megan hughes deposits 2100 in an account that pays simple interest. when she withdraws her money 11 months later, she receives $
USPshnik [31]

Answer:

The rate at which the account pay the deposit is 2 %

Step-by-step explanation:

Given as :

The principal amount deposited in account = $2100

The rate of interest = r % simple interest annually

The time period = 11 months = \frac{11}{12} year

The amount received = $2138.50

Now<u>, From Simple Interest method </u>

Simple Interest = \dfrac{\textrm Principal\times \textrm rate\times \textrm time}{100}

Or, Interest = \dfrac{2100\times r\times \frac{11}{12}}{100}

Or, Interest = \frac{21\times r\times 11}{12}

Or, Interest = 19.25 r

Now, Interest = Amount - Principal

So, 19.25 r = $2138.50 - $2100

Or, 19.25 r = $38.5

∴ r = \frac{38.5}{19.25}

I.e r = 2

So, rate of interest = r = 2 %

Hence The rate at which the account pay the deposit is 2 % Answer

A number cube with faces labeled from 1 to 6 will be rolled once.
kramer

Answer:

\Omega=\{1,2,3,4,5,6\}

A=\{1,2,3,4\}

Step-by-step explanation:

<u>Sample Space</u>

The sample space of a random experience is a set of all the possible outcomes of that experience. It's usually denoted by the letter \Omega.

We have a number cube with all faces labeled from 1 to 6. That cube is to be rolled once. The visible number shown in the cube is recorded as the outcome. The possible outcomes are listed as the sample space below:

\Omega=\{1,2,3,4,5,6\}

Now we are required to give the outcomes for the event of rolling a number less than 5. Let's call A to such event. The set of possible outcomes for A has all the numbers from 1 to 4 as follows

A=\{1,2,3,4\}

If you buy ice cream in 1 liter each tub cost $2 you can fill ten cones from each tub each empty cone cost 5 cents you can plan
weqwewe [10]

Answer:

You make 5.50 each 10 servings or tub you use. To find how much in a day multiply $5.50 by the number of tubs you use or number of 10 servings you sell.

Step-by-step explanation:

You buy a 1 liter tub for $2 and fill ten cones with the tub costing 10*0.05 = 0.50 for the cones. This means your total cost is $2.50 per tub (or 10 servings).

But you plan to sell the servings for 0.80 cents each. This means for 1 tub or 10 servings you'll make 10*0.8 = $8.00. You'll make $8.00.

Your profit is how much you make minus your costs.

$8.00 - 2.50 = $5.50.

You make 5.50 each 10 servings or tub you use.
