100 minus 95 equals 5
25 equals 5%
100 divided by 5 equals 20
20 times 25 equals 500
500 minus 25 equals 475
Answer:475 students present/ 500 students total in school
The answer is (A) you because the equation is equal to X>2 and answer A is also equal to X>2
Answer:
Step-by-step explanation:
the passengers of hawaiian airlines in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)
We replace this number in the equation :
Hawaiian : 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (1.800.000) =12294012
Northwest airlines: 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (195.000.000) = 131477501
B = tp - (s + 2000) / 3
b=(8000)(12) - (4000 + 2000) / 3
b=(96000) - (6000) / 3
b=96000 - 6000 / 3
Answer
b=£30000
b=£94000
Answer:
H0: μ = 7.8
Ha: μ > 7.8
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above;
Let μ represent the true mean length of long-distance calls after the rate reduction
The null hypothesis is that true mean length of long-distance calls after the rate reduction is the same and equal to 7.8 minutes
H0: μ = 7.8
The alternative hypothesis is that the true mean length of long-distance calls after the rate reduction have increased that is greater than 7.8 minutes
Ha: μ > 7.8
