Answer:
91
Step-by-step explanation:
Let
x = first number
x+1 = second number
x+2 = third number
x+3 = fourth number
Total = 182
x + x + 1 + x + 2 + x + 3 = 182
4x + 6 = 182
Subtract 6 from both sides
4x + 6 - 6 = 182 - 6
4x = 176
Divide both sides by 4
x = 176 / 4
= 44
x = 44
x = 44
x+1 = 44 + 1 = 45
x+2 = 44 + 2 = 46
x+3 = 44 + 3 = 47
Sum of the two middle numbers = 45 + 46
= 91
55 students are on each bus.take 331 divide by 6 and it's 55 with a remainder of 7. The other 7 students are the remainder.
Picture relating to the required graph is attached below
Answer:
C. (3, 13)
Step-by-step explanation:
According to the inspected scatterplot, we could actually observe a possible data trend which is where the majority of the samples are clustered. In a graphical representation of data, data points which deviates away from the trend of the majority of the points are considered as outliers. In the scenario above, the point (3, 13) seems too far off from the actual trend line, thus showing a greater y value than the pattern actually predicts.
Answer:
Step-by-step explanation:
We are given an equation 5z² + 9z - 2 = 0 and we are to find possible values of z by solving that equation
We will do the task by factorization method:
5z² + 9z - 2 = 0
We can break the midterm (+9z) in two terms such that when they are multiplied the result is -10z² i.e. equal to product of first and third term of the equation above and their sum is equal to 9z
5z² + 10z - z - 2 = 0
5z(z + 2) - 1(z + 2) = 0
taking z+2 common in the above equation
(z+2)(5z-1) = 0
We can write above equation as
(x+2) = 0 (5z-1) = 0
x = -2; 5z = 1
