men versus women: the average 20- to 29-year-old man is 69.9 inches tall, with a standard deviation of 3.0 inches, while the average 20- to 29-year-old woman is 64.1 inches tall, with standard deviation of 3.8 inches. a. find the z scores for a 67-inch- man and a 62-inch woman.
The z-scores for a 67-inch- man and a 62-inch woman are -0.9667 and -0.5526, respectively.
The z-score is a numerical measurement used in statistics to determine the sample data value's relationship to the mean of a group of values, measured in terms of standard deviation from the mean. It is measured as the difference of the sample data value and the sample mean over the standard deviation, such that
z-score = (x – μ) / σ
where x = sample data value
μ = mean
σ = standard deviation
For a 67-inch- man, use the formula to solve for the z-score.
x = 67
μ = 69.9
σ = 3.0
z-score = (x – μ) / σ
z-score = (67 - 69.9) / 3.0
z-score = -0.9667
Do the same for a 62-inch- man, use the formula to solve for the z-score.
x = 62
μ = 64.1
σ = 3.8
z-score = (x – μ) / σ
z-score = (62 - 64.1) / 3.8
z-score = -0.5526

What is Range ?
When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.
Currently, the function is
f(x) = 7 x 4^x
Suppose,
y = f(x) = 7 x 4^x.
=> y = 7 x 4^x
Hence,
lny = ln (7 x 4^x).
We obtain using the logarithm equation
Hence,
ln y = ln7 + ln 4^x.
= ln y = ln7 + x ln4 .
Hence,
y equals e^(ln7 + x ln4).
=> y = e^ln7.e^(xln4) (xln4)
Using the exponential formula, we obtain
=> y = 7xln4
Consequently, y=f(x)=7.x.ln4
To determine function f's value (x)
7.x.ln7 = 0
As a result, For all possible values of x (x€R). To date,

The number of time Easton's song was played on commercials is 10 times.
The number of time Easton's song was played during a movie is 4 times.
How many times was the song played in commercials and during movies?The first step is to form a system of equations:
40c + 110m = 840 equation 1
c - m = 6
c = 6 + m equation 2
Where:
c = number of times the songs was played in commercials.m = number of times the songs was played in moviesThe system of equations would be solved using the substitution method.
Substitute for c in equation 1 using equation 2
40(6 + m) + 110m = 840
240 + 40m + 110m = 840
40m + 110m = 840 - 240
150m = 600
m = 600 / 150
m = 4

Part B: Write the equation for Tunnel B in standard form and determine the conic section. Show your work.
Part C: Determine the maximum height of each tunnel. Is the truck able to pass through either tunnel without damage? If so, which tunnel(s) and why? Show your work.
The tunnel A will be damaged and truck can pass through tunnel B.

What is the standard form of parabola equation?The general equation of a parabola is: y = a(x-h)² + k or x = a(y-k)² +h, where (h, k) denotes the vertex. The standard equation of a regular parabola is y²= = 4ax.
Part A: x²+y²+30x+56=0
Add 15² on both the sides of a equation
That is, x²+30x+15²+y²=-56+15²
⇒ (x+15)²+y²=169
⇒ (x+15)²+y²=13²
Divide 13² on both the sides of the equation
⇒ (x+15)²/13² + y²/13² =1
Part B:
x²-30x+16y-95=0
Now, x²-30x+16y=95
Add 15² on both the sides of a equation
That is, x²-30x+15²+16y=95+15²
⇒ (x-15)²=320-16y
⇒ (x-15)²=16(20-y)
Part C:
Maximum height:
A: 13 feet
B: 20 feet
Width = 8 feet
A: x+15=8/2=4 y=12.37<13.5
B: x-15=8/2=4 y=19>13.5

I'll give you all 65 points that I have if you tell me how to do it because I want to understand the topic. thank you
Width of the box is the dimension which gives the gives maximum value.
Width of the box = 9 cm
Length of the box = 9 cm
Given,
The perimeter of the rectangular bottom of the box = 36 cm
The height of the box = 4 cm
We have to find the dimension which gives maximum value.
Volume = lwh
Perimeter = 2(l + w)
36 = 2l + 2w
l = (36 - 2w)/2
l = 18 - w
Now,
Volume = length × width × height
V = (18 - w) × w × 4
V = 72w - 4w²
Lets find w by using w = -b/2a
That is,
w = -72/2(-4) = -72/-8 = 9
That is,
Width of the box is 9 cm and it is the dimension which gives the maximum value.

<3 thx
Answer:
-6.4, -5 1/2, -5, and -2 6/4.
Step-by-step explanation:
Arranging these negative values in order from least to greatest may be tricky if you are not familiar with your integer rules and operations. However, if you seem to understand, even a little, this way may be helpful to you.
All you need to know is this. positive and negative are opposites. Thus, if, for example, +2 is greater than +1 in positives, then -2 is less than -1 in negatives. So, in other words, think about it this way when you see a negative number, but you are used to positive numbers, just assume that the biggest number on the positive side is the smallest number on the negative side.
Therefore, if we were to use this method, we would result in -6.4, -5 1/2, -5, and -2 6/4. Since it would be the opposite in positives.

What are linear equations?A linear equation is an algebraic equation of the form y=mx+b that only contains a constant and a first-order (linear) component, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where y and x are the variables. Ax+By=C is the accepted form for two-variable linear equations. Finding both intercepts of an equation in this form is rather simple (x and y). If an equation has the formula y=mx+b, with m denoting the slope and b the y-intercept, it is said to be linear. The point-slope form, standard form, and slope-intercept form are the three primary types of linear equations.
As given
ages are consecutive even integers
Victoria > Tyee
So
Victoria's age = x
Tyee's age = x + 2
x(x + 2) = 80
= x² + 2x - 80

The graph of the linear equation 4x - y = 8, with two points on the line is shown in the image attached below.
How to Graph a Linear Equation?If we know the slope, m, of the linear equation, which is the rise of the line over the run of the line, and also know the y-intercept value, b, we can graph a linear equation such that the slope of the line would be the value of m, and the point where the line intercepts the y-axis would be the value of b in the linear equation that is represented as y = mx + b.
Given the linear equation, 4x - y = 8, we can rewrite this in slope-intercept form as y = mx + b:
4x - y = 8
-y = -4x + 8 [subtraction property of equality]
y = 4x - 8 [division property of equality]
The slope, m, is 4, while the graph of the linear equation must intercept the y-axis at y = -8, because the y-intercept of the linear equation is b = -8.
Thus, the graph of 4x - y = 8 is shown below.

suppose m<7 = 96 find m<2 and m< 4
Answer:
Answer down below!
Step-by-step explanation:
If we draw this out, we already know that m<7 = 96
Using what we already know, we can figure out the rest
m<6 also equals 96 because m<7 and m<6 are verticle angles
m<3 also equals 96 because m<6 and m<3 are opposite interior angles
m<2 also equals 96 because m<3 and m<2 are verticle angles
Now, to find m<4, simply subtract 96 from 180. That should give you 84
Thus, m<2 = 96 and m<4 = 84
