Step-by-step explanation:

Using the inscribed angle theorems, the measure of the indicated angles are:

1. m∠BOA = 26°

2. m∠BDA = 13°

3. m∠BCA = 13°

Based on the inscribed angle theorem, the following relationships are established:

Given:

Intercepted arc BA = 26°

1. ∠BOA is central angle

Thus:

m∠BOA = 26° (inscribed angle theorems)

2. ∠BDA is inscribed angle.

m∠BDA = 1/2(30) = 13° (inscribed angle theorems)

3. m∠BCA = m∠BDA = 13° (inscribed angle theorems)

Step-by-step explanation:

In general you can always add terms that are similar to each other: similar means that they have the same variables.

For example you can say: 3 bananas + 2 bananas = 5 bananas (3x+2x=5x)

But you can't say; 3 bananas + 2 apples = 5 something (3x+2y=3x+2y : can't add them).

Example in a: 3x+4y+2x+y you have 2 terms with x and 2 terms with y, those are similar and you can add them:

3x+4y+2x+y=6x+5y

Other than this you can't proceed since 6x and 5y aren't similar

Answer:

He spent on fruit after 5 months is $110.

In 15 months he spent $280.

Step-by-step explanation:

Fixed pay for membership is $25

And enrollment fee is $17 for each month.

The equation represents this situation is

y= 17 x + 25

He is going to stop receiving fruits once he spent $280.

Now, to find how much he spent on fruit after 5 months is plugin x as 5 into

y=17x+25 for x

y=17(5)+25

y=85+25

y=110 dollars

Now, to find how many months until $280 is to plug in y as 280 then solve the equation for x.

280 = 17 x+25

Subtract both sides 25

255 =17 x

Divide both sides by 17

x= 15 months

The value of n is 443 inches when using the triangle rule and law of sine.

The formula is given as

a / sin A = b / sin B = c / sin C

In this triangle NOP, we can find the value of angle P

∠N + ∠O + ∠P = 180

57 + 55 + ∠P = 180  : Sum of angles in a triangle is equal 180 degrees

∠P = 180 - 112

∠P = 68

Using law of sine

p/sin P = n/sin N

490/sin68 = n / sin57

n = [(490 × sin 57) / sin 68]

n = 443 inches

The property that is not true for the normal distribution among the given options is: "The mean, median, and mode are all equal."

The normal distribution is characterized by several key properties. It has a bell shape, meaning it is symmetric around its mean. The tails of the distribution asymptotically approach the horizontal axis, which means they gradually decrease in height as they extend toward positive and negative infinity. The area underneath the curve and to the right of the mean is equal to 0.5, not 1. This is because the total area under the curve represents the probability of all possible outcomes and must sum up to 1. Lastly, the mean, median, and mode of the normal distribution are all equal to each other, making them measures of central tendency that coincide.

Therefore, the property that does not hold for the normal distribution is that the area underneath the curve and to the right of the mean is 1, as it is actually 0.5.

The probability of rolling a sum of 12 or smaller than 5 is:

P = 7/36 = 0.194

Each dice has a total of 6 outcomes. Then for rolling two die, the total number of outcomes is:

6*6 = 36

The probability of rolling a sum of 12 or smaller than 5, is equal to the quotient between the number of outcomes that meet the above condition and the total number of outcomes.

There is only one outcome that adds up to 12.

And by looking at the table, we can see that there are 6 outcomes that add up to numbers smaller than 5.

So 7 outcomes meet the condition.

Then the probability is:

P(sum of 12 or <5) = 7/36 = 0.194

A rhombus is a quadrilateral whose all sides are of equal length, and the opposite are parallel to each other.

A rhombus is a quadrilateral whose all sides are of equal length, and the opposite are parallel to each other.

Given the diagonal MO divides the rhombus LMNO, is two isosceles triangles, therefore, ΔLMO and ΔMNO.

Since the triangles are isosceles triangles two of the sides of the triangle will be of the same length. Therefore,

In ΔLMO

LM = LO

In ΔMNO

MN = ON

since it is the property of the rhombus that the length of its adjacent sides is equal, therefore, the LMNO is a rhombus.

Answer:

To find the dependent value for the graph y = 20 - 2x when the independent value is 5, we substitute x = 5 into the equation and solve for y.

y = 20 - 2x

y = 20 - 2(5)

y = 20 - 10

y = 10

Therefore, when x = 5, the dependent value y is 10.

Answer:

To find the dependent value (y) for the given graph y = 20 - 2x when the independent value (x) is 5, we substitute x = 5 into the equation and solve for y.

y = 20 - 2x

Substituting x = 5:

y = 20 - 2(5)

y = 20 - 10

y = 10

So, when x = 5, the dependent value (y) is 10.

To determine the speed, we can use the formula:

speed = distance / time

where distance is measured in feet and time is measured in minutes.

In this case, the distance is 264 feet and the time is 3 minutes. Plugging these values into the formula, we get:

speed = 264 feet / 3 minutes

simplifying, we get:

speed = 88 feet/minute

Therefore, the equipment is traveling at a speed of 88 feet per minute.

The probability that the number's units digit will be less than 5 is 0.5 that it is equal to 1/2.

Probability is a branch of mathematics concerned with numerical descriptions of how likely an event is to occur or how likely a statement is to be true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

There are 10 possible digits, 0, 1, 2, ... 9 that make up the 5-digit number made up of integral values.

There are 5 digits that are less than 5 which are 0, 1, 2, 3, and 4 so the probability will be found by taking only those nubers which have unit's place less than 5,

By probability formula , Probability= no. of favourable outcomes/total no. of outcomes

So probability will be found that will be equal to 5/10, or 1/2

Answer:

41,44,44,51

Step-by-step explanation:

The regression formula estimated when performing a test for the stationarity of a time series variable y is y(t) = α + β*t + ε(t).

a. The null hypothesis of this test is that the time series variable y is non-stationary, meaning it has a unit root.

b. To determine whether two variables are cointegrated, the following steps are typically involved:

1) Identify the two variables: Select two time series variables, denoted as X(t) and Y(t), that are suspected to be related in a long-run equilibrium.

2) Test for unit roots: Conduct unit root tests on both X(t) and Y(t) to determine if they are stationary.

3) Estimate the cointegration regression: If both variables are non-stationary, estimate the cointegration regression model, typically using methods like the Engle-Granger two-step procedure or the Johansen test. This regression model takes the form Y(t) = α + β*X(t) + ε(t).

4) Test for the presence of a cointegrating relationship: Perform hypothesis tests on the estimated coefficients to check if the β coefficient is significantly different from zero, indicating the presence of a cointegrating relationship.

5) Interpret the results: If the null hypothesis of no cointegration is rejected, it suggests that X(t) and Y(t) are cointegrated, meaning they have a long-run relationship.

Cointegration analysis is used to determine whether two variables move together over time, despite being non-stationary individually. It helps in understanding the long-run equilibrium relationship between variables and can be valuable in modeling and forecasting.
