Twenty-five bakery customers were surveyed to determine if they like cake or pie. The results are shown in the Venn diagram. Cir
nikitadnepr [17]

Answer:

Probability = 2/7

Step-by-step explanation:

AS the Venn diagram is not given in the question, the question is incomplete. I've attached the Venn diagram of this question below for a better understanding of the question and its solution.

In the Venn diagram we can see that

Costumers who like Cake = 10

Costumers who like Pie = 8

Costumers who like both = 4

So it means that

Total costumers who like Cake = 10 + 4 = 14

Total costumers who like Pie = 8 + 4 = 12

We have to find probabilty that a costumer who likes cakes also likes pie

So

Total costumers who like cake = 14

Costumers out of 14 who also like pie = 4

Probability = (No. of costumers who also like pie) / (Total costumers who like cake)

Probability = 4/14 = 2/7

A plot of 1/no2 versus time is linear. using this information, identify the factor by which the rate will increase in model (c)
WITCHER [35]
This is hard in mathematical language, but there is only this way to present it. Let us denote by A the consentration of the substance and by A' its rate.
We have that b/A= t+c where c is a constant.
Hence A=b/(c+t)
By differentiating, we get that A'=-b/(C+t)^2
Then, we have that -(A)^2=A'/b
Hence at any point, we have that if we make the concentration 17 times, we have that there is a 17 times bigger , the rate will become bigger by 17*17, hence 289 times faster.

Find the coordinates of the midpoint M of ST. Then find the distance between points S and T. Round the distance to the nearest
ololo11 [35]

Answer:

Step-by-step explanation:

M is the midpoint

=>\left \{ {{x=\frac{6+7}{2} } \atop {y=\frac{-3-2}{2} }} \right

⇔\left \{ {x=\frac{13}{2} } \atop {y=\frac{-5}{2}}} \right.

⇒M(\frac{13}{2};\frac{-5}{2})

ST=\sqrt{(7-6) ^{2} +(-2+3)^{2}=\sqrt{2}=1.414
