Answer:
460 teens
Step-by-step explanation:
10% = 0.1
multiple 0.1 by 4600 to get the amount of teens at the game. You could also do 4600/10 = 460
The coordinate should be (4,5)
Answer:
Step-by-step explanation:
Let 'n' be any integer i.e. a number from the set {....., -3,-2,-1,0,1,2,3, ..... }
so 'n' can be termed as the variable here.
A number 'q' that can be divided by a a given number 'p' can be written as:
When divided by 'p' :
So, The number 'q' is completely divisible by 'p' leaving 'n' as the quotient.
Using this concept, let us solve the questions:
a) Using 'n' as the variable, a number that is divisible by 5 can be written as:
b) Using 'n' as the variable, a number that is divisible by 10 can be written as:
c) Using 'n' as the variable, a number that is divisible by 3 can be written as:
Answer:
C. Events E and A are independent
Step-by-step explanation:
we will verify each options
(a)
We can use independent events formula
P(B∩C)=P(B)*P(C)
we are given
P(B)=0.4
P(C)=0.25
P(B∩C)=0.05
now, we can plug these values into formula
and we get
0.05=0.4*0.25
0.05=0.1
we can see that left side is not equal to right side
so, this is FALSE
(b)
We can use independent events formula
P(D∩A)=P(D)*P(A)
we are given
P(D)=0.25
P(A)=0.6
P(D∩A)=0.1
now, we can plug these values into formula
and we get
0.1=0.25*0.6
0.1=0.15
we can see that left side is not equal to right side
so, this is FALSE
(c)
We can use independent events formula
P(E∩A)=P(E)*P(A)
we are given
P(E)=0.5
P(A)=0.6
P(E∩A)=0.3
now, we can plug these values into formula
and we get
0.3=0.5*0.6
0.3=0.3
we can see that both sides are equal
so, this is TRUE
(d)
We can use independent events formula
P(D∩B)=P(D)*P(B)
we are given
P(D)=0.25
P(B)=0.4
P(D∩A)=0.15
now, we can plug these values into formula
and we get
0.15=0.25*0.4
0.15=0.1
we can see that left side is not equal to right side
so, this is FALSE
Step-by-step explanation:
x= 2 y = 10
x= 0 y = 8
x= 4 y = 12
