Find the cube root of the numbers
Step-by-step explanation:
(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)
Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.
We know that (n - 2) + n + (n + 2) = 78,
so 3n = 78, and n = 78/3 = 26.
Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.

Answer:
The margin of error is<em> 0.22</em>
Step-by-step explanation:
Mathematically, the margin of error at the given confidence interval can be calculated using the formula below;
Margin of error = × s/√n
where is the t-value at the given confidence interval, s is the standard deviation and n is the sample size
= 1.96 (From t-distribution table)
s = 2.5 inches
n = 500
MOE = 1.96 × 2.5/
MOE = 1.96 × 2.5/22.36
MOE = 0.22
Use the first and lay set of x,y values.
Rate of change is change in y/ change in x:
7-10 / 5- -1 = -3/6 = -1/2
The answer is A.-1/2
In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
