Answer:
2x = 256
Step-by-step explanation:
Your problem → 82.5 + 8(0.25x) = 338.5
82.5+8(0.25x)=338.5
⇒-256+80.25x=0
⇒2x-256=0
⇒2x=256
⇒x=256/2
⇒x=128
A coin is being flipped 400 times. What is the probability of it landing on heads at most 170 times, rounded to the nearest tenth of a percent?
"at most" is throwing me... what is the formula?
Hello!
We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.
To solve, we just multiply the two probabilities.
=0.2125≈21.3
Therefore, we have about a 21.3% chance of this event occurring.
I hope this helps!

In how many different ways can a committee with 2 members, be chosen from a group of 4 people?
Answer:
Step-by-step explanation:
We need 2 people out of a group of 4
Let's take a random person, and another to group with the random person we picked. We can group them with 3 different people ( 3 ways )
Now, repeat again, and pick a person to group with the person who is grouped with the first person (except the first person themself) (2 ways)
And repeat again, you will group them with the last person.
So in total, you have 3 + 2 + 1 = 6 ways to pick 2 people from a group of 4.
A small-business owner will lease a billboard to advertise her business. The table shows the linear relationship between the cost of leasing a billboard from Company N and the number of months the billboard is leased. The cost to lease a billboard from a different company, Company P, for x months can be found using P(x) = 100x. For what number of months will the cost of leasing a billboard be the same for both companies?
Number on months, x. - Cost, N
1 - 580
2 - 660
3 - 740
4 - 820
5 - 900
RoC = + 80
A. 9 months
B. 29 months
C. 10 months
D. 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.
Linear functionA linear function is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let P represent the cost to lease a billboard from a different company for x months. Given that:
P(x) = 100x
For the second company, let C represent the cost, hence using the table point (1, 580) and (5, 900):
C - 580 = [(900 - 580)/(5 - 1)](x - 1)
C = 80x + 500
For the same cost:
100x = 80x + 500
x = 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.

. Carl calculates the z-score corresponding to the weight 255 oz. Using the table (column.00), Carl sees the area associated with this z-score is O. Carl rounds this value to the nearest hundredth or 0. Now, Carl decides to find the percent associated with boxes less than 255 oz. so he rounds to hundredths and subtracts 0.50 - 0. %.

Amy volunteers at an animal shelter. She worked 10 hours in March, 12 hours in April, 14 hours in May, and 16 hours in June. If the pattern continues, how many hours will she work in December? Make a table to find the answer.
Answer:
28
Step-by-step explanation:
3th (March): 10
4th: 12
5th: 14
6th: 16
7th: 18
8th: 20
9th: 22
10th: 24
11th: 26
12th ( December): 28
The 4th, 5th, 6th ect are the months because i cant remember the order or how to spell rn
March (1) = 10 hours (first month, second month.. so on)
April (2) = 12 hours (+2)
May (3) = 14 hours (+2)
June (4) = 16 hours (+2)
July (5) = 18 hours (+2)
August (6) = 20 hours (+2)
September (7) = 22 hours (+2)
October (8) = 24 hours (+2)
November (9) = 26 hours (+2)
December (10) = 28 hours (+2)
Amy works 2 extra hours every month.
By December, she would have worked 28 hours.
Please help me Graph Y=f(x)
Step-by-step explanation:
f(0) = 0 , f(2) = -4 , f(4) = -2
0 = f(2x) → f(0) = f(2x) → x = 0 (0,0)
-4 = f(2x) → f(2) = f(2x) → x = 1 (1,-4)
-2 = f(2x) → f(4) = f(2x) → x = 2 (2,-2)

Suppose a rescue helicopter is 700 feet above sea level descends 300 feet to search for debris or any other signs of a submarine in trouble. When the captain does not see anything, he ascends 200 feet and stays at that altitude while he tries to get a radio signal from the submarine. A few moments later he speaks to the captain and is informed that the submarine is 122 feet below sea level. How far is the helicopter from the submarine?
Answer:
The helicopter is 722 feet from the submarine.
Step-by-step explanation:
700 - 300 = 400
400 + 200 = 600
600 - 122 = 722

The formula of Sridharacharya is used. Then the solutions of the equation are 73.19 and -13.19.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The equation is given as
[tex]\rm 4\sqrt{5x + 66} = x +10[/tex]
Squaring both sides, we have
16(5x + 66) = (x + 10)²
16(5x + 66) = x² + 100 + 20x
On simplifying, we get
x² + 100 + 20x -80x - 1056 = 0
x² - 60x - 956 = 0
On solving by formula method, we have
a = 1; b = -60; and c = -965
[tex]\rm x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\\\x = \dfrac{-(-60) \pm \sqrt{(-60)^2 - 4*1*(-965)}}{2*1}\\\\\\x = 73.19, \ -13.19[/tex]
Thus, the solutions of the equation are 73.19 and -13.19.

One year, the population of a city was 201,000. Several years later it was 237,180. Find the percent increase.
Answer:
18%
Step-by-step explanation:
% increase = new population - old population x 100
old population. 1
% increase = 237180 - 201000 x 100
201000. 1
% increase = 36180 x 100
201000
% increase = 3618000
201000
% increase = 18%
