The equation of the line with slope 1/3 and y-intercept as -1 is y = x/3-1 in slope-intercept form.

According to the question,

We have the following information:

Slope of the line = 1/3

We know that the slope of the line is denoted by m.

y-intercept of the line = -1

We know that the y-intercept is denoted by b.

We have the following equation for the line in slope-intercept form:

y = mx+b

Putting the above values in this equation:

y = x/3-1

Answer:

Step-by-step explanation:

A coefficient is a number  (integer) which is multiplied with an unknown value (the variable of a single term or the terms of a polynomial).

In this case , n is the variable of a single term and 3 is the coefficient.

Answer: The equations that represent circles that have a diameter of 12 units and a center that lies on the y-axis are:

(x – 6)² + y² = 36

x2 + (y + 6)² = 36

Because a diameter is the distance between two points on a circle that is farthest from each other, the radius of the process must be half of the diameter. So the radius of the ring is 6 units.

The center of the circle must be on the y-axis, it means that the x coordinate of the center is 0, so the equation of the circle will be (x - h)² + (y - k)² = r² where h = 0, k = center on the y-axis, and r = 6.

The first equation, x2 + (y – 3)2 = 36, doesn't represent a circle with a center on the y-axis, because the center of the circle is represented by (0, 3) which is not on the y-axis.

The second equation x2 + (y – 5)2 = 6 doesn't represent a circle with a diameter of 12 units, because the value of the equation is 6 which is not equal to the square of the radius.

The third equation, (x – 4)² + y² = 36, doesn't represent a circle with a center on the y-axis, because the center of the circle is represented by (4, 0) which is not on the y-axis.

The forth equation, (x + 6)² + y² = 144, doesn't represent a circle with a diameter of 12 units, because the value of the equation is 144 which is not equal to the square of the radius.

The fifth equation, x2 + (y + 8)² = 36, doesn't represent a circle with a diameter of 12 units, because the value of the equation is 36 which is not equal to the square of the radius.

Step-by-step explanation:

The probability of the following event. The first die is 3 or the sum is 6 would be 1/4.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

All events must have a probability of occuring at least once, or 1.

The proportion of positive outcomes to all outcomes is referred to as the probability formula.

Let's assume that the blue die came up first among the two.

A = the amount of times we roll a first-die and get a 3.

B is the quantity of times a total of six occurs.

Now Locate 3 on the blue die and notice there are 6 occurrences when this happens which corresponds to the 6 other possibilities for the red die. So we have A = 5.

Also,there are 5 occurrences of the sum "6" in the table. So B = 5.

We have A+B = 5+5 = 10 occurrences of either the first die is 3 or the sum is 6.

However, we have to subtract off 1 because we double counted "6" when adding A and B.

So in reality we have 10-1 = 9 times this happens.

This is out of 36 total ways to roll two dice.

Therefore, the probability of the following event.

The first die is 3 or the sum is 6 would be 9/36 = 1/4

Greetings from Brasil...

First let's define the rational number....

→ Division between two numbers with the detail that the dividend or denominator cannot be zero

A/B or A ÷ B

where B ≠ 0

(just for the sake of knowledge. If B = 0 we would have +∞ as an answer)

A ∈ ℤ

and

B ∈ ℤ*   (B ≠ 0)

In this way, when dividing A by B, we will obtain a whole number or a number with a decimal (finite decimal or periodic tenth)

Let's go to the alternatives

4 ∈ ℤ and 5 ∈ ℤ*, so we have a rational number

B = √27 = 5.1961524227066318805823390245176

(There is no repetition of tithing periods (numbers after the point) - non-periodic tithe). So we have an Irrational Number

C = 4.020020002000002

There is no periodic tenth - Irrational Number

Out of the given choices, we choose 'not enough information given to answer this question' and concluded that  the true slope for the population is equal to zero.

Since, we are given a p-value associated with a test of the slope coefficient equal to 0.028 which leads to 3% level of significance, it means that there is 3% chance of finding difference which is larger than the one given in our study given that the null hypothesis is true. Since, it is less than 5% level of significance, the null hypothesis is rejected and accept an alternative hypothesis. As this hypothesis is not given, we conclude that there is not enough information to give an answer to the question.

The amount of gas that is left in the tank if there is only 1 / 8 of the tank is 1.5 gallons

The car tank can accommodate 12 gallons of gas .

Her fuel gauge says that there is 1 / 8 of the tank left in the car tank.

Therefore, the amount of gas that is left in the tank is calculated as follows:

amount left in the tank = 1 / 8 × 12

amount left in the tank = 12 / 8

amount left in the tank = 6 / 4

amount left in the tank = 3 / 2

amount left in the tank = 1.5 gallons

The standard error is of 0.2246, which means that the mean scores for samples of 30 vary around 0.2246 from the mean.

The confidence interval is the range of values that you expect your estimate to fall between a certain percentage of the time if you run your experiment again or re-sample the population in the same way.

The confidence interval formula is \(\bar x\pm t\frac{s}{\sqrt{n}}\).

Where, \(\bar x\) is the sample mean, t is the critical value, n is the sample size and s is the standard deviation for the sample.

Here,

\(\bar x\) =1.267, s=1.23, n=30

The standard error is Se= 1.23/√30

= 0.2246

Item a:

The standard error is of 0.2246, which means that the mean scores for samples of 30 vary around 0.2246 from the mean.

