Answer:

m = \frac{1}{2}

Step-by-step explanation:

Two points are ( 8, 0 ) and  (0 , - 4)

              slope \ , \ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -0}{0-8}=\frac{-4}{-8} = \frac{1}{2}

6=-w/8. How do I solve this equation . What is w
VLD [36.1K]
To “cancel out the the 8 you would multiply by 8 on both sides and then you would be left with 48=-w. With that you would find the opposite of 48 and w and w=-48

What is the equation in point slope form for the line that is parallel to y=-8x-12 that contains the point (-3,3)
belka [17]

Answer:

The equation of a parallel line in point-slope form would be y - 3 = -8(x + 3)

Step-by-step explanation:

To find this, we must first note that the original slope is -8. Parallel lines have the same slope, so we know that the new line will also have the slope of -8.

Given this information, we can use the point and slope and put them into the base form of point-slope form.

y - y1 = m(x - x1)

y - 3 = -8(x - -3)

y - 3 = -8(x + 3)

A. <br> 0.643<br><br> B. <br> 0.933<br><br> C. <br> 0.600<br><br> D. <br> 0.321
PolarNik [594]

Answer:

0.321 (Answer D)

Step-by-step explanation:

Note that the event "A and Y" happens 9 times.  That's 9 times out of (6+9+8+5) outcomes, or 28 outcomes.

Hence, P(A and Y) = 9/28, or 0.321 (Answer D)

The t value for a 99% confidence interval estimation based upon a sample of size 10 is
Aliun [14]
Answer:
For a sample size of 10, the t-value is about 3.25 (from tables) at a 99% confidence interval.

Explanation:
When the standard deviation for the population is not known, the confidence interval estimate for the population mean is performed with the Student's t-distribution.
The confidence interval for the mean is calculated as
(\Bar{x}- t\frac{s}{\sqrt{n}} , \, \Bar{x}+ t\frac{s}{\sqrt{n}}
where
 \Bar{x} = sample mean,
s = sample standard deviation,
t = t-value (provided in tables),
n =  sample size.

When reading the t-value, (n-1) is called the df or degrees of freedom.
