Alana has $80 in a savings account. The interest rate is 5% per year and is not compounded. How much interest will she earn in 1 year?

**Answer:**

Answer:

I = $ 1,937.50

**Step-by-step explanation:**

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.875%/100 = 0.03875 per year,

then, solving our equation

I = 10000 × 0.03875 × 5 = 1937.5

I = $ 1,937.50

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 3.875% per year

for 5 years is $ 1,937.50.

I hope this is correct and hope it helps!

According to a survey conducted by the technology market research firm The Radicati Group, U.S. office workers receive an average of e-mails per day (Entrepreneur magazine website). Assume the number of e-mails received per hour follows a Poisson distribution and that the average number of e-mails received per hour is five. a. What is the probability of receiving no e-mails during an hour (to 4 decimals)

**Answer:**

**the probability is 0.0067**

**Step-by-step explanation:**

The computation of the probability of receiving no e-mails during an hour is shown below;

Let us assume x be the number of emails received during an hour

Now the probability of receiving no e-mails is

= e^-5 × 5^0÷ 0!

= e^-5 × 1 ÷ 1

= e^-5

= 0.00674

= 0.0067

Hence, **the probability is 0.0067**

You recently obtained a job with a sports analytics firm, and your first assignment is to write a report evaluating early evidence behind predictions for the 2019-20 NBA season. You will use your knowledge of hypothesis testing to assess the predictions. When conducting a hypothesis test for the population mean, you will not know the population standard deviation, so you will have to use the sample standard deviation instead. How will this affect the process

Answer:

It will affect the process in the sense that the sample population size will be unknown due to the fact that we don't know the population standard deviation.

Step-by-step explanation:

We are told that you do not know the population standard deviation. Thus, the sample population will not be able to be calculated because this sample standard deviation given will not suffice and we need the population standard deviation to be able to calculate the sample population size.

The absence of population **standard** **deviation** will result in **performing** the one mean** t test**. The one **mean** **t test **gives an insight of the **deviation** of **values** from the **mean**.

For the **approval** or **rejection** of the **null** **hypothesis**, hypothesis testing has been performed. For performing a test, a hypothesis has been assigned based on the results we wish to obtain. The **rejection** of **null** **hypothesis** leads to **acception** of the **alternate** **hypothesis**, while the **approval** of the **null** **hypothesis** results in the **rejection** of the **alternate** **hypothesis**.

For performing the **null** **hypothesis** test, there has been the first step to be the requirement of the hypothesis. The **hypothesis** has been **tested** based on the **population** **size**. And the **test** has been **performed**.

The absence of population **standard** **deviation** will result in performing the one** mean t test**.

The one** mean t test** gives an insight of the **deviation** of values from the **mean**. It has been used for the determination of **random** data **sample**, **normal** distribution, **range** of **sampling**.

the manager of a local recreational center wanted to determine the average amount each consumer spent on traveling to and from the center. on the basis of the findings, the manager was planning on setting the entrance fee. the management noted that customers living at the other side of town had to travel about 15 miles and spent about 20 cents per mile. the manager wanted to be 95% confident of the findings and did not want the margin of error to exceed /- 10 cents. what sample size should the manger use to determine the average travel expenditure

**Answer:**

The manager should use a sample size of 12 to determine the average travel expenditure

**Step-by-step explanation:**

**Spent about 20 cents per mile. Distance of 15 miles**

We have the mean per a distance, so we use the Poisson distribution. In this distribution, the standard deviation is the square root of the mean. So

[tex]\mu = 20*15 = 300, \sigma = \sqrt{300} = 17.32[/tex]

**Confidence interval:**

We have that to **find **our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

**Now**, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

**Now, find the margin of error M as such**

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

**What sample size should the manger use to determine the average travel expenditure?**

This is n for which M = 10. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]10 = 1.96\frac{17.32}{\sqrt{n}}[/tex]

[tex]10\sqrt{n} = 1.96*17.32[/tex]

[tex]\sqrt{n} = \frac{1.96*17.32}{10}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*17.32}{10})^2[/tex]

[tex]n = 11.52[/tex]

Rounding up

The manager should use a sample size of 12 to determine the average travel expenditure

at time t, the position of a body moving along the s-axis is s=t^3 - 12t^2 + 36t m. Find the total distance traveled by the body from t=0 to t=3.

**Answer:**

27 m

**Step-by-step explanation:**

The position of a body is given by :

[tex]s=t^3 - 12t^2 + 36t[/tex]

We need to find the total distance traveled by the body from t=0 to t=3.

At t = 0,

[tex]s=0^3 - 12(0)^2 + 36(0)=0\ m[/tex]

At t = 3 s,

[tex]s=(3)^3 - 12(3)^2 + 36(3)\\\\=27\ m[/tex]

**So, the total distance from t=0 to t=3 is equal to 27 m.**

The sum of x and y is 280. If x + 8 is y, when will the value of x be the same for both equations?

