Answer: the amount of socks they will collect in four days is less than the amount of socks they plant to collect, in other words 915<1500 socks.

Step-by-step explanation:

If they collect 183 pairs of socks in one day, and there are four days left, then 183 x 5 = 915 (pairs of socks) in five days. They need to collect 1,500 pairs.

A. P(62 or over and has a loan)= 4.05%

B. P(has a loan)=48.6%

C.  P(62 or over and has a loan)=0.486

15% of the population are 62 or over

27% of those 62 or over have loans

54% of those under 62 have loans

To find the probabilities that a person fits into the following categories:

a) 62 or over and has a loan:

P(62 or over) = 15% = 0.15

P(62 or over and has a loan) = P(62 or over) * P(have a loan|62 or over)

= 0.15 * 0.27

= 0.0405 or 4.05%

b) Has a loan:

P(has a loan) = P(62 or over) * P(have a loan|62 or over) + P(under 62) * P(have a loan|under 62)

= 0.15 * 0.27 + 0.85 * 0.54

= 0.486 or 48.6%

c) P(62 or over and has a loan) = P(62 or over) * P(have a loan|62 or over)

= 0.15 * 0.27

= 0.0405 or 4.05%

P(62 or over) = 0.15 and P(have a loan) = 0.486

So, P(62 or over and has a loan) ≠ P(62 or over) * P(have a loan)

Hence, the events that a person is 62 or over and that the person has a loan are not independent.

Got it right on math nation. Hope this helps!

Answer:

5

Step-by-step explanation:

Answer:  5

Step-by-step explanation:

We rerange the number in 1,2,3,4,9,12,13

The median is 4, and a number x between 4 and 9.

We have 4.5 for median, which is the average of 4 and x.

(4 + x) /2 = 4.5

4 + x = 9

x = 5

The margin of error for the 97% confidence interval is approximately 0.021

The margin of error for the 97% confidence interval used to estimate the population proportion can be calculated using the formula: margin of error = z * √((p * (1 - p)) / n), where z is the z-score corresponding to the desired confidence level, p is the sample proportion, and n is the sample size.

To calculate the margin of error, we need to determine the sample proportion, which is the ratio of the number of adults who said they had tried alternative medicine to the total sample size: p = 744/1485 = 0.5017.

The z-score for a 97% confidence level is approximately 1.8808 (obtained from the standard normal distribution table).

Plugging in the values:

margin of error = 1.8808 * √((0.5017 * (1 - 0.5017)) / 1485) ≈ 0.021

Therefore, the margin of error for the 97% confidence interval is approximately 0.021, rounded to three decimal places.

Answer: i dont know

Step-by-step explanation:

For a small change in x (dx), the corresponding change in y (dy) is given by the equation dy = (6x² - 4)dx.

To find the relationship between a small change in x (dx) and the corresponding change in y (dy) for the function f(x) = 2x³ - 4x, we can differentiate the function with respect to x.

f(x) = 2x³ - 4x

Differentiating both sides with respect to x:

f'(x) = d/dx (2x³ - 4x)

f'(x) = 6x² - 4

Now, we can express the relationship between dx and dy in the form of dy = f'(x)dx:

dy = (6x² - 4)dx

Therefore, for a small change in x (dx), the corresponding change in y (dy) is given by the equation dy = (6x² - 4)dx.

Answer/Step-by-step explanation:

a. Given that 32° is the reference angle, thus:

Hypotenuse is the side opposite to the right angle

Opposite side is opposite to the defence angle = x

Adjacent side is adjacent to defence angle = 15 m

b. Recall SOHCAHTOA.

We know the length of the adjacent side. We are asked to find x, which is the opposite side. So, we are dealing with Opposite side and Adjacent side.

The trigonometric function we will use to find x would be TOA:

That is,

Tan θ = Opp/Adj

c. Applying TOA:

Tan θ = Opp/Adj

θ = 32°

Opp = x

Adj = 15 m

Plug in the values

Tan 32 = x/15

15 × Tan 32 = x

9.37304028 = x

x = 9.4 (nearest tenth)

Answer:

46 + W = 231

Step-by-step explanation:

Answer:

My guess: 231 = 46 + b

Step-by-step explanation: Because they didn't mention how many were colored brown, we would use a variable to represent them, in this case I use b. But we do know 46 of them were white. so the equation would simply be 231 = 46 + b. After you add 46 and b you will get the total to 231. You can find b from subtracting 231 to 46. Then add b to 46 and get the total of 231

Explanation: You did everything right in terms of the steps you took. It looks like you accidentally wrote "1" instead of "-4" as the answer to "2(-2)".

