Answer:
(0,-2)
Step-by-step explanation:
That point is the y intercept. (4/3,0) would be the x.
Answer:
the probability that a sample of the 35 exams will have a mean score of 518 or more is <em> 0.934 </em>or<em> 93.4%</em>.
Step-by-step explanation:
This is s z-test because we have been given a sample that is large (greater than 30) and also a standard deviation. The z-test compares sample results and normal distributions. Therefore, the z-statistic is:
(520 - 518) / (180/√35)
= 0.0657
Therefore, the probability is:
P(X ≥ 0.0657) = 1 - P(X < 0.0657)
where
- X is the value to be standardised
Thus,
P(X ≥ 0.0657) = 1 - (520 - 518) / (180/√35)
= 1 - 0.0657
= 0.934
Therefore, the probability that a sample of the 35 exams will have a mean score of 518 or more is <em>0.934 or 93.4%</em>.

Sorry I couldn't answer it, but I hope this helps :)
Expand
15x3=13x+5
subtract 3 from both sides
15x=13x+5-3
simplify 13x+5-3 to 13x+2
15x-13x+2
subtract 13 from both sides
15x-13x=2
simplify 15x-13x to 2x
2x=2
divide both sides by 2
x=1
Answer:
7 fishes
Step-by-step explanation:
Given the growth of the population of fish which is modeled by the exponential function:
Where:
t=time in weeks after release
b=growth rate of the fish
At t=0
The initial number, 
of fish which was released into the lake is 7.
