Answer:

An invoice was paid an average of 20 days after it was received.

Mean =

Standard deviation =

Now we are supposed to find what percent of the invoices were paid within 15 days of receipt i.e.P(x<15)

Formula :

At x = 15

Substitute the values

Refer the z table for p value

So, p value = 0.1587

So, 15.87% of the invoices were paid within 15 days of receipt

Step-by-step explanation:

Describe how (2^3)(2^-4) can be simplified

Naddika [18.5K]

Answer:

Add the exponents and keep the bases the same. Then find the reciprocal and change the sign of the exponent

Step-by-step explanation:

When multiplying exponents with the same base number, you can add the powers. (If it was dividing, you would subtract the powers). You would then get $2^{-1}$ .

2³ = 8,
2² = 4,
2^1 = 2,
2^0 = 1

The pattern is to divide by 2. This means that $2^{-1}$ would be 1 ÷ 2 which is 1/2.

Tip: Any number to the power of -1 means to give its reciprocal.

Hope this helps!

matrenka [14]

Answer: 5 brownies

Step-by-step explanation:

cookies = 5 x $0.50 = $2.5

$15 - $2.5 = $12.5

$12.5 divided by $2.25 = $5.555

A pitcher has 16 cups of water in it. During the day, Aditi drank 21⁄2 cups, Kavitha drank 33⁄4 cups, and Rahul drank 41⁄8 cups.

zepelin [54]

Total cups of water in pitcher = 16 cups

Cups of water drank by Aditi = $2 \frac{1}{2}$ = $\frac{5}{2}$ cups

Cups of water drank by Kavitha = $3 \frac{3}{4}$ = $\frac{15}{4}$ cups

Cups of water drank by Rahul = $4 \frac{1}{8}$ = $\frac{33}{8}$ cups

Total cups of water drank by three of them

= $\frac{5}{2}$ + $\frac{15}{4}$ + $\frac{33}{8}$

LCM of 2,4 and 8 is 8.

= $\frac{20+30+33}{8}$

= $\frac{83}{8}$ cups

Number of cups left in the pitcher = $16 - \frac{83}{8}$

LCM of 1 and 8 is 8.

= $\frac{128-83}{8}$

= $\frac{45}{8}$

= $5 \frac{5}{8}$ cups

So, $5 \frac{5}{8}$ cups are left in the pitcher.
