Step-by-step explanation:

The snowfall of both towns by equal in 4/5 hours or 48 minutes.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Assuming the no. of hours to be x, therefore the expression for town 1 is

y = (7/2)x + 5 and the expression for town 2 is y = (9/4)x + 6.

The snowfall of both towns by equal when,

(7/2)x + 5 = (9/4)x + 6.

(7/2)x - (9/4)x = 6 - 5.

[(14 - 9)x]/4 = 1.

(5/4)x = 1.

x = 4/5 hours Or (4/5)×60 = 48 minutes the snowfall of both towns by equal.

Answer:

The money he makes mowing lawn can be represented by a linear function.

The function can be represented in the slope-intercept form.

the equation of the function is y=500+10x

where

y=amount of money he has earned by mowing lawns.

x=number of lawn mowing clients he has.

Step-by-step explanation:

It can be represented by a linear function (straight line) because the additional amounts are proportional to the number of clients he has.

The equation is

y=500+10x

where

y=amount of money he has

x=number of lawn mowing client he has.

Answer: solve for x

x ∈ R, h = 0 and g = 0

Step-by-step explanation:

The  Q(x) has two distinct quadratic factors: (x - i) and (x + i).

Q(x) has single irreducible quadratic factors.

To find Q(2), we substitute x = 2 into the given expression:

Q(2) = (2 - 1)º(2^2 + 1)?(-1) = 1 * 5 * (-1) = -5

Since Q(2) is negative, we know that Q(x) must have at least one irreducible quadratic factor with a negative coefficient (since the constant term is negative).

To determine whether this quadratic factor is repeated or not, we can factor Q(x) using the quadratic formula:

Q(x) = (x - 1)º(x2 + 1)?(-1)

= (x - 1)º[(x - i)(x + i)]?(-1)

= (x - 1)º(x - i)?(x + i)?(-1)

This shows that Q(x) has two distinct quadratic factors: (x - i) and (x + i). Therefore, Q(x) has single irreducible quadratic factors.

Answer:

The number is 24

Step-by-step explanation:

The quotient is the answer of a division problem. If a number is divided by 3 and the answer is 8, then the number would be 24. You could set it up into an  equation.

x/3=8

then you multiply both sides by 3 and you will get

x=24

The quotient is indeed the number generated by dividing one integer by the other. Whenever a fraction is simplified, the division is the whole amount that results.

Calculation of the equation:

\(\to \bold{\frac{x}{3}=8}\\\\\to \bold{x=8\times 3} \\\\\to \bold{x=24}\)

Therefore, the final answer is "24".

The slope intercept form of equation of line is given by

y = 3x + 4

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If \(\theta\)  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m =  \(tan \theta\)

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The given line is y = 3x - 8

Slope = 3

Slope of the line parallel to this line = 3

The line passes through the point (-2, -2)

Required equation of line

y - (-2) = 3(x - (-2))

y+2 = 3(x +2)

y+2 = 3x + 6

Step-by-step explanation:

Given expression,

→ 4 + 5(2x - 3) - 6x

Let's simplify the expression,

→ 4 + 5(2x - 3) - 6x

→ 4 + 10x - 15 - 6x

→ (10x - 6x) + (4 - 15)

→ (4x) + (-11)

→ 4x - 11

Hence, the answer is 4x - 11.

The canonical expression equivalent to sinusoidal model y(t) = 2 · sin (4π · t) + 5 · cos (4π · t) is y(t) = (√ 29) · sin (4π · t + 0.379π) .

Herein we have a simple harmonic motion model represented by a sinusoidal expression of the form y(t) = A · sin (C · t) + B · cos (C · t), which must be transformed into its canonical form, that is, y(t) = A' · sin (C · t + D). We proceed to perform the procedure by algebraic and trigonometric handling.

The amplitude of the canonical function is determined by the Pythagorean theorem:

A' = √(2² + 5²)

A' = √ 29

The angular frequency C  is the constant within the trigonometric functions from the non-canonical formula:

C = 4π

Then, we find the initial position of the weight in time: (t = 0)

y(0) = 2 · sin (4π · 0) + 5 · cos (4π · 0)

y(0) = 5

And now we calculate the angular phase below: (A' = √ 29, C = 4π, y = 5)

5 = √ 29 · sin (4π · 0 + D)

5 / √ 29 = sin D

D ≈ 0.379π rad

The canonical expression equivalent to sinusoidal model y(t) = 2 · sin (4π · t) + 5 · cos (4π · t) is y(t) = (√ 29) · sin (4π · t + 0.379π) .

