3n^2-1 find the 2nd and 5th term

Answers

Answer:

2nd term = 11

5th term = 74

Step-by-step explanation:

3n² - 1

n = 2 , 2nd term = 3*2²  - 1

                           = 3*4 -1

                          = 12 - 1

                          = 11

n= 5 , 5th term = 3*5² - 1

                        = 3*25 - 1

                      = 75 - 1

                      = 74

Step-by-step explanation:

in[tex]\tt{3n^2-1 }[/tex] ⠀

If n=2

What happens to the mean of the data set {10, 2, 8, 9, 5, 2, 6} if the number 12 is added to the data set? A. The mean increases by 2. B. The mean increases by 12. C. The mean increases by 0.75. D. The mean increases by 1.75.

Answers

Answer:

C. The mean increases by 0.75.

Step-by-step explanation:

The mean of a data set is given by the sum of all its values, divided by the number of values.

Data set {10, 2, 8, 9, 5, 2, 6}

7 values

Sum: 10 + 2 + 8 + 9 + 5 + 2 + 6 = 42

Mean: 42/7 = 6

Adding number 12 to the data set

Now we have 8 values

The sum is 42 + 12 = 54

The mean is 54/8 = 6.75

This means that the mean increases by 0.75.

Answer:

C. 7.5

Step-by-step explanation:

the mean increases by it

Here a easy one tooooooooooooo

Answers

Remember:
A triangle is always 180 degrees and so is a straight line so 360 degrees in total:

1) Add 92 and 123 which equals 215
Then 360 subtracted by 215 is 145

Answer: 145

2) add 100 and 25= 125
360-125= 235
Answer: 235 degrees

Answer: See explanation

Step-by-step explanation:

1.) There's an angle supplementary to m∠123°, that angle is y

y and m∠123° are supplementary since they're linear pairs

y + 123 = 180

Subtract both sides by 123

y = 57°

Now we know at least two angles of the triangle, x + y + m∠92° has to be 180° because they form a triangle.

x + y + m∠92° = 180°

x + 57 + 92 = 180

x + 149 = 180

Subtract both sides by 149

x = 31°

2.) We have to figure out the missing angle in the triangle, that missing angle is once again, y.

y + 100 + 25 = 180

y + 125 = 180

y = 55°

x and y are supplementary angles because they form a straight line

x + y = 180°

x + 55 = 180

Subtract both sides by 55

x = 125°

The model of a shopping mall is made using a scale of 1: 50
If the model of the house is 40 cm tall, calculate the height of the
house in metres.​

Answers

Answer:

20 m

Step-by-step explanation:

Given that :

Scale of 1 : 50 is used to make a model

If the model has a height of 40 cm ; the height of the house is:

Then, the actual height of the house is (40 * 50) = 2000 cm

Thus the height of the house in metre is :

100cm = 1 meter

2000 cm = 2000 / 100

2000 cm = 20 meter

Height of house in meter = 20 meter

Answers

Answer:

UY = 90

GH = 4

Step-by-step explanation:

Since both figures are similar, the ratio of their corresponding side lengths would be the same.

Thus:

✔️UY/GF = XW/IJ

UY/10 = 54/6 (Substitution)

Multiply both side by 10

UY = (54*10)/6

UY = 90

✔️Also,

UV/GH = XW/IJ

36/GH = 54/6

36/GH = 9

GH = 36/9

GH = 4
