Answer: probability sampling
Step-by-step explanation:
Probability sampling is used as a sampling method in which the researcher chooses samples from a large population using a method which is based on the theory of probability. For an item to be qualify as a probability sample, that item must be selected using a random selection. An example is the selection of 2 girls from a group of 20 students where 12 are girls and 8 are boys.
So b/10 has to be -1, that means b is -10
They should use the conversion factor
1 mile = 5280 feet
To go from feet to miles, you divide by 5280
So,
4224 ft = 4224/5280 = 0.8 miles
The distance between their homes is exactly 0.8 miles
Answer: Adelia brought a snack that costed 3 dollars.
Step-by-step explanation:
4 quarters in each dollar
(4dollars*4quarters)
$4.00=16 quarters
(she found 2 more quarters)
16+2=18
0.25*18= $4.50
She brought a snack that left her with 6 quarters ($1.50)
$4.50-$1.50=$3.00
Adelia brought a snack for $3.00
