Answer:
B) 10
Step-by-step explanation:
6 + 4 = 10
This can be solved using the system of equations:
5500 = 1000c + 1500s
5 = c + s
As the first equation can have different combinations, it is the second equation that defines just how much acres or corn or strawberries(or mathematically, it defines the values of c or s in the first equation) there are. Therefore, the equation " 5 = c + s" is the constraint.
Answer:
c. One sided t-test
Step-by-step explanation:
One sided t test because we want to compare two means and alternative hypothesis is directional.
Answer:
25% of students attend classes in the evening.
Step-by-step explanation:
The proportion of evening students is the number of evening students divided by the total number of students.
The percentage is the proportion multiplied by 100.
We have that:
In total, there are 15000 students.
3750 are evening students
3750/15000 = 0.25
0.25*100 = 25%
25% of students attend classes in the evening.
Answer:
6 F
Step-by-step explanation:
We want to find the temperature difference
Given that the initial temperature read minus 17 F
And the new temperature is increased by 23 F
The new temperature is
=-17+23= 6 F
Therefore the new temperature is 6F
