In a lab experiment, 5400 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 4 hours. How many bacteria would there be after 17 hours, to the nearest whole number?

Answers

Answer 1
It will become 45900 bacteria in 17 hours
Step-by-step explanation:
In 4 hours 5400 bacteria becomes 5400*2 = 10800
Therefore in 17 hours, it will become
17*10800/4
= 183600/4
= 45900

b is 30 more than a. b is 6 times as many as a. Find the values of a and b.​

Answers

Answer:

a = 6 and b = 36

Step-by-step explanation:

Set up equations:

b = 30 + a

b = 6a

Subtract the two equations:

b = 6a

- (b = 30 + a)

5a - 30 = 0

5a = 30

divide both sides by 5

a = 6

Plug a = 6 into the original equation:

b = 30 + 6

b = 36

you could also do:

b = 6 * 6

b = 36

The time taken by Nick to do his statistics homework follows a normal distribution with a mean of 25 minutes and a standard deviation of 5 minutes. Jasmin’s homework time also follows a normal distribution with a mean of 50 minutes and a standard deviation of 10 minutes. They hate each other’s guts and never work together so we can assume that Nick’s homework completion is independent of Jasmine’s homework completion.

a) Define the random variable D to be the difference between the amount of time spent on a randomly selected assignment of Jasmin’s and a randomly selected assignment of Nick’s. So D = N – J. Find the mean and the standard deviation of D.

b) Calculate the probability that Nick spent longer doing his assignment than Jasmin did. Show your method clearly.

Answers

Answer:

a) Mean of D = -25

Standard deviation of D = 11.18

b) P(N > J ) = 0.9875

Step-by-step explanation:

Given - μₙ = 25, σₙ = 5 , μₐ = 50 , σₐ = 10

where μₙ is mean of nick and  μₐ is mean of jasmine

 σₙ = 5 is standard deviation of nick and σₐ is standard deviation of jasmine

To find - a) Define the random variable D to be the difference between the      amount of time spent on a randomly selected assignment of Jasmine’s and a randomly selected assignment of Nick’s. So D = N – J. Find the mean and the standard deviation of D.

b) Calculate the probability that Nick spent longer doing his assignment than Jasmine did. Show your method clearly.

Proof -

a)

Mean of D = Mean of nick - Mean of jasmine

                  = 25 - 50 = -25

standard deviation of D = √Standard deviation of Nick + jasmine

                                       = √5² + 10² = √25 + 100 = √125 = 11.18

∴ we get

Mean of D = -25

Standard deviation of D = 11.18

b)

We have to find - P(N > J)

If N > J , then D > 0

Now,

The z-score is expressed as

z = [tex]\frac{0 - (-25)}{11.18} = \frac{25}{11.18} = 2.24[/tex]

Now,

P(N>J) = P (D > 0) = P(Z < 2.24)

                            = 0.9875

⇒P(N > J ) = 0.9875

A circular placemat has 44 inches of braid around the edge. What is the area of the placemat to the nearest square inch? Use 3.14 for π.

Answers

Answer:

153.86 in^3

Step-by-step explanation:

Given data

A circular placemat has 44 inches of braid around the edge

hence the circumference of the placemat is 44 in

C= 2πr

44= 2*3.14r

r= 44/2*3.14

r= 44/6.28

r= 7.00 in

Area= πr^2

Area= 3.14*7^2

Area= 3.14*49

Area= 153.86 in^3

Hence the area is 153.86 in^3

The teacher has told the class that students with a test score in the top 2.5% will win a special prize. Calculate the test score above which 2.5% of all test scores lie. Give your answer to 1 decimal place. Test score

Answers

Answer:

Test score of 75.7.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The results are normally distributed with a mean test score of 60 and a standard deviation of 8.

This means that [tex]\mu = 60, \sigma = 8[/tex]

Calculate the test score above which 2.5% of all test scores lie.

Above the 100 - 2.5 = 97.5th percentile, which is the value of X when Z has a pvalue of 0.975, so X when Z = 1.96.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.96 = \frac{X - 60}{8}[/tex]

[tex]X - 60 = 8*1.96[/tex]

[tex]X = 75.7[/tex]

Test score of 75.7.

What is the similarity?

If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.

If two figures have three sides similar then they will be similar by side-by-side property which is written as SSS.

Given that Triangle R U V. Side V R is 4 centimetres, R U is 1.5 centimetres, and V U is 2.7 centimetres. Triangle R S T. Side R S is 3.0 centimetres, R T is 8.0 centimetres, and S T is 5.4 centimetres.

The two triangles have a common ratio of 2.

R U = 1.5 cm

R S = 3.0 cm

V R = 4 cm

R T = 8.0 cm

Step-by-step explanation:

To find the perimeter of the triangle, you have to add all the sides of the triangle. So, we get:

[tex]P=8\sqrt{x} +7\sqrt{x} +9\sqrt{x}[/tex]

Combine like terms, meaning the numbers with [tex]\sqrt{x}[/tex]

[tex]P=24\sqrt{x}[/tex]

To find the area of the triangle, we will use the formula [tex]A=\frac{1}{2} bh[/tex], where b is the base and h is the height

The base is: [tex]9\sqrt{x}[/tex]

The height is: [tex]8\sqrt{x}[/tex]

For the given functions f and g, find the requested composite function value.
f(x) = x - 8
x , g(x) = x2 + 6; Find ( g H f)(-2).

Answers

Answer:

Step-by-step explanation:

Composite function:

A composite function is represented by:

[tex](g \circ f)(x) = g(f(x))[/tex]

In this question:

[tex]f(x) = x - 8[/tex]

[tex]g(x) = x^2 + 6[/tex]

[tex](g \circ f)(x) = g(f(x)) = g(x-8) = (x-8)^2 + 6[/tex]

Find ( gof)(-2).

When x = -2. So

[tex](g \circ f)(-2) = (-2-8)^2 + 6 = (-10)^2 + 6 = 100 + 6 = 106[/tex]