(a) The statement "The sum of 4 and 6 is prime if and only if either 4 or 6 is prime" is false.

(b) The statement "If 3 divides 20, then 6 divides 20" is true.

(a) The sum of 4 and 6 is prime if and only if either 4 or 6 is prime.

To determine the truth value of this statement, we need to evaluate both directions separately.

Direction 1: If the sum of 4 and 6 is prime, then either 4 or 6 is prime.

This direction is true because the sum of 4 and 6 is 10, which is not a prime number. Therefore, the statement is true.

Direction 2: If either 4 or 6 is prime, then the sum of 4 and 6 is prime.

This direction is false because neither 4 nor 6 is a prime number, but their sum is 10, which is not a prime number. Therefore, the statement is false.

Since the statement is not true in both directions, the overall statement is false.

(b) If 3 divides 20, then 6 divides 20.

To determine the truth value of this statement, we need to evaluate the implication.

If 3 divides 20, then 6 divides 20.

This statement is true because 3 divides 20 (3 is a factor of 20), and 6 also divides 20 (6 is a factor of 20). Therefore, the statement is true.

Let's denote the lengths of the legs of the right triangle as a and b, and the length of the hypotenuse as c. We are given that the altitude perpendicular to the hypotenuse is 12 cm.

Using the Pythagorean theorem, we have:

[tex]a^2 + b^2 = c^2[/tex]

The perimeter of the right triangle is given by:

Perimeter = a + b + c

We want to express the length of the hypotenuse (c) as a function of the perimeter.

Rearranging the equation for the perimeter, we have:

c = Perimeter - (a + b)

Substituting the equation for c into the Pythagorean theorem equation, we get:

[tex]a^2 + b^2[/tex] = (Perimeter - [tex](a + b))^2[/tex]

Expanding and simplifying, we have:

[tex]a^2 + b^2[/tex]= [tex]Perimeter^2[/tex] - 2Perimeter(a + b) +[tex](a + b)^2[/tex]

Simplifying further:

[tex]a^2 + b^2[/tex]= [tex]Perimeter^2[/tex]- 2Perimeter(a + b) + a^2 + 2ab + b^2

The terms with [tex]a^2[/tex] and [tex]b^2[/tex]cancel out, giving:

[tex]2ab = Perimeter^2 - 2Perimeter(a + b)[/tex]

Dividing both sides by 2, we have:

[tex]ab = (Perimeter^2 - 2Perimeter(a + b))/2[/tex]

[tex]ab = (Perimeter^2 - 2Perimeter(a + b))/2[/tex]

Now, since we are given that the altitude perpendicular to the hypotenuse is 12 cm, we know that:

ab = [tex]12^2 = 144[/tex]

We can solve this equation for either a or b, and then substitute the value into the expression for the hypotenuse (c):

For example, let's solve for a:

a = 144/b

Substituting this into the expression for c

c = Perimeter - (a + b)

c = Perimeter - (144/b + b)

Therefore, the length of the hypotenuse (c) can be expressed as a function of the perimeter.

The Volterra integral equation:

x(t) - xo = ∫[to, t] y(s) ds

y(t) - x₁ = ∫[to, t] f(s, x(s)) ds

(a) To write the initial value problem dx = f(t, x), x(to) = xo dt as an integral equation, we can use the integral representation of the solution.

Let's consider the integral equation:

x(t) = xo + ∫[to, t] f(s, x(s)) ds

This integral equation is of the Volterra type, as it involves a definite integral and depends on the function x(s) evaluated over the interval [to, t].

(b) To transform the second-order initial value problem d²x/dt² = f(t, x), x(to) = xo, x'(to) = x₁ into a Volterra integral equation, we can introduce a new variable, y(t), defined as the derivative of x(t):

y(t) = dx/dt

Now, we can rewrite the second-order differential equation as a system of first-order differential equations:

dx/dt = y(t)

dy/dt = f(t, x)

To represent this system as an integral equation, we'll integrate both equations from to to t.

This yields:

x(t) - xo = ∫[to, t] y(s) ds

y(t) - x₁ = ∫[to, t] f(s, x(s)) ds

Combining these two equations, we obtain the Volterra integral equation:

x(t) - xo = ∫[to, t] y(s) ds

y(t) - x₁ = ∫[to, t] f(s, x(s)) ds

This integral equation is also of the Volterra type, involving definite integrals and depending on the functions x(s) and y(s) evaluated over the interval [to, t].
