Mathematics

Answer:

Greater than 9 hours.

Step-by-step explanation:

Company A annual fees = $125

Company A share fee = $5 per hour

Let number of hour be x, then

Company A total fee = $125 + 5x

Similarly, Company B annual fees = $80

Company B share fee = $10 per hour

Let number of hour be x, then

Company B total fee = $80 + 10x

If company A is a better deal, then

125 + 5x < 80 + 10x

= 125 - 80 < 10x - 5x

= 45 < 5x

= x > 45÷ 5

= x > 9

So, number of hours must be greater than 9 hours.

Estimate the total percentage of complaints about parking difficulties and the location of the store. (nearest whole percent)

AysviL [449]

Answer:

Therefore the total Complains about parking difficulties=32.26%

Therefore the total Complains about the location of the store=25.81%

Step-by-step explanation:

Given ,

Complains about difficulty parking = 250

Complains about isolated location = 200

Complains about ruled sales clerks=150

Complains about too expensive=125

Complains about confusing layout= 50

Total complains = (250+200+150+125+50)

=775

Therefore the total Complains about parking difficulties

= $\frac{250}{775}\times 100$ %

=32.26%

Therefore the total Complains about the location of the store

$=\frac{200}{775}\times 100$ %

=25.81%

Using a calculator with the binompdf and binomcdf features, I can calculate these values. My calculator is a TI-83 plus, and the features are found under the 2nd, Vars keys (Scroll up or down until you see them).

If "exactly" is to be found, use binompdf:
binompdf(number of trials, probability of success, exactly number)

ANSWER for exactly 3: binompdf(8, 0.5, 3) = 0.21875 = 21.875%

If "at least" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at least number - 1)

ANSWER for at least 6: binomcdf(8, 1/2, 5) ≈ 0.8555 ≈ 85.55%

If "at most" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at most number)

ANSWER for at most 3: binomcdf(8, 0.5, 3) ≈ 0.3633 ≈ 36.33%

Find the 13th term of the arithmetic sequence -3x+7, -5x+3, -7x-1, ...

oksano4ka [1.4K]

Answer:

a₁₃ = - 27x - 41

Step-by-step explanation:

The nth term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3x + 7

d = a₂ - a₁ = - 5x + 3 - (- 3x + 7)

= - 5x + 3 + 3x - 7

= - 2x - 4

Then

a₁₃ = - 3x + 7 + 12(- 2x - 4)

= - 3x + 7 - 24x - 48

= - 27x - 41
