Answer:

4 5 9

11 6 1

3 7 8

Step-by-step explanation:

In a magic square, all rows, columns, and diagonals have the same sum.

Let's call the cells a - i this way:

a b c

d e f

g h i

Now lets's fill in what we have:

a b 9

11 6 1

g h i

2nd row: 11 + 6 + 1 = 18

3rd column: 9 + 1 + i = 18; i = 8

a b 9

11 6 1

g h 8

Main diagonal: a + 6 + 8 = 18; a = 4

4 b 9

11 6 1

g h 8

1st row: 4 + b + 9 = 18; b = 5

4 5 9

11 6 1

g h 8

1st column: 4 + 11 + g = 18; g = 3

4 5 9

11 6 1

3 h 8

2nd column: 5 + 6 + h = 18; h = 7

4 5 9

11 6 1

Answer:

Step-by-step explanation:

So you can see the 5 pattern, so you add 9+5= 14 which goes in the middle square and 14+5=18 in the left square

Now between 18 and 11 it is 7 so you subtract 7 which equals 4 then - 5= -1 then -5= -6

Suppose the p-value is 0.1038. what is the correct interpretation of this p-value in context?

Basile [38]

The p value 0.1038 represent the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.

According to the statement

we have given that the P value and we have to find the correct interpretation of this p-value in context.

So, For this purpose, we know that the

The P - Value is the In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed.

And in the given statement ,

The given p value is 0.1038.

And this p value is a If the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.

So, The p value 0.1038 represent the proportion of students who use drugs at this college is equal to 0.157, the probability of getting a statistic as extreme or more extreme as that observed is 0.1038.

A train normally travels 240 km at a certain speed. One day, due

Marrrta [24]

$\large\bf{\underline\red{Good \: Afternoon♡}}$

Normal-travel DATA:

distance = 240 km

rate = x km/h

time = d/r

= 240/x hrs

_______________________

Bad weather DATA:

distance = 240 km

rate = (x-20) km/h

time = 240/(x-20) hrs

______________________

Bad time - normal time = 2 hrs

240/(x-20) - 240/x = 2

120/(x-20) - 120/x = 1

120x -120(x-20) = x(x-20)

20 = x^2 -20x

x^2 - 20x - 20 = 0

x = [20 +- sqrt(20^2 - 4*1*-20)]/2

x = [20 +- sqrt(480)]/2

x = [20 +- 4sqrt(30)]/2

x = 10 +- 2sqrt(30)

The mean length of six-year-old rainbow trout in the Arolik River in Alaska is 481 millimeters with a standard deviation of 41 m

Bezzdna [24]

Answer: 0.688

Step-by-step explanation:

Given: Mean : $\mu = 481 \text{ millimeters}$

Standard deviation : $\sigma=871\text{ millimeters}$

Sample size : $n=1600$

We assume these lengths are normally distributed.

Then the formula to calculate the z score is given by :-

$z=\dfrac{X-\mu}{\sigma}$

For X=501

$z=\dfrac{501-481 }{41}=0.487804878049\approx0.49$

The p-value of z = $P(z$

Now, the probability of the newborns weighed between 1492 grams and 4976 grams is given by :-

Hence, The proportion of six-year-old rainbow trout are less than 501 millimeters long = 0.688
