Actually Welcome to the Concept of the indices,

After applying the log rules we get the equation as,

===> 3-x = 1/2

===> x = 5/2

Answer:

f(x) = 4x² + 48x + 149

Step-by-step explanation:

Given

f(x) = 4(x + 6)² + 5 ← expand the factor using FOIL

     = 4(x² + 12x + 36) + 5 ← distribute parenthesis by 4

     = 4x² + 48x + 144 + 5 ← collect like terms

     = 4x² + 48x + 149 ← in standard form

Answer:

C. 8 miles per hour

Step-by-step explanation:

It takes Diego [tex]\frac{1}{8}[/tex] of an hour to complete the lap = [tex]\frac{1}{8}[/tex] x 1 hour = [tex]\frac{1}{8}[/tex] hour

Distance of the track = 1 mile long

The speed of an object expresses the ratio of distance moved to time taken to cover the distance.

i.e speed = [tex]\frac{distance}{time taken}[/tex]

           = [tex]\frac{1}{\frac{1}{8} }[/tex]

           = 8

Speed = 8 mile per hour

Therefore, Diego's bike has a speed of 8 miles per hour.

Complete question :

Liz's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and regression line below show the relationship between how many hours students spent studying and their score on the test.

The fitted line has a slope of 15.

What is the best interpretation of this slope?

Answer:

C.)

The model predicts that the score will increase 15 points for each additional hour of study time.

Step-by-step explanation:

The slope of a regression line represents the rate of change :

From the formula :

Rise / Run = (y2 - y1) / (x2 - x1).

The slope is a Coefficient which shows how much the dependent variable changes per unit change in the independent variable.

Hence, for a slope value of +15, which is positive, meaning an increase ; then the score obtained will increase by 15 per additional unit increase in hour of study.

Answer:

Row 2 Column 2: 1/25

Row 2 Column 3: 0.04

Row 3 Column 1: 75%

Row 3 Column 3: 0.75

Row 4 Column 1: 80%

Row 4 Column 2: 4/5

Answer:

4 as a fraction is 1/25 as a decimal 0.04

3/4 as a percentage is 75% as a decimal 0.75

0.8 as a fraction 4/5 and as a percentage is 80%

Answer:

Add all of the numbers then put a Y at the end.

Step-by-step explanation:

its just combining like terms, if their all Y. its jist adding with a letter at the end

Step-by-step explanation:

x= (70+83+90)/3= 81

85=(89+75+y)/3

255=89+75+y

y=91

92=(86+a+a)/3

276=86+2a

2a=190

a=95

93=(b+b+b)/3

279=3b

b=93

Answer:

(x + 20)(x + 11)

Step-by-step explanation:

x(x + 20) + 11(x + 20) =

Factor out the common factor of x + 20.

= (x + 20)(x + 11)

The binomials make it look complicated, but this is simpler than you think.

Look at this simpler, but similar, example.

Factor xy + 4y

xy + 4y =

You see clearly that y is a common factor, so you factor out y, and you get

= y(x + 4)

In your problem, you have

x(x + 20) + 11(x + 20) =

where (x + 20) is the common factor.

You factor out the common factor, (x + 20). What is left? x + 11 as a factor, so you get

(x + 20)(x + 11)

Answer:

Population is the total number of people that fall into the description of those that the research concerns.

In this case, Population is: Everyone who signed a card saying that they intend to quit smoking.

Sample. This is a subset of the population that the research is based on.

Sample = 1,000 people surveyed.

Parameter and Statistic are both descriptive measures but parameter is for the population and statistic is for the sample.

Parameter = Percentage of total population who have not smoked in 6 months.

Statistic = 21% of sample who have not smoked in 3 months.

Answer:

x = 5 (please read the step by step explanation)

Step-by-step explanation:

So, I'm just going to solve for x because the instructions aren't too clear. I believe there is supposed to be an image attached to it, but seeing as I don't have that, I'll just solve for x and you can plug in with the values.

15x = 12x + 15

Same to both sides:

3x = 15

Isolate x:

x = 5

Just plug in those values and you'll be good to go! Have a good day!
