Mathematics

Karolina [17]3 years ago

Explanation :

The line DF is parallel to OB, therefore Angle x = Angle y.

( because, they for corresponding angle pair which are equal. )

And the angle made by an arc at center is always double the angle made by the same arc at its boundary, hence

x = 22° × 2

x = 44°

y = 44° ( cuz, x = y )

Vcylinder=hpir^2
Vcone=(1/3)hpir^2

d/2=r

so

1.
d=8
r=8/2=4
h=3r
h=3(4)
h=12
V=12*3.14*4^2
V=602.88 in^2

2. cone that fits has same base area and therefor same radius
d=6
r=6/2=3
rcone=3
find height of can
V=hpir^2
21=h*3.14*3^2
21=h*3.14*9
0.7431=h
so
cone height=0.7431
radius=3
V=(1/3)(0.7431)(3.14)(3^2)
V=7 cubic units

3.
same base
find dimentions
s=s=s
V=s^3
27=s^2
3=s
Vsquarepyramid=(1/3)hs^2
s=legnth of base
h=height
h=side
V=(1/3)(3)(3^2)
V=9
C

1. 602.88 in^2
2. 7 cubic units
3. 9cm^3, C

Michael wants to take French or Spanish, or both. But classes are closed, and he must apply and get accepted to be allowed to en

Brums [2.3K]

Answer:

80%.

Step-by-step explanation:

Given the following probabilities:

P(Micheal Being admitted to French), P(F)=50%
P(Micheal Being admitted to Spanish), P(S)=50%

In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:

P(Micheal Being admitted to BOTH French and Spanish), $P(F \cap S)=20\%$

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).

Probability of either A OR B = $P(F \cup S)$

From Probability Theory:

$P(F \cup S) = P(F)+P(S)-P(F \cap S)\\P(F \cup S) =50+50-20\\P(F \cup S) =80$

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.
