The average productivity of this production process is approximately 1.96 units per labor hour.

The average productivity, in terms of the average number of units per labor hour, for a production process can be determined using the expected value approach. In this case, the random variable X represents the number of units produced each week, with corresponding probabilities. The average production, or expected value, can be calculated by summing each production value multiplied by its probability. Finally, the productivity can be obtained by dividing the average production by the number of labor hours needed.

In this scenario, the production values are 99, 104, and 116, with corresponding probabilities of 0.1, 0.7, and 0.2, respectively. To find the average production, we multiply each production value by its probability and sum the results:

Average production = (99 * 0.1) + (104 * 0.7) + (116 * 0.2) = 9.9 + 72.8 + 23.2 = 105.9

Given that the number of labor hours needed is 54 units per labor hour, we can calculate the average productivity:

Productivity = Average production / Labor hours = 105.9 / 54 ≈ 1.96

The average productivity of this production process is approximately 1.96 units per labor hour.

By converting the given amount of yarn into feet, we found that Muhammad has 6 feet of yarn, which is more than the required 6 feet to make a scarf. Therefore, he will be able to make a scarf with the yarn he has.

To determine whether Muhammad has enough yarn to make a scarf, we need to convert the given amount of yarn into feet.

1 yard is equal to 3 feet, and 1 foot is equal to 12 inches. Therefore, there are 36 inches in 1 yard.

Given that Muhammad has 2 yards and 3 inches of yarn, we can convert this into feet:

2 yards = 2 * 3 = 6 feet

3 inches = 3/12 = 0.25 feet

Adding these two amounts together, Muhammad has a total of 6 + 0.25 = 6.25 feet of yarn.

Since Muhammad needs at least 6 feet of yarn to make a scarf, and he has 6.25 feet of yarn, he will be able to make a scarf.

Therefore, the answer is 6 feet.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. Therefore, option B is the correct answer.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. This is because the electron microscope requires a vacuum environment to function properly, which would kill any live specimen. Additionally, electron microscopes can only see surface details and do not have a very high power of resolution. Lastly, electron microscopes can only be used by doctors or trained technicians, so they are not as widely available as light microscopes.

Answer:

y = 8/3(x) + 9

Step-by-step explanation:

The general equation of a straight line is slope intercept form is;

y = mx + b

where m is the slope and b is the y-intercept

To get the slope, we use the slope equation

we have this as:

m = (y2-y1)/(x2-x1)

(x1,y1) = (-6,-7)

(x2,y2) = (-3,1)

m = (1+7)/(-3 + 6) = 8/3

so we have the equation as;

y = 8/3(x) + b

to get the value of b, we make use of any of the two points

We substitute the coordinates of the two points into the equation

Let us use the point (-3,1)

Thus;

1 = 8/3(-3) + b

1 = -8 + b

b = 1 + 8

b = 9

So the full equation is;

y = 8/3(x) + 9

\(\\ \sf\longmapsto \dfrac{3p}{5}+\dfrac{8}{5}=1\)

\(\\ \sf\longmapsto \dfrac{3p+8}{5}=1\)

\(\\ \sf\longmapsto 3p+8=5\)

\(\\ \sf\longmapsto 3p=5-8\)

\(\\ \sf\longmapsto 3p=-3\)

\(\\ \sf\longmapsto p=\dfrac{-3}{3}\)

Answer:  Use a tree diagram for conditional probability

The first branch lists the elements in the starting field-- how many items or outcomes. Like heads or tails, how many of each color of marbles or socks, etc. The next branch shows the set of outcomes from the first event and what is available for the next event. The branches are labeled with fractions to tell the chances of each outcome.

Step-by-step explanation:

A tree diagram is good for determining probability when there are multiple steps in the "draw" and multiple outcomes-- sometimes chances of event a and b "this and that" or event a or b "this or that"

You use the fractions on each branch to calculate the final outcome. If it's a and b, you multiply the fractions on each "trail" you follow through the branches to get the defined final outcome.

If it is a or b, you add the fractions to get the probability of the defined final outcome.

The solutions of the quadratic equation\(-3x^2 + 1 = 3x - 2\) are -1/3 and 1.

To solve this equation, we can use the quadratic formula:

\(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\)

In this case, the coefficients are a = -3, b = 3, and c = -2. Substituting these values into the quadratic formula, we get:

\(x = \dfrac{(-3 \pm \sqrt{3^2 - 4 \cdot -3 \cdot -2})}{2 \cdot -3}\)

\(x = \dfrac{(-3 \pm \sqrt{27 + 24})}{-6}\)

\(x &= \dfrac{(-3 \pm \sqrt{51})}{-6} \\x&= \dfrac{(-3 \pm 3\sqrt{7})}{-6}\)

\(x = -1/3 or 1\)

Therefore, the solutions of the quadratic equation are -1/3 and 1.

Here is a breakdown of the steps involved in solving for the solutions of the quadratic equation:

Answer:A

Step-by-step explanation:

the coefficient of determination is 0.7, indicating that the independent variables explain 70% of the variation in the dependent variable.

The coefficient of determination, also known as R-squared, is a measure of how well the independent variables explain the variation in the dependent variable. It is calculated as the ratio of the explained variation to the total variation.

In this case, SST (total sum of squares) is 800 and SSE (error sum of squares) is 240. Therefore, the explained sum of squares (SSE) is 800 - 240 = 560.

The coefficient of determination is then calculated as:

R-squared = explained variation / total variation

R-squared = 560 / 800

R-squared = 0.7

Therefore, the coefficient of determination is 0.7, indicating that the independent variables explain 70% of the variation in the dependent variable.

When using a one-way within-groups ANOVA, the variability due to individual differences is reduced, resulting in a more accurate assessment of the effect of the independent variable on the dependent variable.

To minimize the variation between individuals, their scores are evaluated within the same group rather than comparing them across different groups.

The within-groups ANOVA method utilizes identical individuals in different conditions or treatments to counteract personal variances, thereby enabling a more accurate measurement of the independent variable's impact.

By adopting this method, the analysis gains greater statistical strength, resulting in a more heightened aptitude to identify genuine effects of the independent factor on the dependent element.

Question:

Let \(p=x^2-2\) .

Which equation is equivalent to in terms of p ?

Answer:

\(p^2+18=9p\) or \(p^2+18 - 9p = 0\)

Step-by-step explanation:

Given

\(p=x^2-2\) .

Required

Find the equation equivalent to \((x^2-2)^2+18=9x^2-18\)

To get the equation equivalent to the given expression, we simply simplify \((x^2-2)^2+18=9x^2-18\) and solve in terms of p

\((x^2-2)^2+18=9x^2-18\)

Factorize expression on the right hand side

\((x^2-2)^2+18=9(x^2-2)\)

Substitute \(x^2 - 2\) for p

\((x^2-2)^2+18=9(x^2-2)\) becomes

\(p^2+18=9p\)

Hence, equation \(p^2+18=9p\) is equivalent to \((x^2-2)^2+18=9x^2-18\)

Solving further to get the value of p

\(p^2+18=9p\)

Subtract 9p from both sides

\(p^2+18 - 9p = 9p - 9p\)

\(p^2+18 - 9p = 0\)

Rearrange

\(p^2 - 9p +18 = 0\)

Factorize

\(p^2 - 6p - 3p +18 = 0\)

\(p(p - 6) - 3(p -6) = 0\)

\((p - 3)(p -6) = 0\)
