A) The data is symmetric and shows that he typically sent about 6 to 8 text messages per day.
B) The data is symmetric and shows that he sent 11 or 12 texts with the same frequency that he sent 1 or 2 texts.
C) The data is skewed and shows that he typically sent about 6 to 8 text messages per day.
D) The data is skewed and shows that he sent 11 or 12 texts with the same frequency that he sent 1 or 2 texts
*Check attachment for the dot plot referred to
Answer:
A. The data is symmetric and shows that he typically sent about 6 to 8 text messages per day
Step-by-step explanation:
Taking a look at the dot plot given in the attachment below, we can observe that most of the data set are concentrated in the middle of the dot plot than both ends of the dot plot. With this, we can infer that the distribution of the data is symmetric.
The dot plot also tells us that, 6 and 8 text messages have more frequency than any other data set on the dot plot. This also suggests that Reza usually sends 6 to 8 messages in a day.
Therefore, the statement that is true about the dot plot is:
"A. The data is symmetric and shows that he typically sent about 6 to 8 text messages per day"

Which expression has the same value as Negative 18 divided by (negative 9)? Negative 18 divided by 2 Negative 12 divided by (negative 3) Negative 10 divided by 5 Negative 8 divided by (negative 4) (for brainliest)
Answer: -8/-4
Step-by-step explanation:
When a negative integer gets divided my another negative integer, it results in a positive number. This means that we can eliminate all the negative symbols in this problem
18/9 = 2
Now all is left to determine which other expression is equivalent to 2
In the expression -10 / 5, since there is only one negative symbol, the postulate for negative number division states that two negative integers makes a positive number, and there is one negative integer and one positive whole number.
18/2 = 9 = incorrect
12/3 = 4 = incorrect
-10/5 = -2 = incorrect
8/4 = 2 = correct
So the expression -8/-4 is equivalent to the expression -18/-9

I need to know the volume of this droplet in cubic meters!
Answer:
There are 100³ = 1000000 cubic cm in one cubic meter so the answer is 0.1 / 1000000 = 1 / 10000000 = 0.0000001 cubic meters.
Write the quadratic function in f(x)= a(x-h)^2+k form whose graph is shown.
f(x)=
Answer:
f(x) = - (x - 2)² + 2
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, 2 ), thus
y = a(x - 2)² + 2
To find a substitute the point (0, - 2) into the equation
- 2 = a(- 2)² + 2 ( subtract 2 from both sides )
- 4 = 4a ( divide both sides by 4 )
a = - 1
Thus
f(x) = - (x - 2)² + 2
1 Dentro de seis años tendré el doble de la edad que tenía hace cuatro años. ¿Qué edad tendré dentro de nueve años?
Answer:
23 años
Step-by-step explanation:
Para resolver la situación, consideremos que x es la edad de la persona. Sabemos que dentro de seis años esta tendrá el doble de la edad que tenía hace cuatro años. La edad dentro de 6 años se puede expresar como x+6 y esto será igual al doble de la edad que tenía hace cuatro años, lo que se puede expresar como 2(x-4). De acuerdo a esto:
x+6=2(x-4)
x+6=2x-8
6+8=2x-x
x=14
Ahora que sabemos que la edad de la persona es 14 años, le sumamos 9 y esto da como resultado 23 y esta es la edad que la persona tendrá en 9 años.

Write the set { 1, 3, 7, 15, 31, 63 } in set builder form
Answer:
{ x : x = 2^n -1 , n ∈ N}
Where N is the set of natural numbers
Step-by-step explanation:
Mathematically, we can rewrite each term in the set as follows;
1 = 2^1 - 1
3 = 2^2 -1
7 = 2^3 -1
15 = 2^4-1
31 = 2^5-1
63 = 2^6 -1
so we can conclude that the nth term is 2^n -1
So writing this in set builder notation, we have;
{ x : x = 2^n -1 , n ∈ N}
Where N is the set of natural numbers
study the diagram of circle K where JL and LM are tangent to circle K at points J and M respectively. Also JL=3x+10 and ML =7x-6
Answer:
22
Step-by-step explanation:
The answer is 22. You solve the equation 3x+10=7x-6 like so
3x+10=7x-6
-3 = -3
10= 4x-6
+6 +6
16=4x
x=4
You then plug in the value of x to the equation for LM.
7x-6 becomes 7*4-6 which is 22.

