Answer:
19 )
do cross multiply
and answer will come
Step-by-step explanation:
w+ý=z/y
The slope is the change in Y over the change in X.
Use the two blue dots on the graph :
(-1,0) ans (3,4)
Slope = (4 - 0) / (3 - -1)
= 4 / 4
= 1
Answer:
144
Step-by-step explanation:
First, do the top and bottom. The top is 2*4*3 or 24, and the bottom is 6*4 or 24.
Now, do the sides. It is a staircase that you can split into 6 2x2 blocks, or 6*4=24. Do the same with the other side to get 24 again.
Now for the front and back. This is 2*4*3 and 6*4 again, or 24 and 24.
Now you have 6 24's so just multiply these and get 144.
Answer: B
Step-by-step explanation:
Answer: False
Step-by-step explanation:
We know that , If p-value < 
, we reject the null hypothesis .
If p-value ≥ , we are fail to reject the null hypothesis .
As per given , we have
The p value for an independent samples t-test is 0.043.
The level of significance is 
Since , 0.043 < 0.05.
i.e. p-value <
It means we reject the null hypothesis .
It means the null hypothesis is false.
Hence , the correct decision in this scenario is to favor the null hypothesis : False
