Step-by-step explanation:
so basically for this on u have to draw this on graph every first number of the coordinate is on x axis e.g . (7,0) 7 is on x axis and 0 is on Y axis. you can use tracing paper for this which will be more helpful as u can trace the shape and move it half way.
As u rotate it around the origin so u just turn it half way. eg I drawn it on the picture.
hope this make sense :)
The expectation of this game is that the house (casino) takes in roughly $3.83 every time someone plays, and after enough plays, they will typically always win.
We can determine this case by looking at all of the possibilities and how much you can win or lose off of each. There are 36 total cases for what can happen when we roll the dice. Of those 36 cases, 9 of them produce positive winnings and 27 of them produce losses.
To calculate the winnings, we need to look at what type they are. 6 of them will be 7's which earn the gambler $20. 3 of them would be 4's, which earns the gambler $40.
6($20) + 3($40)
$120 + $120
$240
Then we look at the losses. This is easier to calculate since every time the gambler loses, he losses exactly $14. There are 27 of these instances.
27($14)
$378
Now we can look at the average loss per game by subtracting the losses from the gains and finding the average.
(Winnings - losses)/options
($240 - 378)/36
$3.83
Answer:
276 miles, $ 20.148
Step-by-step explanation:
Given:
Donald Duck's car travels in 1 gallon gas = 30 miles
Cost of 1 gallon = $ 2.19
Question asked:
Distance travel in 9.2 gallons = ?
Cost of 9.2 gallons of gas = ?
Solution:
By applying unitary method:
His car travels in 1 gallon = 30 miles
His car will travel in 9.2 gallons = 
= 276 miles
Cost of 1 gallon = $ 2.19
Cost of 9.2 gallons = 
= $ 20.148
Answer:
The answer is %14.
Step-by-step explanation:
Lets consider that there are 100 people attending to the gym class.
Then we know that 45 person is going to Zumba training.
%5 of people attends all the classes in the gym. Means 5 person attends all the classes. Lets subtract them from 45 person. 45-5=40. We have 40 person left.
%15 of people attends Zumba and yoga, %21 of people attends Zumba and weight lifting. First we need to substract first %5 which attends all classes in the gym from both clusters.
21-5=16 and 15-5-10
We have 10+16=26 person which attends Zumba and one more class. Lets subtract those from Zumba cluster 40-26=14. 14 person is only attending to Zumba classes
