The ratio of women to men working for a company is 5 to 7. If there are 140 men working for the company, what is the total numbe
Thepotemich [5.8K]
So women:men=5:7
for every 5 units of women, there are 7 units of men so
there are 140 men and that equals 7 units so
140=7 units
solve for 1 unit
140/7=20
1 unit=20
women=5 units
5 times 20=100
women=100
total=women+men=100+140=240
another way would be to add up the units (5+7=12) and multiply by the amount per 1 unit

Convert -3pi/10 to degrees
ipn [44]

we know there are 180° in π radians, how many degrees then in -3π/10 radians?

\bf \begin{array}{ccll} degrees&radians\\ \cline{1-2} 180&\pi \\\\ x&-\frac{3\pi }{10} \end{array}\implies \cfrac{180}{x}=\cfrac{\pi }{~~-\frac{3\pi }{10}~~}\implies \cfrac{180}{x}=\cfrac{\frac{\pi}{1} }{~~-\frac{3\pi }{10}~~} \\\\\\ \cfrac{180}{x}=\cfrac{\pi }{1}\cdot \cfrac{10}{-3\pi }\implies \cfrac{180}{x}=-\cfrac{10}{3}\implies 540=-10x\implies \cfrac{540}{-10}=x \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill -54=x~\hfill

sesenic [268]

Answer:  b. 1.94

Step-by-step explanation:

For binomial distribution model , the formula to find standard deviation is given by :-

\sigma=\sqrt{np(1-p)}

Given : The portability that the offices she visits will eventually purchase her product: p=0.25

The number of offices she visited = 20

We assume that the binomial is an appropriate model for the number of offices that make a purchase.

Then, to find the distance of  the possible number of sales Tina could observe from the overall mean number of sales we find standard deviation.

\sigma=\sqrt{np(1-p)}\\\\=\sqrt{20(0.25)(0.75)}\\\\=\sqrt{3.75}=1.9364916731\approx1.94

Hence, the correct answer is option (b).
