Answer:

m∠y=50°

m∠x=50°

Step-by-step explanation:

we know that

The angles in matching corners are called <u><em>corresponding angles</em></u>. When the two lines are parallel Corresponding Angles are equal

so

m∠y=50° -----> by corresponding angles

and

The angles that are formed on opposite sides of the transversal and inside the two lines are <u><em>alternate interior angles</em></u>. When the lines are parallel, the alternate interior angles are equal.

so

m∠x=m∠y -----> by alternate interior angles

so

m∠x=50°

therefore

m∠y=50°

m∠x=50°

A mechanical engineer wishes to compare strength properties of steel beams with similar beams made with a particular alloy. The
Annette [7]

Answer:

50

Step-by-step explanation:

Level of significance, a = 0.01

Type II error probability, b =0.05

From the z-table:

the critical value at 1% level of significance, Zα = Z0.01 = 2.33

the critical value at 5% probability, Zβ = Z0.05 = 1.645

The critical value of z can be obtained from the standard normal table using the desired level of significance and the tail of test.  

The critical value tells the number of standards deviations away is the result from the mean.

Probability of type I error denoted by  a

Probability of type II error denoted by b.

Type I error is to falsely infer the existence of something that is not there, while a type II error is to falsely infer the absence of something that is.

From the given information,

a=0.01, b=0.05, o1 = o2 =0.05, Dο = 0, D' = 0.04

The sample size is calculated as,

n = ( o^2 + o2^2) * (Za +Zb)^2 /( (D' - D0)^2)

= (0.05^2 +0.05^2)*(2.33 + 1.645)^2 / (0.04 - 0)^2

= 49.38

which is 50 [Rounded to next integer]

: lCompare and contrast the rules for Adding and Subtracting positive andnegative numbers to the rules for Multiplying and Divid
Oksanka [162]

The rules of adding and subtracting positive and negative numbers include

1) When we add 2 positive numbers, the result is a positive number

2) When we subtract 2 positive numbers, the result would be positive as long as a smaller number is being subtracted from a bigger number, otherwise, the result would be negative

3)When we add 2 negative numbers, the result can be positive if we add the negative number to a bigger positive number or the result would be negative if we add the negative number to a lower positive number

4)When we subtract 2 negative numbers, the result is always negative

The rules of multiplying and dividing positive and negative numbers include

1) When we multiply 2 positive numbers, the result is always positive

2) When we multiply 2 negative numbers, the result is always positive

3) When we divide 2 positive numbers, the result is always positive

4) When we divide 2 negative numbers, the result is always positive

5) When we multiply or divide a positive number by a negative number, the result is always negative.

Which missing side length makes the perimeter , p = 26 feet true?
Anastaziya [24]
If the width is 3 on each side, that is 3 + 3 = 6. 
26 - 6 = 20. 
There are two sides left: 20 divided by 2 = 10. 
10+10+3+3 = 26.
The length is 10.
