A line has a slope of 9 and a y-intercept of 2. What is its equation in slope-intercept form?
kakasveta [241]

Answer:

y=9x+2

Step-by-step explanation:

The standard form for a linear equation is y=mx+b. m=9 since it is slope and b=2 which is the y intercept. So the equation would be y=9x+2.

the equation a equals 1 half b h, where b represents base and h represents height, is used to find the area of a .
NikAS [45]

The formula for b from the given area is equal to (2A / h).

As given in the question,

Formula to find area of a triangle is equal to A = (1/2) b h

b represents the base of the triangle

h represents the height of the triangle

A = (1/2) b h

Multiply both the side by 2 in area formula

2A = b h

Divide both the side by h

b = (2A) / h

Therefore, the formula for b from the given area is equal to (2A / h).

The complete question is:

The formula A = (1/2)b h represents the area of a triangle where A represents the area, b is the base of the triangle and h is the height of the triangle. 1. Solve this formula for b.

Answer:

Margin of error  for a 95% of confidence intervals is 0.261

Step-by-step explanation:

<u>Step1:-</u>

 Sample n = 81 business students over a one-week period.

 Given the population standard deviation is 1.2 hours

 Confidence level of significance = 0.95

 Zₐ = 1.96

Margin of error (M.E) = \frac{Z_{\alpha  }S.D }{\sqrt{n} }

Given n=81 , σ =1.2 and  Zₐ = 1.96

<u>Step2:-</u>

<u />Margin of error (M.E) = \frac{Z_{\alpha  }S.D }{\sqrt{n} }<u />

<u />Margin of error (M.E) = \frac{1.96(1.2) }{\sqrt{81} }<u />

On calculating , we get

Margin of error = 0.261

<u>Conclusion:-</u>

Margin of error  for a 95% of confidence intervals is 0.261
