For these questions find the probability of drawing the given cards at random from a standard 52-card deck under each condition: (a) with replacement and (b) without replacement. Write your answers as fractions in simplest form.
2) A club, then a spade
a. With replacement
b. Without replacement
3) An ace, then a queen
a. With replacement
b. Without replacement
Answer:
2
a) 6.37%
b) 6.25%
3
a) 0.60 %
b) 0.59 %
Step-by-step explanation:
2 )
a) With replacement
Probability of extracting a club is 13/52
Probability of extracting a spade is 13/51
13/52 * 13/51
= 6.37 %
b) Without replacement
13/52 * 13/52
= 6.25 %
3) With replacement
Probability of extracting a ace is 4/52
Probability of extracting a queen is 4/51
4/52 * 4/51
= 0.60 %
b) Without replacement
4/52 * 4/52
= 0.59 %

The straight line p. passes through the point
(10,1) and it's porpendicular to the line
equation 2x + y=1. find the equation of P
Answer:
y = 1/2 x - 4
Step-by-step explanation:
Given the equation of the line as 2x+y = 1
Get the slope
y = -2x+1
Slope of the line is m = -2
Slope of the line P will ne M = -1/-2 (since they are perpendicular)
Slope of line P = 1/2
The equation in point slope form is expressed as;
y - y 0 = m(x-x0)
Given that x0 = 10, y = 1
y - 1 = 1/2(x-10)
2(y-1) = x-10
2y - 2 = x-10
2y = x - 10 +'2
2y = x-8
y = 1/2 x - 8/2
y = 1/2 x - 4
This gives the equation of line P

Step-by-step explanation:
By sine rule
[tex] \frac{r}{ \sin \angle R } = \frac{p}{ \sin \angle P} \\ \\ \frac{r}{ \sin 20\degree } = \frac{12}{ \sin 35\degree } \\ \\ r = \frac{12\sin 20\degree}{ \sin 35\degree } [/tex]

Solve the system of equation 2x + y = -4 and 5x – 3y = 1 by the method of elimination
Step-by-step explanation:
first step while implementing the elimination method is to look at the numbers which can be multiplied to which in order to have like terms as solved below
as you can see in equation number 2 that the number three can be multiplied with equation 1 in order to have like terms so you can cancel them out
so , multiply 3 with the whole of equation 1
3( 2x + y = -4 )
= 6x + 3y = -12
( keep in mind the sign of the number)
5x -3 y = 1
now ,
we have
6x + 3y = -12
5x -3y = 1
as you can see that now we have like terms and when we add both these equations the like terms cancel out each other as they have opposite signs ( + - gives you - )
so , once you add the like terms this is what you will get
6x + 5x +3y-3y -12+1
= 11x + 0 - 11
then you can simplify this further for x first
11x = 11
x = 11/11
x = 1
now we have the value of x let's simply further for y
let's take equation 2
5(1) - 3y =1
5 -3y = 1
5-1 = 3y
4 = 3y
4/3 = y
to confirm your values you can put these values in one of the two equations given initially , let's use equation two to check .
5x-3y = 1
( now let's place the values of x and y into the equation and see if our answer is 1 )
5 (1) - 3 (4/3)
= 5 - 4
= 1
it is correct

Actually Welcome to the Concept of the Profit and loss.
Since, in the comparison for the better buy than the 4 boxes for $3.79 is
Option A.) 6 for $5.75
because all other three are costlier than the their original price,
also, 3.79/4 = $0.94
if, $0.94 * 6 = $5.685
so, $5.685 means,the the buy is better that original price.

EASY!! PLEASE HELP!! A silo casts a shadow that is 99 feet long. Next to the silo is an 18-foot-tall barn that casts a shadow that is 13.5 feet long. How tall is the silo?
Answer:
74.24ft tall, you were right!
Step-by-step explanation:
13.5/18 = 0.75
This is the ratio of shadow by actual height that you will use to find the height of the silo so now you multiply:
99*0.75 = 74.25
74.25 is the exact measurement of the taller silo's height.

Paul organised an event for a charity.
Each ticket for the event cost £19.95
Paul sold 395 tickets.
Paul paid costs of £6000
He gave all money left to the charity
Work out the an estimate for the amount of money Paul gave to the charity?
Answer:
The answer is 2000. Hope this helps! If I could have brainliest I'm trying to rank up :)
Step-by-step explanation:
This question asks us to estimate the amount of money Paul gave to Charity.
To work out an estimate we must start by rounding the numbers we are given to 1 significant figure and the
Starting with 19.95 --> this rounds to 20 and 395 rounds to 400.
Then we have to multiply these numbers together:
20 x 400 = 8000
3. Finally subtract 6000 from our estimate
8000-6000=2000
The answer is 2000.
Sophia babysat for 3 5/12 hours on Friday. She babysat for 2 5/6 hours on Saturday. For the following statements, estimate how long Sophia babysat on Friday and Saturday combined. Choose the correct benchmarks and sum.
Answer:
the answer is c for Friday and 6 3/12 hours for them both combined
Step-by-step explanation:
because 3 5/12 is closest to 3 1/2=3 6/12
for fir day and Saturday day combined it would be 6 3/12
because 5/6 is 10/12 and 5/12 + 10/12 is 15/12 which is also 1 3/12
so add 3 +2=5 and then add the fraction 1 3/12 which would be 6 3/12 hours

the triangle was made smaller (i forget what the term is)
it was made smaller by [tex]1\frac{1}{3}[/tex]
to find that you divide 24 by its equivalent side on the other triangle which would be 18
24 / 18 = [tex]1\frac{1}{3}[/tex]
to find what x is equal to you have to find the equivalent side on the other triangle. this would be 16. since the triangle with 16 is bigger the equation is:
16 / [tex]1\frac{1}{3}[/tex] = 12
so x = 12
Hannah and James are married. Every Saturday they take turns to clean their apartment. Hannah cleans it
fast in 3 hours because she does not like to clean. James listens to music, texts, and takes his time while
cleaning. He takes 5 hours. They finally decided to do it together. How long will it take?
Answer:
4 hours
Step-by-step explanation:
I found the average
(3+5)/2
8/2 = 4
This is probably wrong because logically it wouldn't make sense for them to take longer than 3 hours if two people are cleaning but i dont know
Answer:
1 7/8 hours
Step-by-step explanation:
x/3+x/5=1
5x+3x=15
8x=15
x=1 7/8 hours
