There were 100 total students surveyed.
There are 41 freshman students that have an ATM card.
The probability is the number of freshman that have an ATM card over the total number of students.
The probability becomes 41/100
Now divide the fraction to get the decimal answer:
41/100 = 0.410
(3.25) or (2 4/6) should be your answer let mi kno if im right
Explanation:
The starting system is:
{
0.4
x
−
0.1
y
=
2
0.2
x
+
0.5
y
=
1
If we multiply the second equation by
−
2
the coefficients of
x
will be opposite numbers:
{
0.4
x
−
0.1
y
=
2
−
0.4
x
−
y
=
−
2
Now we can add both sides of the equations to get an euation of 1 variable:
−
1.1
y
=
0
y
=
0
Now we have to substitute the calculated value of
y
to calculate
x
:
0.4
x
=
2
x
=
2
0.4
=
20
4
=
5
Answer:
The solution of this systemm is:
{
x= 5
Y=0
I hope that helps let me know if you have questions.
Answer:
<u>-1</u>
5
Step-by-step explanation:
You have to use this formula if you want to know the slope: <u>Y2 - Y1</u>
X2 - X1
<u>Y2 - Y1</u>
X2 - X1
<u>-1 - 0</u>
5 - 0
<u>-1</u>
5
Really really sorry if this is incorrect!!! :)
