Answer:

x = -11

Step-by-step explanation:

Hello There!

create an equation

x + 51 + 60 + 80 = 180

combine like terms

51 + 60 + 80 = 191

x + 191 = 180

subtract 191 from each side

180 - 191 = -11

we're left with

x = -11

If you flip two coins 96 times what is the best prediction for the number of times they would both land on tails

emmainna [20.7K]

Flipping two coins gives four possibilities: HH, HT, TH, TT

So P(TT)=1/4

So we'd expect a quarter of the trials to be two tails.

$\frac 1 4 \times 96 = 24$ trials expected to be two tails.

For the graph x = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an

scoray [572]

Lines that are perpendicular to another line has an opposite reciprocal slope. (opposite meaning to negate the number).
Lines that are parallel have the same slope.

But the line you provided is a vertical line, and vertical lines are undefined. There is no possible perpendicular or parallel line. Maybe you gave the wrong equation and didn't put it in <em>y=mx+b</em> form. If so, you can correct it in the comments, and if not, that's you answer!
