Answer:
Option A.
Step-by-step explanation:
In an experiment a mouse took the mean time to find its way through a maze = 18 seconds.
So the mean time μ = 18
So null hypothesis says,
H₀ : μ = 18
Then a researcher thought that the mice can complete the maze faster than the time taken earlier.
So he thinks mean time taken by 10 mice will be less than 18 seconds.
Or μ < 18
Alternate hypothesis says will be
Hₐ : μ < 18
Therefore, null hypothesis and alternate hypothesis will be
H₀ : μ = 18
Hₐ : μ < 18
Option A. will be the answer.
Answer:
-32/35
Step-by-step explanation:
-4/5 *8/7 you have to flip the right fraction to multiply since you cant actually divide
hope this helps
X/4 = r3 or 3/4
x/3 = r2 or 2/3
x/5 = r3 or 3/5
we know x is not divisible by 4 3 or 5 and is less than 30.
we know the value ends in 3 or 8 from x/5 = r3
we know the value is greater than 3 from r3
so far we got 13 and 23
13 is eliminated from x/4 = r3 because it is r1 not r3
so the answer is 23
The Y-intercept is a point where the line crosses the Y lines. That means it would be the point where X=0. Then to find the Y-intercept you only need to insert X=0 into the equation. The calculation would be:
<span> 4×+2y=12
4(0) + 2 Y= 12
2Y =12
Y=6</span>
