<u><em>Answer: y=42</em></u>
Step-by-step explanation:
division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
divide by -3 both sides of an equation.
-3(y-50)/-3=24/-3
simplify.
y-50=-8
add 50 both sides of an equation.
y-50+50=-8+50
simplify.
-8+50=42
50-8=42
42+8=50
y=42
Hope this helps!
Thanks!
Have a great day!
The answer is commutative property of addition
Answer: A. (2, 5), (3, 6), (6,9)
Step-by-step explanation:
Each value of x maps onto only one value of y.
Answer:
Mean = 272.3
sd = 37.7
Step-by-step explanation:
Mean = sum/n
(221+248+251+255+259+263+264+272+291+297+374) ÷ 11
= 2995/11
= 272.2727273
Variance = (sum of x²)/n - mean²
[(221²+248²+251²+255²+259²+263²+264²+272²+291²+297²+374²)/11] - (2740/11)²
= (831067/11) - (2995/11)²
= 1419.107438
sd² = variance
sd = sqrt(1419.107438)
sd = 37.67104243
the answer is A) s,q,b I'm pretty sure
