Terry scored 71, 80, and 86 on his first three history tests. What must terry score on the fourth test to have a mean of exactly 80
Answer:
83
Step-by-step explanation:
You are trying to find the score that gives you a specific mean. A mean is calculated by dividing the sum of the data by the amount of data. Set up in this order, with x as the fourth score, to find the answer.
[tex]\frac{71+80+86+x}{4}=80\\\frac{237+x}{4} =80\\237+x=320\\x=83[/tex]
The fourth test score must be an 83.
Answer:
83
Step-by-step explanation:
Equation: 71 + 80 + 86 + x / 4 = 80
Add 71, 80, and 86 together.
237 + x = 80
Multiply 4 to both sides (cross multiplying).
237 + x = 320
Subtract 237 from both sides.
x = 83
How would you multiply a binomial using box method
Answer:
first you divide the larger number into its separate parts. Here, 23 becomes 20 and 3.
Next, you multiply each separate part — 20 x 7 and 3 x 7.
Finally, you add all the products together. 140 + 21 equals 161, the product of 23 x 7.

There are ten kids in a class. When any two meet, each says “hi” to the other and the answer “hi” follows. Before the class starts, how many times would one hear the word “hi”?
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.
= 10 × 2
= 20hi
There will be 20 times the word hi would be heard

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.

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.

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.

E. 9
Answer: 3
Step-by-step explanation: if you had the histogram..... the first is 14 and the second is 14 too, but the first one you divide by 4 because there are only 4 lines, so that gives you 3.5
The second one you divide by 5
So, 14 divided by 5 is

Step-by-step explanation:
Step 1: Answer the question
This algebraic expression is not a polynomial therefore, none of these options match except D. The reason why it is not a polynomial is because there is a 7^x which is not a polynomial expression. The expression needs to be expressed as a 7x^2 + 2x + 1. Therefore, the answer is D.

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%

Answer: Normal distribution or Gaussian distribution.
Step-by-step explanation:
Normal distribution, this means that we will see something that remaind us to a Gaussian Bell (a curved shape that goes to zero in the extremes and has a maximum in the middle)
If we have some biased points in one side, suppose left, we will have a skewed distribution, that has some important differences with the normal distribution at the time of describe it mathematically.
A fish and wildlife management organization uses a GIS (Geographic Information System) to store and analyze data for the parcels of land it manages. All of the parcels are mapped on a grid in which 1 unit represents 1 acre. If the coordinates of the corners of a parcel are (-8, 10), (6, 17) and (2, -4), how many acres is the parcel? a. 150 acres c. 133 acres b. 125 acres d. 167 acres
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:
Using heron's formula,
area of triangle joining coordinates [tex](x_1,y_1),(x_2,y_2),(x_3,y_3)[/tex] is equal to [tex]\frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]
Let [tex](x_1,y_1)=(-8,10)\,,\,(x_2,y_2)=(6,17)\,,\,(x_3,y_3)=(2,-4)[/tex]
Area of triangle (parcel) [tex]=\frac{1}{2}|-8(17+4)+6(-4-10)+2(10-17)|\\[/tex] [tex]=\frac{1}{2}|-8(21)+6(-14)+2(-7)|\\ =\frac{1}{2}|-168-84-14|\\ =\frac{1}{2}|-266|\\ =133\,\,acres[/tex]

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
