Which Transformation Results In The Function, I Would Also Like A Explanation On How To Do This.

Answers

Answer 1

The transformation that is results in the given function is a horizontal shrink of scale factor 1/4.

Which transformation results in function g(x)?

Remember that for a function f(x), we define a horizontal shrink of scale factor k as:

g(x) = f(x*1/k)

Here we know that:

f(x) =x^2

g(x)= f(4x) = (4x)^2

Then this is equivalent to an horizontal shrink of scale factor of 1/4

Then the scale factor is k = 1/4, and the correct option is A.

Suppoe that the concentration of a bacterial ample i 100,000 bacteria per millimeter. If the concentration double every three hour how long will it take for the concentration to reach 350,000 material per millimeter?

Answers

The time t = 3.4209 will it take for the concentration to reach 350,000 material per millimeter.

How do you calculate hours and minutes?

In an hour, there are 60 minutes. Divide the number of minutes by 60 to convert it to hours. For instance, 120/60=2 means that 2 hours are equal to 120 minutes.

What is millimeter?

The millimeter, abbreviated mm in the International System of Units (SI), or millimeter, abbreviated mm in the American spelling, is a unit of length that is one thousandth of a metre long, the SI base unit of length. As a result, a metre is made up of 1000 millimeters.

We are going to use formula

y = a * e ^ (b * t)

a and b are constants and t is for time.

Initially there are 100,000 bacteria, so;

100000 = a * e ^ (b * 0)

100000 = a * 1

a = 100000

given condition is that the concentration doubles every 3 hours so

300000 = a * e ^ (b * 3)

As a equals to 100,000

e ^ (b * 3) = 3

b * 3 = ln 3

b = (ln 3) / 3

b = 0.3662

now we have to find value of the time when concentration of bacteria reaches to 350,000:

350000 = 100000 * (e ^ 0.3662 * t)

3.5 = e ^ 0.3662* t

ln 3.5 = 0.3662* t

t = 1.2527 / 0.3662

t = 3.4209

That is the required value of time

The results of a series of surveys revealed a population with a mean of 15 and a standard deviation of 1.88. If each survey has a sample size of 70, which value falls within the interval where 95% of the sample means occur?
A) 15.66
B) 15.49
C) 14.96
D) 14.34

Answers

If each survey has a sample size of 70, a value which falls within the interval where 95% of the sample means occur is: C) 14.96.

What is a confidence interval?

In this scenario, the confidence interval at 95% can be represented by this mathematical expression p - E < p < p + E

Based on the parameters provided, we would determine both the lower limit and upper limit for the interval where 95% of the sample means occur as follows;

Lower limit = 15 - 1.88/√70

Lower limit = 15 - 0.23

Lower limit = 14.77

For the upper limit, we have:

Upper limit = 15 + 1.88/√70

Upper limit = 15 + 0.23

Upper limit = 15.23

For 95% of the sample means to occur, the confidence interval is given by;

What is the equation on the graph?

We can see that we have a linear equation on the graph, remember that a general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

On the graph, we can see that the line intercepts the y-axis at y = 4, then the y-intercept is b = 4

y = a*x + 4

To find the slope we can use another point on the line, for example, we can see that (-6, 0) is also on the line, replacing these values in the linear equation above we will get:

through (4,-9) perpendicular to 8y=x-16

Answers

Answer:

y = -8x + 23

Step-by-step explanation:

8y=x-16

we need to turn this into slope-intercept form by dividing 8 on both sides

y = x/8 - 2

to make a line perpendicular from another, we must make sure the slope is the negative reciprocal of the original line.

Right now, it's the same as the original. To make it a negative reciprocal, switch the places of the denominator and numerator and flip the signs

-8x is the negative reciprocal of x/8

Does it go through (4,-9)? No.

To make sure it goes through 4,-9, we change it's y-intercept.

Plug in the coordinate given (4,-9) in the y = -8x + b ( we removed -2 since it's not the right answer.

y = -8x + b

(-9) = -8(4) + b

-9 = -32 + b

-9 +32= -32 + b +32

23 = b

plug in b and we get our answer

y = -8x + 23

Fail to reject the null hypothesis. The​ P-value is greater than the level of significance.

Candice should reject the null hypothesis as the 50% confidence interval does not contain 10 hours

Small p-values offer proof that the null hypothesis is false. The stronger the evidence is against the null hypothesis, the smaller (closer to 0) the p-value. The null hypothesis is rejected if the p-value is less than or equal to the chosen significance level; otherwise, it is not.

You have the Hypothesis that "students study less than 10 hours, on average, per week"

Symbolically:

H₀:μ≥10hours

H₁:μ<10hours

The significant level for this case study is 50% - 0.05. If the results gotten is less than the significance level, we reject the null hypothesis, but if greater, we fail to reject the null hypothesis.

The p-value of 0.05 is one of the most often used numbers. When the calculated p-values are less than 0.05, the faulty hypothesis is considered to be fraudulent or invalid (subsequently the name invalid theory). Additionally, the faulty theory is taken into consideration to be clear if the value is greater than 0.05.

The edge for that likelihood in our model is 0.05, and it represents the probability that our results will be similar to the invalid speculation. Therefore, if the calculated p-value is less than 0.05, it actually means that there is a very little likelihood that we would have the same results as the flawed hypothesis. Additionally, if the p-value is greater than 0.05, there is a very strong probability that the results will be similar to the flawed speculation, leading us to conclude that it is legitimate.
