Since it's a right triangle you can use the Pythagorean theorem or Trig (Soh Cah Toa).

I'll just use the Pythagorean theorem : a² + b² = c²
a = 9
b = x
c = 18

9² + x² = 18²
81 + x² = 324
x² = 324 - 81
x² = 243
x = √(243)

factor 243 to find a perfect square

x = √(3*81)
x = 9√(3)<u />

The average cost of an IRS Form 1040 tax filing at Thetis Tax Service is $138.00. Assuming a normal distribution, if 77 percent
jek_recluse [69]

Answer:

22.97

Step-by-step explanation:

Given that the average cost of an IRS Form 1040 tax filing at Thetis Tax Service is $138.00.

Let x be the average cost an IRS Form 1040 tax filing at Thetis Tax Service

P(X is given

From std normal distribution table we find 77th percentile z value.

z=0.74

Corresponding X value = 155

i.e. 0.74=\frac{155-138}{s} where s is the std deviation

Simplify to get

Std deviation  = \frac{17}{0.74} \\=22.97

What is the answer to 1/8(8x+15)=24
Korvikt [17]

Answer:

x = 177/8

Step-by-step explanation:

First, we must get rid of the fraction by multiplying 8 by both sides.

8 · 1/8(8x + 15) = 24 · 8

1(8x + 15) = 192

8x + 15 = 192

Then we simplify. First subtract 15 from both sides.

8x + 15 - 15 = 192 - 15

8x = 177

Then divide 8 from both sides.

8x/8 = 177/8

x = 177/8
