the lifespans of lizards in a particular zoo are normally distributed. the average lizard lives 3.13.13, point, 1 years; the standard deviation is 0.60.60, point, 6 years. use the empirical rule (68-95-99.7\%)(68−95−99.7%)left parenthesis, 68, minus, 95, minus, 99, point, 7, percent, right parenthesis to estimate the probability of a lizard living between 2.52.52, point, 5 and 4.34.34, point, 3 years.
The probability of a lizard living for more than 2.5 years is 16%.
What is defined as the normally distributed?The proper term for just a probability bell curve is the normal distribution.The mean of a normal distribution is zero, and the standard deviation is one. It has a skew of 0 and a kurtosis of 3.Although all symmetrical distributions are normal, not all normal distributions are symmetrical.The average lifespan of a lizard is 3.1 years, with a standard deviation of 0.6 years.
Average lizard u = 3.1,
standard deviation σ = 0.6
To calculate the likelihood of a lizard living for more than 2.5 years;
p(X<2.5)
μ + aσ = 2.5
3.1 + a(0.6) = 2.5
a(0.6) = −0.6
a = −1
To calculate the probability, apply the empirical rule.
The total area = 100% (since total probability always is 1)
Area from μ to ∞ = p(X > μ) = 50%
Area between (μ−σ) and (μ+σ) = 68%
Area between (μ−σ) and μ is p((μ−σ) < X < μ) =34%
Thus,
p(X< (μ−σ)) = 1 − (p((μ−σ) < X < μ) + p(X > μ))
= 1 − (0.34 + 0.5)
p(X< (μ−σ)) = 0.16
Therefore, the probability that a lizard will live longer than 2.5 years 16%.

Given the function defined in the table below, find the average rate of change, in
simplest form, of the function over the interval 4 ≤x≤ 8.
Hence the average rate of change, in simplest form is -10 .
What is average rate of change?
The average rate at which one item is changing in relation to another is known as the average rate of change. A method that computes the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.Examples of average rates of change include: 80 km/h is the average speed of a bus. In a lake, fish population growth occurs at a pace of 100 per week.Using the coordinate points from the table ( 4,53) ( 8, 13 )
Substitute the coordinate into the expression
Average rate of change = y₂ - y₁/x₂ - x₁
= 13 - 53/8 - 4

The linear equation in point-slope form of a line with a slope of 23 and point (3,-2) is y = 23x - 71.
How to determine the equation of a line from a point and slope?The slope intercept formula is expressed as;
y = mx + b
Where m is the slope and b is the y-intercept.
Given the data in the question;
Slope m = 23Point: (3,-2)
x = 3y = -2Equation of line = ?First, use the the formula for the equation of line to determine the y-intercept 'b'.
y = mx + b
Plug in slope m = 23 and point (3,-2)
-2 = (23)3 + b
-2 = 69 + b
b = -2 - 69
b = -71
Now that we have both the slope m ( 23 ) and y-intercept b ( -71 ), plug these values into y = mx + b to find the linear equation.
y = mx + b
y = 23x + (-71)
y = 23x - 71
Therefore, the equation of the line is y = 23x - 71.

Find the slope of the line that passes through the following points: (4,-2) and (-4,-4)
The value of of slope of is 1/4.
How to calculate the value of the slope?It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope of lines in a coordinate plane can aid in anticipating whether the lines are parallel, perpendicular, or none at all without actually using a compass.
Any two distinct places along the line can be used to determine the slope of any line. When two different places on a line are considered, the slope of a line formula compares the "vertical change" to the "horizontal change" in each case. The difference between the line's y and x coordinate changes is known as the slope of the line. Net changes in the y and x coordinates are as follows: y = y and x = x.
m = [tex]y_{2} - y_{1} /x_{2} x_{1}[/tex]

Answer: yes, the value of x is 4 and angle HEB is 36 degrees
Step-by-step explanation:
1a. Find the value of angle CEB
Given that line segment AB and line segment EC are perpendicular you know they are right angles and therefore are equal to 90 degrees
2a.set up an equation
After noticing that angle CEB is 90 degrees you know that angle HEB+CEH=90 degrees: 13x+9x+2
3a. Solve the equation
13x+9x+2=90
22x+2=90 | combine like terms
22x=88 | subtract 2 from both sides
x=4 | divide by 22 on both sides

To find on the interval: [9, 9 + h]
∵ Average rate of change of f(x) on interval (a,b) is
A = f(b) - f(a) / b - a
⇒ f(9) = 1 x 9 + 12 = 21
⇒ f(9 + h) = 9 +h + 12 = 21 + h
⇒ f(b) - f(a) = 21 + h - 21 = h

What is function ?The most common symbols for a function are the letters f, g, and h. A function's value at an element of its domain x is denoted by the notation f(x), and the numerical value obtained from the function evaluation at a specific input value is denoted by substituting that value for x. For instance, the value of f at x = 4 is denoted by the notation f(x) (4). When a function isn't given a name and is instead represented by the expression E, the value of the function at, say, x = 4 may be shown by the notation E|x=4.
Given that :f(x) = 2x + 10
f(x) = 2x + 10
