For each menu item at a fast food restaurant, fat content (in grams) and number of calories were recorded. A scatterplot of these data is given:
sparta the restaurant decides to add six new high-calorie, low-fat pasta dishes to its menu.
What is a plausible value for the new correlation coefficient describing the relationship between fat and calories?
A plausible value for the correlation between fat content and calories is:__________.
A. +0.2.
B. –0.9.
C. +0.9.
D. –1.0

Answers

Answer:

Step-by-step explanation:

Hello!

Given the variables

Y-axis: X₁: Calories of a fast food menu.

X-axis: X₂: Fat of a fast food menu (grams)

The coefficient of correlation (r)

This coefficient shows ​​the degree of correlation between the variables and its range of values is between -1 and 1

If r = 0 then there is no linear correlation between X₁ and X₂ Graphically, the slope is zero

If r < 0 then there is a negative association between X₁ and X₂ (i.e. when one variable increases the other one decreases) In a graphic, the slope of the line is negative.

If r > 0 then there is a positive association between X₁ and X₂ (i.e. Both variables increase and decrease together)  

The closer to 1 or -1 the coefficient is, the stronger the association between variables. Using the absolute value of the correlation coefficients you can compare them, the greater the value, the stronger is the association between variables.

Looking at the scatter plot you can see that the number of calories grows with the fat content of the menu forming an approximately straight line, which means that there must be a strong positive correlation between these two variables. (using for example one of the options +0.90)

Meaning: To ↑x₁ corresponds ↑x₂ and to ↓x₁ corresponds ↓x₂

Now if the restaurant adds n=6 new menus with high calories (↑x₁) and low fat content (↓x₂) these new me nus won't follow a direct relationship, but an indirect one (negative correlation), so you'd expect the value of the correlation coefficient to drop (get closer to zero)

The coefficient won't get close to -1 since that would be a complete negative correlation (all foods having low fat and high calories), which could happen if the restaurant changed all menus.

Since they are only adding new ones, the new possible values for the coefficient of correlation could be A. +0.2 or D -0.1

Determine if the volume of the box is increasing, decreasing,or not changing at all, at that instant.

Answers

Answer:

the volume of the box is increasing

dV = +310,000 ft^3/s

Step-by-step explanation:

Volume of a rectangular box with side a,b and c can be expressed as;

V = abc

The change in volume dV can be expressed as;

dV = d(abc)/da + d(abc)/db + d(abc)/dc

dV = bc.da + ac.db + ab.dc ......1

Given:

a= 150 feet,

b= 80 feet, and

c= 50 feet

ais increasing at 100 feet/sec,bis decreasing 20 feet/sec, andcisincreasing at 5 feet/sec

da = +100 feet/s

db = -20 feet/s

dc = +5 feet/s

Substituting the values into the equation 1;

dV = (80×50×+100) + (150×50×-20) + (150×80×+5)

dV = +400000 - 150000 + 60000 ft^3/s

dV = +310,000 ft^3/s

Since dV is positive, the volume of the box is increasing at that instant.

C. what is the 95% confidence interval for the population variance (to 2 decimals)?
D. what is the 95% confidence interval for the population standard deviation (to 2 decimals)?

Answers

Answer:

A) sample mean = $1.36 million

B) standard deviation = $0.9189 million

C) variance confidence interval = ($0.40 million, $2.81 million)

D) standard deviation confidence interval = ($1.93 million , $0.79 million)

*since the sample size is very small, the confidence interval is not valid.

Step-by-step explanation:

samples:

$2.7 million$2.4 million$2.2 million$2 million$1.5 million$1.5 million$0.5 million$0.5 million$0.2 million$0.1 million

sample mean = $1.36 million

the standard deviation:

$2.7 million - $1.36 million = 1.34² = 1.7956$2.4 million - $1.36 million = 1.04² = 1.0816$2.2 million - $1.36 million = 0.84² = 0.7056$2 million - $1.36 million = 0.64² = 0.4096$1.5 million - $1.36 million = 0.14² = 0.0196$1.5 million - $1.36 million = 0.14² = 0.0196$0.5 million - $1.36 million = -0.86² = 0.7396$0.5 million - $1.36 million = -0.86² = 0.7396$0.2 million - $1.36 million = -1.16² = 1.3456$0.1 million - $1.36 million = -1.26² = 1.5876total $8.444 million / 10 = $0.8444 million

variance 0.8444

standard deviation = √0.8444 = 0.9189

in order to calculate the confidence interval for the population variance we are going to use a chi-square distribution with 2.5% on each tail ⇒ table values 2.7004 and 19.023 enclose 95% of the distribution.

