Answer:

3

Step-by-step explanation:

Answer:

A is the correct answer.

Step-by-step explanation:

The formula for the area of a triangle is A = 1/2 b x h

The base in this triangle is 6 and the height is 4 so 6 x 4 = 24.

Now we divide 24 by 2 which gives us 12 square centimeters.

Answer: A. 12 square centimeters

Step-by-step explanation:

The area of a triangle is (1/2)bh because any triangle is half of a square (square formula = bh).

1/2bh --> 1/2  * 6 * 4 --> 12 square centimeters

Hope this helps! Good Luck :)

Step-by-step explanation:

the area of square is 10²=100

Area of a circle is πr²=π(10/2)²=25π

100-25π=100-25*3.14=100-78.5=21.5

Step-by-step explanation:

Multiply 10 by 10, then find the area of the circle (78.54) then subtract, 100-78.54= 21.46. Then round. So its A. 21.5 meters squared

Answer:

h = 12 inches

Step-by-step explanation:

The volume is  given by

V = Bh  where B is the area of the base and h is the height

Substituting V = 1080 and B = 90

1080 = 90h

Divide each side by 90

1080/90 = 90h/90

12 = h

Answer:

It's D.

Step-by-step explanation:

The 1/2 stretches the graph horizontally of x^2 by a factor 1/2.

Option-D will represent the required graph of the function [tex]g(x) = \frac{1}{2}f(x)[/tex].

"A function is defined as a relation between a set of inputs having one output each."

The given function:

[tex]f(x) = x^{2}[/tex]

Therefore the required function is:

[tex]g(x)\\= \frac{1}{2}f(x)\\= \frac{1}{2}x^{2}[/tex]

By putting the values of 'x' as -2, -1, 0, 1, 2 etc. we get:

[tex]g(-2) = (-2)^{2} = 4\\ g(-1) = (-1)^{2} = 1\\ g(0) = (0)^{2} = 0\\ g(1) = (1)^{2} = 1\\ g(2) = (2)^{2} = 4[/tex]

By plotting this value, we get option-D is the graph that represents the function g(x).

Answer:

The answer would be D.

Step-by-step explanation:

All you have to do is combine like terms.

Pretend that the parenthesis aren't there. 13x + 9y + 38x + 33y.

When you combine like terms, you add or subtract the terms that have the same variable attached.

13x + 38x = 51x.

9y + 33y = 42y

51x + 42y.

Answer:

1.44

Step-by-step explanation:

No. of warp coils manufactured in one group = 36

defect rate = 4%

That is 4 out of every 100 warp coil is defective

No. of defective warp coil in one group = 4% of warp coil in one group

                                                             = 4% of 36 =4/100 *36

                                                             = 1.44

Thus, there are 1.44 defective coil in each group.

Since, mean number is average number of defect.

So if each group has 1.44 defective coils then mean for all the group will remain same i.e 1.44

Answer:

The sample proportion is 0.253.

Step-by-step explanation:

We are given that a 90% confidence interval for a proportion is found to be (0.22, 0.28).

Firstly, as we know that the confidence interval for sample proportion is calculated as;

90% confidence interval = Sample proportion [tex]\pm[/tex] Margin of Error

Here, let [tex]\hat p[/tex] = sample proportion

Also, the level of significance = 1 - 0.90 = 0.10 or 10%

And, the critical value of z at 5% (two-sided) level of significance is 1.645.

So, 90% confidence interval =  [tex]\hat p \pm 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]

           (0.22 , 0.28)    =   [tex]\hat p \pm 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]

This means;  

          0.22  =  [tex]\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]  -------------- [Equation 1]

          0.28  =  [tex]\hat p + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]  -------------- [Equation 2]

From equation 1 and 2, we get;

           [tex]0.22 + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }= 0.28 - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]

           [tex]1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} } + 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }= 0.28 -0.22[/tex]

             [tex]2 \times 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} } =0.06[/tex]

                 [tex]\sqrt{\frac{\hat p(1-\hat p)}{n} } =\frac{0.06}{2 \times 1.645}[/tex]

                  [tex]\sqrt{\frac{\hat p(1-\hat p)}{n} } =0.02[/tex]

Now, squaring both sides, we get;

                    [tex]{\frac{\hat p(1-\hat p)}{n} } =0.0004[/tex]

                      [tex]n ={\frac{\hat p(1-\hat p)}{0.0004} }[/tex]

Now, putting value of n in equation 1, we get;

                    0.22  =  [tex]\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }[/tex]  

                    0.22  =  [tex]\hat p - 1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{\hat p(1-\hat p)}\times 0.0004 }[/tex]

                    0.22  =  [tex]\hat p - 1.645 \times \sqrt{ 0.0004 }[/tex]

                    0.22  =  [tex]\hat p -( 1.645 \times 0.02)[/tex]

                    0.22  =  [tex]\hat p -0.033[/tex]

                      [tex]\hat p = 0.22 + 0.033[/tex] = 0.253

Therefore, the sample proportion  [tex]\hat p[/tex] is 0.253.

Answer:

a = 80

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + 60^2 = 100 ^2

a^2 +3600=10000

Subtract 3600 from each side

a^2 = 10000-3600

a^2 =6400

Take the square root of each side

a = sqrt(6400)

a = 80

The volume of a cylinder is 40 ft which expression represents the volume of a Cone with the same base and height as the cylinder?

3(40) ft³

3(1/40) ft³

1/3(40)ft³

1/3(40²) ft³

Answer:

The expression  that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³

Step-by-step explanation:

To find the expression that represents  the volume of a cone with the same height and base as the cylinder, we will follow the steps below:

First write down the formula for calculating volume of a cone   and volume of a cylinder

volume of a cone = [tex]\frac{1}{3}[/tex] πr²h

volume of a cylinder = πr²h

If the base are the same, this implies they have the same radius,  and from the question, it states that they have the same height, hence;

volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

from the question, the volume of the cylinder is 40 ft³

volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

                              = [tex]\frac{1}{3}[/tex] (40) ft³

volume of a cone =  [tex]\frac{1}{3}[/tex] (40) ft³

Therefore the expression  that represents the volume of a cone is [tex]\frac{1}{3}[/tex] (40) ft³
