A Nashville-area radio station plays songs from a specific, fixed set of artists. The station has no DJ; instead, a computer randomly selects which songs to play. The songs themselves are picked randomly, and the same song may be played many times in a row. In the set of songs, 45% are sung by a female singer, 45% are sung by a male singer, and 10% are instrumental with no vocals. What is the probability that a particular set of 3 songs contains exactly 2 female singers and 1 male singer? (Hint: Be aware that there are multiple ways to achieve this pattern of songs.)

What is the correlation coefficient of y=0.48x+75.2

Answers

a correlation coefficient shows how linear a set of data is, so for any points that comply with the given equation, the correlation coefficient will be one, that is, the correlation is completely linear, because the given equation is alinear one, there is a linear correlation of x and y. Indeed, the equation is a line equation in general form.

A horse that weighs 1 1/4 tons is carrying a 110 pound person, a 15 ounce water bottle, and a 16 1/2 pound basket what is the weight of the horse, rider, and items in total?

Answers

Answer:

2635.875pounds

Step-by-step explanation:

Converting all the units to pounds for unit consistency. Let's convert

1 1/4tons horse weight and 15ounce water bottle to pounds.

According to the conversion;

1 ton = 2000pounds

1 1/4 tons = (2000×5/4)pounds = 2500pounds

Similarly for the conversion of ounce to pounds;

1 ounce = 0.625pound

15 ounces of water bottle = (0.625×15)pounds

= 9.375pounds

The total weight of the horse, rider, and items in total will give;

2500pounds horse + 110pounds person + 9.375pounds water bottle + 16.5pounds basket

= 2635.875pounds

Solve for
a. 7a-2b = 5a+b

Answers

Answer: The required value of a is $(3)/(2)b.$

Step-by-step explanation: We are given to solve the following equation for variable a :

$7a-2b=5a+b~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To solve the above equation for a, we need to take terms involving a on one side of equality that that involving b on the other side.

So, from equation (i), we get

$7a-2b=5a+b\n\n\Rightarrow 7a-5a=b+2b\n\n\Rightarrow 2a=3b\n\n\Rightarrow a=(3)/(2)b.$

Thus, the required value of a is $(3)/(2)b.$

7a-2b = 5a + b
2a=3b
a = 3b/2

The amount of money left on a loan that Kira owes her grandmothers is represented by the function k(t)=280(.88)^t where k(t) represents the amount of money left on a the loan and t represents the time, in years. Find r, the percent change and explain what it represents.

Answers

Given:
k(t) = 280(0.88)^t

t = 1 ; t = 2 ; t = 3
k(1) = 280(0.88)¹ = 280(0.88) = 246.40
k(2) = 280(0.88)² = 280(0.7744) = 216.83
k(3) = 280(0.88)³ = 280(0.681472) = 190.81

280 - 246.40 = 33.60 ⇒ 33.60/280 = 0.12
246.40 - 216.83 = 29.57 ⇒ 29.57/246.40 = 0.12
216.83 - 190.81 = 26.20 ⇒ 26.20/216.83 = 0.12

The rate is 0.12 or 12%

A carton of paper is priced at $27.00 now. If the papergoes on sale for 25% off the current price, what will be the sale price of the carton?

Answers

If a pack of paper costs $27.00 right now. If the paper is discounted by 25% from its regular price, the carton will be sold for $6.75.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Given that a carton of paper costs $27.00 right now, If the price of the paper is discounted by 25%,

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

The sale price of the carton is,

sale price = 25% of the current price

sale price =(25/100)× $27.00

sale price = $6.75

Thus, if a pack of paper costs $27.00 right now. If the paper is discounted by 25% from its regular price, the carton will be sold for $6.75.
