Answer:

Step-by-step explanation:

Opposite angles of a parallelogram are congruent.

Adjacent angles equal 180°.

If one angle is 36 ° more than the other than they are supplementary or equal to 180°.

x + x + 36 = 180

2x + 36 = 180

2x + 36 - 36 = 180 -36

2x = 144

2x/2 = 144/2

x = 72

2 angles = 72°

2 angles = 108°

All the angles = 360°.

72 × 2 = 144

108 x 2 = 216

144 + 216 = 360°

So this is correct.

The second wheel has a smaller circumference compared to the first wheel. The second wheel completes a revolution when the wheel turns 75.40 inches, but the odometer reads 84.82 inches.

There are two types of odometers

In the case of a mechanical odometer, the worm gear is used to make the gear train, and the overall gear ratio is 1690:1, which means that when the vehicle travels a distance of 1 mile, the mechanical odometer input shaft makes 1690 revolutions during this time. In the case of a digital odometer, a magnetic sensor is used to receive pulses, each of which counts as one revolution. We now have a bicycle odometer designed for 27 wheels. Thus, d₁ = 27 inches is the diameter of the first wheel

d₂= 24 inches is the diameter of the second wheel

The odometer is the distance traveled by the vehicle, given as the number of revolutions of the wheel multiplied by the circumference of the wheel. So for the first wheel, Therefore, in case of first

wheel, [tex]C_1 = πd_1 [/tex]

= π × 27

= 84.82 inches

In case of second wheel,

[tex]C_2 = π × d_2[/tex]

= π × 24 inches

= 75.40 inches

So, [tex]C_1 - C_2 = [/tex] 84.82 inches - 75.40 inches

= 9.42 inches

So we can see that the second wheel has circumference is less as compared to the first wheel.

The minimum number of states an equivalent NFA might have is n, while the maximum number of states is 2^n. However, while an NFA with 2^n states is always possible, it may not be the most efficient representation of the language recognized by the DFA.

The minimum number of states an equivalent NFA might have is n. This is because every DFA can be viewed as a special case of NFA, where each state has only one outgoing transition for each possible input symbol.

Therefore, we can create an equivalent NFA by simply replacing each transition of the DFA with a set of transitions, where the set contains all possible transitions that could be taken in that state for a given input symbol. This NFA will have n states, one for each state of the original DFA.

On the other hand, the maximum number of states an equivalent NFA might have is 2^n. This is because each state of an NFA can have multiple outgoing transitions for the same input symbol, leading to multiple possible paths through the automaton for a given input string.

Therefore, we can create an NFA with 2^n states by creating an NFA that has one state for each subset of the states of the original DFA. Each state in the new NFA represents a set of states from the original DFA that could be reached by following any sequence of transitions for a given input string.

It is worth noting that while an NFA with [tex]2^n[/tex] states can always be constructed to be equivalent to a given minimized DFA, it may not be the most efficient representation of the language recognized by the DFA. In practice, there are often more efficient ways of constructing equivalent NFAs with fewer states.

Answer:

The rectangle is 3.5 yd x 4 yd

Step-by-step explanation:

Area = length x width = lw

l = length = 2w - 3

w = width

Area = 14(2w - 3)(w) = 14

2w² - 3w - 14 = 0

Use quadratic equation to find the 2 roots of w:  a = 2, b = -3, c = -14

w = 3.5, -2     disregard the negative root

width = 3.5 yd

length = 2(3.5) - 3 = 4 yd

The dimensions of the rectangle are approximately 2.23 yards by 1.46 yards.

We are assuming the width of rectangle to be "x" yards. Then, the length would be (2x - 3) yards, since it is 3 yards less than double the width. The formula for the area of a rectangle is A = l x w, so we can plug in the values we know:

14 = (2x - 3) x x

Expanding the brackets:

14 = 2x² - 3x

Put this equation=0:

2x² - 3x - 14 = 0

Using the quadratic formula:

x = (3 ± √(3² + 4 x 2 x 14)) / (2 x 2)

x = (3 ± √97) / 4

We can ignore the negative root, since the width cannot be negative. Therefore,

x ≈ 2.23

This is the width of the rectangle. To find the length, we can plug this value back into the expression we derived earlier:

length = 2x - 3

length ≈ 1.46

Therefore, the dimensions of the rectangle are approximately 2.23 yards by 1.46 yards

The number of hours the student should record on the nighttime picture to complete a day-night cycle = 13 hours

The correct answer is an option (c)

We need to find the number of hours the student should record on the nighttime picture to complete a day-night cycle.

From the following pictures we can observe that, the sunrise time is 7:10 A.M. and the sunset timing is 6:10 P.M.

This means that thet daytime is of 11 hours (from 7:10 A.M. to 6:10 P.M.)

We know that the number hours in a day = 24

Let us assume that x represents the nighttime hours.

From this situation we get an equation,

x = 24 - 11

x = 13 hours

And the nighttime cycle would be:

from 6:10 P.M. to 7:10 A.M.

Therefore, the required number of hours = 13 hours

Find the complete question below.

The right option is: "Because angle 2 and angle 105 have equivalent angles, they must both be 75 degrees. As angles 1 and 2 are complementary, angle 1 must be 105°."

In geometry, a transversal is a line that crosses two or more parallel lines, whereas parallel lines are lines that never intersect. Eight angles are created when two parallel lines are crossed by a transversal; each pair of adjacent angle is congruent, as are alternate inner angles and alternate exterior angles.

We can infer from the facts provided that angle 2 and angle 105° are corresponding angles. A transversal that crosses two parallel lines and appears in the same relative position at each intersection creates corresponding angles. Angle 2 must be 75° if the 105° angle measures the same as the comparable angle.

We can use this knowledge to compute the measure of angle 1 since angles 1 and 2 are supplementary angles, which means they add up to 180°. Angle 1 must be 105° if angle 2 is 75° for the sum of the angles to reach 180°.

Answer: 54 in

Step-by-step explanation:

Since the altitude drawn from the vertex of the isosceles triangle forms two congruent right triangles and divides the base into two equal segments, we can work with one of the right triangles to find the length of the other side of the isosceles triangle.

Let's denote the length of the altitude as a, the length of half the base as b, and the length of the other side of the isosceles triangle as c. From the problem, we know that a = 18 inches and b = 15 inches / 2 = 7.5 inches.

We can use the Pythagorean theorem to find the length of c:

a² + b² = c²

Substitute the known values:

18² + 7.5² = c²

324 + 56.25 = c²

380.25 = c²

Now, take the square root of both sides to find the length of c:

c = √380.25

c ≈ 19.5 inches

Since the isosceles triangle has two sides with equal length, the perimeter is:

Perimeter = base + 2 * c

Perimeter = 15 + 2 * 19.5

Perimeter = 15 + 39

Perimeter = 54 inches

Thus, the perimeter of the isosceles triangle is approximately 54 inches.

Walter stored the remaining flour in 19 2 2/5-pound portions, with a small amount of flour left over.

we have:

(35/3) ÷ (12/5)

To divide by a fraction, we can multiply by its reciprocal:

(35/3) × (5/12)

Simplifying the fractions, we get:

(35/3) × (5/12) = (7/3) × (5/2) = 35/6

So, Walter stored the remaining flour in 35/6-pound portions. To express this in terms of 2 2/5-pound portions, we need to divide 35/6 by 2 2/5:

(35/6) ÷ (2 2/5)

Again, we convert 2 2/5 to an improper fraction:

2 × 5 + 2 = 12

So, we have:

(35/6) ÷ (12/5)

To divide by a fraction, we multiply by its reciprocal:

(35/6) × (5/12)

Simplifying the fractions, we get:

(35/6) × (5/12) = (35/72)

Therefore, Walter stored the remaining flour in 35/72 of a 2 2/5-pound portion.

To find the whole number of 2 2/5-pound portions, we need to divide 35/72 by 2 2/5. We can do this by dividing the numerator by the denominator and rounding down to the nearest whole number:

(35/72) ÷ (12/5) ≈ 0.818 ≈ 0

So, Walter stored the remaining flour in 0 whole 2 2/5-pound portions. However, he did store the remaining flour in 35/72 of a 2 2/5-pound portion, which is less than one portion. Therefore, we can say that he stored the remaining flour in 0.35 of a 2 2/5-pound portion, or approximately 0.35 × 2 2/5 = 0.875 pounds of flour per portion.

Finally, to find the number of 2 2/5-pound portions, we divide the total remaining flour by the amount in each portion:

16.8 ÷ 0.875 ≈ 19.2

So, Walter stored the remaining flour in 19 2 2/5-pound portions, with a small amount of flour left over.

There is about a 10.4% probability that a sample proportion will be an over- or underestimate of the parameter by more than 5%.

The error of 5% is not surprising because it falls within the margin of error for a sample of 100 with a 95% confidence level. To find the probability that a sample proportion will be an over- or underestimate of the parameter by more than 5%, we need to use the formula for the margin of error:

Margin of error = zsqrt(p(1-p)/n)

where z is the z-score corresponding to the desired confidence level (1.96 for 95% confidence), p is the estimated proportion from the population (0.3 in this case), and n is the sample size (100 in this case). Plugging in the values, we get:

Margin of error = 1.96sqrt(0.30.7/100) = 0.088

So the margin of error is 8.8%. To find the probability of a sample proportion being an over- or underestimate by more than 5%, we need to find the area under the normal curve beyond 0.05 in either direction. This can be done using a standard normal table or calculator, and the probability is approximately 0.104.

Therefore, there is about a 10.4% chance that a sample proportion will be an over- or underestimate of the parameter by more than 5%.

