Is -10 a rational number?

No -10 is not a rational number, because A rational number is, as the name implies, any number that can be expressed as a ratio, or fraction. The number 6 is rational number because it can be expressed as 6/1, though this would be unusual. 4.5 is a rational number, as it can be represented as 9/2.

sadly it doesnt allow me to add in a photo but ill tell you a good enough explanation of what to draw, for y=3x+2 your line starts at 2 on the y axis and goes down (-3/1)

for y=3x-4 your line starts at -4 and go up by 3/1

Step-by-step explanation:

The probability that a randomly selected cup of hot chocolate would have a temperature of less than 166 degrees is approximately 0.0726, or 7.26%. This would not warrant a replacement cup as it is not considered unusual or significantly deviant from the mean.

- To obtain the probability that a randomly selected cup of hot chocolate would have a temperature of less than 166 degrees, we can use the Z-score and the standard normal distribution.

First, let's calculate the Z-score for the temperature of 166 degrees using the formula:

Z = (X - μ) / σ

where X is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

Z = (166 - 175) / 6.2

Z = -1.4516

Next, we can use a Z-table or a statistical software to find the probability associated with the Z-score of -1.4516.

Looking up the Z-score in the table, we find that the probability is approximately 0.0726.

- To determine whether this outcome is unusual or warrants a replacement cup, we can consider the significance level or the threshold for unusualness.

Commonly, a significance level of 5% (0.05) is used. If the probability of an outcome falls below this threshold, it can be considered unusual.

In this case, the probability of less than 166 degrees is 0.0726, which is greater than 0.05. Therefore, this outcome would not be considered unusual at a significance level of 5%.

It means that a cup of hot chocolate with a temperature below 166 degrees is within the expected range of temperatures based on the given mean and standard deviation and hence, it would not warrant a replacement cup.

To calculate the number of four-card hands chosen from a standard 52-card deck that contain two cards of one suit and two cards of another suit, we need to consider the following:

1. Selecting the suits: There are 4 suits in a deck (hearts, diamonds, clubs, and spades). We need to choose two suits out of these four.

2. Selecting the two cards of one suit: Once we have chosen the two suits, we need to select two cards from one of the chosen suits. There are 13 cards in each suit, so we can choose 2 cards from the 13 available.

3. Selecting the two cards of another suit: After selecting the first suit, we need to choose two cards from the remaining suit. Again, there are 13 cards to choose from.

To calculate the total number of four-card hands satisfying these conditions, we multiply the number of choices at each step. Therefore, the total number of such hands is:

4C2 * 13C2 * 13C2 = (4! / (2! * 2!)) * (13! / (2! * 11!)) * (13! / (2! * 11!))

= 6 * (13 * 12 / (2 * 1)) * (13 * 12 / (2 * 1))

= 6 * 78 * 78

= 36,432.

Therefore, there are 36,432 four-card hands chosen from a standard 52-card deck that contain two cards of one suit and two cards of another suit.

The addition equation to represent Jackson's net change in money is x + (-y) = 4.63

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Jackson receives 4.63 as his change at the grocery store. He places it into a charity donation jar at the register.

WE need to Write an addition equation to represent Jackson's net change in money.

Given that :

The change received = 4.63

The Net change in money :

Let initial amount before purchase is represented by  x

The Cost of item purchased = y (negative as it is incurred)

The Net change in money:

Initial amount + cost of item purchased = change received

x + (-y) = 4.63

Therefore, an addition equation to represent Jackson's net change in money is x + (-y) = 4.63

Answer: The graph of f(x) = x^2 will have only one x-intercept (0,0) since it is a parabola that opens upward and its vertex is at the origin. On the other hand, the graph of g(x) = x^2 +1 is a transformation of the parent function, the graph of f(x) = x^2, where the function was shifted up by 1 unit. Therefore this function g(x) = x^2 +1 will not have any x-intercept because when x=0 the y value becomes 1 so the x-intercept will not be on the x-y plane.

In summary, the graph of f(x) = x^2 has one x-intercept, while the graph of g(x) = x^2 +1 has no x-intercepts due to the transformation of the parent function.

Perimeter of Rectangle is 44m

A perimeter is a closed path that encompasses, encircles, or delineates a one-dimensional length or a two-dimensional shape.

According to the given information

Area of Rectangle = l × b

Area of Rectangle = 105 \(m^{2}\)

Length of one side = 7 m

Let the length of the adjacent side = b

Area of Rectangle given = 7 × b

                     105   = 7 × b

                       b    =  \(\frac{105}{7}\)

                       b   = 15 m

Perimeter of Rectangle given = 2( l + b )

                                        = 2 ( 7 + 15 )

                                        = 2 × 22

                                        = 44m

Perimeter of Rectangle is 44m

The true statements of the angles of the parallel lines are

a) m∠1 = m∠8

b) m∠6 = m∠7

c) m∠4 + m∠6 = 180°

d) 180° - m∠7 = m∠9 + m∠10

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Given data ,

The true statements are

a) m∠1 = m∠8 ( alternate exterior angles )

b) m∠6 = m∠7 ( vertically opposite angles )

c) m∠4 + m∠6 = 180° ( co-interior angles are supplementary )

d) 180° - m∠7 = m∠9 + m∠10 ( triangle exterior angle theorem )

Hence , the angles of the parallel lines are solved

Answer:

B. RZ =R BZ

Step-by-step explanation:

Since point Z is equidistant from the sides of ARST, it lies on the perpendicular bisectors of both sides. Therefore, CZ and SZ are perpendicular bisectors of AB and ST, respectively.

Option B is true because point R lies on the perpendicular bisector of AB, and therefore RZ = RB.

Answer: vv

Step-by-step explanation:

Since point Z is equidistant from the sides of ARST, it lies on the perpendicular bisector of the sides ST and AR.

Therefore, we can draw perpendiculars from point Z to the sides ST and AR, which intersect them at points T' and R', respectively.

Now, let's examine the options:

A. SZ & TZ: This is not necessarily true, as we do not know the exact location of point Z. It could lie anywhere on the perpendicular bisector of ST, and the distance from Z to S and T could be different.

B. RZ = RB: This is true, as point Z lies on the perpendicular bisector of AR, and is therefore equidistant from R and B.

C. CTZ = ASZ: This is not necessarily true, as we do not know the exact location of point Z. It could lie anywhere on the perpendicular bisector of AR, and the distances from Z to C and A could be different.

D. ASZ = ZSB: This is not necessarily true, as we do not know the exact location of point Z. It could lie anywhere on the perpendicular bisector of ST, and the distances from Z to A and B could be different.

Therefore, the only statement that must be true is option B: RZ = RB.
