Answer:

29. A  30. $7.50 31.  1(2) 1(3) 3(4) 1(5) 1(6) 1(7)

Step-by-step explanation:

29.

multiply $2500 by the percentage (ie. 24%) that is how to get the amount.

30.

if 4 boxes equal $5.00 and Jeniffer has 6 then 4 of her 6 equal 5.00 and half of five is 2.50 which mean the 2 remaining would be added and would equal $7.50

31.

you add 1 dot to the top of the number for every time that one number shows up (example: if you have 3 2's, then you add 3 dots to the top of the number 2)

Gnesinka [82]

We are given the following data:

Sample Size = n = 1000

Sample Mean = u = 15 hours

Population Standard Deviation = s = 2 hours

Since we know the population standard deviation, we can use z distribution to find the confidence interval about the mean. z value for 95% confidence interval is 1.96.

Formula for the confidence interval is:

(u-z\frac{s}{\sqrt{n}} ,  u+z\frac{s}{\sqrt{n}})

Using the values in the formula, we get:

(15-1.96\cdot\frac{2}{\sqrt{1000}},  15+1.96\cdot\frac{2}{\sqrt{1000}})\\ \\  (14.88,15.12)

Therefore, the 95% confidence interval about the population mean is 14.88 hours to 15.12 hours. So B option is the correct answer.

Solve 5x-y=5 and 2y-x^2=11 without using trial improvement
iren2701 [21]

Answer:

x = 7, y = 30  and  x = 3, y = 10

Step-by-step explanation:

5x - y = 5, then y = 5x - 5

2y - x^2 = 11

2(5x - 5) - x^2 = 11

10x - 10 - x^2 = 11

-x^2 + 10x -10 = 11

-x^2 + 10x -21 = 0

x^2 - 10x + 21 = 0

(x - 7)(x - 3) = 0

x = 7, y = 30

x = 3, y = 10
