Make x the subject of y=x/3
Answers
This simply means moving everything possible thing off x and isolate it.
y=x/3
We see x is stuck with a divide by 3 so we need to get rid of that by multiplying by 3 on both sides.
y*3=x/3*3
switch left and right side and simplify
x=3y
Done! as simple as that.
Our only step to do so is to multiple both sides by 3, getting rid of the fraction x was trapped in, making it 3y=x
To make it easier to understand, we can just flip it and say x=3y, but both answers work.
Alia buys a computer. The original price of the
computer is $379.99. She uses a coupon for 15%
off any item. She must pay 6.75% sales tax on the
sale price. How much money will Alia spend on the
computer? (Hint....tax goes on the sales price!)
Answers
Answer:
$344.79
Step-by-step explanation:
379.99 decrease 15% =
379.99 × (1 - 15%) = 379.99 × (1 - 0.15) = 322.9915
322.9915 increase 6.75% =
322.9915 × (1 + 6.75%) = 322.9915 × (1 + 0.0675) = 344.79342625

The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking. Wow a statement that describes how the distance that you travel is determined. Then identify the independent and dependent variables if this function.
Answers
Answer:
The maintained speed while hiking= 3 miles per hour
Let t be the time which represent the independent variable.
Also we know that Distance= Speed × Time
⇒ Distance traveled while hiking=3 ×t=3t
Let h represent the distance function in miles, and h(t) the dependent variable.
Then h(t)=3t
When we put t=4
Then h(4)=3×4 =12 miles.

Solve for x. 6/x+ 2/5 = 8
Answers
Answer:
15/19
Step-by-step explanation:
6/x +2/5 = 8
(multiply through by x)
6 + 2x/5 = 8x
(minus 8x from both sides)
-38x/5 + 6 = 0
(subtract 6 from both sides)
-38x/5 = -6
(times by -1)
38x/5 = 6
Times 6 by 5 and then divide by 38.
=15/19

Why should the sum of the probabilities in a probability distribution always equal to 1?
Answers
Answer:
If u add probabilities of all possible outcomes that should be one, because classical definition of probability is number of possible out comes divided by total number of outcomes. When you add all probabilities numerator and denominator are equal so answer is one.
Answer:
The total probability of a set of related events sums up to 1 because the probability of each individual event in the set is a fraction of the whole. For example, suppose you flip a fair coin a large number of times.
