Answer:
a) p = 352/700 = 0.5029
b) p = 348/700 = 0.4971
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
There are 700 shoppers.
151 + 201 = 352 were happy with the service received.
133 + 215 = 348 were not happy with the service received.
(a) A shopper was happy with the service received.
352 happy out of 700
p = 352/700 = 0.5029
(b) A shopper was unhappy with the service received.
348 unhappy out of 700
p = 348/700 = 0.4971
Answer:
22. 18
23. 10
Step-by-step explanation:
22
- you plug the number for the variable into the equation (3(2)²+6
- order of operations say exponents first so you do 2²=4 so you have 3(4)+6
- then you multiple 3•4=12 so 12+6
- finally you add 12+6=18
23
- plug in the number for the variable so 5–(-5)
- so a negative and a minus will make it addition (negative + negative = positive)
- do it is 5+5 which equals 10
Answer: x = 1
Step-by-step explanation:
2.8 + 2x = 0.6 x 8
2.8 x + 2x = 4.8
2x = 4.8 - 2.8 (subtract 2.8 on both sides)
2x = 2
x = 1 (divide 2 on both sides)
Hope this helps
Answer:
15
Step-by-step explanation:
Hello!
To find the median, all you have to do is order the number of terms in ascending order and then count to the middlemost number(s).
Arranging in ascending order:
Since this is an even number, our two medians are 15 and 15.
(15 + 15) / 2 = <u>15</u>.
Thus, the median of successful free throws is .
