Answer:
Step-by-step explanation:
3 ÷ 2 1/3
2 1/3 can be written as
Now we divide 3 by 7/3
Now we flip the fraction 7/3 and multiply with 3
We cannot simplify it
So 9/7 is the final answer
Answer:
mean = 85, standard deviation = 3.5
Step-by-step explanation:
The empirical rule states that for a normal distribution, 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviation of the mean and 99.7% falls within three standard deviation of the mean.
From the diagram since the shaded are is approximately 95% of the data. Hence 95% falls within two standard deviations of the mean.
σ = standard deviation, μ = mean
Hence; μ ± 2σ = (78, 92)
μ - 2σ = 78 (1);
μ + 2σ = 92 (2)
Adding equation 1 and 2, gives 2μ = 170
μ = 85
μ - 2σ = 78
85- 2σ = 78
2σ = 7
σ = 3.5
Answer:
linear
Step-by-step explanation:
linear means that is gains and loses in a straight line. if you were to graph the points on a chart the line will be straight
you can see in set 1 there is one ball
1:1
set 2 is 2 balls
2:2
and set 3 is 3 balls
it increases at a steady rate
therefore it is linear
Answer:
27 mm
Step-by-step explanation:
The perimeter of the triangle is the sum of all sides lengths. In given triangle
first side has the length of 11 mm, the second side has the length of 35 mm.
If the perimeter is 73 mm, then
