I think A, C, D are right because of the 12 pairs of heels, 6 are black (6/12) That means half of them could be chosen and be black (0.5). Another way to write 0.5 is as a percentage, 50%.
Slope is 5
Step-by-step explanation:
- Step 1: The equation of the line is y - 3 = 5(x - 2). Find the slope.
y - 3 = 5x - 10
Slope intercept form is y = mx + b, where m is the slope.
y = 5x - 10 + 3
y = 5x - 7
m = 5
Based on the graph,
f(x) = 1/2x+3
g(x) = -x+4
so, h(x) = -1/2 x +7
Since h'(x) is the derivative or slope of h(x) and h is a line,
h'(x) = -1/2, Answer C.
Answer:
no
Step-by-step explanation:
subtract 22 by 17
subtract 33 by 22
subtract 46 by 33
you get a different answer every time
Answer:
30
Step-by-step explanation:
We know that population mean μ is 30 and population standard deviation σ is 5.
Further average or mean is computed for all sample means. So, the mean of sampling distribution of mean μxbar is calculated.
The property of sampling distribution is that mean of all possible sample means or mean of of sampling distribution of mean μxbar is equal to the population mean μ.
μxbar=μ=30
μxbar=30.
Thus, the obtained value will be 30.
