Answer:
2 cups of flour
2/3 cup of sugar
1 1/3 cups of chocolate chips
Step-by-step explanation:
3 dozen chocolate chip cookies
3 cups of flour
1 cup of sugar
2 cups of chocolate chips
The recipe is for 3 dozen cookies as stated above.
If you make 2 dozen cookies, then you are making 2/3 of the recipe since 2 is 2/3 of 3.
That means you need 2/3 of all the ingredients.
2/3 × 3 dozen chocolate chip cookies
2/3 × 3 cups of flour
2/3 × 1 cup of sugar
2/3 × 2 cups of chocolate chips
We simplify the amounts to:
2 dozen chocolate chip cookies
2 cups of flour
2/3 cup of sugar
1 1/3 cups of chocolate chips
4 because on a graph it would be proportional 3,5 is going down in a slanted line so next would be 4,4 so answer is c
Answer:
38
Step-by-step explanation:
We have to substitute x with 2 and y with 4
when the sign of a operation is not expressed it means that the operation is a
multiplication
So we have
3*2 + 2*(4)^2
6 + 2*(16)
6 + 32

Answer:
Answer is option a ) 0.53
Step-by-step explanation:
slope = 
Given that a pediatrician wishes to study how the average weight Y (in kilograms) of children changes during the first year of life. He plots these averages versus the age X (in months) and decides to fit a least-squares regression line to the data with X as the explanatory variable and Y as the response variable.
He finds the following quantities:
r = correlation between X and Y= 0.84
x = mean of the values of X = 5.69
y = mean of the values of Y = 6.26
S_x = standard deviation of the values of X = 3.23
s_y = standard deviation of the values of Y = 2.04
Using the formula for slope given above substitute to get
round off to 0.53
Answer is option a ) 0.53
For the first question, the choice at the bottom left corner is the answer.
For the second question, the two equations that represent the system of inequalities are y < 1- 3x and y ≥ 0.5x - 1
