If the spinner is spun another 1000 times about how many times would you expect it to land on blue? Frequency of blue is 45

450 considering Blue appears 45 times in 100 spins.

Step-by-step explanation:

Let us assume that frequency of Blue is 45 times in 100 spins.

So we have to calculate the number of times the spinner lands on blue in 1000  spins.

It simply can be calculated as

Expected number of landing on blue:

Expected frequency = probability × number of trials

= (45/100)×1000

= 450 times

So, Expected number of landing on blue = 450

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
