1.
(3x - 5 ) + (-4x + 1)
= 3x - 4x -5 + 1
= -x - 4

2.
6(-2.1k - 2) + (7k + 5)
= (-12.6k - 12) + (7k + 5)
= -12.6k + 7k - 12 + 5
= -5.6k - 7

3.
(2m + 7) - (3 - 4m)
= 2m + 7 - 3 + 4m
= 6m + 4

PLSSS HELP IF YOU TURLY KNOW THISS
xxMikexx [17]

Answer:

2 1/2

Step-by-step explanation:

Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.

4 3/4

4 * 4 + 3 = 19

19/4

2 1/4

2 * 4 + 1 = 9

9/4

Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.

19/4 - 9/4 = 10/4

Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:

4 * 2 = 8

10 - 8 = 2

2 1/2

A day care program has an average daily expense of $75.00. The standard deviation is $15.00. The owner takes a sample of 64 bill
Naddika [18.5K]
The sample mean is approximately normally distributed with mean $75.00 and standard deviation $15.00/sqrt(64)

1) The z-score for $70.00 is

(70 - 75)/(15/8) = -2.66667 = -2.7 to the nearest tenth.

2) The probability corresponding to this z-score is 0.0035 (use standard normal tables), or 0.35%, which rounded to tenths is 0.4%

I will leave the rest to you. The instruction in step 5 is wrong; you do not add the probabilities from steps 1 and 3. (If you do add them, you will get 1, which is clearly the wrong answer.)

P(70 < sample mean < 80) = P(sample mean < 80) - P(sample mean < 70)

so you should subtract the result in step 1 from the result in step 3.

The correct answer is 0.993, or 99.3%
