Answer:
1083 seats
Step-by-step explanation:
this is an arithmetic sequence :
an = an-1 + c
in our case
a1 = 10 (10 seats in the first row)
a2 = a1 + 1 = 10 + 1 = 11
a3 = a2 + 1 = a1 + 1 + 1 = 10 + 1 + 1 = 12
an = an-1 + 1 = a1 + (n-1)×1 = a1 + n - 1 = 10 + n - 1 = 9 + n
a38 = a1 + 37 = 10 + 37 = 47 seats.
altogether this means the sum of the arithmetic sequence of a1 to a38.
the general sum of an arithmetic sequence from a1 to an is
n×(a1 + an)/2
in our case
38×(10 + 47)/2 = 19×57 = 1083 seats
A linear equation in the form y = mx + c has slope m Any line parallel to 3x + 9y = 5 has the same slope 3x + 9y = 5 → 9y = -3x + 5 → y = (-3/9)x + 5/9 → y = -⅓x + 5/9 & So it’s 10 and 0
Answer:
Options 1,2,6,7 are correct statements.
Step-by-step explanation:
In the given figure lines m and n are cut by a transversal t.
Among all the statements the options that are correct are :
1)<1 and <5 are corresponding angles.(The angles in matching corners are called corresponding angles)
2)<3 and <6 are alternate interior angles .(The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles)
6)<4 and <6 are same side consecutive angles.(consecutive angles lie on the same side of the transversal)
7)<1 and <8 are alternate exterior angles.( These angles lie on the exterior side of the lines and on opposite side of the transversal)

Answer:
Step-by-step explanation:
Given:
Number of questions (N) = 16
Number of easy questions (E) = 8
Number of medium-hard questions (M) = 5
Number of hard questions (H) = 3
Now, the probability of getting the first question as easy question is given as:
Now, probability of getting the second question as easy question is given as:
Now, probability that the first two contestants will get easy questions is given by the product of 
. So,
Therefore, the probability that the first two contestants will get easy questions is
