The amount of fish needed to be served is 294 lbs
How to determine the amount of fish needed?From the question, we have the following parameters that can be used in our computation:
Meat to be served: 3.5 pounds fish fillet
Number of guests: 84
The amount of fish needed is calculated using the following equation
Amount of fish = Number of guests x Meat to be served
Substitute the known values in the above equation, so, we have the following representation
Amount of fish = 84 * 3.5
Evaluate the products
Amount of fish = 294
Hence, the amount needed is 294 pounds

A school paid $248 for new basketballs and soccer balls. The number of basketballs purchased was 6 less than 3 times the number of soccer balls purchased. Basketballs cost $28 each and soccer balls cost $20 each. If b represents the number of basketballs and s represents the number of soccer balls, which system of equations best describes this situation?
Answer: D
Step-by-step explanation:
248 = 28x + 20y
x = 3y - 6

Kayla has $10 in a savings account. The interest rate is 5% per year and is not compounded. How much will she have in 2 years? Use formula i=p*r*t, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years
This is a question of Simple Interest. The simple interest is given by the formula:
[tex]I=P\cdot R\cdot T[/tex]That is:
Interest = Principal * Rate * Time
From the question, we have:
P = $10
R = 5% ---> 5/100 = 0.05
T = 2 years
Then, we have that the interest is (without units):
[tex]I=10\cdot0.05\cdot2\Rightarrow I=1[/tex]Therefore, the interest is $1.
However, Kayla will have in two years this interest plus the starting amount, that is:
$10 + $1 = $11.
Hence, Kayla will have $11 in two years in her savings account.

Complete the two-way frequency table below, which shows the relationship between students who enroll in advanced algebra and physics in
particular high school. From a sample of 40 students, it is found that 29 are taking algebra, 14 are taking physics, and 5 are enrolled in both. How
many students are enrolled in either algebra physics?
By making use of Set Theory, we calculate that a total of 38 students are enrolled in either physics or algebra.
Number of students taking algebra n(A)= 29
Number of students taking physics n(B)= 14
Number of students taking both subjects n(A∩B)= 5
So, the number of students taking either physics or algebra will be the union of sets i.e. n(A∪B)
The union of two sets is a set containing all elements that are in A or in B (possibly both).
As we know,
n(A∪B) = n(A) + n(B) - n(A∩B)
n(A∪B) = 29 + 14 - 5
n(A∪B) = 38
Therefore, A total of 38 students are enrolled in either physics or algebra.

The mean of a data set can be greater than any of the data sets
True or false and explain your reason.
The mean of a data set can be greater than any of the data sets is True.
The average is basically a model of the dataset. The most frequently occurring value. However, the mean value is often not one of the actual values observed in the dataset. The median can be larger or smaller than the mean of the distribution. So the given statement is wrong.
The mean is affected by outliers that do not influence the mean. Therefore, when the average distribution of data is skewed to the left, the mean is often less than the median. When the distribution is skewed to the right, the mean is often greater than the median. No matter what value we add to the set, the mean, median, and mode will shift by that amount but the range and the IQR will remain the same. The same will be true if we subtract an amount from every data point in the set.

Graph h(x) = 38(0.51)x. What is the constant percent rate of change of f(x) with respect to x? Does the graph show growth or decay?
49% growth
49% decay
51% growth
51% decay
Answer:
Step-by-step explanation:
This is decay, the rate of change is 49%
hope this helps!
The correct rate of change is B)49% decay.
What constant rate of change ?
A rate of change is constant when, at any given point along the function, the ratio of the output to the input remains constant. The slope is another name for the rate of change that is constant. A linear function's rate of change will be constant.
Here the given function is ,
=> h(x)=38(0.51)x.
For any exponential function in which the base is less than 1, it will be an exponential decay situation.
In this problem, the base is 0.51.
Then,The amount that the base is less than 1 ( i.e. 1 - base) . It represents the rate of change in decimal ,
=> 1-0.51 = 0.49
Converting into percentage => 0.49 *100 = 49%
Therefore the correct option is B) 49% decay.

The minimum number of tiles will be 122 that Imane needs to cover the floor.
How to Convert Square Feet to Square Inches?Multiply the area by the conversion ratio to convert a square foot measurement to a square inch measurement. Because one square foot equals 144 square inches, you may use the following easy formula to convert:
square inches = square feet × 144
The area in square inches is equal to the square feet multiplied by 144.
The floor she wants to cover has an area of 216 square feet.
The required area in square inches is :
216 × 144 = 31,104 sq in
Each tile covers an area of 256 square inches.
The minimum number of tiles = 31,104 sq in / 256 sq in
