Answer:
B56 or D65 or B65 or D56
Step-by-step explanation:
a. 36, 26letters + 10 numbers
b. 1/2
c. 1/4
The size of the sample space is 8.
The probability that it has a letter that immediately follows an odd number is 1/2.
There is no probability that D is in the code but not in the first position.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The size of the sample space is the number of ways to choose one letter and two numbers, without repetition.
We can choose the letter in 4 ways, the first number in 2 ways, and the second number in 1 way (since we can't repeat a number), giving a total of 4 x 2 x 1 = 8 possible codes.
Let's list all the possible codes: 5A6, 5B6, 5C6, 5D6, 56A, 56B, 56C, 56D
The probability that a code has a letter that immediately follows an odd number:
We need to count the number of codes that have a letter following an odd number.
From the list above, we see that the codes 5B6, 5D6, 56B, and 56D have a letter following an odd number.
Therefore, there are four favorable outcomes out of eight possible outcomes.
So the probability is 4/8 = 1/2.
The Probability that D is in the code but not in the first position:
D can be in the second or third position.
If D is in the second position, there are 3 ways to choose the first digit (since we can't use D, and we can't repeat the first digit), and 1 way to choose the third digit, giving a total of 3 * 1 = 3 codes.
If D is in the third position, there are 3 ways to choose the first digit and 2 ways to choose the second digit (since we can't repeat any digit), giving a total of 3 x 2 = 6 codes.
So there are 3 + 6 = 9 favorable outcomes out of 8 possible outcomes (since there are 8 possible codes in total).
Therefore, the probability is 9/8, which is greater than 1.
This is not possible, so the answer is that there is no probability that D is in the code but not in the first position.
Thus,
The size of the sample space is 8.
The probability that it has a letter that immediately follows an odd number is 1/2.
There is no probability that D is in the code but not in the first position.

What is the length of the missing leg? If necessary, round to the nearest tenth
Answer: 48 yards
Step-by-step explanation:
Answer: 48 yd
Step-by-step explanation:
when trying to find one leg of a triangle given the other two, a^2 +b^2 = c^2 is applicable. A representing the first leg, B representing the second, and C representing the hypotenouse (a and b are interchangeable). So,
formula: a^2 + b^2 = c^2
insert given: 20^2 + b^2 = 52^2
exponents: 400 + b^2 = 2704
subtract: b^2 = 2704 - 400
simplify: b^2 = 2304
square root of both sides: b = [tex]\sqrt{2304}[/tex]

A cereal box in the shape of a rectangular prism has a volume of 18x^3 - 3x^2 - 6x. What are three possible linear expressions for the dimensions of the cereal box?
From factoring, the volume of a rectangular prism can be written as:
3x * (2x+1) * (3x-2).
FactoringIn math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
The question gives: 18x³-3x²-6x. You can see that, initially, 3x is a common term. Therefore, you can write: 3x * (6x²-x-6) . Nonetheless, the question also asks 3 linear expressions, here only you have one (3x).
Thus, you should factor the expression (6x²-x-6) into two linear expressions: (2x+1)* ( 3x-2).
Thus, the volume of a rectangular prism can be written as:
3x * (2x+1) * (3x-2)

An ice cream factory makes 220 quarts of ice cream in 10 hours. How many quarts could be made in 36 hours? What was that rate per day?
( I will mark brainliest, please answer+explain!)
Answer:
For 36 hours, that would be 792 quarts. The unit rate is 528 quarts per day.
Step-by-step explanation:
If you divide 36 by 10, you get 3.6, and then you multiply that with 220. That gets you 792 quarts for 36 hours. To find out the rate per day, do 24 divided by 10, and then multiply that by 220.

You and your friends go to the diner and order burgers and drinks. Each burger costs $8.00 and one soda costs $2.50. Combined, you and your friends order twice as many burgers as you do sodas, s.
a. Write an algebraic expression that represents the number of hotdogs you and your friends want to buy.
b. Combined, you and your friends can spend no more than a $100 gift card. Write an inequality that represents the number of burgers and sodas you and your friends can buy.
C. Solve your inequality from part b. and state the maximum number of sodas that can be purchased.
The answers to your questions are as we have them below:
a. s ( 2 burgers + 1soda )
b. s ( $16.00 + $2.50) ≤ $100
c. The maximum number of sodas that can be purchased is 5.40 sodas
Algbraic expressionAn algebraic expression is an expression containing integer constants, variables and algebraic operations
Detailed solution of the above is given below:
One Burger costs $8.00
One soda costs $2.50
Combined = s (2burgers + 1soda)
where s is the number of persons ordering.
a. s ( 2 * $8.00 + $2.50 )
s ( $16.00 + $2.50) = s($18.50) assuming that the hotdogs will be the total amount to be spent
b. if the cant spend more than a $100 gift card, the inequality will be
s ( $16.00 + $2.50) ≤ $100
s($18.50) ≤ $100
s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40
Therefore the number of burgers and soda they can buy is
5.40 (2burgers + 1soda) = 10.80 burgers and 5.40sodas
c. s ( $16.00 + $2.50) ≤ $100
s($18.50) ≤ $100
s ≤ [tex]\frac{100}{18.50}[/tex] = 5.40
The maximum number of sodas that can be purchased is 5.40 sodas

The vertex form of the provided equation y = (x 3)2 (x 4)2 is expressed as (x+3.5)²+0.5.
What is the vertex form of parabola?Vertex form of parabola is the equation form of quadratic equation, which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.
The standard equation of the vertex form of parabola is given as,
y=a(x-h)^2+k
Here, (h, k) is the vertex point.
The given equation is
[tex]y = (x +3)^2 +(x+ 4)^2\\y=x^2+9+6x+x^2+16+8x\\y=2x^2+14x+25[/tex]
To convert this equation, into the vertex form, follow the following steps,
[tex]y=2(x^2+7x+12.5)\\y=2((x+3.5)^2-12.25+12.5)\\y=(x+3.5)^2+0.5[/tex]
