Answer:
x=-3 and y=-2
Step-by-step explanation:
let the numbers be x and y
x+y=-5
x-y=-1
therefore x=-5-y
-5-y-y=-1
-2y=-1+5
-2y=4
y=-2
×=-5-(-2)
x=-5+2
x=-3
For a binomial distribution, the variance is

Answer:
Carter's bedroom would cost more to carpet than Carly's because the floor area of the former is about five square feet greater than the floor area of Carly's bedroom.
Step-by-step explanation:
The area of either of these floors is found by multiplying length by width:
A = L*W.
Carly's bedroom is 15.3 ft by 8.7 ft; multiplying, we get A = 133.11 ft^2
Carter's is 14.4 ft by 9.6 ft: A = 138.24 ft^2
Carter's bedroom area (138.24 ft^2) is about 5 ft^2 larger than Carly's and would thus cost more to carpet.
the two coterminal angles to the given one are:
8.98 rad and -3.58 rad
<h3>How to find coterminal angles?</h3>
For a given angle A in radians, the family of coterminal angles is defined as:
B = A + n*(2*pi)
Where pi = 3.14 rad
Where n can be any integer number.
In this case, we have an angle of 2.7 radians, then the coterminal angles are:
B = 2.7 rad + n*(6.28 rad)
One positive is what we get if we select n = 1, then:
B = 2.7 rad + 1*(6.28 rad) = 8.98 rad.
And if we select n = -1, we get the negative coterminal angle:
B' = 2.7 rad - 1*(6.28 rad) = -3.58 rad
Then the two coterminal angles to the given one are:
8.98 rad and -3.58 rad
