My mom packed my lunch three of the past five days, so the probability of my mom packing my lunch is 3/5. Is this Experimental or Theoretical?
Answer:
definitely theoretical. Seems how mom packed the lunch 3/5 times a week, the pattern will follow
Step-by-step explanation:
The given probability is the theoretical probability.
Given that, my mom packed my lunch three of the past five days, so the probability of my mom packing my lunch is 3/5.
What are theoretical and experimental probabilities?Experimental probability is based on the results of several trials or experiments. Theoretical probability is calculated by taking the number of favourable outcomes over the total number of outcomes. Experimental probability is calculated by taking the actual outcomes over the total number of trials.
Now, my mom packed my lunch for three days of the past five days.
Number of favourable outcomes=3
Total number of outcomes=5
Probability of an event =3/5
Therefore, the given probability is the theoretical probability.

The two angles ∠1 and ∠3 are equal by the alternate exterior property.
What are lines and angles?Straight lines with little depth or width are present. You will learn about a number of lines, including transversal, intersecting, and perpendicular lines.
A figure called an angle is one in which two rays originate from the same point. In this area, you could also encounter contrasting and related viewpoints.
According to the alternate outside angle theorem, alternate exterior angles are regarded as congruent angles or angles of equal measure when two parallel lines are intersected by a transversal.
Here the two angles ∠1 and ∠3 are alternate exterior angles and are equal to each other.

1.A cell phone is advertised for 25% off the list price of D dollars. Write an algabraic expression that represents the sale price of the phone?
2. A car travels for 10 hours at an average speed of s miles per hour, write an algabraic expression that represents the total distance traveled by a car.
Answer:
$0.75D ; 10s miles
Step-by-step explanation:
1)
Given that:
List price of phone = $D
Advertised price = 25% off the list price
Hence, sales price of phone :
(100% - 25%) × list price
Sales price = 75% × $D
Sales price = $0.75D
2)
Given that :
Time of travel = 10 hours
Speed of travel = s miles per hour
Total distance traveled = (speed of travel × time of travel)
Total distance traveled = (10 * s) miles

Skyler competes in the high jump event at her school. She hopes to tie or break some records at the next meet.
You can drag Skyler to see possible heights for the high jump bar.
A. Write and solve an equation to find x, the number of meters Skyler must add to her personal best to tie the district record.
Enter your answer.
B. Look for Relationships Rewrite your equation as an inequality to represent the situation where Skyler breaks the district record. How is the value of x in the inequality related to the value of x in the equation?
Equations are expressions that have equal values, while inequalities are used to represent unequal expressions
The number of meters Skyler must add is 0.09The inequality that represents the scenario is [tex]x + 1.48>1.57[/tex]How to determine the number of metersFrom the question,
Skyler's personal best is 1.48 meters highThe high jump bar is 1.57 meters highThe number of meters (x) Skyler must add is represented using the following equation
[tex]x + 1.48 = 1.57[/tex]
Solve for x
[tex]x = 0.09[/tex]
The inequalityTo break the record, the number of meters added to his personal best must be greater than 1.57.
So, we have:
[tex]x + 1.48>1.57[/tex]
Solve for x
[tex]x > 0.09[/tex]
Hence, the number of meters Skyler must be greater than is 0.09 meters

The measures of two angles of a triangle are each four times the measure of the third angle. What is the measure of the third angle? (hint: The sum of the angle measure of a triangle are 180°)
Answer:
20°
Step-by-step explanation:
The sum of all triangles must equal 180 degrees.
The measure of two angles of a triangle are each four times the measure of the third angle.
2x+x/4=180
The equation above illustrates a way to solve for X which represents the the independent angle measurement from the two angles.
x = 80
Above, we solved for x by simplifying both sides of the equation and then isolating x. So hmm...does 80 make sense?
80 / 4 = 20. So it is four times the measure of the 3rd angle. But does it all equal to 180?
2 * 80 + 20 = 180.
The angle of the third angle is 20 degrees.
The total number of triangles must be 180 degrees, and the two angles of a triangle are measured every four times the third angle measurement. So, the calculation can be defined as follows:
[tex]\to \bold{2x+ \frac{x}{4}=180}[/tex]
The above equation illustrates a way of resolving the indie angle measurement from both angles for X.
[tex]\bold{x = 80}[/tex]
Above we solved x through simplification and isolation of the x on both sides of the equation.
So 80 is meaningful.
[tex]\frac{80}{4 }= 20.[/tex] Thus, 4 times the 3rd angle measurement. But it all equates to 180.
[tex]\to \bold{ 2+4 = 2 \times 80 + 20.}[/tex]
Therefore, the third angle is 20 degrees.

evaluate r(x) = -x -7 when x = -2, 0, and 5
Answer:
r(-2) = -5 , r(0) = -7 , r(5) = -12
Step-by-step explanation:
Plug in the numbers for x and then solve. : )
r(-2) = - (-2) - 7
r(-2) = 2 -7
r(-2) = -5
r(0)= -0 -7
r(0)=0-7
r(0) = -7
r(5) = -5 - 7
r(5) = -12
The values of r(x) for x = - 2, 0 and 5 are obtained by Substituting the values for x in the function, hence the values are :
r(-2) = -9r(0) = -7r(5) = -2When x = - 2
Substitute the value of x = - 2 into the function r(x) = - x - 7 r(-2) = - 2 - 7 = - 9When x = 0
Substitute the value of x = 0 into the function r(x) = - x - 7 r(-2) = 0 - 7 = - 7When x = 5
Substitute the value of x = 5 into the function r(x) = - x - 7 r(-2) = 5 - 7 = - 2Therefore, the required values are - 9, - 7 and - 2
