Phoenix [80]

Answer:

Malcolm’s debt-to-income ratio is 0.8125

Step-by-step explanation:

we know that

To find out Malcolm’s debt-to-income ratio, divide monthly expenses by the monthly salary

Let

x ------> Malcolm’s monthly expenses

y -----> Malcolm’s monthly salary

In this problem we have

$x=\$975\\ y=\$1,200$

The ratio is equal to

$975/1,200=0.8125$

5+25+125+625+3125+15625 rewrite each series using sigma notation

Trava [24]

1. You have that the series is: 5+25+125+625+3125+15625
2. You must find the ratio (r) between the adjacent members. Then, you have:

25/5=5
125/25=5
625/125=5
3125/625=5
15625/3125=5

3. Therefore, the ratio is:

r=5

4. Then, each term has te form 5^k. So, you have:

5^1=5
 5^2=25
 5^3=125
 5^4=625
 5^5=3125
 5^6=15625

5. As you can see, "k" goes from 1 to 6.

6. The answer is shown in the image attached.

Sixty-five percent of employees make judgements about their co-workers based on the cleanliness of their desk. You randomly sele

Serhud [2]

Answer:

The outcomes of this binomial distribution that would be considered unusual is {0, 1, 2, 8}.

Step-by-step explanation:

The outcomes provided are:

(A) 0, 1, 2, 6, 7, 8

(B) 0, 1, 2, 7, 8

(D) 0, 1, 2, 8

Solution:

The random variable X can be defined as the number of employees who judge their co-workers by cleanliness.

The probability of X is:

P (X) = 0.65

The number of employees selected is:

n = 8

An unusual outcome, in probability theory, has a probability of occurrence less than or equal to 0.05.

Since outcomes 0 and 1 are contained in all the options, we will check for X = 2.

Compute the value of P (X = 2) as follows:

$P(X=2)={8\choose 2}(0.65)^{2}(0.35)^{8-2}$

$=28\times 0.4225\times 0.001838265625\\=0.02175\\\approx 0.022$

So X = 2 is unusual.

Similarly check for X = 6, 7 and 8.

P (X = 6) = 0.2587 > 0.05

X = 6 not unusual

P (X = 7) = 0.1373 > 0.05

X = 7 not unusual

P (X = 8) = 0.0319

X = 8 is unusual.

Thus, the outcomes of this binomial distribution that would be considered unusual is {0, 1, 2, 8}.

Noah thinks the answers to these two questions will be the same. This year, a herd of bison had a 10% increase in population. If

Shalnov [3]

The answer to these two questions are not the same. We don't agree with Noah.

Reason:

Let's start with the first question.

1. Given: rate = 10% increase, base/original number = 550 bison

10% of 550 is:

$.10\times550bison=55bison$

10% of 550 is 55. Hence, there is an increase of 55 bison this year. This year, there are 550 + 55 = 605 bison in the herd.

2. Given: rate = 10% decrease, percentage/final number = 550 bison

Applying the concept of Percentage = Base x Rate, we can get the Base or the original number of bison before the decrease by dividing Percentage over Rate.

$\text{Base}=\frac{\text{Percentage}}{\text{Rate}}$

Filling in the formula with the given values in question 2, we have:

$\text{Base}=\frac{550}{1-.10}=\frac{550}{.90}=611.11\approx611bison$

Last year, there were 611 bison.

As we can see, the answer for number 1 is 605 bison while the answer for the number 2 is 611 bison. The answer of the two questions are not the same.
