The % margin of error means that the real value is in the range between the mean less the margin error and the mean plus the margin error. This is [ mean - % of error, mean + % of error]. Then, in this case the error of +/- 2% means that the expected population proportion that wants flexible working hours is between 60% - 2% and 60% + 2%, which is<span> between 58% and 62%. </span>

Find the distance between points P(9,8) and Q(7,6) to the nearest tenth.
sergey [27]

Answer:

2.8 units

Step-by-step explanation:

Think of this distance as the hypotenuse of a right triangle that has a vertical leg and a horizontal one as well.

Going from P to Q, the change in x is 2 and the change in y is also 2.

Thus, by the Pythagorean Theorem, this desired distance is:

d = √(2^2 + 2^2) = 2√2 units, or 2.8 units

How to find rate of change on a table
LekaFEV [45]

Answer:

   __X__l__Y_

        1     l    3

        5    l    6

        9     l    9

        13   l    12

        17   l    15

        21   l    18

On the right side, the numbers get larger by adding three each time. On the left side, the numbers get larger by adding 4 each time. It would be the same for any other pair of numbers when you add 4 to the left, and 3 to the right. For instance, the next pair would be (25 , 21). 25 would be the X value, and 21 would be the Y value.

Phoenix [80]

For a. divide 125 by 300 then multiply by 100

The answer for b. is $1.91

For c. you have to figure out the difference first. 2.50 minus 2.00 is 0.50

So then what percent of 2.00 is 0.50

Divide 2.00 by 0.50 to get 4.

The answer for c. is 4%

Honestly this was kinda rushed because I'm in the middle of a quiz so yea hope this helps you.

From yours truly to you,

Jeff bought 4 oranges and 7 apples for a total of $4.88. Gene bought 12 oranges and 8 apples for a total of $7.88. What is the c
rjkz [21]
4x+7y=4.88 -> mult by -3 -> -12x-21y=-14.64
12x+8y=7.88
-12x-21y=-14.64
Add the two above equations together, the y will be left:
-13y=-6.76
y=0.52 —> cost of each apple (plug back into one of original equations, I chose 4x+7y=4.88:
4x+7(0.52)=4.88
Solve for x.
x=0.31 —> cost of each orange
