Answer:
K = 97 degrees
Step-by-step explanation:
The four interior angles of a quadrilateral is always equal to 360 degrees.
127 + 88 = 215
(10x + 7) + (5x + 3) = 15x + 10
360 - 215 = 145
145 = 15x + 10
130 = 15x
9 = x
k = 10x + 7
k = 10(9) + 7
k = 97
Answer:
Probability = 0.00621
Step-by-step explanation:
We are given;
Population mean; μ = 400
Population standard deviation; σ = 20
Raw score; x¯ = 450
the probability that the actual costs will exceed the budgeted amount will be the p-value.
Thus, let's first find the z-score after which we will find the p-value.
z = (x¯ - μ)/σ
z = (450 - 400)/20
z = 50/20
z = 2.5
From online p-value from z-score calculator attached, using z = 2.5; one tailed hypothesis; significance level of 0.05, we have;
P-value = 0.00621
=(100-40)/2-30
=60/2-30
=30-30
=0
Answer:
E
Step-by-step explanation:
if we decidedly factor this expression-
4x^2+4xy+y^2
= (2x)^2 + 2*2xy + y^2
= (2x + y)^2
as you can see it is a perfect square so it can be grouped into (2x+y)^2
hence your solution is option e
