Answer:
Step-by-step explanation:
Given :You have 36 apples to share with your friends.
To Find: if each friend gets exactly 2 apples, which equation could you use to solve for the number of friends ,n?
Solution :
Since there are 36 apples
There are n friends
Since each friend gets 2 apples.
So, n friends get apples= 2n
Thus equation becomes:
⇒
⇒
⇒
Thus there are 18 friends
Hence , Equation could you use to solve for the number of friends n:
5x-4=2x+8
+ 4 +4 Add 4 to both sides
5x=2x+12
-2x -2x Subtract 2x from both sides
3x=12
/3 /3 Divide by 3 on both sides
x=4
Answer:
1. True
2. False.
3. True.
Step-by-step explanation:
1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).
<em>Hence, for continuous probability distribution: probability = area</em>.
2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.
<em>Hence, it cannot be computed. </em>
3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.
<em>Hence, it can be computed. </em>
Answer:
it's inverse is:
f(x)^-1 = (x+10)/2
Step-by-step explanation:
f(x)= 2x -10
y= 2x -10 [ let f(x) be y]
interchange value of x and y
x=2y -10
(x+10) = 2y
y=(x+10)/2
f(x)^-1 = (x+10)/2
<span> x2 – 12x + 36 = 4
(x - 6)^2 = 2^2
x - 6 = 2
x = 8
-(x - 6) = 2
-x + 6 = 2
-x = -4
x = 4
