The length of each Plan A workout will be 1.25 hours and the length of each Plan B workout will be 1.25 hours.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Let 'x' be the number of hours of plan A and 'y' be the number of hours of plan B. Then the equations are given as,

2x + 6y = 10

x + 3y = 5            ...1

5x + 3y = 10        ...2

Subtract equation 1 from equation 2, then we have

5x - x = 10 - 5

4x = 5

x = 1.25 hours

Then the value of 'y' is calculated as,

1.25 + 3y = 5

3y = 3.75

y = 1.25

The 95% confidence interval for difference in mean drying times of two type of paints is (4.90, 17.50). This suggests that Type A takes between 4.90 and 17.50 hours more to dry than type B paint.

Given that,

A paint's formula was altered by the manufacturer to hasten drying time. 11 cans of type A (the original paint) and 9 cans of type B (the modified paint) were randomly chosen at random and applied on comparable surfaces. The drying periods were measured in hours. The following are the statistics in brief.

Type A                 Type B

Sample-1             Sample-2

x₁ = 76.3 hrs        x₂ = 65.1 hrs

s₁ = 4.5 hrs          s₂ = 5.1 hrs

n₁ = 11                   n₂ = 9

We have to create a 98% confidence interval for the range 1–2, which represents the difference in the average drying time for paint cans of types A and B.

We know that,

Consider about Type A, which is the original paint, and Type B, which is the changed paint.

The difference between the mean drying time for paint cans of type A and the mean drying time for paint cans of type is within a 98% confidence interval, and it is as follows:

4.90 < μ₁ - μ₂ < 17.50

Therefore, The 95% confidence interval for difference in mean drying times of two type of paints is (4.90, 17.50). This suggests that Type A takes between 4.90 and 17.50 hours more to dry than type B paint.

Answer:

To solve the absolute value inequality 4x+7

3

< 8, we need to first isolate the absolute value expression on one side of the inequality. We can do this by dividing both sides of the inequality by 3, which gives us 4x+7<24.

Next, we need to consider two cases, depending on whether the quantity inside the absolute value is positive or negative. If the quantity inside the absolute value is positive, then the inequality will remain unchanged. In this case, we have 4x+7<24, which we can solve by subtracting 7 from both sides to get 4x<17, and then dividing both sides by 4 to get x<4.25.

If the quantity inside the absolute value is negative, then the inequality will be reversed. In this case, we have 4x+7>24, which we can solve by subtracting 7 from both sides to get 4x>17, and then dividing both sides by 4 to get x>4.25.

Therefore, the solution to the inequality 4x+7

3

< 8 is the set of all values of x that are less than 4.25 or greater than 4.25. We can write this solution in interval notation as (-∞,4.25)∪(4.25,∞), or as a union of two disjoint intervals: (-∞,4.25) and (4.25,∞).

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

You have $1000 to put resources into two distinct records. To set aside the cash you really want for school, you really want to average a 6.1 percent premium. Assuming the two records pay a 3% and 7 % premium.

Let 'x' be the amount deposited in an account that pays 3% of interest. Then the amount deposited in another account that pays 7% of interest is (1000 - x). Then the equation is given as,

0.03x + 0.07(1000 - x) = 0.061 × 1000

Simplify the equation, then we have

0.03x + 0.07(1000 - x) = 0.061 × 1000

0.03x + 70 - 0.07x = 61

-0.04x + 70 = 61

0.04x = 70 - 61

0.04x = 9

x = 9 / 0.04

x = $225

Then the amount in the second account will be given as,

⇒ $1000 - $225

Step-by-step explanation:

In the equation:

the " +6 " in close to the x represents the horizontal shift. X always tells us about horizontal or right/left moves. So an adjustment to the x is a horizontal adjustment.

But Caution! It is the opposite of what you might think. A PLUS6 is a LEFT shift. (While a MINUS6 would be a right shift, not the case here).

The four types of probability sampling methods are

1. Simple random sampling

2. Stratified sampling

3. Systematic sampling

4. Cluster sampling

Probability sampling is a sampling method that involves randomly selecting a sample, or a part of the population that you want to research.

1. Simple Random Sampling: Simple random sampling gathers a random selection from the entire population, where each unit has an equal chance of selection. This is the most common way to select a random sample.

2. Stratified Sampling: Stratified sampling collects a random selection of a sample from within certain strata, or subgroups within the population. Each subgroup is separated from the others on the basis of a common characteristic.

3. Systematic Sampling: Systematic sampling draws a random sample from the target population by selecting units at regular intervals starting from a random point. This method is useful in situations where records of target population already exist.

4. Cluster Sampling: Cluster sampling is the process of dividing the target population into groups, called clusters. A randomly selected subsection of these groups then forms the sample. It usually involves existing groups that are similar to each other in some way

The probability of a coin landing on heads 4 times in a row is 1/16 or, 6.25%, the probability of flipping a coin and it landing heads is 1/2 or, 50%, the probability that exactly four students toss heads at least 4 times each is 1/16 or, 6.25%, and the probability of getting heads both times the coin is flipped is 0.25.

There are different situations for us stated as -

(a) What is the probability of a coin landing on heads 4 times in a row?

(b) What is the probability of flipping a coin and it landing heads?

(c) What is the probability that exactly four students toss heads at least 4 times each?

(d)What is the probability of flipping a coin and getting heads both times?

We have to find out the probability of the given situations happening.

(a) It is known to us that a coin is flipped.

We have to determine the probability of this coin landing on heads 4 times in a row.

In order to get 4 heads in a row, the coin should be flipped 4 times.

For n (say) number of heads, the value of n = 0, 1, 2, 3, 4

Total number of possible outcomes = 16

It can be concluded that there is only one possible outcome that will result in the coin landing on 4 heads where each flip ends up as a head.

So, the probability = 1/16

Thus, the probability of a coin landing on heads 4 times in a row is 1/16 or, 6.25%.

(b) It is known to us that a coin is flipped.

We have to find out the probability of this flipped coin landing on heads.

When a coin is flipped in the air, there is always 50% chance of the coin landing on heads and a 50% chance of the coin landing on tails.

So, the probability = 1/2

Thus, the probability of flipping a coin and it landing heads is 1/2 or, 50%.

(c) It is known to us that exactly four students toss coins.

We have to determine the probability that exactly four students toss heads at least 4 times each.

As mentioned in the previous part of the question, there is always 50% chance of the coin landing on heads.

So, the probability of getting heads when the coin is flipped first = 1/2

=> the probability of getting two heads in a row = 1/2 * 1/2 = 1/4

=> the probability of getting three heads in a row = 1/2 * 1/4 = 1/8

=> the probability of getting four heads in a row = 1/2 * 1/8 = 1/16

Thus, the probability that exactly four students toss heads at least 4 times each is 1/16 or, 6.25%.

(d) It is known to us that a coin is flipped.

We have to find out the probability of getting heads both times.

Since, there is always 50% chance of the coin landing on heads. So, the probability of getting heads both times = 0.5 * 0.5 = 0.25

Thus, the probability of getting heads both times the coin is flipped is 0.25.

Therefore, the probability of a coin landing on heads 4 times in a row is 1/16 or, 6.25%, the probability of flipping a coin and it landing heads is 1/2 or, 50%, the probability that exactly four students toss heads at least 4 times each is 1/16 or, 6.25%, and the probability of getting heads both times the coin is flipped is 0.25.
