Find the slope of the line passing through the points (-4, 4) (-4, -2)

The number of data points above the median is 12, number of data points below the 1st quartile is 6 and the number of data points between 1st and 3rd quartile is 12.

Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.

There are 24 data points in a data set.

Let x₁, x₂, .........., x₂₄ be the data points arranged in an increasing order.

Since the number of elements are even, median is the average of middle two elements.

Median = (x₁₂ + x₁₃) / 2, which will be in the middle of x₁₂ and x₁₃.

Number of elements above median = number of elements from x₁₃ to x₂₄ = 12

First quartile range is the average of the first part of elements which has been divided by the median.

Average of x₁, x₂, ......., x₁₂

1st quartile, Q₁ = (x₆ + x₇) / 2, which is located in the middle of x₆ and x₇.

Number of data points below 1st quartile = 6

Third quartile  is the average of the second part of elements which has been divided by the median.

Average of x₁₃, x₁₄, ......., x₂₄

3rd quartile = (x₁₈ + x₁₉) / 2, which is located in the middle of x₁₈ and x₁₉.

Number of elements between 1st and 3rd quartile = 12

Hence the number of elements in each of the range is found.

Answer:

The escape velocity from Earth is approximately 415.9 miles per hour.

Correct, in a hypothesis test using an F-test, the significance level refers to the probability of rejecting the null hypothesis when it is actually true.

The F-test is a statistical test used to determine if there is a significant linear relationship between two variables.

In the F-test, the null hypothesis is that there is no linear relationship between the variables, while the alternative hypothesis is that there is a linear relationship. When the significance level (usually denoted by alpha) is set to a small value, such as 0.05, we can use the F-test to determine if the observed relationship between the variables is likely due to chance or if it is a real, significant relationship.

If the calculated F-value is greater than the critical value for the given significance level, we reject the null hypothesis and conclude that there is a significant linear relationship between the variables.

On the other hand, if the calculated F-value is less than the critical value, we fail to reject the null hypothesis and conclude that there is not enough evidence to suggest a significant linear relationship between the variables.

The final velocity of the Tennis for the condition is 19 m/s.

acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

Given Tennis starts moving at 4m/s to the left,

initial speed = 4 m/s

for 5s he is accelerating at a constant rate of 3m/s^2

time = t = 5 s

acceleration = 3 m/s²

to find the final velocity​,

velocity is given by,

v = u + at

u = initial speed, t = time, and a = acceleration

v = 4 + 3(5)

v = 4 + 15

Answer:

The given equation 1 - x - 2y = -6 is in standard form, and can be converted to slope-intercept form (y = mx + b) by solving for y.

To do this, we first add x and 2y to both sides of the equation to get:

1 + x + 2y = -6

Next, we divide both sides of the equation by 2 to get:

(1/2) + (1/2)x + y = -3

Finally, we rearrange the equation to get:

y = -(1/2)x - 3

Therefore, the equation in slope-intercept form is y = -(1/2)x - 3.

Note that the statement that verified that ST || to QR is the converse of the Triangle Proportionality Theorem and the ratios given in Option A.

According to the converse of the Triangle Proportionality Theorem, If a line divides two sides of a triangle proportionally, then it is parallel to the third side.

The Theorem of Proportionality states that a line drawn parallel to one side of a triangle and cutting the other two sides splits the other two sides in equal proportion. The reverse of the Basic Proportionality Theorem - A line drawn to cut two sides of a triangle in equal proportion is parallel to the third side.

After 1 second, the height of the ball will be 48 feet above the ground, and if the ball lands after 4 seconds of being thrown into the air the ball is 50 feet above the ground after 4.66 seconds.

So we have the function:

h(t)=64t-16t²

height h(t) is measured as the ball after t seconds.

A) To find the height of the ball after 1 second if it has been thrown, then substitute 1 for t. Thus:

h(1)=64(1)-16(1)²

Simplify:

h(1)=64-16

Subtract:

h(1)=48

Thus, after 1 second, the height of the ball is 48 feet above the ground.

B) To know how many seconds after being thrown the ball hit the ground, we have to set h(t) to 0. 0 can be defined as that it will be 0 feet above ground level: in another word, on the ground. So:

0=64t-16t²

Solve for t. Factor out a 16t

0=16t(4-t)

Zero Product Property:

16t=0, 4-t=0

Solve for t:

t=0 or t=4.

We have to ignore the first zero. So, the value of t is 4 and the ball lands after 4 seconds of being thrown into the air.

C) To calculate at what time(s) the ball is 50 feet above the ground, set h(t) to 50 and solve for t:

50=64t-16t²

First, we have to divide everything in 2 to simplify things:

Now, to find the zeros, we can use the quadratic formula. a=-8, b=32, and c=-10. Thus:

[tex]x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]

Substitute:

[tex]x=\frac{-32+\sqrt{(32)^2-4(-8)(-10)} }{2(-10)}[/tex]

The logarithm is expanded as much as possible to, log √(x^7y^-4) = (7/2) log (x) + (-2) log(y).

Simplifying the given logarithmic expression, log √(x^7y^-4).

Use the power rule of logarithms, log(a^x) = x log a.

Say, x= 1/2 and a = (x^7y^-4).

log √(x^7y^-4) = (1/2) log (x^7y^-4)

Now, use the multiplication property of the logarithms, log (ab) = log(a) + log(b). Consider a = x^7 and b = y^-4.

log √(x^7y^-4) = (1/2) log (x^7) + (1/2) log(y^-4)

Now, again use the power rule in both the terms,

log √(x^7y^-4) = (7/2) log (x) + (-4/2) log(y)

log √(x^7y^-4) = (7/2) log (x) + (-2) log(y)

3 kids wanted to go surfing.

The final values of $t0, $t1, $t2, and $t3 in the MIPS assembly code are 1, 2, 3, and 4, respectively.

This is because each of the 'addi' instructions adds a constant value to the specified register. The 'addi' instruction in MIPS stands for "add immediate", where the constant value is immediately added to the source register. In this case, each of the 'addi' instructions adds 1, 2, 3, or 4 to the corresponding register.

[tex]$t0 = 0 + 1 = 1$$t1 = 0 + 2 = 2$$t2 = 0 + 3 = 3$$t3 = 0 + 4 = 4$[/tex][tex]$[/tex]

Assuming that the initial values of the registers are 0, the final values of $t0, $t1, $t2, and $t3 would be the sum of the constant value and the initial value of the corresponding register. Thus, the final values of $t0, $t1, $t2, and $t3 would be 1, 2, 3, and 4, respectively.
