A pie chart is a graphical chart that is circular in shape. The sum of degrees in a pie chart is equal to 360 degrees.

The portion of football in degrees is 72 degrees

From the question,

The total number of hours for each sports activity = 50 hours

The total number of hours spent on football = 10 hours

The formula to calculate the portion for football in degrees is given as:

(Number of hours spent on football / Total number of hours) x 360 degrees

10 hours/ 50 hours x 360 degrees

= 72 degrees

Therefore, the portion of football in degrees is 72 degrees

Allisa [31]

Answer:

Step-by-step explanation:

Given

there are 50 winning number out of which 40 get $ 100 each and 10 wins $ 1000 .

let x denotes the winning from a randomly selected ticket

$x=100\ with\ Probability\ \frac{40}{5000}$

$x=1000\ with\ Probability\ \frac{10}{5000}$

Expected value is given by

$E(x)=100\times \frac{40}{5000}+1000\times \frac{10}{5000}$

$E(x)=0.8+2=2.8$

and Expected return is given by

$=100\times \frac{40}{5000}+1000\times \frac{10}{5000}-5$

$=2.8-5=$ -2.2$

Help me with this,i really forgot how to do these type of questions

Montano1993 [528]

Work=speed times time (my equation to help me figure it out)

ok, 10 men take 84 days to complete a job
therefor, each man completes 1/10 of the job in 84 days
each man does 1/840 of the job per 1 day

so, if we had 5 more, or 15 men

15 times 1/840 times xdays=1 job complete
15/840 times xdays=1job
times both sides by 840/15
xdays=840/15
xdays=56
56 days it would take
