The weight lies between the whole numbers 8 and 9.
The length, breadth, and height of a package are multiplied using the longest point on each side to determine the dimensional (DIM) weight.
If each of the 4 boxes has the same weight, the weight of each box can be found by dividing the total weight by the number of boxes. Given that the total weight is 34 kilograms, the weight of each box is:
w = 34 kg / 4 boxes = 8.5 kg
So, each box weighs 8.5 kilograms. The weight lies between the whole numbers 8 and 9.

The probability that the student will be a student who lives on campus is 0.24
In math the term probability is referred as the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
Here we have given that one full-time student who is a freshman or sophomore is selected at random.
Here we need to find the probability that the student will be a student who lives on campus.
Here we know that the probability that a student is a sophomore is calculated as,
=> P(S) = 19/42 = 0.45.
Whereas the probability that a student has a freshman is calculated as,
=>P(H)=25/42=0.6.
Then the probability that the student will be a student who lives on campus is calculated as,
=> P(H∩S)=P(S)+P(H)−P(S∪H)
Apply the values then simplify this one then we get,
=> 0.45+0.6−(42−8)/42=0.24

In each question, lines AI and GJ are parallel and intersected by the transversal line FE.
Angles EBI and BCJ are corresponding angles. Use a transformation that takes angle EBI to angle BCJ to prove that corresponding angles are congruent
Angle EBI and angle BCJ are congruent is proved as follow.
To prove that corresponding angles are congruent, we can use the transformation that takes angle EBI to angle BCJ.
First, we place angle EBI in the plane.Next, we use a transformation, such as a translation or rotation, to move angle EBI to the position of angle BCJ.Since the transformation preserves the angle measure and the angles have been superimposed on each other, we can see that angle EBI and angle BCJ have the same measure.Therefore, we can conclude that corresponding angles are congruent.
Alternatively, we can use the fact that if two lines are parallel, then the alternate interior angles are congruent and corresponding angles are congruent. Since AI and GJ are parallel, angle EBI and angle BCJ are congruent.

Olivia flips a coin and rolls a number cube with sides labeled 1, 2, 3, 4, 5, and 6. After 90 trials of the experiment, the relative frequency of flipping heads and rolling a number less than 3 is 2/15 . What is the difference between the number of expected outcomes and the number of actual outcomes?
Answer:
3
Step-by-step explanation:
Experimental probability is based on the actual outcomes of an experiment (gathered by experimenting repeatedly).
Theoretical probability is based on the possible outcomes (expected outcomes).
Probability formula
[tex]\boxed{\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}}[/tex]
Theoretical probability of flipping a head
A coin has two sides: one side is a "head", the other side is a "tail".
The number of ways flipping a head can occur is 1.
The total number of possible outcomes is 2.
Therefore, the theoretical probability of flipping a head is 1/2.
Theoretical probability of rolling a number less than 3
The cube has six sides labelled 1, 2, 3, 4, 5 and 6.
The number of ways that rolling less than 3 can occur is 2 (rolling 1 or 2).
The total number of possible outcomes is 6.
Therefore, the theoretical probability of rolling a number less than 3 is 2/6 = 1/3.
Therefore, the theoretical probability of flipping a head and rolling a number less than 3 is:
[tex]\sf P(head)\; and\; P(X < 3)=\dfrac{1}{2} \times \dfrac{1}{3}=\dfrac{1}{6}[/tex]
To calculate the number of actual outcomes and expected outcomes after 90 trials, multiply the number of trials by the probability for each outcome:
[tex]\textsf{Number of actual outcomes}=90 \times \dfrac{2}{15}=12[/tex]
[tex]\textsf{Number of expected outcomes}=90 \times \dfrac{1}{6}=15[/tex]
Therefore, the difference between the number of expected outcomes and the number of actual outcomes is:
[tex]\implies 15-12=3[/tex]
Note: If Olivia continued to flip the coin and roll the number cube, as the number of trials increased, we would expect the experimental probability of 2/15 to get nearer to the theoretical probability of 1/6 and so the difference between the number of actual and expected outcomes would become smaller.
is the tendency for extreme scores on one variable to be followed by, or accompany, less extreme scores on another. a. the extreme return effect b. regression to the mean c. the robust average effect d. extreme minimization
The majority of human physical, mental, and personality factors have a mean in the middle of the distribution, where there are also the most cases. For example, in baseball, the rookie of the year often has a poor second season.
Correct answer is b) regression to the mean.
Regression to the mean is the propensity of outcomes that are extreme by chance on the first measurement to move closer to the average when tested a second time. Results that are susceptible to regression to the mean are those that are vulnerable to some degree of chance. When exceptional scores are the result of chance or a fluke, it's improbable that those extreme scores will be obtained again.