Answer:

Step-by-step explanation:

taking - common

- (5x + 7) >= 17

you must have heard that the direction of inequality gets inverted when the signs of equations on both sides is inverted.

so,

5x + 7 <= - 17

5x + 7 - 7 <= -17 - 7

5x <= - 24

x <= -24/ 5

so, the value of x can be less than or equal to -24/ 5

upon solving -24/5 we get -4.8

and the question is asking for largest integral value, then it will be - 5

check the number line for this

-6 -5 -4.8 -4 -3 -2 ....

suppose this is a number line.

the value of x lies on the left side of -4.8 and -4.8 is not an integer so we'll skip onto -5 which is the following integer on the required side.

so the answer is -5

Null space is defined as the set of vectors 'x' in Rn that are solutions to the matrix equation A*x = 0. False: The set of all vectors of the form 1 x y where x and y range over all real numbers is a subspace of R3. True: The set of all vectors of the form 0 x y where x and y range over all real numbers is not a subspace of R3.

1) False Null space can consist of zero vector only. A null space is defined as the set of vectors 'x' in R^n that are solutions to the matrix equation A*x = 0.

2) True The number of columns can never be less than the number of rows of the matrix in order for a null space to exist, hence a 4x3 matrix may have the null space of only the zero vector.

3) True The set of all vectors of the form 1 x y where x and y range over all real numbers, is a subspace of R^3. This set contains zero vector because for x=0 and y=0, we get the vector as [0,0,0]. Hence it is a subspace of R^3.

4) False The set of all vectors of the form 0 x y where x and y range over all real numbers, is not a subspace of R^3 as it doesn't contain zero vector. To have a subspace of R^3, it should contain a zero vector.

Using the z table, the critical value \(z_{a/2}\) needed to construct a confidence interval with level 82% is 1.34.

In the given question,

We have to find the critical value \(z_{a/2}\) needed to construct a confidence interval with level 82%.

The confidence interval is 82%.

We can write 82% as 82/100 and 0.82.

Now the value of

\(\alpha\)=1−0.82

\(\alpha\)=0.18

Now finding the value of \(\alpha\)/2

\(\alpha\)/2=0.18/2

\(\alpha\)/2=0.09

Now finding the value of \(z_{a/2}\).

\(z_{0.82}\) = 1.34

Hence, the critical value \(z_{a/2}\) needed to construct a confidence interval with level 82% is 1.34.

(-2, 1) and (3, -2)

Parallel lines have the same slope. Thus, we have to find ordered pairs with a slope of -3/5.

We have:

slope of the line is -3/5.

Thus, m = -3/5

Formula for slope between two coordinates is;

m = (y₂ - y₁)/(x₂ - x₁)

A) At (–8, 8) and (2, 2);

m = (2 - 8)/(2 - (-8))

m = -6/10

m = -3/5

m = (2 - (-1))/(0 - (-5))

m = 3/5

C) At (–3, 6) and (6, –9);

m = (-9 - 6)/(6 - (-3))

m = -15/9

m = -5/3

D) At (–2, 1) and (3, –2);

The mean, median, mode, range, variance, standard deviation, 65th percentile, interquartile range, coefficient of variation and Z-score for a usage time of 4.5 hours. Mean Mean of the data set is the sum of the data values divided by the total number of data values. It is shown by: Mean = (3.8 + 7.3 + 3.5 + 3.0 + 4.5 + 4.6)/6 = 26.7/6 = 4.45 hours Median Median of the data set is the middle value of the data when it is arranged in ascending or descending order. If the data set has an odd number of values, then the median is the middle value. If the data set has an even number of values, then the median is the average of the two middle values. Here the data set has an even number of values, so we take the average of the middle two values. Median = (3.8 + 4.5)/2 = 4.15 hours Mode Mode of the data set is the value that occurs most frequently in the data set. Here there is no value that occurs more than once, so the data set has no mode.

Here the data set has 6 values, so the 65th percentile is the 0.65 * 6 = 3.9th value. When we arrange the data in ascending order, the 3.9th value is between the 4th and 5th values. So we take the average of these two values.65th percentile = (3.5 + 4.5)/2 = 4 hours Interquartile range The interquartile range is the difference between the third quartile and the first quartile. The first quartile (Q1) is the median of the data values less than the median. The third quartile (Q3) is the median of the data values greater than the median.

The probability of the first two songs played being slow songs is approximately 0.5454.

The probability that the first two songs played are slow songs can be calculated by dividing the number of favorable outcomes (two slow songs) by the total number of possible outcomes.

Since there are 9 slow songs out of 12 total songs, the probability of selecting a slow song as the first song is 9/12. After the first slow song is played, there are 8 slow songs left out of the remaining 11 songs. Therefore, the probability of selecting a slow song as the second song, given that the first song was slow, is 8/11.

To find the probability of both events occurring (selecting a slow song first and then selecting a slow song second), we multiply the probabilities of each event:

P(First song slow) * P(Second song slow | First song slow) = (9/12) * (8/11) = 72/132 = 0.5454 (rounded to four decimal places).

The probability that the first two songs played are slow songs is 0.5454.
