Answer:
[tex]y^{ \frac{3}{2}}[/tex]
Step-by-step explanation:
From the question posted, you've already initiated the solution but you applied a wrong approach;
Given
[tex]y^{\frac{4}{3}} . y^{\frac{2}{3} - \frac{1}{2}}[/tex]
Required
Simplify; using power property
Power property states that;
[tex]a^m.a^n = a^{m+n}[/tex]
[tex]a^m/a^n = a^{m-n}[/tex]
By comparison; we have to apply the first property;
This is shown below;
[tex]y^{\frac{4}{3}+\frac{2}{3} - \frac{1}{2}}[/tex]
Add fraction of the same numerator
[tex]y^{\frac{4+2}{3} - \frac{1}{2}}[/tex]
[tex]y^{\frac{6}{3} - \frac{1}{2}}[/tex]
[tex]y^{2 - \frac{1}{2}}[/tex]
Subtract fraction
[tex]y^{ \frac{4-1}{2}}[/tex]
[tex]y^{ \frac{3}{2}}[/tex]
The expression [tex]y^{\frac{4}{3}} . y^{\frac{2}{3} - \frac{1}{2}}[/tex] is equivalent to [tex]y^{ \frac{3}{2}}[/tex]

You want to distribute 7 candies to 4 kids. If every kid must receive at least one candy, in how many ways can you do this?
Answer:
15
Step-by-step explanation:
lets begin to set up this question. i personally find questions like these easiest when i begin to set up ideas to help my brain process it better, for example:
person a
person b
person c
person d
we know that each (person) must receive at least 1 candy. we also know that we have 7 candies. therefore if we want do draw this out :
person a- 1
person b- 1
person c- 1
person d -1
notice that we now have given away 4 of the 7 candies. now we have 3 candies left. we can simply:
person a- 2
person b-2
person c-2
person d- 1
but, keep in mind that there are still many more ways that we can distribute the candies to other kids. the question we are asked is how may ways can we do this. since i have already illustrated the question, you can either learn how to put this into an equation, or experiment how many variations there are. the answer, either way is 15.

A card player selects a playing card from a well-shuffled deck of standard playing cards and sees if the card is a red card or not. He keeps the card, and then makes another selection and sees if the card is a red card or not. He continues this process 10 times and counts the total number of red cards that he selects. Is this a binomial random variable? A. no since the total number of red cards in the deck is unknown at the start of the experiment B. no, since probabilities of drawing red cards do not remain the same from trial to trial C. yes since red cards are successes and he is counting the number of red cards drawn D. yes since a red card is a success and every other card is a failure
Answer:
A
Step-by-step explanation:
there could be no red cards inside
A binomial random variable is no since the total number of red cards in the deck is unknown at the start of the experiment.
We have to determine whether the card player selects a playing card from a well-shuffled deck of standard playing cards and sees if the card is a red card or not.
He keeps the card, and then makes another selection and sees if the card is a red card or not.
What is the probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
He continues this process 10 times and counts the total number of red cards that he selects.
We have to determine if it Is a binomial random variable.
There could be no red cards inside.
Therefore, A binomial random variable is no since the total number of red cards in the deck is unknown at the start of the experiment.

A rectangle is twice as long as it is wide, and has a perimeter of 48 inches, what is the area of the rectangle?
Answer:
128 inches²Step-by-step explanation:
P = 2w + 2l
l = 2w
48 = 2w + 2×2w
48 = 2w + 4w
48 = 6w
w = 48 : 6
w = 8 inches
l = 2w
l = 2×8inches
l = 16 inches
A = w×l
= 8in × 16in

