Pizza Time has collected data about customer pizza topping preferences. They have calculated that P(pepperoni) = 0.7, P(olives) = 0.6, and P(pepperoni or olives) = 0.8. Determine the P(pepperoni and olives).A.0.5

B.0.6

C. 0.7

Answers

Answer:

Option A is correct that is $.5=P(A\capB)$

Step-by-step explanation:

We have given probabilities

P(pepperoni)=0.7

P(olives)=0.6

P(pepperoni or olives)=0.8

We need to find the probability of pepperoni and olives

We have a formula

$P(A\cup B)=P(A)+P(B)-P(A\cap B)$

Here we have say A is the event of peperroni tha is $P(A)=0.7$

B is the event of olives that is $P(B)=0.6$

pepperoni or olives that is is $P(A\cup B)=0.8$

Pepperoni and olives that is $P(A\cap B)$ we have to find

On substituting the values in the formula we will get

$0.8=0.7+0.6-P(A\cap B)$

$0.8=1.3-P(A\cap B)$

$-.5=-P(A\cap B)$

$.5=P(A\cap B)$

On simplifying the equation we will get

$.5=P(A\cap B)$

Therefore, Option A is correct.

The answer would be 0.5. This is because the sum off Olives and Pepperoni is 0.13 and the number of those people who choose Pepperoni or Olives is only 0.8. Thus, the remaining number is now on Pepperoni and olives.

How many micrometers long is one edge of a centimeter cube

Answers

Answer:

10000 micrometers.

Step-by-step explanation:

We have to convert the 1cm length of the edge of the cube to micrometers Remember the following conversion units:

$1* 10^(-6) m= 1 \mu m$ and $1* 10^(-2) m= 1 cm$ denoting m for meters, cm for centimeters and μm or micrometers. In particular, dividing on both sides of the first equation we get the identity $1=(1\mu m)/(1* 10^(-6) m)$

Combine the previous information to get:

$1 cm=1* 10^(-2) m= (1* 10^(-2) m) \cdot (1)= (1* 10^(-2) m)(1\mu m)/(1* 10^(-6) m)=(10^(-2))/(10^(-6))\mu m=10^4 \mu m=10000 \mu m$

Note how we "cancelled" the m symbolically as if it was a variable. This is one of the methods to convert units, and the fractions involved are known as conversion factors.

C.(x + 7)2 – 47
D.(x – 15)2 + 94

Answers

The right answer for the question that is being asked and shown above is that: "D.(x – 15)2 + 94." The function f(x) = x2 + 22x + 58 is translated 4 units to the right and 16 units up. the vertex form of the new function is that D.(x – 15)2 + 94

A line has slope –5(over)3 . Through which two points could this line pass? (1 point)(12, 13), (17, 10)
(16, 15), (13, 10)
(0, 7), (3, 10)
(11, 13), (8, 18)

Answers

The points of the line that has a slope of -5 over 3 is (11,13) (8, 18). This can be computed using the formula of finding the slope of a line which m = y2-y2 over x2-x1. This is computed as follows:

m = 18-13 over 8 - 11
m= 5 over -3 or simplified to m= -5 over 3
