Answer: the first picture is 36 cm^2.
Step-by-step explanation:
It's 36 cm^2 because you need to multiply the length and breadth which is 12*3= 36. Hope this helped !
Multiply all to find the area of any
Answer:
Step-by-step explanation:
Given the simultaneous inequality
2x+y<10 ....... 1
2x-4y<8 ....... 2
Subtract both equation from each other
(2x-2x)+(y-(-4y))<10-8
0+5y<2
y < 2/5
y < 0.4
Substitute the given value of y into 1;
2x+y<10
2x + 2/5 < 10
2x < 10 - 2/5
2x < 48/5
10x < 48
x < 4.8
Hence the solution to the inequality expressions is (4.8, 0.4)
Complete question is:
Seventy million pounds of trout are grown in the U.S. every year. Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 7 grams of fat per pound. A random sample of 34 farm-raised trout is selected. The mean fat content for the sample is 29.7 grams per pound. Find the probability of observing a sample mean of 29.7 grams of fat per pound or less in a random sample of 34 farm-raised trout. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
Answer:
Probability = 0.0277
Step-by-step explanation:
We are given;
Mean: μ = 32
Standard deviation;σ = 7
Random sample number; n = 34
To solve this question, we would use the equation z = (x - μ)/(σ/√n) to find the z value that corresponds to 29.7 grams of fat.
Thus;
z = (29.7 - 32)/(7/√34)
Thus, z = -2.3/1.200490096
z = -1.9159
From the standard z table and confirming with z-calculator, the probability is 0.0277
Thus, the probability to select 34 fish whose average grams of fat per pound is less than 29.7 = 0.0277
Answer:
15 rounds
Step-by-step explanation:
Change 75% into a decimal (0.75).
Multiply 20 by 0.75.
When doing so, you get 15 rounds.
To check this: 15/20 = 3/4 = 0.75
