So you just need to use the crocodile signs < or >
As j is less than 113 we put j on the smaller side and 113 on the bigger side to make:
j<113

Alja [10]

Answer:

1) the number of hours of TV watched

2)  quantitative

3) Mean or Median

Completed details of Question

Additional details to the question are as below

1) Identify the variable measured on each student.

2) Is the variable categorical or quantitative?

3) Identify two statistics that the student could use to summarize the variable.

a) Mean or Median

b) Mean or Proportions

c) Mean or Mode

d) Median or Mode.

Explanation to the answer:

1) The variable measured on each student is the number of hours of TV watched

2) The variable is the amount of time, therefore it is quantitative.

3)  Quantitative data can be used compare the exact size and extent of difference in two quantities. Therefore, the two statistics that the student could use to summarize the variables would be Mean or Median. Mean will be the average time and Median will be the middle when the amount of time is ordered from least to greatest.

PLEASE HELP!!
aev [14]

Answer:

D. No, because P(A|B)=0.22 and the P(A) = 0.53 are not equal.

Step-by-step explanation:

Given:

Probability of doing yard work is, P(A)=53\%=0.53

Probability of raining, P(B)=68\%=0.68

Probability of doing yard work and it raining is, P(A\cap B)=15\%=0.15

Now, two events A and B are independent if,

P(A|B)=P(A);P(B|A)=P(B)

Conditional probability of event A given that B has occurred is given as:

P(A|B)=\frac{P(A\cap B}{P(B)}\\P(A|B)=\frac{0.15}{0.68}=0.22

So, P(A|B)=0.22\ and\ P(A)=0.53

Since, P(A|B)\ne P(A), A and B are not independent events.

It’s answer C. You multiply 8 & 13, which will give you 104. Then, multiply 8 & 2y, which will also give you 16y.

Solve for X <br><br> PLEASE HELP DUE IN 10 MINS
ziro4ka [17]

Answer:

x = 8

Step-by-step explanation:

The measures of the angles in a triangle add up to equal 180°

That being said we can create an equation to solve for x

( note that this is a right triangle indicated by the square. A right triangle has a right angle which has a measure of 90° )

180 = 90 + 5x + 5 + 5x + 5

now we solve for x using basic algebra

step 1 combine like terms

90 + 5 + 5 = 100

5x + 5x = 10

now we have 180 = 100 + 10x

step 2 subtract 100 from each side

180 - 100 = 80

100 - 100 cancels out

now we have 10x = 80

step 3 divide each side by 10

10x / 10 = x

80 / 10 = 8

we're left with x = 8
