Answer:
P(5, 0 )
Step-by-step explanation:
Where the line crosses the x- axis the y- coordinate of the point P is zero.
Substitute y = 0 into the equation and solve for x
2x + 3(0) - 10 = 0 , that is
2x - 10 = 0 ( add 10 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus P = (5, 0 )
Your sister is 24. Your brother is 20. You are 15. Therefore, your sister will be 48 years old. I’m 87% sure I did this right. Lol, good luck.
$6462.5
Simple Interest = (Principal × Rate × Time) / 100
SI = (P×R×T) / 100
P = 5500
R = 3.5
T = 5
[substitute the values into the formula]
SI = (5500 × 3.5 × 5) / 100
SI = 96250 / 100
SI = 962.5
Total = Principal + Simple Interest
T = P + SI
T = 5500 + 962.5
T = 6462.5
The total value of the account after 5 years will be $6462.5
Answer:
a) Percentage of students scored below 300 is 1.79%.
b) Score puts someone in the 90th percentile is 638.
Step-by-step explanation:
Given : Suppose a student's score on a standardize test to be a continuous random variable whose distribution follows the Normal curve.
(a) If the average test score is 510 with a standard deviation of 100 points.
To find : What percentage of students scored below 300 ?
Solution :
Mean
,
Standard deviation 
Sample mean 
Percentage of students scored below 300 is given by,






Percentage of students scored below 300 is 1.79%.
(b) What score puts someone in the 90th percentile?
90th percentile is such that,

Now, 






Score puts someone in the 90th percentile is 638.
