Hello :
(3p)² =3²×p² = 9p²
The answer is D. because first you got solve the problem.
y=2.5x
(turn y to 0)
0= 2.5x
÷2.5 ÷2.5
_________
0=x
So we got one answer (0,0)
y=2.5x
(turn x to 0)
y= 2.5(0)
y=2.5
(2.5, 0)
When you do (0,0) (2.5,0) on the graph it will look like D.)

Answer:
Step-by-step explanation:
Assuming a normal distribution for the distribution of the points scored by students in the exam, the formula for normal distribution is expressed as
z = (x - u)/s
Where
x = points scored by students
u = mean score
s = standard deviation
From the information given,
u = 70 points
s = 10.
We want to find the probability of students scored between 40 points and 100 points. It is expressed as
P(40 lesser than x lesser than or equal to 100)
For x = 40,
z = (40 - 70)/10 =-3.0
Looking at the normal distribution table, the corresponding z score is 0.0135
For x = 100,
z = (100 - 70)/10 =3.0
Looking at the normal distribution table, the corresponding z score is 0.99865
P(40 lesser than x lesser than or equal to 100) = 0.99865 - 0.0135 = 0.98515
The percentage of students scored between 40 points and 100 points will be 0.986 × 100 = 98.4%
