Answer:
60
Step-by-step explanation:
4 times 3 = 12 12 times 5 =60
79/100 you can't reduce 79/100 so that would be the simplest form.
Answer:
x < 5
Step-by-step explanation:
–16x > –80
Divide each side by -16, remembering to flip the inequality
-16x/-16< -80/-16
x < 5
Answer:
x`= ∑x P (x)
Step-by-step explanation:
The mean ca be calculated using the formula
x`= ∑x P (x) where x takes the value from 1,2,3,4......i
The sampling distribution is the probability distribution or the relative frequency distribution of the means X` of all possible random samples of the sample size that could be selected from a given population. The mean of this distribution is represented by Ux` and the standard deviation which is called the standard error of the mean S.E (X`)
The mean of the sampling distribution is equal to the population mean that is ux`= u whether the sampling is done with or without replacement.
Answer:
B. a + s = 15
6a + 4s = 76
Step-by-step explanation:
The two equations you want to write are for the two resources, tickets and dollars. We want to know the numbers of adult and senior tickets, so we assign the variables "a" and "s" to those numbers, respectively. We need to keep the meaning of these variables in mind as we write the equations.
a + s = 15 . . . . the sum of the numbers of tickets is 15 (resource = tickets)
The amount spent for tickets of a given type will be the number of tickets of that type, multiplied by the cost of tickets of that type. Then 6a represents the amount spent on adult tickets ($6 each for "a" number of tickets).
6a +4s = 76 . . . the total amount Beth spent on tickets (resource = dollars)
In summary, the two equations are ...
- a + s = 15
- 6a +4s = 76 . . . . . . matches choice B
_____
Beth bought 8 adult tickets and 7 senior tickets.
