We want to add
The common denominator is 9*15 = 135
Answer: D. 135
This is true. If you count the number of lbs, you get 16 and if you count the number of dollars in the same length, you get $4.
Answer:
Step-by-step explanation:
For the null hypothesis,
H0 : p = 0.63
For the alternative hypothesis,
Ha : p < 0.63
This is a left tailed test
Considering the population proportion, probability of success, p = 0.63
q = probability of failure = 1 - p
q = 1 - 0.63 = 0.37
Considering the sample,
Sample proportion, P = x/n
Where
x = number of success = 478
n = number of samples = 800
P = 478/800 = 0.6
We would determine the test statistic which is the z score
z = (P - p)/√pq/n
z = (0.6 - 0.63)/√(0.63 × 0.37)/800 = - 1.76
From the normal distribution table, the area below the test z score in the left tail 0.039
Thus
p = 0.039
Answer:
infinite solutions
Step-by-step explanation:
18-3n+2=n+20-4n
Combine like terms
20 -3n = 20 -3n
Add 3n to each side
20-3n+3n = 20-3n+3n
20=20
This is a true statement so
infinite solutions
the answer is -3 because i searched it and that’s what came up
