Answer:
The type of sampling method Dr. Lawrence going to use is Quota Sampling.
Step-by-step explanation:
In quota sampling participants are chosen nonrandomly so it is not a representative sampling method. In this case Dr.Lawrence has a quota of 15% for first-time students and 85% for returning, so the survey she is conducting is non-random. The sampling method she should use is Quota Sampling.
Answer:
20 ounces of cleaner
Step-by-step explanation:
Water 48 oz is 60% of unknown total. 60% = 3/5. Create equation and solve
48= 3x/5. 240= 3x. 80 = x
Total of water, bleach and cleaner is 80 ounces
60% + 15% = 75%
100% - 75%= 25% cleaner
.25 × 80 = 20 ounces
Yes, I think so because if it’s basically 8:30 and she is 3/4 miles away from her house, she is almost at school
Answer:
8 years
Step-by-step explanation:
Let age of father be f
age of John be j
age of Alice be a
John's father is 5 times as old as John. We can write:
f = 5j
John is twice as old as Alice. We can write:
j = 2a
or
a = j/2
SUM OF ALL OF THEIR AGES (after 2 years) will be 58. We can write:
f+2 + j+2 + a+2 = 58
This becomes:
f + j + a + 6 = 58
f + j + a = 52
Now, we replace third equation with the first two (in bold) and get:
So John is 8 years old
