Answer:
Step-by-step explanation:
Given that the cost of a loaf of bread increases by $0.50 for every $1 increase in the cost of 1 pound of flour.
Let x be the cost of flour and y the cost of bread.
Rate of change of y with respect to x is constant as 0.50
This can be represented as
This can be solved as
y = 0.5x+C where C is the cost of bread even when x=0

Answer:
The probability that she gets all 7 questions correct is 0.0078.
Step-by-step explanation:
We are given that Karri takes a 7 question true-false test and guess on every question.
The above situation can be represented through binomial distribution;
where, n = number of samples (trials) taken = 7 question
r = number of success = all 7 questions correct
p = probability of success which in our question is probability that
question is correct, i.e. p = 50%
Let X = <u><em>Number of question that are correct</em></u>
So, X ~ Binom(n = 7, p = 0.50)
Now, the probability that she gets all 7 questions correct is given by = P(X = 7)
P(X = 7) =
=
= <u>0.0078</u>
1)x+1) has positive slope, it is only A or B
2) For f(x)=4 we have x≥1, so this graph should begin with black dot.
3)So answer is B
Blue dot should be empty.
Orange dot should be black.
