Answer:
A
Step-by-step explanation:
You find the mean by adding all the values then dividing that sum by the amount of values
You find the median by putting the numbers in order from least to greatest and then find the middle number.
Answer:
16
Step-by-step explanation:
CE/2 = CF -->
32/2 = CF -->
16 = CF
2w + 2l = 354 where w = width and l = length
so we have
2*82 + 2l = 354
2l = 254 - 2*82 = 190
l = 95
length is 95 yards
Answer:
A. The situation is discrete B. i. { x : 0 ≤ x ≤ 6; x ∈ Z} ii. { C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Step-by-step explanation:
A. The situation is discrete since we have integral values for the amount paid per mile walked. The amount per mile is $5 and is only paid if a complete mile is walked. So, it is a discrete situation.
B. i. Since 0 miles represents 0 distance and the student walks a maximum of 6 miles, let x represent the distance walked. So the domain is 0 ≤ x ≤ 6 where x ∈ Z where Z represent integers.
{ x : 0 ≤ x ≤ 6; x ∈ Z}
ii. Since at 0 miles the amount earned is 0 miles × $5 per mile = $ 0 and at the maximum distance of 6 miles, the amount earned is 6 miles × $5 per mile = $ 30, let C represent the amount donated in dollars. So the range is 0 ≤ C ≤ $ 30 where C = 5x.
{ C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Answer: $2520
Step-by-step explanation:
The simple Interest earned on a deposit of P that has a rate of r% and a period of t years can be calculated by using the formula:
(P × R × T)/100
where P is principal
R is rate
T is time
P=$10,500
R=6%
T=4 years
Therefore:
Interest= (10500 × 6 × 4)/100
= 252000/100
= 2520
Sally will earn $2520 as interest after 4 years.
