The table shows the proportional relationship between the number of tickets required per game at a carnival. Games 4 7 10 Tickets 20 35 50 Determine the constant of proportionality.
Correct answer will get brainiest
Answer:
Therefore, the constant of proportionality for the given proportional relationship is 5.
Step-by-step explanation:
To determine the constant of proportionality in the given proportional relationship, we can use the formula:
Constant of Proportionality = Tickets / Games
Let's plug in the values from the table:
For the first set of values (4 games and 20 tickets):
Constant of Proportionality = 20 / 4 = 5
For the second set of values (7 games and 35 tickets):
Constant of Proportionality = 35 / 7 = 5
For the third set of values (10 games and 50 tickets):
Constant of Proportionality = 50 / 10 = 5
In all three cases, the constant of proportionality is equal to 5.
Therefore, the constant of proportionality for the given proportional relationship is 5.

Assuming an average driving speed of 88 km/hr, how long will it take to drive from Toronto to buffalo (distance between Toronto and buffalo is 154km)
The distance it will take to drive from Toronto to buffalo (distance between Toronto and buffalo is 154km) is 1.75 hours.
We are given that;
distance = 154 km speed = 88 km/hr
Now,
we need to use the formula:
time = distance / speed
where time is in hours, distance is in kilometers, and speed is in kilometers per hour.
Plugging these values into the formula, we get:
time = 154 / 88 time ≈ 1.75
Therefore, by speed the answer will be 1.75 hours.

Seth is using the figure shown below to prove Pythagorean Theorem using triangle similarity:
In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC.
The figure shows triangle ABC with right angle at A and segment AD. Point D is on side BC.
Which of these could be a step to prove that BC2 = AB2 + AC2?
possible answers -
By the cross product property, AB2 = BC multiplied by BD.
By the cross product property, AC2 = BC multiplied by BD.
By the cross product property, AC2 = BC multiplied by AD.
By the cross product property, AB2 = BC multiplied by AD.
The correct step to prove that \(BC^2 = AB^2 + AC^2\) is:
By the cross product property, \(AC^2 = BC \cdot AD\).
To prove that \(BC^2 = AB^2 + AC^2\), we can use the triangle similarity and the Pythagorean theorem. Here's a step-by-step explanation:
Given triangle ABC with right angle at A and segment AD perpendicular to segment BC.
By triangle similarity, triangle ABD is similar to triangle ABC. This is because angle A is common, and angle BDA is a right angle (as AD is perpendicular to BC).
Using the proportionality of similar triangles, we can write the following ratio:
\($\frac{AB}{BC} = \frac{AD}{AB}$\)
Cross-multiplying, we get:
\($AB^2 = BC \cdot AD$\)
Similarly, using triangle similarity, triangle ACD is also similar to triangle ABC. This gives us:
\($\frac{AC}{BC} = \frac{AD}{AC}$\)
Cross-multiplying, we have:
\($AC^2 = BC \cdot AD$\)
Now, we can substitute the derived expressions into the original equation:
\($BC^2 = AB^2 + AC^2$\\$BC^2 = (BC \cdot AD) + (BC \cdot AD)$\\$BC^2 = 2 \cdot BC \cdot AD$\)
It was made possible by cross-product property.
Therefore, the correct step to prove that \(BC^2 = AB^2 + AC^2\) is:
By the cross product property, \(AC^2 = BC \cdot AD\).

Answer: Marian can pack 132 softballs in 11 boxes.
Step-by-step explanation:
Marian packed 60 bsoftballs in 5 boxes.
so, she packed (60÷5)=12 softballs in each box.
NOW, she can pack (12×11)=132 softballs in 11 boxes.
Answer:
Step-by-step explanation:
Marian can pack 132 softballs in 11 boxes. Hence option C is correct.
Here we can use the unitary method to solve this question, i.e.
Since we can fill 5 boxes with 60 softballs, that means a single box can contain 12 softballs.
Hence 11 boxes could contain, 11 x 12 = 132 softballs.
Hence, option C is the correct option.

Answer:

