The 65 tens blocks can be solved by doing 65x10 which is 650. the 7 ones blocks can be solved by 1x7 which is 7 so you then add up 650 and 7 to get a grand total of 657
Part A: 12 times it was heads out of 20. So to find the experimental probability, you would take the number of times it landed heads and divide it by the number of times it was fliped. So the answer to Part A would be 12/20 = 3/5
Part B: Theoretical probability is when an event is completly random, the times something should happen out of so many times is the theoretical probability. For example, in a completly random world where everythin were to be random, a coin flipped would land exacfly 1/2 the time heads and 1/2 the time tails.
Hope this helps!
Answer:
<u>Distributive Property</u>
Step-by-step explanation (if you were to show the steps):
(x+2)(y+z) <u>(first expression)</u>
xy + xz + 2y + 2z <u>(Distributive Property of Multiplication)</u>
yx + 2y + zx + 2z <u>(use the Commutative Property of Addition and Commutative Property of Multiplication to group xy (also known as yx) and 2y together, and to group xz (also known as zx) and 2z together)</u>
y(x + 2) + z(x + 2) <u>(use factoring to get the rewritten expression at the end)</u>
Answer:
y= -10
Step-by-step explanation:
y=3x-4
y=3*(-2)-4
y= -6-4
y= -10
Answer:
2x + 3y = $54
Step-by-step explanation:
Standard Form ~ Ax + By = C
A and B in this case are just going to be numbers, they are just for substitution purposes.
Since x is fruit flavored candy and y is Chocolate, we can substituce the Fruit for A and Chocolate for B.
Now, we have 2x + 3y = C
The C is going to be the total cost. Therefore we have ~
2x + 3y = $54
