The fraction of washers with thicknesses greater than 2.4 millimeters. We need to understand the normal distribution of washer thicknesses. In a normal distribution, data is centered around the mean value, and the standard deviation (SD) determines the spread.

For this problem, we need the mean thickness and SD of the washers being produced.

Once we have the mean and SD, we can calculate the z-score, which represents the number of standard deviations a data point is from the mean. The formula for the z-score is:

Z = (X - mean) / SD

Where X is the specified thickness (2.4 millimeters in this case). After calculating the z-score, we can use a standard normal distribution table (also known as a z-table) to find the corresponding area to the right of the z-score. This area represents the fraction of washers that are expected to be greater than 2.4 millimeters thick.

Unfortunately, without the mean and standard deviation values, we cannot provide a specific answer to your question. However, once you have those values, you can follow the steps above to find the fraction of washers with thicknesses greater than 2.4 millimeters.

Based on his score last week and his score this week, we can say that Jacob increased his score by 180%

Jacob scored 25 in his test last week and then this week scored 70.

The increase can be found as:

= (New score - Old score) / Old score x 100%

Solving gives:

= (70 - 25) / 25 x 100%

= 180%

In conclusion, Jacob increased by 180%

Step-by-step explanation:

The ratio 1.5 which is read "1.5 to 1" means that the length is 1.5 times the width. So, for example if your paper is 2 inches in width then the length is 1.5 × 2 = 3 inches.

The coordinates of an undefined slope are points that are either the same or have no x-value. In both cases, the slope of a line between these points would be undefined because it would involve dividing by 0, which is not allowed in mathematics. This is because the slope of a line is calculated by dividing the difference in y-coordinates by the difference in x-coordinates, and if the x-coordinates are the same or do not exist, this division would result in an undefined value.

Each customer tastes both formula A and formula B in a randomly assigned order and indicates which one they prefer more.

sample customers = 50

y = 0.5x + 2.5

Step-by-step explanation:

equation of straight line is ) y – y1 = m (x – x1), where y1 and x1 are the coordinates of a given point, , and m is the slope (gradient).

slope (gradient) = (change in y values) ÷ (change in x values)

= (1 - 7) ÷ (-3 - 9)

= -6 ÷ -12

= +0.5.

let's pick one of the coordinates. I will pick (9,7).

y - 7 = 0.5(x - 9)

y - 7 = 0.5x - 4.5

y = 0.5x -4.5 + 7

y = 0.5x + 2.5

Step-by-step explanation:

IF  x-4   is a factor, then putting in x = + 4    will make the polynomial = 0

5 ( 4^3) - 20 (4^2) - 5(4)  + 20   =   0    Yes...it is a factor

\(x - 4 = 0 \\ x = 4 \\ \)

substitute value of x in the function to see if it equals to zero , if not it won't be a factor of the function

\(5 {x}^{3} - 20 {x}^{2} - 5x + 20 = 0 \\ 5(4) ^{3} - 20( {4})^{2} - 5(4) + 20 = 0 \\ 5(64) - 20(16) - 20 + 20 = 0 \\ 320 - 320 - 20 + 20 = 0 \\ 0 = 0\)

so (x-4) is a factor for the function

It is not impossible to construct a frame for a finite population or a target population, but it is impossible to construct a frame for a sampled population.

A frame is a list or map of all the units in a population, which is used to select a sample for a survey or study. If a population is finite, it is possible to list all the units in the population and create a frame. Similarly, if the target population is well-defined and can be identified, a frame can be constructed.

However, if the population is sampled, the frame cannot be constructed because the population is unknown and constantly changing. Therefore, it is impossible to construct a frame for a sampled population.

To prove that the two triangles are similar, we can use the Angle-Angle (AA) similarity theorem, which states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

In this case, we have angle MCD in the smaller triangle and angle MDC in the larger triangle, which are congruent because they are vertical angles. We also have angle CMD in the smaller triangle and angle CDM in the larger triangle, which is congruent because they are both right angles. Therefore, by the AA similarity theorem, the two triangles are similar.

To find the length x, we can use the fact that the corresponding sides of similar triangles are proportional. Let's use the ratio of corresponding sides CM and DC in the smaller triangle to MC and CD in the larger triangle:

CM/DC = MC/CD

Substituting the given values, we get:

x/120 = tan 49°/tan 41°

Solving for x, we get:

x = 210 yd * tan 49°/(tan 49° + tan 41°) ≈ 124.8 yd

Therefore, the length x is approximately 124.8 yards.

According to the question, given that

After one week, Reggie has 195 trade cards. He buys 16 more trade cards every week.

he have trading cards in the 12th week = 195 + 16 * (12 - 1)

In response to the query, assuming that

Reggie has 195 trade cards after a week. Each week, he purchases 16 additional trading cards.

he have trading cards in the 12th week = 195 + 16 * (12 - 1)

                                                                   = 195 + 16 * 11

Answer:

Step-by-step explanation:

The expression 3⁻⁶ × (3⁴ ÷ 3⁰)² value is 9 which is 3².

To simplify the given expression: 3⁻⁶ × (3⁴ ÷ 3⁰)², let's break it down step by step:

First, let's simplify the exponent expressions within the parentheses:

3⁴ = 81 (because 3⁴ = 3 × 3 × 3 × 3 = 81)

3⁰ = 1 (because any number raised to the power of 0 is 1)

Now, we can rewrite the expression with the simplified exponents:

3⁻⁶ × (81 ÷ 1)²

Next, simplify the division within the parentheses:

81 ÷ 1 = 81

Now, the expression becomes:

3⁻⁶ × 81²

Simplify the exponent:

81² = 6561 (because 81 × 81 = 6561)

Now, the expression becomes:

3⁻⁶ × 6561

1/729 × 6561

6561/729

dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 9:

729/81

We get 9 which is equal to 3².
