Answer:
The margin of error = 0.037
Step-by-step explanation:
Explanation:-
Given that the mean of the Population(μ) = 2.38
Given that the standard deviation of the Population(σ) = 0.59
Given sample size 'n' = 950
Level of significance = 0.05
The critical value( Z₀.₀₅) = 1 .96
The margin of error is determined by
[tex]M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }[/tex]
[tex]M.E = \frac{1.96 (0.59)}{\sqrt{950} }[/tex]
M.E = 0.037
Final answer:-
The margin of error = 0.037

the actual distance between two cities is 135 km. The map scale is 1cm: 100 km. Find the map distance.
someone pls helpp !!!
Answer:
1.35cm
Step-by-step explanation:
Given the scale of the map
1cm = 100km
For 135km;
x cm = 135 km
Divide both equations
1/x = 100/135
100x = 135
x = 135/100
x = 1.35cm
Hence the map distance will be 1.35cm
Which notation describes {1, 2, 3}
first three natural numbers
First, three natural numbers notation describes {1, 2, 3}.
What is set notation?In mathematics, set notation is essentially a list of numbers, things, or results. Curly brackets, often known as braces, are used for set notation. The items included between brackets are referred to as elements of a set and are not required to be in any particular order.
Given, a set {1, 2, 3}
Since a set notation used to represent the elements of a set is the curly brackets { }. An example of a set is A = {a, b, c, d}. Here the set is represented with a capital letter, and its elements are denoted by small letters.
These given number best fit in the category of natural numbers.
Therefore, First, the notation for three natural numbers shows {1, 2, 3}.

If a number is odd, then it has a remainder of 1 when divided by 2.
Which is the conclusion of the conditional
Answer:
A number is odd
Step-by-step explanation:
Odd numbers are not completely divisible by 2.
What is the importance of knowing divisibility rules?The importance of knowing divisibility rules is that we can determine whether a number is divisible by certain numbers generally from 1 to 20 or not without actually dividing.
A number is divisible by 2 if it's unit digit is divisible by 2.
A number is divisible by 3 if the sum of the digits is divisible by 3.
A number is divisible by 4 if the last two digits is divisible by 4.
A number is divisible by 5 if its unit digit is 5 or 0.
A number is divisible by 9 if the sum of the digits is divisible by 9.
A number is divisible by 10 if its unit digit is 0.
Given, If a number is odd, then it has a remainder of 1 when divided by 2.
So the numbers which are not completely divisible by 2 have a remainder and are odd numbers and numbers which are completely divisible by 2 with no remainder are even numbers.

++

0 1 2 3
Answer:
The median is 5cm.
Step-by-step explanation:
Median is one of the 3 famous measures of central tendency.
The others are: mean & mode.
A median is the middle figure in an array of figures which are lined up from lowest value to highest value.
Here, the variable we're working with is Amount of rainfall in Vietnam cities (in centimeters).
The data shows 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 0cm, 1cm, 2cm, 3cm
We start by arranging them in order of value; from lowest to highest:
0cm, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm
There are 11 values in total.
Since 11 is an odd number, it is easy to find the median in this set of values.
Five values to the left and five values to the right; the median is 5cm!

If 15 larger paper clips were laid end to end to make a length of 17 7/8 inches, is each paper clip larger or smaller than one inch? Explain how you know.
Answer:
Larger than [tex]1\ \text{inch}[/tex]
Step-by-step explanation:
The total lenght of [tex]15[/tex] paper clips is [tex]17\dfrac{7}{8}=\dfrac{143}{8}\ \text{inches}[/tex]
In order to find the length of [tex]1[/tex] paper clip we divide the total length of the paper clips by [tex]15[/tex]. So,
[tex]\dfrac{\dfrac{143}{8}}{15}\\ =\dfrac{143}{8}\times\dfrac{1}{15}\\ =\dfrac{143}{120}\\ =1\dfrac{23}{120}=1.1917\ \text{inches}[/tex]
So, one paper clip is [tex]1.1917\ \text{inches}[/tex] long which is larger than [tex]1\ \text{inch}[/tex].

A function is shown: f(x) = (1.07)x What does the function represent? Exponential growth of 7% Exponential decay of 7% Exponential growth of 93% Exponential decay of 93%
Answer:
Exponential growth of 7%
Step-by-step explanation:
We are given the function:
A function is shown: f(x) = (1.07)^x
We can compare this to a formula of Exponential Growth
y = a(1 + r)^x
Hence:
1 + r = 1.07
r = 1.07 - 1
r = 0.07
Converting to percy
0.07 × 100
= 7%
Therefore, the function represents Exponential growth of 7%
Answer:
It is
Exponential decay of 93%

Answer:
1) x=30 degrees
2)y=20 degrees
1) 3x+2x+1x= 6x (a triangle is normally 180 degrees) 180 divide 6=30 (this is because 6 Xs make up the triangle)
2) 2y+5y+5+y+15= 8y+20, (since a triangle has 180 degrees) 8y+20=180 (-20 from both sides) 8y=160, 160 divide 8=20

Find the parallel and perpendicular slope of a line if linear equation is 7y=20(x-3) Slope (Parallel) is ____ Slope (Perpendicular) is _____
Answer:
The parallel line has slope [tex]\frac{20}{7}[/tex]
The perpendicular line has slope [tex]-\frac{7}{20}[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope.
Parallel lines:
Parallel lines have the same slope.
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
In this question:
We have the following line:
[tex]7y = 20(x-3)[/tex]
Placing it in the general format
[tex]7y = 20x - 60[/tex]
[tex]y = \frac{20x}{7} - \frac{60}{7}[/tex]
So this line has slope [tex]\frac{20}{7}[/tex]
Parallel line:
Same slope, so the parallel line has slope [tex]\frac{20}{7}[/tex]
Perpendicular line:
Multiplication of the slopes is -1. So
[tex]\frac{20m}{7} = -1[/tex]
[tex]20m = -7[/tex]
[tex]m = -\frac{7}{20}[/tex]
The perpendicular line has slope [tex]-\frac{7}{20}[/tex]
