The probability of not rolling a 1 when rolling a six-sided die is approximately 83%. This means that if you roll the die many times, you would expect to get a 1 about 1/6 of the time and not get a 1 about 5/6 of the time.

When you roll a six-sided die, there are six possible outcomes, each with equal probability. These outcomes are rolling a 1, 2, 3, 4, 5, or 6. If you want to find the probability of not rolling a 1, you can count the number of outcomes that are not 1 and divide by the total number of outcomes.

Since there are five outcomes that are not 1 (2, 3, 4, 5, and 6) and six total outcomes, the probability of not rolling a 1 is 5/6.

To write this as a percentage rounded to the nearest whole number, we can multiply by 100 and round to the nearest whole number:

5/6 × 100 ≈ 83%.

Answer:

a. The probability that all 5 selected transistors are defective is 0.0024 or 0.24%.

To calculate this probability, we use the formula for the probability of the intersection of independent events:

P(all 5 defective) = P(defective) x P(defective) x P(defective) x P(defective) x P(defective)

where P(defective) = 5/12 for each transistor.

Plugging in the values, we get:

P(all 5 defective) = (5/12) x (5/12) x (5/12) x (5/12) x (5/12) = 0.0024

b. The probability that none of the selected transistors are defective is 0.163 or 16.3%.

To calculate this probability, we use the complement rule:

P(none defective) = 1 - P(at least one defective)

To calculate P(at least one defective), we can use the complement rule again:

P(at least one defective) = 1 - P(none defective)

So, we need to find P(none defective) first:

P(none defective) = P(not defective) x P(not defective) x P(not defective) x P(not defective) x P(not defective)

where P(not defective) = 7/12 for each transistor.

Plugging in the values, we get:

P(none defective) = (7/12) x (7/12) x (7/12) x (7/12) x (7/12) = 0.163

Then, we can find P(at least one defective):

P(at least one defective) = 1 - P(none defective) = 1 - 0.163 = 0.837

Finally, we can find P(none are defective) using the complement rule:

P(none defective) = 1 - P(at least one defective) = 1 - 0.837 = 0.163.

Answer:

X=-√7 and √7

Step-by-step explanation:

To solve the equation 6x² - 42 = 0, we can begin by rearranging it to isolate the variable term:

6x² = 42

Then, we can divide both sides by 6:

x² = 7

To get the exact values of x, we need to take the square root of both sides:

x = ±√7

Therefore, the exact values of x are √7 and -√7.

The value of x when the Richter scale rating is 7.9, rounded to the nearest whole number, is approximately 79,432,823.

The formula relating the Richter scale rating (r) and the intensity ratio (x) is r = log(x). To find the value of x when r is 7.9, we can rearrange the formula and solve for x,

x = 10ʳ

Substituting r=7.9 into the formula, we get,

[tex]x = log((10)^{7.9} )[/tex]

Using a calculator, we get,

x ≈ 79432823.09

Rounding this to the nearest whole number, we get,

(c) the probability of generating a sequence of six identical digits is [tex](1/10)^6[/tex]

(e)  the probability of generating a sequence with exactly one repeated digit is[tex]10 * 6 * (9^4).[/tex]

Probability is described as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Answer:

2 miles = 3,520 yards

Step-by-step explanation:

You multiply the length value by 1,760.

3520 yards is equivalent to 2 miles.

The correct graph of the inequality ( |x| + 3 > 3) is attached accordingly.

Recall that the absolute value (or modulus) of a real number x is its non-negative value regardless of its sign. For example, 5 has an absolute value of 5, and 5 has an absolute value of 5.

A number's absolute value can be conceived of as its distance from zero along the real number line.

So, given  |x| + 3 > 3

Add minus three to both sides

|x| + 3  + (-3) > 3 + (-3)

|x|  > 0

Thus, the absolute value of x is

After considering all the given data we reach  the conclusion that the probability of randomly selecting a point that falls in the red shaded triangle is 0.30.

To evaluate the probability that a randomly selected point within the circle falls in the red shaded triangle, we have  to calculate the ratio of the area of the red shaded triangle to the area of the circle.
Let us consider that the radius of the circle is 4 cm. The area of the circle is
πr² = 3.14 × 5²
= 78.5 cm².
The concerned area of red shaded triangle is
(1/2) ×(3 + 3) × (8)
= 1/2 × 6 × 8
= 24 cm².
Therefore, the probability of randomly placing the point on the red part of the triangle is
P = Area of Triangle / Area of Circle = 24 / 78.5
≈ 0.30

If the flow rate of the tap is reduced to 7 litres per minute, it would take 36 hours to fill the reservoir.

Let's use the formula:

time = volume/flow rate

where volume is the volume of the reservoir and flow rate is the flow rate of the tap.

Let V be the volume of the reservoir.

With a flow of 18 litres per minute, we have:

14 hours = V / 18 L/min

Solving for V, we get:

V = 14 hours x 18 L/min = 252 L

Now, let's find the time it takes to fill the same reservoir with a flow of 7 litres per minute:

time = V / 7 L/min

Substituting V with 252 L, we get:

time = 252 L / 7 L/min = 36 hours

Therefore, it will take 36 hours to fill the reservoir with a flow rate of 7 litres per minute.
