One card is drawn at random from a deck of 52 cards. The first card is not replaced, and a second card is drawn. (Enter your probabilities as fractions.)
(a) Find the probability that both cards are diamonds.
Answer:
Step-by-step explanation:
In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).
Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 7.
With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).
Our denominator here is 52 - the number of cards from which we can pull 1.
Our numerator is both all the diamonds, 13 cards, and all the sevens, 4 cards, but we need to subtract 1 to account for the double counting of the 7 of diamonds.
In all we get:

Find the volume of the sphere. **30 points**
Either enter an exact answer in terms of pi or with 3.14
Radius=8
Answer:
The volume of the sphere is 2,143.57
Step-by-step explanation:
The formula for finding the volume of the sphere is
V = [tex]\frac{4}{3}[/tex]π[tex]r^{3}[/tex]
"r" represents the radius of the sphere. So put the value of it in the formula.
V = ([tex]\frac{4}{3}[/tex])(3.14)([tex]8^{3}[/tex])
V = ([tex]\frac{4}{3}[/tex])(3.14)(512)
Multiply all of them and you will get:
2143.57333333 or 2,143.57 which is the volume of the sphere
Kara has five exam scores of 93, 67, 82, 71, and 94 in her biology class. What score does she need on the final exam to have a mean grade of 80?
Round your answer to two decimal places, if necessary. (All exams have a maximum of 100 points.)
Answer:
She needs at least 73%
Step-by-step explanation:
1. add all of the numbers up and d the quantity to find
93+67+82+71+94/5
=407/5
=81.
2. try diffrent numbers
407+73/6
=480/6
=80
She needs at least 73%
Answer:
A score of 73
Step-by-step explanation:
Five exam scores + the final exam = mean (average) of 80.
First find the total points that you need to make an 80 average 80 × 6 = 480 points.
The five exam scores + x score = 480 points.
93 + 67 + 82 + 71 + 94 + x = 480
407 + x = 480
x = 480 - 407
x = 73

GIVING 100 POINTS AND BRAINLIEST IF CORRECT! You recently upgraded your experience by buying an Controller for $74.99 and an Game Pass Subscription for $14.99 per month.
Answer:
Part A: It's linear because it increases at a constant rate of 14.99 dollars per month
Part B: C = 14.99M + 74.99 (y = 14.99x + 74.99)
Step-by-step explanation:
Part A: Every month, you have to pay the same amount.
1 month = 14.99
2 months = 14.99 + 14.99
3 months = 14.99 + 14.99 + 14.99
So, it's linear.
Part B: We have to use the formula y = mx + b, or slope-intercept form, to represent the total cost per month.
m = slope, b = y-intercept (initial value)
Let's have the total cost be represented as C
Let's also have the subscription per month be represented as M
So, C would = 74.99, because we only need to pay for a controller once
But we also our subsription per month, M, as 14.99.
So our final answer would be C = 14.99M + 74.99, or y = 14.99M + 74.99 if you can't make your own variables

assume that y varies directly as x. if y=7 when x=4, find y when x=12
Which of the following equations is an example of inverse variation between
the variables x and y?
A. y = 12x
B. y =х
12
C. y= x + 12
D. y = 12
х
Answer:
The correct answer is option D
Step-by-step explanation:option A : y = x/12 ⇒ x = 12y (wrong option)
option B : y = 12/x ⇒ y * x = 12 (wrong option) and c will be equal 12
option C : y = x + 12 ⇒ not similar to the general form (wrong option)
option D : y = 12/x (corect option)( I meant to switch it around)
The general form of inverse variation between the variables x and y is as following:
where c is constant
So, the correct option is D
