Answer: x° is 50°

Step-by-step explanation: The sum of the exterior angles of a polygon is 360.

Add the given exterior angles:

35+50+20+125=230

to find the missing exterior angle, supplementary to x°,

Subtract 360 - 230 = 130

The Sum of Supplementary angles is 180°

x° + 130° = 180°

x = 50

The contents of seven similar containers of sulfuric acid are 9.8, 10.2, 10.4, 9.8, 10.0, 10.2, and 9.6 liters. find a 95% confi
Kamila [148]
The confidence interval is from 9.81 to 10.19.

We first find the mean of the data:

<span>(9.8+10.2+10.4+9.8+10.0+10.2+9.6)/7 = 10

Next we find the standard deviation:
</span>σ=√([<span>(9.8-10)^2+(10.2-10)^2+(10.4-10)^2+(9.8-10)^2+(10-10)^2+(10.2-10)^2+(9.6-10)^2]/7) = 0.262

The z-score for 95% confidence is found by
1-0.95 = 0.05; 0.05/2 = 0.025; from the z-table, it is 1.96.

The confidence interval is calculated using
</span>x\pm z\times (\frac{s}{\sqrt{n}})&#10;\\&#10;\\10 \pm 1.96(\frac{0.262}{\sqrt{7}})=10\pm 0.1941<span>

Help me with inequality
Hoochie [10]

Answer:

  C.  x > 3

Step-by-step explanation:

As long as you don't multiply or divide by any negative numbers*, <em>you can solve this the same way you would an equation</em>.

  3x +2 > x +8

  3x > x +6 . . . . . . subtract 2

  2x > 6 . . . . . . . . subtract x

  x > 3 . . . . . . . . . .divide by 2; matches choice C

_____

* The complete rule is "as long as you don't use any order-changing operations, ...". There are some functions you can apply to both sides of the inequality that will change the ordering. Multiplication or division by a negative number is only one of many.

  1 < 2

  -1 > -2 . . . . . multiplication by -1 reverses the order

Y = 5x - 13<br><br> 4x + 3y = 18
hram777 [196]
<span>replace Y = 5x - 13
into
4x + 3y = 18

</span>

4x + 3 (5x - 13) = 18
4x + 15 - 39 = 18
4x -24 = 18
4x = 18 +24
4x = 42
x = 42/4
x = 10.5

Y = 5(10.5) - 13
=  52.5 - 13
= 39.5

answer: x = 10.5 and y = 39.5

Bill and Joe have 60 dollars between them. Bill has half as much as Joe. How much does Bill have?
Katyanochek1 [597]
Bill and Joe have 60 dollars between them. Bill has half as much as Joe.

so Bill = B and Joe = J

20 (B) + 40 (J) = 60

Bill has half the amount of Joe, and so 40/2  = 20

subtract 60 from 20 (the answer for Bill) and you get 40, (the answer for Joe)

hope this helps
