The arithmetic sequence a; is defined by the formula:

ai = ai-1 + 11
Find the sum of the first 650 terms in the sequence.
Answers
Answer:
The sum of the first 650 terms of the given arithmetic sequence is 2,322,775
Step-by-step explanation:
The first term here is 4
while the nth term would be ai = a(i-1) + 11
Kindly note that i and 1 are subscript of a
Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula
Sn = n/2[2a + (n-1)d)
Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.
Plugging these values, we have
Sn = (650/2) (2(4) + (650-1)11)
Sn = 325(8 + 7,139)
Sn = 325(7,147)
Sn = 2,322,775

Answers
Answer:
The data table is attached below.
Step-by-step explanation:
The average of a set of data is the value that is a representative of the entire data set.
The formula to compute averages is:
[tex]\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}[/tex]
Compute the average for drop 1 as follows:
[tex]\bar x_{1}=\frac{1}{3}\times[10+11+9]=10[/tex]
Compute the average for drop 2 as follows:
[tex]\bar x_{2}=\frac{1}{3}\times[29+31+30]=30[/tex]
Compute the average for drop 3 as follows:
[tex]\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33[/tex]
Compute the average for drop 4 as follows:
[tex]\bar x_{4}=\frac{1}{3}\times[102+100+98]=100[/tex]
Compute the average for drop 5 as follows:
[tex]\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67[/tex]
The data table is attached below.
The average of the numbers in the data table will be 10, 30, 59.33, 100, and 124.67.
How to explain the data table?The average for drop 1 will be:
= 1/3 × (10 + 11 + 9)
= 10
The average for drop 2 will be:
= 1/3 × (29 + 31 + 30)
= 30
The average for drop 3 will be:
= 1/3 × (59 + 58 + 61)
= 59.33
The average for drop 4 will be:
= 1/3 × (102 + 100 + 98)
= 100
The average for drop 5 will be:
= 1/3 × (122 + 125 + 127)
= 124.67

The FDA regulates that fresh Albacore tuna fish contains at most 0.82 ppm of mercury. A scientist at the FDA believes the mean amount of mercury in tuna fish for a new company exceeds the ppm of mercury. The hypotheses are: H0:µ = 0.82 H1:µ > 0.82 What is a type II error in the context of this problem? A. The fish is accepted by the FDA when in fact it had more than 0.82 ppm of mercury. B. The fish is accepted by the FDA when in fact it had less than 0.82 ppm of mercury. C. The fish is rejected by the FDA when in fact it had less than 0.82 ppm of mercury. D. The fish is rejected by the FDA when in fact it had more than 0.82 ppm of mercury.
Answers
Answer:
Option A
Step-by-step explanation:
A type II error occurs when the researcher fails to reject the bull hypothesis when it is false.
In this study, the
null hypothesis is H0:µ = 0.82 while the alternative hypothesis is H1:µ > 0.82
Thus, the type II error will be that the fish is accepted by the FDA when in fact it had more than 0.82 ppm of mercury.

Answers
Answer:
The cost of each drink was $9.25 and the cost of each popcorn was $5.5
Step-by-step explanation:
Let the cost of each drink be d
Let the cost of each popcorn be p
Steven spends $138.50 for 12 drinks and 5 bags of popcorn. This implies that:
12d + 5p = 138.50 _________ (1)
Jennifer buys two drinks and seven bags of popcorn for a total of $57. This implies that:
2d + 7p = 57 ______________(2)
We have two simultaneous equations/
12d + 5p = 138.50 _________ (1)
2d + 7p = 57 ______________(2)
Multiply (2) by 6 and subtract (1) from it:
12d + 42p = 342
- 12d + 5p = 138.50
———————————
37p = 203.5
p = $5.5
Puutting the value of p back in (2):
2d + 7(5.5) = 57
2d + 38.5 = 57
2d = 57 - 38.5 = 18.5
d = 18.5 / 2 = $9.25
The cost of each drink was $9.25 and the cost of each popcorn was $5.5

URGENT!! A 16 inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 5 times as long as the first piece. If x represents the length of the first piece, find the lengths of all three pieces. what is the length of the first piece, the second piece, and third piece?
Answers
Answer:
Step-by-step explanation:
let length of first piece = x in
length of second piece = 2x
length of third piece = 5x
x+2x+5x= 16
8x =16
x =16/8
x=2
length of :
first piece =2 inches
second piece = 4 inches
third piece = 10 inches..
please mark me as the brainliest..
Answer:
2, 4, 10 in
Step-by-step explanation:
The first piece is x thus the second piece is 2x ( twice as long as first ) and
the third piece is 5x ( five times as long as the first )
Add the 3 together and equate to 16
x + 2x + 5x = 16, that is
8x = 16 ( divide both sides by 2 )
x = 2
Thus
first piece = x = 2 in
second piece = 2x = 2 × 2 = 4 in
third piece = 5x = 5 × 2 = 10 in
