Mathematics

Answer:

7 hours/week

Step-by-step explanation:

A "unit rate" is found by dividing one quantity by the other so that the denominator of the result is 1 (a unit). Often, we want the units of the independent variable in the denominator. Sometimes, we don't know what that is, because it depends on the intended use of the rate.

(14 h)/(2 wk) = 7 h/wk

When numerator and denominator have the same units, the result is a pure number (one with no units). If that number is a fraction, sometimes it is expressed as a percentage; other times, it is left as a fraction or written as a ratio with a colon, such as 1 : 35.

Here, both units are time, so the "unit rate" could be expressed as a fraction. We know there are 168 hours in a week, so this rate could be ...

(14 hours)/(2·168 hours) = 1/24 . . . . . with no units

Answer:

min: 3

Q1: 6

median: 12

Q3: 14.5

max: 17

Step-by-step explanation:

Put values in order of least to greatest value. Leftmost number is the minimum; rightmost number is the maximum. Middle number is the median (cross out values, alternating crossing out least and greatest values until 1 value is left). Find the median of the values to the left and right of the median; those are Q1 and Q3 respectively.

On a number line what is the distance between -3/2 and 6?

sesenic [268]

Answer:

7.5 units

Step-by-step explanation:

The distance is always positive and is same as the absolute value of subtraction of the two numbers on the line.

<u>This can be shown as:</u>

|-3/2 - 6| =
|-1.5 - 6| =
|-7.5| =
7.5

| 6 - (-3/2)| =
|6 + 1.5| =
|7.5| =
7.5

How much must be deposited today into the following account in order to have $35,000 in 7 years for a down payment on a house?

Rom4ik [11]

Answer:

The amount that must be deposited is $ 19973.87.

Step-by-step explanation:

We have a relation between future value present value as:

F= P $(1 +\frac{r}{n} )^{nt}$

F=future value

P=present value

r=rate (as a decimal)

n=number of compounding periods per year

t=number of years

Now,

assume rate as 8%

35000= P $(1+\frac{0.08}{12} )^{12*7}$

or, 35000= P × $1.0067^{84}$

or, P = $\frac{35000}{1.7522}$

or, P = $ 19973.87

So you must deposit $ 19973.87 today.

You select a card at random from the cards that make up the word “replacement”. Without replacing the card, you choose a second

natta225 [31]

To find the total probability, we first need to solve for the probability of the individual events.

Event 1:
P(consonant)=7/11
We know this to be true because out of the 11 total possibilities for the event, 7 of them are consonants.
R E P L A C E M E N T

Event 2
P(e)=3/10
We know this to be true because out of the 10 total possibilities for the event (since we didn't replace the first card we withdrew), 3 of them are the letter 'e'.
R E P L A C E M E N T (-1 to account for the first card we withdrew)

The possibility of both events...

P(consonant then 'e')=7/11*3/10=21/110

Answer: P=21/110