Area is a measure of the amount of space inside a two-dimensional shape, such as a square, rectangle, triangle, circle, or any other shape that has a length and a width. It is usually measured in square units, such as square inches, square feet, or square meters.

To find the area of △ABC, we can use the formula:

A = (1÷2)bh

where A is the area of the triangle, b is the length of the base, and h is the height.

In △ABC, we can use AB as the base and drop a perpendicular from A to BC to find the height. Let D be the foot of the perpendicular from A to BC.

First, we can find BD using the trigonometric ratio for the angle 27°:

tan(27°) = BD/AB

BD = AB * tan(27°)

BD = 7.8 ft * 0.5095

BD ≈ 3.97 ft

Next, we can find the length of CD:

CD = BC - BD

CD = 10.7 ft - 3.97 ft

CD ≈ 6.73 ft

Now we can use the Pythagorean theorem to find the length of AD:

AD*AD= AB*AB - BD*BD

AD* AD = (7.8 * 7.8 )  - (3.97 * 3.97)

AD ≈ 6.99 ft

Finally, we can use the formula for the area of the triangle:

A = (1÷2)bh

A = (1÷2)(7.8 ft)(6.99 ft)

A ≈ 27.28

Experimental Probability:

The experimental probability of an event is found by dividing the number of times the event occurs by the total number of trials. In this case, the name Grace was chosen 15 times out of 116 trials, so the experimental probability of choosing Grace is:

Experimental Probability = Number of times Grace was chosen / Total number of trials

Experimental Probability = 15 / 116

Experimental Probability = 0.1293 or approximately 12.93%

Theoretical Probability:

The theoretical probability of an event is found by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, there are six names in the hat, so the probability of choosing Grace is:

Theoretical Probability = Number of favorable outcomes / Total number of possible outcomes

Theoretical Probability = 1 / 6

Theoretical Probability = 0.1667 or approximately 16.67%

If the number of names in the hat were different, both the experimental and theoretical probabilities would change. For example, if there were only three names in the hat, the theoretical probability of choosing Grace would be 1/3 or approximately 33.33%. The experimental probability would also change based on the number of times Grace was chosen out of the total number of trials. As the number of names in the hat increases, the theoretical probability of choosing Grace decreases, and the experimental probability becomes more accurate as the number of trials increases.

Standard deviation of the spending is $2.81

Distribution follows t-distribution,

The management is interested in the middle 90% of the customers (spending wise)Sample contains 41 customers

In order to find the cut-off values, we need to find the z-values for 5% and 95% of the data set.

Lower cut-off = Average spending - z × (Standard deviation / √n)

Upper cut-off = Average spending + z × (Standard deviation / √n)

Here,

n = 41,

Average spending = $9.41,

Standard deviation = $2.81

Let's find the value of z from the t-distribution.

t-distribution is a symmetric distribution.

Since we need to find the middle 90%, we need to find the area outside of 5% (on both sides of the distribution).

For a 90% confidence interval, the area outside of 5% on both sides of the t-distribution is [tex]\frac{0.05}{2}[/tex] = 0.025.

As per the t-distribution table, for 40 degrees of freedom, the t-value for 0.025 is 2.021..

Lower cut-off = $9.41 - 2.021 × ()

Lower cut-off = $8.44

Upper cut-off = $9.41 + 2.021 × ($2.81/√41)

Upper cut-off = $10.38

Let's call the number of quarters the man has "q".We know that the man has 32 coins in total, so we can write:

d + q = 32We also know that the total value of the change is 515 cents. Since dimes are worth 10 cents and quarters are worth 25 cents, we can write an equation for the total value in cents:

10d + 25q = 515

We now have two equations with two variables, which we can solve simultaneously. Let's rearrange the first equation to solve for one of the variables:

d = 32 - q

We can substitute this expression for "d" into the second equation:

10(32 - q) + 25q = 515Simplifying and solving for "q", we get:

320 - 10q + 25q = 515

15q = 195

q = 13

So the man has 13 quarters. We can substitute this value into the first equation to find the number of dimes:

d + 13 = 32

d = 19

Therefore, the man has 19 dimes and 13 quarters.

There are 19 dimes and 13 quarters.

Let x represent the number of dimes and y represent the number of quarters.

There are a total of 32 coins, so:

x + y = 32

We know that the total value of the change is 515 cents

. The value of x dimes is 10x cents and the value of y quarters is 25y cents. So:

10x + 25y = 515

We can simplify the first equation by solving for one variable in terms of the other:

x + y = 32x = 32 - y

Now we can substitute this expression for x into the second equation:

10(32 - y) + 25y = 515

Simplify and solve for y:

320 - 10y + 25y = 515

15y = 195y

y = 13

So there are 13 quarters. We can find the number of dimes by substituting y = 13 into x + y = 32:x + 13 = 32x = 19So there are 19 dimes.

So, There are 19 dimes and 13 quarters.
