Find the percent cost of the total spent on each equipment $36, fees $158, transportation $59

maksim [4K]

Answer: Therefore, Option 'A' is correct.

Step-By-Step explanation:

Since we have given that

Amount spent on equipment = $36

Amount spent on fees = $158

Amount spent on transportation = $59

Total amount spent by them is given by

$36+158+59=\$253$

Percent cost of equipment of the total amount is given by

$\frac{36}{253}\times 100=14.2\%$

Percent cost of fees of the total amount is given by

$\frac{158}{253}\times 100\\\\=62.45\%$

Percent cost of transportation of the total amount is given by

$\frac{59}{100}\times 100\\\\=23.3\%$

Hence, Percent cost of the total spent on each is

14%, 62%, 23%.

Therefore, Option 'A' is correct.

A restaurant owner installed a new automated drink machine. The machine is designed to dispense 530 mLof liquid on the medium si

lidiya [134]

Answer:

a.H0: μ =530mL vs. Ha: μ > 530mL

Step-by-step explanation:

-A hypothesis test will be used to provide evidence that the median is more or equal to the stated median value.

#In a normally distributed population, the mean=mode=median:

$Mean=Mode=Median=\mu$

-The null hypothesis states that the median is equal to the stated value:

$H_o:\mu=530 \ mL$

-The alternative hypothesis provides evidence that the median value is greater than the stated value:

$H_a:\mu>530\ mL$

Hence, the correct hypotheses are H0: μ =530mL vs. Ha: μ > 530mL

The Xtra Cleen Car Wash washed 256 cars in 6 hours. At that rate, how many cars can they wash in 10 hours? Select one: a. 426 b.

slava [35]

You can write and solve the proportion

$\dfrac{256\,\text{cars}}{6\,\text{hours}}=\dfrac{x\,\text{cars}}{10\,\text{hours}}\\\\x\,\text{cars}=(10\,\text{hours})\cdot\dfrac{256\,\text{cars}}{6\,\text{hours}}=426\frac{2}{3}\,\text{cars}$

The appropriate choice is ...

... a. 426
