Answer:
Step-by-step explanation:
Subtract 7x from both sides to isolate y
Divide both sides by -4 to isolate y
Simplify and flip the 
because you are dividing by a negative number
Finito.
Answer:
<h3>-10⇜</h3>
Step-by-step explanation:
AB=-6×-5÷-1×3
AB= 30÷-3
<h3>AB= -10⇚</h3>
Sometimes because sometime when you turn a square 45° it is a rhombus but other times a rhombus could have angles other than all 90°
There is a difference between the expected value and the value you get when you actually try this experiment
The value you would get if you actually tried the experiment
You would expect to get 3/6 for the 2. This means that when you throw the die any number of times, you will get a 2 about 1/2 the time. If you throw the die 1500 times 750 of them should be a 2.
You would expect to get 2/6 for the 1. When you throw the die any number of times, you would expect to get a "1" 1 out of 3 times. If you throw the die 3000 times, 1000 of them should be a 1.
You would expect to get 1/6 for the blank. This means that for any number of throws 1 out of every 6 should come up blank. In other words, if you divided the number of throws by 6, you should get that many blanks.
The actual value is as above
The expected value in probability is
2 * 1/2 = 1
1 * 1/3 = 0.3333
0 * 1/6 = 0
The expected value = 1.33 just as you said.
Answer:
-6
Step-by-step explanation:
Hello!
Since we are finding f(-1) we put -1 in for x
2(-1)^2 + 8(-1)
Follow PEMDAS
2 * 1 + 8(-1)
2 * 1 + -8
2 + -8 = -6
The answer is -6
Hope this helps!
