Answer:

the p-value for this test of hypothesis is 0.0324

Step-by-step explanation:

Given the data in the question;

sample size n = 38

Null hypothesis             H₀ : μ = 20

Alternative hypothesis Hₐ : μ ≠ 20

z = 2.14

Test Statistic;

since its a two tailed test, p-value will be;

⇒ 2 × P( Z > |z| )

= 2 × ( 1 - P( Z < |z| ) )

we substitute in the value of z

= 2 × ( 1 - P( Z < 2.14  ) )

from z score table, P( Z < 2.14 ) = 0.9838

= 2 × ( 1 - 0.9838 )

= 2 × ( 0.0162 )

P-value = 0.0324

Therefore, the p-value for this test of hypothesis is 0.0324

Answer:

HI, IG, GH

Step-by-step explanation:

First, you need to find the missing angle; do this by subtracting 48 and 89 from 180. This means the missing angle is 43. The smallest side will be across from the smallest angle. So in order of least to greatest, the sides are HI, IG, GH.

Answer:

the function that models the total inventory costs as a function of x is;

$( [tex]\frac{112500}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

Step-by-step explanation:

Given the data in the question;

cost of storing the shoes ( Holding cost ) = $ 3 per year

ordering cost ( Co ) fixed = $ 25 per order

cost of each pair = $ 5 per shoe pair

Total demand = 4500 shoe pairs

Total Inventory cost = Holding cost Ordering cost

so

Total Inventory cost = [tex]\frac{4500}{x}[/tex]( $ 25) + [tex]\frac{1}{2}[/tex]× $3 × x

Total Inventory cost = $( [tex]\frac{4500*25}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

Total Inventory cost = $( [tex]\frac{112500}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

Therefore, the function that models the total inventory costs as a function of x is; $( [tex]\frac{112500}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

Answer:

B. The equation represents a function, but not a linear function.

Step-by-step explanation:

Equation with x squared:

A equation in which the highest power of x is 2, that is, a term [tex]ax^2[/tex], is called a quadratic function.

In this question:

[tex]y = 4x^2[/tex] is a function.

However, since the highest power of x is 2, it is not a linear function, it is a quadratic function, and the correct answer is given by option B.

Answer:

Start: x = 141°

141° and x are alternate interior angles and congruent because the lines are parallel

Go left: x = 39°

39° and x are corresponding angles, and therefore congruent

Go down: x = 139°

180 - 41 = 139, the angle next to 41 and x are corresponding angles

Go left: x = 98°

180 - 82 = 98, the angle next to 82 and x are corresponding angles

Go down: x = 102°

102° and x are vertical angles and therefore congruent

Go right: x = 50°

180 - 130 = 50, the angle next to 130 and x are corresponding angles

Go down: x = 74°

corresponding angles

Go right: x = 83°

corresponding angles

Go right: x = 95°

corresponding angles

Go up: x = 18°

corresponding angles

Go left: x = 166°

180 - 14 = 166, consecutive interior angles are supplementary (I'm confused? none of the answers have it but they're definitely consecutive interior...)

Answer:

x = 21 degrees

Angle KMH = 96 degrees

Step-by-step explanation:

The first question is what is x. To find that out the opposite angle of 4x is the same as x. That is 84 degrees. So take 84 and divide it by 4 you get 21.

x = 21 degrees.

The second question is what is the angel of KMH. A straight line is 180 degrees. If you take the 84 degrees and subtract it from 180 you will get what that angle equals. It equals 96 degrees.

Answer:

opposite = 5√2

adjacent 5√2

Step-by-step explanation:

the opposite leg can be determined using

Sin = opposite / hypotenuse

√2 / 2= opposite / 10

opposite = 5√2

the adjacent leg can be determined using

cos = adjacent / hypotenuse

√2 / 2= adjacent / 10

adjacent = 5√2

Answer:

Each class should get 17 tickets. 4 tickets will be left over.

Step-by-step explanation:

157/9=17.444... -> 17 per class

17 x 9 = 153

157-153= 4 left

Each class should get 17 tickets and 4 tickets will be left.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total tickets= 157

and, Total classroom among which the tickets to be divided= 9.

So, each classroom have

= 157/ 9

= 17 with 4 left

Hence, 17 tickets are divided equally and 4 tickets are left.

this is because one quart is 4 cups and 4 quarts are one gallon. this means that if you use three quarts, you have one left over. one quart is the same as 4 cups

that "photo" is a danger to your device

One quart is the same as the 4 cups of milk she has leftover, the option C is the correct answer.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Sondra has 1 gallon of milk. Her pudding recipe calls for 1 quart of milk, but she triples the recipe.

1 gallon of milk = 1 quart of milk,

one quart is 4 cups and 4 quarts is one gallon which means that if you use three quarts, you have one leftover.

Answer:

[tex]A=227.84\ inch^2[/tex]

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 5 inch

Hight, h = 12 m

Radius, r = d/2 = 2.5 m

We need to find the surface area of the cylinder. The formula for the surface area of the cylinder is given by :

[tex]A=2\pi rh+2\pi r^2\\\\A=2\times \dfrac{22}{7} \times 2.5\times 12+2\pi \times 2.5^2\\\\A=227.84\ inch^2[/tex]

So, the lateral surface area of the cylinder is equal to [tex]227.84\ inch^2[/tex].

Answer:

Step-by-step explanation:

diameter= 22 mm

Radius is half of diameter

r = 22/2 = 11mm

Area of circle = πr²

                      = 3.14 * 11*11

                      = 379.94 mm²

Diameter (d) of circle = 22 mm

Area of circle.

Diameter (d) of circle = 22 mm (Given)

So, radius (r) of circle = [tex] \frac{d}{2} [/tex] = [tex] \frac{22}{2} [/tex] = 11 mm.

Now, we know,

Formula of Area of Circle is πr².

So, Area of Circle = [tex] \frac{22}{7} [/tex] × (11)²

Area of Circle = [tex] \frac{22}{7} [/tex] × 11 × 11

Area of Circle = [tex] \frac{22 \: × \: 11 \: × \: 11}{7} [/tex]

Area of Circle = [tex] \frac{2662}{7} [/tex]

Area of Circle = 380.29
