The probability of matching three out of five numbers is 153/33649

<h3>How to determine the probability?</h3>

The numbers are given as:

1 to 23

There are five matching numbers

The  probability of getting a match is:

p = 5-k/n where k = 0, 1, 2

While the complement probability is

q = (n - 2)/n

Using the above formulas, the probability of getting from 5 is:

P = 5/23 * 4/22 * 3/21 * 18/20 * 17/19

Evaluate the product

P = 153/33649

Hence, the probability of matching three out of five numbers is 153/33649

Anna is saving to buy a new cell phone. Her mother is helping Anna by contributing money each month. What is the ratio between t
Dmitry [639]

Answer:

Option D. 3:1, $120

Step-by-step explanation:        

The complete question in the attached figure    

Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?      

Let    

x -----> the amount of money contributed by Anna      

y ----> the amount of money contributed by her mother    

we know that    

Looking at the table  

The value of x is equal to   x=\$30+\$60+\$90+\$120=\$300  

The value of y is equal to   y=\$10+\$20+\$30+\$40=\$100    

Find the ratio  x/y  

substitute the values  

\frac{x}{y}=\frac{300}{100}=\frac{3}{1}  

Part 2)  What was the total amount saved in April?    

we know that        

To find out the  total amount saved in April, adds Mon's contribution in April plus Anna's contribution in April            

so            

(\$30+\$90)=\$120

How many cones of radius 1 m and height 1 m have total volume equal to the volume of a sphere with a radius 1m?
DiKsa [7]
Vcone=1/3(hpir^2)
Vsphere=(4/3)pir^3

evaluate
vcone=1/3(1pi1^2)=pi/3
vsphere=4/3pi1^3=4pi/3


pi/3 times what=4pi/3
times both sides by 3
pi times what=4pi
divide both sides by pi
1 times what=4
what=4



4 cones

Solve the systems of equations. <br>​
rewona [7]

Answer:

x = -1 and y = -1

Step-by-step explanation:

Solve 3x+3y=−6;−x+y=0

Steps:

I will solve your system by substitution.

−x+y=0;3x+3y=−6

Step: Solve−x+y=0for y:

−x+y+x=0+x(Add x to both sides)

y=x

Step: Substitutexforyin3x+3y=−6:

3x+3y=−6

3x+3x=−6

6x=−6(Simplify both sides of the equation)

6x

6

=

−6

6

(Divide both sides by 6)

x=−1

Step: Substitute−1forxiny=x:

y=x

y=−1

Answer:

x=−1 and y=−1
