A survey shows that 2/3 of all homeowners have a pet. Of those, 3/4 have either a dog or a cat. Of the homeowners, what fraction has either a dog or a cat ?

Answers

Answer:

Of the homeowners, half have either a dog or a cat.

Step-by-step explanation:

Since 2/3 of all homeowners have a pet, and 3/4 of those have dogs or cats, we simply need to multiply 2/3 and 3/4 to see what fraction of all homeowners have a dog or a cat.

2/3 x 3/4 = 6/12

6/12 = 1/2

We can double check this. If there are 60 homeowners, and 2/3 have a pet, that would mean that 40 of those homeowners have a pet.

If 3/4 of the 40 homeowners have either a dog or a cat, that would equate to 30 homeowners having either a dog or a cat.

Since 30 is half of 60, this would mean that 1/2 of the 60 homeowners have a dog or cat!

8-(-4f-3)≤ -f-8+2f
solve for f

Answers

Answer:

f ≤ - [tex]\frac{19}{3}[/tex]

Step-by-step explanation:

8 - (- 4f - 3 ) ≤ - f - 8 + 2f ← distribute parenthesis on left side by - 1

8 + 4f + 3 ≤ f - 8

4f + 11 ≤ f - 8 ( subtract f from both sides )

3f + 11 = - 8 ( subtract 11 from both sides )

3f ≤ - 19 ( divide both sides by 3 )

f ≤ - [tex]\frac{19}{3}[/tex]

ANSWER ASAP A basketball team played six games. In those​ games, the team won by 8 ​points, lost by 8​, won by 7​, won by 10​, lost by 2​, and won by 9. What was the mean difference in game scores over the six​ games?

Answers

The average difference or mean in game scores across six games is 5.67

Mean

The mean is the average of a data set. The mode is the most common number in a data set. The median is the middle of the set of numbers. The mean is the average or the most common value in a collection of numbers. the mean is one of the measures of b, apart from the mode and median. Mean is nothing but the average of the given set of a data.

To solve this problem, we have to write the wins and loss separate and then find the mean.

Wins = 8 points, 7 points, 20 points, 9 points

Loss = 8 points, 2 points

The sum of win points = 8 + 7 + 20 + 9 = 44 points

The sum of lost points = 8 + 2 = 10 points

The mean difference = (win - loss)/ total number of games

The mean difference = ( 44 - 10) / 6

The mean difference = 34 / 6 =5.67

The mean difference in the game scores over six games is 5.67 points

x + 25/-8 = -6 Solve for x.
Simplify your answer as much as possible.

Answers

Step-by-step explanation:

if there is nothing missing, we have

x + 25/-8 = -6

in order to compare or add or subtract fractions, we need to bring them all to the same denominator (bottom part).

remember, integer numbers are fractions too. like here

-6 = -6/1

25/-8 = -25/8

so, how can we bring -6/1 to .../8 ?

by multiplying 1 by 8.

but we cannot multiply only the denominator by 8. otherwise we would suddenly have

-6/8

and is -6/8 = -6/1 ? no, certainly not.

to keep the original value of the fraction we have to do the same multiplication also with the numerator (top part).

so, we actually do

-6/1 × 8/8 = -48/8

with this little trick we have now .../8 to operate with, and our transformed fraction has still the same value

-6/1 = -48/8 indeed.

so, we have

x + -25/8 = -48/8

x - 25/8 = -48/8

x = -48/8 + 25/8 = -23/8

The estimate number of cars that can be produced (C in thousands) at a manufacturing plant over the course of time (x in years) can be modeled by the polynomial function

Answers

The average rate of change between year 1 and year 10 is given as follows:

4.3 thousand cars a year.

How to obtain the average rate of change of a function?

The average rate of change of a function is obtained by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

In this problem, the function is presented as follows:

C(x) = 0.15x³ - 3.28x² + 23.75x - 2.1.

The interval is:

[1,10], hence a = 1, b = 10.

At x = 1, the numeric value is found replacing each instance of x by 1, hence:

C(1) = 0.15(1)³ - 3.28(1)² + 23.75(1) - 2.1 = 18.52 thousand cars.

