in a carnival drawing,a green ticket wins $1,a yellow ticket wins $5,and a blue ticket wins $10. There are 100 green tickets, 25 yellow tickets and 5 blue tickets. in simplest form, what are the odds in favor of winning $5 or more?
The odds in favor of winning $5 or more at the carnival are 3 to 10.
To determine the odds in favor of winning $5 or more at the carnival, we need to consider the number of tickets that win $5 or more and the total number of tickets.
Identify the tickets that win $5 or more: Yellow tickets win $5 and Blue tickets win $10.
Count the number of these tickets:
Yellow tickets: 25
Blue tickets: 5
Total tickets that win $5 or more:
25 + 5 = 30
Total number of tickets:
100 + 25 + 5 = 130
Odds in favor of winning $5 or more is the ratio of favorable outcomes to unfavorable outcomes:
Winning tickets: 30
Non-winning tickets:
130 - 30 = 100
Simplified odds:
30 to 100 = 3 to 10
Therefore, the odds in favor of winning $5 or more are 3 to 10.
The odds in favor of winning $5 or more in a carnival drawing are 3 : 10. So, the correct option is (B).
To determine the odds in favor of winning $5 or more in a carnival drawing, observe the number of tickets for each prize and calculate the favorable outcomes.
Here are the ticket counts:
Green ticket ($1): 100 ticketsYellow ticket ($5): 25 ticketsBlue ticket ($10): 5 ticketsFirst, calculate the total number of tickets:⇒ 100 (green) + 25 (yellow) + 5 (blue) = 130 tickets
Next, calculate the number of tickets that win $5 or more:⇒ 25 (yellow) + 5 (blue) = 30 tickets
The remaining tickets are the losing tickets or those winning less than $5 (green):⇒ 130 (total) - 30 = 100 tickets
Therefore, the odds in favor of winning $5 or more are 30:100, which simplifies to 3:10. This converts to the following odds as a ratio:
So, the correct option is (B) 3:10.

Suppose z=x^2*sin(y), x=2s^2−4t^2, y=4st.
A. Use the chain rule to find ∂z/∂s and ∂z/∂t as functions of x, y, s and t.
Use the chain rule of differentiation to calculate ∂z/∂s and ∂z/∂t. Start by differentiating the functions z with respect to x and y, then differentiate the functions x and y with respect to s and t. Finally, plug the derived values into the chain rule formula to get the expressions for ∂z/∂s and ∂z/∂t.
Explanation:To solve the problem, we will need to apply the chain rule in order to calculate ∂z/∂s and ∂z/∂t. The chain rule is used in calculus to differentiate a function that has other functions inside of it.
We will differentiate z which is the function of x and y, and x and y themselves are functions of s and t.
The steps are as follows:
Calculate ∂z/∂x and ∂z/∂y by differentiating z with respect to x and y. Calculate ∂x/∂s, ∂x/∂t, ∂y/∂s and ∂y/∂t by differentiating x and y with respect to s and t.Use these calculated values to calculate ∂z/∂s and ∂z/∂t by applying the chain rule formula.
The chain rule formula is:
∂z/∂s = ∂z/∂x * ∂x/∂s + ∂z/∂y * ∂y/∂s
and
∂z/∂t = ∂z/∂x * ∂x/∂t + ∂z/∂y * ∂y/∂t.
This will give you the final expressions for ∂z/∂s and ∂z/∂t as functions of x, y, s, t.

The following list shows the items and prices for a restaurant order. Calculate the total amount if there is 7.5% tax and the customer leaves a 15% gratuity.
1 appetizer: $8.99
2 entrees: $14.99 each
1 entree: $12.99
3 drinks: $1.99 each
a. $70.96
b. $71.62
c. $75.31
d. $75.97
The first thing we are going to do to find the total cost of the meal before tax:
Total cost before tax = $8.99 + 2($14.99) + $12.99 + 3($1.99)
Total cost before tax = $8.99 + $29.98 + 12.99 + $5.97
Total cost before tax = $57.93
Regarding the 15% gratuity, remember that the unofficial rule for tipping at restaurants is to tip according to the actual value of the meal and not the tax, so we calculate the value of the tip first, and then we add it to the total at the end of our calculations.
Tip = 15%($57.93) = $8.69
Now, lets calculate the tax
Tax = 7.5%($57.93) = $4.34
Finally, we can calculate the total cost of the meal
Total cost = cost before tax + tip + tax
Total cost = $57.93 + $8.69 + $4.34 = $70.96
We can conclude that the correct answer is a. $70.96
Answer:
$70.96
Step-by-step explanation:
Cost of 1 appetizer = $8.99
Cost of 1 entrees= $14.99
Cost of 2 entrees= [tex]14.99 \times 2 = 29.98[/tex]
Cost of 1 entree: $12.99
Cost of 3 drinks = 1.99 \times 3 =5.97
Total cost before tax = $8.99 + $29.98 + 12.99 + $5.97
Total cost before tax = $57.93
there is 7.5% tax
So, tax =[tex]7.5 \% \times 57.93 = \frac{7.5}{100} \times 57.93 =4.34[/tex]
The customer leaves a 15% gratuity.
Gratuity=[tex]15 \% \times 57.93 = \frac{15}{100} \times 57.93 =8.69[/tex]
So, Total cost including tax and gratuity = $57.93 + $8.69 + $4.34 = $70.96
So, Option A is true

