Matthew rode his bike 5/8 mile in 1/4 hour. What is the unit rate in miles per hour?

Answers

Answer:

The unit rate in miles per hour is 2.5 mph.

Step-by-step explanation:

Since Matthew rode his bicycle for 5/8 of a mile in a quarter of an hour, to determine the speed at which he was traveling we must perform the following calculation:

1/4 x 4 = 1 hour

5/8 x 4 = miles that would have been covered in one hour

20/8 of a mile would have been covered in one hour

20/8 = 2.5

2.5 miles would have been covered in an hour, with which his speed was 2.5 mph.

Some people think that the behavior of the stock market in January predicts its behavior for the rest of the year. Let the explanatory variable be the percent change in a stock market index in January. Let the response variable be the percent change in the stock market index for the entire year. You have a data set with 50 cases (where each case is a calendar year). Based on this data, you have the following statistics: mean of the x-variable: 2.75% standard devation of the x-variable: 4.48% mean of the y-variable: 8.17% standard devation of the y-variable: 22.31% correlation between the two variables: 0.655 Suppose that the mean change in January is 10.81%. What is the predicted value of the change in the stock market index for the year

Answers

Answer:

1.95

Step-by-step explanation:

Formula for slope is = γ Sy/Sx

γ = Correlation, Sy = S.D. of Y value, Sx= S.D. of X value

Sy = 8.17% = 0.0817

Sx = 2.75% = 0.0275

γ = 0.655

Slope = 0.655 *(0.0817/0.0275)

Slope = 1.94595

Slope = 1.94595

Slope = 1.95

Therefore, the slope of the regression line is 1.95

Suppose f(x) = 2(x + 1)2 and f(g(x)) = 2(2x + 4)2. What is g(x)?

Answers

Answer:

C

Step-by-step explanation:

Did the test and got it right.

The function g(x) = 2x + 3 if  f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)² option (C) is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Suppose f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)². What is g(x)?

A.g(x) = x + 3

B.g(x) = x + 4

C.g(x) = 2x + 3

D.g(x) = 2x + 4

We have:

f(x) = 2(x + 1)²

Let take g(x) = 2x + 3

Find f(g(x))

f(2x + 3) = 2[(2x+3) + 1]²

= 2(2x + 4)² = f(g(x))

Thus, the function g(x) = 2x + 3 if  f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)² option (C) is correct.

Answer & Step-by-step explanation:

On the left:

There are 4 triangles that indicate -x, so this is -4

There are 3 circles that indicate -1, so these are -3.

Insert as an expression:

[tex]-4x-3[/tex]

On the right:

There are 2 triangles that indicate -x, so this is -2x.

There are 2 circles that indicate -1, so these are -2.

Insert as an expression:

[tex]-2x-2[/tex]

Combine both expressions into an equation:

[tex]-4x-3=-2x-2[/tex]

Solve for x. Add 3 to both sides:

[tex]-4x-3+3=-2x-2+3\\\\-4x=-2x+1[/tex]

Add 2x to both sides:

[tex]-4x+2x=-2x+2x+1\\\\-2x=1[/tex]

What is m∠PTQ? a. 12 b. 40 c. 50 d. 140

HELP!!!

Answers

Answer:

B. 40°

Step-by-step explanation:

m<PTQ = (x + 28)°

m<RTS = (2x + 16)°

Angle PTQ and angle RTS are vertically opposite angles, therefore, m<PTQ = m<RTS

[tex] x + 28 = 2x + 16 [/tex]

Solve to find the value of x

[tex] x + 28 - 2x = 2x + 16 - 2x [/tex] (subtracting 2x from each side)

[tex] -x + 28 = 16 [/tex]

[tex] -x + 28 - 28 = 16 - 28 [/tex] (subtracting 28 from each side)

[tex] -x = -12 [/tex]

[tex] x = 12 [/tex] (dividing each side by -1)

Find angle PTQ:

m<PTQ = (x + 28)°

Plug in the value of x

m<PTQ = 12 + 28 = 40°

Step-by-step explanation:

An experimental unit refers to the subject or factor under investigation. The subject or factor is subjected to different treatments in the course of the study. In the case of the experimental situation described above, the pine tree seedlings are the experimental units that actually received the treatments.

The treatments included being subjected to full or reduced light in the greenhouse. The response of the seedlings to these treatments would determine the outcome of the study.

