Its higher than a 5 which turns it into a 10

Answer:

9, 40, 41.

Step-by-step explanation:

We can derive this by simply analyzing all of the answer choices and eliminating those that do not work using the Pythagorean formula: a²+b²=c²

1²+3²≠10²

4²+5²≠9²

9²+40²= 41²

16²+30²≠44²

When these are plugged into the calculator, we can see that only answer 3 satisfies the formula, making it a Pythagorean triple.

Answer:

9,40,41 is a Pythagorean triple

Step-by-step explanation:

Pythagorean triples are integers that're all positive and they don't have a common divisor larger than 1

The arc measure of CAD is 296 degrees.

1. Find k by setting angle DPE to 90 degrees:

33k - 9 = 90

33k = 99

k = 3

2. Calculate angle CPD using the value of k:

angle CPD = 20k + 4

angle CPD = 20(3) + 4

angle CPD = 64

3. Determine angle CBP by subtracting angle CPD from 90 as angle APB is 90 degree:

CBP = 90 -  CPD

CBP = 90 - 64

CBP = 26

4. Finally, calculate the arc measure of CAD by adding the arc measures of CBP, APB, EPD, and APE:

Arc measure of CAD = ∠CBP + ∠APB+ ∠EPD + ∠APE

Arc measure of CAD = 26 + 90 + 90 + 90

Arc measure of CAD = 296

Hence, the arc measure of CAD is 296 degrees.

Complete question:

In the figure below, AD and BE are diameters of circle P.

You didn’t not show what is the relation between the expressions so I assumed it’s equall

Answer:

(x,y) = (3, 1/2)

Step-by-step explanation:

This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations..

To solve this, add the equations;

x + 2x + 2y - 2y = 4 + 5

3x = 9

x = 3

substitute the value of x into the first equation,

3 + 2y = 4

2y = 4 -3

2y = 1

y = 1/2

Answer:

9.5 months

Step-by-step explanation:

We would be using the expression

y = abⁿ

Where

a = starting number = 8 rabbits

b = rate of change = the number of rabbits doubles = 2

n = number of time intervals that has passed = unknown = number of months

y = rabbit population = 5800

y = abⁿ

5800 = 8 × 2ⁿ

Divide both sides by 8

5800 ÷ 8 = 2ⁿ

725 = 2ⁿ

n = 9.5 months.

Therefore, the number of months in which the rabbit population would reach 5,800 is 9.5 months

Answer:

The probability of selecting a red  marble, not replacing it, and then selecting a green marble from the bag is 24/95

Step-by-step explanation:

Number of red marbles = 12

Number of green marbles = 8

Total number of marbles = 12+8 = 20

Probability of selecting red marble =[tex]\frac{12}{20}[/tex]

Since it is the case of no replacement

Remaining marbles = 20-1 = 19

Number of red marbles = 12-1=11

Number of green marbles = 8

Probability of selecting green marble =[tex]\frac{8}{19}[/tex]

So, the probability of selecting a red  marble, not replacing it, and then selecting a green marble from the bag =[tex]\frac{12}{20} \times \frac{8}{19}=\frac{24}{95}[/tex]

Hence the probability of selecting a red  marble, not replacing it, and then selecting a green marble from the bag is 24/95

Answer:

Answer :

The surface area will increase by 9

Step-by-step explanation :

This problem bothers on the mensuration of solid shapes, a cylinder

Step one

We know that the surface area of a cylinder is given as

A= 2πrh + 2πr²

A= 2π(rh + r²)

Since the radius and the height is tripled r=3r, h= 3h

A= 2π(3r*3h + (3r)²)

A= 2π(9rh + 9r²)

Factoring 9 out we have

A= 9*2π(rh + r²)

Hence the surface area will increase by 9

Step-by-step explanation:

Ratios are in proportion

Let x be number of apples

2:3 = x:15

[tex]\frac{2}{3}=\frac{x}{15}\\\\\frac{2}{3}*15=x\\\\2*5=x\\10=x\\[/tex]

Mike should have 10 apples

If Mike has 15 bananas, he would have 10 apples based on the ratio of 2 apples to 3 bananas.

To solve the problem, we start by understanding the given ratio of apples to bananas: 2 apples for every 3 bananas. This can be expressed as the fraction 2/3.

Now, we need to determine how many apples Mike would have if he possesses 15 bananas.

Therefore, if Mike has 15 bananas, he would have 10 apples.

Answer: The correct option is the first question; How many times did we buy a school lunch last week?

Step-by-step explanation: When collecting data for the purpose of statistics and data analyses, the exercise involved goes beyond just asking questions. It is actually about asking questions that would provide data or information with a measure of variability. That would help in deciding which data can be best suited to represent the entire data collected.

The question how many days were in last month is not a statistical question because the answer is pretty much straight forward. The number of days in the previous month cannot vary, it will always be the same, hence the answer would be not be useful for any kind of statistical analyses.

Also, asking "Is your favorite number 5?" is not a statistical question because the answer is a yes or no. This does not allow for any kind of statistical analyses. Its as good as a 'dead end.'

However, asking how many times we bought a school lunch last week is a statistical question because the data collected would have a good measure of variability. That is, the data cannot be the same for all respondents. Unlike in the second question where the answer is already known and unchangeable, the answer to this question is not going to be a fixed one and as the respondents provide varying answers, you can now begin to measure the point at which all the answers are likely to agree (measure of central tendency) which is a basic part of statistics.

Answer: it's option b.

Step-by-step explanation:

[tex]x^{\frac{2}{12} } y^{\frac{8}{12}}[/tex] is the expression using rational exponents with a common denominator of  [tex]\sqrt[6]{x} \sqrt[4]{y^{3} }[/tex]

A number system is defined as a system of writing to express numbers.

The given expression is [tex]\sqrt[6]{x} \sqrt[4]{y^{3} }[/tex]

The square root is nothing but power of 1/2

So we can write these as

[tex]\sqrt[6]{x} \sqrt[4]{y^{3} }[/tex]

[tex]x^{\frac{1}{6} } y^{3}^{\frac{1}{4} }[/tex]

As we need to write the exponents as common denominator.

[tex]x^{\frac{2}{12} } y^{\frac{8}{12}}[/tex]

Hence, [tex]x^{\frac{2}{12} } y^{\frac{8}{12}}[/tex] is the expression using rational exponents with a common denominator of  [tex]\sqrt[6]{x} \sqrt[4]{y^{3} }[/tex]

Answer:

unlikely,likely,and certain

Step-by-step explanation:

The probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A is often written as P ( A ) P(A) P(A)P, left parenthesis, A, right parenthesis.Probability. Probability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .Examples of Probability. ... Probability can be expressed in a variety of ways including a mathematically formal way such as using percentages. It can also be expressed using vocabulary such as "unlikely," "likely," "certain," or "possible." Explore several probability examples.And an event is one or more outcomes of an experiment. Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes.

Answer:

The probability is 0.31

Step-by-step explanation:

In this question, we are tasked with calculating the probability that a random plumber called at Denver will charge an amount greater than $86 given the mean and the standard deviation.

Firstly, we calculate the standard score of $86 using the mean and the standard deviation.

Mathematically;

z-score = (x-mean)/SD

where x = 86, mean = 84 and SD = 4

z-score = (86-84)/4 = 2/4 = 0.5

Hence, we want to calculate P(z ≥ 0.5)

Using standard table

P( (z ≥ 0.5) = 1 - P(z ≤ 0.5) = 1 - ( 0.19146 + 0.5) = 0.30854

To the nearest hundredth = 0.31
