A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number
kari74 [83]

Answer:

0.4

Step-by-step explanation:

These are the relative frequencies of each face (data are missing in the text of the problem):

Number Showing  on Top Face   Frequency

1 0

2 3

3 3

4 6

5 3

6 5

The probability to obtain a certain number when throwing the dice is given by

p(x_i)=\frac{f_i}{\sum f}

where

f_i is the relative frequency of the number x_i to occur

\sum f is the sum of the relative frequencies

Here the sum of the frequencies is:

\sum f=0+3+3+6+3+5=20

For number 5 here, we have:

f_5 = 3 (from the table)

So the probability of getting a 5 is

p(5)=\frac{3}{20}

For number 6 here, we have

f_6=5

So the probability of getting a 6 is

p(6)=\frac{5}{20}

So the probability to obtain either a 5 or a 6 in the next rolling is:

p(5\cup 6)=p(5)+p(6)=\frac{3}{20}+\frac{5}{20}=\frac{8}{20}=0.4

ZA and ZB are supplementary angles. If m_A
KatRina [158]

Answer:

∠A = 107

∠B = 73

Step-by-step explanation:

∠A ,  ∠B are supplementary. So, ∠A + ∠B = 180

5x + 27 + 5x - 7 = 180

5x + 5x  + 27 - 7 = 180       {Combine like terms}

             10x + 20=180

                    10x = 180 -20

                   10x = 160

                      x = 160/10

x = 16

∠A = 5x + 27 = 5*16 + 27 = 80 + 27 = 107

∠B = 5x - 7 = 5*16 - 7 = 80 - 7 = 73

Given: f(x) = 2x-1 and g(x) = 2x-3<br> Find:<br> (fog)(x)<br> HELP PLEASEE!!
Murljashka [212]

Answer:

(fog)(x) = 4x - 7

Step-by-step explanation:

f(x) = 2x-1 and g(x) = 2x-3;

(fog)(x) = f(g(x)

= f(2x - 3) = 2(2x - 3) - 1

= 4x - 6 - 1

= 4x - 7
