Answer: 0.4

Have a nice day!

Answer:

0.4 or 2/5

Step-by-step explanation:

You can solve this question by doing [tex]\frac{1}{5}[/tex] x [tex]\frac{2}{1}[/tex] to get the answer of [tex]\frac{2}{5}[/tex] or 0.4.

Answer:-3c +24

Step-by-step explanation:

-3(c) and -3 (-8)

-3c and two negatives equal a positive, so +24

Answer:

[tex]\cos\ A = \frac{2}{4.5}[/tex]

Step-by-step explanation:

Given

[tex]sin\ A = \frac{2}{4.5}[/tex]

See attachment

Required

Explain and correct the error

The error in the equation is that: the formula of cosine of angle A is used to calculate the sine of angle A.

The ratio can be corrected as by using:

[tex]\cos\ A = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos\ A = \frac{AC}{AB}[/tex]

[tex]\cos\ A = \frac{2}{4.5}[/tex]

Answer:

6:7

Step-by-step explanation:

divide both sides by 7...

Answer:

I can's make out the line, but, you can plot two points, (try to make them whole numbers ie (3,6), (4,8)), subtract the point with the smallest x value from the other point ((4,8)-(3,6)=(1,2)) Divide the new y, by the new x (2/1), and you have your slope.

Answer:

y=3x/2-3

Step-by-step explanation:

y=mx+c

9=m(8)-3

9+3=8m

12=8m

m=12/8

m=3/2

The equation of the line is y=3x/2-3

Answer:

1.50 + 13.75 = 15.25

15.25 x 579.50 = 38

ok so basically you take the total and divide it by the total of one student!! :)

answer is: 38

Answer:

Step-by-step explanation:

The side given is opposite the given angle. We want to find both the hypotenuse and the adjacent side in the right triangle that models the geometry.

  Sin = Opposite/Hypotenuse

  sin(50°) = (230 ft)/h

  h = (230 ft)/sin(50°) ≈ 300.24 ft

The length of the cable must be about 300.2 feet.

__

  Tan = Opposite/Adjacent

  tan(50°) = (230 ft)/d

  d = (230 ft)/tan(50°) ≈ 192.99 ft

The cable must be anchored about 193.0 ft from the tower.

Answer:

Step-by-step explanation:

x = width

6x - 8 = length

2x + 6x - 8 = 40

8x = 48

width = 6 feet

length = 28 feet

Pair 1 and pair 3 have congruent polygons.

A polygon is said to be congruent if it has the same shape, sides that are the same length, and internal angles as the polygon it is being compared to. The criterion is satisfied if all of the congruent shapes are of the same type.

Pair 1: The polygons are identical in size and shape.

Pair 2: The polygons are identical in shape but vary in size.

Three: The polygons are the same size and shape.

Pair 4: The polygons are identical in shape but vary in size.

Here, pair 1 and pair 3 have congruent polygons.

Answer:

hello some part of your question is missing below is the missing part

If Dayton's machine is being used on a trial basis, should its purchase be considered?  C.V.(S) =  Test Statistic=   P-Value=   Decision: Conclusion:

answer :

i ) Cv(s) = 51.739

ii)  T = 44.8

iii)  p-value  = 0.0082

iv)   we do not fail to reject H0 ( since p-value < 0.05 )

v ) The new machine fills the bottles with a lesser variation

Step-by-step explanation:

we will test the hypothesis in regards to the standard deviation of the population

The hypothesis are    

H0 : б = 0.15

Ha : б < 0.15

hence at ∝ = 0.05    where n = 71

i) critical point for left sided test = [tex]x^2_{1-\alpha } , n - 1[/tex]

hence Cv(s) = 51.739

ii) Test statistic = T = ( n - 1 ) s^2 / б^2

 s = 0.12 , n = 71 , б = 0.15

hence T = 44.8

iii) P-value =  p ( [tex]x^{2} _{70}[/tex] < 44.8 )  = 0.0082

iv ) Decision : we do not fail to reject H0 ( since p-value < 0.05 )

v ) conclusion : The new machine fills the bottles with a lesser variation

Answer:

C

Step-by-step explanation:

slope is the change of y / change of x

.

we can pick any points and find the changes in y and x

lets pick (0 , 0) and (5 , 6) .

the change of y = 6-0 = 6.

the change of x = 5-0 = 5.

so the slope of the line is 6/5

.

Answer:

x = 10.2

Step-by-step explanation:

Formula:

a² + b² = c²

16² + b² = 19²

256 + b² = 361

b² = 361 - 256

b² = 105

b = 10.2
