Answer:

The answer is 3/4

Step-by-step explanation:

When you divide two fractions, such as 1/2 ÷ 2/3, you have to flip the second fraction and then you simply multiply the numerators with each other and the denominator with each other.

The range of the function is 0 ≤ y ≤ 8.

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

From the graph,

The y coordinate values are the range of the function.

Now,

We see that,

The y-coordinate is from 0 to 8.

So,

The range is 0 ≤ y ≤ 8

Thus,

The range is 0 ≤ y ≤ 8

Answer:

x=37

Step-by-step explanation:

By Vertical Angles Theorem (VAT), (4x+2) is equal to 150º, so then you just subtract 2 from both sides of the equation 4x+2 = 150, to make it 4x = 148, and then divide both sides by 4 to isolate x, and then you get x=37.

The given function with a constant rate of change that equals -3 is: 2y = -6x + 10.

The constant rate of change of a function = change in y / change in x. Given an equation of a function in slope-intercept form, y = mx + b, the constant rate of change is represented as m.

1. Constant rate of change of the function on the table using two pairs of values, (0, 2) and (1, 5) is:

(5 - 2)/(1 - 0) = 3/1

Constant rate of change = 3.

2. Constant rate of change of the function of the set of ordered pairs  using two pairs of values, (4, 4) and (2, 2) is:

(4 - 2)/(4 - 2) = 2/2

Constant rate of change = 1.

3. Constant rate of change of the graphed function using two points on the line, (1, 1) and (0, 3) is:

(3 - 1)/(0 - 1) = 2/-1

Constant rate of change = -2.

4. Constant rate of change of the function 2y = -6x + 10:

Rewrite the equation in slope-intercept form

2y/2 = -6x/2 + 10/2

y = -3x + 5

Constant rate of change = -3.

Therefore, the function with a constant rate of change is: 4. 2y = -6x + 10

i dont know if this is correct or not tho

If the function g is related to one of the parent functions. g(x)= -(x-2)^3. the function notation to write g in terms of f will be -x³.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that the function is,  g(x)= -(x-2)^3

Expand the given function we get,

g(x)= -(x³-3×x²×2+3×x×2²-2³)

g(x)= -(x³-6x²+12x-8)

g(x)= -x³+6x²-12x+8

The parent role of a family is recognized as the most basic function of a family and serves as the definition of the complete family, as we all know. Additionally, we are aware that the parent function for functions of the kind f(x)=ax²+bx+c

Thus, if the function g is related to one of the parent functions. g(x)= -(x-2)^3. the function notation to write g in terms of f will be -x³.

Answer: 70, 130

Step-by-step explanation:

In the given normal distribution with a mean of 100 and standard distribution of 15, 95% of values will fall between 70 and 130 using the Empirical rule of 95%.

Step-by-step explanation:

A normal distribution with a mean of 100 and a standard distribution of 15 is given.

We will find where 95% of data fall in the given normal distribution.

It states that in a normal distribution approximately 95% of observations fall within two standard deviations from the mean on both sides of the normal curve.

The mean in a normal distribution is the center of the normal curve.

The standard deviation in a normal distribution is the distance from the mean to the required point on either side.

We have,

Mean = 100

Standard deviation = 15

Applying the 95% rule we get,

On the right side of the normal curve

Mean + 2 x standard deviation = 100 + 2x 15 = 100 + 30 = 130.

On the left side of the normal curve,

Mean - 2 x standard deviation  = 100 - 2x15 = 100 - 30 = 70.

Thus, we see that by using the Empirical rule of 95%, 95% values will fall between 70 and 130.

Answer:

B: Gabriel's

Step-by-step explanation:

Answer:

6 mins

Step-by-step explanation:

Given that;

T(t) = Ce^-kt + T(s)

Since T(t) = 200◦F, and T(s) = 70◦F where t = 0

200= Ce^-k(0) + 70

C= 200 - 70

C = 130

Then when T(t) = 190◦F and t= 1s ;

190 = 130e^-(k *1) + 70

190 - 70 = 130e-^(k *1)

120/130 = e^k

0.923 =  e^-k

-k = ln(0.923)

k = 0.08

To determine the time taken to reach a temperature of  150◦F

150 = 130e^-(0.08t) + 70

150 - 70/130 = e^-(0.08t)

0.6154 = e^-(0.08t)

-(0.08t) = ln 0.6154

0.08t = 0.4855

t = 0.4855/0.08

t = 6 mins

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: She does not have a heart attack.

Event B: tests predicts that she will have a heart attack

The doctors told her that the reliability of the stress test is 67%.

This means that there is a 100 - 67 = 33% of not having a heart attack if the test predicts she will have a heart attack, so:

[tex]P(B|A) = 0.33[/tex]

70% risk of heart attack

So 100 - 70 = 30% probability of not having a heart attack, which means that [tex]P(A) = 0.3[/tex]

What is the probability that Erin will not have a heart attack and the test predicts that she will?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(B|A)*P(A) = 0.33*0.3 = 0.099[/tex]

The correct answer is given by option A.

Answer:

  W(x) = 27/256(x)(32-x)

Step-by-step explanation:

There are several ways you can do this. The method we've used here is to write a function that has zeros at x=0 and x=32, opens downward, and has a maximum at x=16 of 27.

The zeros give rise to the factored form ...

  w = x(x -32)

To make it open downward, we need to reflect this across the x-axis. We can add a leading minus sign, or we can swap the terms in the binomial that has a minus sign:

  w = -x(x -32) = x(32 -x)

This will have a value of 16(32 -16) = 256 at its peak. We want the peak to be 27, so we can vertically scale this function by a factor of 27/256. The grap attached shows this gives the desired result.

  W(x) = (27/256)(x)(32-x)

It says to determine the null and alternative hypothesis

H0 is mean1=mean2=mean3

H1 is at least one of the three population mean is different from the others

It says find the F test stat

You need some form of a TI-84 plus calculator. From there, you take the data from the King-Size nicotine (mg) in List 1. 100mm-Menthol in List 2. 100-mm nonmenthol in List 3. From there you go to STAT then hit TEST then scroll all the way to the bottom where it says AVOVA. Click enter, from there you see ANOVA(, from there you have to tell it where the lists are. after ANOVA(, put L1, L2,L3 (assuming that's where you put your data into) so when all said and done in your calculator, it should look something like this: ANOVA(L1, L2, L3) then hit enter. The first line where it says F=, that's your test stat.

Find the P value:

You find the P value in the same menu as your test stat. It should be the number right below your test stat. P=

What is the conclusion for this hypothesis ?

Since our P value is less then alpha, we reject the null hypothesis (H0). From there we can conclude that there IS SUFFICIENT evidence to warrant rejection of the claim that the three categories of cigarettes yield the same mean amount of nicotine

Do the filters appear to make a difference?

Given that the king-size cigarettes have the largest mean, it appears that the filters do make a difference

Step-by-step explanation:

The king-size cigarettes have the largest mean, it appears that the filters do make a difference.

There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test.

The hypothesis which we put against null hypothesis is alternate hypothesis.

Null hypothesis is the one which researchers try to disprove.

H1 is at least one of the three population mean is different from the others.

To find the P value in the same menu as your test stat. It should be the number right below your test stat.

The conclusion for this hypothesis, Since our P value is less then alpha, we reject the null hypothesis (H0).

From there we can conclude that there is a sufficient evidence to warrant rejection of the claim that the three categories of cigarettes yield the same mean amount of nicotine.
