Answer:
150
Step-by-step explanation:
the bases are 60 and the sides are 90
Perimiter is adding up all sides A+B+C+D.
Rectangles have two sets of parallel lines the height and the width.
If we know one of the heights is 7 the. We can conclude the parallel side is also 7
So then the total perimiter 34 minus the heights is 20.
We know that there is another set of parallel sides, remaining and 20 is how perimiter is left
… so if you divide by 2 your left with one side which is the width
Answer 10
Answer:
0.3
Step-by-step explanation:
We can use Bernoulli estimation to solve this. P(g) = 0.8, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.8 = 0.2
Using the Bernoulli approximation:
P(n=2) = 10C2 * P(n)^2 * P(g)^8
P(n=2) = 45 * 0.2^2 * 0.8^8
P(n=2) = 0.30
Answer:
Reflection over y=x
Step-by-step explanation:
Answer: It is called a sample statistic.
Step-by-step explanation:
Since we have given that
A researcher records the time it takes to complete a memory task in a sample of 25 participants. He finds that the average participant completed the test in 43 s.
The average time to complete this task is called sample statistic.
As we know that
Sample statistic is the quantity which we get from the sample taken from a any specified population for using this quantity to calculate the same.
In our case, average participant completed the test = 43 sec.
It is sample statistic as we will use to find the average time for the population i.e. 25 participant to get the same calculation i.e. average time.
We will get average time is also equal to 43 sec.
Hence, it is called a sample statistic.
