Find the value of x and y

Mathematics
1 answer:
Kryger [21]2 years ago
5 0

Answer:

Supplementary to x is a 90° angle (right angle) which means that both x and the right angle will have to equal 180 degrees:

90 + x = 180

-90        -90

x = 90°

Let's find the angle measure that is supplementary to y.

A 5 sided shape is equal to 540 degrees (you could find this by using the formula: (n - 2) x 180 where n is the number of sides)

so given interior angles:

90 + 80 + 98(supplementary to angle 82 degrees) + 136 + 136(two equal angle measures in the polygon that are missing)

= 540(which is correct), so now we know the two missing angles, 136, besides the angle supplementary to 82 degrees.

136 is supplementary to y so:

136 + y = 180

-136       -136

y = 44°

Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews
maks197457 [2]

Answer:

Step-by-step explanation:

The given information can be tabulated as follows.

Success type          High             Moderate              Low            Total

                                 0.40                   0.35                 0.25             1

Good reviews          0.95                    0.60                0.10

Combined prob       0.4*0.95             0.35*0.6          0.25*0.1

                                 0.38                    0.21                  0.025       0.6125

A) the probability that  a product attains a good review

=Prob it it successful and gets good review + Prob it  is moderate successful and gets good review +Prob it it low successful and gets good review

= 0.6125

B) If a new design attains a good review,  the probability that it will be a highly successful product= \frac{0.38}{0.6125} \\=0.6204

C) Prob that does not attain a good review =(0.40*0.05)+0.35(0.4) +(0.25)*0.9

= 0.385

Prob for successful not getting good review = 0.40(0.05) = 0.02

Reqd prob = \frac{0.02}{0.385} \\=0.05195

“How did Faulkner pull it off?” is a question many a fledgling writer has asked themselves while struggling through a period of apprenticeship like that novelist John Barth describes in his 1999 talk "My Faulkner." Barth “reorchestrated” his literary heroes, he says, “in search of my writerly self... downloading my innumerable predecessors as only an insatiable green apprentice can.” Surely a great many writers can relate when Barth says, “it was Faulkner at his most involuted and incantatory who most enchanted me.” For many a writer, the Faulknerian sentence is an irresistible labyrinth. His syntax has a way of weaving itself into the unconscious, emerging as fair to middling imitation.

While studying at Johns Hopkins University, Barth found himself writing about his native Eastern Shore Maryland in a pastiche style of “middle Faulkner and late Joyce.” He may have won some praise from a visiting young William Styron, “but the finished opus didn’t fly—for one thing, because Faulkner intimately knew his Snopses and Compsons and Sartorises, as I did not know my made-up denizens of the Maryland marsh.” The advice to write only what you know may not be worth much as a universal commandment. But studying the way that Faulkner wrote when he turned to the subjects he knew best provides an object lesson on how powerful a literary resource intimacy can be
