There are 8 test scores and 4 of them are lower than 73. 4/8 = .5 or 50%
So 50% of these test scores are less than 73.
Answer:
c = 8.06
Step-by-step explanation:
Use the Pythagorean theorem.
a^2 + b^2 = c^2
c^2 = a^2 + b^2
c^2 = 4^2 + 7^2
c^2 = 16 + 49
c^2 = 65
c = sqrt(65)
c = 8.06
X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
She would have paid 1,575 dollars plus the 800 down payment. The total would be $2,375.
The probability of getting heads on the first toss is 1/2 .
Then, the probability of getting heads on the second toss is 1/2 .
Then, the probability of getting heads on the third toss is 1/2 .
The probability of all three things happening is ...
(1/2) x (1/2) x (1/2) = 1/8 = 0.125 = 12.5% .
