You try to explain the number of IBM shares traded in the stock market per day in 2005. As an independent variable you choose the closing price of the share. This is an example of A. invalid inference due to a small sample size. B. sample selection bias since you should analyze more than one stock. C. simultaneous causality.

Answers

Answer 1

Answer:

This is an example of

C. simultaneous causality.

Step-by-step explanation:

Simultaneous causality eliminates the conclusion that is often taken for granted to the effect that one variable is a response variable while the other is an explanatory variable because the two variables, the price and the number of shares, influence each other at the same time.  When more shares are traded than demanded in the stock market in any day, the price tends to go down, and vice versa.

What is the answer?

Answers

Answer:

A

Step-by-step explanation:

2+3=5, 5+3=8, 8+3=11. 2x3=6, 5x3=15, 8x3=24, 11x3=33

Answer:

A

Step-by-step explanation:

Proportional is where everything will match

so we have 2x3=6 5x3=15 8x3=24 11x3=33

This works because it continues the same line of multiplication (x3).

But like B,  you start with 4,4=16 which works, but now you have 5x4=21, which will not work because 5x4 will never equal 21

Two sets of three consecutive integers have a property that the product of the larger two is
one less than 7 times the smallest. Set up and solve an equation that can be sue to find both
sets of integers. What are those sets of integers?

Answers

Answer:

{1, 2, 3},  {3, 4, 5}

Step-by-step explanation:

Write expressions for three consecutive integers:  n, n + 1, n + 2.

Set up an equation for the verbal description: the product (mulitplication) of the two larger integers (the last two) is one less than 7 times the smallest (the first one).

(n + 1)(n + 2) = 7n - 1

Multiply (FOIL) the left side.

n^2 + 3n + 2 = 7n - 1

Subtract 7n and subtract 1 to make the right side 0.

n^2 - 4n + 3 = 0

Factor.

(n - 1)(n - 3) = 0

Set the two factors equal to 0

n - 1 = 0,  n - 3 = 0

Solve for n.

n = 1,  n = 3

One set of integers begins with 1, so it's {1, 2, 3}.

The other set begins with 3, so it's {3, 4, 5}

∠1 ≅ ∠3 [Vertically opposite angles]

∠1 ≅ ∠5 [Corresponding angles]

∠1 ≅ ∠7 [Alternate exterior angles]

Step-by-step explanation:

The probability that Trey's card will be a heart or a black-suited card is

3/4

What is probability?

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Deck of cards contains,

spade=13, heart=13, diamonds=13, clubs= 13

In which clubs and spades are black and hearts and diamonds are red.

Total (Black suited card with a heart) =26+13= 39

P( heart or a black-suited card)=39/52

                                                    =3/4.

Hence, probability of heart or a black-suited card is 3/4

sec(θ) =

cot(θ) =

Answers

sin(theta)=-15/17
cos(theta)=8/17
tan(theta)=-15/8
csc(theta)=-17/15
sec(theta)=17/8
cot(theta)=-8/15
Hope this helps

Answers:

sin(θ) =  -15/17 cos(θ) = 8/17 tan(θ) =  -15/8 csc(θ) = -17/15 sec(θ) =  17/8 cot(θ) = -8/15

=======================================================

Explanation:

Refer to the diagram below. The point (8,-15) is in quadrant 4, which is the southeast quadrant. A right triangle forms where the hypotenuse goes from the origin to the terminal point in question. After applying the pythagorean theorem, the hypotenuse is 17 units long.

Opposite the reference angle θ, greek letter theta, the side is -15. Usually negative lengths are not allowed and don't make any sense; however, I'm making this negative to ensure that sin(θ) ends up negative. This will help with other trig ratios as well.

So,

sin(angle) = opposite/hypotenuse

sin(θ) = -15/17

-----------------

The cosine ratio will involve the adjacent and hypotenuse

cos(angle) = adjacent/hypotenuse

cos(θ) = 8/17

------------------

Tangent is opposite over adjacent

tan(angle) = opposite/adjacent

tan(θ) = -15/8

------------------

The functions csc(θ), sec(θ), and cot(θ) are the functions cosecant, secant, and cotangent in that order.

They represent the reciprocal of sine, cosine, and tangent in that order as well.

Eg: sec(θ) is the reciprocal of cos(θ)

This means,

csc(θ) = -17/15 which is the flip of sin(θ) = -15/17sec(θ) = 17/8 which is the flip of cos(θ) = 8/17cot(θ) = -8/15 which is the flip of tan(θ) = -15/8

As an alternative, you could also say

csc(θ) = hypotenuse/opposite = 17/(-15) = -17/15sec(θ) = hypotenuse/adjacent = 17/8cot(θ) = adjacent/opposite = -15/8

------------------------

Here's a list of formulas that you can write down on a reference sheet

sin(θ) =  y/h cos(θ) =  x/h tan(θ) = y/x csc(θ) = h/y sec(θ) = h/x cot(θ) = x/y

where h is the hypotenuse and h = sqrt(x^2+y^2). Notice that something like tan = y/x is the reciprocal of cot = x/y. The x and y refers to the coordinates of the terminal point given to you. Make sure to reduce all fractions as much as possible. In our case, none of the fractions can be reduced any further.

Jason drove 8 4/5 miles to a subway station. He then 15 /6 miles by taxi to attend a meeting. How many total miles did he travel?

Answers

Answer:

Option A: (23 + 29/30) miles

Step-by-step explanation:

Here we just need to add two mixed numbers.

(8 + 4/5) miles and (15 + 1/6) miles.

To add these, we just separate between the whole part and the fraction part:

(8 + 4/5) miles + (15 + 1/6) miles

= (8 + 4/5 + 15 + 1/6) miles

= (8 + 15 + 4/5 + 1/6) miles

= (23 + 4/5 + 1/6) miles

Now we need to find a common multiple between 6 and 5.

So, only analyzing the fraction part of the sum, we can rewrite:

4/5 + 1/6

= 4/5*(6/6) + 1/6*(5/5)

(notice that we are multiplying both numbers by one, so we do not change the expression's value)

= (4*6)/(5*6) + (1*5)/(6*5)

= 24/30 + 5/30

So now both fractions have the same denominator.

Then, replacing that in the sum equation we get:

(23 + 4/5 + 1/6) miles =  (23 + 24/30 + 5/30) miles

= (23 + 29/30) miles

Then the correct option is option A.

Step-by-step explanation:

Since we have the Hypotenuse given and we need to find the value of the adjacent side of the given angle we would use the Cosine Ratio;

Cos(46) = [tex]\frac{x}{13}[/tex]

To solve for "x" we would first have to isolate the "x" all to itself.

To isolate the variable, simply multiply 13 to the both sides of "="

=> Cos(46) * 13 = x

=> 9.03 = x

So you can write the answer in either of the 2 ways mentioned above, if you need a fully simplified answer the second answer would be a better fit. If u just need the Equation the 1st equation would be the better fit.
