How many black keys would you expect to find on a keyboard with 72 keys in all? Show your work.

Black_prince [1.1K]

Answer:

50 black keys

Step-by-step explanation:

for every set of 7 white keys there are 5 black keys

72/7 = 10

so there is a total of 10 full sets of keys

then you have 2 white keys remaining but that doesn't matter because they will just be on the dies and already have a black key next

so this means that you only have to calculate the number of 10 sets of black keys and thats 5 x 10.

hope this helps : )

Drag each situation to show whether it can be modeled using a linear or an exponential function. If the situation cannot be mode

lawyer [7]

Answer:

Step-by-step explanation:

A). An investment account earns 2.8% simple interest.

Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.

B). The price of a stock varies by 2.8% each week.

Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.

Therefore, the answer is NEITHER.

C). An investment account earns 2.8% compound interest, compounded monthly.

Formula to get the value of the final amount in the account is,

Final value = Initial value × $(1+\frac{.028}{100})^t$

Here 't' = Duration of investment

It's an EXPONENTIAL FUNCTION.

I NEED HELP ASAP ILL GIVE BRAINLIEST AND 30 points

The question you are asking is not that really hard. In fact it is really easy.

I will give you my examples for some question.

1. (example) The probability of the two heads shown will be more than the two tails shown\

2. Since I hit 17 / 100 (17%) for the two heads and I hit 11 / 100 (11%) for the two tails, then my (example) theory was correct since I stated that there will be more probability showing two heads than on two tails.

Basically at questions 3 & 4 (and also 5 & 6), it is the same as questions 1 & 2.

In question 1, 3, and 5, you need to state what YOU think will happen before doing the 100 coin flip.

Then in question 2, 4, and 6, you need to sate IF YOUR THEORY WAS CORRECT OR WRONG using the results you have. It does not matter if you are wrong.

I will give you my example for 1 and 2 question.

1. (example) The probability of the two heads shown will be more than the two tails shown

2. Since I hit 17 / 100 (17%) for the two heads and I hit 11 / 100 (11%) for the two tails, then my (example) theory was correct since I stated that there will be more probability showing two heads than on two tails.

Basically at questions 3 & 4 (and also 5 & 6), it is the same as questions 1 & 2.

For question number 7, the answer is because my theory is just a guess before the outcome.

You can vote how good my answer is, I just hoped I helped you clarify your misunderstandings.
