Answer:

"I think of a number, take away 1 and multiply the result by 3" can be written algebraically as:

3(x - 1)

where x is the unknown number that is being thought of.

We subtract 1 from x because the problem asks to "take away 1", and then we multiply the result by 3 because the problem asks to "multiply the result by 3".

So the expression 3(x - 1) represents the result of thinking of a number, taking away 1, and multiplying the result by 3.

The cost of the treat would be 40 pennies.

In mathematics, an expression is a combination of symbols (such as numbers, variables, and operations) that represents a value.

Expressions can be as simple as a single number or variable, or they can be more complex, involving multiple operations and variables. They can also include functions, exponents, and other mathematical concepts.

Chloe started with 74 pennies and lost 10, so she has 74 - 10 = 64 pennies left. The treat costs 5/8 of her remaining pennies,

Calculate the cost by multiplying 5/8 by 64:

Answer:

Step-by-step:

1.The probability of picking a brown ball can be calculated as:

Probability of picking a brown ball = Number of brown balls / Total number of balls

Number of brown balls = 25

Total number of balls = 13 + 25 = 38

Probability of picking a brown ball = 25/38

Probability of picking a brown ball is approximately 0.658 or 65.8%

Therefore, the probability of Jaide picking a brown ball from the jar is approximately 0.658 or 65.8%.

2.There are four kings in a pack of 52 cards (one king for each suit). Therefore, the probability of drawing a king from a pack of 52 cards can be calculated as:

Probability of drawing a king = Number of kings / Total number of cards

Number of kings = 4

Total number of cards = 52

Probability of drawing a king = 4/52

Probability of drawing a king is approximately 0.077 or 7.7%

Therefore, the probability of getting a king when drawing a card at random from a pack of 52 cards is approximately 0.077 or 7.7%.

Therefore, it takes four days for the rain gauge to be free of water. The answer is option D, day 7.

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation usually contains one or more variables, which are symbols that represent unknown or varying quantities. The values of the variables that satisfy the equation are called the solutions of the equation.

Here,

Let's start by finding out how much water is left in the gauge after one day of evaporation and addition. If the rain gauge had 10 inches of water at the start of the week, then after one day:

4 inches of water would have evaporated, leaving 10 - 4 = 6 inches of water.

2 more inches of rain would have fallen, bringing the total to 6 + 2 = 8 inches of water.

So after one day, the rain gauge has 8 inches of water.

Now we need to repeat this process until there is no water left in the gauge.

After the second day:

4 more inches of water would have evaporated, leaving 8 - 4 = 4 inches of water.

2 more inches of rain would have fallen, bringing the total to 4 + 2 = 6 inches of water.

After the third day:

4 more inches of water would have evaporated, leaving 6 - 4 = 2 inches of water.

2 more inches of rain would have fallen, bringing the total to 2 + 2 = 4 inches of water.

After the fourth day:

4 more inches of water would have evaporated, leaving 4 - 4 = 0 inches of water.

2 more inches of rain would have fallen, but it would not have filled the gauge since it was already empty.

The surface area of the figure, given the diameter of the base and the height, would be 353.43 square millimeters.

We can use the formula for the surface area of a cone:

Surface Area = πr² + πr√(r² + h²)

where r is the radius of the base and h is the height of the cone.

Since the diameter of the base is 9mm, the radius is half of that, or 4.5mm. The height of the cone is 20mm. Plugging these values into the formula, we get:

Surface Area = π(4.5)² + π(4.5)√(4.5² + 20²)

Surface Area = π(20.25) + π(4.5)√(436.25)

Surface Area = 353.43 millimeters²

Answer: Marvin walks a total of 4 + 3 + 4 = 11 blocks.

To find how far he is from his starting point, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the 4 blocks north and 3 blocks east form the legs of a right triangle, and the distance Marvin is from his starting point is the hypotenuse.

So we can calculate it as follows:

distance = sqrt(4^2 + 3^2) = sqrt(16 + 9) = sqrt(25) = 5

Therefore, Marvin is 5 blocks from his starting point.

The measure of the angle LAF is 4°

Explain the term angle

An angle is a geometric figure formed by two rays that share a common endpoint called a vertex. The rays are usually referred to as the sides of the angle. Angles are measured in degrees or radians and are used in various fields, including mathematics, physics, and engineering, to describe and calculate shapes and movements.

