The measure of x in the intersected chord is 16.

If two chords intersect in a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Using the chord intersection angle theorem,

5x - 7  = 1 / 2 (119 + 27)

5x - 7 = 1 / 2 (146)

5x - 7 = 73

add 7 to both sides of the equation

5x - 7 = 73

5x - 7 + 7 = 73 + 7

5x = 80

divide both sides of the equation by  5

A.  The number of shortest lattice paths from (2, 2) to (11, 11) that pass through (8, 10) is 28 * 4 = 112.

B. The number of shortest lattice paths from (2, 2) to (11, 11) that avoid (8, 10) is the total number of paths minus the number of paths that pass through (8, 10), which is 48620 - 112 = 48508.

What is combinatorics?

Combinatorics is a branch of mathematics that deals with counting and arranging the possible outcomes of different arrangements and selections of objects.

For part (a), the number of shortest lattice paths from (2, 2) to (11, 11) that pass through (8, 10) is given by the product of the number of shortest lattice paths from (2, 2) to (8, 10) and from (8, 10) to (11, 11).

To find the number of shortest lattice paths from (2, 2) to (8, 10), we can count the number of ways to choose 6 steps up out of 8 total steps (the remaining 2 steps are to the right), which is 8 choose 6 = 28.

Similarly, the number of shortest lattice paths from (8, 10) to (11, 11) is the number of ways to choose 1 step up out of 4 total steps (the remaining 3 steps are to the right), which is 4 choose 1 = 4.

Therefore, the number of shortest lattice paths from (2, 2) to (11, 11) that pass through (8, 10) is 28 * 4 = 112.

b) To find the number of shortest lattice paths from (2, 2) to (11, 11) that avoid (8, 10), we can use the principle of inclusion-exclusion.

Let's first count the number of shortest lattice paths from (2, 2) to (11, 11) without any restrictions. Since we can only move up or to the right, the number of such paths is the number of ways to choose 9 steps up out of 18 total steps (the remaining 9 steps are to the right), which is 18 choose 9 = 48620.

Next, we count the number of shortest lattice paths from (2, 2) to (11, 11) that pass through (8, 10). Using the method described in part (a), we found that the number of such paths is 28 * 4 = 112.

Therefore, the number of shortest lattice paths from (2, 2) to (11, 11) that avoid (8, 10) is the total number of paths minus the number of paths that pass through (8, 10), which is 48620 - 112 = 48508.

The red tractor is heavier.

To determine which tractor is heavier, Mr. Vega needs to compare the weights of the blue and red tractors. The blue tractor weighs [tex]\frac{3}{5}[/tex] of a ton, and the red tractor weighs [tex]\frac{4}{6}[/tex] of a ton.

First, we need to simplify the fractions if possible. In this case, we can simplify the red tractor's fraction by dividing both the numerator and denominator by 2:
[tex]\frac{4}{6} = \frac{\frac{4}{2} }{\frac{6}{2} } = \frac{2}{3}[/tex]

Now we can compare the simplified fractions:
[tex]Blue tractor: \frac{3}{5}[/tex]
[tex]Red tractor: \frac{2}{3}[/tex]

To compare these fractions, we can find a common denominator. The least common multiple of 5 and 3 is 15. To convert the fractions to the same denominator, we multiply the numerators and denominators by the necessary factors:

[tex]Red tractor: (\frac{2}{3}) (\frac{5}{5}) = \frac{10}{15}[/tex]

[tex]Blue tractor: (\frac{3}{5}) (\frac{3}{3}) = \frac{9}{15}[/tex]

Now we can easily compare the weights:
[tex]Blue tractor: \frac{9}{15}[/tex]

[tex]Red tractor: \frac{10}{15}[/tex]


Since [tex]\frac{10}{15}[/tex] is greater than [tex]\frac{9}{15}[/tex] , the red tractor is heavier.

To find the maximum number of vans needed to ferry 80 people using the given terms, let's set up an inequality. Let's use the variable "v" to represent the number of vans.

Since a van can ferry a maximum of 12 people, we can write the inequality as:

12v ≥ 80

Now, let's solve for "v":

Divide both sides of the inequality by 12.
v ≥ 80/12

Simplify the inequality.
v ≥ 6.67

Answer:

10.24 gallons

$276.48

Step-by-step explanation:

The area of the wall can be calculated by multiplying the length and height of the wall:

Area of wall = length x height = 32 x 16 = 512 square feet

To calculate the number of gallons of paint needed, we need to divide the area of the wall by the coverage of one gallon of paint:

Number of gallons of paint = Area of wall / Coverage of one gallon of paint

Number of gallons of paint = 512 / 50

Number of gallons of paint = 10.24

Therefore, it will take approximately 10.24 gallons of paint to paint the wall.

To calculate the cost of the paint, we need to multiply the number of gallons of paint by the cost per gallon:

Cost of paint = Number of gallons of paint x Cost per gallon

Cost of paint = 10.24 x $27

Cost of paint = $276.48

Therefore, it will cost $276.48 to paint the wall.

