To find the horizontal distance between Luke and the kite, we can use trigonometry. The horizontal distance is equal to the length of the string multiplied by the cosine of the angle. Let's calculate it:

Horizontal distance = 400 feet * cos(50°)

Using a calculator, we can find the cosine of 50 degrees to be approximately 0.6428. Multiplying this by 400 feet, we get:

Horizontal distance = 400 feet * 0.6428 ≈ 257.12 feet

Therefore, the horizontal distance between Luke and the kite is approximately 257.12 feet when rounded to the nearest hundredth.

Step-by-step explanation:

The phase shift for the function y = sin(θ + 90 degrees) is -90 degrees or -π/2 radians.

The standard form of a sine function is y = A sin(Bθ + C),

where

here  the equation y = sin(θ + 90 degrees) can be rewritten as

y = sin ( 1θ + 90 degrees), which matches the standard form with A = 1, B = 1, and C = 90 degrees.

so to find tthe phase shift, we need to find the value of θ that makes the argument of the sine function equal to zero.

That i s

θ + 90 degrees = 0

θ = -90 degrees

Therefore, the phase shift is -90 degrees or -π/2 radians.

Rounding to the nearest tenth, the probability of selecting a divisor of 18 from the given cards is approximately 33.3%.

To find the probability of selecting a divisor of 18 from the given cards (2, 3, 4), we need to determine how many of those cards are divisors of 18 and divide it by the total number of cards.

Divisors of 18 are numbers that evenly divide 18 without leaving a remainder. The divisors of 18 are 1, 2, 3, 6, 9, and 18.

Out of the given cards (2, 3, 4), only the number 2 is a divisor of 18.

Since there is only 1 card out of the total 3 cards that is a divisor of 18, the probability (P) of selecting a divisor of 18 can be calculated as:

P = Number of favorable outcomes / Total number of possible outcomes

P = 1 / 3

To express the probability as a percentage, we multiply the probability by 100:

P = (1 / 3) * 100 = 33.3%

Step-by-step explanation:

The interval width is 6, while the interval with the most values is 12 -18. There are 30 values in the dataset and the number of values that are 18 or greater is 12. The interval that the number 12 falls into is 12 - 18.

The interval width is gotten by dividing the range of values by the number of intervals.

This gives us: 30 - 0/5  = 6

So, the interval width is 6.

The interval that has the most values is 12 - 18. This is the point where we have the bars with the longest range.

To find the least common denominator (LCD) of 2/3 and 2/10, determine the smallest common multiple of the denominators.

The prime factorization of 3 is 3, and the prime factorization of 10 is 2 * 5.

To find the LCD, we take the highest power of each prime factor that appears in either denominator:

Therefore, the LCD is  2 * 3 * 5 = 30.

The exact length of the arc formed by a central angle measuring 120° in a circle with a radius of 12.3 cm is 8.2π cm.

To calculate the exact length of an arc formed by a central angle measuring 120° in a circle with a radius of 12.3 cm, we can use the formula:

Arc Length = (Central Angle / 360°) * Circumference

First, let's calculate the circumference of the circle:

Circumference = 2 * π * radius

Substituting the given radius value into the formula, we get:

Circumference = 2 * π * 12.3 cm

Circumference = 24.6π cm

Now, let's calculate the arc length using the central angle of 120°:

Arc Length = (120° / 360°) * 24.6π cm

Arc Length = (1/3) * 24.6π cm

Arc Length = 8.2π cm

Therefore, the exact length of the arc formed by a central angle measuring 120° in a circle with a radius of 12.3 cm is 8.2π cm.

It's important to note that in this case, since the central angle is given in degrees, the result is expressed in terms of π. If you need a decimal approximation, you can calculate the numerical value using an appropriate approximation for π.

Answer:

Grace has 120 spoons in her collection

Step-by-step explanation:

We can allow the variable E to represent the number of spoons Ethan has and G to represent the number of spoons Grace has.

Since we're told that Grace has 2.5 times as many spoons as Ethan, we know that

G = 2.5E

We plug in 48 for E and simplify to find the total amount of spoons Grace has:

G = 2.5 * 48

G = 120

Thus, Grace has 120 spoons in her collection as 120 is 2.5 times greater than 48 (the number of spoons Ethan has)

The normal distribution is solved and the retirement ages are normally distributed

P(x ≤ 62) ≈ 22.7%

P(x ≥ 70) ≈ 10.6%

P(55 ≤ x ≤ 60) ≈ 14.5%

P(60 ≤ x ≤ 70) ≈ 78.9%

Given data ,

To solve these probability questions, we can use the properties of the normal distribution. Let's calculate each probability:

a)

P(x ≤ 62):

