To cover a 2000 sq ft wall, we will need 5 gallons of paint.

what is area?

Area is the measure of the size of a two-dimensional surface or region, expressed in square units. It is a fundamental concept in geometry and is used to quantify the amount of space inside a shape, such as a square, rectangle, triangle, or circle. The unit of measurement for area varies depending on the system used, but in the International System of Units (SI), the standard unit of area is the square meter (m²). In everyday life, we often use other units of area such as square feet, square inches, or square centimeters.

To find the conversion factor, we need to divide the number of square feet by the number of square feet covered by one gallon of paint:

Conversion factor = 1 gallon / (400 sq ft/gallon)

So, for a wall that is 2000 sq ft, we can use this conversion factor to find the number of gallons of paint needed:

Number of gallons = (2000 sq ft) / (400 sq ft/gallon) = 5 gallons

Therefore, to cover a 2000 sq ft wall, we will need 5 gallons of paint.

The graph that shows the possible numbers of cookies and brownies they expect to sell is the first graph.

Option A is the correct answer.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Number of chocolate chip cookies = x

Number of brownies = y

Total number of items at most = 600

Now,

x + y = 600 ____(1)

The number of possible brownies.

y ≥ 3/4 x 600

y ≥ 3 x 150

450 ≤ y ≤ 600 _____(2)

The number of possible cookies.

0 ≤ x ≤ 150 _____(3)

Now,

Graphing (1), (2), and (3) we get the first graph.

The volume of a sphere is calculated using the formula volume = 4/3πr³ where r is the sphere's radius.

Given that:

Ball A = diameter 7cm, mass 1.742kg

Ball B = diameter 6cm, mass 1.040kg

As we know that,

volume of a sphere =4/3πr³

1) For Ball A,

volume of a Ball A = 4/3π(3.5)³

volume of a Ball A = 179.6 cm³

given mass for Ball A is 1.742 kg = 1742 g.

So, Density = \(\frac{mass}{volume}\)

     Density of Ball A will be 9.7 g/cm³.

2) For Ball B,

volume of a Ball B = 4/3π(3)³

volume of a Ball B = 113.11 cm³

The probability that both players show rock in the first round is 1/9 or 0.1111 (rounded to four decimal places).

In rock, paper, scissors there are three possible outcomes for each player: rock, paper, or scissors. Assuming both players choose randomly and independently of each other, each player has a 1/3 chance of showing rock in the first round.

To find the probability that both players show rock in the first round, we can use the multiplication rule of probability for independent events. The multiplication rule states that the probability of the intersection of two independent events is the product of their probabilities.

Therefore, the probability that both players show rock in the first round can be calculated as follows:

P(both show rock) = P(player 1 shows rock) x P(player 2 shows rock) P(both show rock) = 1/3 x 1/3 P(both show rock) = 1/9

So the probability that both players show rock in the first round is 1/9 or approximately 0.111.

Answer:

\(Mean = 53.25\)

Step-by-step explanation:

Given

Low Temperature : 40−44 || 45−49 ||  50−54 || 55−59 || 60−64

Frequency: --------------- 3 -----------6----------- 1-----------3--- -----7

Required

Determine the mean

The first step is to determine the midpoints of the given temperatures

40 - 44:

\(Midpoint = \frac{40+44}{2}\)

\(Midpoint = \frac{84}{2}\)

\(Midpoint = 42\)

45 - 49

\(Midpoint = \frac{45+49}{2}\)

\(Midpoint = \frac{94}{2}\)

\(Midpoint = 47\)

50 - 54:

\(Midpoint = \frac{50+54}{2}\)

\(Midpoint = \frac{104}{2}\)

\(Midpoint = 52\)

55- 59

\(Midpoint = \frac{55+59}{2}\)

\(Midpoint = \frac{114}{2}\)

\(Midpoint = 57\)

60 - 64:

\(Midpoint = \frac{60+64}{2}\)

\(Midpoint = \frac{124}{2}\)

\(Midpoint = 62\)

So, the new frequency table is as thus:

Low Temperature : 42 || 47 ||  52 || 57 || 62

Frequency: ----------- 3 --||- -6-||- 1-||- --3- ||--7

Next, is to calculate mean by

\(Mean = \frac{\sum fx}{\sum x}\)

\(Mean = \frac{42 * 3 + 47 * 6 + 52 * 1 + 57 * 3 + 62 * 7}{3+6+1+3+7}\)

\(Mean = \frac{1065}{20}\)

\(Mean = 53.25\)

The computed mean is greater than the actual mean

Answer:

44

Step-by-step explanation:

We are given:

ab/c = 2 ---------------(1)

bc/a = 4 ---------------(2)

ac/b = 6 ---------------(3)

Multiplying (1) and (2):

ab*bc / ac = 8

b² = 8

Multiplying (2) and (3):

bc*ac/ab = 24

c² = 24

Multiplying (1) and (3):

ac*ab/bc = 12

a² = 12

Now, finding the value of a² + b² + c²:

8 + 24 + 12 = 44 (replacing the values of a² , b² and c²)

Hence, a² + b² + c² = 44

Answer:

The value of x is 21.

Step-by-step explanation:

Since this is a right angle triangle, you can apply Pythagoras theorem, side² + side² = hypo² :

(x + 3)² + 10² = (x + 5)²

x² + 6x + 9 + 100 = x² + 10x + 25

x² + 6x + 109 - x² - 10x - 25 = 0

-4x + 84 = 0

-4x = -84

4x = 84

x = 84 ÷ 4

x = 21 units

First, we can multiply each number by 100 to eliminate the decimal part:

29.95 * 100 = 2995

12.25 * 100 = 1225

We can do it because 100/100 = 1 and the division is not altered.

Then, we have the following division:

1. Find a value that you can multiply by 1225 that is near or exactly 2995. After this, multiply the value by 1225 and subtract the result from 2995 (dividend).

Try with 2:

Then 2 x 1225 = 2450

_2____

1225 | 2995

- 2450

----------

545

Now the rest 545 is less than the divisor (1225). We can also see that we do not have more numbers besides the last digit of the dividend (2995). In this case, we can add a zero beside 545 to get the decimal part of the division.

We can also have to add a dot at the quotient.

That is:

The probability that a sample of size n = 62 is randomly selected with a mean between 189.7 and 213 is approximately 0.9702.

To find the probability that a single randomly selected value is between 189.7 and 213, we can use the standard normal distribution.

Step 1: Calculate the z-scores for the given values using the formula:

  z = (x - μ) / σ

  For 189.7:

  z1 = (189.7 - 189.7) / 96.7 = 0

  For 213:

  z2 = (213 - 189.7) / 96.7 ≈ 0.2417

Step 2: Utilize a standard typical conveyance table or number cruncher to find the probabilities comparing to the z-scores.

  P(189.7 < X < 213) = P(0 < Z < 0.2417) ≈ 0.0939

Therefore, the probability that a single randomly selected value is between 189.7 and 213 is approximately 0.0939.

To find the probability that a sample of size n = 62 is randomly selected with a mean between 189.7 and 213, we use the central limit theorem. Under specific circumstances, the testing dispersion of the example mean methodologies a typical conveyance

Step 1: Calculate the standard error of the mean (σ_m) using the formula:

  σ_m = σ / sqrt(n)

  σ_m = 96.7 / sqrt(62) ≈ 12.2878

Step 2: Convert the given qualities to z-scores utilizing the equation:

  z = (x - μ) / σ_m

  For 189.7:

  z1 = (189.7 - 189.7) / 12.2878 = 0

  For 213:

  z2 = (213 - 189.7) / 12.2878 ≈ 1.8967

Step 3: Utilize a standard typical conveyance table or mini-computer to find the probabilities relating to the z-scores.

  P(189.7 < M < 213) = P(0 < Z < 1.8967) ≈ 0.9702

Therefore, the probability that a sample of size n = 62 is randomly selected with a mean between 189.7 and 213 is approximately 0.9702.

1) The Point-Slope Formula (y – y1) = m(x – x1)

2) The Slope-Intercept Formula y = mx + b

To determine the equation of a line, you may use two variations of the general form of a line.

These formulas are:

1) The Point-Slope Formula (y – y1) = m(x – x1)

2) The Slope-Intercept Formula y = mx + b

The standard form of a linear equation, also known as the “general form“, is:

ax+by=c

The letters aa, bb, and cc are all coefficients. When using standard form, aa, bb, and cc are all replaced with real numbers. The letter x represents the independent variable and the letter y represents the dependent variable.

A few notes on Standard Form:

Let us now determine the y-intercept. Remember, this is where the line crosses the y-axis and where x=0 To do so, we will substitute 0 for x

3y-5x=30

3y-5(0)=30
