which two ratios form a proportion
A 1:2 and 4:2
b 1:2 6:3
c2:1 2:4
d 2:1 and 6 :3

Answers

Answer 1

Answer:c

Step-by-step explanation:

Did the test

Answer 2

Answer:

D. 2:1 & 6:3

Step-by-step explanation:

Proportion means equal so we need to see which ratios are equal.

To do that we need to make one fo the numbers in the ratio equal the corresponding number in the other ratio, then see if the other matches.

A:

1:2 & 4:2

The second number is already the same but the first isn't, therefore it is not proportional.

B:

1:2 & 6:3

To get 1 to equal 6 we must multiply it by 6, and what you do to one side you must do to the other so we have to multiply 2 by 6 as well

6:12 & 6:3

The first numbers are the same but the second isn't, therefore it is not proportional.

C:

2:1 & 2:4

The first numbers are the same but the second isn't, therefore it is not proportional

D:

2:1 & 6:3

to get 2 to equal 6 we need to multiply it by 3, which means we have to multiu 1 by 3 too

6:3 & 6:3

These are equal so this is proportional.

First, rewrite 17/25 and 13/20 so that they have a common denominator. Then, use to order 17/25 and 13/20

Answers

Answer:

The common denominator is 100 because they dont have a number lower so 20*5 is 100 and 25*4 gives you 100

Step-by-step explanation:

To find a common denominator for [tex]17/25[/tex] and [tex]13/20[/tex], we need to find the least common multiple (LCM) of 25 and 20.

The LCM of 25 and 20 is 100, so we need to rewrite the fractions with denominators of 100. Let's start with [tex]17/25[/tex]. To convert 25 to 100, we multiply both the numerator and denominator by 4. Thus[tex], 17/25[/tex] is equivalent to [tex]68/100[/tex].

Now let's convert 13/20 to a fraction with a denominator of 100. To convert 20 to 100, we multiply both the numerator and denominator by 5.This gives us [tex]65/100.[/tex] Now that both fractions have a common denominator of 100, we can easily compare them.

The fractions [tex]68/100[/tex]and [tex]65/100[/tex] can be ordered by comparing their numerators. Since 68 is greater than 65, we can conclude that [tex]17/25[/tex] is greater than [tex]13/20[/tex]. Therefore, following the conversions and calculations, we can order the fractions as [tex]17/25 > 13/20.[/tex]

C) Are the two contrasts defined in (a) and (b) mutually orthogonal? Explain why or why not. D) Conduct a F test about the linear contrast defined in (a). Use a = 0.05

Answers

Answer:

Following are the solution to the given point.

Step-by-step explanation:

In point a:

Linear comparison of the mean burning period of textiles of type three different from the mean type 4 burn time:  

[tex]\to C_1= \bar{y_3}- \bar{y_4}[/tex]

In point b:

Linear comparison to the moderate burning time of type 1 textiles distinct from the average burn periods of all the other three styles of textiles[2,3,4]:  is  

[tex]\to C_2 = \bar{y_1} - \frac{1}{3} \bar{Y_2} - \frac{1}{3} \bar{Y_3} - \frac{1}{3} \bar{Y_4}[/tex]

In point c:

The comparison in a and (b) above is orthogonal to one another. Since the number of coefficient products is :

In point d:

The contrast value is [tex]C_1 = \bar{y_3} -\bar{y_4}.[/tex] The estimate of the contrast:

[tex]=14.5-15.6\\\\=-1.1[/tex]

The standard error is

                   [tex]= \sqrt{0.795 \times \frac{2}{4}}\\\\ = \sqrt{0.3975}\\\\= \sqrt{0.6305}[/tex]

[tex]t= \frac{(\bar{y_3} - \bar{y_4})}{SE(\bar{y_3} - \bar{y_4})}= \frac{-1.1}{0.6305}= -1.7447[/tex]

T is 2.1788 as the critical value. Since the value of t=1.7447<th of the critical value is absolute, the null is not rejected  

The hypothetical one. theory. Therefore the impact of contrast is not statistically significant.  

As we know t is a test F. Alternatively, as we know. The F-statistics at 1,12 df is [tex]t^2 = -1.7445^2 = 3.0440.[/tex]

F test is critical to 4,7472.

43.95963871

Step-by-step explanation:

I used the tangent. Tangent is opposite over adjacent sides. To set it up, tan(7)=opp/16

move around to get opp=(16)tan(70)

opp=43.95963871

nearest whole height= 44 ft

Step-by-step explanation:

Step 1:  List out all of the formulas for the trigonometric functions

sin(x) = opposite/hypotenuse

cos(x) = adjacent/hypotenuse

tan(x) = opposite/adjacent

Step 2:  Find the equation for h

tan(70) = h / 16

16 * tan(70) = h

Step 3:  Solve for h

h = 16 * tan(70)

h = 43.9596

h = 44 ft

Answer: 44 ft
