Answer:
a. 135 is correct
Step-by-step explanation:
We have the following information:
dogs lover: 150
cats lover: 120
as the null hypothesis:
H, there are equal number of dogs lover and cats lover, so the expected frequency in each cell will be equal and that is:
f = (150 + 120) / 2
f = 270/2 = 135
so option a. 135 is correct
Answer: 10^3
Step-by-step explanation:
Since the problem is displayed at , you see that there is a parenthesis separating the and the 3. In long story short, if you see a parenthesis, if means to multiply.
I'm smart but you probably wont like me
First off, a triangle's int. angles = 180.
Since it is isosceles, you can make this formula.
180 = 2(4x-11) + 2(6x+1)
Now, you have to solve for x.
180 = 8x - 22 + 12x + 2
180 = 20x - 20
200 = 20x
/20 /20
10 = x
Now substitute
10(6) + 1
60 + 1
61
61 times 2 = 122.
Therefore, angle NLM is 122 degrees.
Proof:
4(10) - 11
40 - 11
29
29 + 29 + 122 = 180
Answer:
y=-12
Step-by-step explanation:
Step 1: Add -14 to both sides.
Step 2: Divide both sides by -i.
