What is a statistical question and what is its purpose? Be sure to include the 3 characteristics. That makes it up.
Answer- and statistical question is a question that guides research by defining the population of a given topic and that anticipates variability in the collected data. The purpose of a statistical question is it is the first step of the statistical process. The 3 characteristics of a statistical question are allows for clear responses, includes a specific population, and anticipates variability of the data.
What does it mean for data to have variability as it refers to statistical questions? Give an example.
A statistical question has more than one possible answer
Example- how many chores do you have? Some people might say 5 or 2 or even 0. It just depends on the person's family.
Well a dot diagram is like this for example,
And a histogram is this,
Dot diagram uses dots and the histogram uses bars.
When would we use them? Well that I can explain, you can use the dot diagram to see what pets people have or even to see how many people scored how many points.
A histogram can be used for a concert. There would be like on the bottom, 0-6, 7-12, and so on. The bars show how many people from what age group are joining the concert.
Explain the difference between center and shape of a data set.
The center is the median and/ or mean of the data. The spread is the range of the data. And, the shape describes the type of graph.

The table shows the time Mario worked and the
amount of money he earned during two different
weeks. Based on the information in the table,
how much will Mario earn if he works 13 hours in
a week?
Answer:
$120.25
Step-by-step explanation:
How much Mario would earn in 13 hours = 13 x amount earned in an hour
Amount earned in an hour = total amount earned / total hours
83.25 / 9 = 9.25
111/ 12 = 9.25
9.25 x 13 = 120.25

Which number is the discriminant of a quadratic equation that has no solution?
1) 0
2) 36
3) -4
4) 5
Answer:
-4
Step-by-step explanation:
If the discriminant is negative there can be no real number solution because the square root of a negative number does not exist (in real numbers).
In the Quadratic Formula, if [tex]b^2-4ac[/tex] is negative, then you can't find [tex]\sqrt{b^2-4ac}[/tex].
Juan necesita para su coche verde 3dl y 75 ml de aceites,y para su coche azul 13cl y 5ml.¿Cuantos hl necesita en total? ¿Tendrá suficiente con una lata de medio litro?
Answer:
1. Juan necesita 0,0051 hl en total.
2. Juan no tendrá suficiente con una lata de medio litro.
Step-by-step explanation:
1. Para calcular el volumen total en hl, primero debemos convertir todas las unidades a hl.
Para el coche verde:
[tex] V_{1} = 3 dl*\frac{1 hl}{1000 dl} = 0,003 hl [/tex]
[tex] V_{2} = 75 ml*\frac{1 hl}{100000 ml} = 0,00075 hl [/tex]
Para el coche azul:
[tex] V_{3} = 13 cl*\frac{1 hl}{10000 cl} = 0,0013 hl [/tex]
[tex] V_{4} = 5 ml*\frac{1 hl}{100000 dl} = 0,00005 hl [/tex]
Ahora, para encontrar el volumen total debemos sumar todos los volúmenes anteriores:
[tex] V_{T} = V_{1} + V_{2} + V_{3} + V_{4} = 0,003 hl + 0,00075 hl + 0,0013 hl + 0,00005 hl = 0,0051 hl [/tex]
Por lo tanto, Juan necesita 0,0051 hl en total.
2. Luego, para saber si tendrá suficiente con una lata de medio litro, debemos convertir el volumen total de hl a l:
[tex] V_{T} = 0,0051 hl*\frac{100 l}{1 hl} = 0,51 l [/tex]
Entonces, dado que el volumen total es 0,51 litros Juan no tendrá suficiente con una lata de medio litro porque necesita cubrir 0,01 litros más.

Using words and equations, explain what you learned about exponents in this lesson so that someone who was absent could read what you wrote and understand the lesson. Consider using an example like 2^4 • 3^4 =6^4
I WILL MARK BRAINIEST FOR WHOEVER ANSWERS THE FASTEST
Answer:
Multiplication rule of exponents says [tex](xy)^n = x^n * y^n[/tex] hence, 2^4 • 3^4 =6^4
Step-by-step explanation:
As per the rule of exponents,
[tex](xy)^n = x^n * y^n[/tex]
If we go by the above equation, we can deduce that x is 2 and y is 3
Thus, 2^4 *3^4 can be written as [tex](2*3)^4 = 6^4[/tex]
Hence, 2^4 • 3^4 =6^4

Mary is building a rectangle enclosure for all her chickens. The length of the enclosure is 22.5m and the width is 13.2m. If she already has 30m of fencing, how much more does she need?
Answer:
41.4 meters
Step-by-step explanation:
22.5 + 13.2 = 35.7
35.7 × 2 = 71.4m (because of the other 2 sides of the rectangle)
71.4-30=41.4m

machine produces 195 bolts in 20 minutes. At the same rate, how many minutes would it take to produce 312 bolts?
Answer:
32
Step-by-step explanation:
There are two ways of doing this.
Frist, divide the amount of bolts by time. This will get you the bolts produced in 1 minute.
195/20
=
9.75
Now we know that 9.75 bolts are produced every 1 minute.
Lets divide the 312 bolts by the bolts produced per minute. This will give us the amount of minutes it takes to produce the 312 bolts.
312/9.75
=
32.
This is our answer.
Another way of doing thisis to divide the 20 minutes by 195, this will give you how long it takes to produce a single bolt.
20/195
=
0.1025
Now, just multpliy it by 312, and you get how long it takes to produce 312 bolts.
0.1025*312
=
32
And again, you get the answer.
Hope this helps! ;)

32 I guess

What is the domain of y = x + 1?
Answer:
[0, infinity
Step-by-step explanation:
It's essential to type "sqrt(x)" or "√x," which are vastly different from the linear function y = x + 1.
The domain of the square root function is [0, infinity).
Adding 1 to this merely shifts the entire graph up 1 unit.
So the domain of y = √x + 1 is the same as before: [0, infinity
A 30-foot ladder is set against the side of a house so that it reaches up 24 feet. If Elizabeth grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 21 ft.) Round to the nearest tenth of a foot.
Use the Pythagorean theorem to calculate the distance from the wall the ladder originally is:
x = sqrt(30^2 - 24^2)
x = sqrt(900-576)
x = sqrt(324)
x = 18
The ladder was originally 18 feet from the wall. Moving the ladder 3 feet further away makes the new distance 18 + 3 = 21 feet.
Now use the Pythagorean theorem again to find the new height of the ladder.
Height = sqrt(30^2 - 21^2)
Height = sqrt(900 - 441)
Height = sqrt(459)
Height = 21.42
Rounded to the nearest tenth = 21.4 feet.

On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 2) and goes through (1, 0.5).
Answer:
B, the second graph
Step-by-step explanation:
The function on a graph has to pass through the points (0, 4) and (2, 1), that's the one you should pick
By analyzing the given exponential function, we will see that the correct option is the third one.
How to find the graph of the given function?
The function is:
f(x) = 2*(1/2)^x
So, we have a value smaller than 1 and larger than zero with the exponent x. This means that for really small values of x, the outcome will be very large, while for large values of x, the outcome will tend to zero. So this is an exponential decay.
When evaluated in zero we have:
f(0) = 2*(1/2)^0 = 2
So it crosses through the point (0, 2).
And when evaluated in x = 1, we have:
f(1) = 2*(1/2)^1 = 1
Then it also passes through (1, 1).
Then the correct option is the third one:
"On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 2) and goes through (1, 1)."

Answer:
Yes
Step-by-step explanation:
12²=144
16²=256
20²=400
Since 144+256=400, 12, 16, and 20 can form a right triangle
By using Pythagoras theorem AB^2+BC^2=CA^2
