The probability that among the first two songs played, exactly 1 of the 4 songs you like is played is 0.452 or 45.2%.

Probability is a measure of the likelihood of an event occurring. It is a numerical value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

There are 4 songs that you like out of the 14 total songs, so the probability of selecting a song that you like on the first draw is 4/14.

On the second draw, the probability of selecting a song that you like is 3/13, since there are now 3 songs that you like out of the remaining 13 songs.

The probability of selecting exactly 1 of the 4 songs you like in the first two draws is given by:

P(exactly 1 like in first two draws) = (4/14) ×(10/13) + (10/14) × (4/13) = 0.452

Therefore, the probability that among the first two songs played, exactly 1 of the 4 songs you like is played is approximately 0.452 or 45.2%.

The domain and range of the graph above in interval notation include the following:

Domain = [-6, 3]

Range = [-3, 3]

In Mathematics and Geometry, a domain refers to the set of all real numbers (x-values) for which a particular function (equation) is defined.

In Mathematics and Geometry, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain and range:

Domain = [-6, 3] or -6 ≤ x < 3.

Range = [-3, 3] or -3 < y < 3

The Division of the sum of (7/8), (15/4), and (1/12) by their multiplication is (2712/168).

To find the division of the sum of (7/8), (15/4), and (1/12) by their multiplication, we first need to calculate the sum and multiplication of the given fractions.

The sum of the fractions is:

(7/8) + (15/4) + (1/12)

To add these fractions, we need a common denominator. The least common multiple of 8, 4, and 12 is 24. Let's convert each fraction to have a denominator of 24:

(7/8) = (21/24)

(15/4) = (90/24)

(1/12) = (2/24)

Now we can add the fractions:

(21/24) + (90/24) + (2/24) = (113/24)

The multiplication of the fractions is:

(7/8) * (15/4) * (1/12)

To multiply fractions, we multiply the numerators and denominators:

(7*15*1) / (8*4*12) = (7/96)

Now we can divide the sum of the fractions by their multiplication:

(113/24) / (7/96)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

(113/24) * (96/7) = (2712/168)

Therefore, the division of the sum of (7/8), (15/4), and (1/12) by their multiplication is (2712/168).

Answer:

1 m 64 cm = 5 ft 4.6 inches

Step-by-step explanation:

Answer:

\(1\ inch = 2\ feet\)

Step-by-step explanation:

Given:

\(Real\ tank\ measurement\ = 24\ feet\)

\(Scale\ measurement\ = 12\ inches\)

Required:

Scale Ratio.

To get the scale ratio, we simply divide the actual measurement by the scale measurement

This is done as follows:

\(Scale\ Ratio = \frac{Actual\ Measurement}{Scale\ Measurement}\)

\(Scale\ Ratio\ = \frac{24\ feet}{12\ inches}\)

[Divide numerator and denominator by 12]

\(Scale\ Ratio\ = \frac{2\ feet}{1\ inch}\)

[Convert the above expression to ratio]

\(Scale\ Ratio = 2\ feet : 1\ inch\)

The interpretation of this is that 1 inch on the scale measurement represent 2 feet on the actual measurements

Answer:

about 7 pretzels

7.5 pretzels

Step-by-step explanation:

24 pretzels / 16 ounces = x / 5 oz

solve for x:

x = 5 oz * (24 pretzels / 16 oz)

oz cancels  

x = 7.5 pretzels

7.5 pretzels, or roughly 7 pretzels

The ratio of the areas of two similar polygons can be found by using the ratio of their perimeters or the ratio of similarity and squaring it which is true.

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

Similar polygons are those whose perimeter ratios are identical to their respective scale factors. The common fraction of the sizes of two matching sides of two identical polygons is known as a scale factor.

The given statement is true.

∵ 0.5(8.4 - 1.6)

We have a number multiplied by the difference of two other numbers, then to solve we need to multiply the number by each number in the bracket

∴ 0.5(8.4 - 1.6) = 0.5(8.4) - 0.5(1.6)

That means we distribute the numbers in the brackets

Then the property is distributive

Answer D

We can show that every proper subspace U of \($\mathbb{R}^2$\) is a line through the origin, as desired.

Let U be a proper subspace of \($ \mathbb{R}^ 2 $\), which means U is a subset of \($ \mathbb{R}^ 2 $\) that is closed under vector addition and scalar multiplication, but does not equal \($ \mathbb{R}^ 2 $\) itself. We need to show that U is a line through the origin.

Given a nonzero vector d in U, we define L = Rd as the line with direction vector d. Since d is nonzero, L is not degenerate and passes through the origin (0,0) since Rd always contains the zero vector (0,0).

Now, let u be a vector in U but not in L. Since u is in U, and U is a subspace, u must be closed under scalar multiplication. Thus, for any scalar r in \($ \mathbb{R} $\), \(r_u\) must also be in U.

Consider any vector v in \($ \mathbb{R}^ 2 $\). We want to show that v can be expressed as a linear combination of u and d.

Since u is not in L, u and d must be linearly independent, as any nonzero vector on the line L = Rd is a scalar multiple of d. This means that u and d do not lie on the same line through the origin.

Geometrically, this implies that u and d span the entire plane \($ \mathbb{R}^ 2 $\), as they do not lie on the same line and any vector in \($ \mathbb{R}^ 2 $\) can be expressed as a linear combination of u and d.

Thus, for any vector v in \($ \mathbb{R}^ 2 $\), v can be expressed as a linear combination of u and d.

Specifically, we can write \(v = c_1u + c_2d\), where \(c_1\) and \(c_2\) are scalars.

Since U is closed under scalar multiplication, \(c_1u\) and \(c_2d\) must also be in U for any scalar \(c_1\) and \(c_2\). Therefore, U contains all possible linear combinations of u and d, and U must be a subspace that spans the entire plane \($ \mathbb{R}^ 2 $\).

However, since U is a proper subspace, it cannot span the entire plane \($ \mathbb{R}^ 2 $\). The only way for U to span the entire plane \($ \mathbb{R}^ 2 $\) while still being a proper subspace is if U is a line through the origin.
