dsp73

Answer:

Step-by-step explanation:

Given that you and a friend play a game where you each toss a balanced coin.

If the upper faces on the coins are both tails, you win $1;

if the faces are both heads, you win $2;

if the coins do not match (one shows a head, the other a tail), you lose $1 (win (−$1)).

Let Y be the amount won

Then Y can take values as 1,2 and -1

P(Y=1) =P(TT) = 0.25\\P(Y=2) = P(HH) = 0.25\\P(Y=-1) = P(HT)+P(TH) = 0.5

The above is the probability distribution for Y.

June is driving from brookline, massachusetts to brooklyn, new york. The cities are 200 miles apart. Pretend june lives in a wor
dolphi86 [110]

The formula that describes this function is c = 50t + 200

<h3>What is a Linear equation</h3>

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change  and b is the y intercept.

Let c represent the distance june has traveled after time t.

Since the cities are 200 miles apart, hence b = 200. Also the spoeed is 50 mph, hence m = 50:

c = 50t + 200

The formula that describes this function is c = 50t + 200

Help with math plz! Giving brainlist

First one, 

You add -7 to the pattern. 

5, -2, -9, -16.
50 times is going to be -350. But it starts at 5, so you add 5 to -350... so it should be -345?

second if the top is 7.1 and the bottom is 3.9. The average is (7.1+3.9)/2.
11/2 = 5.5

Add 10 to each number in the pattern.
-7, 3, 13, 23. 
110 times should be 1100, but it starts at -7, so you add -7 to 1100. 1093. :)
