If the mean is 4, what is the missing number of the data set: 3, 4, ___, 7, 2, 1.

Answers

Answer 1

Answer:

7

Step-by-step explanation:

Let the missing number of the data be x.

[tex] \because mean = \frac{3 + 4 + x + 7 + 2 + 1}{6} \\ \\ \therefore 4 = \frac{17 + x }{6} \\ \\ \therefore 4 \times 6 = 17 + x \\ \\ \therefore 24 - 17 = x \\ \\\therefore x = 7[/tex]

Thus, the missing number of the data is 7.

Answers

Answer:

82.7

Step-by-step explanation:

Answer: the answer is that the mean would become smaller.

Step-by-step explanation: if you have the original 9 values, the mean is 85.5 repeating. Adding 65 and 75 to the data set changes the mean to 82.72 repeating.

Answers

Answer:

5 7/12 but it's 67/12 as an improper fraction

Step-by-step explanation:

4 3/12 + 1 4/12

First add the fractions:
Because they have the same denominator, you won’t have to change anything.

Add the numerators:
3+4= 7 So... 7/12

Now the whole numbers:
1+4=5

Put the two together:
5+7/12= 5 7/12

Answer: 5 7/12


Which BEST describes the association between goals by the Red Team and the Blue Team?
A
nonlinear association
B
positive association
С
no association
D
negative association

Answers

b positive association

The relation between the Red team and Blue team will be a non-linear association. Then the correct option is A.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The table is shown below.

The association between the goals of the Red Team and the Blue Team will be given in the table.

Let the line passes through the point (1, 1) and (4, 9). Then we have

y - 1 = 8/3(x - 1)

y - 3 = 8x - 8

    y = 8x - 5

But all the points present between the (1, 1) and (4, 9) do not lie on the line. Then the relation between the Red team and the Blue team will be a non-linear association.

More about the linear system link is given below.

5. Find the perimeter and area of the parallelogram. Round to the nearest tenth if necessary.

Answers

Answer:

perimeter: 23.6yd

area: 34.3yd²

Step-by-step explanation:

This is technically a rectangle, but alrighty, so for the perimeter, you just add all the sides together, or multiply, blah blah blah, no here:

5.2 x 2 + 6.6 x 2 = 23.6

So the perimeter is 23.6yd

Now, we find the area by multiplying the width by the height (i think that's the right terminology, so you basically just multiply the only number's there:

5.2 x 6.6 = 34.32

But then we round to the tenth and 2 rounds down to 34.3, so the area is 34.3yd²

hope this helps:)

If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by y = 56t − 1.86t2.
(a) Find the average speed over the given time intervals.
(i) [1, 2] m/s
(ii) [1, 1.5] m/s
(iii) [1, 1.1] m/s
(iv) [1, 1.01] m/s
(v) [1, 1.001] m/s
(b) Estimate the speed when t = 1. m/s.

Answers

Answer: (a) (i)50.42 m/s (ii) 51.35 m/s (iii) 52.094 m/s (iv) 52.2614 m/s (v) 52.27814 m/s

(b) 54.14 m/s

Step-by-step explanation:

The average speed over the given time interval [a,b]: = [tex]\frac{y(b)-y(a)}{b-a}[/tex]

Given: If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by [tex]y = 56t − 1.86t^2.[/tex]

(a)

(i) average speed = [tex]\frac{y(2)-y(1)}{2-1}[/tex]

[tex]=\frac{56(2)-1.86(2)^2-(56(1)-1.86(1)^2)}{1}[/tex]

[tex]=50.42[/tex] m/s

(ii) average speed = [tex]\frac{y(1.5)-y(1)}{1.5-1}[/tex]

[tex]=\frac{56(1.5)-1.86(1.5)^2-(56(1)-1.86(1)^2)}{0.5}[/tex]

[tex]=51.35[/tex]m/s

(iii) average speed = [tex]\frac{y(1.1)-y(1)}{1.1-1}[/tex]

[tex]=\frac{56(1.1)-1.86(1.1)^2-(56(1)-1.86(1)^2)}{0.1}[/tex]

[tex]=52.094[/tex]m/s

(iv) average speed = [tex]\frac{y(1.01)-y(1)}{1.01-01}[/tex]

[tex]=\frac{56(1.01)-1.86(1.01)^2-(56(1)-1.86(1)^2)}{0.01}[/tex]

[tex]=52.2614 [/tex]m/s

(v) average speed = [tex]\frac{y(1.001)-y(1)}{1.001-01}[/tex]

[tex]=\frac{56(1.001)-1.86(1.001)^2-(56(1)-1.86(1)^2)}{0.001}[/tex]

[tex]=52.27814 [/tex]m/s

(b) [tex]y(1)=56(1)-1.86(1)^2[/tex]
