Answer:

  a) see the attached spreadsheet (table)

  b) Calculate, for a 10-year horizon; Computate for a longer horizon.

  c) Year 13; no

Step-by-step explanation:

a) The attached table shows net income projections for the two companies. Calculate's increases by 0.5 million each year; Computate's increases by 15% each year. The result is rounded to the nearest dollar.

__

b) After year 4, Computate's net income is increasing by more than 0.5 million per year, so its growth is faster and getting faster yet. However, in the first 10 years, Calculate's net income remains higher than that of Computate. If we presume that some percentage of net income is returned to investors, then Calculate may provide a better return on investment.

The scenario given here is only interested in the first 10 years. However, beyond that time frame (see part C), we find that Computate's income growth far exceeds that of Calculate.

__

c) Extending the table through year 13, we see that Computate's net income exceeds Calculate's in that year. It continues to remain higher as long as the model remains valid.

Answer:

0.076 ; 1.924

Step-by-step explanation:

Given that :

_______Downtown Store ___ North Mall Store

n _______25 _______________20

Mean (m) _ $9 _______________$8

Sample sd_ $2 ______________$1

Standard Error (SE) = √[(s1²/n1) + (s2²/n2)]

√((2^2/25) + (1^2/20)) = 0.4582575

df = (25 + 20) - 2= 43

(m2 - m1) ± t(df = 43 , 0.025) * SE

(9 - 8) ± 2.01669 * 0.4583

(1 - 0.9242) ; (1 + 0.9242)

Answer:

We conclude that the two ordered pairs (0, 0) and (-2, 2) are the solutions of the equation y = 2x² + 3x.

Step-by-step explanation:

Given the expression

y = 2x² + 3x

Substituting x = 0

y = 2(0)² + 3(0)

y = 0+0

y = 0

Thus, the ordered pair is: (0, 0)

Now, substituting x = -2

y = 2x² + 3x

y = 2(-2)² + 3(-2)

y = 8 - 6

y = 2

Thus, the ordered pair is: (-2, 2)

Therefore, we conclude that the two ordered pairs (0, 0) and (-2, 2) are the solutions of the equation y = 2x² + 3x.

Answer:

y = x - 6

Step-by-step explanation:

find slope

m = -2 - (-9) / 4 - (-3)

m = 7 / 7

m = 1

find y intercept using slope formula

y = mx + b and plug in any points given

-2 = 1(4) + b

b = - 6

put it together

y = x - 6

Answer: 60%

Step-by-step explanation:

the probability is -2 is less than or equal to x and x is less than or equal to 2 so you would include .33, .16, and .10 in your problem

.33 + .16 + .11 = .6

.6 x 100 = 60

if m=-3

9-m=9-(-3)=9+3=12

Step-by-step explanation:

For the left end of the function, it moves up towards positive infinity.

For the right end of the function, it movea down towarda negative infinity.

Therefore as x approaches -infinity, y approaches +infinity and as x approaches +infinity, y approaches negative infinity. (2nd option)

Answer:

21.759

Step-by-step explanation:

Given that :

Mean (m) = 25

Standard deviation (s) = 12.5

Sample size (n) = 40

α = 90%

The confidence interval is obtained using the relation:

Mean ± Zcritical * s/sqrt(n)

Zcritical at 90% confidence interval = 1.64

25 ± 1.64 * (12.5/sqrt(40))

Lower boundary : 25 - 1.64(1.9764235) = 21.75866546

Upper boundary : 25 + 1.64(1.9764235) = 28.24133454

(21.759, 28.241)

Hence, lower bound of confidence interval is : 21.759

Step-by-step explanation:

Answer:

Santana scored 12 2-point baskets.

Step-by-step explanation:

Given that Santana converted 22 baskets in his last basketball game, totaling 54 points at the end of the game, and that in basketball the baskets are worth 2 and 3 points, to determine the number of baskets of each value that Santana converted, the following logic reasoning must be done:

If all the baskets were 2 points, the total of points made would have been 44 (22 x 2). Now, there are 10 more points, which are attributable to the 3-point baskets (that is, each extra point is a 3-point basket). Therefore, since 54 minus 44 equals 10, Santana made 10 3-point baskets and 12 2-point baskets.

This is verified through the following calculation:

(10 x 3) + (12 x 2) = X

30 + 24 = X

54 = X

I'm not, but free points?

Answer:

[tex]3.10* 10^0[/tex]

Step-by-step explanation:

Given

[tex]3.091403[/tex]

Required

Express in standard form

A number in standard form can be expressed as:

[tex]a * 10^b[/tex]

Where

[tex]1 \leq a \leq 10[/tex]

i.e.

a is between 1 and 10 (inclusive) and preferable, a should be in 2 decimal places

We have that:

[tex]3.091403[/tex] is between 1 and 10.

So, in standard form it is:

[tex]3.091403 * 10^0[/tex]

Approximate to 2 decimal places

[tex]3.10* 10^0[/tex]

Hence, the standard form of [tex]3.091403[/tex] is [tex]3.10* 10^0[/tex]

They will need 4 buses.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

For the class field trip,

the fourth grades at Jefferson Elementary School need to take buses.

Each bus fits 55 students,

and there are 200 students in fourth grade.

The number of buses,

= 200/55

= 3.63

≈ 4.

Therefore, the need is for 4 buses.
