Step-by-step explanation:

Mean:

Before replacing = 464/8 = 58

After replacing 42 with 98 = 520/8 = 65

Mode:

Before replacing = 42

After replacing 42 with 98 = 98

Median:

25, 42 , 42 , 47, 55 , 59, 96,98

Before replacing = 47+55/2 = 51

25, 42 , 47, 55 , 59, 96,98 , 98

After replacing 42 with 98 = 55+59/2 = 114/2 = 57

A jeweler is dividing

tatuchka [14]

Question:

A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32

Answer:

Option D

Each lot weight $\frac{3}{32}$ part of pound

Solution:

Given that,

A jeweler is dividing 3/8 of a pound of rubies among 4 lots

To find: part of a pound each lot weigh

From given,

$\frac{3}{8} \text{ of a pound } = 4 lots$

Let "x" be the part of a pound each lot weigh

Therefore,

$\frac{3}{8} \text{ of a pound } = 4 lots\\\\"x" part = 1\ lots$

This forms a proportion and solve by cross multiplying

$\frac{3}{8} \times 1 = 4 \times x\\\\x = \frac{3}{32}$

Thus, each lot weight $\frac{3}{32}$ part of pound

Find the annual percentage yield (APY) in the following situation. A bank offers an APR of 4.8% compounded daily. The annual per

sweet-ann [11.9K]

Answer:

4.92%

Step-by-step explanation:

First of all, recall that if you increase a number C in x%, then you will have $C+\frac{x}{100}C=C(1+\frac{x}{100})$

So increasing a number in x% is equivalent to multiply it by (1+x/100)

Now, suppose you have deposited $C where C is any amount > 0

If the bank offers an APR of 4.8% compounded daily, it means that your money increases $\frac{4.8}{365}\%=\frac{0.048}{365}$ daily.

So, after 365 days you will have

C multiplied by (1+0.048/365) 356 times, that is

(1) $C(1+\frac{0.048}{365})^{365}=C(\frac{365.048}{365})^{365}$

Now, you want to find a value x, such that C increased in x% equals the amount in (1).That would be the percentage your money increased in one year (APY)

$C(\frac{365.048}{365})^{365}=C(1+\frac{x}{100})\Rightarrow x=100[(\frac{365.048}{365})^{365}-1]$

Computing this amount, we get

x = 4.92 rounded to the nearest hundreth.

And the bank is offering an APY of 4.92%
