The sum of the fifth and sixth term of an AP is 30.If the third term is 5.Find the first term.
Answer:
The first term is -3.
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between two consecutive terms is always the same, and it is called common difference d.
The nth term is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term.
If we have the mth term instead of the first, we have:
[tex]a_n = a_m + (n-m)d[/tex]
We have the third term, and need the fifth and the sixth:
So we write both the fifth and the sixth in function of the third, then:
[tex]a_5 = a_3 + 2d = 5 + 2d[/tex]
[tex]a_6 = a_3 + 3d = 5 + 3d[/tex]
The sum of the fifth and sixth term of an AP is 30
We use this to find [tex]d[/tex]. So
[tex]a_5 + a_6 = 30[/tex]
[tex]5 + 2d + 5 + 3d = 30[/tex]
[tex]5d + 10 = 30[/tex]
[tex]5d = 20[/tex]
[tex]d = \frac{20}{5} = 4[/tex]
First term:
The third term is:
[tex]a_3 = a_1 + 2d[/tex]
Since [tex]a_3 = 5, d = 4[/tex]
[tex]a_1 = a_3 - 2d = 5 - 8 = -3[/tex]
The first term is -3.

Mo has a credit card that gives a 3% discount on every purchase. The annual percentage rate on the card is 12%. He is purchasing an electronic reader for $140. Check all that apply.
If Mo uses the credit card and pays the full balance during the billing cycle, the cost of the purchase will be $140.
If Mo pays cash, the cost of the purchase will be $140.
If Mo uses the credit card and pays off the balance at $30 a month for 7 months with no late fees, the cost of the purchase will be $143.34.
If Mo pays cash, the cost of the purchase will be $135.80.
If Mo uses the credit card and pays off the balance at $20 a month for 7 months with no late fees, the cost of the purchase will be $139.89.
If Mo uses the credit card and pays the full balance during the billing cycle, the cost of the purchase will be $135.80.
I want an actual explanation, not just an answer please
Answer:
B: If Mo pays cash, the cost of the purchase will be $140.
E: If Mo uses the credit card and pays off the balance at $20 a month for 7 months with no late fees, the cost of the purchase will be $139.89.
F: If Mo uses the credit card and pays the full balance during the billing cycle, the cost of the purchase will be $135.80.
Step-by-step explanation:
If Mo pays in cash, the cost of the purchase will be $140. Then the correct options are B, E, and F.
What is APR?APR on a credit card is the way of saying that the interest you are charged over a year is equal to roughly of your balance.
Mo has a credit card that gives a 3% discount on every purchase.
The annual percentage rate on the card is 12%.
He is purchasing an electronic reader for $140.
The cost of the purchase will be $139.89 if Mo uses the credit card and pays off the balance at $20 per month for 7 months with no late penalties.

Step-by-step explanation:
At the U.S. Open Ternis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 97 miles per hour (mph) and the standard deviation of the serve speeds was 13 mph. Assume that the statistician also gave us the information that the distribution of the serve speeds was mound-shaped and symmetric. What proportion of the player's serves was between 110 mph and 136 mph

Answer:
[tex]\=x'=\$10.55[/tex]
[tex]\sigma'=10.55[/tex]
Step-by-step explanation:
From the question we are told that:
Raise[tex]r=2\%[/tex] at Time interval 6 months
Time [tex]t=2 years[/tex]
Mean hourly pay [tex]\=x=$9.75[/tex]
Standard deviation[tex]\sigma=\$0.87[/tex]
Generally the equation for mean is mathematically given by
[tex]\=x=P*(1+r)^n[/tex]
Where
[tex]P=Principle\ mean[/tex]
[tex]n=number\ of\ intervals[/tex]
[tex]n=2years/6months[/tex]
[tex]n=4[/tex]
Therefore
[tex]\=x'=9.75*(1+0.02)^4[/tex]
[tex]\=x'=\$10.55[/tex]
Generally the equation for Standard deviation is mathematically given by
[tex]\sigma'=P'*(1+r)^n[/tex]
Where
[tex]P'=Principle\ Standard\ deviation[/tex]
Therefore
[tex]\sigma'=0.87*(1+0.02)^4[/tex]
[tex]\sigma'=10.55[/tex]

Option C is the only table that represents a data set that could be fit to a normal distribution curve.
In a normal distribution, the data is symmetrically distributed around the mean, and the percentages decrease as you move away from the mean.
Option C exhibits this characteristic, where the percentages are highest at the mean values (5, 6, 9, 10) and decrease as you move away from the mean.
Where as the tables in options A, B, and D do not exhibit the characteristics of a normal distribution as the percentages do not decrease symmetrically away from the mean values.

A can do a piece of work in 10 days, B in 12 days and C in 15 days. How long will it take them it together to complete it ?
Explanation -:We observe here that A can do the work in 10 days; B can do the same work in 12 days whereas C can do the same work in 15 days. We are asked to calculate how much time will it take if three of them will work together.
We will solve this problem with traditional method.

D The new line would be less steep than the original line.
Step-by-step explanation:
Assuming the slope is change from 3 to 1/3, the new line would be less steep.
__
The steepness of a line increases as the magnitude of the slope increases. The slope 1/3 is less than 3, so a line with that slope is less steep than a line with a slope of 3.

if -2x+ y =6 and -7x-4y=-8 are true equations what would the value of -9x-3y
Answer:
[tex]-\frac{106}{5} or -21.2[/tex]
Step-by-step explanation:
First we would have to get x and y-values by solving systems of equations:
isolate one of the variable from any of the first 2 equations given:
-2x+ y =6 would be y = 2x + 6 when y is isolated.
now plug this equation in for the y given in the second equation:
-7x -4(2x + 6) = -8
Now solve to get the x-value,
-7x - 8x - 24 = -8
-15x - 24 = -8
-15x = 16
x = [tex]-\frac{16}{15}[/tex] or -1.06
To solve for y-value, substitute the gotten x-value in any of the 2 equations and solve:
y = 2([tex]-\frac{16}{15}[/tex]) + 6
y = [tex]\frac{58}{15}[/tex] or 3.86
Now that we have the x and y-values, substitute them in for the 3 equation given:
-9([tex]-\frac{16}{15}[/tex]) -3( [tex]\frac{58}{15}[/tex])
=> [tex]-\frac{106}{5}[/tex] or -21.2 = Final Answer

9514 1404 393
Answer:
1173 in
Step-by-step explanation:
The measure of angle O is ...
O = 180° -N -P = 180° -32° -97° = 51°
The law of sines tells you ...
o/sin(O) = n/sin(N)
o = n·sin(O)/sin(N) = (800 in)·sin(51°)/sin(32°)
o ≈ 1173 in
