Find the slope of the line that passes through points (2, 8) and (1, 3)

Paha777 [63]

Answer:

Your slope would be 5

Step-by-step explanation:

Since we know 2 points we'd use the formula

$M=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

$X_{1} = 2$

$X_{2}=1$

$y_{1}=8$

$Y_{2}=3$

So your equation would be

$M=\frac{3-8}{1-2}$

Than you would subtract each of them leaving you with this:

$M=\frac{-5}{-1}$

When you divide the two negative numbers that would leave you with your slope, which is 5.

-5 ÷ -1 = 5

I hope this help.

andreev551 [17]

Answer:

Step-by-step explanation:

log 100

Rewriting 100 as 10 ^2

log 10^2

We know that log a^b = b log a

2 log 10

log 10 = 1 since log 10 (10) =1

2 (1) =2

A scale drawing of a soccer field is 6 inches long. The actual soccer field is 300 feet long. Which of the following represents

sveticcg [70]

Answer: IT IS BBBB

Step-by-step explanation:

In the figure attached, the complete question is shown.

Originally the scale is 1 inch: 12 yards, the width is 6 inches, that is, 6*12 = 72 yards, and the length is 9 yards, that is, 9*12 = 108 yards

If the scale is 1 inch: 36 yards, then 72 yards are:

1 inch / x inches = 36 yards / 72 yards

x = 72/36 = 2 inches

which represents the new width.

And 108 yards are:

1 inch / x inches = 36 yards / 108 yards

x = 108/36 = 3 inches

which represents the new length.

A clinical psychologist wants to test whether experiencing childhood trauma affects one's self-efficacy in adulthood. He randoml

Verdich [7]

Answer:

Step-by-step explanation:

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = 152.5

For the alternative hypothesis,

µ ≠ 152.5

This is a two tailed test.

Since no population standard deviation is given, the distribution is a student's t.

Since n = 231

Degrees of freedom, df = n - 1 = 231 - 1 = 230

t = (x - µ)/(s/√n)

Where

x = sample mean = 148.9

µ = population mean = 152.5

s = samples standard deviation = 27.4

t = (148.9 - 152.5)/(27.4/√231) = - 2

We would determine the p value using the t test calculator. It becomes

p = 0.047

Since alpha, 0.05 > thanthere sufficient evidence to conclude that the self-efficacy of adults who have experienced childhood trauma differs from that in the general population of individuals the p value, 0.047, then we would reject the null hypothesis. Therefore, At a 5% level of significance, there is sufficient evidence to conclude that the self-efficacy of adults who have experienced childhood trauma differs from that in the general population of individuals