The association between the two sets of data in the scatterplot is; Positive.
What is the association of the scatterplot?A scatter plot is a graph that shows the association that exists between two variables. A scatter plot matrix shows all the pairwise scatter plots for a lot of variables.
Now, If the variables tend to increase and decrease together, the association is said to be positive. However, If one variable tends to increase as the other decreases, then the association is said to be negative. Finally, If there is no pattern, then the association is said to be zero.
When a straight line is used to describe the relationship between the variables, then the association is said to be linear. When a constantly increasing or decreasing nonlinear function describes the relationship, the association is monotonic.
The scatterplot given shows us that the association is positive as increasing x values lead to increasing y values.

Harper and Joe want to buy season passes for Disneyland but neither of them has the $1,300 needed to purchase a pass. Harper decides to get a job that pays $25 a week. She has nothing saved right now. Joe already has $80 and plans to save $15 of her weekly allowance.
a) When will they have the same amount of money saved up? How much money will they both have?
b) How long will it take each of them to save up for the season pass?
They needed a total of 8 weeks to save the same amount of money, and after 8 weeks, everyone would have $200.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, Harper and Joe want to buy season passes for Disneyland but neither of them has the $1,300 needed to purchase a pass.
Since Harper decides to get a job that pays $25 a week. She has nothing saved right now. Joe already has $80 and plans to save $15 of her weekly allowance.
To save up for the season pass:
Harper needs = 1300$
Since, She earns 25$ a week
Harper needs total weeks = 1300/25
Harper needs total weeks = 52 weeks
joe also needs 1300 $
Since, joe already has $80 and plans to save $15 of her weekly allowance.
Joe needs total weeks = (1300 -80)/15
Joe needs total weeks = 81.33
To have the same amount of money saved up:
Let "x" be the weeks they required to save the equal money:
25 *x = 80 + 15*x
10*x = 80
x = 8
Everyone will have = 25 * 8
Everyone will have = 200$
Therefore, they required total of 8 weeks to have the same amount of money saved up and everyone will have 200$ after 8 weeks.

Answer:
SEE ATTACHED
Step-by-step explanation:
For the vectors u = (-4,-1) and v= (1,3), express u as the sum u=p+n, where p is parallel to v and n is orthogonal to v. + 7 21 33 11 u=p+n= 10 10 10 10 (Type integers or simplified fractions. List the terms in the same order as they appear in the original list.)
The vector u can be expressed as a sum of n and p when n= (-33/10, 11/10) and p= (-7/10, -21/10).
To find the vector p that is parallel to v, we need to project u onto v. We can use the formula for projection:
p = (u . v) / (||v||^2) * v
where . represents dot product and ||v|| represents the magnitude of v.
First, we need to find the dot product of u and v:
(-4,-1) . (1,3) = -4*1 + -1*3 = -4 + -3 = -7
Next, we need to find the magnitude of v:
||v|| = sqrt(1^2 + 3^2) = sqrt(1 + 9) = sqrt(10)
Then, we can plug these values into the projection formula:
p = (-7) / (sqrt(10))^2 * (1,3) = (-7/10) * (1,3) = (-7/10, -21/10)
So the vector p that is parallel to v is (-7/10, -21/10)
To find the vector n that is orthogonal to v, we can subtract p from u:
n = u - p = (-4,-1) - (-7/10, -21/10) = (-4 + 7/10, -1 + 21/10) = (-33/10, 11/10)
