Answer:
a) P(not red) = 37/49
b) P(purple) = 17/49
Step-by-step explanation:

Answer:
a) 
b) She needs 5 consecutive free throws in order to raise her percent to
85 %
Step-by-step explanation:
We know that a basketball player made 12 out of 15 free throws she attempted.
We can calculate its percent of successful free throws as :

%
Now, If she wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85 % we can write :
(I)
In the equation (I) ''n'' represents the number of consecutive free throws she must have to raise the percent to 85 %.
We answer
a) 
b) Now we need to solve the equation (I) :
⇒
⇒
⇒
⇒ 
We found out that she needs 5 consecutive free throws to raise the percent of successful free throws to 85 %.
We can verify by replacing the value of ''n'' in the equation (I) ⇒
⇒
⇒
Their angles/lengths (depending on which type of graph you are using) would be the same.
Answer:
First question D
Second question C
Step-by-step explanation:
First question:
You lose 10 (-10), then lose 5(-5)
-10 - 5 = -15
Second:
-3 - 4 - 3= -10
Sparkle is longer because 464 as cm is 46.4, consequently longer thatn 46 cm.
