What is an equation of the line that passes through the points (-4,1) and (4,4)?
Ray Of Light [21]

Answer:

y = \frac{3}{8} x +  \frac{5}{2}

Step-by-step explanation:

☆Remember: m =  \frac{y_2 - y_1}{x_2 - x_1}

☆Remember: Slope-intercept form -> y = mx + b

☆Now. We first need to find the slope.

m =  \frac{4 - 1}{4 -  (- 4)}  =  \frac{3}{8}

☆Now the y-intercept.

y =  mx + b \\  \\ 4 =  \frac{3}{8} (4) + b \\  \\ 4 =  \frac{3}{2}  + b \\   \frac{ -  \frac{ 3}{  2} =  -  \frac{ 3}{ 2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  }{ \frac{5}{2} = b }

Calculate the length of the unknown side of this right angled triangle
azamat

Answer:

12.04

Step-by-step explanation:

Well to solve for the unknown side "c" we need to use the Pythagorean Theorem formula,

a^2 + b^2 = c^2

We already have a and b which are 8 and 9 so we plug them in.

(8)^2 + (9)^2 = c^2

64 + 81 = c^2

145 = c^2

c = 12.04 rounded to the nearest hundredth.

<em>Thus,</em>

<em>the unknown side is about 12.04.</em>

<em />

<em>Hope this helps :)</em>

In a survey sample of 83 respondents, the mean number of hours worked per week is 39.04, with a standard deviation of 11.51. Cal
soldier1979 [14.2K]

Given that,

Sample size= 83

Mean number= 39.04

Standard deviation= 11.51

We know the critical t-value for  95% confidence interval which is equal to 1.989.

We also know the formula for confidence interval,

CI=( mean number - critical t-value*standard deviation/(sample size)^(1/2), mean number + critical t-value*standard deviation/(sample size)^(1/2))

So, we have

CI= (39.04 - 1.989*11.51/83^(1/2), 39.04 + 1.989*11.51/83^(1/2)

CI= (39.04 - 2.513,39.04 + 2.513)

CI= (36.527,41.553)

Therefore, 95% confidence interval for these data is (36.527,41.553), and this result interpret that the true value for this survey sample lie in the interval (36.527,41.553).

Solve equation<br><br> -2 • 4/5 = -3 1/2 • n
kogti [31]
16/155 = n


explanation

A linear equation is an equation of a straight line. To solve linear equations, it is important to keep the following key concepts in mind:

Maintain balance of the equation by applying the same operations to both sides of an equation

Isolate for the variable by collecting like terms

Use inverse operations to rearrange an equation


to show your work

-8/ 5 = -31/2 • n
- 8/5 = -31n/2
2(-8/5) = 2 • -31/n
-16/5 = -31n
-16/5 / -31 = -31n/31
16/155 = n
