Answer:
10000
Step-by-step explanation:
multiply 100 by 100 then multiply that 4 times of the same number
130, is the answer.. so here's me having to come back and to explain,because this questions is SO hard.
They ask to round to the ten.
128
^This is ten, so we look to our right which is eight, is higher than 5. 5 is counted as higher. So 8 is over five and if we round 28, it's 30.
WOW, fascinating.
Thanks Brainly's "monitors" such help. -_-
- 7 1/5 < - 2.3 < 0 < π < 23/7 is ascending order of these numbers.
What do descending order and ascending order mean?
- Climbing down the stairs of numbers starting with their highest value is another way to think of descending.
- The slide is descended while moving down it.
- Ascending order, in which the numbers are organized from lower value to higher value, is the reverse of falling order.
The values are 0 , -2.3 , π , 23/7 , -71/5
first simplify all the values 0 , - 2.3 , 3.14 , 3.28 , -7.2
now arrange all value in Ascending order
- 7.2 < -2.3 < 0 < 3.14 < 3.28
- 7 1/5 < - 2.3 < 0 < π < 23/7

Answer:
The hippocampus volumes in the alcoholic adolescents are less than the normal volume of 9.02 cm³
Step-by-step explanation:
Let x= the hippocampus volumes in the alcoholic adolescents
We'll conduct a hypothesis test at the 0.01 significance level with
Null hypothesis: x = 9.02 cm³
Alternate hypothesis: x < 9.02 cm³
A sample of 13 alcoholic adolescents gives the parameters
size=N= 13
mean=M= 8.12 cm³
standard deviation= s= 0.8 cm³
According to the sample, with 99% confidence, t statistic for the value X=9.02 can be found using the formula:
t=
where
- M is the sample mean (8.12)
- s is the standard deviation of the sample (0.8)
- N is the sample size (13)
If we put these numbers in the formula:
t=
=4.056
One tailed critical value for the sample with 12 degrees of freedom (sample size-1) in 99% confidence level is 2.681.
Since t value (4.056) is bigger than the critical value, we fail to reject the alternate hypothesis, therefore reject the null hypothesis and accept alternate hypothesis.
