adult ticket = 10
child ticket = 4
Step-by-step explanation:
for example…
- adult ticket = x
- child ticket = y
so that we get a system of equations
9x + 5y = 110…Equation 1
x + y = 14…Equation 2
solve the system of equations, this time I will use the Elimination and Substitution method
9x + 5y = 110
x + y = 14 (multiplied by 5)
↓↓↓↓↓↓↓
9x + 5y = 110
5x + 5y = 70
___________ _
4x = 40
<u>x = 10</u>
to find value of y subtitute x to one of Equation. for example from second Equation…
x + y = 14
10 + y = 14
y = 14 - 10
<u>y = 4</u>
∴ So, the number of each ticket was she bought is <u>10 adult ticket</u> and <u>4 child </u><u>ticket.</u>
B, because 10+40+24 equals 74
Answer:
H0: μc ≤ μs Ha :μc > μs
Step-by-step explanation:
The null and alternate hypotheses can be stated as
H0: μc ≤ μs Ha :μc > μs one tailed test
Where
μc = Mean of college students watching movies in a month
μs = Mean of school students watching movies in a month
For one tailed test of α =0.05 the value of Z= ± 1.645
The critical region will be Z > ± 1.645
It is of importance to note that by rejecting the null hypothesis and accepting the alternate hypothesis we are automatically rejecting all values of mean that are greater than 7.1
Right triangle would be the answer your looking for>
In the metric system, you give a name to the following multiples: 10, 100, 1000, 0.1, 0.01, 0.001, and then you skip three places. So, you have
And thus 0.000001 of something is a micro-something (i.e. one millionth of a certain unit)
