Based on the data in the tables, which conjecture about inscribed and central angles is true include the following: B. If an inscribed angle and a central angle intercept arcs with equal measures, the inscribed angle is half the measure of the central angle.

In Geometry, an arc is a trajectory that is generally formed when the distance from a given point has a fixed numerical value. Generally speaking, the degree measure of an arc in a circle is always equal to the central angle that is present in the included arc.

Additionally, the inscribed angle of a circle is equal to half of the central angle of a circle. Mathematically, this is given by this mathematical expression:

m∠A = 1/2(C)

m∠A = 1/2(100)

m∠A = 50°.

Women make up 64% of the sample and are typically the household's main investment.

There is a correlation between American women and being the main provider in their home.

Descriptive statistics, also known as brief informative coefficients, are used to summarize a specific data collection, which may be a sample of a population or a representation of the entire population. Descriptive statistics include measures of variability and central tendency (spread). Measures of central tendency include the mean, median, and mode, whereas measures of variability include the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.

For instance, the sum of the following data set is 20: (2, 3, 4, 5, 6). A 4 (20/5) is the mean. A data set's mode is the number that appears most frequently, while its median is the value that is in the middle of the range of values. It is the value that separates a data set's higher values from lower values. There are many less common ways to use descriptive statistics, but they are nevertheless essential.

The probability that Marshall wins a prize on his second spin =  0.1875

Consider an event X = the number of spins until Marshall wins a prize.

Given that a prize wheel with 4 segments of equal size, one of which is labeled winner.

So, the sample space n = 4

For given event x, the possible outcomes = 1

Using the formula of probability,

p = x/n

p = 1/4

p = 0.25

So, the probability of success p = 0.25

q = 1 - p

q = 1 - 0.25

q = 0.75

To find the probability that Marshall wins a prize on his 2nd spin.

Using formula, \(P(X = k) = (1 - p)^{k-1}p\)

For  k = 2,

\(P(X = 2) = (1 - 0.25)^{2-1}\times 0.25\)

P(X = 2) = 0.75 × 0.25

P(X = 2) = 0.1875

Thus, the required probability is  0.1875

Answer:

x = 25°

Step-by-step explanation:

Here given a straight line whose angle equals to 180°

2x + 10 + 4x + 20 = 180

group terms like this ↓

2x + 4x + 10 + 20 = 180

simplify all variables ↓

6x + 30 = 180

changing sides changes addition to subtraction ↓

6x = 180 - 30

6x = 150

changing sides changes multiplication to division ↓

x = 150/6

final answer ↓

x = 25°

Answer:

x = 25

Step-by-step explanation:

Angles on a straight line add up to 180°

\(\implies (2x + 10) + (4x + 20) = 180\)

\(\implies 2x + 10 + 4x + 20 = 180\)

\(\implies 6x + 30 = 180\)

\(\implies 6x =150\)

Based on the crocodile skeleton found with a head length of 62 cm and a body length of 380 cm, it is likely that the species was a Saltwater Crocodile (Crocodylus porosus).

According to the given measurements, it is likely that the species was a Saltwater Crocodile (Crocodylus porosus).  This is because Saltwater Crocodiles are known to have larger sizes compared to other species.

To explain why, let's consider the following steps:

1. Compare the head length and body length to average sizes of different crocodile species.
2. Identify the species whose average size is closest to the given measurements.

Saltwater Crocodiles are the largest living species of crocodiles, with males reaching lengths of over 6 meters (20 feet). The head length of 62 cm and body length of 380 cm (3.8 meters) would likely be within the size range for an adult male Saltwater Crocodile. Other species, such as the Nile Crocodile or the American Alligator, typically do not reach such large sizes, making the Saltwater Crocodile a more plausible candidate based on the given measurements.

Step-by-step explanation:

Find how many months are in 4 years, since there are 4 years between her 13th and 17th birthdays.

There are 12 months in a year, so multiply 12 by 4:

12(4)

= 48

So, there are 48 months in 4 years. Since she buys a new teacup every month, this means she will have bought 48 more teacups.

