Based on the student's work, the equation was solved incorrectly. B. The equation solved correctly would show that it has one solution(s).

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For instance, 2x - 5 = 13. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign.

In correct solution of the equation is given as:

4(2 - 3x) = x - 2(2x + 1)

8 - 12x = x - 4x - 2

8 - 12x = -3x - 2

8 + 2 = 12x - 3x

10 = 9x

Answer:

x = 5

Step-by-step explanation:

5(2x-11) = -5

5(2x-11) = -510x - 55 = -5

5(2x-11) = -510x - 55 = -510x - 55 + 55 = -5 + 55

5(2x-11) = -510x - 55 = -510x - 55 + 55 = -5 + 5510x = 50

5(2x-11) = -510x - 55 = -510x - 55 + 55 = -5 + 5510x = 5010x / 10 = 50 / 10

Answer:

1.339 Canisters

Step-by-step explanation:

Because you are making 5 meatloafs for a party, and according to the recipe you need 1 1/4 cup of breadcrumbs per each meatloaf. In each canister there is 14/3 cups of breadcrumbs which you can see by multiplying the serving size by the servings per container.

Since you need five meatloafs, you can figure out how many cups of breadcrumbs you need by multiplying 1 1/4 cups by 5. This gives you 6 1/4 or 6.25 cups.

In each canister of breadcrumbs, there are 14/3 cups or 4.667 cups of breadcrumbs.

To figure out how many canisters you need, you divide the amount of breadcrumbs you need (6.25 cups) by the amount of breadcrumbs you have (4.667) which gives you 1.339 canisters.

What is Distance?

a velocity is a unit of measurement for the Distance an object travels in a predetermined period of time. Here is a word equation that illustrates the connection between space, speed, and time: velocity is calculated by dividing the total Distance traveled by the journey time.

Diane and Douglas both drive at an average rate of 50 miles per hour. So if they travel for the same time they will end up covering the same Distance as well.

As we know velocity = rate of change of displacement

The distance the bungee jumper falls is estimated as follows when the time of motion is 6 seconds;

6 = [tex]\frac{\sqrt{d} }{16}[/tex]

√d = 16*6

√d = 96

d = 9216

Hence the height of fall of the bungee jumper is 9216feet.

The highest score with an "F" grade is the 10th percentile score. To find the 10th percentile score, count 10% of the total number of scores, which is 100. So, the 10th percentile score is the 10th score from the bottom, which is 43.

A percentile score is a value on a scale that indicates the percentage of a set of observations that are below it. For example, a score of 80% on a test means that 80% of the test-takers scored below that score and 20% scored above it. In other words, the score separates the bottom 80% from the top 20%.

Any variable where the data indicate amounts is referred to be a quantitative variable (e.g. height, weight, or age). Any variable where the data represent groupings is referred to as a categorical variable.

The area of hubcap in shape of circle is 121π cm^2.

What is a circle?

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

The equation of circle in the plane is given as:

(x-h)^2 + (y-k)^2 = r^2

where (x, y) are the coordinate points

(h, k) is the coordinate of the center of a circle

and r is the radius of a circle.

and Area of circle = πr²

Circumference of circle=2πr

Now,

As shape of hubcap is circular.

Area of circle = πr^2

where r=D/2  D=diameter

Given diameter of hubcap is 22cm. --> r=11 cm.

Therefore,

                Area=π*11^2=121π cm^2

Hence,

          The area of hubcap in shape of circle is 121π cm^2.

The correct answer is B. While the measures of variation can be found they do not make sense because the data are nominal, they don't measure or count anything.

Any difference between the individuals in a species or between groups of organisms from any species is referred to as variation. Genetic variety is mostly caused through mutation, although other processes like sexual reproduction and gene flow also play a role.

Environmental variation refers to environmental elements that can contribute to variances. Inherited variation refers to the variance that is genetically transmitted during reproduction from parents to children.

The variable of interest is a nominal variable, which means it merely belongs to categories and doesn't actually have any "numerical" values. Only the categories' names—1, 2, 3, and 4—have been utilized.

Only "sample proportions" can be determined for nominal variables, and the variance between sample proportions of various samples may be calculated and compared, but measurements of variation within a single sample (as is the case here) are useless for nominal variables.

Therefore, Option B is the correct answer.

The average velocity for the time period beginning when t=3 and lasting for

1) 0.01 s: -9051.12 ft/sec

2) 0.005 s: -18051.06 ft/sec

3) 0.002 s: -45051.1 ft/sec

4) 0.001 s: -90051  ft/sec

Here, a ball is thrown with initial velocity of 46 ft/s.

The height of the ball in feet after t seconds is given by an equation,

 y = 21t - 12t²

Let us assume that P represents the average velocity.

The average velocity is given by formula,

P = [y(t₂) - y(t₁)]/[t₂ - t₁]

i) the average velocity for the time period beginning when t=3 and lasting  0.01 s

Here, t₂ = 3.01 s and  t₁ = 3 s

y(t₂) =  21(3.01) - 12(3.01)²

      = -45.5112

y(t₁) =  21(3) - 12(3)²

      = 45

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.5112

So, P = -90.5112 / (0.01)

     P = -9051.12 ft/sec

ii) the average velocity for the time period beginning when t=3 and lasting  0.005 s

Here, t₂ = 3.005 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.2553

So, P = -90.2553 / (0.005)

     P = -18051.06 ft/sec

iii) the average velocity for the time period beginning when t=3 and lasting  0.002 s

Here, t₂ = 3.002 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.1021 - 45

                = -90.1021

So, P = -90.1021 / (0.002)

     P = -45051.1 ft/sec

iv) the average velocity for the time period beginning when t=3 and lasting  0.001 s

Here, t₂ = 3.001 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.051 - 45

                = -90.051

So, P = -90.051 / (0.001)

The ordered pair that describes the location of R′′ is (-4,-2)

Explanation:

When a point is reflected over the x-axis, the x-coordinate remains the same and the y-coordinate changes sign. So, the point R' will be (4,-2)

When a point is reflected over the y-axis, the x-coordinate changes sign and the y-coordinate remains the same. So, the point R′′ will be (-4,-2)
