which can be interpreted that from many samples, about 95% will contain the population mean.

Answers

Answer:

11cm

Step-by-step explanation:

Given data

Volume of cuboid =385 cm^3

Base area= 35cm^2

We know that

Volume = Area* Height

substitute and solve for Height

385=35*H

H= 385/35

H= 11cm

Hence, the height is 11cm

Answer: No, it is not a solution

Step-by-step explanation:

Substitute the value of x as 1 and y as 6

y = x + 6

6 = 1 + 6

6 = 7 (no)

-----------------------------------------

y = 4x + 2

6 = 4(1) + 2

6 = 4 + 2

6 = 6 (Yes)

total number of coins and the other will be the total
value of the coins)
The next step is to solve the problem. Remember to
think of the best method for problem solving

Answers

Answer:

Joel's coin collection had 120 dimes and 80 quarters.

Step-by-step explanation:

Given that Joel had a coin collection of two hundred coins, which were dimes and quarters, and the total value was worth $32, to determine how many coins of each type he had, the following equations must be performed:

0.25 - 0.10 = 0.15

200 x 0.10 = 20

32 - 20 = 12

12 / 0.15 = 80

200 - 80 = 120

(80 x 0.25) + (120 x 0.1) = X

20 + 12 = X

32 = X

Therefore, Joel's coin collection had 120 dimes and 80 quarters.

0.99 is what percent of 9.90?

Answers

Answer:

10%

Step-by-step explanation:

first let's write out the problem

0.99 is what percent of 9.90 = 0.99=9.90*x

We need to what c is so we would do the opposite operation of multiplication, division so we get,

0.99/9.90= .1

now we turn .1 into percent and get out answer

0.1= 10%

Answer:

Step-by-step explanation:

ahh that's like a math tongue twister :P

so just remember that when you are given the final amount, as the 0.99 is, then you want to divide by the total, like this

0.99 / 9.90 =

we don't really need a calculator for this, b/c you can see that the answer will come out to a one, but, where is the decimal, huh

my calculator put the decimal here 0.1

so that's 10% right? which totally makes sense.. right? 0.99 is 10% of 9.90... just move the decimal one place in the 9.9 to get .99 see? so that kinda helps us know where the decimal goes in the answer, if that make sense? The decimal gets moved one place to the LEFT of the one, in our answer when we just did the math in our head.

anyway.. leave a comment if you have more questions :)
