Thats called an expression, the answer is just that because there is no answer considering you can't add or subtract from a variable because they are not alike...

Write the set of real numbers x less than 6 in set builder notation

maksim [4K]

Answer:

{x ∈ R: x<6}

Step-by-step explanation:

Given

x is a real number
x is less than 6

Required

Write the set using set builder notation

The very first thing to do is to list out the range of x, using inequalities;

x is less than 6 implies that -infiniti < x < 6

The next step is to translate this to set builder. This is done as follows

x ∈ R - > This means that x is a real number

x < 6 -> where x is less than 6.

Bringing these two together, it gives:

{x ∈ R: x<6}

Hence, the set of real numbers x less than 6 is equivalent to {x ∈ R: x<6} using set builder notation

A manufacturer is running an experiment using the standard (control) infant formula, and two new formulas, A and B. The goal is

bulgar [2K]

Answer:

H0: the mean IGA score is the same for all three formulas. 

Ha: the mean IGA score is not the same for all three formulas.

The Group of answer choices are as below:

H0: the mean IGA score is the same for all three formulas. 

Ha: the mean IGA score is not the same for all three formulas.

H0: the mean IGA score is the same for all three formulas. 

Ha: the mean IGA score is higher for at least one of the two treatment groups than the control group

H0: the mean IGA score is the same for all three formulas. 

Ha: the mean IGA score is higher for both treatment groups A and B than the control group.

D. No answer text provided.

Explanation:

Given that a manufacturer is running an experiment using the standard (control) infant formula, and two new formulas, A and B to boost the immune system in infants.

The variable that is measured is Total IGA (in mg per dl) score.

We have to state the hypotheses for one-way ANOVA F test to test if the mean IGA score is the same for all three formulas.

In null hypothesis H0, the mean of all groups are equal and in alternative hypothesis, Ha, the mean of the groups are not the same.

Therefore, the hypothesis tested by the one-way ANOVA F test are:

H0: the mean IGA score is the same for all three formulas.

Ha: the mean IGA score is not the same for all three formulas.

For this case we have the following function:
$f (x) = 0.01 * (2) ^ x
$
By definition, the average rate of change is given by:
$AVR = \frac{f(x2) - f(x1)}{x2 - x1}$
We evaluate the function for the given values:
For x = 7:
$f (7) = 0.01 * (2) ^ 7

f (7) = 1.28$
For x = 14:
$f (14) = 0.01 * (2) ^ {14} f (14) = 163.84$
Then, replacing values we have:
$AVR = \frac{163.84 - 1.28}{14 - 7}$
$AVR = 23.22$
Answer:
the average rate of change from x = 7 to x = 14 is:
a. 23.22