At x = 10, the numeric value is found replacing each instance of x by 10, hence:

C(10) = 0.15(10)³ - 3.28(10)² + 23.75(10) - 2.1 = 57.4 thousand cars.

Then the average rate of change is obtained as follows:

r = (57.4 - 18.52)/(10 - 1) = 4.3 thousand cars a year.

Write a linear function f with the values f(0) = −5 and f(1) =−3.
A function is f(x)=¯

Answers

Answer:

     [tex]y=2x-5[/tex]

Step-by-step explanation:

We want to find a linear function [tex]f(x)[/tex] with the values

[tex]f(0)=-5\\f(1)=-3[/tex]

These mean that when x is 0, y is -5, and when x is 1, y is -3.

This means that we want to find the equation of a line that goes through the ordered pairs below:

[tex](0,-5)\\(1,-3)\\[/tex]

Let's find the slope between the two ordered pairs. The slope is the rise over the run. The rise is the change in y-values.

[tex]-3--5=-3+5=2[/tex]

The change in y-values is 2.

The run is the change in x values.

[tex]1-0=1[/tex]

The change in x-values is 1.

The slope is the rise divided by the run, so:

[tex]slope=\frac{2}{1}=2[/tex]

Now that we know the slope, let's find the y-intercept! This is when x equals 0. Luckily, that number is already given! We know that when x equals 0, y equals -5!

[tex]intercept=-5[/tex]

Now that we have the slope and intercept, we can plug these numbers into slope-intercept form!

Answers

Answer:

2/5 is greater than 3/8, so 25 2/5 is greater

Step-by-step explanation:

Find the least common denominator or LCM of the two denominators:

LCM of 5 and 8 is 40

Next, find the equivalent fraction of both fractional numbers with denominator 40

For the 1st fraction, since 5 × 8 = 40,

2/5

=

2 × 8

5 × 8

=

16/40

Likewise, for the 2nd fraction, since 8 × 5 = 40,

3/8

=

3 × 5

8 × 5

=

15/40

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

16/40 > 15/ 40 or 2/5 > 3/8

[tex]3x_{11} - 8x_{21}[/tex] = 32 ____(a)

[tex]x_{11} + x_{21}[/tex] = 7 ______(b)

From (b) we get,

Substitute (3) in (a)

Now,

3 (7 - [tex]x_{21}[/tex]) - 8[tex]x_{21}[/tex] = 32

21 - 3[tex]x_{21}[/tex] - 8[tex]x{21}[/tex] = 32

Answer:

Step-by-step explanation:

h(x) = -2x - 5

Let x = 9

h(9) = -2*9 - 5

h(9) = -18 - 5

        = -23

Answer:

h(9) = -23

Step-by-step explanation:

Given explanation,

→ h(x) = -2x - 5

Then the value when h(x) = 9 is,

→ h(x) = -2x - 5

→ h(9) = -2(9) - 5

→ h(9) = -18 - 5

→ h(9) = -23

Hence, the value of h(9) is -23.

There are two zeros so we need two numbers.

Then there are two numbers before the decimal.

We can write 06 before the decimal.

.06

6 hundredths can be written as 0.06 as a decimal.

What is fraction?

All fractions consist of a numerator and a denominator, separated by horizontal bars called fraction bars.

The denominator indicates the number of parts into which the whole is divided. Placed at the bottom of the break below the break bar. The

counter indicates how many sections of the fraction are displayed or selected. Placed at the top of the break above the break bar.

A common fraction is a numeral which represents a rational number. That same number can also be represented as a decimal, a percent, or with a negative exponent.

6 hundredths means that when you divide "something" into a hundred equal parts, 6 hundredths are six of the newly divided parts.

When you divide 6 by hundreds, you get 6 hundredths as a decimal, which is 0.06.

Therefore, 6 hundredths can be written as 0.06 as a decimal.

If the overhead was 20% of the cost of each towel. The selling price of each towel is 5.88.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

Suppose the selling price of a towel is x, according to the given condition,

5 = x - 15% of x

5=x-0.15x

5=0.85 x

x=5/0.85
