Answer:

$5,155.7

Step-by-step explanation:

Using the compound interest formula;

Amount = 7600

Time = 7years

Rate = 5.7% = 0.057

Required

Principal

Substitute

A = P(1+r)^n

7600 = P(1+0.057)^7

7600 = P(1.057)^7

7600 = 1.4741P

P = 7600/1.4741

P = 5,155.69

Hence Lilian would need to invest $5,155.7 (to nearest ten dollars)

A survey of 260 families show that 99 had dog 76 had cat 34 had dog and cat 98 had neither a cat nor a dog nor a parakeet 8 had
Archy [21]

Answer:

<u>Option D. 21</u>

Step-by-step explanation:

The question is as shown in the attached figure 1

The Venn diagram representing the problem is the attached figure 2

D ⇒ Dog , C⇒ Cat  and P ⇒ parakeet

Let the The families had parakeet only = X

A survey of 260 families show that:

99 had dog

76 had cat

34 had dog and cat

98 had neither a cat nor a dog nor a parakeet

8 had a cat a dog and a parakeet

So,

The families had a dog and a cat only = 34 - 8 = 26

The families had a dog only = 99 - (26 + 8 ) = 65

The families had a cat only = 76 - (26 + 8) = 42

∴ X = 260 - ( 98 + 8 + 26 + 65 + 42 ) = 260 - 239 = 21

So, The families had a parakeet only = 21

<u>The answer is option D</u>
