Graph the line that has a slope of 1/9 and includes the point (0,9).

1 answer:

5 0

To graph a slope and the points, you first have to find the 9 in the y-axis, and you mark a dot on it (if you want).

Then on that point, you go up one unit in the graph, then go 9 units right. Continue, until it reaches the end of the graph.

And, you do the opposite way. Go to the y-intercept, then go 1 unit down, and 9 units left.

And that’s how you graph it. Hope it helps :)

Find the next three terms in each sequence. Then write an equation for the nth term of the

Ne4ueva [31]

Step-by-step explanation:

a) clearly, the sequence is created by subtracting 12 from one term to the next.

so, d = -12

a (= a1) = -5 (the first term is the start value)

the next 3 terms are then

-41, -53, -65

a28 = -5 + 27×-12 = -329

b) the sequence is created by adding 6 from term to term.

so, d = 6

a (= a1) = 8

the next 3 terms are

26, 32, 38

a77 = 8 + 76×6 = 464

Find the second, fourth, and eleventh terms of the sequence A(n) = 5 + (n - 1)(-3)

klio [65]

Answer:

2nd: 2

4th: -4

11th: -25

Step-by-step explanation:

When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:

A(2) = 5 + (2 - 1)(-3)

A(2) = 5 + (1)(-3)

A(2) = 5 - 3

A(2) = 2

To get the 4th term you substitute in 4:

A(4) = 5 + (4 - 1)(-3)

A(4) = 5 + (3)(-3)

A(4) = 5 - 9

A(4) = -4

And we do the same for the 11th term:

A(11) = 5 + (11 - 1)(-3)

A(11) = 5 + (10)(-3)

A(11) = 5 - 30

A(11) = -25

Answer:

38.46% probability that the sample proportion will NOT be between 0.60 and 0.73

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

For a proportion p in a sample of size n, we have that $\mu = p, \sigma = \sqrt{\frac{p(1-p)}{n}}$