Answer:
x = 20
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent, that is
∠ A = ∠ D , thus
3x - 10 = 2x + 10 ( subtract 2x from both sides )
x - 10 = 10 ( add 10 to both sides )
x = 20

Assume m<22=35. Find the measure of all of the other angles in the figure given line L and line P are parallel.
PLEASE HELP!!! ASAP!!!
(Picture included)
Answer:
m∠1 = 145°
m∠3 = 35°
m∠4 = 145°
m∠5 = 145°
m∠6 = 35°
m∠7 = 35°
m∠8 = 145°
Step-by-step explanation:
In the picture attached,
line 'm' and line 'l' are the parallel lines and another line intersects these lines is a transverse.
m∠2 = 35°
Since ∠1 and ∠2 are supplementary angles,
m∠1 + m∠2 = 180°
m∠1 + 35° = 180°
m∠1 = 180° - 35°
m∠1 = 145°
∠1 ≅ ∠4 [Vertical angles]
m∠1 = m∠4 = 145°
∠2 ≅ ∠3 [Vertical angles]
m∠2 = m∠3 = 35°
∠3 ≅ ∠6 [Interior alternate angles]
m∠3 = m∠6 = 35°
Similarly, ∠4 ≅ ∠5 [Interior alternate angles]
m∠4 = m∠5 = 145°
∠6 ≅ ∠7 [Vertical angles]
m∠6 = m∠7 = 35°
Plzzzzzzzz! A suitcase lock has a code 4 symbols long. The symbols on the lock are a star, a square, a circle, a triangle, a line, and a pentagon. What is the probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice? Enter your answer as a fraction in simplest form.
Answer:
[tex]\dfrac{1}{30}[/tex]
Step-by-step explanation:
6 symbols and 4-symbol code so number of combinations wich doesn't contain the same symbol twice would be:
6•5•4•3 = 360
If code starts with a star followed by triangle that means only one posibility for first two symbols and code doesn't containing the same symbol twice means that left 4 symbols for next two.
So number of combinations of code starting with a star followed by triangle and doesn't containing the same symbol twice will be:
1•1•4•3 = 12
The probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice:
[tex]\dfrac{1\cdot1\cdot4\cdot3}{6\cdot5\cdot4\cdot3}=\dfrac{1\cdot1}{6\cdot5}=\dfrac{1}{30}[/tex]

Answer:
B. p > 12.80(160) + 8235.
Step-by-step explanation:
Since he wants to make a profit, the price he will need to receive for his crop will have to exceed his costs. So, the equation would use the > sign rather than the >= sign.
He harvests crops for $12.80 per acre, with 160 acres. That would be 12.80(160).
He is spending $8235, which adds to the costs of harvesting.
So, the answer will be B. p > 12.80(160) + 8235.

Answer:
The correct option is option (3) 4 ÷ 25.
Step-by-step explanation:
The expression in terms of m and n is:
[tex]F(m,n)=[\frac{2m^{-1}n^{5}}{3m^{0}n^{4}}]^{2}[/tex]
Exponent rule of division:
[tex]a^{x}\div a^{y}=a^{x-y}[/tex]

If 2^2.322 = 5 then what does 2^5.322 equal? Explain how you found your answer.
Answer:
40.002
Step-by-step explanation:
[tex]2^{5.322}[/tex] is 2 to the power of 5.322. Only way to find the exact decimal is to calculate in a calculator. When we do so we should get 40.002 as our answer.
The question says:
'If 2^2.322 = 5 then what does 2^5.322 equal? Explain how you found your answer. '
So we have to use the fact that 2^2.322 = 5, in order to work out what 2^5.322 equals
_______________________________________________
Remember the following indices rule:
a^m times a^n = a^(m+n)
So first we have to use the indice rule to split apart 2^2.322:
[tex]2^{2.322}=2^{2+0.322}=2^2\times2^{0.322}=4\times2^{0.322}[/tex]
Now we can substitute this into the original equation, and work out the approximate value for [tex]2^{0.322}[/tex]:
[tex]2^{2.322} = 5[/tex]
[tex]4\times2^{0.322}=5[/tex]
[tex]2^{0.322}=\frac{5}{4} =1.25[/tex]
Now lets use the indices rule again to split apart 2^5.322:
[tex]2^{5.322} = 2^{5+0.322}=2^5\times2^{0.322}= 32\times2^{0.322}[/tex]
From the previous equation, we worked out that [tex]2^{0.322} = 1.25[/tex]
Therefore:
[tex]2^{5.322} = 32 \times 1.25 = 40[/tex]

Answer:
D.(-4,-8) and(2,4)
Step-by-step explanation:
y=-2x
y=x²-8
this means that the two equations are equal because they both add up to y
thus; x²-8=-2x
formulae=Ax²+bx+c=0
x²+2x-8=0
find two numbers which multiplied will give you x² and when added will give you 2x that is x and x
x²+x+x-8=0
x(x+1)+1(x-8)=0
(x+1)(x-8)=0
1)x+1=0. x= -1
further explanation on answers1)y=-2x
y=-2(-1)=2
y=2
2)y=x²-8
y=1²-8= -8
y= -8
note*this means that the answer should have both 2 and -8 thus d is the answer
