Math Question for An assignment
Answer: y = 5/2x + 4
Step-by-step explanation:
y = 5/2x + c
1) Substitute
-6 = 5/2(-4) + c
-6 = -10 + c
-6 + 10 = c
4 = c
y = 5/2x + 4 or
y = 2.5x + 4

7. The new York Volleyball Association
invited 64 teams to compete in a tournament.
After each round, half of the teams were
eliminated.
How many teams are left after 3 rounds?
Using a geometric sequence, it is found that after 3 rounds, 8 teams are left.
In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.
The general equation of a geometric series is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem:
64 teams were invited, thus [tex]a_1 = 64[/tex].After each round, half the teams are eliminated, thus [tex]q = \frac{1}{2}[/tex].The number of teams after 3 rounds is the 4th term of sequence, as the first is the initial number(0 rounds), thus:
[tex]a_n = a_1q^{n-1}[/tex]
[tex]a_4 = 64\left(\frac{1}{2}\right)^{4-1}[/tex]
[tex]a_4 = 8[/tex]
After 3 rounds, 8 teams are left.

A model of a population of a small country is 35,000(1.03)^x. Find the current population if x equals four years since the last census.
Based on the model of the population and the amount of years that have passed, the current population is 39,393 people.
The model of the population is:
= 35,000 x (1.03)^ x
If x is 4 years, slot this into the model to get:
= 35,000 x 1.03⁴
= 35,000 x 1.12550881
= 39,393 people
In conclusion, the current population is 39,393 people.

Step-by-step explanation:
(I'LL GIVE BRAINLIEST) Carson wanted to buy a cowboy hat that cost $49.95 (with tax) at a souvenir shop. He knew he had $18 at home already, and he could earn $10 per lawn by mowing lawns for his neighbors. He came up with the following expression to figure out how many lawns he would need to mow in order to purchase the hat: M = 10w + 18 with "w" being the number of lawns he would need to mow and "M" being the total amount of money he has.
Carson then determined he would need to mow 3 lawns by completing the follow steps:
50 = 10w + 18
32 = 10w
3.2 = w
Identify Carson's error. Explain the steps to correctly solve for how many lawns Carson needs to mow. Be sure to clearly state the correct answer.
Answer:
so Carson's problem was at the end, since the neighbors are paying 10$ PER DAY, and 3 days work would only earn him 30$ meaning at the end he would be a dollar short, technically, he needs to work exactly 3.2 days, or...
let's say he works 4 hrs a day
1 Day = 4Hr
3.2 Days = X
X = 3.2 × 4
= 12.8 Hrs
so Carson needs to work 3 days and an extra 48 Minutes
A triangle with an area of 370 square inches
has a height that is 6 less than 8 times its
base. Find the base and height, in inches, of
the triangle.
Base=
Height=
Answer:
Step-by-step explanation:
Area of triangle = 1/2 (base × height)
Given, area of a triangle is 192 sq ins. and its height is 8 ins less than its base.
Then, let base = b, height = b-8
Hence, 1/2 (b)*(b-8) = 192
Above equation; “times 2”,
(b)*(b-8) = 384
b^2 - 8b - 384 = 0
(b+16)(b-24)=0

The sum of three consecutive even integers is -78. What is the smallest integer? Show all working outs (5)
Answer:
The smallest integer is -27 and the integers are -27, -26, and -25
Step-by-step explanation:
We can represent this with:
x + x - 1 + x - 2 = -78
Simplify.
3x - 3 = -78
Add 3 to both sides.
3x = -75
Divide both sides by 3.
x = -25
So, the first integer is -25.
Subtract two to get the smallest integer.
-25 - 2 = - 27

Members of a softball team raised $1319.25 to go to a tournament. They rented a bus
for $776.50 and budgeted $41.75 per player for meals. Write and solve an equation
which can be used to determine p, the number of players the team can bring to the
tournament. Giving 100 points please help
Answer:
13 players
Step-by-step explanation:
Money Raised=RentedBus+Meals
1319.25=776.50+41.75p (p is for the number of players)(Now we solve for x)
Subtract 776.50 from both sides: 542.75=41.75x
Divide both sides by 41.75: 13=x
Remember that x is for the number of players so there'll be 13 players going to the tournament.
Answer:
1319.25=776.50+41.75p
13 players

We expect that students who do well on the midterm exam in a course will usually also do well on the final exam. Gary Smith of Pomona College looked at the exam scores of all 346 students who took his statistics class over a 10-year period. The least-squares line for predicting final-exam score from mid-term exam score was γ=46.6 + 0.41x.
Octavio scores 10 points above the clas mean on the midterm. How many points above the class mean do you predict that he will score on the final. (Hint: what is the predicted final-exam score for the class mean midterm score of x-bar?) This is an example of regression to the mean, the phenomenon that gave "regression" its name: students who do well on the midterm will on average do less well on the final, but still above the class mean.)
Using the model equation, the predicted mean score on the final given a score of 10 points above the class mean in the mid term exam is 50.7
The Least - Square Regression equation which models the relationship between midterm and final exam score is :
γ=46.6 + 0.41xx = 10 points ; substitute the value of x = 10 into the regression equation ;
γ=46.6 + 0.41(10)
γ=46.6 + 4.1
γ = 50.7
The number of points above the mean he'll score in the final exam is predicted to be 50.7

Which pair of angles are supplementary?
Answer:
1 and 7
Step-by-step explanation:
supplementary means that they add up to 180º
1,3 5,6 1,7
2,4 7,8 2,8
1,2 5,7 3,5
3,4 6,8 4,6
There are still some more but my hands are tired of typing.
Answer:
A: 1 and 7
Step-by-step explanation:
when 2 angles are put next to each other on a straight line with a line going through the middle those two angles always add to 180 since 180 is equal to a straight line.
supplementary angles are 2 angles that together make 180.
out of the options given, all of them except 1 and 7 are equal angles and as a result would not add to 180. if you put angles 1 and 7 on a straight line together, they do, thus the answer is A, aka 1 and 7.