[(n - 1) x variance] / 2.7004 = (9 x 0.8444) / 2.7004 = 2.81

[(n - 1) x variance] / 19.023 = (9 x 0.8444) / 19.023 = 0.40

95% confidence interval = mean +/- 1.96 standard deviations/√n:

$1.36 million + [(1.96 x $0.9189 million)/√10] = $1.36 million + $0.57 million = $1.93 million

$1.36 million - $0.57 million = $0.79 million

Explain your reasoning.

Answers

Answer:

It isn't plausible enough to at least say that the distribution is approximately normal because the percentiles given, when plotted on a number line aren't in any way symmetric about the mean as is required for a normal distribution.

Step-by-step explanation:

To investigate whether these values given for the distribution are plausible enough to at least say that the distribution is approximately normal, we will plot the given percentiles on a number line and indicate the median and mean too on that number line.

The spread of the other percentiles about the mean especially and to an extent, the median will show if the distribution is symmetric/ almost symmetric about the mean and the median.

The plot of these percentiles and the mean is presented in the attached image to this answer. The percentiles are indicated with deep dots and the mean is shown with a light square.

The plot shows that the distribution isn't symmetric about the mean and the median. The distribution appears to be skewed to the right.

Hence, it isn't plausible enough to at least say that the distribution is approximately normal because the percentiles given, when plotted on a number line aren't in any way symmetric about the mean as is required for a normal distribution.

The value of a house is increasing by $1500 per year. If it is worth $120,000 today, what will it be worth in three
years?​

Answers

Answer:

The growth is linear.

It will be worth $124,500 in three years.

Step-by-step explanation:

The value of a house is increasing by $1500 per year.

Fixed increase, that is, each year the value increases the same. So the growth is linear.

Value after t years:

The equation has the following format:

[tex]V(t) = V(0) + a*t[/tex]

In which V(0) is the current value and a is the yearly increase.

The value of a house is increasing by $1500 per year. It is worth $120,000 today.

Then [tex]V(0) = 120000, a = 1500[/tex]

So

[tex]V(t) = V(0) + a*t[/tex]

[tex]V(t) = 120000 + 1500*t[/tex]

What will it be worth in three years?​

This is V(3).

[tex]V(t) = 120000 + 1500*t[/tex]

[tex]V(3) = 120000 + 1500*3[/tex]

[tex]V(3) = 124500[/tex]

It will be worth $124,500 in three years.

The growth is linear. The worth of the house after 3 years from now will be $124500.

Given information:

The value of a house is increasing by $1500 per year.

It is worth $120000 today.

The value of the house increases at a fixed rate of $1500 per year. So, it is a linear growth function.

Let the worth of the house after t years be V. The given situation can be written in equation form as,

[tex]V=V_0+rt\\V=120000+1500t[/tex]

Above equation represents the worth of house after t years.

So, the worth of the house after 3 years will be calculated as,

[tex]V=120000+1500t\\V(3)=120000+1500\times 3\\V(3)=120000+4500\\V(3)=124500[/tex]

Therefore, the worth of the house after 3 years from now will be $124500.

Answers

Answer:

x=2

Step-by-step explanation:

We know that

f(x)=2(x+10)

and

f(x)=24

Therefore, by substitution, we can set the 2 expressions equal to each other.

2(x+10)=24

Now, we need to solve for x. Perform the opposite of what is being done to the equation, and remember to perform everything to both sides.

2 and x+10 are being multiplied. The opposite of multiplication is division, so divide both sides by 2.

2(x+10)/2=24/2

x+10=24/2

x+10=12

10 is being added to x. The opposite of addition is subtraction. Subtract 10 from both sides.

x+10-10=12-10

x=12-20

Perpendicular Lines

Linear equations are typically organized in slope-intercept form:

[tex]y=mx+b[/tex]

m = slopeb = y-intercept

Perpendicular lines have slopes that are negative reciprocals.

Example: 2 and -1/2Example: 3/4 and -4/3

Solution

We're given:

Perpendicular to [tex]4x-5y=-10[/tex]Passes through (6,3)

1) Determine the slope

Let's first rearrange this equation into slope-intercept form:

[tex]4x-5y=-10\\-5y=-4x-10\\\\y=\dfrac{4}{5}x+2[/tex]

Notice how [tex]\dfrac{4}{5}[/tex] is in the place of m in y = mx + b. This is the slope of the give line.

