What is 3/8 divided by 2

Answers

Hello.

3/8 divided by 2 can be put into the equation 3/8 ÷ 2/1.

You can't divide fractions, so you flip the divisor's fraction, then switch the equation to multiplication. The equation is now 3/8 × 1/2. Multiply across

--> 3 * 1

________

--> 8 * 2

Finishing the equations, we are left with 3/16. This cannot be reduced, so the final answer is 3/16

Answers

Answer:

H0: sigma=12

H1:sigma≠12

This hypothesis test is a two tailed test.

Step-by-step explanation:

The null value described in the statement is 12 mg. So, the null hypothesis would be sigma=12. As the statement states that whether there is sufficient evidence to conclude that standard deviation differs from 12 mg, so the alternative hypothesis would be sigma ≠12. The alternative hypothesis contains inequality sign so, the hypothesis test is a two tailed test.

27. Give the perimeter of the rectangle below in
simplest form.

Answers

Answer:

The permeter will be 26 units

Step-by-step explanation:

First to find this you need to know what the value of x is to do this I will use the equation 3x - 7 = x + 2

1. add seven to both sides leaving 3x = x + 9

2. Then subtract the 1x from both sides leaving 2x = 9

3. Then divide 9 by 2 which will be 4.5, x = 4.5

Then just plug 4.5 into each x value 4.5 + 2 and 3(4.5) - 7

1. 4.5 + 2 = 6.5

2. 3(4.5) - 7              13.5 - 7 = 6.5

The perimeter of the rectangle below in simplest form will be 4(x - 3).

Length of the rectangle = 3x - 7

Width of the rectangle = x+2

The perimeter of a rectangle is given as 2(length + width). The perimeter of the rectangle given will then be:

= 2(length + width)

= 2(3x - 7) + 2(x + 2)

= 6x - 14 + 2x + 4

= 4x - 12 = 4(x - 3)

Therefore, the perimeter of the rectangle in simplest form will be 4(x - 3).

The solution to an inequality is graphed on the number line. What is another way to represent this solution set? O {x | X 4.5) O x | x2 4.5) 5 -3 -2 -1 0 1 2 3 4 5​

Answers

Answer: Choice B  [tex]\{x | \ x \le 4.5\}[/tex]

=============================================

Explanation:

The endpoint is at 4.5 and this endpoint is a filled in circle. So we'll have "or equal to" as part of the inequality sign. This is because we are including the endpoint as part of the shaded solution region.

The other part of the inequality sign is "less than" because the shading is to the left of the endpoint. Any point in the shaded region is less than 4.5, or it could be equal to 4.5

Put another way: x is either 4.5 or smaller

We write that as [tex]x \le 4.5[/tex] which is read out as "x is less than or equal to 4.5"

Surrounding this in curly braces tells the reader we're dealing with a set of values. The first part "x |" means "x such that"

All together we end up with the answer [tex]\{x| \ x \le 4.5\}[/tex] which translates to "x such that x is less than or equal to 4.5"

Step-by-step explanation:

If A is the mipoint of BC, then AB is half of BC.

AB = BC / 2

16x − 4 = 3x + 8

13x = 12

The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24? y – 20 y – 14 y – 8 y – 6

Answers

Answer:

y - 6

Step-by-step explanation:

Given

y² - 10y + 24

Consider the factors of the constant term (+ 24) which sum to give the coefficient of the y- term (- 10)

The factors are - 4 and - 6, since

- 4 × - 6 = + 24 and - 4 - 6 = - 10, thus

y² - 10y + 24 = (y - 4)(y - 6)

Thus the other factor is (y - 6)

(y - 4) and ( y - 6 ) are the factors of the quadratic equation

What do you mean by quadratic equation?

The equation ax2 + bx + c=0 in one variable, with a 0, is known as a quadratic equation. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.The answer could be simple or complicated.

The roots of the quadratic equations are

x = [-b ± √ (b² - 4ac)] / ( 2a ) ( 2a )

Since (b2 - 4ac) is positive, we have two real solutions where (b2 - 4ac) is the discriminant.

When the discriminant is 0, there is just one viable option (both answers are the same)

In the case of a negative discriminant, two complicated solutions are obtained.

Let the quadratic equation be expressed as A given the data.

Right now, A is valued at

y² - 10y + 24   be equation (1)

The quadratic equations' roots are

y = [ -b ± √ ( b^2 - 4ac ) ] / ( 2a )

y = 10 ± √ ( 100 ) - ( 4 ( 24 ) ) / 2

y = ( 10 ± √4 ) / 2

y = ( 10 ± 2 ) / 2

As a result, y has two values of 10 + 2 / 2 and 6

And , y = (10 - 2) / 2 y = 4

In addition, the variables in the equation are

( y - 4 ) ( y - 6 ) = y² - 10y + 24

The quadratic equation is therefore resolved.

The first number (-5) is on the x, or horizontal axis, and the second number (3) is on the y, or vertical axis. Therefore, starting at (0,0) (the origin), you would count -5 points to the left to get to -5 on the x axis, and then you would count 3 points up to get to 3 on the y axis.
