Ответ:
Total number of shirt types available = 3
probability that the toy is dressed in a polka dotted shirt ,
= 1/3
Total number of cap varities = 2
probabiity that the toy is wearing a cowboy hat
= 1/2
Probability that the toy is dressed in a polka dotted shirt and a cowboy hat =![P_{1}\times P_{2}](/tpl/images/1123/2037/28f1a.png)
![1/3 \times 1/2 = 1/6](/tpl/images/1123/2037/1a08c.png)
Since, the type of pant is not mentioned. The probability that the toy is wearing any pant is 1. Therefore it need not be taken into consideration.
Ответ:
Option C is correct.
Step-by-step explanation:
The slope of line EF is:
Point E (-2,5) and Point F (1,3)
slope = y₂-y₁/x₂-x₁
slope = 3-5/1-(-2)
slope = -2/1+2
slope = -2/3
Since lines are parallel so, the slope of the line is same i.e. -2/3
Now we need to find y-intercept
y = mx +b
We have point (2,6)
6 = -2/3(2) + b
6 = -4/3 + b
b = 6+4/3
b = 18+4/3
b = 22/3
So, the slope-intercept form will be:
y = -2/3x + 22/3
Hence Option C is correct.
