Answer:

15.87% (2 d.p.)

Step-by-step explanation:

If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:

[tex]\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]

Given:

Therefore, if the weights of adult male rhesus monkeys are normally distributed:

[tex]\boxed{X \sim\text{N}(17, 3^2)}[/tex]

where X is the weight of an adult male rhesus monkey.

To calculate the probability that a randomly selected adult male rhesus monkey has a weight less than 14 pounds, we need to find P(X < 14).

Calculator input for "normal cumulative distribution function (cdf)":

⇒ P (X < 14) = 0.158655253...

⇒ P (X < 14) = 15.8655253...%

⇒ P (X < 14) = 15.87%

Therefore, the probability that a randomly selected adult male rhesus monkey has a weight less than 14 pounds is approximately 15.87% (2 d.p.).

Answer:

f = 53.13 degrees

Step-by-step explanation:

An isosceles triangle has two equal sides, so in this case the sides of length 60cm are equal. The base angle (f) is opposite the base of the triangle, which is the side of length 100cm.

To find the base angle, we can use the law of cosines.

c^2 = a^2 + b^2 - 2ab*cos(f)

where c is the hypotenuse (the side of length 100cm), a and b are the legs (the sides of length 60cm), and f is the base angle we are trying to find.

Substituting in the given values, we get:

100^2 = 60^2 + 60^2 - 2(60)(60)cos(f)

Simplifying this equation, we get:

10000 = 3600 - 3600cos(f)

so

cos(f) = (10000-3600)/3600 = 6400/3600 = (8/3)^2

then

f = cos^-1((8/3)^2)

Therefore, f = 53.13 degrees

The given expressions are the results of applying the function f to a value that is being multiplied by -3 or 3.

f(-3x) means that the function is applied to -3x, in this case the output is -3f(x)

f(3x) means that the function is applied to 3x, in this case the output is 3f(x)

It should be noted that the function f(x) could be any type of function and the output depends on the function's definition.

Answer:

.125%

Step-by-step explanation:

Answer:

To find the percent of tourists buried up to their neck in sand, you can divide the number of buried tourists by the total number of tourists and multiply by 100.

12 buried tourists / 9,600 total tourists = 0.00125

0.00125 x 100 = 0.125 or 12.5%

So, 12.5% of the tourists were buried up to their neck in sand.

Let u and v be a vectors. Then u can be broken up into two components, r and s such that r is parallel to v and s is perpendicular to v.

The component of u perpendicular to v is referred to as s, while r is referred to as the projection of u onto v. Then, u v = u1v1 + u2v2 + + unvn is the dot product of u with v.

Keep in mind that u v is defined when u and v have the same number of components and that the dot product of two vectors is a scalar. Though the dot product is a union of two vectors, the outcome is not a vector, which is an intriguing observation.

Step-by-step explanation:

The average age of the zebras at the zoo can be found by adding up all of the ages and dividing by the number of zebras.

In this case, the ages of the zebras are 8, 11, 17, 7, 19.

To find the average age, we add up all of the ages: 8 + 11 + 17 + 7 + 19 = 62

Then we divide by the number of zebras (5): 62/5 = 12.4

So, the average age of the zebras at the zoo is 12.4 years old.

To find the standard deviation, we first need to find the variance.

The variance is the average of the squared differences from the mean.

We can find the variance by taking each value, subtracting the mean, squaring the result, and dividing by the number of zebras.

The standard deviation is the square root of the variance

So, the standard deviation of the zebras age is difficult to calculate by hand, but we can use a calculator to find the standard deviation, which is approximately 4.345 years.

Rounding to the nearest tenth:

The average age is 12.4 years old

The standard deviation is 4.3 years

Tarek has $50 dollars.

Step-by-step explanation:

Let's say Hasan has "x" dollars at first. The question tells us that Nabila has six more dollars than Hasan has. This means that Nabila has "x + 6" dollars. The last given information is that Tarek has two times what Nabila has. So, Tarek has "2x + 12" dollars, basically.

Then, we can add up all these amounts to find out the result for each person.

We found what is "x". This means that we actually found the answer.

Hasan had "x" dollars so he has $19 dollars.

Nabila had "x + 6" dollars so she has $25 dollars.

Finally, Tarek had "2x + 12" dollars or two times of what Nabila has so he has $50 dollars.

Ratio of sine of angle of incidence to the sine of angle of refraction is constant by Snell’s law.

According to Snell's Law, the refractive index, or n, is a constant that represents the ratio of a wave's angle of incidence to angle of refraction as it passes through a boundary between two mediums.

₁n₂=n₂/n₁=sin θ₁/sin θ₂= v₁/v₂,

where n is the refractive index,

v is the speed in different medium and θ is the angle between the normal and the ray at the surface of boundary.

If we do an experiment and measure the angles of incidence and refraction, we will discover that a straight line passing through the origin results from plotting the sine of the angles of incidence and refraction.

This shows that the sine of the angle of incidence and the sine of the angle of refraction are directly related, and that the ratio of the two will result in a constant value that we refer to as the refractive index. The ratio of the sines of the angles corresponds to the proportion of the wave speeds through the medium.

Thus, we can say that refractive index is constant for a given pair of media.

For the roots to be real and equal, the value of k should be 9, -9.

The complete question is:

For what values of k are the roots of the quadratic equation 3x2 + 2kx + 27 = 0 real and equal?      

For the roots of the equation to be real and equal, we first compare the given quadratic equation with standard form of quadratic equations, which is: [tex]ax^2+ bx+ c=0[/tex]

Thus, a = 3; b= 2k and c = 27

The APR if the finance terms are $21.99 per week for 52 weeks is 83.48%. Hence option 4 is correct.

The annual percentage rate, or APR, is the interest rate that is charged on a loan balance that is still outstanding. The expected cost of the annual fees connected with a certain sort of borrowing is what the APR conceptually reflects.

APR is a commonly used formula by lenders that enables borrowers to compare various loan choices. The stated interest rate on a loan is typically insufficient on its own to help borrowers choose the best loan option.

A loan with a low stated interest rate could also have significant costs attached that should not be disregarded. The best alternative might be a loan with a smaller fee structure and a higher advertised interest rate. APR is calculated as (Periodic Interest Rate x 365 Days) x 100 i.e.

[tex]$\mathrm{APR=\left(\left(\frac{\frac{Fees+Interest}{Principal}}{n} \right) \times 365 \right) \times 100}[/tex]

​where:

Interest = Total interest paid over life of the loan

Principal = Loan amount

n = Number of days in loan term

Fees = 0

​Interest = 2​Interest = $519.48

Principal = $624.00

n = 52 × 7 = 364 days

Plug the data in the formula:-

[tex]$\mathrm{APR=\left(\left(\frac{\frac{0+519.48}{624}}{364} \right) \times 365 \right) \times 100}[/tex]

APR = 83.48%

By applying the division formula, the number of times the ferry crossed the river would be 6 times.

To divide something means to split it into two or more equal pieces, areas, classes, categories, groups, or divisions. Dividing something means to give each component to a separate group, or to create equal parts from the whole. When doing division, the resulting value may or may not be an integer. The final result may occasionally be expressed as a decimal.

To calculate the division, we can use this following formula:

Dividend ÷ Divisor = Quotient + Remainder.

Where:

Dividend = the number, which is being divided

Divisor = the number, which divides the number (dividend) into equal parts

Quotient = the result of the division operation

Remainder = the leftover number in the division operation.

In this case, we are given that:
