Answer:
B: 280
Step-by-step explanation:
The regression line predicts that when x equals 5:
In order to find the value for y, one must simply apply the following logarithmic property:
if : 
then: 
Applying it to this particular problem:
Therefore, the regression line predicts y will equal 280 when x equals 5.
y=5/6+3
I am not positive on this answer I am sorry if it is wrong
Answer:
10 SENIORS
Step-by-step explanation:
x=# of seniors
y=# of juniors
x+y=23, x=2y-7
- plug the value of x in the second equation into the first
- (2y-7)+y=23
- Remove parentheses
- 2y-7+y=23
- Combine like terms
- 3y-7=23
- Add 7 to BOTH sides
- 3y=30
- divide BOTH sides by 3
- 3y/3=30/3
- y=10
- There are 10 juniors in the class
- FINAL STEPS
- Plug y (which is 10) into the first equation
- x+y=23
- x+10=23
- subtract 10 from BOTH sides
- x=13
- Since X equals the number of seniors, there are 10 seniors in the class
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m of AB using the slope formula
m = 
with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(- 3, 2)
m = 
= 
= 0
A line with a slope of zero is a horizontal line, parallel to the x- axis.
Thus a line perpendicular to AB is a vertical line parallel to the y- axis.
The slope of a vertical line is undefined
Answer:
0.14
Step-by-step explanation:
When the game starts, either thee will be a hit or a miss.
The probability of hit = 0.3
Probability of miss = 0.7
Further, after a hit, the probability of hit = 0.3
And the probability of miss= 0.7
Continuing in this way, if we get 2 continuous miss, the game will terminate.
Hence,
the probability of game to terminate = Probability of first miss + Probability of second miss
= 0.7 +0.7
= 0.14
