In an intro stats class, 57% percent of students eat breakfast in the morning and 80% of students floss their teeth. Forty-six p
WINSTONCH [101]

Answer: B. 11%

Step-by-step explanation:

Let A = Event that students eat breakfast in the morning.

B= Event that students floss their teeth.

We are given P(A)=57%=0.57

P(B)=80%=0.80

P(A∩B) = 46% =0.46

Now, the probability that a student from this class eats break feast but does not floss their teeth :-

P(A-B)=P(A)-P(A\cap B)\\\\ = 0.57-0.46=0.11=11\%

Hence, the probability that a student from this class eats break feast but does not floss their teeth= 11%

Write an exponential function in the form y=ab^x that goes through the point (0,17) and (6,1088)
alexandr402 [8]

Answer:

y = 17(2)^x

Step-by-step explanation:

If the graph of y = ab^x goes through (0, 17), then

                        17 = ab*0, or a = 17

Then the function is y = ab^x with a = 17, or

                                  y = 17*b^x and we must find b.

If the graph of y = 17*b^x also goes through (6, 1088), then the following must be true:   1088 = 17*b^6

which reduces to 64 = b^6

Taking the sixth root of both sides, we get 64^(1/6) = b, and so b = 2

Then the desired exponential function is

y = 17(2)^x
