The <u>correct probability</u> is 1/16.

Explanation:

There is 1 section marked 8 out of 8 sections.  This makes the probability of landing on an 8 1/8.

The factors of 4 on this spinner are 1, 2, 4 and 8.  This makes 4 sections out of 8, which makes the probability of landing on a factor of 8 equal 4/8=1/2.

Together, the probability of both events would be 1/8(1/2) = 1/16.

Answer:

Required probability = 1/16

Step-by-step explanation:

When we spin a spinner numbered 1-8, we find that each spin is independent of the other.

HEnce probability for getting any number from 1 to 8 will be equal to 1/8 and remain the same for each spin.

So Probability on two for the first time and factor of 8 on the second time

=Prob (landing on 2)*Prob (landing on any factor of 8)

P(landing on 2) = 1/8

Factors of 8 are 1,2,4,8

Prob (landing on factor of 8) = 4/8

Hence required prob = 1/8(4/8) =1/16

Answer:

Bottom left (each term in pattern X is 1/3...)

Step-by-step explanation:

If you look at the 2nd row, you will recognize that when you multiply 15 times 1/3, you will get 5, which is 1/3 of 15. You will recognize this pattern across the whole table.

Graph the solution of the system of linear inequalities.<br> y≤−4x−4<br> y≥x+2
tamaranim1 [39]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y\leq -4x-4 ----> inequality A

The solution of the inequality A is the shaded area below the solid line y=-4x-4

The y-intercept of the solid line is -4

The x-intercept of the solid line is -1

The slope of the solid line is negative

y\geq x+2 ----> inequality B

The solution of the inequality B is the shaded area above the solid line y=x+2

The y-intercept of the solid line is 2

The x-intercept of the solid line is -2

The slope of the solid line is positive

The solution of the system of inequalities is the shaded area between the two solids line

see the attached figure

It will take total 90 minutes to finish the book and 60 minutes to read the left 40 pages.

<h3>What is Ratio and Proportion ?</h3>

When two numbers can be written as p/q is called a Ratio , and when two ratios are equal they are said to be in proportion .

It is given that

Jeremy is reading a 60-page book.

The time taken to read  20 pages is 30 minutes

Then it can be written as 20:30 = 2:3

The rate of reading is same so To read the rest 40 pages is given by

40:x

40: x = 2:3

40*3/2 = x

x = 60 minutes

Therefore it will take total 90 minutes to finish the book and 60 minutes to read the left 40 pages.