Since perpendicular lines are negative reciprocals, we know the slope of the other line is [tex]-\dfrac{5}{4}[/tex]. Plug this into y = mx + b:

[tex]y=-\dfrac{5}{4}x+b[/tex]

2) Determine the y-intercept

We're also given that the line passes through (6,3). Plug this point into our equation and solve for b:

[tex]y=-\dfrac{5}{4}x+b\\\\3=-\dfrac{5}{4}(6)+b\\\\b=3+\dfrac{5}{4}(6)\\\\b=\dfrac{21}{2}[/tex]

Plug this back into our original equation:

a caj register contains $10 and $50 with a total value of$1080. If there are 28 bills total, then how many if each does the register contain?​

Answers

Answer:

Step-by-step explanation:

We can solve by means of a system of equations:

let x register $ 10

let y register $ 50

Now, we have:

10 * x + 50 * y = 1080

x + y = 28 => <x = 28 - y

replacing:

10 * (28 - y) + 50 * y = 1080

280 - 10 * y + 50 * y = 1080

40 * y = 1080 - 280

y = 800/40

y = 20

now for x:

x = 28 - 20

x = 8

which means that in total there are 8 register of $ 10 and 20 register of $ 50

Find the focus and directrix of the parabola y = {(x + 2)2 – 3.

Answers

Answer:

focus: (-2, -2.75)directrix: y = -3.25

Step-by-step explanation:

For focus-to-vertex distance "p", the equation of a parabola with vertex (h, k) can be written as ...

  y = 1/(4p)(x -h)^2 +k

Comparing this to your equation, we see that ...

  1/(4p) = 1

  h = -2

  k = -3

Solving for p, we find ...

  1/(4p) = 1

  1/4 = p . . . . . multiply by p

The parabola opens upward, so this means the focus is 1/4 unit above the vertex, and the directrix is 1/4 unit below the vertex.

focus: (-2, -2.75)directrix: y = -3.25

Adrian is training for a 5K race. She
ran 5.5 miles the first week, 7.25
miles the second week and 10 miles
the third week. On the average, how
many miles did she run per week?
Round to the nearest hundredth.
PLZ HELP PLZ!!!!!

Answers

To get this we divide the total miles she ran for the weeks by the no of weeks she ran.

Total miles =5.5 +7.25+10= 22.25 miles altogether.

no of weeks =3.

Average miles = 22.75 /3=7.583333≅7.58(nearest hundredth)

In a village
The number of houses and the number of flats are in the ratio 9:5
The number of flats and the number of bungalows are in the ratio 10:3
There are 30 bungalows in the village.
How many houses are there in the village?
Note: please make sure your final answer clear by writing ... houses

Answers

there will be 180 houses.

The number of houses are 180, and the number of flats are 100.

It is given that the number of houses and the number of flats ratio is 9:5 the number of flats and the number of bungalows ratio is 10:3.

It is required to find the number of houses in the village if the number of bungalows is 30.

What is a fraction?

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The ratio of the number of houses and the number of flats:

= 9:5   and

The ratio of the number of flats and the number of bungalows :

=10:3

It means we can write the ratio of the number of houses and the number of flats = 18:10

And the ratio of the number of:

Houses : Flats : Bungalows = 18:10:3

But the number of bungalows are 30.

Then the ratios are:

180:100:30

Thus, the number of houses are 180, and the number of flats are 100.

QUESTION 23 What does a BER of 10-5 mean? a. there will be no errors during transmission since the BER is so low b. does not mean anything unless associated with a transmission data rate (bit rate) c. there is a probability of one error for every 100,000 bits transmitted d. None of the above

Answers

Answer:

c. there is a probability of one error for every 100,000 bits transmitted

Step-by-step explanation:

What does a BER of 10-5 mean?

a. there will be no errors during transmission since the BER is so low b. does not mean anything unless associated with a transmission data rate (bit rate) c. there is a probability of one error for every 100,000 bits transmitted d. None of the above

BER is an abbreviation for bit error rate.

BER is the percentage of bits with errors divided by the total number of bits that have been transmitted, received or processed over a given time period.

The rate is typically expressed as 10 to the negative power.

BER is the digital equivalent to signal-to-noise ratio in an analog system.

In this case [tex]10^{-5}[/tex]  is the same as writing [tex]1 \times10^{-5}[/tex]  which means there is a probability of 1 error for every 100,000 bits transmitted.
