There are 12 total letters, of which 3 are A's.

This means you have a $\dfrac3{12}=\dfrac14=0.25=25\%$ probability of randomly selecting an A.

If a person puts 1 cent in a piggy bank on the first day, 2 cents on the second day, 3 cents on the third day, and so forth, how

cluponka [151]

This is an arithmetic sequence with the common difference being 1

and if u have 1 cent on day 1 and 2 cents on day 2....then on day 40, u would have 40 cents....but we need the sum of all the days..

the sum of an arithmetic sequence can be found using the formula :
sn = n(a1 + an) / 2
n = number of terms = 40
a1 = first term = 1
an = last term = 40

now we sub
s(40) = 40(1 + 40) / 2
s(40) = 40(41)/2
s(40) = 1640/2
s(40) = 820.....820 cents = $ 8.20 <== the sum

The data below shows the minimum wage requirement

Answer:

We select the option c.

$y=0.114x+0.691$

Step-by-step explanation:

<u>Best Fit Regression Model</u>

Scientists often wonder if there is a relationship between the variables under study. It's a vital matter in modern times where artificial intelligence technology is struggling to find answers where traditional approaches hadn't before.

The most-used tool to find relations between variables is the regression model and its best fit lines to try to find an expression who relates variable x (years from 1960) and variable y (minimum wage requirement) as of our case.

The data was entered into a digital spreadsheet and an automatic function was applied to find the best-fit model.

The automated tool's output was this equation:

$y=0.11363x+0.6906$

That can be rounded to three decimals

$y=0.114x+0.691$

We select the option c.

If you take out a loan for $4,000 and you will owe $4,920 after 2 years, what is the rate of simple interest? Express your answe

11111nata11111 [884]

Answer:

11.5

Step-by-step explanation:

Simple interest formula:

$I=P\cdot r\cdot t,$

where

I = interest

P = principal

r = rate

t = time

In your case,

P = $4,000

I = $4,920 - $4,000 = $920

t = 2 years

So,

$920=4,000\cdot r\cdot 2\\ \\r=\dfrac{920}{2\cdot 4,000}=0.115$

The rate as decimal is 0.115 that is 11.5% as percent
