Which is an example of discrete data?

1 answer:

6 0

Discrete data in information that we collect that can be counted and that only has a certain number of value. EXAMPLES OF DISCRETE DATA: include the number of people in a class, test questions answered correctly, and home runs hit.

Hope this helps :)

Answer:

A) f^-1(x)=(x-8)^3+2

Step-by-step explanation:

To find the function inverse, switch the x with y and solve for y.

$y=\sqrt[3]{x-2}+8 \\\\x=\sqrt[3]{y-2}+8\\\\(x-8)^3 = y-2\\\\ (x-8)^3 + 2 = y$

2x+3y=41 and 5x+4y=85

Sever21 [200]

Answer:

5x+4y=85-

Slope = -2.500/2.000 = -1.250

x-intercept = 85/5 = 17

y-intercept = 85/4 = 21.25000

2x+3y=41-

Slope = -1.333/2.000 = -0.667

x-intercept = 41/2 = 20.50000

y-intercept = 41/3 = 13.66667

What does x and y equal

GaryK [48]

Answer:

x=5, y=-3

Step-by-step explanation:

we can find the answer by plugging in x=3y+14 to the second equation

5(3y+14)-2y=31

simplify

15y+70-2y=31

13y=-39

y=-3

now, plug in this to the initial equation x=3y+14

x=3(-3)+14

x=-9+14

x=5

(cos A + cos b)^2 + (sin A + sin B)^2=?

emmasim [6.3K]

First, we expand the equation:

$cos^{2}A+2cosAcosB+ cos^{2}B+sin^{2}A+2sinAsinB+sin^{2}B$

Then, we combine certain terms in order to simplify them using trigonometry identities.

$cos^{2}A+sin^{2}A+cos^{2}B+sin^{2}B+2cosAcosB+2sinAsinB$

Note these identities:
Pythagoran relation: $cos^{2}A+sin^{2}A = cos^{2}B+sin^{2}B=1$
Sum and Difference Formula/Identities: $cos(A-B) = cosAcosB+sinAsinB$

Thus, if we apply these identities, the simplified equation would be:
$2(cos(A-B))+2$

Simplying further, the answer would be

$2[cos(A-B)+1]$
