Answer:

x = 86

Step-by-step explanation:

<em>note</em> <em>: a straight line is regarded to have an angle of 180 degrees.</em>

in this case CUW is a straight line

I shall show you two methods . which ever one you choose will still get the same answer. however understanding both will help you use them for other questions

<h3><em><u>method 1 </u></em></h3>

therefore in order to solve the value of x we need to get the missing angle in the triangle first which is angle WUV

<h3 /><h3><u>Angle WUV</u></h3>

notes : a triangle has a total angle of 180 degrees

hence we can create an equation to get the angle WUV

lets make the missing angle as <u> Y ,</u> this will help to find the answer.

46 + Y + 40 = 180

now make Y the subject of formula

Y = 180 - 40 - 46

now in order to find x .

since the CUW is a straight line with 180 degrees

hence x = 180 - 94 = 86

<h3><u>x = 86</u></h3><h2 /><h2><em><u>method 2</u></em></h2>

since the triangles total angle is 180 degrees and also the straight line is also 180 degrees. we can just add the total of the 2 sides of the triangle ( the two interior angles can be added together to get the value of the exterior one)

40 + 46 = 86

A population mean of 360, a standard deviation of 4, and a margin of error of 2.5%

Ad libitum [116K]

Answer:

(351.04, 368.96)

Step-by-step explanation:

Given that population mean= 360

Std devitaion = 4

margin of error = 2.5%= 0.025

Since population std deviation is known we can use Z critical value

For two tailed critical value for 2.5% would be

2.24

Margin of error = ±Critical value*std deviation

= ±2.24(4)

= ±8.96

Confidence interval =(Mean - margin of error, mean + margin of error)

= $(360-8.96, 360+8,.96)\\= (351.04, 368.96)$

Help?. . What is the equation of the function y=5/x translated 4 units to the left and 3 units up?. . I don't even know where to

Dahasolnce [82]

Y = 5/x
If you want to shift the function 4 units left, you can add 4 to the x-value in the parent function:
y = 5 / ( x + 4 )
After that, you can add 3 to your function to shift it up 3 units.
y = 5 /( x + 4 ) + 3 ( the final equation )

The cost of a compact disc is $18. Mrs. Meridth bought 3 discs and received a 15% discount. If the sales tax is 8.8%, find the t

Harlamova29_29 [7]

Answer:

$49.572

Step-by-step explanation:

Given that :

Cost per disc = $18

Number of disc purchased = 3

Discount received = 15%

Sales tax = 8%

Original cost : cost per dic * number purchased

Original cost = $18 * 3 = $54

Discounted price = (100 - 15)% * $54

Discounted price = $45.9

Sales tax :

(100 + 8)% of $45.9

108% * $45.9

= $49.572

Total price = $49.572

Answer:

The answer would be A/B=H

Step-by-step explanation:

To get rid of the B that is connected to the H, you would do the opposite of what they used. Meaning since the two were multiplied you would divide them. So, you would take your b and divide it on both sides of the equal sign. B and B cancels each other out so you are left with A/B which equals H.

A technology company determined that an average of 3 phones were defective for every 200 phones it produced. At this rate, about

Anit [1.1K]

You have to calculate the probability for the given average:
= 3/200 = 0.015 = 1.5%
For 50,000 phones you have to multiply the probability by 50,000:
0.015*50,000 = 750 phone defectives if the company produced 50,000
