Answer: 400 liters
Step-by-step explanation:
set up a proportion and solve.
150/800 = 75/x
150x = 60,000
divide by 150
x = 400
45*6 = 270
280-270 = 10
45 can go into 280 , only 6 times, and their is a remainder of 10.
Answer:
If the scientist’s estimate about the number of fish in the lake is correct, then it is 44% likely to get 20 perch out of 50 with a tag.
Step-by-step explanation:
Let p be the proportion of tagged white perch in the Midwestern lake.
Scientist's claim is that p=
Let's test this hypothesis as:
p=0.30
p≠0.30
P-value of the test statistic will give the likelihood of getting 20 perch out of 50 with a tag if the scientist's estimate (
) is true.
Test statistic can be calculated using the equation
where
- p(s) is the sample proportion of white perch (
)
- p is the proportion assumed under null hypothesis. (0.30)
- N is the sample size (50)
Then
≈ -0.77
Two tailed p-value of the test statistic is ≈ 0.44
Thus if the scientist’s estimate about the number of fish in the lake is correct, (p=0.30) then it is 44% likely to get 20 perch out of 50 with a tag.
Answer:
84,872 square feet
Step-by-step explanation:
I don't know what your answers are but all I did was devide 412 by 2 to get 206, then multiplied 206 and 412 (width x length) to get 84, 872 square feet.
oh no im just noticing that you said 4 1/2 please ignore my answer omg
