Answer:
7th graders- 100 students
8th graders- 110 students
Step-by-step explanation:
Let the number of 8th graders be represented by x and 7th graders be represented by y
<u>Equation based on number</u>
There difference between 8th and 7th graders is 10 hence equation becomes
x-y=10
<u>Equation based on contribution</u>
While x contribute each $8 and y contribute each $5, the total contribution is $1380 hence the equation becomes
8x+5y=1380
<u>Combining equations</u>
Having the two simultaneous equations which are
x-y=10
8x+5y=1380
Solving the equations.
5x-5y=50
8x+5y=1380
------------------
13x=1430
x=1430/13=110
Therefore, 8th graders are 110. Since the 8th graders were 10 more than 7th graders, the 7th graders will be 110-10=100 students
Answer:
Step-by-step explanation:
The happiest used in a test in statistics are the null and the alternative hypothesis. The null hypothesis is usually the default statement while the alternative hypothesis is thevopposite of the null hypothesis.
In this case study, the null hypothesis is u1 = u2: the average mean time it takes to accelerate to 30 miles per hour for car 1 is the same as that for car 2.
The alternative hypothesis is u1 > u2: the mean time it takes to accelerate to 30 miles per hour is greater than that for car 2 thus car 1 is slower to accelerate as it takes more time.
It depends on how many players are on each team if I'm thinking right. How many are there?
