Answer:</h2>
<em>The probability of rolling a 3 is 1/6.</em>
The probability of rolling a 7 is 0%.
<u>The probability of rolling a 3 or 4 is 1/3.</u>
<h3>
Step-by-step explanation:</h3>
The sides on a dice are 1, 2, 3, 4, 5, and 6. They all have a 1/6 chance of rolling.
So,
<em>There is a 1/6 chance of rolling a 3.</em>
<u>There is a 1/3 chance of rolling a 3 or 4.</u>
<u />
Since there is no 7 on a dice, there is a 0% chance of rolling it.
2.75 * 12 = 33.
If the Sanchez family is using 2 3/4 (or 2.75) tubes of toothpaste and there are 12 months in a year, we use the equation above and get 33 as our answer.
x/240 = 82/100
240 : 100 = 2.4
so 240 is divided with 2,4 giving 100, this will work with 82 too. So, 82 × 2.4 = 196,8
Answer : x = 196,8
prove :
196,8/240 = 82/100 = 41/50
see the picture
(x-7)^2+y^2=225={x-7- 225-y2}
x=225-y2+7
Answer:
Y = -0.09594X + 74.35629
Step-by-step explanation:
Given the data :
Job average annual salary (X) :
81
96
70
70
70
92
92
100
98
102
Stress tolerance (Y) :
69
62
67.5
71.3
63.3
69.5
62.8
65.5
60.1
69
Using technology, the linear model Obtian by fitting the given data is :
Y = -0.09594X + 74.35629 ;
Where ;
Y = stress tolerance (dependent variable)
X= Average annual salary (Independent variable)
Slope = 0.09594
Intercept = 74.35629
