Answer:
a) $170
b) 12
Step-by-step explanation:
A = 250 - 20t
where A is Jina's account balance and t is the number of trips she takes.
a) If Jina takes 4 trips, then t = 4.
Substitute t = 4 into the given equation:
A = 250 - (20 x 4)
= 250 - 80
= 170
So Jina has $170 left in her account after 4 trips.
b) The calculate the maximum number of trips Jina can take without running out of money, set A to zero and solve for t:
when A=0: 0 = 250 - 20t
Add 20t to both sides: 20t = 250
Divide both sides by 20: t = 12.5
Therefore, Jina can take 12.5 trips. However, she can't take a half-trip so we should round the number down to 12 trips (as after 12 trips she will only have enough money left for half a trip).
So, the largest number of trips Jina can take without running out of money is 12.
Answer:
A D E
Step-by-step explanation:
the figure shows that ABC is 90 degrees. So the two smaller angles add to 90 making A correct. (B isn't for obvious reasons - 180 is not 90.)
x + 4x - 85 = 90 Solve this to find the other 2 correct statements
5x - 85 = 90 Add 85 to both sides.
5x = 90 + 85 Combine
5x = 175 Divide by 5
5x/5 = 175/5
x = 35
Since ABD is a single x, that statement (D) is true.
4x - 85 = 4*35 - 85 = 140 - 85 = 55 which makes E true as well
Answer:
57.885
Step-by-step explanation:
For such calculations a probability calculator is very helpful. The one in the attachment shows the 87th percentile to be 57.885.
___
A table of the standard normal distribution will tell you the 87th percentile corresponds to a z-value of 1.12639. Then the X value is ...
X = Zσ +μ = 1.12639(7) +50 = 57.885
