suppose 1,608 of 2,400 registered voters sampled said they planned to vote for the republican candidate for president. using the 0.95 degree of confidence, what is the interval estimate for the population proportion (to the nearest 10th of a percent)?
Using the concepts of confidence interval, we got that is he interval estimate for the population proportion if we suppose 1,608 of 2,400 registered voters sampled said they planned to vote for the republican candidate for president.
We know that population proportion is given by the fraction of number of positive results to the total number of results
Therefore, Population Control(P)=1608/2400
=>P =0.67
Now, we are given that confidence interval is 0.95 degree or 95%
For 95%,confidence interval is given by =P±√[P×(1-P)]/n
where n is the total number of registered voters, and P is the population control.
confidence interval=0.67±√[0.67×(1-0.67)]/2400
=0.67±√(0.67×0.33)/2400
=0.67±√0.2211/2400
=0.67±(0.47/48.98)
=0.67±0.0095
=0.660 and 0.679
Hence, if we suppose 1,608 of 2,400 registered voters sampled said they planned to vote for the republican candidate for president. using the 0.95 degree of confidence, the interval estimate for the population proportion is (0.660,0.679)

one of euler's conjectures was disproved in the 1960s by three american mathematicians when they showed that there is a positive integer such that find the value of .
It quickly becomes apparent that 174 is much too large, so n must be 144.The value of the n is 144.
Taking the given equation modulo 2,3, and 5, respectively, we have
n⁵≡(mod 2)
n⁵≡(mod 3)
n⁵≡( mod 5)
By either Fermat's Little Theorem (FLT) or inspection, we get

n≡(mod 3)
n≡( mod 5)
By either the Chinese Remainder Theorem (CRT) or inspection, we get n≡ 24 ( mod 30)
It is clear that n>133, so the possible values for n are 144,174,204,...Note that
n⁵ = 133⁵ + 110⁵ + 84⁵ + 27⁵
n⁵ < 133⁵ + 110⁵ +( 84 + 27)⁵
n⁵ =133⁵ + 110⁵ + 111⁵
n⁵ < 3.133⁵
From which (n/133)⁵ < 3
If n>= 174 then,
(n/133)⁵ > 1.3⁵
(n/133)⁵ = 3

the product of two consecutive nonnegative integers is 240 find the integers and separate them with a comma
The product of two consecutive non-negative integers is 240 and the integers are 15,16.
What are consecutive integers?
The numbers that come after one another are known as consecutive integers. They proceed sequentially or alphabetically. For instance, a group of natural numbers is a sequence of integers. In mathematics, the term "consecutive" refers to an uninterrupted succession or a continuous flow of numbers, so that successive integers follow a sequence in which each succeeding number is one more than the one before it. The mean and median in an array of successive integers (or in numbers) are both identical. In the event that x is an integer, then x + 1 and x + 2 are also integers.Let the numbers be x, x+1
Product is x(x+1)=240
x² + x = 240
x² + x − 240 = 0
x² + 16x − 15x − 240 = 0
x(x+16) − 15(x+16) = 0
(x+16)(x−15)=0
x = 15,−16

The force of attraction is 2.78 Newton when m = 2 kilograms and d = 15 meters.
According to the question,
We have the following information:
The force of attraction, F of a body varies directly as its mass (m) and inversely as the square of the distance (d) from the body. And when m=8kg and d=5meters then F=100 Newtons.
Now, let's take the constant for this case to be k.
We have the following expression:
F = km/[tex]d^{2}[/tex]
Putting the values in this expression to find the value of k:
100 = 8k/(5*5)
Using the cross multiplication method:
2500 = 8k
k = 2500/8
k = 312.5
Now, we have the following value of F:
F = 312.5*2/15*15
F = 625/225
F = 2.78 Newton
Hence, the force of attraction is 2.78 Newton when m = 2 kilograms and d = 15 meters.

how many ordered pairs ( m , n ) of positive integers, such that m > n , have the property that their squares differ by 96 ?
Answer:
4 pairs
Step-by-step explanation:
You want the number of pairs of integers (m, n) such that m > n and m² -n² = 96.
Difference of squaresThe difference of squares is factored as ...
m² -n² = (m -n)(m +n)
In order for the difference to be 96, these factors must be factors of 96.
Factors of 96The prime factorization of 96 is ...
96 = 2^5 · 3
The number of divisors of 96 is the product of the exponents of these factors, each increased by 1:
(5+1)(1+1) = 12
That is, there are 12/2 = 6 factor pairs ab such that a<b. They are ...
96 = 1·96 = 2·48 = 3·32 = 4·24 = 6·16 = 8·12
SolutionThe values of m and n relate to the values of 'a' and 'b' by ...
m = (a+b)/2
n = (b-a)/2
In order for m and n to be integers, the values of 'a' and 'b' must both have the same parity. That is, they must both be even, or both be odd. This eliminates the factor pairs 1·96 and 3·32, leaving 4 (a, b) pairs, hence 4 (m, n) pairs. Possible ordered pairs are ...
(m, n) ∈ {(25, 23), (14, 10), (11, 5), (10, 2)} . . . . . 4 pairs
Two sides of a triangle are 30in and 30in, what are the possible lengths of the third side
Answer:
[tex]0 < x < 60[/tex]
Step-by-step explanation:
By the Triangle Inequality Theorem:
30 + 30 > x, so 60 > x ----> x < 60
30 + x > 30, so x > 0
x + 30 > 30, so x > 0
Putting these inequalities together, we have 0 < x < 60. So the length of the third side can be greater than 0 inches but less than 60 inches.

Hey, so because you didn't include the image this is impossible to get the number values. But, essentially you'd solve it something like this.
Remember, the Y axis goes up, and its located when you are at X = 0.
The y intercept is the value of Y, when is 0.
The slope of a line is referred to as "rise/run"
Basically, you take any given spot. For example, from x = 0 to x = 2. The run is 2, because thats how much x value the line covers. So, in that "run" how much do you go up or go down? Lets say in those 2 x's that you travelled, how much did the height change? If you changed by going up 4 units, it would be (rise/run) 4/2 = 2. The slope would be 2. That means that for every time x increases by 1, Y goes up 2.