Image attached. Geometry: finding angles
Answer:
28 degrees
Step-by-step explanation:
Because a triangle equals 180, you can subtract 90 and 34 from triangle ABE to leave you with 56 degrees for angle B.
Since CBA is a straigth line with 180 degrees, you can subtract 56 to end up with 124 degrees for angle CBE.
Since line BD bisects angle EBC (splits in half), you can divide the 124 degrees into 62 degrees.
Now that we know angle CBE equals 62 degrees, we can add the 90 degrees and subtract them from the 180 degrees of the triangle.
62+90=152
180-152=28
Consider that 620(1.082)x models the average annual health care costs per person, in dollars, as a function of the number of years since 1950.
Answer:
I guess that you want to calculate the difference between the annual healt care costs in 1950 and today.
The equation is:
C(x) = $620*(1.082)^x
in 1950, we have x = 0 (because is the initial year)
then the cost is:
C(0) = $620*1 = $620.
Now, today, in 2020, we have:
x = 2020 - 1950 = 70
then we have:
C(70) = $620*(1.082)^70 = $154,276.7
So, according to this equation, te difference is:
$154,276.7 - $620 = $153,656.6
Find the equation of the line with slope m= 1/5
that contains the point (-10, 5).
Answer:
y = 1/5x +7
Step-by-step explanation:
The equation of a line is given by
y = mx+b where m is the slope and b is the y intercept
y =1/5 x + b
Substitute the point into the equation
5 = 1/5 (-10) +b
5 = -2 +b
Add 2 to each side
7 = b
y = 1/5x +7
For Restaurant A, the owner wants to advertise a good cleanliness score to his customers. Which measure would make his score seem as good as possible, the mean or the median? median mean
Answer:
median
Step-by-step explanation:
the median would make the score as good as possible, because there could be possible outliers. this really depends on if there are outliers or not. here is an example of what i need:
say you are trying to show your parents your grades:
here are your scores:
38, 88, 90, 91, 93, 95, 100
the median would be 91, which looks better.
the mean would be 85.
even though a majority of your grades are good, the one 38 makes the average go down. therefore, the median is a better advertiser.

Find the inverse of the function.
f(x) = x ^3 + 8
Answer:
The inverse of the function is
[tex] \sqrt[3]{x - 8} [/tex]
Step-by-step explanation:
To find the inverse of the function we equate f(x) to y
That's
f(x) = y
So we have
[tex]y = {x}^{3} + 8[/tex]
Next interchange the terms x becomes y and y becomes x
That's
[tex] x = {y}^{3} + 8[/tex]
Next make y the subject
That's
[tex] {y}^{3} = x - 8 \\ \\ y = \sqrt[3]{x - 8} [/tex]

Answer:
61 wins
Step-by-step explanation:
60 + 1/2*100=110 wins (team A)
110-49=61
Team B needs to win 61 more games to have the same number of wins as team A.
Identify the measure of arc RT. HELP ASAP!
Answer:
The correct option is;
RT = 35°
Step-by-step explanation:
Given the parameters are;
∠SMX = 95°
∠MXS = 45°
arc PW = 80°
arc WY = 35°
From external angle half difference formula, we hve;
Given an external angle, ∠MSX, subtending a far arc x° and a near arc y°, then we have;
∠MSX = 1/2×(x° - y°)
Where:
x° = arc PW + arc WY = 80° + 35° = 115°
y° = arc RT
∠MSX + ∠SMX + ∠MXS = 180° (Sum of interior angles in a triangle)
∠MSX = 180° - (∠SMX + ∠MXS) = 180° - (95° + 45°) = 40°
Therefore;
∠MSX = 1/2×(x° - y°) gives;
40° = 1/2×(115 - y°)
y° = 115° - 2 × 40° = 35°
∴y° = 35° = arc RT.

Explain the procedure (but don't create the graph) for graphing the quadratic function in factored form f(x) = (x - 2)(x + 4) using pencil and paper. Explain the entire process. pleaaassseee help mee.
Answer: You will need to find the x-intercepts and the vertex
Step-by-step explanation: Use the information in the factors and some formulae.
The x- intercepts are the points where the parabola crosses the x-axis. The x-axis is where y = 0
Set each factor equal to 0 and solve:
x-2=0, so x = +2 and x +4 = 0, so x = -4 (you would plot these if creating the graph)
To find the vertex you need the Vertex Formula: x = -b/2a
b is the coefficient of the x term in the middle of the quadratic equation; you can just do the O and I parts of FOIL to get b: -2x + 4x = 2x You know a = 1 because x² will have the implied (missing)(1).
Put the numbers in the Formula: x = -b/2a x = -(2)/2(1) -2/2 = -1
-1 is the "x-value" of the vertex.
The y value is the 'c' in the quadratic formula. You get that from the L part of FOIL -2 × 4 = -8 .
So, your coordinates for the vertex: ( -1, -8 )
If you were creating a graph, you would plot that point, then draw the parabola starting there and through the x-intercepts.
