Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:
c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values
Multiply both sides by sin(80)
172.274641 = x
x = 172.27 in. (to 2 decimal places)
Answer:
3 treatment conditions were compared in the study.
14 individuals participated in the study.
Step-by-step explanation:
Consider the provided information.
Part (A) How many treatment conditions were compared in the study?
There are two sets of degrees of freedom; one for the numerator and one for the denominator.
F ratio is defined as: 
The formula for between treatment is: 
Substitute 
in above formula.
Therefore, 3 treatment conditions were compared in the study.
Part (B) How many individuals participated in the study?
The error degree of freedom is 
Substitute 
and k=3 in above formula.
Hence, 14 individuals participated in the study.
Answer:
Susan has suggested a correct method to calculate the amount of money
Step-by-step explanation:
Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.
Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.
John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.
Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.
