Answer:
3/16
Step-by-step explanation:
since the question has "and" we will be multiplying two unrelated probabilities
P(gray on 1) = 1/4
P(blue on 2) = 3/4
the second probability is not affected since we are not taking away the first space after we land on it
1/4 * 3/4 = 3/16
Answer:
456
Step-by-step explanation:
Let X be the SATscore scored by the students
Given that X is normal (1000,200)
By converting into standard normal variate we can say that
is N(0,1)
To find the top 10% we consider the 90th percentile for z score
Z 90th percentile = 1.28

i.e. only students who scored 456 or above only should be considered.
Answer:
Step-by-step explanation:
use these two equations
A: y = 15
B: y = 2r + 5
a) set the equations equal to eachother for your first answer
15 = 2r + 5
B) solve for r
15 = 2r + 5
10 = 2r
5 = r
after 5 rides the cost will be the same
Answer:
its 21
Step-by-step explanation:

Answer:
Step-by-step explanation:
The factoring of 64 is ...
64 = 2·2·2·2·2·2
= (2·2)·(2·2)·(2·2) = 4·4·4 = 4³
= (2·2·2)·(2·2·2) = 8·8 = 8²
= 2·2·2·2·2·2 = 2⁶
