The probability that a student has either a vise card or a master card is: 0.72
Step-by-step explanation:
Given that
Probability that a student has a vise card = P(V) = 0.65
Probability that a student has a master card = P(M) = 0.20
Probability that a student has both = P(V∩M) = 0.13
We have to find the probability of V OR M
The probability is given by:

Putting the values,

Hence,
The probability that a student has either a vise card or a master card is: 0.72

Answer:
The first one.
Step-by-step explanation:
solving for x:
5/2 = 7.5/x
cross multiply
2 ×7.5 =5x
x= 2×7.5/5
x= 3
solving for y:
values of the small triangle over the bigger triangle-
5/6 =7/y
cross multiply and solve for y
y= 8.4
therefore (x= 3; y= 8.4)

ANSWER
The height of the larger cone is 3cm
EXPLANATION
Since the two cones are similar we can use the scale factor to determine the height of the larger cone.
It was given that, the volume of the larger cone is 27 cm³ and the volume of the smaller cone is 8 cm³.
The scale factor for the volume is

The scale factor for the length is
![k = \sqrt[3]{ \frac{27}{8} }](https://tex.z-dn.net/?f=k%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B27%7D%7B8%7D%20%7D%20)

To find the height of the larger cone, we multiply by
Answer:
y = 3x + 2 is the equation
Step-by-step explanation:
y intercept is where x is 0 that means y intercept is 2.
slope is change in y over change in x which is 3
