In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment the mass of the substance was 1000 grams and mass was decreasing by 14% per day. Determine the mass of the radioactive sample at the beginning of the 10th day of the experiment. Round to the nearest tenth (if necessary).​

Answers

Answer 1

Answer:

120.91 grams

Step-by-step explanation:

multiply the initial amount by the percent that will remain to the power of n-1, n being the term number, or how many days that have passed.

f(x)=1000(0.85)^14-1

Cheyenne's car is in the shop, so she needs to rent a car for 4 days. The cost of a rental car is $24.99 per day, and she will be charged $0.18 per mile for every mile she drives over 200 miles. If she drives 300 miles and the sales tax she pays on the rental is 5.5%, how much will she pay for this rental?

Answers

Answer:

22.99

Step-by-step explanation:

Well, $24.99 dollars no matter how many miles. if she drove 200 miles, we will say that x represents miles driven. So, the cost will be $24.99+ $0.10x

to solve, substitute 20 for x.

$24.99 + $0.10(20)

$24.99 + $2

$24.99

Your answer is 22.99 dollars!

A medical device company knows that 11% of patients experience injection-site reactions with the current needle. If 3 people receive injections with this type of needle, what is the probability that the first person has an injection-site reaction, but the next two do not?

Answers

Answer:

0871

Step-by-step explanation:

 

Using geometric distribution, the probability that the first person has an injection-site reaction, but the next two do not is 0.087131.

What is geometric distribution?

Geometric distribution is "a  discrete probability distribution that represents the probability number of successive failure before a success obtained in a Bernoulli trial".

According to the question,

Patients experience injection-site reactions with current needle is 11%.

Number of people receive injections with this type of needle is 3.

The probability mass function of Geometric distribution (PMF) is given as

[tex]P(1 - p)^(x-1)[/tex].

P = 11 % = 0.11

In order to find the probability that the first person has an injection-site reaction, but the next two do not

= [tex]0.11(1-0.11)^(3-1)[/tex]

= [tex]0.11(0.89)^2[/tex]

=0.11(0.7921)

=0.087131

Hence, using geometric distribution, the probability that the first person has an injection-site reaction, but the next two do not is 0.087131.

Given m \| nm∥n, find the value of x.

Answers

Answer:

x=32

Step-by-step explanation:

If you do 2x-16+4x+4=180, then you should get 32.

The value of x is 32.

Given,

The m line is parallel with the n line.

We need to find the value of x.

What are the relationships between parallel lines and angles?

If two lines are parallel the corresponding angles are congruent.

Example:

                               

                          D /

                           /

A<----------------F/----------------------->B

                       /

C <-----------M/------------------------------>D                    

                   /

             E  /

AFD = CMF

AFM = CME

From the figure, we see that

2x - 16 + 4x + 4 = 180

6x - 12 = 180

6x = 180 + 12

6x = 192

x = 192/6

x = 32

Thus the value of x is 32.
