B
given f(x) in factored form, equate to zero for x-intercepts
(x - 8)(x - 4) = 0, hence
x = 4, x = 8 ← x- intercepts
The vertex lies on the axis of symmetry which is situated at the midpoint of the x- intercepts
x- coordinate of vertex = 
= 6
f(6) = (6 - 8 )(6 - 4 ) = -2 × 2 = - 4 ← y-coordinate
vertex = (6, - 4 ) → B
Answer:
The correct answer is "Investigating the mean of the sample is the same as investigating the sampling distribution of the mean"
Step-by-step explanation:
For sampling distribution of the mean, if the size of population is n, and its mean is μ and the population standard deviation is σ, then the mean of all sample means also becomes equal to the population mean μ but for that the samples are taken randomly from the given population
Answer:
After 6 weeks the sunflower would be 43 inches tall. After w weeks, the sunflower would be 25 + 3w tall.
Step-by-step explanation:
the answer is 3/2
always remember when multiplying numbers of the same base the exponents will always be added and when dividing numbers of the same base the exponents will be minused.
-10b--3b= 7b and then 113-71=42 and 42 divide it by 7b which is gonna be b=6
