12x−y−8=10 in slope incerpet form ( dont have to simply )
Answer:
y = 12x -18
Step-by-step explanation:
12x−y−8=10
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
Solve for y
Add 8 to each side
12x−y−8+8=10+8
12x -y = 18
Subtract 12x from each side
-y = -12x +18
Divide by -1
y = 12x -18
Answer:
y=12x-18
Step-by-step explanation:
12x-y-8=10
12x-y=18
-y=-12x+18
y=12x-18
David bought a box of peanuts. The box weighed 3/4 of a pound. He ate 1/5 of a pound of peanuts that night. How much did David have left over?
Answer:
3/4=75%
75%/5=15%
15% of a pound is 0.15 pound. 75% of a pound is 0.75 pound. If David ate 0.15 pound of the 0.75 pound then he has 0.60 pound left. 0.75-0.15=0.6

How many terms are in the expression 32abc + 17ab -14bc -5?
Hey there! I'm happy to help!
A term is anything in an expression that is added. If you see a - sign it is still a term it is just adding a negative number.
We are adding 32abc, 17ab, -14bc, and -5, so this is four total terms.

If P is between L and A, PL = x + 4, PA = 2x − 1, and
LA = 5x − 3, then x =____ and LA =____ .
Answer:
x=3 LA=12
Step-by-step explanation:
PL plus PA is equivalent to LA. So, (x+4)+(2x-1)=5x-3, which can be rewritten as 3x+3=5x-3. Now we can add 3 to both sides to get 3x+6=5x and subtract 3x from both sides to get 6=2x. Now we divide by 2 on both sides to get x, which is 3, and we can plug that into the equation for LA. So we get 5(3)-2=LA. LA equals 12.
Steps to solve (x+4)+(2x-1)=5x-3:
1: (x+4)+(2x-1)=5x-3
2: 3x+3=5x-3 Rewrite equation
3: 3x+6=5x Add 3 to both sides
4: 6=2x Subtract 3x from both sides
5: 3=x Divide by 2 on both sides
The value of x is 3 and the value of LA is 12.
PL = x + 4,
PA = 2x − 1,
LA = 5x − 3.
Since P is between L and A, then the equation to get x will be:
PL + PA = LA
(x + 4) + (2x - 1) = (5x - 3)
Open the bracket
x + 4 + 2x - 1 = 5x - 3
Collect like terms
3x + 3 = 5x - 3
5x - 3x = 3 + 3
2x = 6
x = 6/2
x = 3
LA = 5x - 3
LA = 5(3) - 3
LA = 15 - 3.
LA = 12

The world population is estimated to be 7.8 billion in 2020, and growing at an instantaneous rate of 1.05%. (a) Estimate the population in 2100 if the growth rate remains constant at 1.05%. (b) Estimate the population in 2100 using the logistic function, assuming a carrying capacity of 13 billion. Also, what will be the growth rate in 2100
Answer:
Population in 2100 is 17.99 billion.
Step-by-step explanation:
The population of the world in 2020 = 7.8 billion.
The growth rate = 1.05%
Now find the population after 2100. Use the below formula to find the population.
Population in 2100 = Population of 2020 (1 + growth rate)^n
Population in 2100 = 7.8 (1 + 0.0105)^80
Population in 2100 = 17.99 billions.
Now, find the growth rate in 2100.
dN/dt = [r N (K – N) ] / K
r = Malthusian parameter
K = carrying capacity.
Now divide both sides by K, now x = N/K then do the differential equation.
dx/dt = r x ( 1- x)
Now integrate, x(t) = 1/ [ 1 + (1/x – 1) c^-rt
From the first equation = dN/dt = (13 – 7.8) / 80 = (r × 7.8×(13 – 7.8) / 12
0.065 = (r × 7.8× 5.2) / 12
0.065 = r × 3.38
r = 1.92%
The amount of time a passenger waits at an airport check-in counter is random variable with mean 10 minutes and standard deviation of 2 minutes. Suppose a random sample of 50 customers is observed. Calculate the probability that the average waiting time waiting in line for this sample is (a) less than 10 minutes (b) between 5 and 10 minutes
Answer:
(a) less than 10 minutes
= 0.5
(b) between 5 and 10 minutes
= 0.5
Step-by-step explanation:
We solve the above question using z score formula. We given a random number of samples, z score formula :
z-score is z = (x-μ)/ Standard error where
x is the raw score
μ is the population mean
Standard error : σ/√n
σ is the population standard deviation
n = number of samples
(a) less than 10 minutes
x = 10 μ = 10, σ = 2 n = 50
z = 10 - 10/2/√50
z = 0 / 0.2828427125
z = 0
Using the z table to find the probability
P(z ≤ 0) = P(z < 0) = P(x = 10)
= 0.5
Therefore, the probability that the average waiting time waiting in line for this sample is less than 10 minutes = 0.5
(b) between 5 and 10 minutes
i) For 5 minutes
x = 5 μ = 10, σ = 2 n = 50
z = 5 - 10/2/√50
z = -5 / 0.2828427125
= -17.67767
P-value from Z-Table:
P(x<5) = 0
Using the z table to find the probability
P(z ≤ 0) = P(z = -17.67767) = P(x = 5)
= 0
ii) For 10 minutes
x = 10 μ = 10, σ = 2 n = 50
z = 10 - 10/2/√50
z = 0 / 0.2828427125
z = 0
Using the z table to find the probability
P(z ≤ 0) = P(z < 0) = P(x = 10)
= 0.5
Hence, the probability that the average waiting time waiting in line for this sample is between 5 and 10 minutes is
P(x = 10) - P(x = 5)
= 0.5 - 0
= 0.5

Closeness of a measurement to the actual value of the dimension being measured. For example, a measurement of 1.99999 cm for an object that is 2 cm wide has a high level of accuracy? a.precision b.conversion factor c.quantify d.accuracy?
a. precision
b. conversion factor
c. quantify
d. accuracy
Answer:
d. accuracy
Step-by-step explanation:
In measurements, accuracy is a term that is used to describe the closeness of a measured value to the actual or true value. While precision describes how close different measured values are to each other.
Thus when a measured value is accurate, it implies that the value is very close or almost equal to the true value. The correct answer to the question is is option D.
Suppose that Wilma is considering purchasing a new car with a monthly loan payment of $395. Her current insurance provider quotes a fee of $105 per month, and the registration fee in her state is $165 per year. How much money would she need if she considers purchasing this car?
Answer:
135
Step-by-step explanation:
To answer this question you would write down 105+165 you'll get 260 then to know how much wilma will have to pay you would take the amount wilma pays monthly which is 395 and the answer you got from 105+165 which is 260 and add 395-260 so, 395-260=135
Answer: Wilma should also consider the expenses of fuel, maintenance, and repairs. These are variable expenses and can vary greatly from month to month. To make sure that she can afford a new car, she needs to include these variable expenses in her car budget calculations. If Wilma can’t afford these expenses, she may need to choose a different car with a lower monthly payment or one that requires fewer maintenance costs.

The measure of an angle is two times the measure of its complementary angle. What is the measure of each angle?
Answer:
30 and 60 degrees
Step-by-step explanation:
30 and 60 are complementary angles. 60 is two times the measure of its complementary angle, or 30. 60+30=90.
Complementary angles are angles that add up to 90 degrees.
Angle one = x
Angle two = 2x
2x + x = 90 degrees
Combine like terms.
3x = 90 degrees.
Divide both sides by 3
x = 30
Angle one = x = 30 degrees
Angle two = 2x = 2(30) = 60 degrees.