According to the given information

Here we have:

mYL + mSF = 360°

We also know that mYS = 48 degrees and mLF = 160 degrees. Since arc YS and arc LF are on the same circle, they must add up to 360 degrees. Therefore:

mYS + mLF + mYSF = 360°

Substituting the given values, we have:

48 + 160 + mYSF = 360°

Simplifying and solving for mYSF, we get:

mYSF = 152°

Now we can find the measure of the central angle LSF that intercepts arc LF by subtracting mYSF from the measure of the arc LF:

mLF - mYSF = 160 - 152 = 8°

Finally, we can find the measure of angle LAF by dividing the central angle LSF in half, since angle LAF is an inscribed angle that intercepts arc LF:

mLAF = 1/2 * mLSF = 1/2 * 8 = 4°

Therefore, m/LAF = 4 °

Using laws of exponents I distributed the exponent to the fraction and solved.

The correct answer is: The IQR of 13 is the most accurate to use, since the data is skewed. (Option B).

The correct answer is: Together, Streetcar and Cable Car are the preferred transportation for 168 residents. (Option A).

The correct answer is: The IQR is the best measure of variability, and it equals 6.

1. Since the data is skewed, it is not appropriate to use the range as a measure of variability. The range is sensitive to extreme values and can be misleading in skewed data. The interquartile range (IQR) is a better measure of variability for skewed data since it is not affected by extreme values. Therefore, the charity should use the IQR of 13 as the measure of variability for this data.

2. From the circle graph, we can draw the following conclusion:

Together, Streetcar and Cable Car are the preferred transportation for 27% + 15% = 42% of the residents. 42% of 400 is 168 residents.

3. The line plot shows that the data is discrete and not continuous. Also, the data is not normally distributed and is skewed. Therefore, the range is not an appropriate measure of variability. The interquartile range (IQR) is a better measure of variability for skewed data. The IQR is the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of the data.

The 10,000 cubic yards of snow were spread evenly over the rectangular football field, the layer of snow would be approximately 1.56 yards deep.

To determine how many yards deep the layer of snow would be if spread evenly over the rectangular football field, we need to know the volume of the snow and the area of the football field.

First, let's find the area of the football field. Assuming standard dimensions for a football field, we have:

Length = 120 yards

Width = 53.3 yards

Area = Length x Width

Area = 120 yards x 53.3 yards

Area = 6,396 square yards

Now, let's find the volume of the snow. We are given that 10,000 cubic yards of snow were removed from the downtown area, so the volume is:

Volume = 10,000 cubic yards

Finally, to find the depth of the layer of snow, we can divide the volume of the snow by the area of the football field:

Depth = Volume / Area

Depth = 10,000 cubic yards / 6,396 square yards

Depth ≈ 1.56 yards

Therefore, if the 10,000 cubic yards of snow were spread evenly over the rectangular football field, the layer of snow would be approximately 1.56 yards deep.

55% of the claims are within one standard deviation of the mean claim size.

To find the percentage of claims that are within one standard deviation of the mean claim size, we first need to calculate the mean and standard deviation of the distribution.

The mean claim size is:

u = (20 × 0.10) + (30 × 0.10) + (40 × 0.10) + (50 × 0.20) + (60 × 0.15) + (70 × 0.10) + (80 × 0.25) = 54

The variance can be calculated as follows:

s^2 = [[tex](20-54)^{2}[/tex] × 0.10] + [[tex](30-54)^{2}[/tex] × 0.10] + [[tex](40-54)^{2}[/tex] × 0.10] + [[tex](50-54)^{2}[/tex] × 0.20] + [[tex](60-54)^{2}[/tex] × 0.15] + [[tex](70-54)^{2}[/tex] × 0.10] + [[tex](80-54)^{2}[/tex] × 0.25] = 340

The standard deviation is the square root of the variance:

s = √340 ≈ 18.44

To find the percentage of claims that are within one standard deviation of the mean claim size, we need to find the range of claim sizes that fall within the interval (u - s, u + s).

(u - s) = 54 - 18.44 = 35.56

(u + s) = 54 + 18.44 = 72.44

We can see from the table that the claim sizes 40, 50, 60, and 70 fall within this range, and their probabilities add up to:

0.10 + 0.20 + 0.15 + 0.10 = 0.55
