A segment has endpoints (-9,-20) and (14,12). What is the midpoint of this segment

Match each table of data below with the most appropriate graph and briefly explain why it matches the data

Stells [14]

Answer:

Table a match with Graph 3

Table b match with Graph 2

Table c match with Graph 4

Step-by-step explanation:

Table a

Time is plotted on x - axis and Temp on y axis

From table a we can see that the y values(temp) decrease with increasing time. The only graph that has a decreasing trend is Graph 3

Table b

Time plotted on x axis, cost on y axis

Looking at the values we see that they are almost linear except for 2 values at x = 2 and 2.5 and at y = 5 and 5.3.

Ignoring values 2.5 and 5.3 we see a linear fit with a slope of 20. This means either graph 1 or graph 2

However, the graph passes through (0,0) and this is not a set of values in the table. That leaves graph 2

Table c

Months plotted on x axis and length of fetus on the y axis

We can see that the y values (the length) increases slowly at lower values of x(x=1 and x=2) and then increase rapidly at the mid values(x = 2 thru 6) and then slows down between months 6 and 9. Only Graph 4 fits this pattern

Find the distance between (5, 9) & (-7, -7). Round to the nearest tenth.

coldgirl [10]

Distance equals end minus start

(-7,-7)-(5,9)=
(-7-5,-7-9)=(-12,-16)

(-12,-16) gives us the distance point coordinates. Now to find the magnitude we can take sqrt((-12)^2+(-16)^2)=20

So the distance between the two points is 20

I hope this helps

Which graph shows the solution to the equation 4x-4=4?

Mama L [17]

Answer:

A

Step-by-step explanation:

y = 4x - 4 is a line with y-intercept -4 and slope 1. Both graphs A and C show that line in blue.

y = 4 is a horizontal line through y = 4. Graph A shows that line.

Answer: A

A theater group holds a fund-raiser. It sells 100 raffle tickets for $7 apiece. Suppose you purchase four tickets. The prize is

lys-0071 [83]

Answer:

Check Explanation

Step-by-step explanation:

The random variable X is the possible net amount that leaves or enters one's hands. It is the amount of winnings!

X can take on value of -($7 × 4) = -$28

(That is, none of the four raffle tickets bought is picked to win)

X can also take on value of [$150 - ($7 × 4)] = $122

(That is, one of the four raffle tickets bought is picked to win)

For the probability distribution function, we find the probabilities of the different amount of winnings.

First of, probability of losing = (96/100) = 0.96

Then, probability of winning = (4/100) = 0.04

Probability density distribution is then given as

X | probability

-$28 | 0.96

$122 | 0.04

To go a step further, expected winnings would be

E(X) = Σ xᵢpᵢ = (-28)(0.96) + (122)(0.04)

= -26.88 + 4.88 = -$22

The expected winnings show that this is not a risk worth taking.

Hope this Helps!!!
