kolbaska11 [484]

Answer:

Step-by-step explanation:

<h3>$40000 = amount after 8 years </h3><h3>time = 8 years </h3><h3>interest = 3%</h3><h3>principle amount = ?? ( p )</h3><h3>$40000 = (( p ) × 3 × 8 )÷100</h3><h3>p = (40000 × 100) ÷ ( 3 × 8 )</h3><h3>p = $166666.67</h3>

The diagram represents a triangle that is reduced by a scale factor of 0.4.

NARA [144]

Answer:the answer would be 8.

Step-by-step explanation:

If you look at the reduced triangle, the height is 2. Therefore you would have to multiply by 4 instead of 0.4 even if the scale factor is 0.4. The reason is, you are enlarging the triangle to find the bigger triangle. If you did 0.4 times 2 you would get 0.8. But that wouldn’t make any sense if you said that that was the height of the ENLARGED triangle.

Select all of the true statements about the standard deviation of a quantitative variable. 1. Standard deviation is resistive to

andrezito [222]

Answer:

Considering the first statement

Standard deviation is resistive to unusual values

This statement is false because standard deviation is the numeric measure of deviation of the each observation from the mean

Considering the second statement

The standard deviation of a set of values is equal to 0 if and only if all of the values are the same.

This statement is true because standard deviation is the numeric measure of deviation of the each observation from the mean.

Considering the third statement

Standard deviation is never negative.

This statement is true because standard deviation is the numeric measure of deviation of the each observation from the mean.

Considering the fourth statement

Changing the units of a set of values (e.g., converting from inches to feet) does not affect its standard deviation

This statement is false because standard deviation is the numeric measure of deviation of the each observation from the mean

Considering the fifth statement

If a set of values has a mean of 0 and a standard deviation that is not 0, then adding a new data point with a value of 0 will have no effect on the standard deviation.

This statement is false because , let take an example

x -4 - 3 0 3 4

Generally the mean is mathematically evaluated as

$\= x = \frac{\sum x_i }{n}$
