There are four cards numbered 1 through 4. The number 2 card is chosen randomly and not replaced. Find the probability of choosing a second card that is the number 3.
Answer:
1/3
Step-by-step explanation:
since number 2 card was not replaced, we have;
probability of picking a second card, 3;
let S be number of sample space
n(S)= 4
n(3)= 1
Pr(3/2)= 1/3
(because since one was already chosen and n, the sample space would reduce)

Step-by-step explanation: 14+14+5+5=38*2=76 Thats the front and back and then The sides are 6+6+5+5=22*2=44 then the top and bottom are 14 +14+6+6=40*2=80 then add that all up and 44+80+76=200 (Sorry if its a bit confusing to understand)
f(x)=7x-2 g(x)=x2+1 h(x)=3x (x at the corner of 3 ) a- find gh(2) b- find f-1(x)
Answer: 37, [tex]\frac{x+2}{7}[/tex]
Step-by-step explanation:
Given
[tex]f(x)=7x-2\\g(x)=x^2+1\\h(x)=3x[/tex]
now,
[tex]g(h(x))=(3x)^2+1\\g(h(x))=9x^2+1[/tex]
for x=2
[tex]g(h(2))=9\cdot (2)^2+1\\g(h(2))=36+1\\g(h(2))=37[/tex]
Inverse of [tex]f(x)[/tex] is given by
[tex]y=7x-2\\x=\dfrac{y+2}{7}\\\\f^{-1}(x)=\dfrac{x+2}{7}[/tex]
A number is 7 more than 5 times another number and their difference is 78 Find the numbers
Answer:
n = 95.75
m = 17.75
Step-by-step explanation:
n = one number
m = another number
System of Equations:
n = 7+5m
n - m = 78
Substitution Method:
7+5m - m = 78
4m + 7 = 78
4m = 71
m = 17.75
n - 17.75 = 78
n = 95.75
Very easy!!! Find length
Answer:
Option D
Step-by-step explanation:
From the picture attached,
If each block of the graph is a square with the dimension of 1 unit,
Measure of leg 1 = 5 units
Measure of leg 2 = 12 units
By applying Pythagoras theorem in the right triangle given in the picture,
(Hypotenuse)²= (leg 1)² + (leg 2)²
(Hypotenuse)²= (5)² + (12)²
(Hypotenuse)²= 25 + 144
Hypotenuse = √169
Hypotenuse = 13
Therefore, length of the given line will be 13.
Option D is the answer.

Answer:
A. $47,403.20
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
For this, the question is about Simple Interest, so the formula is PRT
p- principal (the amount of money you started with)
r- (rate, also the percentage)
t- time (the amount of time it says, in years or so)
So, they had $45,580
Multiply that by 4%, and 4% is 0.04 so multiply 0.04 x 45,580 = 1,823.20. So, the answer is D
Hope this helps!!

What is the volume of this sphere?
Use a = 3.14 and round your answer to the nearest hundredth.
8 mm
cubic millimeters
Answer:
Volume = 2,143.57 mm³
Step-by-step explanation:
Given:
radius (r) = 8 mm
π = 3.14
Required:
Volume of the sphere
Solution:
Volume of the sphere = ⁴/3πr³
Plug in the values
Volume = ⁴/3 × 3.14 × 8³
= ⁴/3 × 3.14 × 512
= 6,430.72/3
Volume = 2,143.57333
Volume = 2,143.57 mm³ (nearest hundredth)

Write an equation for..
“The child’s tickets cost $4 each and the adult’s ticket cost $8 each. Write an equation that would represent the total cost, T, of purchasing a child’s tickets, c, and an adult’s tickets, a.”
Answer:
cxa=t cause you are mulltipling to find the total cost
Answer:
Step-by-step explanation:
A child´s ticket costs $4 and adults ticket costs $8. If we want one of each we need to add both numbers together, 4 plus 8 equals 12. The total cost of a child ticket and an adult ticket is $12.
The questions asked to write an equation; the equation would be:
C+A=T it could also be written as A+C=T, T=A+C or T=C+A.

Answer:
17.8
Step-by-step explanation:
We can find this because we know that to make a cube, we need to do [tex]c*c*c[/tex] or [tex]c^3[/tex]. With this, we can simplify our equation (by taking the root of both sides) to [tex]c=\sqrt[3]{5639.752}[/tex] or 17.8.
What would be the area of the figure
Answer:
1.3 + 1.3 = 2.6
2.6 x 2.2 = 5.72
5.72 divided by 2 = 2.86
2.86 x 2 = 5.72

p = 5/12
Step-by-step explanation:
-14+6p = -9-6p
Add 6p to each side
-14+6p+6p = -9-6p+6p
-14 +12p = -9
Add 14 to each side
-14+12p = -9 +14
12p =5
Divide by 12
12p/12 = 5/12
p =5/12
