Brad looks at a scatterplot that shows the correlation between the typical population's access to health insurance and the number of cars owned by each household in different parts of the country. A substantial positive association can be seen in the plot.

What are some examples of scatter plots?

The association between two sets of data is depicted by points on a scatter (XY) plot. Each dot in this illustration represents the weight and height of one individual. (The information is displayed as "Cartesian (x,y) Coordinates")

What is the purpose of a scatter plot?

Data points are plotted on a horizontal and vertical axis using scatter plots in an effort to demonstrate the degree to which one variable is influenced by another.

                 The values of the columns selected on the X and Y axes determine where each row in the data table is represented by a marker, whose position.

Step-by-step explanation:

The side lengths do not satisfy the triangle inequality.

The coordinates of the endpoints of the segment T'V' are equal to: A. T'(-3, 6) and V'(0, 3).

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Next, we would have to dilate the coordinates of triangle TVW by using the following transformation rule with a scale factor of 3/4: (x, y)  →  (3x/4, 3y/4)

For coordinate T, we have;

Coordinate T = (-4, 8)  →  (3/4(-4), 3/4(8)) = Coordinate T' = (-3, 6).

For coordinate V, we have;

Coordinate V = (0, 4)  →  (3/4(0), 3/4(4)) = Coordinate V' = (0, 3).

By applying formulas of logistic growth we can find the answers as part (a) P(t) = 1800 / (1+3e^(-0.8t)) and part(b) 1.37 years

In a logistic growth the growth rate decreases with the passage of time until the growth reaches the maximum capacity at infinite time.

The formula is f(t) = L / (1+ ye^(-kt))

where L is the maximum value, k is the growth rate, y is a constant and t is time.

Part(a)

In this case, L = 1800, k = 0.8 yr-1

f(t) = 1800 / (1 + ye^(-0.8)t)

at t = 0 , f = 450,

450 = 1800/ (1+y)

solving this gives, y = 3

Thus the final answer is f(t) = 1800/ (1+ 3e^(-0.8t))

Part(b)

we need to find the time when f(t) = 900

900 = 1800/(1+3e^(-0.8t))

t = 1.37 years

Answer:

(a) They paid $25-$15=$<<25-15=10>>10 to make each wreath.

(b) They collected $15114=$<<15114=1710>>1710.

(c) They made $1710-$10114=$<<1710-10114=180>>180.

(d) They sold $180/$15=<<180/15=12>>12 wreaths.

Step-by-step explanation:

Sure, here is a breakdown of the solution:

(a) The cross-country team paid $10 to make each wreath because they sold the wreaths for $25 and made $15 for each wreath they sold, so the cost to make each wreath was $25-$15=$10.

(b) They collected $1710 because they sold 114 wreaths and made $15 for each wreath they sold, so they collected a total of $15*114=$1710.

(c) They made $180 because they collected $1710 and it cost them $10 to make each wreath, and they sold 114 wreaths, so the total cost of making all the wreaths was $10*114=$1140. They made $180 because they collected $1710 and it cost them $1140 to make all the wreaths, so their profit was $1710-$1140=$180.

(d) They sold 12 wreaths because they made $180 and it cost them $15 to make each wreath, so they sold $180/$15=12 wreaths.

Examples of a continuous function that is continuous at exactly one point are x=0,1,2,3,4.

In mathematics, a continuous function is one where a continuous variation of the argument results in a continuous variation of the function's value (i.e., a change without a leap). This indicates that there aren't any discontinuities or sudden changes in value. More specifically, a function is continuous if it is possible to guarantee that its value will not vary significantly even with arbitrarily tiny changes to its parameter.

We know that the modulus function,

f(x)=∣x∣ is continuous but not differentiable at x=0.

So,

f(x)=∣x∣+∣x−1∣+∣x−2∣+∣x−3∣+∣x−4∣ is continuous but not differentiable at x=0,1,2,3,4.

Mr. Keith's semimonthly salary is $16183.25.

What is rounded to the nearest cent?

If the number is five or higher and is to the right of the full cents, increase the cents by one. The cents should remain the same if the number is four or less.

For instance: $143.864. Consider the last digit, 4, since it is less than 5 and the cents should remain the same. Rounding up from $143.864 to $143.86.

Given that the annual salary of Mr. Keith is $64,733.

Semiannual means 4 times in yearly.

Thus divide whole salary by 4 to get semimonthly salary.

This is possible but fantastically unlikely. A simple random sample of 62 people from the county would be unlikely to produce a distribution of educational levels so different from the county-wide one. The chances of this happening are extremely small.

A simple random sample is a sample drawn from a population in such a way that each member of the population has an equal chance of being selected. In this case, the population is the county, and the sample is the group of 62 grand jurors. When a simple random sample is drawn, it is possible for the sample to be different from the population in various ways.

For example, the sample may have a different distribution of educational levels than the population. However, the larger the sample size is, the more likely it is that the sample will be representative of the population. In this case, the sample size of 62 is relatively small, so it is possible that the sample will be different from the population in terms of educational level. However, the chance of this happening is not very high, since the sample size is not very large.

Answer:

28° + 112° + 40° = 180°

Step-by-step explanation:

A Triangle has 3 angles that adds up to 180°

You are given 3 angles already so they must add up to 180°

Equation: n + 4n + 40° = 180°

Simple the equation.

Add the variable n together.

5n + 40° = 180°

Subtract 40 to both sides.

5n = 140°

Divide 5 to both side to solve for n.

n = 28°

Now plug n into our angles to have our angles in degree.

n = 28°

4n = 4×28° = 112°

40°

28° + 112° + 40° = 180°

Answer:

Step-by-step explanation:

The internal angles of a triangle sum 180°

n + 4n + 40 = 180

5n = 180 - 40

5n = 140

n = 140/5

n = 28

Check:

28 + 4*28 + 40 = 180

Answer:

46°

Step-by-step explanation:

As m<UYX and m<W is corresponding angle because X is the midpoint of UV and Y is the midpoint of UW, therefore

m<W = 46°

I hope my answer helps you.

Answer:

m<W = 46 degrees

Step-by-step explanation:

UX = UV/2  ==> This is because X is the mid-point of UV, dividing UV by 2

                           to make UX

UY = UW/2 ==> Y is the mid-point of UW, dividing UW by 2 to make UY

XY = VW/2 ==> Since X is the midpoint of UV and Y is the midpoint of UW,

                          segment XY is exactly in the middle of point U and              

                          segment VW, so segment XY is half of segment VW.

Since all sides of the small triangle(ΔUXY) are exactly half of all sides in the big triangle(ΔUVW), The corresponding angles in each triangle are equal to each other:
Hence,  m<UYX = m<UWV

m<UWV ==> m<W = 46 degrees  ==> since m<UYX=46, m<W = 46 as well
