Answer:
Step-by-step explanation:
distance = rate [tex]*[/tex] time
1 (mile) = rate [tex]*[/tex] 0.5 (hours)

rate = 2 mph...
That however is not answer choice. I'm guessing the number in front of the mile didn't copy over. You can use the same method I did, but just plugging in the actual number instead of 1.

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.

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]

Answer: 92° or 1.6057 radians
Step-by-step explanation:
the 4 angles created by the intersecting lines SU and RT have to equal 360°
<v = 88° because of vertical angles so
88° • 2 = 176°
360° - 176° = 184°
184°/ 2 = 92°
92°+92°+88°+88° = 360°
then, that makes 92° the central angle of arc RU and the central angle degrees is always equal to the arc it subtends

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)

Approaching the left limit, we can see that the graph heads towards negative infinity.
Approaching the right limit, we can see that the graph also heads towards negative infinity.
