Answer:
267
Step-by-step explanation:
let's say that
f(0)=-25
so in the sequence we are adding 4
so f(1)=-25+4=-21
and f(2)=f(1)+4=-25+4+4=-25 + 4(2)
so if you continue you will notice that
f(n)=-25+4(n)
so our question is
What is the 74th term of this arithmetic sequence?
so if f(0) is our first term, the 74th will be f(73)
so we can apply our formula
f(73)=-25+4(73)
=-25+292
=267
in the standard (x,y) coordinate plane, what is the slope of the line 4x+7y=9?
Answer: -4/7
Step-by-step explanation:
To find the slope, let's change the equation to slope-intercept form.
[tex]4x+7y=9[/tex] [subtract both sides by 4x]
[tex]7y=-4x+9[/tex] [divide both sides by 7]
[tex]y=-\frac{4}{7}x+\frac{9}{7}[/tex]
Now, we know the slope is -4/7.
help? 5/12 + 5/8
(spam cause i need 20 characters)
Answer:
1 1/24
Step-by-step explanation:
5/12 + 5/8
We need a common denominator of 24
Convert the first number to have a denominator of 24
5/12 *2/2 = 10/24
Convert the second number to have a denominator of 24
5/8*3/3 = 15/24
Add the two converted numbers together
10/24 + 15/24
25/24
Change from an improper fraction to a mixed number
24/24 + 1/24
1 1/24
Answer:
25/24
Step-by-step explanation:
5/12 * 1 = 5/12
1 = 2/2
5/12 * 1 = (5/12) * (2/2) = (5*2)/(12*2) = 10/24
3/3 = 1
5/8 * 1 = (5/8) * (3/3) = (5*3)/(8*3) = 15/24
then:
(5/12) + (5/8) = (10/24) + (15/24) = (10+15) / 24 = 25/24

which function is the inverse of f(x) equals negative 5X -4
Answer:
f inverse x = -x+4/5
Step-by-step explanation:
Answer:
f^-1(x) = -1/5 x - 4/5
Step-by-step explanation:
f(x) = -5x - 4
Replace f(x) with y.
y = -5x - 4
Switch x and y.
x = -5y - 4
Solve for y.
5y = -x - 4
y = -1/5 x - 4/5
Replace y with f^-1(x).
f^-1(x) = -1/5 x - 4/5

Please help, "What if you magnified the image of a cluster fly (9 millimeters) by 9*10 exponent 3? What would the length appear to be?" Please hElP
Answer:
9000
Step-by-step explanation:
This is written in scientific notation. When you have a positive exponent (x³), You move the decimal point to the right as many times as the exponent says. Since the exponent is +3, move the decimal to the right 3 spaces:
[tex]9.0(0)\\\\90.0(1)\\\\900.0(2)\\\\9000.0(3)[/tex]
So:
[tex]9*10^3=9000[/tex]
:Done
*Magnifying means that the image will be bigger. So, the new number has to be greater than 9. Since 9000>9, this is true.

Your math test scores are 76, 85, 92, and 63. What is the lowest score you can earn on the next test and still achieve an average of at least 75?
Hey there! I'm happy to help!
We have 5 test scores that give us an average of at least 75.
76, 85, 92, 63, x
We add these all up and divide by 5 to get 75.
Let's go backwards to find x.
We multiply by 5.
75(5)=375
We subtract all of the numbers except for x.
375-76-85-92-63=59
So, you need to earn at least 59 on the next test to achieve an average of at least 75.

4. Thoughtful Politicians [This problem setting is due to Prof. James Norris of Cambridge University.] In a group of 100 politicians, 40 are in Party I and 60 are in Party II. Members of Party I are incapable of changing their minds about anything. Members of Party II change their minds completely randomly every day, independently of all others and also independently of all evidence. Tomorrow, the politicians are going to vote on Proposition 88. Here is a summary of their opinions today. Of the 40 members in Party I, 25 are in favor of Prop 88 and 15 are against. Of the 60 members in Party II, 10 are in favor and 50 are against. Assume that each member in Party II changes their mind based on the toss of a coin: if it lands heads they switch to the opposite opinion and if it lands tails they don't change their mind. a) What is the distribution of the number of members in Party II who will favor Prop 88 tomorrow
Answer:
Step-by-step explanation:
The focus is on Party 2, because as already said, Party 1 members NEVER change their minds on anything!
There are 60 politicians in Party 2. They change their minds completely-randomly every day.
Tomorrow, the politicians will vote on a proposition: Proposition 88, but today, 10 are in favor of it while 50 are against it.
Each member changes their mind based on the toss of a coin (a fair/unbiased coin; since it was not stated that the coin is biased). A fair coin has a 0.5 probability of landing HEADS and same 0.5 probability of landing TAILS.
What is the distribution of the number of members in Party II who will favor Prop 88 tomorrow?
The number of figures in the distribution will depend on the number of times the coin is tossed, between today and tomorrow.
KEY: Assuming the coin is tossed 12 times between today and tomorrow AND assuming that half of the time - 6 times - it landed HEADS and half of the time, TAILS (Head and Tail simultaneously).
Beginning with HEADS, the distribution of the number of members who will favor the proposition tomorrow, is:
50, 10, 50, 10, 50, 10, 50, 10, 50, 10, 50, 10
Landon babysits and works part time at the water park over the summer. One week, he babysat for 3 hours and worked at the water park for 10 hours and made $109. The next week he babysat for 8 hours and worked at the water park for 12 hours and made $177. How much does Landon make per hour at each job?
Answer:
Babysitting =$8.7
Water park =$8.7
Step-by-step explanation:
In 1 week
Babysitting =3 hrs
Water park = 10 hrs
Total =$ 109
In week 2
Babysitting = 8 hrs
Water park = 12 hrs
Total= $ 177
Both weeks
Babysitting =11 hrs
Water park =22 hrs
Total=$286
33 hrs = $ 286
11 hrs =?
11×286÷33=$95.3
33 hrs = $286
22 hrs = ?
22×286÷33=190.7
Babysitting she got $95.3 in both weeks
Water park she got $190.7(rounded offf)in both weeks
11 hrs = $95.3
1 hr = ?
1×95.3÷11=8.7 (rounded off )
22 hrs = $ 190.7
1 hr = ?
1×190.7÷22= 8.7( rounded off)

