Answer:
1.4 in x.y but in y.x it 4.1
Step-by-step explanation:
Answer:
Option D : $780 is the correct answer.
Step-by-step explanation:
Given expression is:
E = $500 + $7x
We will put all the values of given options to check.
A. Putting 430 in given expression
430 = 500 + 7x
430 - 500 = 7x
-70 = 7x
As the number of items sold cannot be negative, therefore, this option is not correct.
B. 530 = 500 + 7x
530 - 500 = 7x
30 = 7x
x = 4.3 (By dividing both sides by 7)
Which is not a whole number.
C. 680 = 500 + 7x
680 - 500 = 7x
7x = 180
x = 25.71
Which is also not a whole number.
D. 780 = 500 + 7x
780 - 500 = 7x
280 = 7x
7x = 280
x = 40
Which is a whole number.
Hence,
Option D : $780 is the correct answer.

Answer:
0, 4, 8
Step-by-step explanation:
As you have noticed, the difference between the end values of x is 20-4 = 16, and the differences in each interval are 4.
The difference between the end values of y is 12 -(-4) = 16, so the differences in each interval will also be 4.
The missing table values are 0, 4, 8. The completed table is ...

Answer:
1) The tournament can be played in 10 different ways
2) The probability of 5 games being played is 0.40
3) The probability of a team winning two games in a row is 0.80
Step-by-step explanation:
a) From the tree diagram below we can observe that the tournament can be played in 10 different ways.
b)The probability of 5 games being played is
P= (number of possibilities where 5 games are being played) / (Total games)
P = 4 / 10
P= 0.40
c) The probability of a team winning two games in a row is
P = (number of possibilities where a team wins two games in a row) / Total games
P = 8 / 10
P = 0.80
