The question is:
A recipe for a batch of 3 dozen chocolate chip cookies calls for 3 cups
of flour 1 cup of suger and 2 cups of chocolate chips how much of each
ingredient should be used to make 2 dozen cookies?
find ratio
for 3 dozen batches, you need 3 cups of flour
so dozen of batches=number of cups of flour
then 3 dozen batches is 1 cup of sugar
so every dozen batches is 1/3 cup sugar
then 3 dozen batches is 2 cups choc chips
so every dozen is 2/3 cups choc chips
for 2 batches
that is 2 cup of flour
2/3 cup of sugar
and 4/3 cup chocolate chips
Answer:
x + 3
Step-by-step explanation:
It cuts the y axis at 3 and continues to rise by one
Therefore ax + b gives us 1x + 3 = x + 3

July-September 30
October-December 37
Answer:
Yes, There is significant evidence to conclude that hockey players' birthdates are not uniformly distributed throughout the year.
Step-by-step explanation:
Observed value, O
Mean value, E
The test statistic :
χ² = (O - E)² / E
E = Σx / n = (67+56+30+37)/4 = 47.5
χ² = ((67-47.5)^2 /47.5) + ((56-47.5)^2 /47.5) + ((30-47.5)^2/47.5) + ((37-47.5)^2/47.5) = 18.295
Degree of freedom = (Number of categories - 1) = 4 - 1 = 3
Using the Pvalue from Chisquare calculator :
χ² (18.295 ; df = 3) = 0.00038
Since the obtained Pvalue is so small ;
P < α ; We reject H0 and conclude that there is significant evidence to suggest that hockey players' birthdates are not uniformly distributed throughout the year.
3 of 5 because you can halve each number for example 6 can be halved to make 3 and 10 can be halved to make 5
