Can someone please help me?

Answers

Hello,

$u_(1) =2\n u_(2) =2+6\n u_(3) =2+2*6\n u_(4) =2+3*6\n...\n u_(n) =2+(n-1)**6\n u_(30) =2+29*6=176\n$

Answer B

So first u have to find the nth term, here the nth term is : 6n-4
Then replace the n with term that u want so:
6(30) - 4
= 180-4
=176
So it's B

When flying from Florida to the Philippines island why does the shortest route pass through Alaska?

Answers

Because the earth is round, the distance seen on a flat map is a lot further than the distance on a globe, because of distortion. So following the circle that goes through these 3 points ( Florida, Alaska and the Philippines) it is a shorter distance to fly over Alaska.

5 . Which is the box-and-whisker plot for the data set?

Answers

Answer with explanation:

Ques 1)

We know that the range of a data set is the difference between the maximum and the minimum value.

We are given a data set as:

45 93 60 72 15 45 81

on arranging the data in the increasing order we get:

15 45 45 60 72 81 93

Minimum value=15

Maximum value=93

Range=Maximum value-Minimum value

Range=93-15

Range=78

Ques 2)

We are given data point as:

63 54 62 59 52

on arranging the data in the increasing order we have:

52 54 59 62 63

The mean of data is calculated as:

$Mean=(52+54+59+62+63)/(5)\n\n\nMean=(290)/(5)\n\n\nMean=58$

Now we calculate variance

Let mean be denoted by x'

x-x' (x-x')²

52-58= -6 36

54-58= -4 16

59-58=1 1

62-58=4 16

63-58=5 25

∑ (x-x')²=94

Now, variance is:

Variance=∑ (x-x')²/5

=94/5

= 18.8

Hence, variance is: 18.8

Ques 3)

We are given Variance=88

As standard deviation is the square root of variance.

Hence,

standard deviation=√88

=9.38

Ques 4)

We arrange the data in the increasing order as:

4 4 5 5 5 6 9

Now mean of the data is:

$Mean(x')=(4+4+5+5+5+6+9)/(7)\n\n\nMean=(38)/(7)\n\n\nMean(x')=5.43$

(x-x') (x-x')²

-1.43 2.04

-0.43 0.18

0.57 0.32

3.57 12.74

∑ (x-x')²/7=17.68/7=2.52

Hence Variance=2.52

Now standard deviation is the square root of variance.

Hence standard deviation=√2.52=1.6

Ques 5)

The box and whisker plot is attached to the answer.

Minimum value=6

Maximum value=21

Median=14

First quartile=9

Upper quartile=17

1. The largest number subtract the smallest number. So it would be 93-15=78
