Minor x
major x+1
x + x + 1 = 49
x + x = -1 + 49
2x = 48
x = 48/2
x = 24
Solution
minor x ----------------> 24
major x+1--------------> <u>25</u>
49
Answer:
As probability of that happening is very small; Yes, 33.6 is less than 35.6 grams because it provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.
Step-by-step explanation:
For a normal distribution Z-score
Given that :
the mean (
) = 35.6
standard deviation (
) = 5.2
sample size (n) = 35
standard error: 
The probability that a random sample of 35 bags has a mean weight of 33.6 grams or less is :
P(X<33.6) = P(Z < - 2.28)
= 0.0114
Conclusion:
As probability of the happening is very small; Yes, 33.6 is less than 35.6 grams because it provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.
Check the coordinates of the given points in each of the given possible answer functions (2, –21) and (5, –45), until you find the function satisfied by these two points.
Do these points satisfy the equation y = –8x – 5? Substitute 2 for x and -21 for y and determine whether or not the resulting equation is true:
-21 = -(2) - 5 This is false, and we can state that confidentally even
without checking whether the other given point is a solution.
Moving on to the next equation y = –8x + 5:
Is -21 = -8(2) + 5? Is -21 = -16 + 5? Is -21 = -11? No. Move on to the next equation: y = 8x – 5. Is -21 = 8(2) -5 true? No. Move on to the next equation:
y = 8x+ 5 Is -21 = 8(2) + 5? No.
It appears that the given points (2,-21) and (-5,-45) are not solutions of any of the four given equations.
Answer:
Total number of seats on plane is 150 seats.
Step-by-step explanation:
Number of seats on left side = 2 in each row
Number of seats on right side = 3 in each row
Total number of seats on right side = 90
Number of rows = total number of seats on right side/ number of seats on right in each row
Number of rows = 90 / 3 = 30 rows
So, total number of seats on left side = 30 * 2 = 60 seats
Total number of seats = total seats on right side + total seats on left side
Total number of seat = 90+ 60 = 150 seats
Hence total number of seats on plane is 150 seats.
