Answer:
The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.
Step-by-step explanation:
For a beta distribution with α = 2 and β = 9, we need to use a calculator to compute the probabilities.
The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.
Answer:
5: given y=2x-2 new y=2x+2
6: given y=-1/4x+4 new y=-1/4x+7
Step-by-step explanation:
Answer:
k = 13
Step-by-step explanation:
Matrix is;
A =
[2 -5 9]
[-1 3 -5]
[ 7 1 k ]
Number of unknowns is less than the rank of 2. Thus, the determinant has to be zero for us to find k.
Thus, we have;
2((3 × k) - (-5 × 1)) -(-5)((-1 × k) - (-5 × 7)) + 9((-1 × 1) - (7 × 3)) = 0
Simplifying further gives;
2(3k +5) + 5(-k + 35) + 9(-22) = 0
6k + 10 - 5k + 175 - 198 = 0
k - 198 + 185 = 0
k - 13 = 0
k = 13
Answer:
The answer is 6.451 or 6.5 rounded
Step-by-step explanation:
The way to solve this is to find all the degrees inside the triangle first
you have two given degrees which are 21 and 90 degrees
add those numbers up and subtract it from 180. That is the last corner degree
you then use that information to find all the side lengths using the given hypotenuse length.
Btw its geometry not really trig.
