Answer:
vertex = (3, 6 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = 2(x - 3)² + 6 ← is in vertex form
with vertex = (h, k ) = (3, 6 )
Answer:
18
Step-by-step explanation:
f(2)=4x+10
f=(4)(2)+10
f=8+10
f=18
Answer:
Step-by-step explanation:
From the given information:
The sample size is 28
The population mean is 24.5 (ppb)
The sample mean is 225.3 (ppb)
Thus, the null and the alternative hypothesis can be computed as:
Null hypothesis:
Alternative hypothesis:
Answer:
a) The probability is 1/5
bi) The probability each ball is even will be 2/5
bii) The probability the sum of the numbers on the ball is not more than 10 is 16/25
(that's what I think it is)
