Answer:
y = -1/16 (x-3)^2 - 1: This is the vertex form
y = -1/16x^2 + 6/16x - 25/16: This is the standard form.
Step-by-step explanation:
Got the answer right when I did the question.
Step-by-step explanation:
We have to find what one share is
we have 3 shares + 2 shares + 5 shares
so he have a total of 10 shares
next, we divide 50 by total shares to get what one share is
50 ÷ 10 = 5
5 is one share
fins what each is
for 3
3 shares so 3 fives
3 × 5 = 15
for 2
2 shares so 2 fives
2 × 5 = 10
and for 5
can you work it out and leave in the comments i will say if it is correct
F(x) = 40 - 1.25x is a function.
Answer:
P(X<1200) is 0.8212
Step-by-step explanation:
Test statistic (z) = (X - mean)/sd
X is score of a tester = 1200
mean = 1497
sd = 322
z = (1200 - 1497)/322 = -297/322 = -0.92
The cumulative area of the test statistic is the probability that X<1200. The cumulative area is 0.8212.
Therefore, P(X<1200) = 0.8212
