Answer:
Step-by-step explanation:
From the information given:
We can compute the required calculations into a table as shown below.


5 14 14/65 = 0.22 14
6 19 19/65 = 0.29 19+14 = 33
7 12 12/65 = 0.19 33+12 = 45
8 9 9/65 = 0.14 45 + 9 = 54
9 <u> 11 </u> 11/65 = 0.17 54 + 11 = 65
65
Note: that the relative frequency is determined by dividing each value in the frequency by the total of the frequency.
Answer:
u=95
Step-by-step explanation:
To solve this problem we need to isolate 'u' variable using properties of equation.
Lets multiply by -9 the whole equation
u - -23=-8*9
Remember keys features of algebra:
- * - = +
- * += -
+ * - = -
+ * + =+
So, our equations becomes>
u+23=-72
Lets now subtract 23 to both sides
u-23=-72-23
We have u=95
If one U.S. dollar is as much as 1.68 Swiss francs, then 79,00 U.S. dollars will be as much as 79,00 * 1,68, which is 132,72 Swiss francs.
I hope it will help :)
I will go about solving this using the elimination method.
First, convert the equations.
10x + y = -20
4x + y = -12
Second, find the easiest variable to get rid of and get rid of it! (In this case, y) We will subtract to get rid of y.
6x = -8
Third, you want to solve the equation.
6x = -8 (divide by 6)
x =

Fourth, solve for y by inserting the answer for x into one of the equations.
10(

) + y = -20

+ y = -20 (subtract

)
y =

The solution for this system of equations is (

).
