Answer:

On the other hand, if rates are very low, gold may potentially benefit as it keeps the opportunity cost of holding gold to a minimum. Of course, gold could also move higher even with high interest rates, and it could move lower even during periods of ultra-low rates. Monetary policy can also affect the gold price.

Jlenok [28]

Answer:

So, the present accumulated value is, $ 49557.69

Step-by-step explanation:

According to the question, payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. So, present accumulated value, =

$ \sum_{x = 1}^{60}670 \times (1 + \frac{8}{12 \times 100})^{x}

= $ (670 \times (\frac {(1 + \frac {2}{300})^{61} -  ( 1 + \frac{2}{300})}{\frac{2}{300}})

\simeq $ 49557.69

So, the present accumulated value is, $ 49557.69

The weights (in pounds) of 30 newborn babies are listed below. Find p16. 5.5 5.7 5.8 6.0 6.1 6.1 6.3 6.4 6.5 6.6 6.7 6.7 6.7 6.9
navik [9.2K]

Answer:

P16= 6.1

Step-by-step explanation:

We have given:

The weights (in pounds) of 30 newborn babies are listed below. Find p16. 5.5 5.7 5.8 6.0 6.1 6.1 6.3 6.4 6.5 6.6 6.7 6.7 6.7 6.9 7.0 7.0 7.0 7.1 7.2 7.2 7.4 7.5 7.7 7.7 7.8 8.0 8.1 8.1 8.3 8.7

To find the P(16) first we have to sort out our data.

Our data is already in  sorted form.

Now apply the formula to find the P16 which means 16th percentile.

P(n)/100

where P= 16

and n = 30

=16(30)/100

=480/100

= 4.8 ≈ 5

If you round it to 5 you get P16 = 6.1....

4 rational numbers that are not whole Numbers
Amiraneli [1.4K]

Answer:

see below (I hope this helps!)

Step-by-step explanation:

Whole numbers are the integers that are greater or equal to 0. Basically, they are 0, 1, 2, 3....

Rational numbers can be written in the form a / b (where b ≠ 0 and a and b are integers (integers are ..., -1, 0, 1, ...))

Therefore, 4 rational numbers that are not whole numbers could be -5, -1, 0.5, and 3/4.
