Answer:

I think the answer to this question is adjacent

Step-by-step explanation:

Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.

A cathedral has a large,circular stained glass window. A visitor measures the window and calculates that it has a circumference

vichka [17]

First, we find the diameter.
12.56 divided by 3.14 = 4.
Next, find the radius.
4 divided by 2 = 2.
Then, use the formula to calculate the area.
2 times 2 times 3.14 = 12.56 is your area.
In this case, the area and the circumference are the same. Sometimes that is not that case though. Hope it helps! :)

A diamond can be classified as either gem-quality or industrial-grade. 80% of diamonds are classified as industrial-grade.

mote1985 [20]

Answer:

a) 0.64

b) 0.21

c) 0.79

Step-by-step explanation:

Percentage of industrial-grade diamonds = 80%

This means, if one diamond is chosen at random, there is 80% chance that it will be of industrial-grade. So,

P(Industrial grade) = 80% = 0.80

Part a)

Probability that 1st diamond is industrial-grade = 0.80

Since, selection of diamonds in independent, the probability that 2nd diamond is also industrial grade = 0.80

The overall probability of both diamonds being industrial-grade will be the product of their individual probabilities, according to the fundamental rule of counting.

So, if two diamonds are chosen at random, the probability that both are industrial grade = 0.80 x 0.80 = (0.80)² = 0.64

Part b)

Following the same logic as we followed in the previous part.

The probability of each of the 7 diamonds being industrial-grade is 0.80, so the probability that all 7 are industrial grade will be:

Probability = 0.80 x 0.80 x 0.80 x 0.80 x 0.80 x 0.80 x 0.80 = $(0.80)^{7}$ = 0.21

So, if 7 diamonds are chosen at random, the probability that all 7 are industrial grade is 0.21.

Part c)

The event "at least one" is complement of event "none". So, the event "at least one of 7" will be complement of "none of the 7"

If none of the selected diamonds is gem quality, this means all 7 of the diamonds are industrial-grade. So,

The probability that none of the diamonds is gem-quality = The probability that all 7 are industrial-grade = 0.21

So,

The probability that at least one of the 7 selected diamonds is gem-quality = 1 - Probability that none is gem-quality

= 1 - 0.21

= 0.79

Since the probability that atleast one of the 7 randomly selected diamonds is gem-quality is greater than 0.05, it won't be unusual event.

Find the value of x , then find the measure of angle A ( show your work ).

MakcuM [25]

Step-by-step explanation:

2x+2+6x+4=120°(exterior angle of a triangle is equal to the sum of its opposite interior angle)

8x+6=120

8x=120-6

8x=114

x=114/8

x=14.25

now,

angleA=2x+2

2×14.25+2
28.5+2
30.5°

hope it helps.

If you select one card at random from a standard deck of 52 cards, what is the probability that the card is a five AND a club?

horsena [70]

Probability is expressed as

number of favorable outcomes/number of total outcomes

The number of cards in a deck is 52(total outcomes)

Recall, there is only 1 five of clubs in a deck of cards(favorable outcomes)

Thus, the probability that the card is a five AND a club is 1/52
