Answer:
36
Step-by-step explanation:
From first roll, there are 6 possible outcomes (1,2,3,4,5,6)
From the second roll, also 6 outcomes (1,2,3,4,5,6)
6*6=36
Each box should be 2. If you subtract the number next to x on both sides of each inequality, you end up with x > 2.
PS. Thanks for marking me brainliest on the other problem :)
11.2+4+3.4+7.3+(11.2-3.4)=
11.2+4+3.4+7.3+7.8=
33.7
your perimeter is 33.7 m
Answer:
Population Mean = 2.0
Population Standard deviation = 0.03
Step-by-step explanation:
We are given that the inspector selects simple random samples of 30 finished products and computes the sample mean product weight.
Also, test results over a long period of time show that 5% of the values are over 2.1 pounds and 5% are under 1.9 pounds.
Now, mean of the population is given the average of two extreme boundaries because mean lies exactly in the middle of the distribution.
So, Mean,
=
= 2.0
Therefore, mean for the population of products produced with this process is 2.
Since, we are given that 5% of the values are under 1.9 pounds so we will calculate the z score value corresponding to a probability of 5% i.e.
z = -1.6449 {from z % table}
We know that z formula is given by ;
~ N(0,1)
-1.6449 =
⇒
⇒
0.0608 *
{as sample size is given 30}
⇒
= 0.03 .
Therefore, Standard deviation for the population of products produced with this process is 0.0333.
