Answer:
x = - 4 or x = 20
Step-by-step explanation:
Given R is the midpoint of AM, then
RA = MR , substitute values
x² - 16x = 80 ( subtract 80 from both sides )
x² - 16x - 80 = 0 ← in standard form
(x - 20)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 20 = 0 ⇒ x = 20
x + 4 = 0 ⇒ x = - 4
46 + 176 = 222 males
254 + 364 = 518
Which is total of 740 people.
The probability of being male is 0.3
46 + 254 = 300 that bring lunch
176 + 264 = 440 that buy their lunch
P(male | buy lunch ) = 0.4
Answer D
Answer:
Answer is D, simplify the expression and solve.
You did the equation a little wrong. It is A^2 + B^2 = 10^2
Answer:
36
Step-by-step explanation:
