How to factor: b^2-6b+8

Answer:

x = 1/4

Step-by-step explanation:

20x - 5y = 10

8x + 5y = -3

28x = 7

x = 1/4

The new mean becomes 87 (40*2+7), while the new standard deviation becomes 10 (5*2). The correct option is then option D.

hope this helps! please give brainliest :)

Answer:

Step-by-step explanation:

Applying the formula for normal distribution,

z = (x - u)/s

Where u = mean

s = standard deviation

x = the monthly utility bill in dollars

From the information given,

s = 23

u = 121

The probability that a randomly selected utility bill is between $110 and $130 is expressed as

P(110 lesser than or equal to x lesser than or equal to 130)

For 110

z1 = (110 - 121)/23 = - 11/23

z1 = - 0.4783

Looking at the normal distribution table,

The corresponding z score is 0.3192

For 130

z2 = (130 - 121)/23 = 9/23

z2 = 0.391

Looking at the normal distribution table,

The corresponding z score is 0.65173

P(110 lesser than or equal to x lesser than or equal to 130) = 0.65173 - 0.3192 = 0.33253

Answer:

24π/5, 63/4, 15.758, 956√e

Note: The correct question is found in the attachment below

Step-by-step explanation:

Dividing to get values up to three decimal places

π = 3.142; e = 2.718

24π/5 = 24/5 × 3.142 = 4.8 * 3.142 = 15.0816

63/4 = 15.750

15.750 = 15.750

956 × √e

√e lies between 1.6 and 1.65 because 1.6 × 1.6 = 2.56

1.65 × 1.65 = 2.7225

Using 1.65

956 × 1.65 = 1577.4

Therefore, the correct ordering is 24π/5, 63/4, 15.758, 956√e
