Answer:
true
Step-by-step explanation:
because its 70 thousand
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:
9
Step-by-step explanation:
|9| = 9
Absolute value is distance from zero. 9 is 9 away from 0. BRAINLIEST? :')
Answer:
1.125
Step-by-step explanation:
1) First you have to turn it into an improper fraction
8*1 = 8. Add the numerator--> 8+1 = 9.
2) The improper fraction is 9/8
3) Divide 9 by 8
**Write this using long division
8 goes into 9 one time, so we will write one as our first digit
Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.
And this point we have 1.1 above
Carry down the 2 and the 0, 8 goes into 20 2 times so write 2
At this point we have 1.12
Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.
Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.
A factor pair of 13 would be:
1 * 13
or
13 * 1
Hope this helps!
