The probability that Sharon randomly selects two apples from the basket of fruits, given that there are 5 apples and 3 pears, can be expressed as a fraction.
To find the probability, we need to consider the total number of possible outcomes and the number of favorable outcomes.
The total number of possible outcomes is the number of ways Sharon can select any two fruits from the basket, which can be calculated using combinations. In this case, there are 8 fruits in total, so the total number of possible outcomes is C(8, 2) = 28.
The number of favorable outcomes is the number of ways Sharon can select two apples from the five available in the basket, which is C(5, 2) = 10.
Therefore, the probability that both fruits Sharon selects are apples is 10/28, which can be simplified to 5/14.

Quick algebra 1 assignment for 50 points!
Experts and Geniuses please help asap, TYSM!
Oh by the way this is just a section of the real assignment, the assignment calls for you to make an app that people can play to learn inverse variation & direct variation and stuff.
Hope that helps solve this! :)
Step-by-step explanation:
Direct variation is essentially a linear equation, where there is a constant rate. Direct variation can be applied to many things, and we can use it to represent how much money someone has in their bank account after "x" weeks if they're depositing a constant amount of money each week.
So a practical example would be: If someone just opened a bank account and deposits $50 every week, how many weeks will it take for them to have $400 in their account.
So the slope is given in the question, it's $50, since their depositing that constant amount each week. So this gives us the equation: [tex]y=50x[/tex] where x represents the amount of weeks. The y represents the amount of money they have, and since we want to find when this equals 400, we set the y=400, and then solve for x. This gives us the equation: [tex]400=50x[/tex]. Dividing both sides by 50 you get: [tex]8=x[/tex]. So it'll take 8 weeks to have $400 dollars, if you deposit 50 dollars each week.

Find the circumference and the area of a circle with diameter equal to 8.6 inches. Use 3.14 for pie.
The circumference and area of the circle are 27. 0 inches and 58. 0 inches square respectively.
How to calculate the circumferenceThe formula for circumference of a circle is given as;
Circumference = 2 π r
We have diameter = 8. 6 inches
Radius = diameter/ 2
Radius = 8.6/2 = 4. 3 inches
Circumference = 2 × 3. 14 × 4. 3 = 27. 0 Inches
The formula for area of a circle = π r ^2
Area = 3. 14 × 4. 3 × 4. 3
Area = 58. 0 Inches square
Thus, the circumference and area of the circle are 27. 0 inches and 58. 0 inches square respectively.

Find the x - and y -intercepts of the graph of the linear equation 2 x plus 3 y is equal to 2x+3y=12
Answer:
x-intercept is 6 [(6, 0) is the point]
y-intercept is 4 [(0, 4) is the point]
Step-by-step explanation:
To find the x-intercept, we can set y equal to 0 and solve for x. This works because the x-intercept is the point of the graph where the line crosses the x-axis (meaning y is equal to 0 at this point. So, if we set y=0 and solve, we get this:
[tex]2x+3(0)=12\\2x=12\\x=6[/tex]
So, the x-intercept is 6; if it is written as a point, it is (6, 0) since y is 0
To find the y-intercept, we can set x equal to 0 and solve for y. This works the same way - x is equal to 0 at the point where the line crosses the y-axis. If we set x=0 and solve, we get this:
[tex]2(0)+3y=12\\3y=12\\y=4[/tex]
So, the y-intercept is 4; if it is written as a point, it is (0, 4) since x is 0

Kryton -85 is a radioisotope of krypton that has a half-life of about 10.75years. This isotope is produced by the nuclear fission of uranium and plutonium in nuclear weapons and in nuclear reactors, as well as cosmic rays. An important goal of the Limited Nuclear Test Ban Treaty of 1963 was to eliminate the release of such radioisotopes into the atmosphere. At present, the activity of Krypton -85 in the atmosphere is about 135 mCi.

How to use the distributive property to multiply two variables together
Distributive property states that A × (B + C) = AB + AC. are always equal.
According to the statement
we have to explain the distributive property over multiplication.
Distributive property is the multiplication property.
According to this property, it generalizes the Distributive Law and it tells us that the an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.
It means that From distributive property
A × (B + C) = AB + AC.
These are always equal with each other.
Now we will explain with an example,
Let A = 2, B = 3 and C = 4
Then
2 × (3 + 4) = 2(3) + 2(4).
2 × (7) = 2(3) + 2(4).
14 = 6 + 8.
14 = 14.

park. They have no more than $420 to spend on
parking and admission. Parking is $8.75, and
tickets cost $25.75 per person, including tax.
Which inequality can be used to determine x, the
maximum number of people who can go to the
amusement park?
Answer:
The maximum amount of people that can go to the amusement park is 15.
Step-by-step explanation:
First you create an equation to represent the question
8.75+25.75x≤420
You put the less than or equal to sign because 420 is the maximum amount of money.
Now you just solve the equation.
25.75x≤420-8.75
25.75x≤411.25
x≤411.25/25.75
x≤15.9708738
Then you have to round down because you cant have .9 of a person.
So x≤15
Then, Check your solution
8.75+(25.75 x 15)≤420
8.75+386.25≤420
395≤420
That is true. But to make sure that is the maximum add another 25.75
395+25.75≤420
420.75≤420
This is equation is false so, our answer is correct.
The maximum amount of people that can go to the amusement park is 15.
