Students who attend Anytown College pay either in-state or out-of-state tuition, depending on where they reside. The mean and st

netineya [11]

Answer:

For a pair of randomly selected in- and out-of-state students, the sum of their tuition typically varies from the mean of $6,348.75 by about $1,508.48.

Step-by-step explanation:

Given

$\mu S = \$6,348.75$

$\sigma S = \$1,508$

Required

Interpret the standard deviations

In statistic, standard deviation is a measure of how the given data lies away (or varies) from the mean.

This implies that:

For the in-state students, the standard deviation measures how the sum of their tuition varies from 6348.75

For the out-state students, the standard deviation measures how the sum of their tuition varies from 1508

What is the 50th term of the arithmetic sequence 3, 7, 11, 15, ... ?

zysi [14]

Answer:

B. 199

Step-by-step explanation:

We are given an Arithmetic sequence : 3, 7, 11, 15, ...

We are supposed to find the 50th term .

So, first consider the formula of nth term in Arithmetic mean:

$a_{n} = a+(n-1)*d$

where

a is first term of sequence

n is term position

d is common difference

$a_{n}$ = the term you are supposed to find

Now,

a = 3 ( first term )

n = 50 th term ( given )

d = 7-3 = 11-7 = 4(common difference

Substitute these value in the formula given above

⇒ $a_{50} = 3+(50-1)*4$

⇒ $a_{50} = 3+(49)*4$

⇒ $a_{50} = 3+196$

⇒ $a_{50} = 199$

Hence ,The 50th term of given arithmetic sequence is 199

So, OPTION B is correct .

Answer:

acute scalene triangle

Step-by-step explanation:

The largest angle is acute, and all sides are different lengths. The triangle is an acute scalene triangle.

____

The magnitudes of the coordinate differences are ...

WX = (7, 5), XY = (2, 7), WY = (9, 2)

The two sides that are closest in length are ...

WX = √(49+25) = √74

WY = √(81 +4) = √85

Obviously, these are different lengths.

You can get a clue by comparing the numbers whose squares you are adding:

7^2 +5^2 > 7^2 +2^2 . . . . . WX > XY

9^2 +2^2 > 7^2 +2^2 . . . . WY > XY

so, the only question is relation between WX and WY. We note that the length of WX is less than one of the coordinate differences of WY, so we know WY is the longest. (√74 < 9)

We can tell from the graph that angle X (opposite longest side WY) is an acute angle, so the triangle is acute.
