Solve the following proportion for u. 7/u=3/11 Round to the nearest tenth.

For a proportional relationship between the volume of flour used (in cups), x, and the number of baked muffins, y, the constant of proportionality is 4.

Constant of proportionality, also known as constant ratio or constant rate, refers to is the ratio that relates two given values in a data set that is represented as a proportional relationship. When two parameters are proportional, either directly or indirectly, the relationship is expressed as a = kb or a = k/b, where k indicates the relationship between the two variables and is known as the proportionality constant. In the given data, the proportionality constant is:

k =b/a = 8/2 =12/3 = 16/4 = 20/4 = 4

Hence, the proportionality constant for the given data is 4.

Step-by-step explanation:

The line is in a positive trend we can see it because when we read it from left to write we can see it go up. The point where we start is 5 levels down from the second point  3 units to the left.

We can model this using  rise/run

Rise = 5

The solutions are,

The radians wade sweep out is 2.875 radians.

When wade stops skiing, he is 0.799km to the right of the center of the ski trail.

When wade stops skiing, he is 0.003km above the center of the ski trail.

Given that;

Wade is traveling along a 0.8 km-radius circular ski trail. Wade moves 2.3 kilometers counterclockwise starting at the three o'clock position.

Radius (r) = 0.8km

Distance (s) = 2.3km

Here, we need to find three cases, they are;

Case(I): how many radians does wade sweep out;

The relation between radians and radius is given by,

s = rθ

2.3 = 0.8*θ

θ = 2.3/0.8

θ = 2.875

The radians wade sweep out is 2.875 radians.

Case (II): when wade stops skiing, how many km is wade to the right of the center of the ski trail;

Let, Ф = π - 2.875

      Ф = 0.266 radians

Then, x = r*cosФ

          x = 0.8*cos(0.266)

          x = 0.799

When wade stops skiing, he is 0.799km to the right of the center of the ski trail.

Case (III): when wade stops skiing, how many km is wade above the center of the ski trail;

Let, y = r*sinФ

      y = 0.8*sin(0.266)

      y = 0.003

When wade stops skiing, he is 0.003km above the center of the ski trail.

Therefore, the required solutions are;

The radians wade sweep out is 2.875 radians.

When wade stops skiing, he is 0.799km to the right of the center of the ski trail.

When wade stops skiing, he is 0.003km above the center of the ski trail.

The values of p and ρˆ (p-hat) in the sample are

p = 0.65 and ρˆ (p-hat) = 0.4

From the question, we have the following parameters that can be used in our computation:

Proportion of female goats = 65%

Sample = 5

Female = 3

The proportion of female represents the variable p

So, we have

p = Proportion of female = 65%

This gives

p = 65%

Express as decimal

p = 0.65

The variable ρˆ (p-hat) is then calculated as

ρˆ = x/n

In this case,

x = Female = 2

n = Male + Female = 2 + 3 = 5

So, we have

ρˆ = 2/5

Evaluate

ρˆ = 0.4

Hence, the values are 0.48 and 0.44, respectively

Option B is correct.

Given that   Function G(F(x)) = (x - 5)3 + x - 5 ;

Lets take a function G(x) = x3 + x as (i) and check that it will produce the above equation or not.

Now suppose that the value of the function F(x) = x-5 as (ii) , using this value we will check that whether it support the value for g(x) or not.

Put the value of  function  f(x) in the equation number i , it will be like this :

G(f(x)) = f(x)3 + f(x)

we know that the value of f(x) from (ii)

The cost of 3 bottles of juice based on the given ratio will be $2.61.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

18 bottles cost = $15.66

1 bottle cost = $15.66/18 = $0.87/ bottle

For 3 bottles = 3 × $0.87 = $2.61

The value of x in the given isosceles triangle is x = 15

From the question, we are to determine the value of x.

From the given information,

The length of the base of the isosceles triangle is x

Also,

The length of a leg is 4x - 3

Since, the length of the legs of an isosceles triangle are equal,

Then,

The length of the other leg is 4x - 3

Also, form the given information,

The perimeter of the triangle is 129

Thus,

x + 4x - 3 + 4x - 3 = 129

Now, solve for x

x + 4x - 3 + 4x - 3 = 129

Collect like terms

x + 4x + 4x = 129 + 3 + 3

9x = 135

Divide both sides by 9

9x/9 = 135/9

x = 15

Hence, the value of x is 15

The incidence rate of disease x among persons exposed to factor a is 0.04

The frequency of a particular incident over a predetermined time period is measured by the incidence rate or incidence. In the corporate world, sampling, surveys, and product testing can all be used to calculate an incidence rate.

Because 120 divided by the total number of exposed people yields the occurrence rate for disease X among those who have been exposed.

The incidence rate would be 4 per 100 people if multiplied by 100, however, this statistic is not specifically specified.

Therefore, those who were exposed to factor a had an incidence risk of disease x of 0.04

Equation of the line for the given graph in slope-intercept form is given by  y = 5x -1.

As given in the question,

From the given graph,

Consider pair of two coordinates we have,

(x₁ , y₁) = (1, 4)

(x₂ , y₂) = (0,-1)

Equation of the line for the given graph in slope-intercept form is given by:

(y -y₁) / (x -x₁)= (y₂ -y₁) / (x₂ -x₁)

⇒ ( y - 4)/ (x -1) = (-1-4)/(0-1)

⇒(y-4)/(x-1) = 5

⇒y-4 = 5(x-1)

⇒y = 5x -5 +4

⇒ y= 5x -1

Therefore, equation of the line for the given graph in slope-intercept form is given by  y = 5x -1.

Answer:

Option B is perpendicular to y=-3x+4 and goes through point (-1,5)

Step-by-step explanation:

We will look for an equation of the form y=mx+b, where m is the slope and b the y-intercept.  The reference line, y=-3x+4, has a slope of -3.  A line perpendicular to this line will have a slope that is the "negative inverse" of the refence lines slope.  In this case, it's slope would be +(1/3).

We could graph each of the equation options and look for one that is perpendicular, but it might be faster to simply rearrnaged the options into standard format of y=mx+b. which we'll do here:

Option   Rearranged Equation   Slope

A) 3y=-x+16

                  y = -(1/3)x+(16/3)           -(1/3)

B) 3y=x+16

                   y = (1/3)x + (16/3)         (1/3)

C) y=-3x+8                                           -3

D) y=-3x+2                                            -3

There is only one option that has the required slope to be parallel to the reference equation (y=-3x+4), option B:  y = (1/3)x + (16/3)

Does it go through point (-1,5)?

y = (1/3)x + (16/3)

Enter x = -1 and find 5:

y = (1/3)(-1) + (16/3)

y = (16/3)-(1/3)

y = (15/3) or 5

 Yes, it goes through point (-1,5)

Option B is perpendicular to y=-3x+4 and goes through point (-1,5).

Jeanne can make 3 pairs of shorts with 3 7/8 yards of fabric.

What do you mean by ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

The total amount of fabric = 3 7/8 yards = 31/8 yards.

Amount of fabric needed to make 1 pair of shorts = 1 1/4 = 5/4 yards.

The number of shorts that can be made = 31/8 ÷ 5/4

⇒ 3.1 so it will be 3 because no relevance of decimal shorts.

Hence "Jeanne can make 3 pairs of shorts with 3 7/8 yards of fabric".
