First, we need to know what is the general equation of the slope-intercept form. It is expressed as follows:

y = mx + b

where m is the slope and b is the y-intercept. Therefore, having a slope of -5 and a y-intercept of -1, the equation of the line should be:

y = -5x - 1

Slope intercept form : y = mx + b

the slope is represented by m....so m = -5
the y intercept is represented by b....so b = -1

now we sub
y = mx + b
y = -5x + (-1) or y = -5x - 1 <===

Answer:

To answer you question, we need the confidence internals formula, μ±Zc*(σ/ $\sqrt{N}$ ); N is the 20 psychology students, 0.5 the desviation standar and 4.3 is the medium based on national data, every fact in years.

Step-by-step explanation:

You need to consult the Zc value, you can find this table attached in this question; for 95%, we have a Zc value of 1.96.

Next step replace values: 4.3±1.96*(0.5/ $\sqrt{20}$ ) = 4.3±0.22 (rounding the result)

So, the confidence interval are:

4.08cm≤X≤4.52cm

Dimensions of a building are 740 feet by 800 feet. If 1 inch represents 8 feet, what are the dimensions of the building on the d

Scrat [10]

The dimensions of the building on the drawing would be 92.5 inches by 100 inches.
Explanation:
if 1 inch = 8 feet, then you just subtract 8 by 740 and 800 to get the dimensions.

First set up the equation to find answer: y=7-x. Then add it to the variable. 3x-1(7-x)=1. So that makes it 3x+-7+-1=1. Add like terms -7+-1=-8, so 3x+-8=1. Now to find x just switch the 8 to the other side. So you end up with 3x=9 since when you take away a number from one side you need to use the opposite value so adding 8 to -8 will cancel it out, then add it to the other, then just divide. 9/3=3, from here just substitute to find y. y=7+3. y=10. The answer is x=2 and y=5. I hope I helped!
