The average of x and t is y. If s = 2y, what is the average of s, x,
and t in terms of y?
А. Зу
B. 2y
C. 5y/3
D. 4y/3
E. y
Answers
===================================================
Explanation:
First focus on the fact that "the average of x and t is y". This means
(x+t)/2 = y
We basically add x and t, then divide by 2 to get the average y
--------
We are then told that s = 2y, so we double the average
s = 2y
s = 2(x+t)/2
s = x+t .... notice the 2's cancel each other out when dividing
s turns out to be the sum of x and t, which is fitting I think
---------
Now find the average of s, x, and t. You'll add the three values and divide by 3
(s+x+t)/3
(s + (x+t))/3
(s + s)/3 .... replace x+t with s
2s/3
2(2y)/3 ... plug in s = 2y
4y/3
The average of s, x, and t in terms of y is 4y/3. The correct option is D. 4y/3
Calculating AverageFrom the question, we are to determine the average of s, x, and t in terms of y
From the given information
The average of x and t is y
That is,
(x+t)/2 = y
∴ x + t = 2y
Also,
s = 2y
The average of s, x, and t is
(s + x + t) / 3
Putting the values of x + t and s into the above expression, we get
(2y + 2y)/3
This becomes
4y/3
Hence, the average of s, x, and t in terms of y is 4y/3. The correct option is D. 4y/3

A population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, which function represents the number of caribou in the forest in t years?
Answers
Answer:
P(t) = 258( 1 + 6%)^t
Step-by-step explanation:
Given that the population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, the function representing the number of caribou in the forest in t years will be
P(t) = 258( 1 + 6%)^t
Since it is increasing, it will be 1 + 6%
Where P(t) is the function representing the population after t years.
258 is the current or initial population.

A machine is used to fill each of several bags with 16 ounces of sugar. If the bag
weights 0.3 ounces more or less than the desired weight, the bag is rejected. Write
this equation to find the heaviest and lightest bag the machine will approve.
Answers
Answer: 15.7oz < M < 16.3oz
Step-by-step explanation:
The average mass of each bag will be 16oz
If the bag weighs 0.3 oz more or less than 16 oz, then it is rejected.
Then the extremes are:
16oz - 0.3oz = 15.7oz (this mas counts as a rejected one)
So we have that the mass of the bag must be larger than 15.7oz
M > 15.7oz
Now, the other extreme is:
16oz +0.3oz = 16.3oz (again, this a rejected mass)
Then the mass of the bag must be smaller than 16.3oz
M < 16.3oz
Then the range of the accepted mass of the bags is:
15.7oz < M < 16.3oz

In an effort to prepare for retirement, Zeus decided to sell off some of his powers to Poseidon. Each box of powers contained 4 specific powers. Each box cost Zeus $250. If Zeus wanted to make a profit $900 per box, how much would have to charge Poseidon for each power?
Answers
Answer:
$287.50Step-by-step explanation:
From the problem statement the cost price per box is
$250.
And the box contains 4 specific powers, since Zeus plans to make $900 per box which contains 4 powers
we need to find the selling price
profit= selling price-cost price
let the selling price be x
900=x- 250
x=900+250
x= 1150
Selling price = $1150
Hence the unit cost of a specific power in a box that will see a profit of $900 per box is 1150/4= $287.50

Answer:
see the attachment for a graph
Step-by-step explanation:
We can't tell what your instructions are. Many graphing tools will let you click on the locations of the points, then draw a line through them. The attached image is from one such tool.
__
If you want to plot this by hand, you do it essentially the same way: plot the two points and draw a line through them.
If you want to write an equation for the line, you can start with the 2-point form:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (5 -(-3))/(2 -(-4))(x -(-4)) -3
y = 8/6(x +4) -3
y = 4/3x +16/3 -9/3
y = 4/3x +7/3
__
Personally, about the only thing useful I find in this equation is that it tells you the slope is 4/3. You can determine the same thing by counting grid squares between the plotted points on the graph. The line goes up 8 for each 6 to the right, so slope = rise/run = 8/6 = 4/3.

the sum of 2 numbers is 16, and the sum of their squares is 146. find the 2 numbers
Answers
Step-by-step explanation:
x + y = 16 (*)
x^2 + y^2 = 146 (**)
(*) <=> x= 16-y
substitute x = 16 - y
(**) <=> (16-y)^2 + y^2 = 146
<=> y^2 - 2.16.y + 16^2 + y^2 = 146
<=> 2y^2 - 32y + 110 = 0
<=> y^2 - 16y + 55 = 0
<=> (y-11)(y-5) = 0
<=> y=11 or y= 5
For y = 11, we have x= 16-11=5
For y=5, we have x= 16-5=11
Answer: (x,y) = (11,5) ; (5,11)
