Cora takes a sheet of paper and cuts from one corner to the opposite corner, making two triangles. If the piece of paper is 15 i

Bogdan [553]

Answer: 17 inches

Explanation: so we have a triangle with the two side lengths 8 and 15 and we’re trying to find the hypotenuse. so using the pythagorean theorem, we have 8^2 + 15^2 = c^2. when we solve we get 64 + 225 = c^2, which is 289 = c^2. next, we find the square root of both sides and c = 17 inches.

hope this helped!

Solve for x to the nearest tenth

tensa zangetsu [6.8K]

Answer:

Using the pythagoras theorem

Let's say the hypotenuse of the first diagram is b

b²=4²+2²

b²=16+4

b²=20

b=✔(20)

In finding x , b will be the opposite and the x be the hypotenuse

x²=(✔20)²+7²

x²=20 +49

x²=69

x=8.31

Solve the problem. For a standard normal distribution, find the percentage of data that are between 3 standard deviations below

solong [7]

Answer:

83.85%

Step-by-step explanation:

We will use the empirical rule. For a standard normal distribution the mean is equal to 0 and the standard deviation is equal to 1. Then, between 3 standard deviations below the mean, we have 2.35% + 13.5% + 34% = 49.85% of data, and 1 standard deviation above the mean we have 34% of data. Therefore, the percentage of data that are between 3 standard deviations below the mean and 1 standard deviation above the mean is 49.85%+34% = 83.85%.
