Answer:
1st time: 50% chance or 8/16 chance
2nd time: 46% chance or 7/15
I can try again if its wrong
Answer:
7/30
Step-by-step explanation:
8/16 that she picks a red cube.
7/15 that she picks another red cube after keeping the first red cube.
multiply 8/16 (1/2) times 7/15 to get 7/30 as your final answer
Here are some values of sequence Q. Write a recursive definition for the sequence.
n Q(n)
1 3
3 8
7 18
Answer: Q(n) = Q(n - 1) + 2.5
Step-by-step explanation:
We have 3 values of the sequence Q(n)
These values are:
Q(1) = 3
Q(3) = 8
Q(7) = 18
I would think that this is a geometric sequence.
Remember that the equation for the n-th term of a geometric sequence is:
A(n) = A(1)*r^(n-1)
where r is a constant, and A(1) is the first term of the sequence.
If we rewrite the terms that we know of Q(n) in this way we get:
Q(3) = Q(1)*r^(3 - 1) = 3*r^2 = 8
Q(7) = Q(1)*r^(7 - 1) = 3*r^6 = 18
Then we have two equations:
3*r^2 = 8
3*r^6 = 18
We should see if r is the same for both equations:
in the first one we get:
r^2 = 8/3
r = (8/3)^(1/2) = 1.63
and in the other equation we get:
r^6 = 18/3
r = (18/3)^(1/6) = 1.34
Then this is not a geometric sequence.
Now let's see if this is an arithmetic sequence.
The n-th term of an arithmetic sequence is written as:
A(n) = A(1) + (n - 1)*d
where d is a constant.
If we write the terms of Q(n) that we know in this way we get:
Q(3) = Q(1) + (3 - 1)*d = 3 + 2*d = 8
Q(7) = Q(1) + (7 - 1)*d = 3 + 6*d = 18
We need to see if d is the same value for both equations.
in the first one we get:
3 + 2*d = 8
2*d = 8 - 3 = 5
d = 5/2 = 2.5
In the second equation we get:
3 + 6*d = 18
6*d = 18 - 3 = 15
d = 15/6 = 2.5
d is the same for both terms, then this is an arithmetic sequence.
An arithmetic sequence is a sequence where the difference between any two consecutive terms is always the same value (d)
Then the recursive relation is written as:
A(n) = A(n - 1) + d
Then the recursive relation for Q is:
Q(n) = Q(n - 1) + 2.5

The old bag of marbles contains 4 blue and 3 red marbles. If you were to double the number of red and blue marbles to create a NEW bag, would the chance of pulling out a blue marble be the same as pulling a blue marble from the old bag? (this is for math class by the way-)
Answer:
The chance will be the same (4/7)
Step-by-step explanation:
Old bag
p(blue)=4/7
New bag
p(blue)=8/14=4/7
The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.

25 apples to 10 oranges. What is the rate of the fruit
Answer:
The rate of the fruit is 5 apples to 2 oranges.
Step-by-step explanation:
The rate of the fruit is the ratio of apples to oranges. That is, the number of apples divided by the number of oranges into its simplest fraction form:
[tex]x = \frac{25\,apples}{10\,oranges}[/tex]
[tex]x = \frac{5\,apples}{2\,oranges}[/tex]
The rate of the fruit is 5 apples to 2 oranges.

What is the value of t in the equation?
-3t – 4 (t – 5) = 48
Step-by-step explanation:
-3t-4t+20=48
-7t=28
t=-4
Answer:
t = -4
Step-by-step explanation:
-3t – 4 (t – 5) = 48
Distribute
-3t -4t +20 = 48
Combine like terms
-7t +20 = 48
Subtract 20 from each side
-7t +20-20 = 48-20
-7t = 28
Divide by -7
-7t/-7 = 28/-7
t = -4

A group of people attempt to bake the largest vegan cake the used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. How many kilograms of cocoa powder and dates do they use?
Answer: 187 kilogram
Step-by-step explanation:
Let the kilogram of dates be represented by x.
Since they used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. The dates will be:
= 1/10 × x = 17
0.1x = 17
x = 17/0.1
x = 170 kilogram
Date = 170 kilogram.
Cocoa powder = 17 kilogram
The total kilogram of date and cocoa powder used will be:
= 170 + 17
= 187 kilogram
