Answer:
Answer: y - 8 = x - 7
Step-by-step explanation:
SOLUTION:
General equation : (y2 - y1)/(x2 - x1) = slope
.
Substitute slope = 1 into the equation:
(y2 - y1)/(x2 - x1) = 1
.
Substitute (7, 8) into the equation:
(y - 8)/(x - 7) = 1
.
Cross multiply:
y - 8 = x - 7
.
Answer: y - 8 = x - 7

I play a gambling game in which I will win different amounts of money with different likelihood's. Suppose that I win X dollars with a probability of P(X) (if C is negative I am losing money). The distribution is as follows: what is the appropriate value of P?
Answers
Answer:
[tex]p = 0.05[/tex]
Step-by-step explanation:
Given
See attachment for the distribution
Required
Find p
To find p, we make use of:
[tex]\sum P(x) = 1[/tex]
So, we have:
[tex]0.50 + 0.25 + 0.13 + 0.07 + p = 1[/tex]
[tex]0.95 + p = 1[/tex]
Make p the subject
[tex]p = 1 - 0.95[/tex]
[tex]p = 0.05[/tex]

Find the volume of the cylinder.
Either enter an exact answer in terms of
π
πpi or use
3.14
3.143, point, 14 for
π
πpi.
Answers
Answer:
Solution :-Radius is 3
Height is 2
So,
Volume = πr²h
Volume = 3.14 × (3)² × 2
Volume = 3.14 × 9 × 2
Volume = 3.14 × 18
Volume = 56.5 units²
Answer: 56.52
Step-by-step explanation:
You can get a volume of a cylinder by multiplying pie which is 3.14 by radius squared multiplied the height...
The equation is Volume = πr²h
Or in simpler terms:
3.14 × radius ×radius × height
So the final equation is:
3.14 × 3² × 2
=56.52

1. To determine if "A" students tend to sit in a particular part of the classroom, a teacher recorded the locations of the students who received grades of A. He found that 17 sat in front, 9 sat in the middle, and 5 sat in the back of the classroom, when testing the assumption that the "A" students are distributed evenly throughout the room, he obtained the test statistic of x2 = 7.226. If using a 0.05 significance level, is there sufficient evidence to support the claim that the"A" students are not evenly distributed throughout the classroom? Then state the conclusion.

find the equation of the line passing through points (-4,2) and (1,-6)
Answers
Answer:
y + 6 = (-8/5)(x - 1) in point-slope form
Step-by-step explanation:
Moving from the 1st point to the first, we see that x (the 'run') increases by 5 from -4 to 1, and y (the 'rise') decreases by 8. Thus, the slope of the line through these two points is m = rise / run = -8/5
Now we have two points on the line, plus the slope. Let's write out the point-slope formula for the equation of a straight line:
y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
Here, using the point (1, -6), we obtain:
y + 6 = (-8/5)(x - 1) in point-slope form

A trout swam at a steady speed for 1.5minutes. It swam 9,900 centimeters in that time. What was its speed?
Answers
Answer:
6,600 cm per minute
Step-by-step explanation:
I got 6,600 by taking 9,900 divided by 1.5 minutes because it took the trout 1.5 minutes to swim 6,600 cm. 9,900/1.5= 6,600. So, the trouts was swimming at a speed of 6,600 cm per minutes.

Answers
Answer:
(0.1753 ; 0.2447)
Step-by-step explanation:
Using the relation :
Confidence interval :
p ± margin of error
p = 0.21
1 - p = 0.79
n = 530
Zcritical at 95% confidence level = 1.96
Margin of Error : Zcritical * sqrt[(p(1-p))/n]
1.96 * sqrt[(0.21(0.79))/530]
1.96 * 0.0176923 = 0.0346769
Margin of Error = 0.0346769
Lower boundary = 0.21 - 0.0347 = 0.1753
Upper boundary = 0.21 + 0.0347 = 0.2447
Confidence interval :
(0.1753 ; 0.2447)
