According the inscribed angle theorem, t = 76°. The inscribed angle theorem postulates that the inscribed angles subtended by the same arc are equal.

Step 1: Note that the line segment YX can be used to create an arc.

Step 2: Since the vertexes 76° and t° are subtended by the same arc, that makes t = 76°.

Note: An arc, line segment, or other portion of a curve subtends an angle when its two rays pass through the endpoints of that arc, line segment, or curve section.

So the correct answer is m∠t = 76°

The probability that an M&M picked at random is brown is 30% if m&m picked brown at random. Probability refers to the measure of the likelihood of an event occurring.

To find the probability that an M&M picked at random is brown, we need to consider the given percentages of the other colors. Given that 20% are yellow, 20% are red, 10% are orange, 10% are blue, and 10% are green. First, let's add these percentages together:
20% + 20% + 10% + 10% + 10% = 70%

Since the total percentage should add up to 100%, we can find the percentage of brown M&Ms by subtracting the sum of the other colors' percentages from 100%:
100% - 70% = 30%
So, the probability that an M&M picked at random is brown is 30%.

The set of numbers whose decimal representations are neither repeating nor terminating is known as the set of irrational numbers.

Irrational numbers are numbers that cannot be expressed as fractions and have non-repeating and non-terminating decimal representations. Examples of irrational numbers include √2, π (pi), and e (Euler's number). These numbers are infinite and non-repeating, meaning their decimal representation goes on forever without following a specific pattern. The proof that √2 is irrational was first demonstrated by the ancient Greeks, and the irrationality of π and e was proven much later in history. Irrational numbers play a significant role in mathematics and are essential for understanding concepts like limits, calculus, and geometry.

What is the mathematical term for the set of numbers whose decimal representations are neither terminating (finite decimal) nor repeating (infinite periodic decimal)?

Answer:

The slope is 5.

Explanation:

In the slope-intercept form of an equation

m is the slope, and b is the y-intercept of the equation.

Now in our case,

therefore, the slope is 5 and the y-intercept is -3.

The simplified expression is 26 - 4x.

To simplify the expression 6 - 4(x - 5), we can apply the distributive property and simplify the terms.

6 - 4(x - 5)

First, distribute -4 to the terms inside the parentheses:

6 - 4x + 20

Now, combine like terms:

(6 + 20) - 4x

Simplifying further:

26 - 4x

Answer: It already tells you what DE= 60

Step-by-step explanation:

Since F is the midpoint of DE that means DF=FE

So create equation \(2x+6+2x+6=4x+12\)

When DF and FE is added your answer should equal DE

So you write the equation \(4x+12=2x+36\) to find x and once x is found substitute your answer for x

\(4x+12(-12)=2x+36(-12)\) subtract 12 on both sides 36-12= 24

\(4x=2x+24\) subtract 2x on both sides 4x-2x=2x

\(2x=24\) divide 2 into both sides 24/2=12 x=12

\(4(12)+12=2(12)+36\)  

4x12=48+12=60   2x12=24+36=60

Answer:

continuous

Step-by-step explanation:

continuous functions do not have such properties.

Answer:

The answer would be : F.

Step-by-step explanation:

for this you should on look at the x axis line.

The left side is the negative side and the right side is the positive side.

As you can see the line from the circle on the negative side of the x axis is going to the positive side.

Meaning that X will be greater than -9

Thus we have this part of the answer so far

-9<x

(Before we proceed remember if the circle is not colored in that means it is either greater than or less then. So you would use these </>. But if it is colored in then it is either less than or equal to OR greater than or equal to. I don't have the symbols on my phone keyboard but they are just "<" or ">" with a line under them.)

The next point on the positive/right side is colored in and going towards the negative/left side therefore, X will be less than or equal to 2.

(2 being where the point is on the x axis line)

so we will get : -9 < x (less than or equal to sign) 2

The mean and standard deviation of the sample proportion are 0.2 and 0.04. The correct option is 0.2 and 0.04.

Based on the information provided, we can infer that the random samples of size 100 were taken from an infinite population with a population proportion of 0.2. This means that 20% of the population exhibits a certain trait or characteristic of interest.

The mean of the sample proportion is also 0.2, which is the same as the population proportion. This suggests that the sample is representative of the population and that the sample was drawn randomly.

The standard deviation of the sample proportion is 0.04, or 4%. This indicates that there is some variability in the sample proportions. However, it is not too high and suggests that the sample is reliable and consistent.

In conclusion, based on the mean and standard deviation of the sample proportion, we can say that the sample is representative of the population and that the estimates obtained from the sample are reliable and accurate. It is important to note that the size of the sample is relatively large (100) and this helps to increase the accuracy and precision of the estimates. The correct option is 0.2 and 0.04.

3y= 7x

Step-by-step explanation:

you don't know the Pythagoras formula yet ?

this is something you need to remember for life. this you will encounter everywhere (not just in school) :

c² = a² + b²

in a right-angled triangle c is the Hypotenuse (the side opposite of the 90° angle). a and b are the legs of the triangle.

4.

the legs of this right-angled triangle are the pole and the ground distance to the cable fixture on the ground.

the cable itself is the Hypotenuse (as the right angle is the angle between the pole and the ground distance).

so,

cable² = 8² + 6² = 64 + 36 = 100

cable = sqrt(100) = 10 m

5.

here we have a right-angled triangle with the direct distance between the points being the Hypotenuse, and the x and y coordinate differences are the legs.

so, we have

distance² = (3 - -3)² + (0 - -1)² = 6² + 1² = 36 + 1 = 37

distance = sqrt(37)

please note that since we are squaring, the direction of the differences and their signs do not matter. the square will turn positive and negative distances into positive numbers.

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. ... Rays and lines cannot be congruent because they do not have both end points defined, and so have no definite length.

The mean is $32.09, the median is $35.99 and the mode will be $49.99.

The mean cell phone case price can be calculated using the formula:

mean = (sum of all prices) / (number of prices)

To find the sum of all prices, we can use sigma notation:

sum = 19.99 + 8.99 + 35.99 + 49.99 + 49.99 + 39.99 + 99.99 + 79.99 + 35.99 + 19.99 + 49.99 + 29.99 + 49.99 + 54.99 + 35.99 + 49.99 + 19.99 + 8.99 + 29.99 + 35.99$

sum = 674.89$

To find the number of prices, we count the number of items in the list:

number of prices = 21

Finally, we can use the formula to find the mean:

mean = {674.89}/{21} = 32.09$

Frequency Distribution:

Price Frequency

8.99 2

19.99 3

29.99 2

35.99 5

39.99 1

49.99 6

54.99 1

79.99 1

99.99 1

Using the frequency distribution, the mean can be calculated as:

mean = (8.99 * 2 + 19.99 * 3 + 29.99 * 2 + 35.99 * 5 + 39.99 * 1 + 49.99 * 6 + 54.99 * 1 + 79.99 * 1 + 99.99 * 1) / 21 = 32.09

The median is the middle value of the data set when it is arranged in order. To find the median, we need to arrange the prices in order and find the middle value:

8.99, 8.99, 19.99, 19.99, 19.99, 29.99, 29.99, 35.99, 35.99, 35.99, 35.99, 35.99, 39.99, 49.99, 49.99, 49.99, 49.99, 49.99, 49.99, 54.99, 79.99, 99.99

The median is 35.99.

The mode is the value that appears most frequently in the data set. In this case, the mode is 49.99, as it appears 6 times in the data set.
