To hide the last two rows in a table view in Swift and set their row heights to 0, you can modify the table view's delegate method `heightForRowAt` for the respective rows.

In Swift, you can achieve this by implementing the UITableViewDelegate protocol's method `heightForRowAt`. Inside this method, you can check if the indexPath corresponds to the last two rows (in this case, rows 9 and 10). If it does, you can return a row height of 0 to hide them from the view. Here's an example of how you can write this logic:

```swift

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

   let numberOfRows = tableView.numberOfRows(inSection: indexPath.section)

   if indexPath.row == numberOfRows - 2 || indexPath.row == numberOfRows - 1 {

       return 0

   }

   return UITableView.automaticDimension

}

```

In the above code, `tableView(_:heightForRowAt:)` is the delegate method that returns the height of each row. We use the `numberOfRows(inSection:)` method to get the total number of rows in the table view's section. If the current `indexPath.row` is equal to `numberOfRows - 2` or `numberOfRows - 1`, we return a height of 0 to hide those rows. Otherwise, we return `UITableView.automaticDimension` to maintain the default row height for other rows.

By implementing this logic in the `heightForRowAt` method, the last two rows in the table view will be effectively hidden from the view by setting their row heights to 0.

Step-by-step explanation:

Based on the concept of conditional probability, the probability that the first iPod is defective and the others are not defective is approximately 0.1842

Conditional Probability is a term that is used to describe the chances that some outcome occurs given that another event has also occurred.

Generally, the functional probability is often stated as the probability of B given A and is written as P(B|A), where the probability of B depends on that of A happening

In this case, to find the answer we break down the problem step by step:

Step 1: Find the probability that the first iPod is defective.

Since there are 3 defective iPods out of 20 total the probability of selecting a defective iPod on the first draw is 3/20.

Step 2: Find the probability that the second and third iPods are not defective.

After selecting a defective iPod there are 19 remaining iPods in the box out of which 17 are not defective.

Hence, the probability of selecting a non-defective iPod on the second draw is 17/19.

Also, given that the probability of selecting a non-defective iPod on the third draw (assuming the previous two iPods were not defective) is 16/18.

Step 3: Finding the overall probability.

The overall probability of the first iPod being defective and the second and third iPods being non-defective can be computed by multiplying the probabilities of each step:

Probability = (3/20) * (17/19) * (16/18)

= (51/380) * (16/18)

= 0.1842105

Therefore, in this case, it is concluded that the correct answer is approximately 0.1842 or 18.42%.

Using a system of equations, the cost per apple would be $1.80

Let the amount he has now = p

Cost per apple = a

15a = 2.10 + p - - - (1)

12a = p - 3.30 - - - (2)

From (1) :

p = 15a - 2.10 - - - - (3)

Substitute (3) into (2)

12a = 15a - 2.10 - 3.30

Collect like terms

12a - 15a = - 3.30 - 2.10

-3a = - 5.40

Divide both sides by - 3

a = $1.80

The probability that Mrs. Barnes does not check homework if the students take a pop quiz will be 0.77. Then the correct option is D.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Mrs. Barnes’s class determined the probability that she will check homework on a randomly chosen day is 0.42.

They also determined the probability that she will give a pop quiz when she checks homework is 0.6, and the probability that she will give a pop quiz when she does not check homework is 0.9.

Then the probability that Mrs. Barnes does not check homework if the students take a pop quiz will be

\(\rm P = 0.42 \times 0.60 + 0.58\times 0.90\\\\P = 0.252 + 0.522\\\\P = 0.774 \approx 0.77\)

The length of a side of the square is 8 cm.

What do you mean by perimeter of a rectangle and square?

When a wire is bent into the shape of a rectangle, its length becomes the perimeter of the rectangle. Similarly, when the wire is reshaped into a square, its length becomes the perimeter of the square.

The perimeter of a rectangle is given by the formula \(P=2(l+w)\) , where \(l\) is the length and \(w\) is the width.

The perimeter of a square is given by the formula \(P=4s\) , where \(s\) is the length of a side.

Calculating the length of a side of the square:

The length of the rectangle is 11 cm and the width is 5 cm.

Therefore, the perimeter of the rectangle is \(P=2(11+5)=32\) cm.

Since the wire is reshaped into a square, the perimeter of the square is also 32 cm.

Using the formula \(P=4s\), we can solve for the length of a side of the square:

\(32 = 4s\)

\(s = 32/4\)

\(s = 8\)

Therefore, the length of a side of the square is 8 cm.

Answer:

Hanna

Step-by-step explanation:

In order to find out how fast Thomas has drove as compared to Hanma we have to compare the speed of each other,

Speed of Hanna = 50mph (as given in ur question)

Speed of Thomas

Since the unit of time of the distance traveled by Thomas is not same as that of Hanna we have to convert the minutes into hour,

Distance traveled = 12miles

Time taken = 15minutes

Speed = 12miles/15mim

Converting minutes into hours we have to multiply by a number whose product will be 60 and that will 4

that is 15 times 4 is 60. But to make the ratio equal

we have to multiply the distance too by 4.

= 12*4/15*4

=48 miles/60minutes

=48miles/1hour

=48mph

Comparing both speeds

Speed of Hanna compared to Speed of Thomas,

50mph > 48mph

Hence, Hanna has the faster speed.

How do uv-induced dna lesions lead to mutation? drag the terms on the left to the appropriate blanks on the right to complete the sentences. not all terms will be used.

Answer:

When cells enter S phase with Ultraviolet-induced DNA lesions, the replicative DNA polymerases stall at the lesion.

Step-by-step explanation:

As a result of photosensitization, which causes the production of a free radical that interacts with DNA and oxidizes its bases, ultraviolet radiation causes oxygen-dependent DNA damage. Mutations occur when these oxidized bases don't pair properly during the replication process. The various types of DNA damage caused by ultraviolet radiation result in particular types of mutations and the development of skin cancer in people, frequently decades after initial exposure. There are noticeable UV-induced DNA lesions that are caused by various UV wavelengths.
