Alice earned $622.50 in interest on her savings in the bank. Before interest, the account had $12,450. What is the approximate p

Lubov Fominskaja [6]

Answer:

Explanation:

% she earned in interest can be calculated by calculating the % of increase in the balance

We have:

Original balance = $12,450

Amount of interest = $622.5

This means that:

new balance = 12,450 + 622.5 = $13,072.5

Now, we can get the percentage of increase:

% of increase = $\frac{Value_n_e_w - Value_o_l_d}{Value_o_l_d} *100$

Substitute with the values we have to get the percentage of interest earned as follows:

% of interest earned = $\frac{13072.5 - 12450}{12450} * 100$ = 5%

Hope this helps :)

3.3.1. An urn contains five balls numbered 1 to 5. Two balls are drawn simultaneously. (a) Let X be the larger of the two number

hodyreva [135]

Answer:

Step-by-step explanation:

Given that an urn contains five balls numbered 1 to 5

Two balls are drawn simultaneously.

a) X = the larger of two numbers drawn

Assuming balls are drawn without replacement, (since simultaneously drawn)

the sample space would be (1,2) (1,3)(1,4)(1,5) (2,3)(2,4)(2,5) (3,4) (3,5) (4,5)

n(S) = 10

n(x=2) = 1,

n(x=3) =2

n(x=4) = 3

n(x=5) = 4

Larger value X can take values only as 2,3,4 or 5

X 2 3 4 5

p 0.1 0.2 0.3 0.4

-------------------------------------------

b) V = sum of numbers drawn

V can take values as 3, 4, 5, 6, 7, 8 or 9

V 3 4 5 6 7 8 9

p 0.1 0.1 0.2 0.2 0.2 0.1 0.1

Find the ratio of the similar known sides:

1.34/2 = 0.67

The smaller triangle is 0.67 the size of the larger one.

Multiply the similar sides by the ratio:

DE = 4 x 0.67 = 2.68

FE = 3 x 0.67 = 2.01
