Question Continuation:
a. both of them winning their respective States.
b. both of them lose in their respective States.
c. at least one of them wins in his state.
Answer:
Question 1
Total number of marbles = 5 + 7 + 8 = 20
(a)
P(red, red) = 5/20*4/19 = 1/19(b)
P(white and blue) = P(white, blue or blue, white) = 7/20*8/19 + 8/20*7/19 = 14/95 + 14/95 = 28/95(c)
P(both same colour) = P(red,red or blue,blue or white,white) = 1/19 + 8/20*7/19 + 7/20*6/19 = (20 + 56 + 42)/380 = 118/380 = 59/190Question 2
P(A) = 2/9P(B) = 4/11(a)
P(A and B) = 2/9 * 4/11 = 8/99(b)
P(not A and not B) = (1 - P(A))(1 - P(B)) = 7/9*7/11 = 49/99(c)
P(A or B) = 1 - P(not A and not B) = 1 - 49/99 = 50/99An object is launched from the roof of a building 192
feet above the ground. The object's height (in feet)
after t seconds is given by the function
h(t) = -16° +64t + 192
A) What is the height of the object after two-and-a-half
seconds?
252 ft
256 ft
312 ft
620 ft
Answer:
252 ft
Step-by-step explanation:
h(t) = -16t^2 +64t + 192
We want to find h when t= 2.5
h(2.5) = -16 (2.5)^2 +64(2.5) +192
=-16(6.25) +160+192
=-100+160+192
=252

A basketball coach had her team practice free throws. The team attempted 308 free throws altogether. They made 6 times as many free throws as they missed. How many free throws did the team miss?
Let the number missed = x
They made 6 times that amount which would be 6x
The total of missed and made is 308:
X + 6x = 308
Combine like terms
7x = 308
Divide both sides by 7
X = 44
They missed 44
Cone 1 is congruent to cone 2 with dimensions given in units as shown below
What is the surface area of cone 2 ?
Please help !! ASAP giving 30 points too correct answer choice
Surface area of cone2 is equals to 96π.
What is surface area?
"Surface area is defined as the sum of the area of all the faces of given three dimensional shape."
Formula used
Surface area of the cone = πr² + πr l
According to the question,
Given,
'r' represents the radius of the cone
'h' represents the height of the cone
'l' represents the slant height of the cone
Cone1 and Cone2 are congruent cones.
⇒Radius of cone1 = Radius of cone2
Slant height of cone1 = Slant height of cone2
As per the given dimensions we get,
Radius of both the cones 'r' = 6units
Slant height of both the cones 'l' = 10units
Substitute the values in the formula we get,
Surface area of the cone2 = π (6)² + π (6) (10)
= 36π +60π
= 96π square units
Hence, surface area of cone2 is equals to 96π.

Patterns are made using straight lines and arcs.
Pattern A (one row)
Pattern B (two rows)
More rows are added to Pattern B so that
number of straight lines : number of arcs = 7:6
How many rows are added?
5 rows are to be added in the pattern if the ratio will be 7:6 between number of straight lines.
What is a pattern?
A pattern is a sequence. It can be an AP, GP also.
How to determine the number of rows to be added?
present ratio between number of straight lines and number of arcs
=8:9
When we add 1 row it will increase 4 straight lines and 3 arcs. So when 5 rows are added it will increase 20 straight lines and 15 arcs.
Then total number of straight lines will be 28 and the total number of arcs will be 24 and the ratio will be 28:24 which after dividing by 4 becomes 7:6.
Hence 5 rows are to be added in the pattern B to get the ratio 7:6.
