A student says that a correlation coefficient of −0.93 indicates that the two quantities of a data set have a weak correlation. Explain the error the student made.

Answers

Answer 1

Answer:

Step-by-step explanation:

Recall that correlation coefficients range from -1 to +1.  So, -0.93 is a strong negative relationship.  Two interpretations:  1) the correlation is actually very strong, and 2) the correlation is negative.  When the correlation is negative, the dependent variable DECREASES when the independent variable INCREASES.

Kimi’s dog gives birth to a litter of 4 puppies per year, on average. The relationship between time and the expected total number of puppies is shown on the graph. Which other ordered pairs would fall on this line? Select all that apply.
(0, 0)
(2, 6)
(3, 12)
(4, 14)

Answers

Answer:

(0,0) and (3,12)

Step-by-step explanation:

The ordered pairs that would fall on the line are (0, 0), (1, 4), (2, 8), (3, 12), and (4, 16).

As shown in the graph,

x-axis represents the number of years

y-axis represents the number of puppies.

The slope of the line is 4, which means that for every 1 year that passes, the number of puppies increases by 4.

The y-intercept of the line is 0, which means that if there are 0 years, then there are 0 puppies.

The ordered pairs (2, 6) and (4, 14) do not fall on the line because they do not follow the slope of the line.

For example, in the case of (2, 6), the number of puppies should be 8, not 6.

Therefore, the only ordered pairs that would fall on the line are (0, 0), (1, 4), (3, 12), and (4, 16).

Answers

Answer:

summary

Step-by-step explanation:

Answer: Choice C

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)

============================================

Explanation:

The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.

The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,

slope = rise/run = (change in y)/(change in x)

Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.

The first five terms in a pattern are shown below.

-0.5, -0.25, 0, 0.25, 0.5, …

If the pattern continues, which expression can be used to find the nth term?

0.75n − 1.25
−0.25n − 0.25
0.25n − 0.75
−0.5n + 0.25

Answers

Answer:

I think this answer is A.

Step-by-step explanation:

I think this because when you subtract 0.5-0.25 you get 0.25. So you would add it to whatever comes next until you get to the 9th term. Then you would be somewhere around the ones place. :)

In the given pattern, the expression that can be used to find the nth term of the sequence is T(n)=0.25n-0.75. The correct option is C.

What is an Arithmetic Sequence?

An arithmetic sequence is a sequence in which the difference between any two consecutive terms of the sequence is equal.

Tₙ = a₁ + (n-1)r

where,

Tₙ is the nth term of the sequence,

a₁ is the first term of the sequence,

r is a common difference between every two terms.

Since the given sequence is in an arithmetic progression, therefore, the common difference between any two consecutive terms in the sequence are,

Difference, d = -0.25 - (-0.5)

                      = -0.25 + 0.5

                      = 0.25

Also, the first term of the sequence is -0.5. Therefore, using the formula of nth for an arithmetic sequence, we can write,

nth term = a₁ + (n - 1)d

              = -0.5 + (n - 1)0.25

              = -0.5 + 0.25n - 0.25

              = 0.25n - 0.5 - 0.25

              = 0.25n - 0.75

Hence, in the given pattern, the expression that can be used to find the nth term of the sequence is T(n)=0.25n-0.75.

On a coordinate plane, a graph titled Chad's Cards has Damage on the x-axis and Defense on the y-axis. Points (1, 2), (2, 4), (3, 6), and (4, 8) are plotted.
Chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a Catcher card.
Chad should not have included the values (1, 2) and (3, 6) because the ratio would be different for these points.
Chad should have changed the axes for the Infield and Pitchers cards so it was the same order as the table.
Chad needs to switch the order of each (x, y) value to show the decreasing values of the Pitchers cards.
