Answer:

There is 45 ml HCI in the bottle.

Step-by-step explanation:

Given,

Total volume of the bottle = 60 ml,

Also, the bottle is marked 75% HCI,

Hence, the volume of the HCl in the bottle

= 75% of the volume of the bottle

= 75% of 60

$=\frac{75\times 60}{100}$

$=\frac{4500}{100}$

$= 45 \text{ ml}$

If a person starts investing $100 per month starting at age 21, and that money earns a 5% return every year, how much will this

aalyn [17]

The formula for calculating compound interest with yearly contributions is:

Balance = X*(1 + Y)^n + Z((1 + Y)^(n + 1) - (1 + Y)/Y)

where the balance is the money earned after n years invested

Y is the interest rate as a fraction

Z is the yearly contribution

X is the starting investment

Therefore the calculation for this example is:

Balance = 1200*(1 + 0.05)^48 + 1200((1.05)^49 - (1.05)/05)

= $249,393.5

413 divided by 14 How do you it?

guajiro [1.7K]

You can either do this on the calculator, or in your head. As its a larger number, it is worth doing it on the calculator.
413/14= 29.5
The alternative method is to list all of the tens multiples, and the smaller multiples when you're getting close to the answer, and this will be able to help you.
14x10= 140
14x20=280
14x30= 420 (which is slightly too big)
14x29= 406 (slightly too small)
14x29.5= 413

Hope this helps :)

Which of the following is NOT a possible value for the correlation coefficient? 1) negative 0.9 2) zero 3) positive 0.15 4) posi

AnnyKZ [126]

Answer:

4) positive 1.05

Step-by-step explanation:

Correlation:-

Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together.

Examples:i) The yield of a crop varies with the amount of rainfall

ii) The price of a commodity increases with the reduction in its supply and so on.

That is when the changes in one variable are associated or followed by changes in the other, is called correlation

positive correlation:- If an increase (or decrease ) in the values of one variable corresponds to an increase(or decrease ) in the other, then correlation is said to be positive.

negative correlation:- If an increase (or decrease ) in the values of one variable corresponds to an decrease(or increase ) in the other, then correlation is said to be negative.

no correlation:-

If there is no relationship indicated between the variables,they are said to be independent or uncorrelated.

uses of correlation:-it is used in presenting the average relationship between any two variables through a single value of co-efficient of correlation. correlation is a statistical technique that can show whether and how strongly pairs of variables are related.

The range of correlation is $-1\leq r\leq 1$

r=-1 is the negative correlation

r=1 is the positive correlation

so the answer is not a possible value for the correlation coefficient is positive 1.05.
