Step-by-step explanation:
The sequence is as follows :
-59 ,-67 ,-65 ,-53 ,-31 ,...
The first term = -59
The second term = -67
Common difference = second term - first term
To calculate the second term add (-8).
To calculate each additional term, increase the amount added by -8.
Answer:
Step-by-step explanation:
Tickets for the school play sell for $4 each.
Number of tickers sold = x
Total income from the tickets = y
This means when x = 1, y = 4
SO when we sell 1 ticket (x = 1), we make $4 income (y = 4).
If we sell 2 tickets (x = 2), we will make $8 income (y = 8)
If we sell 3 tickets ( x = 3) , we will make $12 income (y = 12)
If we sell 4 tickets ( x = 4), we will make $16 income ( y = 16) etc.
Also note that when we sell 0 tickets (x = 0), we make no income (y = 0).
So if you create a graph, it should look something like this:
Answer:
7 inches
Step-by-step explanation:
area of square=l^2
49=l^2
=l
7=l
therefore the sides of a triangle is 7 inches.
Answer:
P = 0.018
Step-by-step explanation:
In this problem, the null and alterantive hypothesis are:
If the sample has a size of n = 40, the degrees of freedom are 40-1 = 39.
If the value of the test statistic is t = 2.463, we can look up in a t-table to find the p-value. In this test, because the mean can be bigger than 73 or smaller than 73, we have to do a two-tailed test.
For a two-tailed test for t = 2.463 and df = 39, the P-value is P = 0.018.
