Ben wants to buy a new collar for each of his 5 dogs. The collars come in a choice of 9 different colors. Step 1 of 2 : How many selections of collars for the 5 dogs are possible if repetitions of colors are allowed
Answers
Answer:
59049 ways
Step-by-step explanation:
Given
[tex]Colors = 9[/tex]
[tex]Dogs = 5[/tex]
Required
Determine number of selection (repetition is allowed)
The number of collars is not given.
So, we'll assume that there are enough collars to go round.
If no repetition is allowed, each of the 5 dogs have 9 colours to select from.
i.e.
[tex]Dog\ 1 = 9[/tex]
[tex]Dog\ 2 = 9[/tex]
[tex]Dog\ 3 = 9[/tex]
[tex]Dog\ 4 = 9[/tex]
[tex]Dog\ 5 = 9[/tex]
So, the number of selection is:
[tex]Selection = 9 * 9 * 9 * 9 * 9[/tex]
[tex]Selection = 59049[/tex]
Olivia and Cody both have spinners with the color purple. Olivia determines that the probability of spinning purple on her spinner is 4 out of 12. Cody determines that the probability of spinning purple on his spinner is 3 out of 10. Which of the following statements is true?
Answers
So the answer would be B
The true statements:
A) Olivia's spinner has the highest probability of spinning purple.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
Olivia and Cody both have spinners with the color purple.
Olivia determines that the probability of spinning purple on her spinner is 4 out of 12.
That means, 4/12 = 0.33
Cody determines that the probability of spinning purple on his spinner is 3 out of 10.
That means, 4/10 = 0.3
0.33 > 0.3
Therefore, Olivia's spinner has the highest probability of spinning purple.

Answer and Step-by-step explanation:
The square root of 16 times x to the power of 6 times y to the power of 10 is the same as:
[tex]\sqrt{16x^{6} y^{10} } = \sqrt{16} * \sqrt{x^{6} } * \sqrt{y^{10} }[/tex]
The square root of 16 is 4.
The square root of x to the power of 6 is x to the power of 3.
The square root of y to the power of 10 is x to the power of 5.
So, the answer is:

Which of the following did you include in your answer? Yes, the graph has been dilated. Using the standard form of the equation, substitute in the values: h = –2, k = 3, x = –1, and y = 0. Solve the equation to get a = –3. Graphically, the parent function follows the pattern of right 1, up 1. Moving 1 unit to the right from the vertex, you can move down 3 units to get to the point (–1, 0), so it has been horizontally compressed.

Carmen deposits $4000 into an account that pays simple interest at a rate of 3% per year. How much interest will she be paid in the first 3 years?
Answers
Answer:
$360
Step-by-step explanation:
I = Prt
I = 4000 * 3 * 3%
I = 12000 * 3% (Convert 9000 and 3% into fractions.)
I =12000/1 * 3/100 (100 and 12000 have a GCF of 100)
I = 120/1 * 3/1 (Disregard the over 1 portion.)
I = 120 * 3 (Multiply 120 by 3 to get 360.)
I = $360
