Rasek [7]

Answer:

1200

Step-by-step explanation:

Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute.  Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.

(I might get this wrong, so like yeah.)

Draw the standard normal distribution curve
kirza4 [7]

Standard Normal Distribution. As discussed in the introductory section, normal distributions do not necessarily have the same means and standard deviations. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution.

Which statement best describes the triangle formed by joining the points A(-3,6),B(-11,2),C(-4,-2)
Vikki [24]

Answer:

Isosceles triangle

Step-by-step explanation:

Length of side AB = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

                              = \sqrt{(-11+3)^2+(2-6)^2}

                              = \sqrt{64+16}

                              = \sqrt{80}

                              = 4\sqrt{5}

Length of BC = \sqrt{(-4+11)^2+(-2-2)^2}

                      = \sqrt{49+16}

                      = \sqrt{65}

Length of AC = \sqrt{(-3+4)^2+(6+2)^2}

                      = \sqrt{1+64}

                      = \sqrt{65}

Since, AC = BC, ΔABC will be an isosceles triangle.
