<span>Amanda possesses a total of 26 coins consisting of nickels and dimes. Let’s denote the number of nickels as x and the number of dimes as y. This gives us the equations: x = 3y - 2 or -x + 3y = 2 x + y = 26 By eliminating x, we derive 4y = 28, resulting in y = 7. Given there are 26 total coins and 7 dimes, it follows that there are 19 nickels. The quantity of nickels (19) is two less than three times the dimes amount (3(7) - 2 = 19).</span>

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
lawyer [12118]

Answer:

The male to female nurse ratio in simplest form is: 2:5

Step-by-step explanation:

Fact: A hospital has a total of 250 registered nurses.

Total number of male nurses is 100

Total number of female nurses is 250 - 100 = 150 [Total nurses minus number of male nurses]

To determine the ratio of male to female nurses in simplest terms;

A ratio indicates the relative proportions of two or more quantities.

Thus,

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

or

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

Consequently, the male to female nurses ratio in simplest form is; 2:5

PIT_PIT [11932]

Answer:

A histogram will be utilized to illustrate the right wrist size of the random sample of newborn infants.

Step-by-step explanation:

A histogram serves as a visual representation of the frequency distribution present within the sample. Given that wrist circumference can take on positive real number values, a histogram with defined class boundaries can be constructed to display the overall distribution of wrist sizes in the graph.

Furthermore, as this distribution is continuous in nature, a histogram proves to be a fitting choice compared to either a bar graph or a stem-and-leaf plot.
