Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as then the equation relating them is
c = k ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k × = 8k ( divide both sides by 8 )
1.75 = k
c = 1.75 ← equation of variation
When d = 324 , then
c = 1.75 × = 1.75 × 18 = 31.5
Answer:
$80
Step-by-step explanation:
50/5= 10 this determines how many packages of cards she has
10 * $8 = $80 multiply the number of packages of cards by $8
(m-2n)(3+m-2n) is it factored.
Answer:
Result is significant ; hence we can conclude that the average age of male is greater than that of females.
Step-by-step explanation:
Given that:
Let :
u1 = mean age of male
u2 = mean age of female
Null hypothesis : H0 : u1 = u2
Alternative hypothesis : H1 : u1 > u2
P value for hypothesis test conducted = 0.0095
Using a significant level α 0.05 or 0.01, :
The P value < α
Since, the P-value is less than α, then the result is significant and we thus we can reject the Null and conclude that the average age of males is greater Than that of females that play on the golf course.
5: (8+1) • 12 -13
9(12)-13
108-13
95
7: Rectangle
The answer to 5 is 95 and the answer to 7 is rectangle.
Hope this helps!
