A pizza shop charges $9.50 for a pizza, plus $1.90 for each topping.
If the total charge for a pizza is dependent on the base price of the pizza plus the number of toppings ordered, what is the value of y at the y-intercept of the line representing this situation?
Answers
The value of y at the y-intercept for the given situation, representing the cost of a pizza without any toppings, is $9.50.
The value of y at the y-intercept represents the cost of a pizza without any toppings. When we graph the cost of the pizza as a function of the number of toppings, the y-intercept occurs when the number of toppings is zero (meaning no toppings were added).
Since the pizza shop charges $9.50 for a pizza without toppings, this is the value of y at the y-intercept. We can represent this relationship with a linear equation y = mx + b, where m is the slope (the cost per topping) and b is the y-intercept (the base price of the pizza). In this case, m is $1.90 and b is $9.50, so the equation would be y = 1.90x + 9.50. Therefore, the y-intercept is $9.50.
Why are percents used to compare ratios when the wholes are different
Answers
The percent is used to compare the ratios when the wholes are different because it gives simple calculation.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The percent's are used to compare ratios when the wholes are different.
Now,
Let two ratios are,
⇒ 19/25 and 17/20
So, For compare we can find the percent of that ratios and simply by comparison we get the large and small ratio as;
⇒ 19/25 = 0.76 = 76%
⇒ 17/20 = 0.85 = 85%
Thus, The percent of ratio 17/20 is more than the percent of ratio 19/25.
So, The percent's are used to compare ratios when the wholes are different because it gives simple calculation and not to make denominator same.

In the Numbers Game, a state lottery, four numbers are drawn with replacement from an urn containing balls numbered 0-9, inclusive. Find the probability that a ticket holder has the indicated winning ticket.
The first two digits in exact order.
Answers
Thus, number of ways in which four numbers will be drawn from an urn containing balls numbered 0-9, inclusive is given by [tex]10^4=10,000[/tex]
The number of ways in which a ticket holder will have the first two digits in the correct order is the same as the number of ways in which two numbers will be drawn from the urn containing balls numbered 0-9, inclusive and is given by [tex]10^2=100[/tex]
Therefore, the probability that a ticket holder has the first two digits in exact order is given by [tex] \frac{100}{10,000} = \frac{1}{100} =0.01[/tex]
Final answer:
The probability of winning the indicated ticket in the Numbers Game is 1/100 or 0.01.
Explanation:
To find the probability of winning the indicated ticket in the Numbers Game, we will calculate the probability of the first two digits in exact order.
There are 10 numbers (0-9) to choose from in each digit, and since replacement is allowed, the probability of choosing the correct first number is 1/10. Similarly, the probability of choosing the correct second number is also 1/10.
Since the two selections are independent, we can multiply the probabilities together to find the probability of both selections being correct. Therefore, the probability of winning the indicated ticket is (1/10) * (1/10) = 1/100 or 0.01.

Answers
y = mx + b => y = (2/3)x - 2 (answer)
The equation of the line is [tex]\bold{y = \frac{2}{3}x-2}[/tex]
The correct answer is an option (C)
What is slope of the line?"It is the change in y coordinate with respect to the change in x coordinate."
What s y-intercept?"It is the point at which the line intersects the Y-axis."
What is slope-intercept form of line?"y = mx + c, where m is the slope and cis the y-intercept."
For given question,
A line has slope 2/3 and y–intercept -2.
So, m = [tex]\frac{2}{3}[/tex] and c = -2
Substitute these value in the slope-intercept form of line,

If m and n are integers is 6m^2+34n-18 an even integer?
Answers
For any integers m and n, [tex]\(6m^2 + 34n - 18\)[/tex] is always even Integer . One solution is [tex]\(m = 1, n = 2\)[/tex].
To determine if the expression [tex]\(6m^2 + 34n - 18\)[/tex] is an even integer for any integers m and n, let's analyze the terms.
The expression can be factored as [tex]\(2(3m^2 + 17n - 9)\).[/tex] Since 2 is a factor of the expression, it implies that the entire expression is even. Therefore, for any integers m and n, [tex]\(6m^2 + 34n - 18\)[/tex] is an even integer.
Now, to find possible values for m and n that satisfy the condition, consider that [tex]\(3m^2 + 17n - 9\)[/tex] must be an integer. We can choose arbitrary values for m and n and verify that [tex]\(3m^2 + 17n - 9\)[/tex]is an integer. For example, let m = 1 and n = 2:
[tex]\[3(1)^2 + 17(2) - 9 = 3 + 34 - 9 = 28\][/tex]
Since 28 is an integer, m = 1 and n = 2 are valid solutions.
conclusion, any integers m and n will make [tex]\(6m^2 + 34n - 18\)[/tex]an even integer. One such solution is m = 1 and n = 2, and there are infinitely many other possible pairs of integers that satisfy this condition.

A single ball is drawn from an urn containing 6 balls numbered 1 through 6. Find the probability that the ball choosen is as follows.
An even-numbered ball or an odd-numbered ball
Answers
Final answer:
The probability of drawing an even-numbered ball or an odd-numbered ball from the urn is 1.
Explanation:
To find the probability of drawing an even-numbered ball or an odd-numbered ball from an urn containing 6 balls numbered 1 through 6, we need to determine the total number of favorable outcomes and divide it by the total number of possible outcomes.
The total number of possible outcomes is 6, as there are 6 balls in the urn.
The favorable outcomes are the even-numbered balls (2, 4, 6) and the odd-numbered balls (1, 3, 5), which is a total of 6 balls.
Therefore, the probability of drawing an even-numbered ball or an odd-numbered ball is 6/6, which simplifies to 1.

a class donated $3.5 in nickels and dimes. In all there were 45 coins. how many were there of each
Answers
So, 45 coins times the value of 5 cents would then be $2.25.
So that means we are 1.25 dollars short of 3.50 dollars.
If the dime is worth 5 cents more then the nickel is, we can just divide 1.25 by 5 cents to see how many extra 5 cents we need.
1.25/0.05 = 25
So therefore there were 25 dimes, and through that we can tell there were 20 nickels.

How to find the inverse of h(x) = 3/ -x - 2 List steps.
Answers
First, you would have to switch the domain and range. In other words, swap x and y:
h(x) = 3/ -x-2
y = 3/ -x-2
x = 3/ -y-2
Then, when you have this, simply solve for y:
x = 3/-y-2
x (-y-2) = 3/-y-2 (-y-2)
x(-y-2) /x= 3 /x
-y-2 = 3/x
-y = 3/x + 2
y = -3/x -2
So the inverse would be
h⁻¹(x)= -3/x -2

Find the z-scores that bound the middle 74% of the area under the standard normal curve.
Answers
The P values, the z-scores are approximately: z score (left) = -2.22 and z score (right) = 1.13.
We are given that;
The area middle= 74%
Now,
We need to find the z-scores that bound the middle 74% of the area under the standard normal curve.
Since 74% of the middle area is bounded, this means that there is 13% on the left side and another 13% on the right side.
P (left) = 0.13 and P (right) = 1 - 0.13 = 0.87. At these P values, the z-scores are approximately: z score (left) = -2.22 and z score (right) = 1.13

Explanation:To find the z-scores that bound the middle 74% of the area under the standard normal curve, we need to find the z-scores that bound 13% on each tail of the curve (100% - 74% = 26%, divided by 2). Using the z-table, we can find the z-scores for these tail areas:
The z-score for the lower tail area of 13% is approximately -1.04The z-score for the upper tail area of 13% is approximately 1.04Therefore, the z-scores that bound the middle 74% of the area under the standard normal curve are -1.04 and 1.04.
