B(n)=4-6(n-1) find the fourth term

Answers

Answer 1

Answer:

Answer:

b(4) = -14

Step-by-step explanation:

b(n)=4-6(n-1)

let n=4

b(4) = 4 - 6(4-1)

b(4) = 4-6*3

b(4) = 4-18

b(4) = -14

Answer:

The correct answer is A,G,E

Final answer:

The center is closer to 14, the peak is at 14, the plot is skewed to the left, the spread is from 10 to 15, and the person waited for the bus 16 times which indicate the number of dots or data entries on the dot plot.

Explanation:

From the provided description, we can make several determinations about the dot plot. The center would represent the typical or median value. Because the data is divided in such a way that 11 is to the left and 14, we can observe that the center is somewhat closer to 14 than it is to 13. Therefore, the accurate statement would be that 'The center is 14' rather than 'The center is 13.'

The peak of the dot plot is the value with the greatest frequency, which is the number that has most dots associated with it. As mentioned in the question, 14 has 6 dots, which is the highest count, so it's accurate to say that 'The peak is at 14.'

The plot doesn’t have two even groups of data, hence the statement 'It has two clusters' is incorrect. Also, since the majority of the data points or dots are towards the right-hand side, it's more accurate to say that this plot is skewed left. The spread of the data is actually from 10 to 15, not from 13 to 15. Lastly, by counting the total number of dots which represent the number of days, it is accurate to say 'The person waited for the bus 16 times'.

i think the answer is D because its multiplying by 2 each time

D) 2, 4, 8, 16, 32

Explanation:

In order for it to be a geometric sequence, it has to be multiplied by the same number every time. The only equation that demonstrates this is the last one since it is being multiplied by 2 every time.

The geometric sequence equation is
A(n) = a* r^{n-1}
a( n ) = term in the sequence
a = first term
r = common ratio (what it's multiplied by every time)

Cost of a store is $80 and the Mark-Up price is 60% what is the Sale Price?

Answers

The markup price = 60/100 * 80 = 48.00 $

The sale price = 80.00 + 48.00 = 128.00 $

An employee earned $56,700.00 in a year and had $8,788.50 withheld for federal income tax. What federal income tax percent was withheld? if necessary, round your answer to the nearest hundredth of a percent.

Answers

so earned 56,700 in a year and had 8,788.5 held back
convert to percent

so find what percent was withhelald which is (amount held back)/(total taken from)
so it would be 8,788.5/56,700=0.155/1
percent means parts out of 100 or x/100=x% so convert the bottom number ot 100 by mulitplyint the whole fraction by 1 or 100/100 so
0.155/1 times 100/100=15.5/100=15.5%
the answer is 15.5%

Monte performs an experiment using 2 identical graduated cylinders with a radius of 2 cm. The volume of the liquid in the first graduated cylinder is 188.4 cm3. The volume of the liquid in the second graduated cylinder is 314 cm3.What is the difference in the height of the liquid in the two cylinders?

Use 3.14 to approximate pi.

Answers

Answer:

The difference of height is 10 cm

Step-by-step explanation:

Monte performs an experiment using 2 identical graduated cylinders with a radius of 2 cm.

The volume of the liquid in the first graduated cylinder is 188.4 cm³

The volume of the liquid in the second graduated cylinder is 314 cm³

Let height of first graduated cylinder be h₁ and radius (r) = 2 cm

Let height of second graduated cylinder be h₂ and radius (r) = 2 cm

Formula:

$\text{Volume of cylinder}=\pi r^2h$

$\text{Volume of 1st cylinder}=\pi\cdot 2^2h_1$

$188.4=3.14\cdot 2^2\cdot h_1$

$h_1=15$ cm

$\text{Volume of 2nd cylinder}=\pi\cdot 2^2h_2$

$314=3.14\cdot 2^2\cdot h_2$

$h_2=25$ cm

The difference in the height of the liquid in two cylinder,

$\Rightarrow h_2-h_1$

$\Rightarrow 25-15$

$\Rightarrow 10$ cm

Hence, The difference of height is 10 cm

Volume of a cylinder of radius r, height h : $V=\pi*r^2*h$

hence the height of the liquid in the first cylinder is $h1=(188.4)/(2^2\pi)=15$ cm, and in the second cylinder $h2=(314)/(2^2\pi)=25$ cm

Hence the difference is h2-h1=25-15=10 cm
