Answer: range: (-10,-4,4,10)

Step-by-step explanation: range is y value and domain is x value

f(x) will be ur y

in place of x put the value of domain

example:

f(x) =2x-6

y=2(-2)-6

= -10

2) y=2[1]-6

= -4

like that do the rest of the working to find ur range.

Answer:

the range is : (-10,-4,4,10)

Step-by-step explanation:

calculate :

f(-2) = 2(-2) -6 = -10

f(1) = 2(1) -6 = -4

f(5) = 2(5) -6 = 4

f(8) = 2(8) -6 = 10

the range is : (-10,-4,4,10)

Korolek [52]

Answer:

see below

Step-by-step explanation:

given: size of television is height = 37 in, length = 71 in.

A. using Pythagorean theorem:

parts given are legs which is the sides

looking for the hypotenuse.

B. formula:

a² + b² = c² or H² + L² = D²

where H = height = 37

L = length = 71

D = diagonal (which is req'd)

C. D² = 37² + 71²

D = $\sqrt{1369+ 5041}$

D = $\sqrt{6410}$

D = 80 in (missing length)

D. size of television:

37 x 71 in

Diagonal is 80 in

hope it helps and good luck!

A fair coin is flipped twelve times. What is the probability of the coin landing tails up exactly nine times?

seraphim [82]

Answer:

$P\left(E\right)=\frac{55}{1024}$

Step-by-step explanation:

Given that a fair coin is flipped twelve times.

It means the number of possible sequences of heads and tails would be:

2¹² = 4096

We can determine the number of ways that such a sequence could contain exactly 9 tails is the number of ways of choosing 9 out of 12, using the formula

$nCr=\frac{n!}{r!\left(n-r\right)!}$

Plug in n = 12 and r = 9

$=\frac{12!}{9!\left(12-9\right)!}$

$=\frac{12!}{9!\cdot \:3!}$

$=\frac{12\cdot \:11\cdot \:10}{3!}$ ∵ $\frac{12!}{9!}=12\cdot \:11\cdot \:10$

$=\frac{1320}{6}$ ∵ $3!\:=\:3\times 2\times 1=6$

$=220$

Thus, the probability will be:

$P\left(E\right)=\frac{n\left(E\right)}{n\left(S\right)}$

$=\frac{220}{4096}$

$=\frac{55}{1024}$

Thus, the probability of the coin landing tails up exactly nine times will be:

$P\left(E\right)=\frac{55}{1024}$
