Find the missing terms of the arithmetic sequence ...,27,?,?,?,53,... Show each step of the process clearly

Alja [10]

Answer:

Step-by-step explanation:

Looking at the arithmetic sequence, the 4th term is 27 the 8th term is 53. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

Therefore, the 4th term, T4 will be

27 = a + (4 - 1) d

27 = a + 3d - - - - - - - - 1

The 8th term, t8 would be

53 = a +(8 - 1) d

53 = a + 7d - - - - - - - - -2

Subtracting equation 1 from equation 2, it becomes

- 26 = - 4d

d = - 26/- 4 = 6.5

Substituting d = 6.5 into equation 1, it becomes

53 = a + 7 × 6.5

53 = a + 45.5

a = 53 - 45.5 = 7.5

The missing terms are

7.5, 14, 20.5, 27, 33.5, 40, 46.5, 53

A survey of the men in a certain town showed that 35% of the men have blond hair and 14% of them have blond hair and blue eyes.

natita [175]

If you are given he has blond hair, so the total probability will be 35%. And among them, he needs to have blue eyes, its probability is 14% among the 35%. So the final probability is 14%/35%=40%.

Answer:

c) 60,480

Step-by-step explanation:

9×8×7×6×5×4×3×2×1

3×2×1

Cancel same numbers in the numerator and denominator.

So you're going to have= 9×8×7×6×5×4 divided by 1

Which gives you, 60,480.

A gift basket that contains jars of jam and packages of bread mix costs $45. There are 8 items in the basket. Jars of jam cost $

nordsb [41]

5 jars of jam and 3 packages of bread mix are in gift basket

Solution:

Let "x" be the number of jars of jam

Let "y" the number of packages of bread mix

Cost of 1 jars of jam = $ 6

Cost of 1 package of bead mix = $ 5

There are 8 items in the basket

Therefore,

number of jars of jam + number of packages of bread mix = 8

x + y = 8 ---------- eqn 1

A gift basket that contains jars of jam and packages of bread mix costs $45

Therefore, we frame a equation as:

number of jars of jam x Cost of 1 jars of jam + number of packages of bread mix x Cost of 1 package of bead mix = 45

$x \times 6 + y \times 5 = 45$

6x + 5y = 45 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 8 - y --------- eqn 3

Substitute eqn 3 in eqn 2

6(8 - y) + 5y = 45

48 - 6y + 5y = 45

y = 48 - 45

Substitute y = 3 in eqn 3

x = 8 - 3

Thus 5 jars of jam and 3 packages of bread mix are in gift basket

One year I had 30 ap environmental science students and the next year I had 50 environmental students, what percentage did the p

stich3 [128]

If you want to find by how much percent something increased, take the final value and divide it by the initial value. When you divide 50 by 30, you get 5/3, which can be written as 1.666(repeating). Then, you subtract 1 from the answer and multiply by 100. So, the population of APES students grew by 66.66%
