Which of the following graph represents a functional relationship between a and y?

The quantity of positive numbers smaller than or equal to [tex]$10,000$[/tex] is [tex]$\fbox{958}$[/tex].

We see that a number [tex]$n$[/tex] is [tex]$p$[/tex]-safe if and only if the leftovers from[tex]$n\mod p$[/tex] is greater than [tex]$2$[/tex] and less than [tex]$p-2$[/tex]; thus, there are [tex]$p-5$[/tex] residues [tex]$\mod p$[/tex] that a [tex]$p$[/tex]-safe number can have. Therefore, a number [tex]$n$[/tex] satisfying the circumstances of the issue may [tex]$2$[/tex] different residues [tex]$\mod 7$[/tex], [tex]$6$[/tex] different residues [tex]$\mod 11$[/tex], and [tex]$8$[/tex] different residues [tex]$\mod 13$[/tex]. According to the Chinese Remainder Theorem, for a number [tex]$x$[/tex] that is [tex]$a$[/tex] (mod b) [tex]$c$[/tex] (mod d) [tex]$e$[/tex] (mod f) has one solution if [tex]$gcd(b,d,f)=1$[/tex]. For instance, in this instance, the number [tex]$n$[/tex] can be: [tex]3 (mod 7) 3 (mod 11) 7 (mod 13)[/tex]so since [tex]$gcd(7,11,13)=1$[/tex], there is [tex]1[/tex] solution for [tex]n[/tex] for this case of residues of [tex]$n$[/tex]. As a result, according to the Chinese Remainder Theorem, [tex]$n$[/tex] can have [tex]$2\cdot 6 \cdot 8 = 96$[/tex] different residues mod [tex]$7 \cdot 11 \cdot 13 = 1001$[/tex]. Thus, there are [tex]$960$[/tex] values of [tex]$n$[/tex] satisfying the conditions in the range [tex]$0 < n \le 10010$[/tex]. Nevertheless, we now have to eliminate all values bigger than [tex]$10000$[/tex] that satisfy the conditions. We can simply see by looking at residues that the only suitable values are [tex]$10006$[/tex] and [tex]$10007$[/tex], so there remain [tex]$\fbox{958}$[/tex] values satisfying the conditions of the problem.

Answer:

16 19/50

Step-by-step explanation:

first make improper fractions of both 3 9/10 and 4 1/5

mutltiply the denomiator (the number on the bottom) by the whole number, add the numerator (the number on the top) and put that number over the denomiator. 3 9/10 = 39/10 and 4 1/5 = 21/5. Multiply the improper fractions. numerator x numerator and write that on the top with a line under it. Multiply the denomiators and write that on the bottom. 39*21= 819. 10*5=50. your number would be 819/50. Then divide 819 by 50. You get 16 19/50

The required cost of the meal given as a hot dog is of $6 and the hamburger is of $8.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Let's call the cost of a hot dog meal "x" and the cost of a hamburger meal "y".

From Mrs. Hammond's purchase, we know that:

x + 3y = 30   -- - - - - -(1)

From Mr. Weber's purchase, we know that:

3x + 3y = 42 - - - - - -(2)

We can use substitution to solve for one of the variables in terms of the other. If we substitute the first equation into the second equation:

3x + 3y = 42

3x + 3(30 - x)/3 = 42

3x + 30 - x = 42

2x = 12
x = 6

now,
6 + 3y = 30
3y = 24
y = 8

Thus, the required cost of the meal given as a hot dog is of $6 and a hamburger is $8.

If one side and two angles of a triangle are known, the triangle can be solved Law of Sines.

If A, B, and C are the measurements of the angles of a triangle, and a, b and c are the lengths of the sides opposite of the corresponding angles, then the ratio of side length to the sine of the opposite angle must all be the same.

