Step-by-step explanation:
mean score means the sum of all 6 scores divided by the number of games : 6.
sum6/6 = 15
sum6 = 15×6 = 90
(sum6 + x)/7 = 16
sum6 + x = 16×7 = 112
90 + x = 112
x = 22
they scored 22 points in the 7th game.
Answer:
P(X < 3) = 0.7443
Step-by-step explanation:
We are given that the random variable X has a binomial distribution with the given probability of obtaining a success. Also, given n = 6, p = 0.3.
The above situation can be represented through Binomial distribution;

where, n = number of trials (samples) taken = 6
r = number of success = less than 3
p = probability of success which in our question is 0.3.
LET X = a random variable
So, it means X ~ 
Now, Probability that X is less than 3 = P(X < 3)
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
= 
=
= 0.11765 + 0.30253 + 0.32414 = 0.7443
Therefore, P(X < 3) = 0.7443.

hexa means 6, so I would assume 6x5 = 30 ft, but then you want to have a side open for a 'door', so subtracting 5 would make the answer 25ft.<span />
Answer:
B 3x+2
Step-by-step explanation:
perimiter=2L+2W
P=2(L+W)
if x=width then
P=2(L+x)
P=8x+8
hmm
8x+8=2(L+x)
distribute
8x+8=2L+2x
minus 2x both sides
6x+8=2L
divide both sides by 2
3x+4=L
the length is 3x+4
B is answer
