the correct question is
<span>The product of two consecutive even integers is 120. Find the integers
let
x-----------> first even integer
x+2-------> second consecutive even integer
we know that
x*(x+2)=120-------> x</span>²+2x-120=0
<span>
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=10
therefore
</span>first even integer is 10
second consecutive even integer is (10+2)----> 12
<span>
the answer is
10 and 12

Answer:
The given statement is false.
Step-by-step explanation:
We are given the following in the question:
95% confidence interval: (4.53,5.18)
Sample mean, = 4.85 seconds
Sample size, n = 20
Alpha, α = 0.05
Sample standard deviation, σ = 1.47 seconds
Degree of freedom = n - 1 = 19
95% Confidence interval:
Putting the values, we get,
Thus, the calculated confidence interval is different from the given confidence interval.
Hence, the given statement is false.
The length of AT = cos 66°*12.5. option B is the correct answer
The trigonometric ratio cosine is used to connect the angle between the neighboring leg and the hypotenuse of a right triangle.
From the question, we have,
cos 66° = AT/12.5
AT = cos 66°*12.5
The length of AT = cos 66°*12.5
Divide:
Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
