Find the values of x and y.

timurjin [86]

Answer:

x= 38

y= 71

Step-by-step explanation:

The triangle shown in the figure is an isosceles triangle, a triangle having two sides equal.

The two sides marked with a "dash" are said to be equal.

If we label off the triangle as ABC with AD being the extended length (containing 108°).

We'll get,

AB = AC

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

*Property*

"If two sides of a triangle are equal their corresponding base angles are equal too."

=> ∠BAC = ∠BCA . . . . (¡)

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

From the figure, ∠BCA is equal to y.

*Property*

"Two angles on a straight line sum up to 180°"

∠BAC can be found out by subtracting 109° from the straight angle (180°).

=> ∠BAC = 180 - 109

=> ∠BAC = 71°

Substituting these values in eqn. (¡):

71 = y

Hence, the value of y is 71°

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

*Property*

"The exterior angle(angle on the extended side) of a triangle is equal to the sum of it's interior opposite angles."

Here,

Interior angles = x and y (= 71)
Exterior Angle = 109°

=> 109 = x + 71

=> 109 - 71 = x

=> x = 38°

Hence, the value of x is 38°.

How is a scatter plot that shows no correlation different from a scatter plot that shows a negative correlation?

Crank

A scatter plot that has no correlation shows points that a trend line cannot be drawn through and that their is no correlation between the X values and Y values. A scatter plot with a negative correlation has a correlation between the X and y values where as X increases why decreases. A trend line with a negative slope can also be drawn on a negative correlation scatter plot.

Hope that helped or even made sense

HELP QUICK I ONLY HAVE 1 CHANCE

Otrada [13]

I think it would be 1/2. Because, there's a 50/50 chance of it landing in either side.

The increase or decrease in the price of a stock between the beginning and the end of a trading day is assumed to be an equally

gayaneshka [121]

Answer:

The probability that a stock will show an increase in its closing price on seven consecutive days is 0.78%.

Step-by-step explanation:

In each day, there are only two possible outcomes for the stock. Either it increases, or it decreases. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem, we have that

There are 7 days, so $n = 7$ .

The increase or decrease in the price of a stock between the beginning and the end of a trading day is assumed to be an equally likely random event. This means that $p = 0.5$ .

What is the probability that a stock will show an increase in its closing price on seven consecutive days?

This is $P(X = 7)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 7) = C_{7,7}.(0.5)^{7}.(0.5)^{0} = 0.0078$

The probability that a stock will show an increase in its closing price on seven consecutive days is 0.78%.
