I believe it is distributive property
Answer:
They can expect to make $524
Step-by-step explanation:
Lets solve the problem
The form of the linear function is f(x) = m x + b, where m is the slope of the line and b is the y-intercept (value f(x) at x = 0)
∵ The student decided to use the points (0.5, 20) and (3, 150)
to make a better regression equation
- She calculated the slope of the line using the two points
∵
- She substituted the value of m in the form above
∴ f(x) = 52 x + b
- Than she find that the best value of f(x) at x = 0 is 4
∴ f(x) = 52 x + 4
∵ x represents the number of hours
∵ y represents the money
∵ The family decides to extend the yard sale to be 10 hours long
- That means substitute x by 10 in f(x)
∵ x = 10
∴ f(10) = 52(10) + 4
∴ f(10) = 520 + 4
∴ f(10) = 524
∴ They can expect to make $524
2/5 of 120 are covered in sprinkles. Divide 120 by 5 to find 1/5. That is 24 and now times 24 by 2 to get 2/5 which is 48.
So to answer the question: The answer is 48 caramel apples are covered in sprinkles.
Answer:
0.40 or 40%
Step-by-step explanation:
Assuming that no student can hold a position at two companies simultaneously, the probability of a student interning at Hawaiian Airlines or Big Island Candies is simply determined by the sum of each individual probability:
There is a 40% chance that a student interns at Hawaiian Airlines or Big Island Candies.
Answer:
The correlation coefficient of the data set is -0.901
Step-by-step explanation:
x y xx xy yy
1 20 1 20 400
3 14 9 42 196
5 10 25 50 100
9 6 81 54 36
15 4 225 60 16
Formula :
So, Option D is true
Hence the correlation coefficient of the data set is -0.901
