Answer:
the probability that exactly 1 received a special accommodation is 0.3079
Step-by-step explanation:
Step 1: define the variable
x= the number of students who received a special accommodation.
Step 2: define the distribution of this variable
x ~ binomial distribution ( p=0.02, n=25)
this is because x is the number of succes in 25 trials.
Step 3: using the binomial distribution formula
P(x=1)= (25C1)*(0.05^1)*(1-0.05)^(25-1)=0.3079
where (25C1) is a combination
Answer:
y = - 2x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ← m is the slope
To calculate m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (0, 0) ← 2 points on the line
m = = = - 2
y = - 2x ← equation of line
Answer:
12x²y² +2xy -2
Step-by-step explanation:
The distributive property is used to multiply polynomials.
(3xy -1)(4xy +2) . . . . . . . . . . . . . given
= (3xy)(4xy +2) -1(4xy +2) . . . . multiply the 2nd by the terms of the 1st
= (12x²y² +6xy) +(-4xy -2) . . . . here are those products
= 12x²y² +2xy -2 . . . . . . . . . collect terms (6xy-4xy = 2xy)