Huntington\'s disease is an inherited autosomal dominant disorder that can affect both men and women. Imagine a couple has had seven children, and later in life, the husband develops Huntington\'s disease. He is tested and it is discovered he is heterozygous for the disease allele, Hh. The wife is also genetically tested for the Huntington\'s disease allele, and her test results show she is unaffected, hh. A.) What is the percent probability that the first child of this couple will have Huntington\'s disease? B.) What is the probability that any six of the seven children will have Huntington\'s disease?

Answers

Answer:

a) probability that the first child of this couple will have Huntington's disease is 1/2 = 50%

b) probability that any six of the seven children will have Huntington's disease is 0.05468  ( 5.468% )

Step-by-step explanation:

a)

Given that;

Hh ( diseased father) and hh (normal)

         H   h

h Hh hh

h Hh hh

therefore Hh ⇒ 2 and hh ⇒ 2

so here we can see that chances of getting Huntington's disease is 1 : 1

so probability that the first child of this couple will have Huntington's disease is 1/2 = 50%

b)

probability that 6 out of the 7 children will have Huntington's disease;

we use the expression

<P> = (n! / (S! × t!)) × p^S × q^t

where n! is total number of children factorial

S! is diseased number of children factorial

t! is healthy number of children factorial

p is probability of diseased children

q is probability of healthy children

so we substitute

<P> =  (7! / (6! × 1!)) × 1/2^6 × 1/2^1

= (7 × 6! / (6! × 1!)) × 1/2⁶ × 1/2

= 7 × 1/64 × 1/2

= 0.05468

probability that any six of the seven children will have Huntington's disease is 0.05468  ( 5.468% )

     

The Huntington's disease.

As per the question, the disease is a rare inherited disease that is caused by the breakdown of the nerve cells of the brain. The disease has a broad impact on functional abilities and usually results in movement, thinking, and other disorders.

Thus the answer is the chance of the disease to a child is about 50% as it starts at age of 30 to 40. The chances of six children are 5.4%.

The disease is an inherited aspect of the body genes and the disorder s created is due to the diseases allele is heterozygous The results shows that the chances of the first child to have this disease will be 1/2 that is 50% and the chances if any six people out of seven that have this disease is about 5.46%

A make-your-own ice pop kit says to pour 4 fluid ounces of juice into each bag. How many ice pop bags can you fill with 1 quart of juice?

Answers

Answer: 8 bags.

Step-by-step explanation:

It is given that, a make-your-own ice pop kit says to pour 4 fluid ounces of juice into each bag.

We need to find the number of ice pop bags we can fill with 1 quart of juice.

We know that,

1 quart = 32 ounces

We have  32 ounces of juice and each bag contains 4 fluid ounces.

[tex]\text{Number of ice pop bags}=\dfrac{\text{Total juice}}{\text{Juice contained in each bag}}[/tex]

[tex]\text{Number of ice pop bags}=\dfrac{32}{4}[/tex]

[tex]\text{Number of ice pop bags}=8[/tex]

Therefore, 8 ice pop bags we can  fill with 1 quart of juice.

Which of the following variables are categorical?
I. Driver ID
II. Age
III. Car
IV. Gender

Answers

Answer: IV. Gender

Step-by-step explanation:

A categorical variable is a variable that has two or more categories.

Driver ID consists of numbers and alphabet and it has no category.

Age is expressed in numbers , it cannot be categorical.

Car has many types but not category.

Gender has mainly 2 categories as male and female (some times 3 if we include transgender)

So, Gender is a categorical variable.

So correct option is IV. Gender

Brayden signed up for a streaming music service that costs $11 per month. The service allows Brayden to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $1 per song. How much total money would Brayden have to pay in a month in which he downloaded 35 songs? How much would he have to pay if he downloaded s songs?

Answers

s = # of songs

y = total amount of money

$11 + $1(35) = y

Simplify the right side

$11 + $35 = y

Combine like terms

$46 = y

If he downloaded 35 songs, he would have ti pay $46

If he downloaded s amount of songs, he would have to pay $11 + $1s = y

Answers

Answer:

Purchases= $39,800

Step-by-step explanation:

Giving the following information:

Beginning Supplies= 1,400

Ending Supply balance= 4,500

COGS= 36,700

To calculate the purchases, we need to use the following formula:

Purchases= COGS + desired ending inventory - beginning inventory

Purchases= 36,700 + 4,500 - 1,400

Purchases= $39,800
