How do you identify the opposite and the absolute value of a rational number

Sergeeva-Olga [200]

Rational numbers are the numbers that can be written as the fraction of two integers and absolute value is the distance a number is away from 0. If we look at a number line, the absolute value is the distance any number on the number line is away from 0. Distance is always positive, so our absolute value is always 0.

Is this number written in scientific notation? 33.4 × 10 − 2 Group of answer choices Yes it is in scientific notation No it is n

Rus_ich [418]

Answer:

<h3>No it is not in scientific notation</h3>

Step-by-step explanation:

The standard form of a scientific notation is expressed as:

A * 10^n where;

A is any number from between 1 and 10

Given the expression 33.4 × 10^ − 2

Comparing with the general formula, you will see that A = 33.2

Since the value of A does not fall between 1 and 10, hence the expression 33.4 × 10^-2 is not a scientific notation

Indicate whether the following analysis involves a statistical test. If it does involve a statistical test, state the population

Pie

Answer:

a

Yes it involves a statistical test

The population parameter(s) of interest is

The sample size is n = 100

The average reaction time of the right hands for the right-handed participants $\mu_R$

The average reaction time of the left hands for the left-handed participants $\mu_L$

The null hypothesis is $H_o : \mu_R = \mu_L$ ,

The alternative hypothesis is $H_a: \mu_R < \mu_L$

b

Yes it involves a statistical test

The population parameter(s) of interest is

The sample size is n = 100

The average reaction time of the right hands for the right-handed participants $\mu_R$

The average reaction time of the left hands for the left-handed participants $\mu_L$

The null hypothesis is $H_o : \mu_R = \mu_L$ ,

The alternative hypothesis is $H_a: \mu_R < \mu_L$

c

Yes it involves a statistical test

The population parameter(s) of interest is

The percentage of people in the community living in a mobile home is denoted with p

The sample size is n = 1000

The null hypothesis is $H_o : p =10\% = 0.01$ ,

The alternative hypothesis is $H_a: p >10\% = 0.01$

Step-by-step explanation:

Considering the first statement

Testing 100 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.

Yes, the analysis does involve a statistical test.

The null hypothesis is $H_o : \mu_R = \mu_L$ ,

The alternative hypothesis is $H_a: \mu_R < \mu_L$

Here $\mu_R$ is the average reaction time of the right hands for the right-handed participants

and $\mu_L$ is the average reaction time of the left hands for the left-handed participants

Considering third statement

Polling 1000 people in a large community to determine if there is evidence for the claim that the percentage of people in the community living in a mobile home is greater then 10%.

The percentage of people in the community living in a mobile home is denoted with p

The sample size is n = 1000

The null hypothesis is $H_o : p =10\% = 0.01$ ,

The alternative hypothesis is $H_a: p >10\% = 0.01$

Which of the function below could possibly have created this graph ?

lina2011 [118]

ANSWER

D.

$f(x) = - {x}^{4} + {x}^{3} + 3 {x}^{2}$

EXPLANATION

The given graph rises on the left and falls on the right.

This implies that the degree of the function is even.

Since the graph opens downward, the coefficient of the leading term must be negative.

The graph graph of the function also has 3 intercepts with one of them having an even multiplicity.

This means that the degree must be 4.

Therefore the last choice is correct.
