Answer:

The slope of the line between the points (2,-1) and (5,-3) is $m=-\frac{2}{3}$

Therefore $m=-\frac{2}{3}$

Step-by-step explanation:

Given that the line between the points (2,-1) and (5,-3)

To find the slope of the line between the points (2,-1) and (5,-3) :

The formula for slope is $m=\frac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)$ , $(x_2,y_2)$ be the given points (2,-1) and (5,-3) respectively

Now substitute the values of the points in the formula

$m=\frac{-3-(-1)}{5-2}$

$=\frac{-3+1}{3}$

$=\frac{-2}{3}$

Therefore $m=-\frac{2}{3}$

The slope of the line between the points (2,-1) and (5,-3) is $m=-\frac{2}{3}$

How do you do this?<br> Please help

Assoli18 [71]

Answer:

36 pencils

Step-by-step explanation:

Let h and p represent the number of highlighters and the number of pencils, respectively.

Then h + p = 45, and h = 45 - p.

Tom paid a total of $30 for these supplies, with ($2/highligher)(h) + ($0.333/pencil) adding up to that amount.

substituting 45 - p for h in 2h + 0.333p = 30, we get:

2(45 - p) + 0.333p = 30, or

90 - 2p + 0.333p = 30

Combine the constants: 60 = 2p - 0.333p, or 60 = 1.667p

Then p = 60/1.667 = 35.9928, or 36.

Tom bought 36 pencils for $12, and 45-36, or 9, highlighters for $18, for a total purchase of $30. This shows that these calculations are correct.

ddd [48]

Answer:

For 90% CI = (0.428, 0.572)

For 98% CI = (0.399, 0.601)

The confidence interval (and Margin of error) reduces when 90% confidence level is used compared to when 98% confidence level is used.

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

p+/-z√(p(1-p)/n)

Given that;

Proportion p = 66/132 = 0.50

Number of samples n = 132

Confidence level = 90%

z(at 90% confidence) = 1.645

Substituting the values we have;

0.50 +/- 1.645√(0.50(1-0.50)/132)

0.50 +/- 1.645√(0.001893939393)

0.50 +/- 0.071589436011

0.50 +/- 0.072

(0.428, 0.572)

The 90% confidence level estimate of the true population proportion of students who responded "yes" is (0.428, 0.572)

For 90% CI = (0.428, 0.572)

For 98% CI = (0.399, 0.601)

The confidence interval (and Margin of error) reduces when 90% confidence level is used compared to when 98% confidence level is used.
