Jake asked students, "How many hours do you sleep each night?".
Three students said 7.
Two students said 8.
4 students said 9.
1 student said 10.
We have to describe how he can display the data in a dot plot.
What is a dot plot?Whenever we have to arrange data in a dot plot, they are stacked in a column over a category.
We have,
3 students = 7 hours.
2 students = 8 hours.
4 students = 9 hours.
1 student = 10 hours.

How many protons, neutrons and electrons are in an atom with an atomic 5 points
number of 20 and an atomic mass of 40?*
20 protons, 20 electrons, 20 neutrons
20 protons, 20 electrons, 40 neutrons
20 protons, 10 electrons, 20 neutrons
Answer:
By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons.

Answer:
I think it may be 120 cm
Step-by-step explanation:
A F is 13 using pythagorean theorem on triangle CED and applying the hypotenuse length to A F.
ABC is similar to triangle CED and is dilated by a factor of 3 so the base is 36.
using pythagorean theorem on triangle ABC gets the hypotenuse length of 39 which can be applied to FE
add all the values together
39 + 13 + 15 + 36 +12 +5 = 120

Angles α and β are angles in standard position such that: α terminates in Quadrant I and sinα = 3/5 β terminates in Quadrant III and tanβ = 5/12 . Find sin(α - β).
Answer:
-16/65
Step-by-step explanation:
Given sinα = 3/5 in quadrant 1;
Since sinα = opp/hyp
opp = 3
hyp = 5
adj^2 = hyp^2 - opp^2
adj^2 = 5^2 = 3^2
adj^2 = 25-9
adj^2 = 16
adj = 4
Since all the trig identity are positive in Quadrant 1, hence;
cosα = adj/hyp = 4/5
Similarly, if tanβ = 5/12 in Quadrant III,
According to trig identity
tan theta = opp/adj
opp = 5
adj = 12
hyp^2 = opp^2+adj^2
hyp^2 = 5^2+12^2
hyp^2 = 25+144
hyp^2 = 169
hyp = 13
Since only tan is positive in Quadrant III, then;
sinβ = -5/13
cosβ = -12/13
Get the required expression;
sin(α - β) = sinαcosβ - cosαsinβ
Substitute the given values
sin(α - β) = 3/5(-12/13) - 4/5(-5/13)
sin(α - β)= -36/65 + 20/65
sin(α - β) = -16/65
Hence the value of sin(α - β) is -16/65
Three tanks are capable of holding 361,841, and 901 of the greatest vessel winch can be used to fill each one of them on exact number of time
Answer:
Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.
Step-by-step explanation:
Three tanks are capable of holding [tex]361,841,901[/tex]
To find which tank can be used to fill each one of them an exact number of time, find [tex]HCF(361,841,901)[/tex]
[tex]361=19^2\\841=29^2\\901=17(53)[/tex]
Therefore,
[tex]HCF(361,841,901)=1[/tex]
So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Stefan sells Jin a bicycle for $127 and a helmet for $17.The total cost for Jin is 120% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally?How much money did he make by selling the bicycle and helmet to Jin?
Answer:
Stefan spent $120 originally
He made $24 dollars by selling the bicycle and helmet to Jin
Step-by-step explanation:
First, find the total cost:
127 + 17
= 144
To find the original cost, divide this by 1.2
144/1.2
= 120
So, Stefan spent $120 originally.
Now, find how much he made by subtracting 120 from 144:
144 - 120
= 24
So, he made $24 dollars by selling the bicycle and helmet to Jin.
Grace drew a triangle. Its sides were 6 mm. 7 mm and 11 mm.
It has one obtuse and two acute angles.
Complete the sentence to describe the triangle Grace drew.
Answer:
That would be an obtuse-scalene triangle.
Step-by-step explanation:
It is scalene because none of the sides are congruent. This means that none of the angles or sides are the same.

eve plays basketball. she makes 4 free throws for every 3 free throws that she misses. if she missed 24 free throws at her last practice, how many free throws did she make?
Answer:
She made 32 free throw shots.
Step-by-step explanation:
Based on the given information, one can form the general equation;
[tex]\frac{made}{missed}[/tex]
Substitute in the given values;
[tex]\frac{4}{3}[/tex]
Assuming that the rates at which this proportion exists is constant, and one knows the number she missed, but not the number she made then one can say;
[tex]\frac{made}{missed}= \frac{4}{3} = \frac{made}{24}[/tex]
Solve the proportion using cross products;
[tex]\frac{4}{3}=\frac{made}{24}\\\\\\(4)(24)=(3)(made)\\\\96=3made[/tex]
Inverse operations,
[tex]96=3made\\/3\\\\32=made[/tex]
Answer:
32 free throws

Step-by-step explanation:
The definition of a Plane is "In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far."
It couldn't be a Ray or a Line Segment because a Ray has 1 end point, and a Line Segment has 2.
It also couldn't be a Line because a Line is only 1 dimensional.
The answer has to be Plane.

Write a polynomial function in standard form with zeros at 5, -4, and 1.
Answer:
f(x) = x³ - 2x² - 19x + 20
Step-by-step explanation:
Given a polynomial with zeros x = a, x = b then the corresponding factors are
(x - a)(x - b) and the polynomial is then the product of the factors
Given zeros x = 5, x = - 4, x = 1 , then
(x - 5), (x + 4) and (x - 1) are the factors, then
f(x) = (x - 5)(x + 4)(x - 1) ← expand the first pair of factors using FOIL
= (x² - x - 20)(x - 1) ← distribute
= x³ - x² - 20x - x² + x + 20 ← collect like terms
= x³ - 2x² - 19x + 20
