Answer:
Step-by-step explanation:
<h3>Given </h3>
- Segment RS and midpoint M(-1, 13)
- S = (4, 12)
- R = ?
<h3>Solution</h3>
<u>Midpoint formula</u>
- x = (x1 + x2)/2 and y = (y1 + y2)/2
<u>Coordinates of point R</u>
- -1 = (4 + x)/2 ⇒ 4 + x = -2 ⇒ x = -6
- 13 = (12 + y)/2 ⇒ 12 + y = 26 ⇒ y = 14
- R = (-6, 14)
Answer:
option 4
The value is not unusual.
Step-by-step explanation:
If the probability of revenue between $747.89 and $818.68 million is low i.e. less than 5% then we can say that it would be unusual for a randomly selected company to have a revenue between $747.89 and 818.68 million.
We are given that revenue found to follow a bell curve. Also, we are given that mean=815.425 and standard deviation=22.148.
P(747.89<x<818.68)=?
P((747.89-815.425)/22.148<z<(818.68-815.425)/22.148)=P(-3.05<z<0.15)
P(747.89<x<818.68)=0.4989+.0596=0.5585
Thus, the probability for a randomly selected company to have a revenue between $747.89 and 818.68 million is not low and so the value is not unusual.
Put the rest of the info too so ppl could solve it lolll
Answer:
10 people didn't answer the servey
Step-by-step explanation:
servey=80 people
70= answered the servey
so we should take the difference:-
80–70= 10
Hope I got the right answer!
X² - 15 x + 36 = 0
x² - 12x - 3x + 36 = 0
x( x - 12) - 3( x - 12) = 0
(x - 3)( x - 12) = 0
x - 3 = 0
x = 3
or
x - 12 = 0
x = 12
The solutions are 3 and 12