To find this probability, we need to calculate the z-score corresponding to x = 62 and then find the area under the standard normal distribution curve to the left of that z-score. The formula to calculate the z-score is:

z = (x - mean) / standard deviation

In this case:

z = (62 - 65) / 4 = -0.75

Using a standard normal distribution table or a calculator, we can find that the area to the left of z = -0.75 is approximately 0.2266 or 22.7%

b)

P(x ≥ 70):

To find this probability, we need to calculate the z-score corresponding to x = 70 and then find the area under the standard normal distribution curve to the right of that z-score. Again, we use the z-score formula:

z = (x - mean) / standard deviation

In this case:

z = (70 - 65) / 4 = 1.25

Using a standard normal distribution table or a calculator, we can find that the area to the right of z = 1.25 is approximately 0.1056 or 10.6%

c)

P(55 ≤ x ≤ 60):

To find this probability, we need to calculate the z-scores corresponding to x = 55 and x = 60, and then find the area between those two z-scores under the standard normal distribution curve. Again, we use the z-score formula:

z = (x - mean) / standard deviation

For x = 55:

z1 = (55 - 65) / 4 = -2.5

For x = 60:

z2 = (60 - 65) / 4 = -1.25

Using a standard normal distribution table or a calculator, we can find that the area between z = -2.5 and z = -1.25 is approximately 0.1446 or 14.5%

d)

P(60 ≤ x ≤ 70):

To find this probability, we need to calculate the z-scores corresponding to x = 60 and x = 70, and then find the area between those two z-scores under the standard normal distribution curve.

Using the same z-score formula as above:

For x = 60:

z1 = (60 - 65) / 4 = -1.25

For x = 70:

z2 = (70 - 65) / 4 = 1.25

Using a standard normal distribution table or a calculator, we can find that the area between z = -1.25 and z = 1.25 is approximately 0.7887 or 78.9%

P(x ≤ 62) is approximately 22.7%.

P(x ≥ 70) is approximately 10.6%.

P(55 ≤ x ≤ 60) is approximately 9.9%.

P(60 ≤ x ≤ 70) is approximately 89.4%.

We have,

To solve these probability problems, we can use the standard normal distribution and Z-scores.

First, we need to convert the given values to Z-scores using the formula: Z = (X - μ) / σ, where X is the given value, μ is the mean, and σ is the standard deviation.

a)

P(x ≤ 62):

Z = (62 - 65) / 4 = -0.75

Using a standard normal distribution table or a calculator, we can find the corresponding area under the curve for a Z-score of -0.75.

This gives us a probability of approximately 0.2266.

To convert this probability to a percentage, we multiply by 100: 0.2266 * 100 ≈ 22.7%

b)

P(x ≥ 70):

To find the probability of x being greater than or equal to 70, we can use the complement rule: P(x ≥ 70) = 1 - P(x < 70)

Z = (70 - 65) / 4 = 1.25

Using a standard normal distribution table or a calculator, we can find the probability of a Z-score being less than 1.25, which is approximately 0.8944.

Now,

We can calculate P(x ≥ 70) = 1 - P(x < 70) = 1 - 0.8944 = 0.1056.

To convert this probability to a percentage, we multiply by 100: 0.1056 * 100 ≈ 10.6%

c)

P(55 ≤ x ≤ 60):

Z1 = (55 - 65) / 4 = -2.5

Z2 = (60 - 65) / 4 = -1.25

Using a standard normal distribution table or a calculator, we can find the probability of a Z-score being less than -1.25, which is approximately 0.1056.

Using the same method, we can find the probability of a Z-score being less than -2.5, which is approximately 0.0062.

Now, we can calculate the probability between -2.5 and -1.25 by subtracting the two probabilities:

P(-2.5 ≤ Z ≤ -1.25) = P(Z ≤ -1.25) - P(Z ≤ -2.5) = 0.1056 - 0.0062 = 0.0994.

To convert this probability to a percentage, we multiply by 100: 0.0994 x 100 ≈ 9.9%

d)

P(60 ≤ x ≤ 70):

Using the same Z-scores as in part c), we can find the probability of a Z-score being less than -1.25, which is approximately 0.1056.

Using the complement rule, we can find P(60 ≤ x ≤ 70) = 1 - P(x < 60) = 1 - 0.1056 = 0.8944.

To convert this probability to a percentage, we multiply by 100: 0.8944 * 100 ≈ 89.4%

Therefore,

P(x ≤ 62) is approximately 22.7%.

P(x ≥ 70) is approximately 10.6%.

P(55 ≤ x ≤ 60) is approximately 9.9%.

P(60 ≤ x ≤ 70) is approximately 89.4%.
