Let's calculate the value of c using Pythagoras theorem ~

[tex]\qquad \sf  \dashrightarrow \: c {}^{2} = a {}^{2} + {b}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: 40 {}^{2} = {24}^{2} + {b}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: b² = \sqrt{40² - 24²} [/tex]

[tex]\qquad \sf  \dashrightarrow \: b= \sqrt{1600-576} [/tex]

[tex] {\qquad \sf  \dashrightarrow \: b= \sqrt{1024}} [/tex]

[tex]\qquad \sf  \dashrightarrow \: b = 32 \: units[/tex]

The length of "b"

[tex] {c}^{2} = {a}^{2} - {b}^{2} [/tex]

[tex] {b}^{2} = {40}^{2} - {24}^{2} [/tex]

[tex]b = 1024[/tex]

[tex]b = \sqrt{1024} [/tex]

[tex]b = 32[/tex]

Hence, the length of "b" is 32.

Step-by-step explanation:

Remark

a is one part of the cosine function. It is termed the adjacent side. The given number (12) is the hypotenuse of a right triangle. The reference angle is given as 25. You have all you need to solve for a

Givens

<B = 25o

AB = 12

a = a

Equation

Cos(B) = adjacent side / hypotenuse

Solution

Cos(25) = adjacent side / 12               Multiply both sides by 12

12*cos(25) = adjacent side

cos(25) = 0.90631

12*0.906331 = adjacent side

10.87 = adjacent side

Area: 16.65m^2 (^2 means to the power of 2 exponent, or squared)

Perimeter: 26.3 m

Step-by-step explanation:

Triangle Area formula: bh/2

Plug it in: (7.4)(4.5)/2=16.65

Perimeter: Add the sides

12.6+7.4+6.3=26.3

Answer:

Step-by-step explanation:

Remark

Here are the formulas for what you are asking for.

P = s1 + s2 + s3

Area = height * base / 2

Givens

s1 = 12.6

s2 = 6.3

s3 = 7.4

height = 4.5

base = 7.4

The area is just slightly different than it normally is. The reason is the height. It is not directly connected to the base. The construction is called the base extended.  See the givens for what that is.

Solution

Perimeter

P = s1 + s2 + s3                        Substitute givens into the formula

P = 12.6+6.3 + 7.4

p = 26.3

Area

Area = (B * H)/ 2

Area = 7.4 *4.5 / 2

Area = 16.65

Step-by-step explanation:

For very 9 gallons of paint, it needs 7 gallons of yellow.

If the height of the frustum of the cone is 10 cm. Then the volume of this cup will be 47 milliliters.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A small plastic vessel has the shape of a truncated cone as shown. A cubic centimeter is the same as a milliliter.

Then the volume of this cup to the nearest milliliter will be

The volume is given as

[tex]\rm V = \dfrac{1}{3} \pi (r_2^2 - r_1^2) h[/tex]

We have

Height (h) = 10 cm = 0.1 m

Radius (r₁) = 3.2 cm = 0.032 m

Radius (r₂) = 2.4 cm = 0.024 m

Then the volume will be

[tex]\rm V = \dfrac{1}{3} \pi (0.032^2 - 0.024^2) \times 0.1\\\\\rm V = 4.7 \times 10^{-5} \ \ m^3[/tex]

Then the conversion of m³ to milliliters will be

4.7 × 10⁻⁵ m³ = 4.7 × 10⁻⁵ × 10⁶ millileters

4.7 × 10⁻⁵ m³ = 47 milliliters

A customer is more likely to have 1 pet and no children than they are to have 2 pets and no children.

We are given a table with 3 columns titled "have children", "do not have children" and "total".

Under the row titled "1 pet", the respective probabilities are;

P(having 1 pet and children) = 38/91 =  0.4176

P(having 1 pet and no children) = 53/91 = 0.5824

Under the row titled "2 pets", the respective probabilities are;

P(having 2 pets and children) = 85/126 = 0.6746

P(having 2 pets and no children) = 41/126 = 0.3254

Under the row titled "3 or more pets", the respective probabilities are;

P(having 3 or more pets and children) = 46/118 = 0.3898

P(having 3 or more pets and no children) = 72/118 = 0.6102

Answer:

The mean means average. To find it, add together all of your values and divide by the number of addends. The median is the middle number of your data set when in order from least to greatest. The mode is the number that occurred the most often. The range is the difference between the highest and lowest values.

Answer:

hope this helps!!

Step-by-step explanation:

Mode: Are there two students who have the same number of children (could be zero)? If yes, that’s the mode. If not, there is no mode. Median: Put all five numbers in a row from lowest to greatest. The one in the middle is the median. Range: Take the difference of the greatest minus the lowest and that is the range.

Using the t-distribution, the most appropriate conclusion for the hypotesis test is given by Phone use did not change.

Suppose we're specified that:

The sample mean = [tex]\overline{x}[/tex]

The population mean =[tex]\mu[/tex]

The population standard deviation = [tex]\sigma[/tex]

The sample size = n

Then the z-statistic for this data is found as:

[tex]Z = \dfrac{\overline{x} - \mu}{\sigma/\sqrt{n}}[/tex]

In this problem, the values of those parameters are as follows:

The sample mean  [tex]\overline{x}[/tex] =  -0.2

The population mean =[tex]\mu[/tex] = 0

The population standard deviation = [tex]\sigma[/tex] = 9.1

The sample size = n = 200

Hence, the test statistic is given by:

[tex]Z = \dfrac{\overline{x} - \mu}{\sigma/\sqrt{n}}\\\\\\Z = \dfrac{-0.2- 0}{9.1/\sqrt{200}}\\\\z = 0.31[/tex]

Thus,

t = 0.31.

Since the absolute value of the test statistic is less than the critical value, we do not reject the null hypothesis and the conclusion is:

Area=16.65

Perimeter=26.3

Step-by-step explanation:

To find the area of a triangle, you must multply the length and height and divide by two. An equation like this could help find the area of a triangle: A=2÷(L×W) In your case, 7.4 is the length and 4.5 is the base. Multiply 7.4 and 4.5 together and divide the result by 2.

To find the perimeter, just add 7.4, 6.3, and 12.6 together. 4.5 doesn't get added, only the 3 sides of the triangle do. Don't forget to label the measurements.
