The decimal representation of 1/70000000 is 0.0000000142857142857....
In math, what is a fraction?
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
To find the digit that occurs in the 2023rd place after the decimal point, we can use long division to divide 1 by 70000000 and track the remainders.
Since the decimal representation of 1/70000000 is repeating every 6 digits, we can find the digit at the 2023rd place by taking the remainder when 2023 is divided by 6.
2023 % 6 = 1
So the digit in the 2023 place is the first digit after the repeating decimal, which is 4.
Therefore the digit in the 2023rd place after the decimal point is 4.

If ‘a’ varies jointly with ‘b’ and ‘c’, and inversely as the square of ‘d’, how would ‘a’ be affected if ‘b’ is tripled and both ‘c’ and ‘d’ are doubled.
When two or more variables vary jointly, their product is always constant. In this case, if 'a' varies jointly with 'b' and 'c' it means that their product is always constant, so abc = k, where k is a constant value.
When a variable 'a' varies inversely as the square of another variable 'd', it means that a*1/d^2 = k, where k is a constant value.
So, if 'b' is tripled, 'c' is doubled and 'd' is doubled, we can see the effect on 'a' by substituting the new values into the equations.
abc = k => a3b2c = k
a1/d^2 = k => a1/(2d)^2 = k
So the effect on 'a' if 'b' is tripled, 'c' is doubled, and 'd' is doubled is that it will be divided by 4.
a3b2c = a1/(2d)^2 => a = k / (3b2c*(2d)^2) = (k/(12bcd^2))
So a = k/(12bcd^2) = a/4.
Therefore, the value of 'a' is decreased by a factor of 4.

A car travels 19 mph slower in a bad rain storm than in sunny weather. The car travels the same distance in 2 hr in sunny weather as it does in 3 hr in rainy weather.
Find the speed of the car in sunny weather.
It is in good conditions, the automobile travels at 57 mph.
Explain about the distance?Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.
A scalar quantity known as distance measures "how much ground an object has traversed" while moving. The term "how far out of place an object is" is referred to by the vector quantity displacement, which is the object's overall change in position.
Simply draw a vector from your initial position to your destination and solve for the length of this line to determine displacement. In the case of a circular 5K path, where your beginning and ending positions are identical, your displacement is 0. Displacement in physics is denoted by s.
"A automobile moves 20 mph more slowly in heavy rain than in bright sunshine."
x - 19 = y
where "x" stands for speed in good weather and "y" stands for speed in bad weather.
"The same distance is covered by the car in two hours in the sun as it is in three hours in the rain."
2x = 3y
where "x" stands for speed in good weather and "y" stands for speed in bad weather.
The speed of the car in good weather, or "x," is what we are looking for. In the second equation, substitute the first equation's value for the variable "y."
x - 19 = y
2x = 3y
2x = 3 (x - 19)
Distribute:
2x = 3x - 57
3x off on both sides equals:
-x = -57
Give both sides a -1:
x = 57

A student decides to finance a used car over a 5-yr (60-month) period. After making a down
payment of $2000, the remaining cost of the car including tax and interest is $14,820. The
amount owed y = A(t) (in $) is given by A(t) = 14,820-247t, where t is the number of
months after purchase and 0 ≤t≤ 60. Determine the t-intercept and y-intercept and interpret
their meanings in context.
Answer:The t-intercept of a function is the point at which the function crosses the t-axis. To find the t-intercept of the function A(t) = 14,820 - 247t, we need to find the value of t when A(t) = 0. Setting A(t) = 0 and solving for t, we get:
14,820 - 247t = 0
t = (14820/247)
The t-intercept of the function is 60 months, which means that after 60 months (or 5 years) the amount owed on the car will be $0.
The y-interval of a function is the point at which the function crosses the y-axis. To find the y-intercept of the function A(t) = 14,820 - 247t, we need to find the value of A(t) when t = 0.
At t = 0, A(t) = 14,820 - 247(0) = 14,820.
The y-intercept of the function is $14,820 which means that before making the first payment, the cost of the car including tax and interest is $14,820.

Evaluate the convolution integral (h*f)(t) , and compare the resulting function with the solution obtained in part (a): (h*f)(t) = ∫ dw =
The result of the convolution integral is the same as the solution obtained in part (a).
a. Solving the ODE with y(0) = 0 using integrating factors,
multiplying both sides of the equation by e^4t, we get
e^4t y' + 4e^4t y = 4e^-te^4t
Integrating both sides,
∫ (e^4t y' + 4e^4t y) dt = ∫ 4e^-te^4t dt
Therefore,
e^4t y = ∫ 4e^-te^4t dt + C
Since y(0) = 0, C = 0,
y = 1/4 ∫ 4e^-te^4t dt
Using integration by parts,
y = 1/4 [te^-t + 4/3 e^-t]
Therefore,
y(t) = 1/4 [te^-t + 4/3 e^-t]
b. The transfer function of the system is given by
H(s) = Y(s)/F(s) = 1/4s/(s+4)
c. The impulse response of the system is given by
h(t) = L^-1[H(s)] = 1/4e^-t
d. The convolution integral (h*f)(t) can be evaluated as follows,
(h*f)(t) = ∫ h(t-w)f(w)dw
= ∫ 1/4e^-(t-w) 4e^-w dw
= 1/4 ∫ 4e^-(t+w) dw

