Answer:
1 ÷ 7
Step-by-step explanation:
A fraction represents a division with the numerator divided by the denominator, then
≡ 1 ÷ 7
$10.50
14÷4= 3.5 so, 3.5 x 3 = 10.50
Answer:
Not independent.
Step-by-step explanation:
Given that P(A)=0.25 , P(B)=0.2 , and P(A and B)=0.04
To check whether A and B are independent.
Two events are independent if
P(A/B) = P(A) or P(B/A) = P(B) or P(AB) = P(A) P(B)
if any one of the above three is true also, the two events would be independent.
Let us find out first one
P(A/B ) = P(AB)/P(B) (as per conditional probability formula)
= 0.04/0.2=0.2
But P(A) = 0.25 and not equals P(A/B)
Hence we can conclude that A and B are not independent
because P(A/B) not equals P(A)
Answer:
The answer to your question is 1.- (-3, 4) 2.- (3, 1) None of the choices
Step-by-step explanation:
1.- The solution of a system of equation by the graph method is the point in which the lines cross. In this graph we observe that this point is approximately
(-3, 4).
2.-
Equation 1 x + y = 4
Equation 2 x - y = 2
Solve by the combination method
x + y = 4
x - y = 2
2x 0 = 6
2x = 6
Solve for x
x = 6/2
x = 3
Substitute x in equation 1 to find y
3 + y = 4
Solve for y
y = 4 - 3
y = 1
Solution (3, 1)
Answer:
0,5X + (-2), but you have to solve it... I give you the equation.
Step-by-step explanation:
In part A you have to find the equation of the line, so you do end - origin and you'll find m. I can only help you with the first one.
so:
(8,2) and (10,3)
(10-8,3-2) = (2,1)
V2/V1= 1/2= 0,5=m (slope of the line)
y= mx+n (change y, x and m with the ones above)
2= 8·0,5+n
2= 4+n
n= 2-4=-2
the equation is: 0,5X + (-2) and then you just have to change x in both equations, the second one is the h(x) adn it will give you the answer to A.
I hope I'm being helpful..!!!
