How do we write this in scientific notation?

Answer:

The value  is   [tex]n_2  = 317[/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  n  =  73

   The proportion that in favor of raising the tuition is  [tex]\^{p} =  0.37[/tex]

   The standard deviation is  [tex]s_1  = 0.098[/tex]

    The required standard deviation  [tex]s_2  = 0.047[/tex]

Generally the requires standard deviation is mathematically represented as

      [tex]s_2  = s_1 *  \sqrt{\frac{n_1}{n_2} }[/tex]

=>    [tex]\frac{s_2}{s_1}  =  \sqrt{\frac{n_1}{n_2} }[/tex]

=>    [tex]\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2[/tex]

=>     [tex]\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2[/tex]

=>     [tex]\frac{73}{n_2} =0.2300[/tex]

=>     [tex]n_2 =  \frac{73}{0.2300}[/tex]

=>   [tex]n_2  = 317[/tex]

Answer:

An equilateral triangle cross section can be obtained by cutting the cube by a plane defined by the midpoints of the three edges emanating from any one vertex.

Answer:

The answer is C, reflection over the y-axis.

Step-by-step explanation:

It is reflection because everything was flipped over the y-axis.

Given parameters:

Weight of box = 2kg

Average weight of an apple  = 0.25kg

Total weight of box filled with apples  = 12kg

Unknown:

Number of apples packed in each box = ?

Solution:

    Since 1 apple weighs 0,25kg, let us find the weight of the apples in the box

Box + apples  = 12kg

weight of box = 2kg

    Weight of apples  = 12kg - 2kg = 10kg

 So;

          0.25kg is the weight of 1 apple;

            10kg  of apples will equal     [tex]\frac{10}{0.25}[/tex]   = 40 apples

Therefore, 40 apples are packed in the box

Answer:

r=  (10.55−6.20s)

--------------------------

         1.25

​  

Step-by-step explanation:

Using the principle of subject of formula, we make number of pounds of rice, r the subject of the given equation. Hence, the equation would be r = (10.55 - 6.20s)/1.25

Given the expression :

6.20s + 1.25r = 10.55

Isolate 1.25r

1.25r = 10.55 - 6.20s

Divide both sides by 1.25 to isolate r

r = (10.55 - 6.20s)/1.25

Therefore, the required expression would be

r = (10.55 - 6.20s)/1.25

Answer:

x = 19

Step-by-step explanation:

the question tells you that the angle CBD is 90°.

so, that means that angle DBE and angle CBE add up to 90.

using this, you can make the following equation:

2x - 1 + 5x - 42 = 90

2x + 5x + -43 = 90

7x - 43 = 90

add 43 to both sides

7x = 90 + 43

7x = 133

x = 133/7

x = 19

Step-by-step explanation:

Another way to state it is to say that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If you put the two shortest sides end to end, they have to be longer than the longest side to be able to angle up to form a triangle.

Answer:

3. 3, 5, 7

4. 1.1, 2.2, 3.2

5. 13, 5, 12

7. 5, 4, 3

8. 4, 4, 3

Step-by-step explanation:

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Step-by-step explanation:

Answer:

9 is a zero of h(x). C. Correct

Step-by-step explanation:

We want to find the zeros of the function

[tex]h(x) = (x^2 - 81)(x + 4)[/tex]

The zeros are the values of x that make h(x)=0, thus we need to solve the equation:

[tex](x^2- 81)(x + 4)=0[/tex]

Factoring:

[tex](x^2 - 81)=(x-9)(x+9)[/tex]

[tex](x-9)(x+9)(x + 4)=0[/tex]

This equation has 3 solutions:

x=9, x=-9, x=-4

A. 0 is not a zero of h(x). Incorrect

B. 4 is not a zero of h(x). Incorrect

C. 9 is one of the zeros of h(x) calculated above. Correct

D. 81 is not a zero of h(x). Incorrect

C) 9

Step-by-step explanation:

As you can see, the numbers on the side are being multiplied by 2

so the inside of the triangle would be 3 since 3x2=6

Answer:

the answer is c

Step-by-step explanation:

An equilateral triangle has three equal sides. Let's try to first find the actual value of each side of the triangle!

96 inches is the perimeter of the triangle. The triangle has three equal sides. We can find the length of each side by dividing 96 inches by 3!

96 / 3 = 31 inches

The length of each side in the equilateral triangle is 31 inches.

We know that the length of each side is 2x + 6, and we previously found that the length of each side in the equilateral triangle is 31 inches. We are trying to find x, so we can create an equation and isolate x!

31 = 2x + 6

-6    -6

25 = 2x

÷2     ÷2

12.5 = x

Yay, we just found x! That's the answer! Feel free to ask any questions if you need help. I'm not here to judge; I'm here to help. :)
