The 7th term of the geometric sequence is 3675/64.

A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a constant called the common ratio.

The 7th term of a geometric sequence can be found using the formula:

a_n = a_1 * (r)^(n-1) where a_1 is the first term of the sequence, r is the common ratio, and n is the position of the term in the sequence.

Given that the common ratio is 3/2 and the first term is 5, we can substitute these values into the formula:

a_7 = 5 * (3/2)^(7-1)

After solving the expression we get:

a_7 = 5 * (3/2)^6 = 5* (243/64) = 15*243/64 = 3675/64

So the 7th term of the geometric sequence is 3675/64.

Therefore, the 7th term of the geometric sequence is 3675/64.

65 seats in 20th row.

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝. In fact, the same symbol is used to represent inversely proportional, the matter of the fact that the other quantity is inverted here.

Given,

No. of seats in 3rd row = 31

No. of seats in 6th row = 37

Seats increase at a constant rate

Let k is the rate of increment.

Difference between no. of seats = k × difference between no. of rows

Difference of seats in 3rd and 6th rows = k difference between the no. of rows

37 - 31 = k ×(6-3)

6 = 3k

k = 2

Thus, we can determine

Difference between the no. of seats is twice the difference between the no. of rows.

Difference between 6th and 20th row = 14 rows

Hence the difference between number of seats = 2 × 14 = 28 seats.

No. of seats in 20th row = No. of seats in 6th row + 28 seats

No. of seats in 20th row = 37 + 28 = 65

Hence, there will be 65 seats in 20th row.

A total of 12,000 dollars is made from the sale of 300 books at a price of $40 each. 25 fewer books are sold for every $5 increase in price.      R(x)=(40+5x)(300−25x) R ( x ) = ( 40 + 5 x ) ( 300 − 25 x )

Assumed in this instance is , At a price of 40 dollars apiece, [tex]$(300)(40 \$)=12,000 \$$[/tex] books generate $300 in revenue. The result is that 25 fewer books are sold if we raise the price of each book by $5. That's [tex]$(300-25 x)$[/tex].

Answer:

1st, 4th and 5th are correct.

Step-by-step explanation:

The values of a and b in the fraction are 21/17 and -8/17

From the question, we have the following parameters that can be used in our computation:

(2x+5)/(x-8)(2x+1)=a/(x-8) + b/(2x+1)

Take the LCM

So, the expression can be expressed as

(2x+5)/(x-8)(2x+1)=a(2x+1) + b(x-8)/(x-8)(2x+1)

Multiply both sides by (x-8)(2x+1)

(2x+5) = a(2x+1) + b(x-8)

Open the brackets

2x + 5 = 2ax + a + bx - 8b

By comparison, we have

2a + b = 2

a - 8b = 5

Make a, the subject in a - 8b = 5

a = 5 + 8b

Substitute a = 5 + 8b in 2a + b = 2

10 + 16b + b = 2

Evaluate the like terms

17b = -8

Divide by 17

b = -8/17

Substitute b = -8/17 in a = 5 + 8b

a = 5 + 8 * -8/17

Evaluate

a = 5 - 64/17

So, we have

a = 21/17

Hence, the values are 21/17 and -8/17

The cost of each box of candy is 31 cents and the cost of each bag of chips is 69 cents.

To find the cost of each box of candy, we first need to find the total cost for all items. We know that Rafael and his sister spent a total of $3.82 + $2.69 = $6.51 on snacks. Since Rafael bought 3 boxes of candy and 1 bag of chips, and his sister bought 2 bags of chips and 1 box of candy, there were a total of 3 + 2 = 5 bags of chips and 3 + 1 = 4 boxes of candy bought.

To find the cost of each box of candy, we divide the total cost for all boxes of candy by the number of boxes of candy: $6.51 / 4 = $1.63 or 163 cents. To find the cost of each bag of chips, we divide the total cost for all bags of chips by the number of bags of chips: $6.51 / 5 = $1.30 or 130 cents.

In the recorded test scores 90 is the mode, as it appears most frequently in the set of ff test scores.

Job applicants submitted their ff test results, which were as follows: 65, 68, 70, 75, 88, 90, 90, 91, and 92. Following that, the Mean (Average) is 81, Median (Middle) is 88, and Mode (Most Common) is 90. The mode can be calculated quite easily.

After sorting the numbers in a set according to their order—lowest to highest or highest to lowest—count how many times each number appears in the group.

The mode is the one that is most prevalent. the quantity that happens the most frequently, or the quantity that appears the most frequently overall. The mode of the numbers 4, 2, 4, 3, 2, and 2 is 2, since it appears three times, more than any other number. The most frequent number in a set of numbers is called the mode.

To find the mode, we first need to put the test scores in order from lowest to highest:

65, 68, 70, 75, 88, 90, 90, 91, 92

Then we can count how many times each number appears:

65: 1 time

68: 1 time

70: 1 time

75: 1 time

88: 1 time

90: 2 times

91: 1 time

92: 1 time

The factored form of quadratic equation 2x² + 7x + 3 is 2(x + 1/2) (x + 3)

A quadratic equation can be expressed in:

- Standard form: y = ax² + bx + c

- factored form: y = a(x - x₁) (x - x₂)

Here, x₁ and x₂ are the roots of the given function.

Suppose we are given a quadratic equation:

y = ax² + bx + c

To find the factored form, use the following properties:

x₁ . x₂ = c/a

x₁ + x₂ = - b/a

In this case, the quadratic function is:

y = 2x² + 7x + 3

We have to find x₁ and x₂ such that:

x₁ . x₂ = 3/2

x₁ + x₂ = - 7/2

An x-y (or bivariate) plot is any graph or plot with two axes.
