What is the final amount if 660 is increased by 1% followed by a further 1% increase? Give your answer rounded to 2 DP.

Delvig [45]

Answer:

$673.27

Step-by-step explanation:

Initial amount = $660

1% Increase = $660*(1+1%)

1% Increase = $660+$6.6

1% Increase = $666.6

Further 1% Increase = $666.6*(1+1%)

Further 1% Increase = $666.6 + $6.666

Further 1% Increase = $673.266

Further 1% Increase = $673.27

Make a frequency distribution and find the relative frequencies for the following number set. Round the relative frequency to th

Pani-rosa [81]

Solution: We have to find the Frequency and Relative frequency of the given data:

Frequency is the number of times a number occurs.

Relative Frequency is the number of times a number occurs divided by the total number of items.

Therefore, the frequency and relative frequency are calculated as below:

Number Frequency Relative Frequency

20 1 $\frac{1}{31} \times 100 =3.2\%$

21 4 $\frac{4}{31} \times 100 =12.9\%$

22 2 $\frac{2}{31} \times 100 =6.5\%$

23 4 $\frac{4}{31} \times 100 =12.9\%$

24 3 $\frac{3}{31} \times 100 =9.7\%$

25 2 $\frac{2}{31} \times 100 =6.5\%$

26 3 $\frac{3}{31} \times 100 =9.7\%$

27 5 $\frac{5}{31} \times 100 =16.1\%$

28 3 $\frac{3}{31} \times 100 =9.7\%$

29 4 $\frac{4}{31} \times 100 =12.9\%$

Jack's mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends a

Elis [28]

Answer:

Equation: 3x + 2 = 50

# of friends: 16

Step-by-step explanation:

3 chocolates each or 3x because what "each" means is not known yet-

<em>Note: Always use x for an unknown value</em>

2 remaining chocolates-

3x + 2

50 total chocolates-

3x + 2 = 50

Remove two to keep the x alone-

3x = 48

Remove the 3 or the "Coefficient" by dividing-

48/3 = 16

x = 16

Equation: 3x + 2 = 50

# of friends: 16
