Answer:
Equation: y=8.5h+25 Answer: $50.50
Step-by-step explanation:
h= amount of hours
y=total cost
y=8.5h+25
She rented for 3 hours
y=8.5(3)+25
y=25.5+25
y=50.5
Chicken A: Standard deviation of A is 4.6 grams; 68% of the eggs fall between 50.9 grams and 60.1 grams.
Chicken B: Standard deviation of B is 4.9 grams; 68% of the eggs fall between 51.9 grams and 61.7 grams.
The difference between the mean weight of Chicken B’s eggs and the mean weight of Chicken A’s eggs to the nearest tenth is...?
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs to the nearest tenth is 1.8 grams.
A normaldistribution is a probability distribution that is symmetric around the mean, with most of the data points falling close to the mean and fewer data points falling farther away from it.
The shape of a normal distribution is often referred to as a bellcurve because when the distribution is graphed, the resulting curve resembles a bell
We have,
Since both datasets follow a normaldistribution, we can use the empirical rule (also known as the 68-95-99.7 rule) to find the mean weight of each chicken's eggs.
For Chicken A, we know that 68% of the eggs fall between 50.9 grams and 60.1 grams. This means that the mean weight of Chicken A's eggs is the average of these two values:
Mean of A = (50.9 + 60.1) / 2 = 55.0 grams
For Chicken B, we know that 68% of the eggs fall between 51.9 grams and 61.7 grams. This means that the mean weight of Chicken B's eggs is the average of these two values:
Mean of B = (51.9 + 61.7) / 2 = 56.8 grams
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs is:
Difference = Mean of B - Mean of A
= 56.8 - 55.0
= 1.8 grams
Therefore,
The difference between the meanweight of Chicken B's eggs and the mean weight of Chicken A's eggs to the nearest tenth is 1.8 grams.

O B. fx) = x^2
O C. f(x) = -4x^2
O D. f(x) = x2 + 3
f(x) = x² is the quadratic parent function, Option B is correct.
A relation is a function if it has only One y-value for each x-value.
A parent function is the simplest function that still satisfies the definition of a certain type of function.
The quadratic parent function is the basic form of a quadratic equation and is written as f(x) = x².
This equation has no constants, no x-intercepts, and a vertex located at the origin.
All other quadratic equations can be derived from this basic form.
f(x) = x²- 5, f(x) = -4x² and f(x) = x² + 3 are not the parent functions but these are derived function after applying some rules.
Hence, f(x) = x² is the quadratic parent function, Option B is correct.

Given the conversion rate of 1 gallon = 16 cups and that 1/2 cup of milk makes 12 muffins, you can make 32 batches of 12 muffins using one gallon of milk.
The subject we are dealing with here is Mathematics and it's about a practical application of ratios and conversions. The student wants to know how many batches of 12 muffins can be made using one gallon of milk, given that 1/2 cup of milk makes 12 muffins.
To solve this, we first need to understand the relationship between gallons and cups. Specifically, 1 gallon is equivalent to 16 cups. If 1/2 cup of milk makes 12 muffins, hence 1 gallon, or 16 cups, will make 2 batches/cup x 16 cups/gallon = 32 batches of muffins.
Therefore, one gallon of milk can be used to bake 32 batches of 12 muffins each.
