We have, The quantity of tomatoes prepared by Lorraine = 4.5 gallon
The quantity of tomatoes which is hold by one jar = 1.5 quarts
As we know quarts and gallon are two basic units of measurement units. Also , we have
Total quantity to fill up in jars = 4.5 gallon
Conversion of measurement units : In terms of quarts units, one gallon quantity = 4 quarts
4.5 gallon quantity = 4 × 4.5 quarts
= 18.0 quarts.
Now, time's to determine how Maany jars Lorraine fill.
1.5 quarts tomatoes quantity filled up = one jar
1 quarts tomatoes quantity will fill = 1/1.5 jar
18 quarts tomatoes quantity will fill or number of jar that lorraine fill = 18× 1/1.5 = 18/1.5

Answer:

Step-by-step explanation:
i took the test :)
A movie theater has a seating capacity of 217. The theater charges $5. 00 for children, $7. 00 for students, and $12. 00 of adults. There are half as many adults as there are children. If the total ticket sales was $ 1558, How many children, students, and adults attended?
The probability that the theater had 108 children, 108 students, and 54 adults attend, for a total of $1558 in ticket sales.
Total ticket sales = $1558
Adult ticket sales = $12 x 54 = $648
Remaining ticket sales = $1558 - $648 = $910
Student ticket sales = $7 x 108 = $756
Children ticket sales = $910 - $756 = $154
Children = $154 / $5 = 108
Students = $756 / $7 = 108
Adults = 108 / 2 = 54
The theater had a total ticket sales of $1558, with adults tickets being $12 each. By subtracting the adult ticket sales from the total, we get the remaining ticket sales. We then divide this by the student ticket price of $7 to get the number of students. Subtracting this from the remaining ticket sales gives us the amount of children ticket sales. We divide this by the children ticket price of $5 to get the number of children. Finally, we divide the number of adults by 2 to get the number of adults.

was his velocity?
From Logan's home to Elizabeth's home, he skateboarded 3,200 metres to the southwest. He skated quarter of the way to her house at a consistent speed in 4 minutes. 200 meters / minute is the Velocity.
How can you determine velocity?The vector quantity velocity (v) quantifies displacement (or change in position, s), over change in time, according to the equation v = s/t (t). According to the equation r = d/t, speed (or rate, r) is a scalar quantity that indicates the amount of time (t) spent traveling across the distance (d).
You can determine an object's beginning velocity by dividing the total distance travelled by the time it took the object to travel a specific distance. In the equation V = d/t, d stands for distance, t for time, and V for velocity. An object's velocity determines how quickly it moves. It can be defined as the position change of an item divided by time.
Given total distance = 3200 meters,
one - fourth of 3200 = 800 meters,
Time taken = 4 minutes
Velocity = Distance / Time
Velocity = 800 meters / 4minutes,

The probability that there are more than 120 errors in a certain data packet is:
P(X > 120) = 1 - P(X <= 120)
We are given, each data packet consists of 1000 bits. Due to noise, each bit may be received in error with a probability of 0.1. It is assumed that bit errors occur independently. The goal is to find the probability that there are more than 120 errors in a certain data packet.
To find the probability that there are more than 120 errors in a data packet, we can use the cumulative distribution function (CDF) of the binomial distribution:
P(X > 120) = 1 - P(X <= 120)The number of errors in a data packet can be modeled as a binomial random variable with n = 1000 (number of bits in the packet) and p = 0.1 (probability of a bit error).
Where X is the number of errors in the data packet.
The cumulative distribution function of the binomial distribution can be calculated using the formula:
P(X <= k) = Summation(i=0 to k) ( (n choose i) * (p^i) * ((1-p)^(n-i)) )
Plugging in the values we get:
P(X > 120) = 1 - P(X <= 120) = 1 - (summation(i=0 to 120) ( (1000 choose i) * (0.1^i) * (0.9^(1000-i)) ))

Also, she had 100 dollars when she was 8 years.
Thus, the total money she has= 500+100= 600 dollars
Hence, Sandra has 600 dollars in the account now.

