In a certain sequence, each term, starting with the 3rd term, is found by multiplying the previous two terms. What is the difference between the 6th and 3rd terms in the sequence
Answer:
-3
Step-by-step explanation:
Let the first term be a-d, second term be a and third term be a+d
d is the common difference
If each term, starting with the 3rd term, is found by multiplying the previous two terms then:
a(a-d) = a+d
a²+ad-a-d = 0
a(a+d)-1(a+d) = 0
(a+d)(a-1) = 0
a-1 = 0
a= 1
a+d = 0
1+d = 0
d = 0-1
d = -1
Get the sixth term
nth term of a sequence is expressed as
Tn = a+(n-1)d
T6 = 1+(6-1)(-1)
T6 = 1+5(-1)
T6 = 1-5
T6 = -4
Get the third term T3
T3 = a+2d
T3 = 1+2(-1)
T3 = 1-2
T3 = -1
difference between the 6th and 3rd terms in the sequence is expressed as;
Difference = T6-T3
Difference = -4-(-1)
Difference = -4+1
Difference = -3

Answer:
1) y=2x+5
2) y=-2x+3
3) y=4x+2
Step-by-step explanation:
Okay so the y intercept formula is
y=mx+b
Y is a random y coordinate
m is the slope
x is a random x coordinate
b is y intercept
So first we can make the equation equal to y
Find the slope *dont forget the negatives*
When found the slope, plug it in for b and add x next to it
so now your equation would be something like
y=mx
Now for the B we just start from the origin.
And find the first coordinate to pass the y axis
Now just put it in *ex: if 0,3 is the first coordinate, put 3 as B.
now young got it!

A hardware store sold 630 lawn mowers in one year. If 441 lawn mowers were purchased in the spring, what is the ratio of the number of lawn mowers purchased in the spring to the number purchased during the entire year?
Answer:
[tex]Ratio = 0.7[/tex]
Step-by-step explanation:
Given
[tex]Total = 630[/tex]
[tex]Spring = 441[/tex]
Required
Determine the ratio of lawns in spring to total
[tex]Ratio = Spring:Total[/tex]
[tex]Ratio = 441 : 630[/tex]
Convert to fraction
[tex]Ratio = \frac{441}{630}[/tex]
[tex]Ratio = 0.7[/tex]
Hence, the ratio of lawns sold in spring to the total is 0.7
Answer:
No, the real answer is 7:10
Step-by-step explanation:
441:630 when simlified the answer is 7:10
Fast food chain surveyed a random sample of students to determine what pizza they prefer cheese pizza was referred by 840 students pepperoni pizza was preferred by 28 students based on the results how many of the 340 students can be expected to prefer cheese pizza
Answer: 200 students
Step-by-step explanation:
Here is the complete question:
Fast food chain surveyed a random sample of students to determine what pizza they prefer. Cheese pizza was preffered by 40 students pepperoni pizza was preferred by 28 students. Based on the results how many of the 340 students can be expected to be for cheese
Number of studensts that prefered Cheese pizza = 40
Number of students that prefered pepperoni pizza = 28
Total number of students = 68
Fraction for those that prefer cheese = 40/68 = 10/17
We then multiply the fraction gotten by 340. This will be:
= 10/17 × 340
= 10 × 20
= 200 students

In a survey, 61 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $39 and standard deviation of $3. Find the margin of error for a 99% confidence level.
Answer:
0.989
Step-by-step explanation:
The formula for Margin of Error is:
z × Standard deviation/√n
Where
z = z score for 99% confidence Interval
= 2.576
n = 61 people
Standard deviation = $3
Hence,
Margin of Error
= 2.576 × 3/√61
= 0.989

You might keep your money in a bank, but have you heard of a time
bank? This online service allows users to trade
services with one
another without exchanging money. For example, a hairdresser gives
someone a haircut for one hour of credit in the time bank. The
hairdresser could then use that credit to have a plumber come work for
her for an hour. Time banks are useful for people who can't arrange
direct trades. The plumber might not want a haircut, but he can work
for the hairdresser and earn credit to use with someone else.
How does the detail "The plumber might not want a haircut, but he can work
for the hairdresser and earn credit to use with someone else" best support
the central idea that time banks are a convenient way to get things done?
Explanation:
Of course, the plumber might not want a haircut, but he might have a wife, a fiancee, or a sister who may need the services of a hairdresser so working for the hairdresser would earn him credit that can be used by any of these people. So in a sense, he is getting things done for others.
Therefore, the time-bank service solves a problem by allowing people to receive services without exchanging money.

Joshua babysits for his sister after school. He is paid
$3.00 for each hour of babysitting. He has saved $43.50
and wants to buy a toy that costs $70. What is the least
amount of hours Josh needs to babysit to purchase the
toy?
Plz help
Answer:
9 hrs
Step-by-step explanation:
Joshua has already saved $43.50 so you subtract $43.50 from 70 which leaves you with $26.50. Joshua still needs $26.50.
$26.50 divided by $3 per hr is 8.833 repeating. Obviously you can’t work 8.833 hrs so you round it up to 9. So, Joshua has to work for at least 9 hrs more.
Hope this helps :)

about 49%
We can convert 63% directly to a decimal:
63% = 0.63
Then, doing the calculation by hand or with a calculator, we find
63% of 78 = 0.63 x 78 = 49.14
So the final answer is
63% of 78=49.14
You can round the decimal, if you're looking for a whole number, to about 49%.
