Answer:
w=12
l=20
Step-by-step explanation:
The area can be found using the following equation:
Given the information provided, we are also told the following:
Therefore, we can plug in our length and our area:
We can solve by using the quadratic formula.
w=12, so w+8=20.
Answer:
Accept the null hypothesis if it is two tailed test.
Step-by-step explanation:
The null hypotheses can only be accepted if it is a two tailed test and calculated chi square must be less than the critical value of chi square.
Then the difference between the the observed and expected frequencies will be zero.
where
H0 : σ²-σ²= 0 Ha: σ²-σ²≠0
For this the critical region would be greater than the calculated value of chi square. If so we will accept the null hypothesis and reject the alternative hypothesis.
Answer:
y = [-½]x + [-5]
Step-by-step explanation:
Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.
m = slope = ∆y/∆x
Using two pairs of values from the table, (-2, -4) and (0, -5),
Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2
m = -½
b = y-intercept = the value of y when x is 0 = -5
b = -5
✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b
Thus:
y = [-½]x + [-5]
