You pick a card at random, put it back, and then pick another card at random.
6, 7, 8, 9.
What is the probability of picking a 9 and then picking a number greater than 7?
Write your answer as a percentage.
Answer:
12.5%
Step-by-step explanation:
There are 4 cards to choose from in the beginning.
Pick 9 out of the 4.
p(9) = 1/4
You put the card back. Now there are again 4 cards.
There are 2 numbers greater than 7: 8 and 9.
p(8 or 9) = 2/4 = 1/2
p(9 then number greater than 7) = 1/4 × 1/2 = 1/8
1/8 = x/100
8x = 100
x = 100/8
x = 12.5%
Answer: 12.5%

Hi guys, I'm having trouble with this problem.
Consider a group of 8 people.
a. How many orders are there for these 8 people to stand in a line?
b. How many ways are there to choose a president, a vice president, and a secretary?
c. How many ways are there to choose a group of 3 people from this group?
Thank you for your time!
B) Answer is 336
Explanation
There are 8 ways for a President to be selected, and have chosen a president there are 7 ways to choose a Vice (from the remaining people). Then, six ways to choose a secretary.
Then, 8*7*6 = 336.
I'm not 100% sure about this as I have used this method for 9 people and two roles, but I'm rather confident the same rules apply.
Complete the table. At the beginning of the summer, there are 15 rabbits living in a field. Each week for the rest of the summer, another rabbit moves in. The equation r=25 + w describes the number of rabbits, r, after a certain number of weeks, w

Based on the above, there are 26 rabbits after 1 week.
There are 33 rabbits after 8 weeks.

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.
For example, after 1 week, we have:
r = 25 + w = 25 + 1 = 26
So there are 26 rabbits after 1 week.
Similarly, after 8 weeks:
r = 25 + w = 25 + 8 = 33
So there are 33 rabbits after 8 weeks.

2. One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is twice the sum of the measures of the first two angles. Find the measure of each angle. [Hint: the sum of the three angles in a triangle equals 180°.] PLEASE SHOW YOUR WORK I WILL MAKE BRAINLIST PLEASE!!!!!!!
Answer:
first angle = 25 degrees
Second angle = 35 degrees
Third side = 120/degrees
Step-by-step explanation:
Let the size of the second angle be x degrees.
One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.
The measure of the third angle is twice the sum of the measures of the first two angles. This means that The third angle = 2( first angle + second angle). So the size of each angle is
First angle (x + 10) degrees
Second angle = x degrees
Third angle = 2(x + 10 + x) = (4x + 20) degrees
Sum of angles in a triangle = 180 degrees. Therefore, x + 10 + x + 4x + 20 = 180 degrees 6x + 30 = 180
6x = 180 - 30 = 150
x = 150/6 = 25 degrees
First angle = x + 10 = 25 +10 = 35
Third angle = 4x + 20 = 4 × 25 + 20
= 100+ 20 = 120 degrees
Hope this helps
Answer:25(1st angle),35(2nd angle),120(3rd angle)
Step-by-step explanation: (/ stands for divide)
180/6=30 (sum of angles/total units=value of one unit, third angle is 4 units as it is twice the sum of first two angles)
30x4=120 (value of unitxnumber of units of 3rd angle=3rd angle)
30x2=60 (value of unitxfirst angle+second angle total units=value of 1st angle+2nd angle)
(60-10)/2=25(1st angle)
25+10=35(2nd angle)
CHECK: 35+25+120=180

F(x)=x^2+10 what is the average rate of change of f over the Interval [-2,-1]?
Answer: -3
Step-by-step explanation:
The average rate of change is \(\frac{f(b)-f(a)}{b-a}\). All we have to do is to plug in our values.
a=-2
b=-1
f(b)=f(-1)=(-1)²+10=11
f(a)=f(-2)=(-2)²+10=14
With our values listed, all he have to do is to plug them in.
\(\frac{11-14}{-1-(-2)} =\frac{-3}{1}=-3\)

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
So far this year, Adam has played 30 games of chess and has only won 6 of them. What is the minimum number of additional games he must play, given that he is sure to lose at least one-third of them, so that for the year he will have won more games than he lost?
A) 24
B) 57
C) 87
D) It is not possible for Adam to do this.
The correct answer is B) 57, but not sure how?
Answer:
Step-by-step explanation:Yikes. Just so we’re all clear—this is not a real SAT question.
So far, Adam’s record is 6 wins/30 games. If he plays x more games, his record will be:
image
You find the minimum x such that the fraction is greater than ½, which would mean he won more than ½ of his games.
Let’s do some math!
image
So if he plays 54 more games, and wins 2/3 of them, he’ll have the same number of wins as losses. Check on that to make sure: He’ll have played 30 + 54 = 84 games, and won 6 + (2/3)54 = 42 of them. Yep, that works.
Now here is where it gets tricky (and why this question is not SAT-caliber). Remember that he’s losing 1/3 of his games. If his 52nd, 53rd, and 54th additional games were win, win, loss, then he would have had, very briefly, a winning record after his 53rd additional game.
His 55th additional game is another chance at a winning record. If he loses that game, then he’ll win the next two, and have a winning record for sure by the 57th additional game. From there, if he continues winning 2/3 of his games, he’ll have a winning record forever.
Find the value of: 24/25 divided by 4/5
Type mixed numbers like this: WholeNumber numerator/denominator
type the whole number then a space...then type the numerator, a slash, and the denominator WITH NO SPACES between each part.
Type fractions like this: numerator/denominator
type the numerator, a slash, and the denominator WITH NO SPACES between each part
Answer:
1 1/5.
Step-by-step explanation:
To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".
For the problem 24/25 ÷ 4/5,
You KEEP the first fraction as is, so 24/25
Then, you SWITCH the sign from division to multiplication.
Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.
The equation is now 24/25 * 5/4, which we can just multiply the numerators and denominators. (or cross cancel first)
24 * 5 = 120
25 * 4 = 100
the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.