P′ is equal to x / n, where x is the total number of successes and n is the sample size. As a point estimate for the genuine population proportion, the variable p′ represents the sample proportion.
FPC = (N-n)/(N-1), where Z/2 is the critical value of the Normal distribution at /2, p is the sample proportion, n is the sample size, and N is the size of the population (for example, at a confidence level of 95%, is 0.05 and the critical value is 1.96).
A portion of a population that possesses a certain characteristic, given as a percentage, fraction, or decimal of the entire population. The population percentage for a finite population is equal to the population's size divided by the proportion of its members who possess a given attribute.
Given data :
p = 60 / 300 = 0.2
q = 1 - p = 0.8
mean proportion = p = .2
standard error = sqrt(p * (1-p / 300) = sqrt(0.2 * 0.8/ 300) =0.00053333333

If mathematics departments had 10 million recent graduates, what is the chance that the sample will consist of two graduates who intend to teach high school? c. Are the selections technically independent in part a? Are they technically independent in part b? In which part can you assume independence anyway? Why?
In part a, since the population mean is small, selections are independent and can be assumed to be so. In part b, the population size is too large for selections to be independent, so independence can not be assumed.
a. If mathematics departments had only four recent graduates total, the chance that the sample will consist of two graduates who intend to teach high school is
0.5 * 0.5
= 0.25.
b. If mathematics departments had 10 million recent graduates, the chance that the sample will consist of two graduates who intend to teach high school is
0.5 * 0.5
= 0.25.
c. The selections are technically independent in part a, since the population size is small enough that the selection of one person will not affect the probability of selecting the other person. The selections are not technically independent in part b, since the population size is so large that selecting one person affects the probability of selecting the other person. In part a, you can assume independence since the population size is small enough that it is reasonable to assume that the selections are independent. In part b, you cannot assume independence since the population size is too large to make this assumption.

12. Hydrology A reservoir has a capacity of 9000 cu ft. How long will it take
to fill the reservoir at the rate of 250 gallons per minute?
It will take approximately 270.28 minutes, or 4 hours and 30.28 minutes, to fill the reservoir at a rate of 250 gallons per minute.
How to calculate the time it takes to fill a reservoir?we can use the formula:
time = volume ÷ flow rate
where volume is the capacity of the reservoir in cubic feet and flow rate is the rate at which the reservoir is filled in cubic feet per minute.
Since the capacity of the reservoir is given in cubic feet and the flow rate is given in gallons per minute, we need to convert the flow rate to cubic feet per minute. One gallon is equal to 0.133681 cubic feet, so:
250 gallons/minute x 0.133681 cubic feet/gallon = 33.342 cubic feet/minute
So the flow rate in cubic feet per minute is 33.342. Now we can calculate the time it takes to fill the reservoir:
time = 9000 cubic feet ÷ 33.342 cubic feet/minute = 270.28 minutes
So it will take approximately 270.28 minutes, or 4 hours and 30.28 minutes, to fill the reservoir at a rate of 250 gallons per minute.

The measure of ∠ADB is equivalent to 90°.
What is geometry?Geometry is a branch of mathematics that deals with shapes, sizes, angles, and dimensions of objects.
Given is a geometrical image as shown.
We can write -
∠ADC = ∠ADB + ∠BDC
(- 3c + 120°) + (- 10 c + 145°) = 135°
- 3c + 120° - 10c + 145° = 135°
- 13c + 265° = 135°
265° - 135° = 13c
13c = 130
c = 10
Now -
∠ADB = (- 3c + 120) = 90°
∠ADB = 90°
Therefore, the measure of ∠ADB is equivalent to 90°.

When you take samples from a population and compute a proportion from each one, you can consider the distribution of those proportions. This is called the sampling distribution for the population proportion.The Central Limit Theorem tells us that the sampling distribution for the population proportion is a) skewed left b) skewed right c) approximately normal d) uniform with the a) true population standard deviation b) true population proportion c) true population mean as its a)standard deviation b) mean c) proportion .
The sampling distribution is approximately normal.
What is the standard deviation?
Standard Deviation is calculated by first squaring the differences between the observations and the mean and then taking the square root of the sum of the squares of the differences divided by the number of observations - 1.
The Central Limit Theorem tells us that the sampling distribution for the population proportion is approximately normal.
The mean of the sampling distribution is equal to the true population proportion and the standard deviation of the sampling distribution is equal to the true population proportion times (1 - true population proportion) divided by the sample size.
So, the sampling distribution is approximately normal, with the true population proportion as its mean and the true population proportion times (1 - true population proportion) divided by the sample size as its standard deviation.
Hence, the sampling distribution is approximately normal.
