Match each time with a time in the box.
BigorU [14]
If you would like to match each time with a time above, you can do this using the following steps:

a 3h 18m 7s = 11887s<span>
3h = 3 * 60m = 180m; 180m + 18m = 198m; 198m = 198 * 60s = </span>11880s; 11880s + 7s = 11887s

b <span> 8300min = approximately 5 days 18 hours
8300min = 8300 * 60s = </span>498000s
8300 min / 60 min = 138h 20min; 138h / 24h = 5 days 18 hours 20min

c 1461 days
1461 days = 1461 * 24 hours = 35064 hours

d <span>44640min. = 31 days
</span><span>44640min / 60min = 744 hours; 744 hours / 24 hours = 31 days

e </span><span>10:21:2.5

2^8-10-15÷3<br><br> can you help me plzzzz
GenaCL600 [577]

Answer:

241

Step-by-step explanation:

Simplify the following:

2^8 - 10 - 15/3

The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:

2^8 - 10 + -5

2^8 = (2^4)^2 = ((2^2)^2)^2:

((2^2)^2)^2 - 10 - 5

2^2 = 4:

(4^2)^2 - 10 - 5

4^2 = 16:

16^2 - 10 - 5

| 1 | 6

× | 1 | 6

| 9 | 6

1 | 6 | 0

2 | 5 | 6:

256 - 10 - 5

256 - 10 - 5 = 256 - (10 + 5):

256 - (10 + 5)

10 + 5 = 15:

256 - 15

| 2 | 5 | 6

- | | 1 | 5

| 2 | 4 | 1:

Random sample size of 81 are taken from an infinite population whose mean and standard deviation are 200 and 18, respectively. T
Ugo [173]

Answer:

the  mean and standard error of the mean are 200 and 2 respectively.

Step-by-step explanation:

Given that ;

the sample size n = 81

population mean μ = 200

standard deviation of the infinite population σ = 18

A population  is the whole set of values, or individuals you are interested in, from an experimental study.

The value of population characteristics such as the  Population mean (μ), standard deviation (σ) are said to be known as the population distribution.

From the given information above;

The sample size is large and hence based on the central limit theorem the mean of all the means is same as the population mean 200.

i.e

\mu = \bar \mu_x = 200

∴ The mean = 200

and the standard error of the mean can be determined via the relation:

\mathbf{standard \ error \ of \ mean = \dfrac{\sigma}{\sqrt {n}}}

\mathbf{standard \ error \ of \ mean = \dfrac{18}{\sqrt {81}}}

\mathbf{standard \ error \ of \ mean = \dfrac{18}{9}}

\mathbf{standard \ error \ of \ mean =2}

Therefore ; the  mean and standard error of the mean are 200 and 2 respectively.
