The variables are:
Matinee ticket ⇒ We can call this item as 'm'
Drink ⇒ We can call this item as 'd'
A bag of popcorn ⇒ We can call this item as 'p'
One matinee ticket costs 6.50
Two matinee ticket cost 2×6.50
Three matinee ticket cost 3×6.50
'm' matinee ticket cost m × 6.50 = 6.50m
One drink costs 5.50
Two drinks cost 2×5.50
Three drinks cost 3×5.50
'd' drinks cost d×3.50 = 3.50d
One bag of popcorn costs 6
Two bags of popcorn cost 2×6
Three bags of popcorn cost 3×6
'p' bags of popcorn cost p×6 = 6p
The expression for total cost is given by
Total = 6.50m + 3.50d + 6p
Answer:
Teachers in his school district have less than 5 yearſ of experience on average is true.
Step-by-step explanation:
Sample mean =
Sample standard deviation = s = 2
We are supposed to to test Ha :u= 5 versus H : u < 5 using a sample of 25 teachers
n = 25
Since n<30 and population standard deviation is unknown
So, we will use t test
Formula :
t=-2.5
Degree of freedom = n-1 = 25-1 = 24
Refer the t table
t critical > t calculated
So, We are failed to reject null hypothesis
So, teachers in his school district have less than 5 yearſ of experience on average is true.
The slope is zero beacuse there is no x
after solving you get
6y = 15
y = 15/6
Upon graphing this a straight line is seen with zero slope
Answer:
9 times 800/9 equals 800. (Answer is 800/9)
Step-by-step explanation:
<u>Key skills needed: Equation, Division, Fractions</u>
1) Let's say the number is the variable "x".
2) So this means 9 times x = 800
9x = 800
3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9
<em>Hope you understood and have a nice day!! :D</em>
It is $27.62 you would save $4.875, you round that up to 88 and you subtract from 32.50 and thats your answer
