Answer:

arc\ DBE=206^o

Step-by-step explanation:

The picture of the question in the attached figure

<u><em>The question is</em></u>

Find the measure of arc DBE          

step 1

Find the value of k

we know that

m\angle EPC=90^o ----> by quarter of circle

m\angle EPC=(33k-9)^o

so

(33k-9)^o=90^o

solve for k

33k=90+9\\33k=99\\k=3

step 2

Find the measure of angle DPC

we know that

m\angle DPC=(20k+4)^o

substitute the value of k

m\angle DPC=(20(3)+4)=64^o

step 3

Find the measure of angle BPD

we know that

m\angle BPD+m\angle DPC=90^o ---> by complementary angles

substitute the given value

m\angle BPD+64^o=90^o

m\angle BPD=90^o-64^o=26^o

step 4

Find the measure of arc DBE

we know that

arc\ DBE=arc\ DB+arc\ BAE

arc\ DB=m\angle BPD=26^o ----> by central angle

arc\ BAE=180^o ---> because a diameter divide the circle into two equal parts (BE is a diameter)

substitute

arc\ DBE=26^o+180^o=206^o

Which is a solution to the equation 6 x + y = 4<br><br>1, -10 <br>2, -8<br>2, 8<br>1, 2
NISA [10]

Answer:

1,-10 and 2,-8

Step-by-step explanation:

If you substitute each answer choice:

6+-10=4

12+-8=4

12+8=4

6+2=4

The only ones that would make sense are the first and second one.

Suppose we have 3 cards identical in form except that both sides of the first card are colored red, both sides of the second car
Nikolay [14]

Answer:

probability that the other side is colored black if the upper side of the chosen card is colored red = 1/3

Step-by-step explanation:

First of all;

Let B1 be the event that the card with two red sides is selected

Let B2 be the event that the

card with two black sides is selected

Let B3 be the event that the card with one red side and one black side is

selected

Let A be the event that the upper side of the selected card (when put down on the ground)

is red.

Now, from the question;

P(B3) = ⅓

P(A|B3) = ½

P(B1) = ⅓

P(A|B1) = 1

P(B2) = ⅓

P(A|B2)) = 0

(P(B3) = ⅓

P(A|B3) = ½

Now, we want to find the probability that the other side is colored black if the upper side of the chosen card is colored red. This probability is; P(B3|A). Thus, from the Bayes’ formula, it follows that;

P(B3|A) = [P(B3)•P(A|B3)]/[(P(B1)•P(A|B1)) + (P(B2)•P(A|B2)) + (P(B3)•P(A|B3))]

Thus;

P(B3|A) = [⅓×½]/[(⅓×1) + (⅓•0) + (⅓×½)]

P(B3|A) = (1/6)/(⅓ + 0 + 1/6)

P(B3|A) = (1/6)/(1/2)

P(B3|A) = 1/3
