The value from the set {10, 11, 12, 13} that makes the equation 2(x − 5) = 12 true is
.​

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

In a case whereby farmer harvested 250 bags of maize in a season. If he sold 200 bags, the percentage of his crops does this represent is 80%.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

harvested =250 bags

sold =200 bags

percentage of his crops  = 200/250 *100%

A fresh analysis published by the UK Health Security Agency suggests the Omicron variant will be responsible for at least 50% of Covid cases within two to four weeks.

The prediction is based on the number of cases judged to be suspected Omicron from testing data.

That shows around 2% of daily cases are being caused by the new variant. If that is correct it would mean there are about 1,000 Omicron cases every 24 hours.

What is more, the cases are thought to be doubling every two or three days.

What is not yet known is whether Omicron will completely replace Delta, the variant that is currently dominant.

Answer:

\(2\frac{1}{6}\ hours\)

Step-by-step explanation:

Given

\(Session\ 1: 1\frac{1}{6}\)

\(Session\ 2: 2\frac{1}{2}\)

\(Session\ 3: \frac{2}{3}\)

\(Total\ Time = 6\frac{1}{2}\)

Required

Determine the time in the last session

Represent the 4th session with x

So, we have:

\(Session\ 1 + Session\ 2 + Session\ 3 + x = Total\ Time\)

Substitute values for Session 1-3 and Total Time

\(1\frac{1}{6} + 2\frac{1}{2} + \frac{2}{3} + x = 6\frac{1}{2}\)

Collect Like Terms

\(x = 6\frac{1}{2} - 1\frac{1}{6} - 2\frac{1}{2} - \frac{2}{3}\)

Convert to improper fractions

\(x = \frac{13}{2} - \frac{7}{6} - \frac{5}{2} - \frac{2}{3}\)

Take LCM

\(x = \frac{39 - 7 - 15 - 4}{6}\)

\(x = \frac{13}{6}\)

Convert to improper fraction

\(x = 2\frac{1}{6}\)

Hence, the time left is \(2\frac{1}{6}\ hours\)

For a dilation with a scale factor not equal to one, the angles and side lengths of the preimage relate to the angles and side lengths of the image because: B. Angles are congruent, side lengths are proportional.

In Geometry, dilation is a type of transformation which changes the size of a geometric figure and the location of its points based on the scale factor, but not its shape.

In Geometry, a scale factor can be defined as the ratio of two corresponding side lengths or diameter in two similar geometric figures (shapes) such as equilateral triangles, square, quadrilaterals, polygons, etc., which can be used to either enlarge or reduce their size.

Generally speaking, the angles and side lengths of the preimage and image are congruent and proportional when the dilation of any geometric figure with a scale factor that is not equal to one (1).

Answer:

A reduction with scale factor of 1/4

Explanation:

Since S'T'U'V' is smaller than STUV, the dilation is called reduction.

Then, the scale factor is calculated as

Scale factor = Length of image/ Length of original

So, using the segment ST, we get

Length of image = Length of S'T' = 1

Length of original = Length of ST = 4

Then

Scale factor = 1/4

Therefore, the answer is

a reduction with scale factor of 1/4
