Step-by-step explanation:

the same scale factor has to apply to all sides.

we see for the left vertical side that for C it is 3 units long, for D it is 2 units long.

so, the scale factor is

3/2 = 1.5

to go from D to C we have to multiply all lengths by 1.5.

The values from the least to greatest is 160%, 1.8, 2.1, 220%, 16/5 .

In the question ,

it is given that

the values 9/4 , 160%, 1.8, 16/5 , 220%, and 2.1

to arrange the values , we first need to simplify all the values .

(i) the value 9/4 = 2.25

(ii) 160% = 160/100 = 1.60

(iii)the value 1.80

(iv) Simplifying 16/5 , we get 3.20

(v) Simplifying 220% = 220/100 = 2.20

(vi) the value 2.10

the least value is 1.60 which is 160%.

the greatest value is 3.20 which is 16/5 .

Therefore ,the values from the least to greatest is 160%,1.8,2.1,220%,16/5  .

The equation that can be used to represent the proportional relationship between time and the distance a greyhound dog can travel is:

y = 44x.

A direct proportional relationship is a function in which the output variable is found with the multiplication of the input variable and the constant of proportionality, as follows:

y = kx.

In which k is the constant of proportionality, also representing the rate between the output and the input for any pair of (input, output) except (0,0).

From the table of distances and time given in this problem, the constant is found as follows:

k = 220/5 = 440/10 = 660/15 = 44.

Hence the constant is of 44 and the relation is given by:

y = 44x.

If the actual mean is 18 ounces, there is a 0.0003 chance that the sample mean was 18.2 ounces or more.

Given that 18 ounces are what Kellogg estimates to be the typical weight of a box of Frosted Flaked. The average weight of the 30 cartons they sampled was 18.2 ounces. According to past data, the filling procedure's standard deviation is 0.32 ounces.

Let Y be a box weights random variable.

μ = 18 ounces

SD = 0.32 ounces

The sample size and mean are provided as,

Sample size (n)  = 30

Sample mean (y) = 18.2

Y then follows roughly the standard deviation N(μ = 18, SD = 0.32)

Z score appears as:

[tex]z = \frac{\sqrt{n}(y-u)} {SD}[/tex]

where z is a normal standard variable having a mean of 0 and a standard deviation of 1.

Since sample size n is 30 and the standard deviation is given. y follows approximately Normal distribution

If the actual mean is 18 ounces, the likelihood that the sample mean will have been 18.2 ounces or more is given as,

[tex]P[Y \geq 18.2] = P [\frac{\sqrt{n(y - u)} }{SD} \geq \frac{\sqrt{30}(18.2- 18) }{0.32}\\ \\ =P [z\geq \frac{\sqrt{30}* 0.2 }{0.32}]\\ \\= P [z\geq \frac{1.0954}{0.32}]\\ \\=P [z\geq 3.4233]\\\\= 0.0003[/tex]

Therefore, if the actual mean is 18 ounces, there is a 0.0003 chance that the sample mean was 18.2 ounces or more.

Answer: Degree of Polynomial: 12

Step-by-step explanation:

Roxanne claims that all linear equations represent proportional relationships. So, this statement "Yes, because all linear equations have graphs that are straight lines." makes him correct.

When there is a proportionate relationship between two variables, the other variable changes at a consistent pace regardless of how the first variable changes, grows or shrinks. A constant ratio between the two variables can be thought of as the constant rate.

Equations, graphs, and tables that use proportions can be used to show proportional relationships. A broad structure is followed by the proportional relationship equation, which will be taught in this session. Straight lines are used to illustrate the graphs. The tables are sets of numbers that are always paired in the same ratio.

Hence the correct option is A

A parabola is an approximately U-shaped, mirror-symmetrical planar curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

Given Data

Standard form of quadratic equation

Y = ax² +bx + c

Given points

(3,9), (30,-9). (0,1)

Equating points in formula

9= a(3)² + b(3) + c

9 = 9a + 3b +c

-9 = a(30)² + 3(30) + c

-9 = 900a + 90 + c

1 = a(0)² + b(0) + c

c = 1

Equating c in the equation

9 = 9a + 3b +1

8 = 9a + 3b

-9 = 900a + 90b +1

-10 =  900a + 90b

Multiplying both sides by 100

800 = 900a + 300b

-10    = 900a + 90b

--------------------------

790 = 210b

b = 4 (rounding off)

Putting values of b into equation

8 = 9a + 3(4)

20 = 9a

a = 2 (rounding off)

Equation is y = 2x² + 4x + 1.

Average speed measures how fast an object or a person is travelling with respect to time. Average speed is the ratio of total distance travelled and total time travelled.

Average speed = total distance / total time

Total distance = 4.5 + 2/3 + 9

= 4.5 + 9 + 0.67 = 14.2 miles

Total time = 30 + 20 + 45 = 95 minutes = 1 hour 35 minutes  = 1 7/12 hours = 1.6 hours

1b. 15 cups of dry rice will serve 45 people.

2. 30 spring rolls = 15 people

40 spring rolls = 20 people

56 spring rolls = 28 people

Step-by-step explanation:

1a. To find a constant, the equation is y/x. When 6 is divided by 2, you get 3 and from there the input increases by 3.  So, you multiply 10 by 3 to find how many people it can serve.

1b. To find this answer, you divide 45 by 3 to get 15. So 15 cups will serve 45 people.

2. Any number in the second column is divided by .5 to get the number in the first column. Any number in the first column is multiplied by .5 to get the number in the second column.
