Answer:

B. Step 4 is incorrect , it should be $\frac{10}{8}$

Step-by-step explanation:

6x-1= -2x+9

Step 1

Collect like terms and change signs if you move anything from one side to the other; 6x+2x = 9+1

Step 2: Add like terms on both sides

8x = 10

Step 3: To remain with just x on one side, divide both sides by 8 and it becomes;

$\frac{8x}{8} = \frac{10}{8}$

The two 8s cancel each other and you remain with $x=\frac{10}{8}$

What is the value of x in the equation 2x + 3y = 36, when y = 6?

amm1812

Answer:

Step-by-step explanation:

When plugging 6 in for y, you get

2x + 3(6) = 36

You have to multiply 3 and 6, getting

2x + 18 = 36.

Now, you subtract 18 from both sides to isolate the x variable, getting

2x = 18

Now, you divide 2 from both sides because we want x standing by itself, getting

x = 9

Therefore, your answer is 9.

Hope this helped

ps accepting brainliest ;)

Solve each system of equations algebraically y= x-6 y= 2x

lbvjy [14]

Answer: x = -6

Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.

y = x - 6

y = 2x

2x = x - 6 (substitute the y value into the equation)

1x = -6 (subtract x on each side)

x = -6 (1x is basically saying x so you do not need to divide)

Answer:

To be able to approximate the sampling distribution with a normal model, it is needed that $np \geq 10$ and $n(1-p) \geq 10$ , and both conditions are satisfied in this problem.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they will make payments on time, or they won't. The probability of a person making the payment on time is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The sampling distribution can be approximated to a normal model if:

$np \geq 10$ and $n(1-p) \geq 10$

Based on past experience, a bank believes that 8.9 % of the people who receive loans will not make payments on time.

This means that $p = 0.089$

The bank has recently approved 220 loans.

This means that $n = 220$

What must be true to be able to approximate the sampling distribution with a normal model?

$np = 220*0.089 = 19.58 \geq 10$

$n(1-p) = 220*0.911 = 200.42 \geq 10$

To be able to approximate the sampling distribution with a normal model, it is needed that $np \geq 10$ and $n(1-p) \geq 10$ , and both conditions are satisfied in this problem.
