Answer:

y= 90

Step-by-step explanation:

64−(3y+8y+y)÷40=37

Combine terms in the parentheses

64−(12y)÷40=37

Subtract 64 from each side

64-64−(12y)÷40=37-64

-(12y)÷40=-27

Multiply each side by 40

-(12y)÷40*40=-27*40

-12y =-1080

Divide each side by -12

-12y/-12 = -1080/-12

y =90

Answer:

y= 90

Step-by-step explanation:

64−( 3y+8y+y 40 )=37 64+ −3 10 y=37 −3 10 y+64=37

Step 2: Subtract 64 from both sides.

−3 10 y+64−64=37−64 −3 10 y=−27

Step 3: Multiply both sides by 10/(-3).

( 10 −3 )*( −3 10 y)=( 10 −3 )*(−27) y=90

3x^3-2x^2-147x+98=(ax-c)(bx+d)(bx-d) where a,b,c and d positive integers. Work out the value of a,b,c and d
Alexxx [7]

Expand the right side:

(ax-c)(bx+d)(bx-d)=(ax-c)(b^2x^2-d^2)

=ab^2x^3-b^2cx^2-ad^2x+cd^2

Notice that 98 = 2 * 7 * 7, so we have c=2 and d=7.

Then

-ad^2=-147\implies a=\dfrac{147}{49}=3

and

ab^2=3\implies b^2=1\implies b=1

Prisha rolls a fair number cube multiple times and records the result of each roll. Her results are shown in the table.
Leona [35]

Answer:

The experimental probability of rolling a 3 is greater than the theoretical probability of rolling a 3

Step-by-step explanation:

* Lets explain the difference between the theoretical probability and

 experimental probability

- Theoretical probability is what we expect to happen

- Experimental probability is what actually happens when we try it out

- Both of them calculated by the same way, the number of possible ways

 an outcome can occur divided by the total

* Lets solve the problem

- The table has two column;

# Number Cube             # Observed Frequency

           1                                           18

           2                                          16

           3                                          24

           4                                          26

           5                                          16

           6                                          20

        Total                                      120

∵ The experimental probability of rolling a 3 = 24/120 = 1/5 = 0.2

∴ The experimental probability of rolling a 3 = 0.2 = 20%

∵ The theoretical probability of rolling a 3 = 1/6

∴ The theoretical probability of rolling a 3 = 0.1666 ≅ 17%

∵ 20% is greater than 17%

∴ The experimental probability of rolling a 3 is greater than the

  theoretical probability of rolling a 3
