Step-by-step explanation:
A triangle has vertices at (3, 3), (6, 15), and (3, -3). What are the coordinates of the orthocenter?
A. (-69, 15)
B. (3.5, 3)
C. (4.2)
D. (9, 0)
Answer:
The answer would be A) (-69, 15)
Solution:
Finding 1st and 2nd
m = (y2 - y1)/(x2 - x1)
m = (15 - 3 )/(6 - 3)
m = 12/3
y = 4x + b
3 = 3(3)+b
3=9+b
-9 -9
-6=b
Finding 3rd
repeat the above process for 1 and 2, so now use 2 and 3 in the equation.
m = -9/3
m=-3
y=-3x+b
15=-3(6)+b
b=-3

7) A deck of cards has 4 yellow, 5 orange, and 5 blue cards. You pick 4 cards from the deck. Cards are
A not returned to the deck after they are picked.
P(four orange cards in a row)
Answer:
Please Brainliest
2/13
Step-by-step explanation:
So firstly, know that there are 13 cards in the deck (3 + 6 + 4).
Therefore, the probability of drawing a green is 4/13.
After you draw the green card, there will be 12 cards left. Therefore, the probability of drawing a purple card next is 6/12.
To find compound probability, multiply the probabilities of the two separate events happening together:
4/13 * 6/12
= 2/13

Determine which function has the greater rate of change, if either.
A. Function B has a greater rate of change because it's rate of change is 4/3
B. Function A has a greater rate of change because it's rate of change is 4/3
C. Neither function has a greater rate of change because their slopes are both 4/3
EXPLAIN
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality

The 99% confidence interval for the population mean will be x± [tex]\frac{2.58 s}{\sqrt{n} }[/tex].
What is a confidence interval?
A confidence interval is a set of calculations for an unrecognized parameter that is specified as a range with a lower and upper bound.
If we take an n-sample from a normal population and wish to estimate the population mean, the confidence interval for the mean is:
[tex]\bar x[/tex]±[tex]Z_\frac{\alpha }{2} \times \frac{s}{\sqrt{n} }[/tex]
The level of significance is found by;
[tex]\rm \alpha =1- \ condifidence\ level \\\\\ \rm \alpha =1- 0.99 \\\\\ \rm \alpha = 0.001[/tex]
The value of z is
[tex]\rm Z_{\frac{\alpha}{2}} = \rm Z_{\frac{0.01}{2}} = Z_{0.005}=2.58[/tex]
Hence the 99% confidence interval for the population mean will be x± [tex]\frac{2.58 s}{\sqrt{n} }[/tex].

Which of the following differences could not give a distance between two points on a number
line? Explain why.
(1) 19-7
(3) -12 -(-7)
(2) -3-(-18)
(4) 14-(-6)
Answer:
Choice: (3) -12 -(-7)
Step-by-step explanation:
The distance between two points is by definition a positive number. If we wanted to know the distance between points 5 and 8, we should use the absolute value of the difference:
d=|5-8|=8-5=3
The same applies to negative points like -2 and -7:
d=|-2+7|=|2-7|=7-2=5
The only choice that does not result in a positive distance is (3) because
-12-(-7)=-12+7=-5
Thus this is not a distance between two points on a number line.
Choice: (3) -12 -(-7)
