Rewrite the following equation in standard form.<br><br> y + 2 = -8(x + 6)
crimeas [40]

Answer:

y=-8x-50

Step-by-step explanation:

Standard form or slope intercept form is y=mx+b  

m=slope or (y2-y1/x2-x1) or rise/run

b= y-intercept or where the graph of the equation crosses the y-axis

So we have;

y+2=-8(x+6)

y=-8(x+6)-2

y=-8x-48-2

y=-8x-50

Any questions please feel free to ask. Thanks.

Which expression entered into a graphing calculator will return the probability
kirza4 [7]

Answer:

B. binomcdf(100, 0.5, 35)

Step-by-step explanation:

Binomcdf function:

The binomcdf function has the following syntax:

binomcdf(n,p,a)

In which n is the number of trials, p is the probability of a success in a trial and a is the number of sucesses.

35 or fewer heads come up when flipping a coin 100 times.

100 coins are flipped, which means that n = 100.

Equally as likely to be heads or tails, so p = 0.5

35 or fewer heads, so a = 35.

Then

binomcdf(n,p,a) = binomcdf(100,0.5,35)

The correct answer is given by option B.
