Answer:

It is 51

Step-by-step explanation:

because you have to add the 80 and 49 them you will get 129 and then subtract 180 by 129 then you will get your answer

Answer:

51°

Step-by-step explanation:

Sum of angles in a triangle is supplementary,

x + 49° + 80° = 180°

x + 129° = 180°

x = ( 180 - 129 )

x = 51°

D Not similar

Step-by-step explanation:

For similar triangles the sides are always in proportions.

Here two sides are in proportion but third side isn't. So triangles are not similar.

Step-by-step explanation:

False. the number is the x coordinate

True. the x-axis is horizontal

False. 0,0 is called the origin.

Answer:

43.65 cm squared

Step-by-step explanation:

Answer:

16 square inches

Step-by-step explanation:

Given

Triangle (4)

[tex]Height = 3[/tex]

[tex]Base = 2[/tex]

Square (1)

[tex]Length = 2[/tex]

Required

The surface area of the star

This is calculated as the area of the square added to the area of the 4 triangles.

The area of the square is:

[tex]Area =Length^2[/tex]

[tex]A_1= 2^2[/tex]

[tex]A_1= 4[/tex]

[tex]The\ area\ of\ 1[/tex] of the triangles is:

[tex]Area = 0.5 * Base * Height[/tex]

[tex]A_2 = 0.5* 3 * 2[/tex]

[tex]A_2 = 3[/tex]

For the 4 triangle, the area is 4 * A2

So, the total area is:

[tex]Total = A_1 + 4 * A_2[/tex]

[tex]Total = 4 + 4 * 3[/tex]

[tex]Total = 4 +12[/tex]

[tex]Total = 16[/tex]

Answer:

We accept H₀. The information is not enough to reject H₀

Step-by-step explanation:

In 2011

Mean for the cost of a private room in a nursing home    μ = 239  $/day

Sample in 2021

265  283 266 366 243  334  213  266 140 276 292

average  =  x  = 267,64

Standard deviation  s  = 56,31

We assume a normal distribution. Random sample,  sample size and the fact that population standard deviation is unknown drive to develop a           t -student two-tail test at 5 % of significance level

n = 11    then degree of freedom   df  =  n  -  1    df  = 10

Then from t-student table df = 10 and α = 0,05   α/2 = 0,025

we get t(c) =  2,228

Hypothesis Test:

Null Hypothesis                       H₀         x  =  μ  = 239

Alternative Hypothesis           Hₐ         x  ≠  μ

To calculate  t(s)

t(s)  =  (  x  -  μ ) / s/ √n

t(s)  =  ( 267,64  - 239 ) / 56,31/√10

t(s) =  28,64 *3,16 / 56,31

t(s) = 1,61

Comparing   t(s)  and t(c)

t(s) < t(c)

Then t(s) is in the acceptance region we accept H₀ . We did´t found enough evidence to reject H₀

Answer:

[tex]y = 7.5[/tex]

Step-by-step explanation:

Given

Direct variation implies that:

[tex]y = kx[/tex]

Where k is the constant of variation.

[tex]x=4; y=3[/tex]

Required

Find y when [tex]x = 10[/tex]

[tex]y = kx[/tex]

Make k the subject

[tex]k = \frac{y}{x}[/tex]

For: [tex]x=4; y=3[/tex]

[tex]k = \frac{3}{4}[/tex]

For: [tex]x = 10[/tex]

[tex]k = \frac{y}{x}[/tex] becomes

[tex]k = \frac{y}{10}[/tex]

Substitute [tex]k = \frac{3}{4}[/tex]

[tex]\frac{3}{4} = \frac{y}{10}[/tex]

Make y the subject

[tex]y = \frac{3}{4} * 10[/tex]

[tex]y = \frac{3* 10}{4}[/tex]

[tex]y = \frac{30}{4}[/tex]

[tex]y = 7.5[/tex]

Answer:

7.1 in

Step-by-step explanation:

Given:

θ = 45°

Radius (r) = 9 in.

Required:

Length of the arc

Solution:

Arc length = θ/360 × 2πr

Plug in the values

Arc length = 45/360 × 2 × π × 9

Arc length = 7.06858347 = 7.1 in (nearest tenth)

Answer:

1) 0.84 ( a )

2) The sample proportion is not less than 0.65 ( D )

Step-by-step explanation:

1) The value of a is the value of the alternate hypothesis

since he wrongly Identifies a student as a Business major  16% of the time

The value of the alternate hypothesis ( Ha : = 1 - 0.16 = 0.84

                                              while  H0 : = 0.87

2) An appropriate alternative hypothesis

 Ha : μ ≥ 0.65  ( The sample proportion is not less than 0.65 )

The value of a is the value of the alternate hypothesis is 0.84 .

The sample proportion is not less than 0.65.

       The student correctly identify that person as a business major 87% of              

       the time.

       Since he wrongly Identifies a student as a Business major 16% of the      

        time.

      The value of the alternate hypothesis ( Ha : = 1 - 0.16 = 0.84 )

     while  H0 : = 0.87

        The value of a is 0.84.

Statistical hypothesis testing, the alternative hypothesis is a position     that states something is happening, a new theory is preferred instead of an old one. It is usually consistent with the research hypothesis because it is constructed from literature review, previous studies, etc.

       An appropriate alternative hypothesis

       Ha :  μ ≥ 0.65 .

      The sample proportion is not less than 0.65 .

Answer: 26

Step-by-step explanation:

Angles on a straight line add to 180 degrees, so:

[tex]4x+4+4x-32=180\\\\8x-28=180\\\\8x=208\\\\x=26[/tex]

The value of x is 26.

A straight line is an endless one-dimensional figure that has no width

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint.

The angles add up to 180 degrees in a straight line.

The two angles are 4x+4 and 4x-32

4x+4+4x-32=180

Add the like terms

8x-28=180

Add 28 on both sides

8x=180+28

8x=208

Divide both sides by 8

x=26

Hence, the value of x is 26.