0.135 or 13.5%  is the probability that he had 3 âhits

The probability that the player had 3 hits in 5 at-bats can be calculated using the binomial probability formula, which is:

P(x) = (nCx) * p^x * (1-p)^(n-x)

where:
- P(x) is the probability of getting x hits
- n is the number of at-bats (in this case, 5)
- x is the number of hits we want to find the probability for (in this case, 3)
- p is the probability of getting a hit in one at-bat (in this case, 0.343)
- (1-p) is the probability of not getting a hit in one at-bat (in this case, 0.657)

Plugging in the values, we get:

P(3) = (5C3) * 0.343^3 * 0.657^(5-3)
P(3) = (10) * 0.039304527 * 0.4305961

We need to make some assumptions. Let's assume that the survey allowed students to choose one favorite hobby and that bike riding was one of the options.

We also need to know the percentage of students who chose bike riding as their favorite hobby. If this information is not given, we cannot accurately estimate the number of students who would say that bike riding is their favorite hobby.

Suppose that 30% of the surveyed students chose bike riding as their favorite hobby. To find out how many students this represents, we can use the following formula:

Expected number of students = Percentage of students x Total number of students surveyed

Plugging in the values we have, we get:

Expected number of students who say bike riding is their favorite hobby = 0.30 x 60 = 18

Therefore, we can expect that approximately 18 of the 60 seventh-grade students surveyed would say that bike riding is their favorite hobby, based on the assumption that 30% of the students chose this option.

Answer:

Step-by-step explanation:

PV = $1200

i = 5%

Simple interest formula:

FV = PV (1 + i × n)

FV = 1200 (1 + 5% x 8)

FV = $1680

The integral of f(x, y) = x + y over the given curve is 8.

To integrate the function f(x, y) = x + y over the curve C: x² + y² = 4 in the first quadrant from (2, 0) to (0, 2), we will use the line integral. Since the curve is a circle, we can parameterize it using polar coordinates as follows:

x = 2cos(θ)
y = 2sin(θ)

Now, let's find the derivatives:

dx/dθ = -2sin(θ)
dy/dθ = 2cos(θ)

Next, we substitute x and y in f(x, y):

f(x, y) = 2cos(θ) + 2sin(θ)

Now, we can set up the line integral:

∫[f(x, y) * ||dr/dθ||]dθ

Since ||dr/dθ|| = sqrt((-2sin(θ))^2 + (2cos(θ))^2) = 2, the line integral becomes:

∫[2cos(θ) + 2sin(θ)] * 2 dθ

To find the limits of integration, we can use the points (2, 0) and (0, 2). In polar coordinates, these points correspond to θ = 0 and θ = π/2.

So, the line integral becomes:

∫[4cos(θ) + 4sin(θ)]dθ from 0 to π/2

Now, we can integrate and evaluate:

[4sin(θ) - 4cos(θ)] from 0 to π/2 = [4(1) - 4(0)] - [4(0) - 4(1)] = 8

Thus, the integral of f(x, y) = x + y over the given curve is 8.

r = √[tex]((0 - 0)^2[/tex] + (√[tex]38 - 0)^2)[/tex] = √38

Now that we know the radius of the circle is √38, we can determine where the point N(-5,-3) lies relative to the circle. We can find the distance between N and the center of the circle:

d = √[tex]((-5 - 0)^2[/tex] + [tex](-3 - 0)^2)[/tex] = √34

Since the distance between N and the center of the circle is less than the radius of the circle, the point N is inside the circle. Therefore, N lies inside the circle centered at C(0,0) with radius √38.

Step-by-step explanation:

The statement''El 91 no es un número primo porque tiene más divisores que el 1 y el 91''  is true because  91 is not a prime number.

A prime number is a positive integer that has only two divisors, 1 and itself. To check if 91 is a prime number, we need to find its divisors. We can start by dividing 91 by 2, but we find that 2 is not a divisor of 91. Next, we can try dividing it by 3, and we get 30 with a remainder of 1. This means that 3 is not a divisor of 91 either.

We continue dividing by 4, 5, 6, and so on until we reach 13, which gives us 7 as a quotient and 0 as a remainder. Therefore, the divisors of 91 are 1, 7, 13, and 91, which means that 91 is not a prime number because it has more than two divisors. Hence, the statement is true.

91 ÷ 2 = 45 r 1

91 ÷ 3 = 30 r 1

91 ÷ 4 = 22 r 3

91 ÷ 5 = 18 r 1

91 ÷ 6 = 15 r 1

91 ÷ 7 = 13 r 0

Since 91 has more than two divisors, it is not a prime number.

The farmer should construct a rectangle that is twice as long as it is wide, with dimensions of 1216.56 m x 608.28 m, and should use 7301.36 m of fence to divide it in half parallel to the shorter side in order to minimize the cost of the fence.

To minimize the cost of the fence, the farmer should construct a rectangle that is twice as long as it is wide, with the dividing fence parallel to the shorter side. This will result in two identical rectangles each with an area of 375 000 m².

The perimeter of the rectangle can be calculated as follows:

P = 2L + 2W

where L is the length and W is the width.

Since the area of the rectangle is 750 000 m² and the length is twice the width, we can write:

L x W = 750 000

L = 2W

Substituting L = 2W into the equation for area, we get:

2W x W = 750 000

2W² = 750 000

W² = 375 000

W = 608.28 m

L = 2W = 1216.56 m

So the dimensions of the rectangle are 1216.56 m x 608.28 m.

The perimeter of each rectangle is:

P = 2L + 2W

P = 2(1216.56) + 2(608.28)

P = 3650.68 m
