Answer:

0.9295 = 92.95% probability of getting someone who tests negative, given that he or she did not have the disease.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

11 + 145 = 156 people did not have the disease.

Out of those, 145 tested positive. So

p = \frac{145}{156} = 0.9295

0.9295 = 92.95% probability of getting someone who tests negative, given that he or she did not have the disease.

It costs $20 plus $1.50 per hour to rent a golf cart.
jeka57 [31]
$20 base fee + ($1.50 per hour × X hours rented) = Y the overall price

20+(1.50×X)=Y

Example:
Let's say the golf cart is rented for 3 hours.
X = 3

$20 base fee + ($1.50 per hour × 3 hours)
20+(1.50×3)
20+4.50= $24.50

So in this example Y=$24.50

In a hospital, there are 250 registered nurses. 100 of the nurses are males. What is the ratio of male nurses to female nurses i
Dimas [21]

Answer:

The ratio of male nurses to female nurse in lowest terms is: 2:5

Step-by-step explanation:

Given: In a hospital, there are  total 250 registered nurses.

Number of nurses are males = 100

Number of nurses are females = 250 - 100 = 150  [ Total nurses - number of male nurses]

To find the ratio of male nurse to female nurses in lowest terms;

A ratio shows that the relative sizes of two or more values.

Then,

\frac{Number of male nurses}{Number of female nurses} = \frac{100}{250}

or

= \frac{100}{250} =\frac{10}{25} =\frac{2}{5} = 2:5

Therefore, the ratio of male nurses to female nurses in lowest terms is; 2 :5