**Answer:**

x = 136, y = 144

**Step-by-step explanation:**

x+y = 280

y = x +8

use substitution

x + x+8 = 280

2x = 272

x = 136

y= 136+8 = 144

**Answer:**

the answer is x=136

**Step-by-step explanation:**

x + y = 280

x + 8 = y (substitute this expression for y)

x + (x + 8) = 280

2x + 8 = 280

2x = 272 -> **x = 136**

*to find y:*

x + 8 = y

136 + 8 = y

144 = y

**CHECK: **

136 + 144 = 280

1. Sam rolls a fair dice and flips a fair

coin. What is the probability of

obtaining an odd number and a head?

Use a sample space diagram to help.

See below for an example.

**Answer:**

Mark brainliest pls

**Step-by-step explanation:**

People have given you correct answers but not explained why, perhaps because it seems so obvious.

One of Bayes laws of probability says that if two events e1 and e2 are independent (unrelated), then the probability of both happening together is the product of their individual probabilities.

The die and the coin are independent events. Each is a 50% chance (odd number on a die, heads on a coin). Thus the probability of both happening together is 50% * 50% = 25%.

The **probability **of obtaining an odd number and a head is **1/4.**

**Probability** deals with the occurrence of a random **event**. The chance that a given **event **will occur. It is the measure of the **likelihood **of an **event** to occur.The value is expressed from zero to one.

For the given situation,

Let A be Sam rolls a fair dice.

**Sample space**, s = { [tex]1,2,3,4,5,6[/tex] }

⇒ [tex]n(s)=6[/tex]

An **event **A is obtaining an odd number, e = { [tex]1,3,5[/tex] }

⇒ [tex]n(e)=3[/tex]

The **probability **of A is obtaining an odd number,

[tex]P(A)=\frac{n(e)}{n(s)}[/tex]

⇒ [tex]P(A)=\frac{3}{6}[/tex]

⇒ [tex]P(A)=\frac{1}{2}[/tex]

Now, let B be Sam flips a fair coin.

**Sample space**, s = { [tex]H,T[/tex] }

⇒ [tex]n(s)=2[/tex]

An **event **B is getting a head, e = { [tex]H[/tex] }

⇒ [tex]n(e)=1[/tex]

The **probability **of B is getting a head,

[tex]P(B)=\frac{1}{2}[/tex]

Both A and B are independent **events**.

Thus the **probability **of obtaining an odd number and a head is

[tex]P(e)= P(A)P(B)[/tex]

⇒ [tex]P(e)=(\frac{1}{2})( \frac{1}{2} )[/tex]

⇒ [tex]P(e)=\frac{1}{4}[/tex]

Hence we can conclude that the **probability **of obtaining an odd number and a head is **1/4.**

what is x

**Answer:**

**Step-by-step explanation:**

To solve this problem, isolate the value of x from one side of the equation.

First, switch sides.

-29=x+8

x+8=-29

Then, subtract by 8 from both sides.

x+8-8=-29-8

Solve.

-29-8=-37

x=-37

The domain of y = f(x) = _ is

(a) R - {0}

(b) R

(c) (-2,1)

(d) (-1.1)

the correct answer is b

**Answer:**

The domain of a function is the set of all possible x values that satisfy the equation. We cannot answer this question without first knowing what the equation for f(x) is.

**Step-by-step explanation:**

Take for example the function y = f(x) = [tex]x^{2} +3[/tex]. Here, you can plug in literally any value for x and still get our a real number. Thus, the domain of f(x) is (-∞, ∞).

However, if your function is y = f(x) = [tex]\frac{2}{\sqrt{x+3} }[/tex] , not every x value is acceptable. First, we cannot have the denominator (bottom part) of the fraction be zero, because division by zero is undefined. Thus, x = -3 is not an acceptable value for x.

We also cannot take the square root of a negative number. Thus, we have the rule that x + 3 must be greater than or equal to zero.

[tex]x+3 > 0\\\\x > -3\\[/tex]

Normally we would use greater than or equal to zero, but because this is in the denominator, we don't want it to equal zero (and thus x = -3 is not acceptable).

So, the domain of x is (-3, ∞). The parenthesis tell us we do not include the negative three and we do not include infinity. In other words, the domain of x is all numbers greater than -3 but less than infinity.

So, first look at your equation for f(x), then see which values of x don't break the rules of math like division by zero or square roots of negative numbers. Good luck!

The number N of bacteria present in a culture at time t (in hours) obeys the equation N = 1000e^0.01t After how many hours will the population equal 1500? 2000?

Answer: N(t) = (2^t)*1500

Step-by-step explanation:

Let's define the hour "zero" as the initial population.

So if N(t) is the number of bacteria after t hours, then:

N(0) = 1500.

Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1

N(1) = 2*1500 = 3000

after two hours, at t = 2.

N(2) = 2*(2*1500) = (2^2)*1500

After three hours, at t = 3

N(3) = 2*(2^2)*1500 = (2^3)*1500

So we already can see the pattern, the number of bacteria after t hours will be:

N(t) = (2^t)*1500
