Answer:

Step-by-step explanation:

height = 14tan(24°)

area = 0.5(base)(height)

Find the angle that triples the height.

tanθ = 3×14tan(24°)

θ = arctan(3×14tan(24°)) ≅ 53.2°

Or a very large set of data the measured mean is found to be 288.6 with a standard deviation of 21.2. assuming the data to be no
SashulF [63]

The 68-95-99.7 rule tells us 68% of the probability is between -1 standard deviation and +1 standard deviation from the mean. So we expect 75% corresponds to slightly more than 1 standard deviation.

Usually the unit normal tables don't report the area between -σ and σ but instead a cumulative probability, the area between -∞ and σ. 75% corresponds to 37.5% in each half so a cumulative probability of 50%+37.5%=87.5%. We look that up in the normal table and get σ=1.15.

So we expect 75% of normally distributed data to fall within μ-1.15σ and μ+1.15σ

That's 288.6 - 1.15(21.2) to 288.6 + 1.15(21.2)

Answer: 264.22 to 312.98

9) > cause 1 fl oz is .125 of a cup and multiply that by 96 which is 12 cups which is less than 13 cups
10)> cause 1 lb is 16 oz, multiply 16 by 25 which is 400, which is greater than 384 cups
11) = cause 1 yd is 36 in, so you would multiply 36 in by 8, which is 288 inches, which is the same

Which of the following shows the solution to the inequality
otez555 [7]

Answer:

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:    

1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1

And since -2.5 is less than -1 this statement is true. x does in fact equal 1
