Answer:
there are 380 seats in total
Step-by-step explanation:
286 + 18 = 304 which is four-fifths of the seat. since 304 seats is 80% of the total seats then if you divide it by 80 then multiply it by 100 you get 380.
so one fifth would be 76 seats and if you multiply it by 4 you get 304 which is four fifths of the seat.
Answer:
y=-2x + 5
Step-by-step explanation:
y=mx+b
m=slope
b= y intercept
since on the y line the line intercepts on 5 you replace 5 with the b.
As for the m(slope) when the line is decreasing (going down) its automatically a negative number. and since (0,5) (1,3) 5-3=2 -2 would be ur slope.
Answer:
The variable x will follow a geometric distribution, with mean = 3 and standard deviation = 3.46.
The values for P(x) are:
Step-by-step explanation:
This kind of random variables can be descripted by the geometrical distribution.
This distribution shows the probability of having an amount of "failures" before the first "success" (or the other way).
Let x be the number of trustworthy FBI agents tested until someone fails the test. The probability of failing a test is p=0.25
Then, the probability of x is:
The values for the first x are:
This probability will be descending as the the variable x increases.
The mean is:
The standard deviation is:
Answer:
a
Step-by-step explanation:
The zeroes of a function are when y = 0 so we can write 0 = 2x - 4 so we have to solve for x and when we do so we get x = 2.
