4 0

Answer:

The answer is 1000.

*Explanation*

Attendance at the football stadium is 100%

100% - 10% = 90%

10% = 100 attendance

900% = 900 attendance

900 + 100 = 1000 attendance

What is the probability that a value falls in the interval μ ± 2σ, that computes the probability P(-2 < Z < 2). Round to f
bija089 [108]

Answer:

0.9544    

Step-by-step explanation:

P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.

P(−2 < Z < 2) = F(2) - F(-2)

Using the Z - table,

F(2) = 0.9772

and F(-2) = 0.0228

Thus,

P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544

This means that data within two standard deviation is 95%.

Please look at the picture and answer it thank you.

Answer:

x = 17

Step-by-step explanation:

The sum of all angle measures in any triangle is 180 degrees.

  • Thus, 23 + 5x - 18 + 90 = 180.

Step 1: Simplify both sides of the equation.

  • (5x)+(23+90-18)=180
  • 5x+95=180

Step 2: Subtract 95 from both sides.

  • 5x+95-95=180-95
  • 5x=85

Step 3: Divide both sides by 5.

  • 5x/5=85/5
  • x=17

Step 4: Check if solution is correct.

  • (5*17-18)+23+90=180
  • 67+23+90=180
  • 180=180

Thus, x = 17.

My product is 30. The difference of the two factors is 1. The sum of the two factors is 11. What numbers am i?
cupoosta [38]

xy = 30

x - y = 1

x + y = 11

First, we need to consider factors of 30:

1, 2, 3, 5, 6, 10, 15, 30

Which two of these, subtracted, would equal 1?

5 and 6

6 x 5 = 30

6 - 5 = 1

6 + 5 = 11