Nellie is buying bird seed to put in her bird feeders. She uses about 10 pounds of bird seed each week, but has room to store any extra that she purchases.The bird seed comes in 3 different sizes as given below: 3.5 pounds for $2.52 7.5 pounds for $5.40 11 pounds for $7.92 Nellie is trying to be a smart shopper and get the best deal on the bird seed. Which size bag of bird seed should Nellie buy?
All the bird seed bags Nellie is considering have the same cost per pound ($0.72). She should choose based on her weekly usage and storage preference. Any size will be cost-effective.
To determine the best deal on bird seed, Nellie needs to calculate the unit price for each option. The unit price is the price per pound of bird seed.
For the 3.5-pound bag:
[tex]\[ \text{Unit price} = \frac{\$2.52}{3.5 \text{ pounds}} \approx \$0.72/\text{pound} \]\\For the 7.5-pound bag:\[ \text{Unit price} = \frac{\$5.40}{7.5 \text{ pounds}} = \$0.72/\text{pound} \]For the 11-pound bag:\[ \text{Unit price} = \frac{\$7.92}{11 \text{ pounds}} \approx \$0.72/\text{pound} \][/tex]
Since all three options have the same unit price of approximately $0.72 per pound, Nellie should choose the size that offers her the most pounds of bird seed for the best value, as he has anyway room for storing extra purchase. Here, can choose to buy any of them.

what is the largest perfect square of 45? ...?
The largest perfect square less than or equal to 45 is 36, which is the square of 6. Squaring numbers less than 7 shows that 36 is the perfect square closest to, but not exceeding 45.
Explanation:The largest perfect square that is less than or equal to 45 is the result of the greatest integer squared that does not exceed 45. To find this, you would look for the highest whole number whose square is less than or equal to 45. The numbers less than 45 are 1, 2, 3, ..., and so on. Squaring these: 12=1, 22=4, 32=9, 42=16, 52=25, 62=36. The next number, 7, squared is 49, which is greater than 45. Therefore, 62=36 is the largest perfect square less than or equal to 45. This concept is essential when simplifying square roots or in problems dealing with areas of squares.The range of which function includes -4?
A. y=sqrt(x)-5
B. y=sqrt(x)+5
C. y=sqrt(x+5)
D. y=sqrt(x-5)
Answer: The correct answer is A.
Step-by-step explanation:
Range is defined as the set of 'y' values for which the function is defined.
The graph of [tex]y=\sqrt{x}[/tex] passes through the origin and lies in the first quadrant and in the shape of half parabola. The image is attached below.
The alteration in the 'x' term will transform the graph in the x-direction. In order to find the range we will consider the y-values only. So, we can neglect option C and D.
When we add some constant 'C' in the function, then the graph will shift upward by C-units.
When we subtract some constant 'C' in the function, then the graph will shift downward by C-units.
Therefore, the graph of [tex]y=\sqrt{x}-5[/tex] starts with the point (0,-5) and hence, the graph will lie above this point. The image of the graph is attached below.
As, the range of the function is [tex]y\in {-5,\infty}[/tex], it means that -4 is also included in this range.
Hence, the correct option is A.
The correct option where the range includes -4 is y = sqrt(x) - 5. Other options do not produce negative values in their ranges. Hence, Option A is the correct answer.
To determine which function's range includes -4, we will analyze each option:
Option A: y = sqrt(x) - 5Based on the above analysis, the correct answer is Option A: y = sqrt(x) - 5.
In the diagram below, AB is parallel to CD. What is the value of x?
The correct answer is: Option (D) x = 72°
Explanation:
When two lines are crossed by another line, the angles in matching corners are called corresponding angles. When the two lines are parallel, the corresponding angles are equal.
Here in this case, the two lines are "AB" and "CD", and both are parallel and are crossed by the line; therefore, the corresponding angles will be the same.
Since the first corresponding angle is 72°, the second angle x will be 72° as well. The correct answer is: x = 72° Option (D).