Please help!! circular flower bed is 20 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk in square meters.
The area of the sidewalk is 144π square meters.
Describe area of a circle?The area of a circle is a measure of the amount of space inside the circle. It is defined as the product of Pi (π) and the square of the radius of the circle.
A = π × r²
The radius is the distance from the center of the circle to its edge. The area of a circle is a scalar quantity and is typically expressed in square units, such as square centimeters or square meters.
The diameter of the circular flower bed is 20 m, so its radius is 20/2 = 10 m.
The sidewalk around the flower bed is 2 m wide, so the radius of the circular sidewalk is 10 + 2 = 12 m.
The area of a circle can be found using the formula:
A = πr^2
So the area of the circular sidewalk is:
A = π × 12²= π × 144 = 144π m²
Therefore, the area of the sidewalk is 144π square meters.

Answer: 678900 to the 10 power
Step-by-step explanation:
What is the distance between the points 2 0 and (- 2 0?
16 units are the distance between the two points (2, 0) and (-2, 0).
What is the distance?An object's distance is determined by its total velocity, regardless of direction.
Regardless of where it started or ended, distance is the amount of space that an object has covered.
We can determine an object's true size by knowing how far it is from us.
Usually, the formula shown below is used to calculate the separation between two points: d=((x2 - x1)2 + (y2 - y1)2)
So, the distance formula is:
d=((x2 - x1)2 + (y2 - y1)2)
Points are: (2, 0) and (-2, 0)
Now, enter the numbers in the formula above and do the following calculation:
d=((x2 - x1)2 + (y2 - y1)2)
d=(-2 - 2)2 + (0 - 0)2)
d=(-4)²
d=16
Therefore, 16 units are the distance between the two points (2, 0) and (-2, 0).

Given that Justin is collecting data on reaction time, what type of data is he working with?
Select the correct answer below:
A. qualitative
B. discrete quantitative
C. continuous quantitative
D. none of the above
Since reaction time is measured and not constrained to a specific range of numbers, it is continuous quantitative data.
'What is continuous quantitative?'
A continuous data set is a quantitative data set that represents a scale of measurement that includes fractions and decimals in addition to whole integers. Values like height, weight, length, temperature, and other similar metrics would be included in continuous data sets. They are items that can be quantified in decimals and fractions. A continuous data set typically requires the use of a tool, such as a ruler, measuring tape, scale, or thermometer, to create the numbers.

The relationship between attending your classes and passing your classes would best be described as:
Causal
Correlation
Spurious Correlation
No relationship
It will be best defined as a spurious correlation rather a casual correlation.
What is a spurious correlation?
A spurious correlation occurs when two variables are correlated but don’t have a causal relationship. In other words, it appears like values of one variable cause changes in the other variable, but that’s not actually happening.
If you look up the definition of spurious, you’ll see explanations about something being fake or having a deceitful nature. It has the outward appearance of genuineness, but it’s an imitation. With this definition in mind, spurious correlations look like causal relationships in both their statistical measures and in graphs, but it’s not real.
For example, ice cream sales and shark attacks correlate positively at a beach. As ice cream sales increase, there are more shark attacks. However, common sense tells us that ice cream sales do not cause shark attacks. Hence, it’s a spurious correlation.
Now,
As attending classes is not related to passing the class because one can pass an examination without attending classes.

Why does the distance formula work?
In addition to many other things, it assists with the construction of new structures and with locating potential places and new routes for emergency situations. As a result, it's important to learn how to calculate the distance between two points in two and three dimensions.
In math, what is a distance?
The length of the segment of the line that connects the supplied two points determines the distance between them.
The shortest segment of a line connecting a point to a line will have a length equal to the distance between them.
Why does the distance formula work?
The Pythagorean Theorem, which states that a side plus a side plus a side equals a side equals a side equals a side equals a side equals a side equals a side equals a side equals a side, is where the Distance Formula actually originates (known as the legs of a right triangle).
