Answer:
(13×14×6)/3= 364 centimeter cube
I answered wrongly cuz forgot to divide by 3
my mistake
Answer:
y=9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that dont contain the variables
move variable to left side and change its sign
42-7y+3y=6 collect like terms
-7y +3y=6-42
-4y=6-42
-4y=-36 divide both sides of the equation by -4
y=9
hope that helps :)
Answer:
what are u asking here?........
Answer:
a) State the random variable
Random variable : x
which refers to a randomly selected student from the college that is left-handed.
b) state population parameter
population parameter : P
which is the percentage of all students from the college that are left handed
c) state the hypotheses
The hypothesis are;
Null hypothesis H₀ : p = 0.11
Alternative hypothesis H₁ : p > 0.11
d) State the Type I error in the context of this problem.
Type - I Error: Rejecting that the % of all the students from the college that are left-handed is 11% when actually the % is really 11%
(Reject H₀ when H₀ is true)
e) State the Type 11 error in the context of this problem
Type-II Error: Failing to Reject that the % of all the students from the college that are left-handed is 11% when the % is really higher than that
(Fail to reject H₀ when H₀ is false)
The difference between speeds, during the first 20 minutes and last 20 minutes, would be 4.3 miles. The key word here is difference which automatically tells us to subtract. In this case you would subtract 6.8 miles, the last 20 minutes, by 2.5 miles, the first 20 minutes. In the end, getting 4.3 miles. Hope this helps! :)