To calculate this, subtract the larger number from the smaller number to find the difference. 0.98 - 0.97 = 0.01, so the yellow button costs $0.01 more than the teal button.
I know you’re supposed to change the bounds and break up the integral, but for some reason, I can’t get the 44/3. Can someone explain how to solve this definite integral?
First, look for the zeroes of the integrand in the interval [0, 6] :
x² - 6x + 8 = (x - 4) (x - 2) = 0 ⇒ x = 2 and x = 4
Next, split up [0, 6] into sub-intervals starting at the zeroes we found. Then check the sign of x² - 6x + 8 for some test points in each sub-interval.
• For x in (0, 2), take x = 1. Then
x² - 6x + 8 = 1² - 6•1 + 8 = 3 > 0
so x² - 6x + 8 > 0 over this sub-interval.
• For x in (2, 4), take x = 3. Then
x² - 6x + 8 = 3² - 6•3 + 8 = -1 < 0
so x² - 6x + 8 < 0 over this sub-interval.
• For x in (4, 6), take x = 5. Then
x² - 6x + 8 = 5² - 6•5 + 8 = 3 > 0
so x² - 6x + 8 > 0 over this sub-interval.
Next, recall the definition of absolute value:
\(|x| = \begin{cases}x & \text{for }x \ge0 \\ -x & \text{for }x < 0\end{cases}\)
Then from our previous analysis, this definition tells us that
\(|x^2 - 6x + 8| = \begin{cases}x^2 - 6x + 8 & \text{for }0<x<2 \text{ or } 4<x<6 \\ - (x^2-6x+8) & \text{for }2<x<4\end{cases}\)
So, in the integral, we have
\(\displaystyle \int_0^6 |x^2-6x+8| \, dx = \left\{\int_0^2 - \int_2^4 + \int_4^6\right\} (x^2 - 6x + 8) \, dx\)
Then
\(\displaystyle \int_0^2 (x^2 - 6x + 8) \, dx = \left(\frac13 x^3 - 3x^2 + 8x\right) \bigg|_0^2 = \frac{20}3 - 0 = \frac{20}3\)
\(\displaystyle \int_2^4 (x^2 - 6x + 8) \, dx = \left(\frac13 x^3 - 3x^2 + 8x\right) \bigg|_2^4 = \frac{16}3 - \frac{20}3 = -\frac43\)
\(\displaystyle \int_4^6 (x^2 - 6x + 8) \, dx = \left(\frac13 x^3 - 3x^2 + 8x\right) \bigg|_4^6 = 12 - \frac{16}3 = \frac{20}3\)
and the overall integral would be
20/3 - (-4/3) + 20/3 = 44/3

Complete Question
Suppose the weight of Chipotle burritos follows a normal distribution with mean of 450 grams, and variance of 100 grams2 . Define a random variable to be the weight of a randomly chosen burrito.
(a) What is the probability that a Chipotle burrito weighs less than 445 grams? (3 points)
(b) 20% of Chipotle burritos weigh more than what weight
Answer:
a
\(P(X < 445 )= 0.3085\)
b
\(k = 458.42\)
Step-by-step explanation:
From question we are told that
The population mean is \(\mu = 450 \ g\)
The variance is \(var = 100 \ g^2\)
The consider weight is \(x = 445 \ g\)
The standard deviation is mathematically represented as
\(\sigma = \sqrt{var}\)
substituting values
\(\sigma = \sqrt{ 100}\)
\(\sigma = 10\)
Given that weight of Chipotle burritos follows a normal distribution the the probability that a Chipotle burrito weighs less than x grams is mathematically represented as
\(P(X < x ) = P ( \frac{X - \mu }{\sigma } < \frac{x - \mu }{\sigma } )\)
Where \(\frac{X - \mu }{\sigma }\) is equal to z (the standardized values of the random number X )
So
\(P(X < x ) = P (Z < \frac{x - \mu }{\sigma } )\)
substituting values
\(P(X < 445 ) = P (Z < \frac{445 - 450 }{10} )\)
\(P(X < 445 ) = P (Z <-0.5 )\)
Now from the normal distribution table the value for \(P (Z <-0.5 )\) is
\(P(X < 445 ) = P (Z <-0.5 ) = 0.3085\)
=> \(P(X < 445 )= 0.3085\)
Let the probability of the Chipotle burritos weighting more that k be 20% so
\(P(X > k ) = P ( \frac{X - \mu }{\sigma } > \frac{k - \mu }{\sigma } ) = 0.2\)
=> \(P (Z> \frac{k - \mu }{\sigma } ) = 0.2\)
=> \(P (Z> \frac{k - 450}{10 } ) = 0.2\)
From the normal distribution table the value of z for \(P (Z> \frac{k - \mu }{\sigma } ) = 0.2\) is
\(z = 0.8416\)
=> \(\frac{k - 450}{10 } = 0.8416\)
=> \(k = 458.42\)

What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
{m} is the slope of the line.
{c} is the {y} - intercept.
Given is a scatter plot as shown in the image.
We can write the equation of the line of best fit as -
{m} = (400 - 0/(60 - 40)
{m} = 400/20
{m} = 20
We can write the y - intercept as -
y = 20x + c
0 = 800 + c
c = - 800
So, the equation of the line of best fit is -
y = 20x - 800
For {y} = 5000, we can write -
5000 + 800 = 20x
5800 = 20x
x = 5800/20
x = 290
Therefore, to make the profit of $5000, the temperature should be 290 degrees Fahrenheit.
