To meet her goal of riding a total of 28.8 miles, Keilantra needs to ride an average of 6.2 miles.

Here we know that Keilantra wants to rude her bicycle for a total of 28.8 miles.

We know that she has already ridden 4 miles, so the distance left to meet her goal is:

D = 28.8mi - 4mi = 24.8mi

Now we know that she wants to meet her goal in 4 days, so the average that she needs to ride in each of these 4 days is given by the quotient:

24.8mi/4 = 6.2 mi

To meet her goal, Keilantra needs to ride an average of 6.2 miles.

The coordinates of point E is (-2, -1.5)

How to determine the coordinates of point E?

see in the file attached below

The given parameters are

C = (1, 6)

D = (-3, -4)

The ratio 3/4 can be represented as:

m : n = 3 : 1

So, the coordinate of point E is

E = 1/(m + n) * (mx2 + nx1, my2 + ny1)

So, we have:

E = 1/(3 + 1) * (3 * -3 + 1 * 1, 3 * -4 + 1 * 6)

Evaluate

E = 1/(4) * (-8, -6)

This gives

E = (-2, -1.5)

Answer: A

Step-by-step explanation:

Angles on a straight line must add up to 180 so angle BCA is 180-132=48

Because the triangle BAC is an isosoles angle BCA and ABC must be the same so 48

We can now use the angle on a straight line rule to figure out angle DBA 180-48=132

We know that triangle DBA is an isosoles trianlge so and x and DAB must be the same and both be x, and we know that angles in a triangle add up to 180 so the equation can be written as:

180=2x+132

48=2x

It was discovered that the pressure in atmospheres (atm), when applied to a balloon, was inversely related to the height in meters, squared root. The pressure was 1.44 atm when the balloon was 25 meters height in the air. What was the pressure like at a 9-meter height?

The pressure is 2.4 atm when the height is 9m.

Inversely proportion means when one variable is directly proportional to the reciprocal of the other, there is an inverse fluctuation between the two variables. In other words, the two variables' product has a fixed value. Therefore, as one variable rises, the other falls.

Here, We take pressure of atmosphere as P and the height of the balloon as H.

Given that, The pressure of atmosphere was inversely proportional to the square root of the height.

We write this as [tex]P[/tex]∝[tex]\frac{1}{\sqrt{H} }[/tex].

Taking constant of the proportionality as k.

[tex]P[/tex]=[tex]\frac{k}{\sqrt{H} }[/tex].

We have, The pressure was 1.44 atm when the balloon was 25 meters height in the air.

P=1.44 and H=25

[tex]1.44=\frac{k}{\sqrt{25} }[/tex].

[tex]1.44=\frac{k}{5}[/tex]

[tex]k=5\times1.44[/tex]

[tex]k=7.2[/tex]

Now [tex]P=\frac{7.2}{H}[/tex]

We have to find If H is 9m then what is P?

[tex]P=\frac{7.2}{\sqrt{9} }[/tex]

[tex]P=\frac{7.2}{3}[/tex]

[tex]P=2.4\\[/tex]

Therefore, The pressure is 2.4 atm when the height is 9m.

The truth value of the conditional statement is false

How to determine the truth value of the conditional statement?

The conditional statement is given as

“If a number is greater than -500, then the number is greater than 500.”

The above conditional statement is false

This is because not all numbers greater than -500 are greater than 500

for example 450 is greater than -500, but less than 500 that is the number between -500 and 500 will not satisfy the above statement.

Hence, the truth value of the conditional statement is false

Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A

The given parameters are:

Exam A

Score = 710

Mean = 700

Standard deviation = 25

Exam B

Mean = 200

Standard deviation = 50

The z-score is calculated as

z = (Score - Mean)/Standard deviation

For exam A, we have

z = (710 - 700)/25

z = 0.4

For exam B, we have

z = (Score - 200)/50

Substitute z = 0.4 in z = (Score - 200)/50

0.4 = (Score - 200)/50

This gives

Score - 200 = 20

Add 200 to both sides

Score = 220

The slope of equation  y = -5/6 x + 4 is -5/6 and the slope-intercept form of -5/6x+4 is y = -5/6 x + 4

The slope of a function y = f(x) is given by a formula

slope = y2-y1 / x2- x1

where ( x1 , y1) and (x2, y2) are coordinates of any two points on the line of graph representing y = f(x)

Or we can simply use the slope-intercept form

y = mx+ c

where m is the slope of the given equation and c is the constant

so, in  the given equation y = -5/6 x + 4

slope of the equation is -5/6

Hence, The slope of equation  y = -5/6 x + 4 simply is -5/6 and the slope intercept form of -5/6x+4 is y = -5/6 x + 4

When you know the slope of the line to be investigated and the point given is also the y intercept, you can utilize the slope intercept formula y = mx + b. (0, b). The y value of the y intercept point is represented by b in the formula.

Equivalent expressions are those expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). They are same but looks different.

Given that, x(2x+5) = 3 and 2x²+5x = 3 and we have to conclude how both expressions are related to each other.

Let's procced to solve this.

x(2x+5) = 3 ..............(1)

2x²+5x = 3 ...............(2)

Now, solving equation (1), we get

x(2x+5) = 3 ⇒2x²+5x = 3, which is equation (2)

NUSS is a device for propagating multigroup nuclear information covariances in pointwise ace-formatted nuclear information the use of stochastic sampling method.

Stochastic sampling (SS) method for quantifying nuclear facts uncertainties is finished with the resource of the use of the use of perturbed nuclear facts in recurring neutronics calculations and identifying the variance of output parameters due to the input nuclear facts uncertainties. In this work, an SS-based absolutely device, called NUSS is carried out which perturbs pointwise ACE-formatted nuclear facts the use of multigroup nuclear facts covariance. The use of pointwise ACE-formatted nuclear facts in NUSS can accommodate flexible multigroup covariance structures and allows for nuclear facts uncertainty propagation through the continuous/pointwise-energy delivery code MCNPX.
