Answer:

(a) seems to be the closest to being correct of these five statements.

Step-by-step explanation:

Let's go through the list of possible descriptors:

a) There are no outliers. This seems to be the response most likely to be correct.

b) The distribution is not skewed left. It's skewed right.

c) The center is not 44. From what I see, the center is 48.

d) This distribution is not bimodal; it does not have two peaks.

d) The spread is not 38 to 67; it's 29 to 67.

A sphere has a radius of 2x + 5. Which polynomial in standard form best describes the total surface area of the sphere? Use the

faust18 [17]

Start with the given formula for the surface area of a sphere.

$S = 4 \pi r^2$

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.

$S = 4 \pi (2x + 5)^2$

$S = 4 \pi (4x^2 + 20x + 25)$

$S = 16 \pi x^2 + 80 \pi x + 100 \pi$

Factor: x^2 - 8x + 16

Mazyrski [523]

X^2-8x+16= (x-4)^2 because -4 and -4 add to -8 but multiply to 16. Hope that helped.

The frequency f of vibration of a violin string is inversely proportional to its length L. The constant of proportionality k is

Natali5045456 [20]

Answer:

(A) $f=\frac{k}{L}$

(B) Frequency becomes half.

Step-by-step explanation:

We have been given that the frequency f of vibration of a violin string is inversely proportional to its length L. The constant of proportionality k is positive and depends on the tension and density of the string.

(A) We know that two inversely proportional quantities are in form $y=\frac{k}{x}$ , where y is inversely proportional to x and k is constant of proportionality.

Upon substituting our given values, we will get:

$f=\frac{k}{L}$

Therefore, our required equation would be $f=\frac{k}{L}$ .

(B) For part, we have been given that length is twice, so our new frequency will be $f_n$ and new length $L_n$ is $2L$ .

Upon substituting $2L$ in our equation as:

$f_n=\frac{k}{L_n}$

$f_n=\frac{k}{2L}$

$f_n=\frac{1}{2}\cdot \frac{k}{L}$

$f_n=\frac{1}{2}\cdot f$

Upon comparing $f_n$ with $f$ , we can see that $f_n$ is half the value of $f$ .

Therefore, the frequency of vibration of violin gets half, when we double the length of the string.

I Need help with Number 2 And 4 asap plz

2. There are 18 other bottles in the fridge, because .6 of 30 is 18. 30 – 18 is 12, so there are 12 bottles of orange juice and cranberry juice.

4. If the probability of an event is 25%, then the probability of <em>not</em> that event is the other part of 100%. In other words, 1 – .25 = .75.
