A recipe says that 2 cups of dry rice will serve 6 people. Complete the table as you answer the questions. Be prepared to explain your reasoning.
How many people will 10 cups of rice serve?
How many cups of rice are needed to serve 45 people?
A recipe says that 6 spring rolls will serve 3 people. Complete the table
Answer:
1a. 10 cups of dry rice will serve 30 people.
1b. 15 cups of dry rice will serve 45 people.
2. 30 spring rolls = 15 people
40 spring rolls = 20 people
56 spring rolls = 28 people
Step-by-step explanation:
1a. To find a constant, the equation is y/x. When 6 is divided by 2, you get 3 and from there the input increases by 3. So, you multiply 10 by 3 to find how many people it can serve.
1b. To find this answer, you divide 45 by 3 to get 15. So 15 cups will serve 45 people.
2. Any number in the second column is divided by .5 to get the number in the first column. Any number in the first column is multiplied by .5 to get the number in the second column.

0.68 is a rational number and the reason is because:
It is a decimal that terminatesWhy is 0.68 a rational number?0.68 can be regarded as a rational number because it is a finite number that is also a fraction of two whole integers. In this case, the integers are 68 and 10. Another feature by which rational numbers are known is the fact that they are repeating in nature.
However, it is important to note that the decimal here is terminating in nature because it has a finite number of zeros behind the number 8. So, the reason for selecting 0.68 as a rational number is that it terminates.

Samuel was preparing for the triathlon. HE did 3 activities every morning:
ran for 30 minutes covering 4.5 miles
swam for 20 minutes,covering 2/3mile
biked for 45 minutes, covering 9 miles
What was Samuels average speed during his morning routine?
Giving brainliest
Samuel's average speed during his morning routine is 24.3 miles per hour.
What is the average speed?
Average speed measures how fast an object or a person is travelling with respect to time. Average speed is the ratio of total distance travelled and total time travelled.
Average speed = total distance / total time
Total distance = 4.5 + 2/3 + 9
= 4.5 + 9 + 0.67 = 14.2 miles
Total time = 30 + 20 + 45 = 95 minutes = 1 hour 35 minutes = 1 7/12 hours = 1.6 hours
Average speed = 14.2 / 1.6 = 24.3 miles per hour

Answer:
z = 54
Step-by-step explanation:
The sum of all interior angles in a polygon is given by the formula :
(n-2) × 180 (Where n is the number of sides) .
There are 5 sides so the sum of all interior angles will be :
(5-2) × 180 = 540°
So :
108 + 130 + 140 + 2z + z = 540
Simplify :
378 + 3z = 540
Subtract 378 from both sides :
3z = 540 - 378
3z = 162
Divide both sides by 3 :
z = 162 ÷ 3
z = 54

The equation of the parabola is y=
Equation is y = 2x² + 4x + 1.
What is parabola?A parabola is an approximately U-shaped, mirror-symmetrical planar curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.
Given Data
Standard form of quadratic equation
Y = ax² +bx + c
Given points
(3,9), (30,-9). (0,1)
Equating points in formula
9= a(3)² + b(3) + c
9 = 9a + 3b +c
-9 = a(30)² + 3(30) + c
-9 = 900a + 90 + c
1 = a(0)² + b(0) + c
c = 1
Equating c in the equation
9 = 9a + 3b +1
8 = 9a + 3b
-9 = 900a + 90b +1
-10 = 900a + 90b
Multiplying both sides by 100
800 = 900a + 300b
-10 = 900a + 90b

The mean and median of the data are equivalent and the value is 6.
The mean (average) of a data set can be calculated by adding up all the numbers in the collection and dividing by the total number of values in the set.
When a data set is sorted from least to greatest, the median is the middle. The value that pops up most frequently in a data set is its mode.Between the lowest and highest value is the range. You subtract the lowest value from the greatest value to calculate it.The exact midpoint between the lowest and highest values in a set of data is the midway value. Finding the middle requires adding the smallest and greatest values together, then dividing the result by two.Let us find the mean of the data set :
mean = (4 + 5 + 6 + 7 + 8) ÷ 5 = 30÷ 5 = 6
Median = 6 middle value.

Roxanne claims that all linear equations represent proportional relationships. Which statement explains whether Roxanne is correct?
A Yes, because all linear equations have graphs that are straight lines.
B No, because not all linear equations have graphs that pass through the origin.
C Yes, because all proportional relationships can be expressed as linear equations.
D No, because not all proportional relationships can be expressed as linear equations.
Roxanne claims that all linear equations represent proportional relationships. So, this statement "Yes, because all linear equations have graphs that are straight lines." makes him correct.
When there is a proportionate relationship between two variables, the other variable changes at a consistent pace regardless of how the first variable changes, grows or shrinks. A constant ratio between the two variables can be thought of as the constant rate.
Equations, graphs, and tables that use proportions can be used to show proportional relationships. A broad structure is followed by the proportional relationship equation, which will be taught in this session. Straight lines are used to illustrate the graphs. The tables are sets of numbers that are always paired in the same ratio.

Suppose that kellogg believes that the average weight for a box of frosted flakes is 18 ounces. As part of a quality control effort, they sample 30 boxes and find that the mean of those 30 boxes is 18. 2 ounces. Historical records show that the standard deviation of the filling process is 0. 32 ounces. How likely is it for the sample mean to have been 18. 2 ounces or larger if the actual mean is 18 ounces and the standard deviation of the filling process is 0. 32 ounces? round your answer to four decimal places.
If the actual mean is 18 ounces, there is a 0.0003 chance that the sample mean was 18.2 ounces or more.
Given that 18 ounces are what Kellogg estimates to be the typical weight of a box of Frosted Flaked. The average weight of the 30 cartons they sampled was 18.2 ounces. According to past data, the filling procedure's standard deviation is 0.32 ounces.
Let Y be a box weights random variable.
μ = 18 ounces
SD = 0.32 ounces
The sample size and mean are provided as,
Sample size (n) = 30
Sample mean (y) = 18.2
Y then follows roughly the standard deviation N(μ = 18, SD = 0.32)
Z score appears as:
[tex]z = \frac{\sqrt{n}(y-u)} {SD}[/tex]
where z is a normal standard variable having a mean of 0 and a standard deviation of 1.
Since sample size n is 30 and the standard deviation is given. y follows approximately Normal distribution
If the actual mean is 18 ounces, the likelihood that the sample mean will have been 18.2 ounces or more is given as,
[tex]P[Y \geq 18.2] = P [\frac{\sqrt{n(y - u)} }{SD} \geq \frac{\sqrt{30}(18.2- 18) }{0.32}\\ \\ =P [z\geq \frac{\sqrt{30}* 0.2 }{0.32}]\\ \\= P [z\geq \frac{1.0954}{0.32}]\\ \\=P [z\geq 3.4233]\\\\= 0.0003[/tex]
Therefore, if the actual mean is 18 ounces, there is a 0.0003 chance that the sample mean was 18.2 ounces or more.