Item b:

Using a t-distribution calculator, considering a confidence level of 0.99 with 30 - 1 = 29 df, the critical value is t = 2.7564.

\(\bar x\pm tS_c\)

\(\bar x+ tS_c\) =1.267-2.7564(0.2246) =0.6479

\(\bar x- tS_c\) =1.267+2.7564(0.2246) =1.8861

Therefore, the 99% confidence interval to estimate the true mean score on this question is (0.6479, 1.8861). It means that we are 99% that the true mean score of all students in this question is between 0.6479 and 1.8861.

The calculated value of the force of the resistance is 15.62 N

We can use Newton's Second Law of Motion to solve this problem. The formula is:

F = m*a

where F is the net force, m is the mass of the object, and a is the acceleration.

In this case, the brick is falling through water, so there are two forces acting on it:

The net force is the difference between these two forces:

F_net = F_gravity - F_resistance

The weight of the object is:

F_gravity = m*g

So, we have

F_gravity = 2 kg * 9.81 m/s^2 = 19.62 N

Now we can use the formula for net force to find the force of water resistance:

F_net = F_gravity - F_resistance

F_resistance = F_gravity - F_net

F_resistance = 19.62 N - m*a

This gives

F_resistance = 19.62 N - 2 kg * 2 m/s^2 = 15.62 N

Therefore, the force of water resistance is 15.62 N.

Using the Venn Diagram principles, the number of customers at the supermarket who purchased both shirts and pants is 26.

A Venn Diagram shows a pictorial or graphical representation of the relationship (similarities and differences) between data sets.

In a Venn Diagram, overlapping circles or other shapes can be used to depict the logical relationships between two or more data sets or items.

The total number of customers at a supermarket = 118

The number of customers who purchased shirts, n(A) = 45

The number of customers who purchased pants, n(B) = 59

The number of customers who purchased neither shirts nor pants = 40

Let the number of customers who purchased both shirts and pants = n(A ∩ B)

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

n(A) = 45 n(B) = 59 n(A ∪ B) = 118 - 40 = 78

Substituting values:

78 = 45 + 59 - n(A ∩ B)

Solving for n(A ∩ B), we get:

n(A ∩ B) = 45 + 59 - 78 n(A ∩ B) = 26

Thus, using the formula of Venn Diagram, we can conclude that at this supermarket with 118 customers, 26 customers purchased both shirts and pants.

Answer:

m = 25 + 6n

Step-by-step explanation:

To write a function for the amount of money Makayla spent going to the movies during the club, you need to consider two things: the annual registration fee and the discounted ticket price. The annual registration fee is a fixed amount that does not depend on the number of movie tickets Makayla purchases. The discounted ticket price is a variable amount that depends on the number of movie tickets Makayla purchases. You can use a letter, such as n, to represent the number of movie tickets Makayla purchases. Then, you can write an expression for the amount of money Makayla spent on movie tickets, which is 6 times n, or 6n. To find the total amount of money Makayla spent going to the movies during the club, you need to add the annual registration fee and the amount of money spent on movie tickets. This gives you the expression 25 + 6n. You can use another letter, such as m, to represent the total amount of money Makayla spent going to the movies during the club. Then, you can write an equation that relates m and n, which is m = 25 + 6n. This equation is a function that models the amount of money Makayla spent going to the movies during the club as a function of the number of movie tickets she purchased.

Answer:

x is any integer except for -1

Step-by-step explanation:

If you substitute -1 for x, the denominator value would be 0, or undefined.

For this reason, x cannot be -1, which is mathematically known as an extraneous value.

The ball is in the air for approximately 2.8 + √7 seconds, which rounds to 5.2 seconds when rounded to one decimal place.To write the equation in vertex form, we need to complete the square.

The given equation is h = -4.9t² + 27.44t + 0.584. We can rewrite it as:

h = -4.9(t² - 5.6t) + 0.584

Now, we want to complete the square inside the parentheses. To do this, we need to add and subtract the square of half the coefficient of t. In this case, the coefficient is -5.6, so we have:

h = -4.9(t² - 5.6t + (5.6/2)² - (5.6/2)²) + 0.584

Simplifying, we get:

h = -4.9((t - 2.8)² - 2.8²) + 0.584

Expanding further:

h = -4.9(t - 2.8)² + 4.9(2.8)² + 0.584

Thus, the equation in vertex form is: h = -4.9(t - 2.8)² + 34.328

b) The ball's height when it was hit can be found by evaluating the equation at t = 0:

h = -4.9(0 - 2.8)² + 34.328

h = -4.9(-2.8)² + 4.328

h = -4.9(7.84) + 34.328

h ≈ 0.784 meters

To find the time at which the ball reaches its maximum height, we can use the fact that the maximum height occurs at the vertex of the parabolic equation. The vertex of a parabola in the form h = a(t - h₀)² + k is given by (h₀, k). Comparing this to our equation, we can see that the vertex occurs at t = 2.8 and h = 34.328. Therefore, the ball reaches its maximum height at 2.8 seconds, and the maximum height is 34.328 meters.

The total time the ball is in the air can be determined by finding the time it takes for the ball to reach the ground. When the ball hits the ground, its height is 0. To find this time, we can set the equation equal to 0 and solve for t:

0 = -4.9(t - 2.8)² + 34.328

4.9(t - 2.8)² = 34.328

(t - 2.8)² ≈ 7

t - 2.8 ≈ ±√7

t ≈ 2.8 ± √7

Since time cannot be negative in this context, we can ignore the negative value.