The pizza itself is $18. If you wanted 5 toppings you would do .50 multiplied by 5. That would give you a total of $2.50 for the 5 toppings. 18 plus 2.50 is 20.50.
Answer:
A large pizza with 5 toppings will be $20.50
A small pizza with 5 toppings will be $14.50
5 toppings would cost $2.50
Step-by-step explanation:
.50x5=2.50
18.00x2.50=20.50

The manager of a movie theater randomly surveyed 50 people who entered the movie theater on Friday. The manager asked about the
type of movie each person preferred. The results of the survey are shown in the table.
Survey Results
Type of Movie Number of People
Horror
12
Comedy
15
Action
17
Drama
6
Based on the results in the table, which statement about a person who will go to this theater next Friday is true?
O A. The person is three times as likely to prefer comedy as horror.
OB. The person is twice as likely to prefer drama as horror.
o C. The person is less likely to prefer horror or drama than action.
D. The person is more likely to prefer horror or comedy than action or drama.
Answer:
D.
Step-by-step explanation:
Horror (12) + Comedy (15) = 27
Action(17) + Drama(6) = 23
27 > 23
The statement that is true is a person who will go to this theatre next Friday is more likely to prefer horror or comedy than action or drama.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
As is given that the total number of people surveyed is 50, while the table suggests the preferences of the people about the movie.
Therefore, if take the probability of a person watching a horror or comedy movie it will be,
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
[tex]\rm Probability=\dfrac{\text{Number of people preferring Horror or comedy}}{\text{Total Number of people surveyed}}\\\\Probability = \dfrac{12+15}{50} = 0.54[/tex]
The probability of a person watching an action or drama movie it will be,
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
[tex]\rm Probability=\dfrac{\text{Number of people preferring Action or drama}}{\text{Total Number of people surveyed}}\\\\Probability = \dfrac{17+6}{50} = 0.46[/tex]
Since the probability of a person watching a horror or comedy movie is more, therefore, a person who will go to this theatre next Friday is more likely to prefer horror or comedy than action or drama.
Thus, the statement that is true is a person who will go to this theatre next Friday is more likely to prefer horror or comedy than action or drama.

A batch of 400 containers for frozen orange juice contains 5 that are defective. Two are selected, at random, without replacement from the batch. 26. What is the probability that the second one selected is defective given that the first one was defective? HINT: Note that you are only calculating a probability for the second draw conditional on what happened in the first draw. 27. What is the probability that both are acceptable? 28. If three are selected without replacement, what is the probability that all three are defective?
Answer:
0.0100250
0.0001566
0.0000009445555
Step-by-step explanation:
Given the following :
Total number of containers = 400
Number of defective oranges = 5
2 are randomly selected without replacement :
A.) What is the probability that the second one selected is defective given that the first one was defective?
Since selection is without replacement and given that the first pick is defective ; number of defective oranges left = 4 ; total oranges left in container = (400 - 1) = 399
Hence,
Probability = (required outcome / Total possible outcomes)
P(2nd defective given 1st is defective) = 4 / 399
27. What is the probability that both are acceptable?
This means probability that both picks aren't defective.
Ist pick = 1 - P(defective) = (1 - (395/400) = 0.0125
2nd pick = 1 - P(defective) 1 - (394/399) = 0.0125313
.Hence, 0.0125 × 0.0125313 = 0.0001566
28. If three are selected without replacement, what is the probability that all three are defective?
1st pick = 5 / 400 = 0.0125
2nd pick = 4 / 399 = 0.0100250
3rd pick = 3 / 398 = 0.0075376
Hence, (0.0125 × 0.0100250 × 0.0075376) = 0.0000009445555
