Answer:
Step-by-step explanation:
1 - 2 + 10 o lw. First find a common denominator. 3 * 5. After cross reducing, multiply across ... Divide the fraction to get a decimal answer. 21 into a an. Jinit. 5 = 1.25 ... 3 = -x +8. -8 = -8. = -5 = -X. =-1(-5) = -x (-1). = 5 = x. Set up a ratio, and cross ... Combine like terms, and solve for x. Divide both sides by 2. = x= 20. = 5-1">4.
Answer:
Step-by-step explanation:
Let X be the variable representing SAT critical reading scores for which the mean is 507 and std dev is 109
X is normal
Critical score for 95% is Z critical = ±1.96
Convert Z to x score as
Critical values of X lie in the range
(293.36,720.64)
Answer:
x = 15
Step-by-step explanation:
Given: ∠RST = 65, m∠QST = 2x, and m∠QSR= 3x – 10
∠QST + ∠QSR = ∠RST
Plug in
2x + 3x – 10 = 65
Combine like terms
5x - 10 = 65
Add 10 to both sides
5x = 75
Divide both sides by 5
x = 15
So answer: x = 15
