The value for the diamonds which would make the game of pick a diamond from a deck of 52 cards fair is 6.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
From a card at random from an ordinary deck of 52 cards is picked.If the card is a diamond, you get some points. There are total 13 diamonds in a deck of cards.
Thus, the probability of picking a diamond from 52 cards is,
[tex]P=\dfrac{13}{52}\\P=\dfrac{1}{4}[/tex]
The probability of not picking a diamond from 52 cards is,
[tex]P'=1-\dfrac{1}{4}\\P'=\dfrac{3}{4}[/tex]
If the picked card is not a diamond, then the 2 points are lost. Let X is the score in the game. If the game is fair then the expected value for this should be 0. Thus,
[tex]0=x\times \dfrac{1}{4}+2\times\dfrac{(-3)}{4}\\x=6[/tex]
Hence, the value for the diamonds which would make the game of pick a diamond from a deck of 52 cards fair is 6.

If you can type 50 words per minute, how many minutes would it take you to type a 500 word essay
==========================================
Work Shown:
A = 50 = number of words typed in 1 minute
B = 1 minute
C = 500 words
D = x minutes (needed to type 500 words)
A/B = C/D
50/1 = 500/x
50*x = 1*500 ... cross multiply
50x = 500
x = 500/50 .... divide both sides by 50
x = 10
You'll need 10 minutes to type 500 words
------------
Alternative approach:
50 words = 1 minute .... given speed
1 word = 1/50 minute ... divide both sides by 50
1 word = 0.02 minute
500 words = 10 minutes .... multiply both sides by 500
As per the given data, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.
If you have a typing speed of 50 words per minute, it means you can accurately type 50 words in one minute. This rate is often considered an average typing speed for proficient typists.
If I can type 50 words per minute, then to determine the number of minutes it would take to type a 500-word essay, we can divide the total number of words by the typing speed:
Time (in minutes) = Total words / Typing speed
Time = 500 words / 50 words per minute
Time = 10 minutes
Therefore, it would take approximately 10 minutes to type a 500-word essay at a typing speed of 50 words per minute.

A. Write the formula for the volume V of a prism where B is the area of the base and h is the height. V= b. Solve the formula for B. B= c. Use the new formula to find the area of the base of the prism. The area of the base of the prism is square inches.
Step-by-step explanation:
The question lacks the required diagram, find the diagram attached.
Volume of the pyramid V = BH where;
B is the base area
H is the height of the prism.
b) To solve for B, we will have to make B the subject of the formula from the equation in a;
From (a);
V = BH
Divide both sides by H
V/H = BH/H
V/H = B
B = V/H
c) Since we are not given the volume and height of the prism, we can as well use the following parameters;
Let us assume Volume of the prism = 175in³ and eight of the prism H = 5in
Substitute this values into the equation derived in (b)
B = 175in³/5in
Hence the area of the base of the prism is square inches is 35in²

Step-by-step explanation:
y= -16 (total amount of meters below ground)
m= -1.5 (slope; meters he descends per minute)
x= 6 (minutes)
b= -7 (starting point)
thus; y= -1.5x-7

Which inequality represents the following statement?
"A number increased by 4 is at most 15."
Answer:
x + 4 ⩽ 15
Step-by-step explanation:
Let
The number = x
At least in inequality is ⩾ (greater than or equal to sign)
At most in inequality is ⩽ ( less than or equal to sign)
A number increased by 4 is at most 15.
x + 4 ⩽ 15
The inequality that represent the statement is x + 4 ⩽ 15
x + 4 ⩽ 15
x ⩽ 15 - 4
x ⩽ 11

Answer:
3
Step-by-step explanation: 8 can go into 24 perfectly but not 15 and 5 can go into 15 perfectly but not 24 but 24/3 is 8 and 15/3 is 5
You might say two could do the same thing which is true but we are talking about the GCF, they are asking for the greatest common factor so that's why the answer is 3
Answer:
3
basically, 8 can go into 24 exactly but 15 and 5 can not go into 15 perfectly neither can 24. 24/3 is 8 and 15/3 is 5
You might say two could do the same thing which is true but we are talking about the GCF, they are asking for the greatest common factor so that's why the answer is 3 :D

A baseball team is having an end of the year party and the coach wants to purchase gloves and baseballs for the team. Gloves are sold in cases of 8 and baseballs are sold in cases of 12. The coach wants to buy the exact same number of gloves as baseballs.What is the least number of gloves and baseballs he would have to purchase to have the same number of each?
Answer: 24 is the least number of gloves and baseball need to purchase .
Step-by-step explanation:
Given: Gloves are sold in cases of 8 and baseballs are sold in cases of 12.
To get the exact same number of gloves as baseballs, the least number of gloves and baseball need to purchase = L.C. M. (8,12)
[L.C.M.= Least common multiple]
Since 8 = 2 x 2 x2
12 = 2 x 2 x 3
So, L.C. M. (8,12) = 2 x 2 x 2x 3 = 24
Hence, the least number of gloves and baseball need to purchase = 24
