We use y=mx+c we know that c= 4 A’s this is the y intercept . Next we need to work out the gradient(m). For every two squares along we go three squares up. This means are gradient is 1.5. Finally we input are values into the equation y=1.5x+4

(left to right)

4²-(3.1+6.4)+4.5

According to PEMDAS, we will do what is inside the parenthesis.

3.1+6.4 = 9.5

4²-9.5+4.5

Then we do figure out the exponent.

4² = (4)(4) = 16

16-9.5+4.5

Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.

16-9.5 = 6.5

6.5 + 4.5 = 11

11 is your answer :)

A brand new car is $22,000 and its value depreciates 7% each year. How many years will it take for your car to be $10,000? Round

.200 because 22,000 % by 7 is 1540 which you divide by 10,000

A coin is tossed seven times and the sequence of heads and tails is observed. what is the number of different outcomes having ex

Margaret [11]

You could make a tree diagram
H T ← 1st toss

H T H T ← 2nd toss

H T H T H T H T ← 3rd toss
etc ,,, then count the combination of favorable outcomes

Using a calculator:
Total number of outcomes is $2^{7}$ = 128
Probability of getting exactly 3 heads is found using the follow calculator feature: binompdf(7, 0.5, 3)

ANSWER: Typed into the calculator as follows binompdf(7,0.5,3)×128 = 35

Lee watches TV for 2 hours per day. During that time, the TV consumes 150 watts per hour. Electricity costs (15 cents)/(1 kilowa

shutvik [7]

So electricity costs 15cents every 1,000 watts used, and if he watches tv for 2hrs every day for a month that’s 60 hours (2*30) And every hour he watches tv it’s 150 watts. They want you to do the 60 hrs times 150watts which is 9,000 (amount of watts he uses in the month) and remember 1,000 watts is 15cents
