baherus [9]

Answer:

355.2

Step-by-step explanation:

Given:

Four percent of Jennie's skin cells were burned

Total skin cells having Jennie = 3.7 x 10^10

= $3.7\times10\times10 = 370$

To find:

How man skin cells were not burned ?

Solution:

Total skin cells having Jennie = 370

Percent of Jennie's skin cells were burned = 4%

Skin cells burned from a fire = $370 \ of 4\%$

= $370\times\frac{4}{100} =\frac{1480}{100}$

= $14.8$

Remaining skin cells which not burned = 370 - 14.8 = 355.2

Therefore, 355.2 skin cells were not burned.

Natasha_Volkova [10]

The probability of obtaining at least 1 false positive if the number of employees is 500 is 0.5

Probability

In the statistics concept, the probability refers the possible number of way of happening the particular event.

Given,

A test for a certain drug has a 0.1% probability of producing a false positive.

Here we need to find the probability of obtaining at least 1 false positive if a company hired 500 drug-free employees.

In the given question, we have the following values,

=> number of employees = 500

=> Probability of false positive = 0.1%

So, the probability of obtaining at least 1 false positive is calculated as,

=> 500 x 0.1/100

=> 5 x 0.1

=> 0.5

Therefore, the probability of obtaining at least 1 false positive is 0.5.

A Walgreens purchase comes to $28. Find the total cost if a 2% sales tax is included.

OverLord2011 [107]

Answer:

The answer is $28.56

Step-by-step explanation:

To find the 2% sales tax, you need to multiply the 2% or 0.02 by 28.

Doing this will give you 0.56.

Then you add 0.56 to 28 to get 28.56, hence, $28.56 is the total cost.

Hope it helps!
