Prob(a head on 1 toss) = 1/2

So probability of 8 heads in a row = (1/2)^8 = 1/256 or close to 0.391%

What is the slope of a line that is perpendicular to a line whose equation is 3y=−4x+2 ?

vova2212 [387]

we know that

if two lines are perpendicular, then the product of their slopes is equal to minus one

$m1*m2=-1$

Step 1

Find the slope of the given line

we have

$3y=-4x+2$

Solve for y

Divide by $3$ both sides

$3y/3=(-4x+2)/3$

$y=-\frac{4}{3}x+ \frac{2}{3}$

the slope of the given line is $m1=-\frac{4}{3}$

Step 2

Find the slope of a line that is perpendicular to the given line

we have

$m1=-\frac{4}{3}$

$m1*m2=-1$

$m2=-1/m1$

substitute the value of m1

$m2=-1/(-4/3)=\frac{3}{4}$

therefore

the answer is

the slope is $\frac{3}{4}$

likoan [24]

Answer:

A The data is proportional and the unit rate per package is $8 This is because y= 8x

Step-by-step explanation:

/y relationship is no of packages = 1 x/ = total cost to ship = 8 = 8/1 = 16/2 = 24/3 = 32/4 means they are all proportional to 8/1 = 8 y = 8x see graph attached

)The histogram shows the number of gold medals won by different numbers of students at an art competition. Which of the followin

Mnenie [13.5K]

Answer:

Eight students won 6, 7, or 8 gold medals.

Step-by-step explanation:

We see that the third bin is labelled 6 - 8. Since this is on the horizontal, or x, axis, this means that the students in this "bin" have won 6 - 8 medals, which is the same as saying winning 6, 7, or 8 medals.

Because this "bin" goes to 8, that means that there are 8 students who earned this many medals.

Thus, the answer is D.

Hope this helps!