Add this to the 4 teacups she got on her 13th birthday:

48 + 4

= 52

So, on her 17th birthday, she will have A. 52 teacups

The sampling interval is calculated by dividing the digital sampling frequency by the number of samples taken per second.

The sampling interval refers to the time interval between each consecutive sample in a digital signal. It is determined by dividing the digital sampling frequency by the number of samples taken per second. The sampling frequency represents the number of samples captured in one second, while the number of samples per second represents the rate at which the samples are taken. By dividing the sampling frequency by the number of samples per second, we can determine the time interval between each sample.

This is crucial in accurately representing and reconstructing the original analog signal from the digital samples. Therefore, the sampling interval is calculated by dividing the digital sampling frequency by the number of samples taken per second.

(a) The supply when the price is $10 is 18 units. (b) The demand when the price is $10 is 21 units. (c) The equilibrium price is $7, and both the quantity supplied and demanded at this price are 9 units. (d) The supply curve crosses the horizontal axis at the point (4, 0), indicating that at a price of $4, there is no supply of CDs.

(a) To find the supply when the price is $10, substitute p = 10 into the supply equation:

q = 3p - 12

q = 3(10) - 12

q = 30 - 12

q = 18

Therefore, the supply when the price is $10 is 18 units.

(b) To find the demand when the price is $10, substitute p = 10 into the demand equation:

q = -2 + 23

q = 21

Therefore, the demand when the price is $10 is 21 units.

(c) To find the equilibrium price, set the supply equal to the demand and solve for p:

3p - 12 = -2 + 23

3p = 21

p = 7

The equilibrium price is $7. To find the corresponding quantity supplied and demanded, substitute p = 7 into either the supply or demand equation:

For supply:

q = 3p - 12

q = 3(7) - 12

q = 21 - 12

q = 9

For demand:

q = -2 + 23

q = 21

Therefore, at the equilibrium price of $7, both the quantity supplied and demanded are 9 units.

(d) To find where the two lines cross the horizontal axis, set q = 0 and solve for p in each equation:

For supply: q = 3p - 12

0 = 3p - 12

3p = 12

p = 4

For demand: q = -2 + 23

0 = -2 + 23

2 = 23 (not possible)

The economic interpretation of the point (4, 0) on the horizontal axis for the supply equation is that at a price of $4, there is no supply of CDs. This could indicate that the cost of production or other factors make it unprofitable to supply CDs at that price.

Given:

Sam left Malaysia at 12 pm local time.

The flight time was 12 hours.

Malaysia is 7 hours ahead of UK.

To find:

The local time in UK when he arrived.

Solution:

It is given that Sam left Malaysia at 12 pm local time and the flight time was 12 hours.

12 hours after 12 pm is 12 am. It means local time in Malaysia when he reached UK is 12 am.

Malaysia is 7 hours ahead of UK. So, we need to subtract 7 hours from 12 am to get the local time in UK when he arrived.

12 am is midnight. So, 7 hours before 12 am is 5 pm.

12 am - 7 hours = 5 pm

Therefore, the local time in UK when he arrived is 5 pm.

a) if distribution

for f to be a probability density function , has to comply with the requirement that the sum of the probability of all the posible states is 1 , then

P(all possible values) = ∫∫f (y1, y2) dy1*dy2 = 1

Step-by-step explanation:

The total number of possible outcomes containing exactly 3 heads when a coin is flipped eight times where each flip comes up either heads or tails are 56.

There are two possible outcomes i.e. heads and tails when a coin is flipped. If the coin is flipped 8 times, the total number of outcomes will be:-

\(2^8=256\)

We need exactly 3 heads , and hence exactly 5 tails, like

H H H T T T T T

Here H represents heads and T represents tails.

But H and T can come in any combination, for example:-

H T H H T T T T

Hence, total possible outcomes containing exactly 3 heads and 5 tails will be determined using the combinations formula :-
