5.16 Identify hypotheses, Part II: Write the null and alternative hypotheses in words and then symbols for each of the following situations. (a) Since 2008, chain restaurants in California have been required to display calorie counts of each menu item. Prior to menus displaying calorie counts, the average calorie intake of diners at a restaurant was 1100 calories. After calorie counts started to be displayed on menus, a nutritionist collected data on the number of calories consumed at this restaurant from a random sample of diners. Do these data provide convincing evidence of a difference in the average calorie intake of a diners at this restaurant?

Answers

Answer 1

Answer:

H₀: µ = 1100 vs. Hₐ: µ ≠ 1100.

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.

Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.

The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.

It is also known as the research hypothesis and is denoted by Hₐ.

In this case the hypothesis can be defined as follows:

Null hypothesis:

H₀: The average calorie intake of a diner at this restaurant is 1100, i.e. µ = 1100.

Alternate hypothesis:

Hₐ: The average calorie intake of a diner at this restaurant is different from 1100, i.e. µ ≠ 1100.

Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in slope-intercept form (y = mx + b) with the values of m and b given as decimals, rounded to the nearest hundredth if necessary.

y = 2x ; (4, −4)

Answers

Answer:

y = -0.5x -2

Step-by-step explanation:

if two lines are perpendicular, their product equals -1

_________________________________________

let the equation of required line be

y = mx + b as given in the problem to be slope intercept form

m = slope

given line

y = 2x

it is also in y = mx + b , comparing this with y =2x

m = 2 and b =0

now

as product of two perpendicular lines = -1

m*2 = -1

thus

m = -1/2 = -0.5

thus,

slope of required line is -0.5

in y = mx + b

m = -0.5

thus,

y = -0.5x + b

given that this line passes through(4,-4)

putting y = -4 and x = 4 in this equation we can find value of b

-4 = -0.5*4 + b

-4 = -2 + b

=> -4 + 2 = b

thus, b = -2

Thus, slope intercept form of equation is y = -0.5x -2

To start we would resolve the absolute value of [tex]|-3|[/tex]. We know that absolute value is the distance from zero so it would be 3.

Our new equation is [tex]3+6/(4-1)*8[/tex]

Now we need to solve in the order of PEDMAS starting with parenthesis to get [tex]3+6/3*8[/tex]

Next in PEDMAS we have Division/Multiplication since we don't have any exponents. We do all the division and multiplication left to right so we would divide to get [tex]3+2*8[/tex]  and then multiply to get [tex]3+16[/tex].

Finally, we only have addition left over so our answer would be [tex]19[/tex]

Bobby rich dude has $120,000 in his account that pays him 5.5% compounded daily. What amount and how much interest will his money earn in 30-days?

Answers

Answer:

Interest: Amount Gained: $198,000

Final Balance: Amount After 30 days of Interest: $318,000

Step-by-step explanation:

Equation Used to Solve:

120,000 · 0.055 = 120,000 + (xy)

Let x represent 5.5% of 120,000

Let y represent the number of days.

Solving the equation:

120,000 · 0.055 = 6,600

x = 6,600; y = 30

120,000 + (6,600 · 30) = 120,000 + 198,000

120,000 + 198,000 = 318,000

Write an equation for the proportional relationship. Let X represent a length measured in meters and y represent the same length measured in centimeters. ​

Answers

Answer:

[tex]y=100x[/tex]

Step-by-step explanation:

Given that [tex]x[/tex] is the length measured in meters and

[tex]y[/tex] represents the same length measured in centimeters.

Let us first have a look at the relationship between meters and centimeters units of length.

1 unit of length in meters = 100 units of length in centimeters

Therefore, it can be said that:

2 units of length in meters = 200 units of length in centimeters

3 units of length in meters = 300 units of length in centimeters

4 units of length in meters = 400 units of length in centimeters

OR

[tex]x[/tex] units of length in meters = 100[tex]x[/tex] units of length in centimeters

It is given that [tex]y[/tex] is the length in centimeters.

Therefore, the proportional equation can be written as:

[tex]y=100x[/tex]

A.
The x-terms are the same, but the constant terms are different.


B.
The x-terms are different, and the constant terms are different.


C.
The x-terms are the same, and the constant terms are the same.


D.
The x-terms are different, but the constant terms are the same.

Answers

Answer:

C.  The x-terms are the same, and the constant terms are the same.

Step-by-step explanation:

Solve for x:

7 (x - 4) = 8 (x + 8)

Hint: | Write the linear polynomial on the left-hand side in standard form.

Expand out terms of the left hand side:

7 x - 28 = 8 (x + 8)

Hint: | Write the linear polynomial on the left-hand side in standard form.

Expand out terms of the right hand side:

7 x - 28 = 8 x + 64

Hint: | Move terms with x to the left-hand side.

Subtract 8 x from both sides:

(7 x - 8 x) - 28 = (8 x - 8 x) + 64

Hint: | Combine like terms in 7 x - 8 x.

7 x - 8 x = -x:

-x - 28 = (8 x - 8 x) + 64

Hint: | Look for the difference of two identical terms.

8 x - 8 x = 0:

-x - 28 = 64

Hint: | Isolate terms with x to the left-hand side.

Add 28 to both sides:

(28 - 28) - x = 28 + 64

Hint: | Look for the difference of two identical terms.

28 - 28 = 0:

-x = 64 + 28

Hint: | Evaluate 64 + 28.

64 + 28 = 92:

-x = 92

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of -x = 92 by -1:

(-x)/(-1) = -92

Hint: | Any nonzero number divided by itself is one.

(-1)/(-1) = 1:

Answer: x = -92
