Waht number is 120% of 140

The values of the x in the given equation are x = 6.46 and x = -0.46

From the question, we are to solve the equation for x

The given equation is

(x+3)² -10 = 2

First, add 10 to both sides of the equation

(x+3)² -10 +10 = 2 +10

(x+3)²  = 12

Now, take the square root of both sides to get

x + 3 = ±√12

∴ x = 3 ± √12

x = 3+√12 OR 3-√12

x = 3 + 3.46 OR 3 - 3.46

x = 6.46 OR -0.46

Hence, the values of the x in the given equation are x = 6.46 and x = -0.46

Here null hypothesis is rejected in this problem.

According to the statement

We have a given that the evidence at alpha level is 0.02, ANd the sample size n is 67. And mean time equal to 330 minutes and the variance that is the sigma square is equal to 529 point.

And We have to make the decision to reject or feel fail to reject the null hypothesis to solve this problem.

Firstly we solve alternative and null hypothesis

So, the null hypothesis h naught will be that mu is less than equal to 327 point and alternative hypothesis ha will be.

That mu is greater than 327 point now. This alternative hypothesis is claimed.

Next we will find the value of s which is given by sigma divided by under root n.

So, s = 67/ (529)^1/2

s = 2.8099.

Now we find the value of Z

So, Z = 327 - 330 / 2.8099

Z = 1.0677

Now the critical value of z is 2.05

Critical, we can say fail to reject the null hypothesis, and this is the result from the null hypothesis test.

With this test, we can conclude that the the data do not support that. There is evidence at 0.02 level that the drug stays in the system for more than 327 minutes. So this is the conclusion for the test for the hypothesis test and the answer to the problem.

So, Here null hypothesis is rejected in this problem.

Answer:

f(g(2)) = 50

Step-by-step explanation:

evaluate g(2) then substitute the result obtained into f(x)

g(2) = 3(2) - 2 = 6 - 2 = 4 , then

f(4) = 2(4 + 1)² = 2(5)² = 2(25) = 50

Answer:

f[g(2)] = 50

Step-by-step explanation:

Given functions:

[tex]f(x)=2(x+1)^2[/tex]

[tex]g(x)=3x-2[/tex]

We are asked to determine f[g(2)], which is known as a composite function. When solving composite functions, you always work inside out.

Step 1: Find the value of g(2) by substituting 2 for x in function g(x).

[tex]\implies g(2)=3(2)-2[/tex]

[tex]\\\implies g(2)=6-2\Rightarrow g(2)=\boxed{4}[/tex]

Step 2: Substitute the found value into the composite function.

[tex]\\\implies f[g(2)]= 2(4+1)^2[/tex]

[tex]\implies f[g(2)] = 2(5)^2 \Rightarrow 2(25) \Rightarrow \boxed{50}[/tex]

Hence, the value of the composite function f[g(2)] is 50.

The solution set of the equation x^2 + 2x - 48 = 0 is x = -1 ± 7

The equation is given as:

x^2 + 2x - 48 = 0

A quadratic equation is represented as:

ax^2 + bx + c = 0

By comparing both equations, we have

a = 1, b = 2 and c = -48

The solution of the quadratic equation is then calculated using

x = (-b ± √(b^2 - 4ac))/2a

Substitute values for a, b and c in the above equation

x = (-2 ± √(2^2 - 4 * 1 * -48))/2 * 1

This gives

x = (-2 ± √196)/2

Evaluate the square root of 196

x = (-2 ± 14)/2

Each angle in an equilateral triangle is 60 degrees, so we have:

10x + 20 = 60

10x = 40

x = 4.

Answer:

X = 4

Step-by-step explanation:

The angles of a triangle add up to 180 degrees and this is an equilateral triangle which means that all the angles are the same. which means you set up the equation:

10x + 20 + 10x + 20 + 10x + 20 = 180

Simplify: 30x + 60 = 180

                        - 60   - 60

You have : 30x = 120

(Divide by 30)

You end up with: X = 4

The equation representing the given situation is, 250 = 70x + 35, where x is the number of cars washed by the company.

In the question, we are given that Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in cleaning supplies per car.

We are asked to represent the situation with an equation.

We assume the number of cars washed by the company to be x.

Charge for washing 1 car = $75.00.

Cost for cleaning supplies for 1 car = $5.00.

Thus the profit on the wash of 1 car = $75.00 - $5.00 = $70.00.

The total profit received by the company, on washing x number of cars = $70x.

The tips received = $35.00.

Thus, the total profit of the company = $(70x + 35).

But, the total profit is given to be $250.00.

Thus, we get an equation, 250 = 70x + 35.

Thus, the equation representing the given situation is, 250 = 70x + 35, where x is the number of cars washed by the company.
