Answer:

34.93

Step-by-step explanation:

Ok, so using the formula for a trapezoid, you would get that Jim's garden's area is equal to 135.

Since each grass bag can cover 20m of the garden,

135/20=6.75

You would need seven bags because you can't buy 6.75 bags at a store.

Since each bag of grass seed is 4.99, 7*4.99 = 34.93.

I'm doing this in dollars, so I'm assuming that one pound is 100 cents or something like that.

What is the slope?<br><br> A) 3/7<br> B) 7/3<br> C) -3/7<br> D) -7/3

Brut [27]

Answer:

B) 7/3

Step-by-step explanation:

To find the slope of a line using a graph, locate two points. In this example, the points are (0, -2) and (3, 5).

Then, find the distance between the two points. To do so in this example, find the difference between 0 and 3, and -2 and 5.

3 - 0 = 3

5 - (-2) = 7

Since we're dealing with slope, the answer will be in y/x form. 7 is the distance between the y-coordinates and 3 is the difference between the x-coordinates, the answer is 7/3.

distribution has a mean if 18 standard deviation of 4 a value of 24 is how many standard deviations away from the mean

liraira [26]

A value of 24 is 2.5 standard deviations away from the mean

<h3>'How to determine the number of standard deviations away from the mean?</h3>

The given parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

Let the number of standard deviations away from the mean be x.

The value of x is calculated using

Mean + Standard deviation * x = Value

Substitute the known values in the above equation

18 + 4 * x = 24

Subtract 18 from both sides of the equation

4 * x = 6

Divide both sides of the equation by 4

x = 1.5

Hence, a value of 24 is 2.5 standard deviations away from the mean

So, the complete parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

24 is 2.5 standard deviations away from the mean
