A middle school took all of its 6th grade students on a field trip to see a ballet. The students filled 1898 seats, which was 73% of the total number of seats in the theater. How many total seats were in the theater?
Answer:
x = 2600 seats.
Step-by-step explanation:
Let the total number of seats be x.
Given the following data;
Number of seats occupied = 1898 seats
Percentage = 73%
To find the total number of seats;
Translating the word problem into an algebraic equation, we have;
[tex] \frac {73}{100} * x = 1898 [/tex]
Cross-multiplying, we have;
[tex] 73x = 1898 * 100 [/tex]
[tex] 73x = 189800 [/tex]
[tex] x = \frac {189800}{73} [/tex]
x = 2600 seats.
Therefore, the total number of seats in the theater are 2600 seats.

30 = 2.5x
What is x equal to? Help please!
Answer:
x = 12
Step-by-step explanation:
30=2.5x for you to find the value of x divide both side by 2.5.
30 = 2.5x
2.5 2.5
12 = x
To check your answer, substitute the value of x.
30 = 2.5 (12)
30 = 30
If it is equal, your answer is correct!
x is equal to 12 in the given equation 30 = 2.5x.
To find the value of x in equation 30 = 2.5x, we can solve for x by isolating it on one side of the equation.
Given equation: 30 = 2.5x
To isolate x, we need to divide both sides of the equation by 2.5:
30/2.5 = (2.5x)/2.5
Simplifying this equation, we have:
12 = x
Therefore, x is equal to 12.
By dividing both sides of the equation by 2.5, we effectively cancel out the multiplication of x by 2.5, leaving us with the value of x. So, when 12 is substituted for x in the original equation, 2.5 times 12 equals 30, confirming that the value of x = 12 satisfies the equation.
Hence, x is equal to 12 in the given equation 30 = 2.5x.

⅚of the number of pupils in a class is 4 greater than three-quarters of the number in the class .find the number of pupils in the class
Answer:
48 pupils
Step-by-step explanation:
let the number of people in the class be x
⅚ of the number of pupils in a class is expressed as ⅚x
4 greater than three-quarters of the number in the class is expressed as 3/4x+4
Equating both expressions
⅚x = 3/4x + 4
5x/6 - 3x/4 = 4
(10x-9x)/12 = 4
x/12 = 4
x = 4*12
x = 48
Hence the number of pupils in the class is 48 pupils

Step-by-step explanation:
Given the trapezoid formula:
1/2(b1+b2/2)xH
We are given the numbers for the trapezoid:
0.3,0.9,1
To solve this here is what we are going to do.
1/2(0.9+0.3)x1
So add 0.9+0.3=1.2
Then Divide 1.2/2=0.6
So multiply 0.6 x 1=0.6

toby has already cycled 6 kilometers this year, plus he plans to cycle 14 kilometers during each trip to work. after 3 trips to work, how many kilometers will toby have cycled?
Answer:
48 kilometers
Step-by-step explanation:
If Toby has traveled to work 3 times, and each time he traveled 14 kilometers, to find out how many kilometers he's traveled total, all you have to do is multiply 14 x 3, which equals 42. To find out how many kilometers he's traveled in all this year, just add the amount of kilometers he has already traveled. (42+6)
A mug is 3/7 full. The mug contains 4/7 of a cup of water. Find the capacity of the mug.
Answer:
7/6 cups
Step-by-step explanation:
Mug is 2/7 full
Amount of water in the mug = 1/3 cup
Assume the full capacity of the mug = m
Then the current capacity of water in mug = (2/7) of m = (2/7)m
Current capacity of water in mug is equivalent to 1/3 cup of water
Hence,
(2/7)m = 1/3
2m/7 = 1/3
Cross multiply
(2m * 3) = 7 * 1
6m = 7
m = 7/6
m = 1 1/6 cups

Which line has a slope of 0?
y= -10
2y + 6x = 0
x= – 5
y=x+5
When the equation of any line reads "y = a number",
its graph will always be a horizontal line, meaning zero slope.
So the equation y = -10 has a slope of 0 which
means its a flat or horizontal line.

A random sample of 40 workers was selected from Company B and another random sample of 40 workers was selected from Company C. The proportion of workers from Company B who purchased coffee was
Complete question is;
On a given day, the proportion of workers from Company B who purchase a coffee from the company cafeteria is 0.62 and the proportion of workers from Company C who purchase a coffee from the company cafeteria is 0.71. A random sample of 40 workers was selected from Company B and another random sample of 40 workers was selected from Company C. The proportion of workers from Company B who purchased coffee was p^_B = 0.70 and the proportion of workers from Company C who purchased coffee was p^_C = 0.75.
What is the correct unit of measurement for the mean of the sampling distribution p^_B - p^_C?
A) Days
B) Dollars
C) Companies
D) Workers
E) There are no units associated with the mean of the sampling distribution
Answer:
E) There are no units associated with the mean of the sampling distribution
Step-by-step explanation:
We are given;
Population proportion for workers from Company B who purchase a coffee from the company cafeteria as 0.62
Population proportion for workers from Company C who purchase a coffee from the company cafeteria as 0.71
Now, we were told that a random sample of 40 each were selected from both company B & C and the sample proportion were;
p^_B = 0.70 and p^_C = 0.75
Now, this proportions don't have any units as it is based on a ratio of the number of people that purchased coffee to the number of people surveyed.
Thus we can conclude that p^_B - p^_C will not have any units associated with it.
The possible outcomes of the difference in proportions of the two samples
based on on the individual proportions are not associated with a unit.
The correct option for the unit of measure of the sampling distribution [tex]\hat p_B - \hat p_C[/tex] is E. There are no units associated with the mean of the sampling distribution.Reasons:
The given parameters are;
The proportion of workers of Company B who purchase coffee from the
Company B workers that purchase coffee from the cafeteria = 0.62
Company A workers that purchase coffee from the cafeteria = 0.71
Number of workers in the sample from Company B = 40
Number of workers in the sample from Company A = 40
Proportion of Company B workers who purchase coffee, [tex]\hat p_B[/tex] = 0.71
Proportion of Company C workers who purchase coffee, [tex]\hat p_C[/tex] = 0.75
Required:
The unit of the mean of the sampling distribution of [tex]\mathbf{\hat p_B - \hat p_C}[/tex]
Solution:
The proportion of the workers that purchase coffee is given by the ratio of the number of workers that purchase coffee to the number of workers in the sample.
Therefore;
[tex]\displaystyle \hat p = \mathbf{\frac{Coffee \ buying \ workers}{Total \ number \ of \ workers}}[/tex]
Given that the unit of the numerator and denominator are both workers,
that divide out, we have that the [tex]\mathbf{\hat p}[/tex], [tex]\mathbf{\hat p_B}[/tex], [tex]\mathbf{\hat p_C}[/tex] and therefore [tex]\hat p_B - \hat p_C[/tex] are not
associated with a unit.
Therefore;
The correct option is; E. There are no units associated with the mean of the sampling distribution.
