Answer:

3. Standard deviation is the square root of the variance.

4. Standard deviation is useful because it has the same units as the underlying data.

Step-by-step explanation:

3. In statistics, the dispersion in a given data with respect to its mean distribution can be determined or measured by standard deviation and variance. The standard deviation of a distribution can also be determined as the square root of variance.

4. Standard deviation is measured in the same units as that of the original data. Thus it has the same units as the underlying data.

A farmer uses 1/3 of his land to plant cassava, 2/5 of the remaining and to plant maize and the rest vegetables .if vegetables c
mihalych1998 [28]
Add both the known values of plants together
1/3 + 2/5
Cross multiply to add the fractions together
This leaves with 11/15
This means the remaining vegetables cover 4/15s of the farmers land
This means that 10 acres is 4/15 of the farmers total land.
Divide 10 acres by 4/15 to find the total land of the farmer
This means the farmers total land is an area of 37.5 acres

The answer is B 

Reason Being is because you would combine (4x) and (-10x) which would give you -6x.

After combining those you would combine (7) and (15) which would give you 22.

Therefore, your answer is (22-6x)

What is the slope of y=-4x-3y=−4x−3y, equals, minus, 4, x, minus, 3?
stepan [7]

Answer:

-4

Step-by-step explanation:

Given:

y = -4x - 3

Required:

Slope of the line

SOLUTION:

The equation of the line, y = -4x - 3, is given in the slope-intercept form, which is y = mx + b.

Where, m is the slope, and b is the y-intercept.

Therefore, the slope (m) of the line, y = -4x - 3 is -4.

m = -4
