To calculate the number of pounds of meat required to feed diners do the following:<span> for fish fillets divide the number to be served by 3.5.
</span>
Meat to be served = fish fillet
Amount of stock = 86 lb.
How many customers can be served fish? the answer will be d. 301 consumers,
86*3.5=301
I hope this helps!
The chi-square test is appropriate to analyze the primary efficacy endpoint in this study
The chi-square test is a valid statistical hypothesis test when the test statistic is chi-square distributed under the null hypothesis. Specifically, Pearson's chi-square test and its variants. Used to compare observed and expected results. The purpose of this test is to determine whether differences between observed and expected data are due to chance or to relationships between the variables being examined.
A chi-square formula is a statistical formula for comparing two or more sets of statistical data. It is used for data consisting of variables that span different categories and is denoted by χ2. The chi-square formula is χ2 = ∑(Oi – Ei)2/Ei, where Oi = observed (actual) and Ei = expected.

Answer:-2/3
Step-by-step explanation:the problem is asking for the slope of (0,2) and(3,0). The formula for this problem is y2-y1 over x2-x1. And if your writing this formula down write it like a fraction with y on top and x on bottom. (x,y) (x2,y2). You take the 0 from the second set and the 2 from the first set and subtract them to get -2. Then you take the 3 from the sea d set and the 0 from the first set and you subtract them to get 3. That’s how you get the answer of -2/3.
Answer:
Option A is correct
3.33 ft wide should the metal piece be.
Step-by-step explanation:
Area of rectangle(A) is given by:
.....[1]
l is the length and w is the width of the rectangle respectively.
As per the statement:
One more rectangular-shaped piece of metal siding needs to be cut to cover the exterior of a pole barn. The area of the piece is 30 ft²
⇒A = 30 ft²
It is also given that the length is 1 less than 3 times the width
⇒
ft
Substitute the given values in [1] we have;
Using distributive property: 
then;
We can write this as:
Factorize this equation:
Split the middle term we have;
⇒
⇒
By zero product property we have;
and w+3 = 0
Since, w cannot be negative;
so,
ft
Therefore, to the nearest hundredth of a foot, 3.33 ft wide should the metal piece be.
