Answer:

Step-by-step explanation:

For this you will start at negative 3 then go up 5 spaces and to the right 4 times. Once you run out of space in one direction go in the opposite doing the opposite steps. Going down 5 times and to the left 4 times. If you need any more help with these, I'll be glad to help as I am learning these in class right now. The way to determine which way your going is on the slope. The slope in those equations is the number before x. The coefficient. When the numerator(y axis) is positive, that means you go up on the graph by the number shown. If its a negative go down. If the denominator (x-axis) is a positive that means you go to the right by the number shown. If it's a negative you go to the right. The number all the way on the right, in this case the -3, that is the y intercept.

Monica [59]

Answer:

6(4)(5) = 120 units³

Step-by-step explanation:

From the options, I deduced that the prism is a rectangular prism. Then, its volume is computed as follows:

Volume = length*width*height

where length, width and height are 6, 4 and 5 length unit, respectively. Therefore, its volume is:

Volume = 6*4*5 = 120 cubic unit

At a certain bakery, the price of each doughnut is $1.50. Let the random variable D represent the number of doughnuts a typical
Solnce55 [7]

Using <em>statistical concepts</em>, it is found that the standard deviation of the probability distribution is of

s = 1.5(1.9) = 2.85

When a constant is multiplied to each data in a variable, both the <u>mean and the standard deviation</u> are multiplied by the constant.

In this problem, the standard deviation, which is the square root of the variance, is of:

\sigma = \sqrt{\sigma^2} = \sqrt{3.6} = 1.9

The price of each is of $1.5, hence:

s = 1.5(1.9) = 2.85
