Answer:
The probability is 9/100
Step-by-step explanation:
First, we know that 70% of the students are with brown eyes. Since we have a total of 20 students, this corresponds to 70/100 * 20 = 14 students
The number of students without brown eyes is thus 20 -14 = 6 students
Now, the probability of selecting a student without brown eyes is 14/20 = 7/10 while the probability of selecting a student with brown eyes is 6/20 = 3/10
Now the probability of selecting two students without brown eyes mean, the first selected is without brown eyes and also the second selected is without brown eyes.
In probability, once we have the work and, we multiply.
So our answer here is 3/10 * 3/10 = 9/100
Answer:
The equation is a function
Step-by-step explanation:
-3x + 8 = y
Reverse the function.
y = -3x + 8
Draw a graph of y vs x (below)
To determine if the relation is a function, we can use the vertical line test:
If a vertical line crosses the graph more than once in any location, the relation is not a function.
We see that at no place will a vertical line intersect the graph more than once.
The relation is a function.
The probability that Akira will choose apple pie and Paula will choose strawberry cheesecake for dessert is; B: 0.028
<h3>What is the probability of selection?</h3>
We are told that;
There are 6 dessert options menu.
Now, Akira and Paula like all of the choices equally. Thus, probability of selecting any of the 6 menus will be; P(select 1 menu) = 1/6
Thus, probability that they select the preferred menu written in the question is; P(both select 1 menu) = 1/6 * 1/6 = 0.028

Answer:
x y
2 76
4 64
7 47
9 34
13 10
Step-by-step explanation:
If we have an initial value of 88, that would be the y intercept
The rate of change -6 which is the slope
y = -6x+88
Let x =2
y = -6(2) +88 =
-12+88
= 76
Let y = 64
64 = -6x +88
Subtract 88 from each side
64-88 = -6x
-24= -6x
Divide by -6
-24/-6 =x x=4
Let y = 46
46 = -6x +88
Subtract 88 from each side
46-88 = -6x
-42= -6x
Divide by -6
-42/-6 =x x=7
Let x =9
y = -6(9) +88 =
-54+88
= 34
Let y = 10
10 = -6x +88
Subtract 88 from each side
10-88 = -6x
-78= -6x
Divide by -6
-78/-6 =x x=13
