Answer:
<u>always</u>
Step-by-step explanation:
For this hypothesis test:
<u>The Decision rule: </u> To reject the null hypothesis 
if the p-value is lesser than < the significance level.
At the level of significance 0.01, the null hypothesis is rejected.
So, p-value < 0.01 and this typically shows that p-value is < 0.05.
Therefore, it will <u>always</u> be rejected at ∝ = 0.05
First, you substitute each x in the first equation- 2(2y+10)-3y=17
Next, simplify - 4y+20-3y=17
y+20=17
y=-3
Next, substitute the y in for the second equation, x=2y+10
x=2(-3)+10
x=-6+10
x=4
ANswer:
x=4
y=-3
Hope this helps!
Answer:
what points
Step-by-step explanation:
Answer:
The enlarged height of the photo must be 682 inches
Step-by-step explanation:
A customer wants to enlarge the image by 22 times
Hence, the scale factor = +22
Now, the current height of the photo = 31 inches
Therefore, to find the enlarged height : we need to multiply the scale factor of the required image by the current height of the photo.
Hence, Enlarged Height = 22 × 31
= 682 inches
So, The enlarged height of the photo must be 682 inches
