There is a deck of 70 flashcards and each card has a different number ranging from 1 to 70. Find the theoretical probability of the event when picking from a deck of flashcards. P(the number is even) P(the number is even)eqauls (Simplify your answer.)
Half the cards are even, 70/2 = 35 even cards.
The probability of picking an even card = 35/70, which reduces to 1/2
The theoretical probability of the event when picking from a deck of flashcards is [tex]\({\frac{35}{70}}\)[/tex].
To find the theoretical probability of picking an even number from a deck of 70 flashcards, we need to calculate the number of favorable outcomes (even numbers) and divide it by the total number of possible outcomes (all numbers from 1 to 70).
The total number of flashcards is 70, so there are 70 possible outcomes.
Since each card has a unique number from 1 to 70, there are 35 even numbers within this range (2, 4, 6, ..., 70). This is because the even numbers are every other number in the sequence from 1 to 70.
Therefore, the number of favorable outcomes (even numbers) is 35.
The probability of picking an even number is the number of favorable outcomes divided by the total number of possible outcomes:
[tex]\[ P(\text{the number is even}) = \frac{\text{Number of even numbers}}{\text{Total number of flashcards}} \] \[ P(\text{the number is even}) = \frac{35}{70} \][/tex]
Therefore, the final answer, as requested, is [tex]\({\frac{35}{70}}\)[/tex].

The price of a certain item is P dollars. The sales tax on the item is 7%. which expression represent the total cost of the item, in dollars, after the tax has been applied?
Answer:
1.07p or p + 0.7p
Step-by-step explanation:
The price of any item plus 7% tax can be found by writing an expression. You can write an expression using a variable p where p is the price. You will pay the 100% the whole price and add on 7% of the price as tax. This means you pay 100 + 7 = 107% of the price p. This is 1.07p. Or you can also write it as p + 0.07p.

Martha has a bidget for groceries etc. She spent 20% of her budget on groceries. If martha spent $42.00 on groceries how much is her budget.
THIS MATH IS CONFUSING ME
Final answer:
Martha's total budget for groceries is calculated using the proportion of the amount spent, which is $42.00 corresponding to 20% of her budget. By cross-multiplying and dividing, we find that her total budget is $210.00.
Explanation:
To figure out Martha's budget for groceries based on the percentage she spent, we can use proportions. If Martha spent $42.00 on groceries, which represents 20% of her budget, we can set up the proportion as follows:
20% (the percentage spent on groceries) / 100% (the total budget) = $42.00 (amount spent on groceries) / B (total budget)
Now, we solve for B using cross-multiplication:
20% * B = 100% * $42.00
0.20 * B = $42.00
B = $42.00 / 0.20
B = $210.00
Hence, Martha's total budget is $210.00.

Which is the missing term? (10x - 4x^2)-(7x+ ? ) = 3x-6x^2
2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.
Answer:
The missing term is -2x²
Step-by-step explanation:
It is given that,
(10x - 4x² ) - (7x + ?) = 3x - 6x²
To find the missing term
Let 'M' be the missing term we can write the above equation,
(10x - 4x² ) - (7x + M) = 3x - 6x²
⇒ 10x - 4x² - 7x + M = 3x - 6x²
⇒ 10x - 7x - 4x² + M = 3x - 6x²
⇒ 3x - 4x² + M = 3x - 6x²
M = -6x² + 4x²
M = -2x²

How do i solve these questions?
In an expression, there are terms, which are a number(s) that are combined by multiplication but separated by addition (if you see subtraction it's just adding the negative version of the number). In this case, there are 5 terms. A term can have a variable or it can be a constant. A constant is just a number. We can combine constants. For example, in this case, we can combine 22 and -8 to get 14. (just adding). If it has a variable, we can only combine two terms if they have the same variable, so 5m and -4m can be combined to get m. We replace the terms we have combined with the combined terms so we have m + 7n + 14.

A yogurt company charges 72 cents for a 6 ounces container of yogurt. How much does it charge for an 8 ounce container?
Answer:
Step-by-step explanation:
If
72 cents ---> 6 ounces
Xcents -----> 8 ounces
then
X = [(72)*(8)] / 6
X = 96 cents
Best regards
The yogurt company charges 12 cents per ounce. Therefore, an 8 ounce container would cost 96 cents.
Explanation:The subject of this question is about cost per ounce for a yogurt container. First, we need to find the cost per ounce. This would be the total cost divided by the number of ounces. In this case, 72 cents for a 6 ounce container gives us 72/6 = 12 cents per ounce. If we then want to find the cost of an 8 ounce container, we can multiply the cost per ounce by the number of ounces. So, 12 cents per ounce times 8 ounces equals 96 cents. Therefore, an 8 ounce container would cost 96 cents.

Tyler simplified the expression
Answer:
"Both powers should be in the denominator with positive exponents"
Step-by-step explanation:
One rule of exponents is [tex]a^b=\frac{1}{a^-b}[/tex]
This means that the exponent changes sign when brought from numerator to denominator, or vice versa.
Looking at 2nd step of Tyler's work, we can see that he successfully used this rule with the exponent of x, but forgot to change the sign of the power of y to 9.
Since both the powers were negative when in the numerator, they should both be positive when taken to denominator. Hence, the correct answer is "Both powers should be in the denominator with positive exponents"

The value of Jeunesse’s retirement account fell by $678.75 over a period of 3 months. What was the average change in value per month?
The average change in value per month is 2
$226.25 .
To find the average change in the value of Jeunesse's retirement account per month, you divide the total fall in value ($678.75) by the number of months (3). This results in an average monthly decrease of $226.25.
Explanation:The problem requires us to compute the average change in Jeunesse's retirement account over a period of three months. The total change is $678.75. To calculate the average change for each month, we need to divide the total change by the number of months. This is also known as finding the average rate of change.
So, to compute it for Jeunesse's retirement account, we have:
Take the total change in the account, which is -$678.75. Divide this by the number of months, which is 3. This results in -$678.75 / 3 = -$226.25

Which of the following points lies on the circle whose center is at the origin and whose radius is 10
Answer:
Step-by-step explanation:
No given points, but you can figure it out from the equation of the circle:
Centered at the origin means that a = b = 0 in
(x-a)^2+(y-b)^2=radius^2
leaving the following:
x^2+y^2=10^2
or x^2+y^2=100
then, from the given points, plug in the coordinates and check to see if it satisfies the equation.
For example, we already know that (10,0) will be on the circle, since it is centered at the origin with radius 10. We can check by plugging into the equation: (10)^2+0^2=100
100=100, so the point lies on the circle.
Side note:
To find which points are within the circle, the equation x^2+y^2<10^2 would have to be satisfied. In this case, (9,0) is one of infinitely many points which satisfies this equation, and therefore is inside the circle.
