Answer: y=1
Step-by-step explanation:
First we need to get y alone.
y+3 = 4
We must subtract 3 on both sides (this will cancel out the +3 on the y side).
y=1
If you had y-3=4 then you would have to add 3 on both sides to cancel out the -3 on the y side.
If it is division you multiply and vise versa. Just do the opposite to everything on the y side to give y alone and figure out what y is equal to!
:) Best of luck!
It is 2/6
Because (1/6) * 2 = 2/6
Answer:
52 cubic units
Step-by-step explanation:
1. Divide the shape into 2 parts:
The first one: a 2 by 4 by 6 rectangular prism.
The second one: a 1 by 4 by 1 rectangular prism.
2. Find the volumes of the prisms.
2*4*6=48
1*4*1=4
3. Add the two volumes
48+4=52 cubic units (or units^3)
Answer:
most of the students will vote in the following presidential elections because the p value is lower than the level of statistical significance
Step-by-step explanation:
Alfa=0.05
so we have to
P-value is 0.02
considering that alpha is greater than p
P-value (0.02) < alpha (0.05)
we conclude that the null hypothesis is rejected
Interpretation
Taking the alpha value as the statistical level of significance, it can be said that more than 50% of the students will vote in the following presidential elections.
Answer:
A) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.
B) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.
C) False : Null Hypothesis can be accepted, despite of being actually false. This is called Type 2 Error.
Step-by-step explanation:
Hope this helps:)
