A shipment contains 9 igneous, 7 sedimentary, and 7 metamorphic rocks. If 7 rocks are selected at random, find the probability that exactly 5 are sedimentary.
Answer:
75 percent
Step-by-step explanation:
see the thing is
The probability that exactly 5 are sedimentary is from a shipment which contains 9 igneous, 7 sedimentary, and 7 metamorphic rocks is 21/33649.
What is combination?Combination is the way of arrangement or the collection of items in the particular order. The order of this group of items does not matter in the combination type of arrangement.
A shipment contains 9 igneous, 7 sedimentary, and 7 metamorphic rocks. If 7 rocks are selected at random, find the probability that exactly 5 are sedimentary.
Number of ways to choose 5 sedimentary from 7 sedimentary is,
[tex]^7C_5=\dfrac{7!}{(7-5)!5!}\\^7C_5=\dfrac{7\times6\times5!}{2!5!}\\^7C_5=\dfrac{7\times6}{2\times1}\\^7C_5=21[/tex]
There are total 23 rocks (9+7+7). Number of ways to choose 7 rocks from 23 rocks is,
[tex]^{23}C_5=\dfrac{23!}{(23-5)!5!}\\^{23}C_5=\dfrac{23!}{18!5!}\\^{23}C_5=33649[/tex]
Thus, the probability that exactly 5 are sedimentary is,
[tex]P=\dfrac{21}{33649}[/tex]
Hence, the probability that exactly 5 are sedimentary is from a shipment which contains 9 igneous, 7 sedimentary, and 7 metamorphic rocks is 21/33649.

Lech bought 8 t-shirts al
for the same proe. After
using a coupon that took $4
off the pnce, her told
before tax was $36. What
was the cost of each shirts
Answer:
[tex]t=5[/tex] dollars per t-shirt
Step-by-step explanation:
Read the problem and write your equation while following along with it
We have 8 t-shirts
Lets 8 t-shirts be represented by 8t
So for our equation we will place and [tex]8[/tex]
Our equation: [tex]8t[/tex]Now it says we have a coupon that subtracts 4 dollars from our total
Our equation: [tex]8t-4[/tex]The final part to add to our equation says that our total before tax was 36 dollars
So here is our equation: [tex]8t-4=36[/tex]add [tex]$[/tex][tex]4[/tex] to both sides
[tex]8t=40[/tex]
Divide both sides by [tex]8[/tex]
[tex]t=5[/tex] dollars per t-shirt

You are playing a game where you draw a card from a standard deck, and you will win $13 if you draw a face card,
$3 if you draw an ace and lose $5 if you draw any other card. What is the expected gain from this game?
Round your final answer to the nearest cent.
Answer:
Step-by-step explanation:
win
There are 3 face cards / suit. Every suit contains a Jack, Queen, and king.
There are 4 suits so the number of face cards is 3*4 = 12
There is 1 ace / suit
There are 4 suits so the number of aces is 1 * 4 = 4
The gain from the face cards = 12 * 13 = 156
The gain from the aces = 4 * 3 = 12
Total gain = 168
Losses
Any other card costs you $5
How many cards is that? 52 - 16 = 36
Each one costs 5 dollars
Total loss = 5 * 36 = 180
So each time you play the game, you can expect to lose 180 - 68 = 12 dollars. You should walk away quickly from this one.

Write the equation of the parabola in vertex form.
A. y = x2
B. y = 1/4x^2 + 1
C. y = 1/4x^2
D. y = 1/4( x - 2)^2 + 1
Answer: The answer is NOT Letter B
C. y = 1/4x^2
Step-by-step explanation: I used math.way
A. y = x^2 = Rewrite in vertex form and use this form to find the vertex ( h , k ) . ( 0 , 0 ) =Find the vertex form. y = x 2
B. y = 1/4x^2 + 1 = Rewrite in vertex form and use this form to find the vertex ( h , k ) . ( 0 , 1 ) =Find the vertex form. y = 1 /4 ⋅ ( x + 0 ) 2 + 1
C. y = 1/4x^2 = Rewrite in vertex form and use this form to find the vertex ( h , k ) . ( 0 , 0 ) =Find the vertex form. y = 1 /4 x 2
D. y = 1/4( x - 2)^2 + 1 = Rewrite in vertex form and use this form to find the vertex ( h , k ) . ( 2 , 1 ) = Already in vertex form. y = 1 /4 ( x − 2 ) 2 + 1

Homework 5: Proving Triangles Congruent:
SSS & SAS
Answer:
SSS:
Draw a triangle with sides of 2 cm, 3cm and 4cm and another one of 4cm, 6cm and 8 cm. Both will be SSS congruent.
SAS:
Draw a triangle with sides of 2 cm, 3 cm and another side of your choice. The angle between sides of 2 and 3 cm is 30 degrees. Now draw a triangle with sides of 4 cm, 6cm and another side of your choice (but this one cannot be the double of the 3rd side of the first triangle!) . The angle between the sides of 4 cm and 6 cm should be 60 degrees. Now you have 2 SAS congruent triangles.

The temperature at the North Pole averages -36࿁F. This past winter, the temperature averaged -47࿁F. Write a correct statement that compares the absolute values of the two temperatures
Comparing the temperature average, it can be concluded that the current average temperature is higher than the past average by 11°F
The temperature difference between the present and past winter can be expressed thus :
Current temperature average = - 36°F Past average = - 47°FTemperature difference :
-36 - (-47) = 11°FTherefore, we can conclude that the current average temperature is higher than the past average by 11°F

The graph of h(x) = g(x + 5) has
and
.
The function h(x) has a horizontal asymptote at y=5 and the vertical asymptote is x=-2.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, h(x)=g(x+5.
Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k.
Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k.
Here, the horizontal asymptote is 3, and the vertical asymptote is -2
The graph of h(x) = g(x+5) had a horizontal asymptote at y=5 and the same vertical asymptote as function g(x).
Therefore, the function h(x) has a horizontal asymptote at y=5 and the vertical asymptote is x=-2.
