Please help me determine the equation of the line in slope intercept form and show all work. A line that is perpendicular to the

Airida [17]

Answer:

y=-2x+160

Step by Step:

The equation of a line can be determined using the point slope formula:

y-y1=m (x-x1)

To make a substitution, we must ensure we have the correct information. The question gives:

y1=60

x1=50

y=1/2x+10 This is the formula of a line that is perpendicular to the one we are trying to find.

It tells us that the gradient of the perpendicular line is 1/2. The gradient of the line we are trying to find can be found using m1×m2=-1 because we know that when lines are perpendicular, the product of their gradients must equal 1

So if we replace m1 with 1/2

1/2×m2=-1

m2=-2

We now have all the relevant information to make a substitution:

y-60=-2 (x-50)

expand brackets

y-60=-2x+100

rearrange to get in the form y=mx+b

y=-2x+160

I can't figure out the x-intercepts. Help. NO LINKS

zavuch27 [327]

Answer:

(-3,0)

Step-by-step explanation:

To find the x-intercept set y to 0,

x^2 + 6x + 9 = 0 Now you have a quadratic equation, so you can solve it

(x + 3)(x + 3 ) = 0

x + 3 = 0

x = -3

Suppose a set of test scores is appproximately bell-shaped, with a mean of 68 and a range of 54. (a) The minimum test score is a

liberstina [14]

Answer:

a.) Minimum test score = 41

Maximum test score = 95

b.)An approximate value of the standard deviation is 9.

Step-by-step explanation:

The given set of test scores is approximately bell shaped.

The mean of the test scores, $\mu$ = 68

The range of the data set = 54.

a.) i.) Minimum test score = $\mu - \frac{range}{2} = 68 - \frac{54}{2} = 68 - 27 = 41$

ii.) The maximum test score = $\mu + \frac{range}{2} = 68 + \frac{54}{2} = 68 + 27 = 95$

b.) From the 68-95-99.7 rule, also known as the Empirical rule, tell us that an approximation of the range is 3 standard deviations either way from the mean. So from this rule we can say that the minimum can also be found from $\mu - 3\sigma$ and the maximum can also be approximated as $\mu + 3\sigma$ .

From the above we can say that the range can be written as

$3\sigma - (-3\sigma) = range$

∴ $6\sigma = range$

∴ $\sigma = \frac{range }{6} = \frac{54}{6} = 9$

Therefore an approximate value of the standard deviation is 9.
