Effectus [21]

Call the amount of apples Fatima bought as x.

She gave half of the apple to Salma -> x : 2

Then she gave Maha 5 apples -> x : 2 - 5

She is left with 3 apples, so we have the equation x : 2 - 5 = 3

Solve for x :
x = (3+5) x 2 = 16.

You worked as a lifeguard this summer and earned an extra $3,000. You decided to deposit that amount into your savings account.

Nataly [62]

Answer:

The correct answer is $3300 for simple interest and $3312.24 for compound interest.

Step-by-step explanation:

Income as working as a lifeguard = $3000

We deposit the money in a bank which offers 2% interest annually for a period of 5 years.

Case 1 : Calculating simple interest for the given situation.

Amount after 5 years = 3000 + 3000 × 2 × 5 × $\frac{1}{100}$ = $ ( 3000 + 300) = $3300.

Case 2 : Calculating compound interest for the given situation.

Amount after 5 years = 3000 × $(1 + \frac{2}{100} ) ^{5}$ = $ 3312.24.

Thus the amount after 5 years amount simply is $3000 and compoundly is $3312.24

Answer:

10 square meters will have a standard deviation of 1.897.

Step-by-step explanation:

Standard deviation for n instances of a variable:

If the standard deviation for one instance of a variable is $\sigma$ , for n instances of the variable, the standard deviation will be of $s = \sigma\sqrt{n}$

The standard deviation of the number of flaws per square yard is 0.6

This means that $\sigma = 0.6$

For the 10 square yards will a standard deviation of

$n = 10$ , so:

$s = \sigma\sqrt{n} = 0.6\sqrt{10} = 1.897$

10 square meters will have a standard deviation of 1.897.
