Answer:

B. the mean

Step-by-step explanation:

According to the Bar Chart shown, the number of DVDs sold at a local music store during one week are displayed.

Therefore, the measure(s) of central tendency that can be used to determine the average number of DVDs sold each day is the mean.

This is because the mean is the sum total of the number of DVDs sold, divided by the number, which gives the average.

when you divide a whole number by a fraction with a numerator of 1, explain how you can find the quotient

Kobotan [32]

Something like 4//1/255 ?
just multiply The number you started with be the denominator of the fraction.

4 * 255 = 1020

The reason why is that though I didn't say so you are actually multiply both top and bottom by 255

4 * 255
==
1 * 255
--
255
The bottom 255s cancel. and you are left with 4 * 255 on the top.
Short cut you want. Short cut you get.
Thanks for posting.

I believe your answer is:

$g(3) = -8$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Evaluating the function...}}\\\\g(x)=-4x+4; g(3)\\\\--------------\\\rightarrow g(3)=-4(3)+4\\\\\rightarrow g(3) = -12 + 4\\\\\rightarrow \boxed{g(3)=-8}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

George is 2 in. taller than the quotient of Myron's height and 3. Let M represent Myron's height, in inches. Write an expression

NikAS [45]

Answer:

G = M/3 + 2

Step-by-step explanaion

We can interpret the quotient of Myrons height and 3 as "M/3" and we add "+2" to account for the "2 in. taller" part of the problem. We can also represent George's height using "G"

One mole of iron (6 × 1023 atoms) has a mass of 56 grams, and its density is 7.87 grams per cubic centimeter, so the center-to-c

Answer:

a) k $_{s}$ = 3.6 N/m ; b) 9.43 * 10¹²; c) 1.18 * 10¹¹; d) 75.08 N/m

Step-by-step explanation:

Length of iron bar = L = 2.7m;

side length of cross section = a = 0.07cm = 0.0007m;

x = 2.7 cm = 0.027m;

m = 100kg;

ρ = 7.87gm/cm³;

da = 2.28 * 10⁻¹⁰m;

Fnet = F - mg

where Fnet = 0

So,

F = mg where F=k $_{s}$ x

k $_{s}$ = mg/x = 100*9.8/0.027

k $_{s}$ = 3.6 N/m

Nchain = Aw/Aa =a²/(da)²

= (o.ooo7)²/(2.28 * 10⁻¹⁰)²

= 9.43 * 10¹²

Nbond = L/da = 2.7/2.28 * 10⁻¹⁰

= 1.18 * 10¹¹

Spring stiffness of wire = ksi = (Nbondk $_{s}$ )/Nchain

= [(1.18* 10¹¹)(6*10⁴)]/(9.43 * 10¹²)

= 75.08 N/m