                                      a/SinA = b/SinB = c/SinC

So, let's say that the value of 'a' is given and the value of angles A and B are also given. By using the law of sine, we can determine the value of 'b' as follows:

                                      a/SinA = b/SinB

                                      b = (a/SinA) SinB

Let the number of nickels that Logan gave out be = n , and

the number of dimes that Logan gave out be =  d ;

From the information , we know that Logan gave out 50% more nickels than dimes,

that means ; n = d + 0.5d = 1.5d   ...equation(1) ;

We also know that the total amount given out in nickels and dimes is $6.65, and each nickel is worth of  $0.05 and each dime is worth of  $0.10,

So ,  n×0.05 + d×0.10 = 6.65 ;

Substituting the expression for n from the first equation into the second:

⇒ (1.5d)×0.05 + d×0.10 = 6.65 ;

Expanding and solving for d ;

we get ;

⇒ 0.075d + 0.10d = 6.65 ;

⇒ 0.175d = 6.65 ;

Based on the given estimate that the candidate will receive 45% of the votes and the margin of error being 4%, the most appropriate conclusion would be option C:

The candidate will receive between 45% and 49% of the votes. To understand why this is the most appropriate conclusion, we need to consider the concept of margin of error. The margin of error is a measure of the uncertainty in the estimate and represents the range within which the true value is likely to fall. In this case, we have an estimated proportion of votes (45%) and a margin of error (4%).

To calculate the range within which the true value is likely to fall, we add and subtract the margin of error from the estimated proportion. Upper bound: [tex]45 + (4 of 45) = 45 + 1.8% = 46.8[/tex]  

Lower bound: [tex]45 - (4 of 45) = 45 - 1.8 = 43.2[/tex] %

Therefore, we can conclude that the candidate is likely to receive between 43.2% and 46.8% of the votes. Option C, which states that the candidate will receive between 45% and 49% of the votes, aligns with this conclusion. Option B (between 41% and 45%) is too conservative as it does not account for the upper bound of the margin of error,

The volume of the solid is approximately 807.08 cubic units.

To determine the volume of the solid, we can use the method of cylindrical shells.

Imagine taking a slice of the solid parallel to the base, with the cross-sectional area being a square of side length x (where x is a function of the height). The volume of this slice is the product of the square area and the height. The height of the slice is equal to the difference in the radii of two consecutive circular cross sections.

The radius of the larger circular cross-section can be found using the Pythagorean theorem, which states that the square of the hypotenuse (the radius) is equal to the sum of the squares of the other two sides (the height and half the side length of the square). Thus, we have:

r² = x² + (15-x)²

Solving for x, we get:

x = 15 * √(1 - (r/15)²)

The volume of the slice is then given by:

V = x² * (15 - x)

To find the total volume of the solid, we integrate this expression with respect to r from 0 to 15. The result is approximately 807.08 cubic units.

The point that creates a right triangle with the points (3, 6) and (8, -2), which Christopher could place on the graph to create a right triangle is the point (8, 7.25)

A right triangle is a triangle with one ninety degrees (90°) interior angle.

The points on the right triangle Christopher already graphed (3, 6), and (8, -2)

The property of a right triangle is one of the interior angles is 90°, therefore, the legs or two of the sides of a right triangle are perpendicular.

The slope of the line joining the specified two points is found as follows;

Slope = (-2 - 6)/(8 - 3) = -8/5

The slope of the line perpendicular to the line segment Christopher used to join the points (3, 6), and (8, -6) is 5/8

The equation of the perpendicular line is therefore;

y - 6 = (5/8)·(x - 6)

y = (5/8)·(x - 6) + 6 = 5·x/8 + 18/8

y = 5·x/8 + 18/8

When x = 8, we get; y = 5 × 8/8 + 18/8 = 7.25

Working alone, Allen can build 1/8 of the fence in 1 hour and working together, Allen and Danny can build 1/X of the fence in 1 hour, where X is their combined rate.

Let's say the total time required to build the fence is T hours.

After 2 hours, Allen has completed 1/8 * 2 = 1/4 of the fence.

So, the remaining work to be done is T - 1/4.

When Allen and Danny work together, their combined rate is X = 1 / (1/8 + 1/16) = 4/7.

The total time taken by them to finish the remaining work is (T - 1/4) / (4/7) = (7/4) * (T - 1/4) = 7T/28 - 7/28.

So, the total time taken to build the fence is 2 + (7T/28 - 7/28) = 2 + 7T/28 = T.
