Answer:
The probability of getting someone in the 18-21 age bracket or someone who agreed to respond [tex]= 0.365[/tex]
Step-by-step explanation:
The counts are as follows
Age Group No of people contacted No of refusals Total
18-21 88 8 96
22-29 240 42 282
Total 328 50 378
The probability of getting some one in the age bracket of 18-21 or some one who refused to respond is
[tex]= \frac{96}{378} + \frac{50}{378} - \frac{8}{378} \\= \frac{96+50-8}{378} \\= \frac{138}{378} \\= 0.365[/tex]

Given;
The figure of a right angle triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given right angle triangle,
[tex]\cos (45^\circ)=\dfrac{7}{x}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{7}{x}[/tex] [tex][\because \cos (45^\circ)=\dfrac{1}{\sqrt{2}}][/tex]
On cross multiplication, we get
[tex]1\times x=7\times \sqrt{2}[/tex]
[tex]x=7\sqrt{2}[/tex]
Therefore, the value of x is [tex]7\sqrt{2}[/tex] units.

Can you find four examples that are true or a counterexample for the following statement?For every integer n, the value of n^2 + 1 is odd
Solving the expression, it is found a counterexample that when [tex]n = 1[/tex], [tex]n^2 + 1 = 2[/tex] is even.
----------------------
The expression given is:[tex]E(n) = n^2 + 1[/tex]
We want to test for every integer n, that E(n) is odd.----------------------
For n = 0:
[tex]E(0) = 0^2 + 1 = 0 + 1 = 1[/tex]
Odd number.
----------------------
For n = 1:
[tex]E(1) = 1^2 + 1 = 1 + 1 = 2[/tex]
Even, thus, this is the counterexample.

Graph the equation.
y= 5(x + 1)^2– 3
HELP!!!
Step-by-step explanation:
the answer is in the attachment
The graph of the function y= 5(x + 1)²– 3 is attached accordingly. See the description of the graph below.
The graph of y= 5(x + 1)²– 3The equation y = 5(x + 1)² - 3 represents a quadratic function.
The graph is a parabola with its vertex at (-1, -3). It opens upward since the coefficient of the squared term (x²) is positive.
The graph is vertically stretched by a factor of 5 compared to the standard quadratic function.
The x-coordinate of the vertex is -1, indicating a horizontal shift of 1 unit to the left from the standard quadratic.
