Elana is programming a video game. She needs to simulate the power up that the player gets when they reach a certain level. The computer can run a program to return a random integer between 1 - 100. Elana wants the best power up to be rewarded 15% of the time. Explain how Elana can use the computer to simulate the player getting the best power up at least 2 out of 3 times
Answer:
You have to define when the power should be pushed up using the 'For' statement and let an impulse be sent to the CPU to increase power by 15%
Step-by-step explanation:
We use certain functions in writing computer programs.
For the 'For' statement ; we can define conditions. First Elana would define at what point does she want the player power to get the best power.
For example if she defines that when the player has played for 2hours return an integer 1 for instance.
This value returned will now send a pulse to the CPU to increase its power to 15%.
If the player plays for further 1hour she can define the count to be 10 and so send another pulse to the CPU to increase the processing power by additional 15%

A delivery service claims that orders arrive before noon 90% of the time. If Amy uses the delivery service 20 times, how many times can she predict the deliveries will arrive before noon? Is the claim accurate if her packages arrive after noon 4 times?
Answer:
They claim that 90% of the times, the orders arrive in time.
Then, out of N orders, (90%/100%)*N of them will arrive in time.
Here we have that N = 20
then the number that arrives in time is:
(90%/100%)*20 = 18
Now, experimetally we see that 4 times her packages arrived after noon (so 16 times the packages arrived in time), so we can calculate the experimental percentage as:
(X/100%)*20 = 16
X = (16/20)*100% = 80%
so the percentages doesn't match, so it the claim is not really accurate, but this is a small sample, so if the number of times that she uses the delivery increases, we may see that the experimental percentage gets closer to the claimed percentage.
Use the distributive property to expand Negative 4 (Negative two-fifths + 3 x). Which is an equivalent expression?

Step-by-step explanation:
Negative 4 (Negative two-fifths + 3 x) is StartFraction 8 over 5 EndFraction minus 12 x, option D is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is Negative 4 (Negative two-fifths + 3 x).
-4(-2/5+3x)
We solve the equation by using distributive property.
Now apply distributive property

A canvas shopping bag has a mass of 600 grams. When 5 cans of equal mass are put into the bag, the filled bag has a mass of 4 kilograms. What is the mass of each can in grams?
Answer:
Mass of each can = 680 grams
Step-by-step explanation:
Mass of a canvas shopping bag = 600 grams Or [tex]\frac{600}{1000}[/tex] Kilograms
= 0.6 Kilograms
Let the mass of each can = w Kilograms
Then the mass of 5 cans = 5w Kilograms
Total mass of the bag when these cans were kept in the bag = 4 Kilograms
(5w + 0.6) = 4
5w + 0.6 - 0.6 = 4 - 0.6
5w = 3.4
w = [tex]\frac{3.4}{5}[/tex]
= 0.68 Kilograms
= [tex]0.68\times 1000[/tex]
= 680 grams
Therefore, mass of each can = 680 grams

Answer:
c. 133 acres
Step-by-step explanation:
Given: coordinates of the corners of a parcel are (-8, 10), (6, 17) and (2, -4)
To find: area of the parcel
Solution:

y + 11 > -9
y - 17 Less-than-or-equal-to -46
30 Less-than-or-equal-to y + 5
y + 20 > -30
Answer:
Let's check one by one:
y + 11 > -9
-25 + 11 > -9
-14 > -9 (wrong)
y - 17 <= -46
-25 - 17 <= -46
-42 <= -46 (wrong)
30 <= y + 5
30 <= -25 + 5
30 <= -20 (wrong)
y + 20 > -30
-25 + 20 > -30
-5 > -30 (Right)
=> Last option is solution
Hope this helps!
:)
The required inequality that contains -25 in its solution is y +20 > -30.
Option D is correct.
Number of inequality is given y + 11 > -9 , y - 17≤ -46, 30 ≤ y + 5, y + 20 > -30, the inequality that contains -25 to its solution of set to be determine.
What is inequality?Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
1) y + 11 > -9
y >-20
It does not contain -25. in its solution set.
2) y - 17≤ -46
y ≤ -29
It does not contain -25. in its solution set.
3) 30 ≤ y + 5
25 ≤ y
It does not contain -25. in its solution set.
4) y + 20 > -30
y > -50
It does contain -25 in its solution.
Thus, the required inequality that contains -25 in its solution is y +20 > -30.

Answer: 20
Step-by-step explanation:
From the question, there are ten kids in a class and when any two meet, each kid says “hi” to the other kid and the answer “hi” follows.
The number hi one would hear before the class starts would be 10 multiplied by 2 because there are 10kids and 2 hi whenever the kids greet.

Please help!! Urgent! Due soon! - A bedroom is initially squat-shaped with each side x feet long. The room is then expanded so that the length of the room is increased by 3 feet, and the width increased by 4 feet. Choose the expression which represents how much bigger the area of the new bedroom is than the old bedroom.
Answer:
The second one; x²+7x+12
Step-by-step explanation:
So, since the beginning lengths of the square is x and x, the area of the square is x².
But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).
Finally, you would multiply them together to get the equation you would use to find the new area.
For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
Here's the work:

Five times the sum of a number and 3 is the same as 3 times the difference of twice the number and 1.
What is the number?
Answer:
12
Step-by-step explanation:
5(x+3) = 3(2x-1)
5x+15 = 6x-3
15-3 = 6x-5x
12 = x
x = 12
The number should be 12.
Given that,
Let us assume the number be x.Five times the sum of the number & 3 should be the same because 3 times is the difference of the twice of the number and 1.Based on the above information, the following equation should be made:
5(x+3) = 3(2x-1)
5x+15 = 6x-3
15-3 = 6x-5x
12 = x
x = 12
Therefore we can conclude that the number is 12.
