Answer:

6x + 7 = 8

Step-by-step explanation:

Let x represent the unknown number.

Translating the word problem into an algebraic expression, we have;

6x + 7 = 8

To find the value of x;

6x = 8 - 7

6x = 1

x = 1/6

<h3>Further explanation </h3>

Angles can be formed from two ray lines that have the same starting point

Commonly used terms include foot angle, corner point, and angle size

The magnitude of the angle is usually expressed in degrees

Naming angles can be with one letter according to the vertex or with three letters with the vertex placed between two other letters

There are several steps used to copy the MNP angle:

1. Draw the DE line

2.Places the compass point on point N and draws an arc that intersects NM (point Q) and NP (Point R)

3.Without changing the compass opening, put the compass point on point D and draw a long arc that intersects DE (point F)

4. Open the compass so that the compass point is on point Q and the pencil point is on point R. Then put the compass point on point F and draw an arc (intersect with the arc in step 3, and at this point we name it G)

5. Draw a line from point D to point G

Then the MNP is congruent to the EDG

Consider randomly selecting a student at a large university, and let A be the event that the selected student has a Visa card an

ziro4ka [17]

Answer:

1) is not possible

2) P(A∪B) = 0.7

3) 1- P(A∪B) =0.3

4) a) C=A∩B' and P(C)= 0.3

b) P(D)= 0.4

Step-by-step explanation:

1) since the intersection of 2 events cannot be bigger than the smaller event then is not possible that P(A∩B)=0.5 since P(B)=0.4 . Thus the maximum possible value of P(A∩B) is 0.4

2) denoting A= getting Visa card , B= getting MasterCard the probability of getting one of the types of cards is given by

P(A∪B)= P(A)+P(B) - P(A∩B) = 0.6+0.4-0.3 = 0.7

P(A∪B) = 0.7

3) the probability that a student has neither type of card is 1- P(A∪B) = 1-0.7 = 0.3

4) the event C that the selected student has a visa card but not a MasterCard is given by C=A∩B' , where B' is the complement of B. Then

P(C)= P(A∩B') = P(A) - P(A∩B) = 0.6 - 0.3 = 0.3

the probability for the event D=a student has exactly one of the cards is

P(D)= P(A∩B') + P(A'∩B) = P(A∪B) - P(A∩B) = 0.7 - 0.3 = 0.4
