Step-by-step explanation:

You would do 2 times 2 to get 4cm.

Answer:

[tex]4cm^{2}[/tex]

Step-by-step explanation:

The formula for working out the area of a square/rectangle is Length multiplied by the width. To work this out you would simply multiply 2 by 2, which gives you 4. This is because a square would have 4 identical sides and that the formula is length multiplied by the width.

1) Multiply 2 by 2.

[tex]2*2=4cm^{2}[/tex]

Answer:

Step-by-step explanation:

First subtract 3000000 and 50000, which equals 2500000.

Then divide 2500000 and 33388, in order to find the number of years, which equals: 74.877201.

Add 74.877201 to 1944, to find out what year the circulation will reach 3 million, the answer is 2018.877. Round up to the nearest year, so 2019.

In order to find the circulation in 2006, first subtract 2006 and 1944, which equals 62 years, then multiply 62 years by 33388 , which equals 2070056. Add 500000 to 2070056. The answer is 2570056.

A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4StartRoot 3 EndRoot cm and an area of 12StartRoot 3 EndRoot cm2.

What is the volume of the pyramid?

My answer:

As we know, The volume of a pyramid = [tex]\frac{1}{3}[/tex]base area × its height

Given:

=> The area of the base is [tex]12\sqrt{3}[/tex] [tex]cm^{2}[/tex]

We use: [tex]tan(30) = \frac{BC}{AC}[/tex]

<=> BC = [tex]4\sqrt{3}*tan(30)[/tex]

= 4 cm

And BC is the height of the the pyramid

=> The volume of a pyramid = [tex]\frac{1}{3}[/tex] [tex]12\sqrt{3}[/tex] [tex]cm^{2}[/tex] * 4 cm

= [tex]16\sqrt{3}[/tex] [tex]cm^{3}[/tex]

Answer:

D, 342 meters

Step-by-step explanation:

We can use the definition of sines to solve the problem. Remember, sine = opposite leg over the hypotenuse of the triangle.

[tex]sin(<Q)= \frac{RS}{QR} \\[/tex]

Then, we can substitute QR for 1,000 and [tex]<Q[/tex] for 20 degrees and solve like so:

[tex]sin(20) = \frac{RS}{1,000}[/tex]

[tex]RS = 1000 (sin(20))\\\ RS = 1000(0.342)\\\\RS= 342.0201[/tex]

Rounding that number, we get 342 meters. Hope this made sense!

Answer: D. 342 m

Step-by-step explanation:

The given triangle is a right angle triangle since angle S is 90°.

From the given right angle triangle,

QR represents the hypotenuse of the right angle triangle.

With m∠Q as the reference angle,

QS represents the adjacent side of the right angle triangle.

RS represents the opposite side of the right angle triangle.

To determine RS, we would apply

the Sine trigonometric ratio.

Sin θ, = opposite side/hypotenuse. Therefore,

Sin 20 = RS/1000

RS = 1000Sin20 = 1000 × 0.342

RS = 342 m

Answer:

196 lbs is the maximum weight.

Step-by-step explanation:

7 × 13 = 91 lbs (this is the amount he added by the 13th week)

91 + 105 = 196 lbs (this is the amount he added and the amount he had. giving us the finished product.)

Calculate Jason's maximum bench press weight after 13 weeks with a weekly increase of 7 pounds. Jason will be able to bench press a maximum weight of 196 pounds.

Jason's maximum bench press weight: 105 pounds

Weekly increase: 7 pounds

Number of weeks: 13

To calculate the maximum weight after 13 weeks:

First week: 105 + 7 = 112 pounds

Second week: 112 + 7 = 119 pounds

Continue this pattern for 13 weeks.

Result: After 13 weeks, Jason will be able to bench press a maximum weight of 196 pounds.

Answer:

The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.

Step-by-step explanation:

In a regular polygon all the sides are equal and also all the angles are equal. The sum of the interior angle of a polygon can be calculated with the following formula;

sum of interior angle = (n−2) × 180°

where

n = number of sides

The sum of the interior angle should be less than 7500 and greater than 7201.

sum of interior angle = (n−2) × 180°

less than 7500 and greater than 7201 = (43 - 2) × 180

less than 7500 and greater than 7201 = 41 × 180

less than 7500 and greater than 7201 = 7380 °

The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.

statistics is defined as:

the branch of mathematics dealing with data collection, organization, analysis, interpretation and presentation.

Final answer:

Statistics is a mathematical discipline focused on data collection, analysis, interpretation, and presentation. It includes both the process of dealing with numerical data and the resulting numerical facts used to make decisions. The field consists of descriptive statistics and statistical inference, which help understand and compare data for informed decision-making.

Explanation:

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, and presentation of numerical data. It encompasses the entire process from gathering the data to drawing conclusions based on the numerical information obtained. Statistics can also refer to the numerical facts themselves, which are derived from these processes. The field is divided into two key areas: descriptive statistics, which summarizes data from a sample using indexes such as mean or standard deviation, and statistical inference, which makes predictions about a population based on a sample of data.

Statistics are not confined to mere numbers; they represent a comparison and understanding of numerical data. These comparisons help us make informed decisions in various fields, from public policy to medicine. For example, statistics can tell us the percentage increase in a population over a decade, enabling policymakers to plan resources accordingly. Statistics is integral to our daily lives, even though many may not realize its pervasive influence.

Answer:

23. x = 11.1 // 24. x = 21.4

Step-by-step explanation:

23.

Observe which sides are known and needed. 15 is the hypotenuse and x is the adjacent side. The trigonometric function that connects both the hypotenuse and the adjacent side is cosine. Using the degree, set up the equation as so: cos(42) = x/15. (Because cosine is adjacent over hypotenuse, x is over 15). Isolate x to solve for it by multiplying both sides by 15. cos(42) * 15 is 11.1

24.

Observe which sides are known and needed. x is the hypotenuse and 11 is the opposite side. The trigonometric function that connects both the hypotenuse and the opposite side is sine. Using the degree, set up the equation as so: sin(31) = 11/x. (Because sine is opposite over hypotenuse, 11 is over x). Isolate x to solve for it by multiplying both sides by x and then dividing both sides by sin(31). 11 divided by sin(31) is 21.4

To calculate the probability of the temperature being in the 90s next year, you take the number of times the temperature was in the 90s over the past 15 years and divide by 15. This gives the probability, but it is just an estimate as weather is unpredictable.

To determine the probability that next year’s temperature will be in the 90s, you firstly need to know the number of times the temperature was in the 90s over the past 15 years. After that, you divide that by the total number of years observed (15 years). This gives a fraction or a decimal which represents the probability.

For instance, if the temperature was in the 90s for 7 out of the 15 years, the probability would be 7/15, or approximately 0.47.

Please remember, this result is an estimate as weather is influenced by many unpredictable factors. Therefore, the past trends cannot guarantee future conditions but it gives a rough estimate.

To model the population of foxes t months since the beginning of Alyssa's study, we can use the equation P(t) = P(0) - (1/18t), where P(0) is the initial population of 185,000 foxes.

To write a function that models the population of foxes t months since the beginning of Alyssa's study, we need to determine the rate at which the population decreases over time. Given that the population loses 1/18 of its size every 22 months, we can use this information to develop an equation. Let P(t) represent the population of foxes at time t, and let P(0) be the initial population of 185,000 foxes.

Since the population loses 1/18 of its size every 22 months, the rate of decrease can be calculated as 1/18 per 22 months. This can be written as -1/18 per month or -1/18t per month. Hence, the equation that models the population is P(t) = P(0) - (1/18t).
