Answer:
27 28 29
Step-by-step explanation:
Let the first be n , and if they are consecutive then the next two numbers are n+1 and n+2.
n+(n+1)+(n+2)=84.
3n+3=84.
⇒3n=81.
⇒n=27.
Hence numbers are n,n+1,n+2→27,28 and 29
which surveys illustrate an example of qualitative data? check all that apply.the time, in minutes, it took students to finish their examsthe eye color of students involved in after-school activitiesthe characteristics of different types of birdsthe scores on the last examthe weights of different books
Qualitative data include the eye color of students involved in after-school activities and the characteristics of various types of birds.
What do we mean by Qualitative data?Qualitative data are those that cannot be expressed numerically and cannot be measured.So,
The time it took students to finish their exams in minutes can be measured numerically, so it is quantitative data.Because the eye color of students involved in after-school activities cannot be measured, the data is qualitative.The characteristics of various types of birds cannot be measured numerically - thus, it is qualitative data.The last exam score can be measured and expressed numerically, so it is quantitative data.The weights of various books can also be measured, resulting in quantitative data.Therefore, qualitative data include the eye color of students participating in after-school activities as well as the characteristics of various bird species.

y = A cos[B(x-C)] + D, where
A = amplitude,
period = 2π / |B|
C = Phase shift
D = vertical shift
Amplitude = (Max value - Min value) / 2
Amplitude = 80 - 40 / 2
Amplitude = 20
24 = 2π / |B|
B = π / 12
vertical shift = Max value + Min value / 2
D = 80 + 40 / 2
D = 60
Since the temp. is min. at t = 0, we will use negative cosine.
H(t) = -20 cos(π t/ 12) + 60

Answer:
A
Step-by-step explanation:
x² + 7x + 12 = 0
consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)
the factors are + 3 and + 4 , since
3 × 4 = + 12 and 3 + 4 = + 7 , then
(x + 3)(x + 4) = 0
equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 4 = 0 ⇒ x = - 4
Find the measure of the indicated angle.
Answer:
Angle FDG is 42°
Step-by-step explanation:
the whole angle GDE is an obtuse angle (greater than 90° but less than 180°), but a line is drawn at the middle to split it into 2.Each will be an acute angle.This means our answer must be acute.Mathematically ,
x+86=128
X=128-86
X=42°
to be sure,when an obtuse angle is split into two angles,it becomes 2 acute angles.
What is the vertex of the quadratic function below?
y=x² +12%-7
O A. (-6,-43)
OB. (-6,-29)
O C. (6,3)
OD. (6,29)
Answer:
A
Step-by-step explanation:
assuming you meant y = x² + 12x - 7 , then
given a quadratic in standard form
y = ax² + bx + c (a ≠ 0 )
the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 12x - 7 ← is in standard form
with a = 1 , b = 12 , then x- coordinate of vertex is
x = - [tex]\frac{12}{2}[/tex] = - 6
substitute x = - 6 into the equation for corresponding y- coordinate
y = (- 6)² + 12(- 6) - 7
= 36 - 72 - 7
= - 43
vertex = (- 6, - 43 )

Geela has 20 litres of yoghurt that she wants to put into pots containing 1-litres each.
How pots can she fill ?
We get that the number of pots that can be filled are 20 pots.
We are given that:
The total amount of yoghurt with Geela = 20 liters.
The amount of yoghurt in 1 pot = 1 liter
Now, we need to find the number of pots that can be filled.
So, we will do this by using division.
We get that:
Number of pots that can be filled. = 20 / 1
Number of pots that can be filled. = 20 pots
Therefore, we get that the number of pots that can be filled are 20 pots.

The Springfield zoo is breeding gorillas. They have 3 gorillas which can mate and give birth. After the first year there are 7 gorillas. After the second year there are 11 gorillas. If the gorillas continue to increase at the same rate, how long will it take for the Springfield zoo to have 35 gorillas?
Using a linear function, it will take 8 years for the Springfield zoo to have 35 gorillas.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, the parameters are given as follows:
m = 4, b = 3.
Hence the number of gorillas after x years is given by:
G(x) = 3 + 4x.
It will have 35 gorillas when:
G(x) = 35.
Hence:
3 + 4x = 35.
4x = 32.
x = 32/4
x = 8.
It will take 8 years for the Springfield zoo to have 35 gorillas.

gloria has a lunch account in the school cafeteria. the balance, f(x), in her account can be represented by the function f(x)
The given function is an equation describing the expenses of Gloria at her school cafeteria: She has 40 dollars in total and spends 2.75 dollars for each meal; 40 - 2.75x is the new function of linear equation.
What is a linear equation?Linear equations refer to the equations that involve two or more variables in the form of "ax + b".
Now,
Given: The expenses of Gloria at her school cafeteria is given by the linear equation: 40 - 1.5x, where x = number of meals purchased.
To find: The relation when 1.50 changes to 2.75.
Finding:
AS given in the question, 40 - 1.50(x) represents the money spent by Gloria in her school cafeteria, where:40 represents the total money she has.1.50 represents the money spent on each meal by her.x represents the number of meals.If 1.50 changes to 2.75, it means that the cost of her meal increased from 1.50 to 2.75, by 1.25 dollars. Further, it means that her expenses have increased now and that her total money will now be spent earlier than what would have been spent if she spent 1.50 dollars on each meal.The new relation will be given by the linear equation: 40 - 2.75x.Hence, The given function is an equation describing the expenses of Gloria at her school cafeteria: She has 40 dollars in total and spends 2.75 dollars for each meal; 40 - 2.75x is the new function of linear equation.

26 pregnant women who were getting prenatal care and had either acknowledged marijuana usage or had urine samples test positive for marijuana underwent semi-structured interviews. During interviews, it was determined where women got their information on the dangers of prenatal marijuana use and how valuable they thought it was. Two coders independently coded the interview data, iteratively improved the codes, and looked over the transcripts for themes.
The most frequently used illegal substance during pregnancy is marijuana. Little is known about how pregnant marijuana users learn about and comprehend perinatal marijuana use. To further understand their information-seeking behaviors and opinions of the value of material accessible about perinatal marijuana use, we performed a qualitative study among pregnant marijuana users.

Using similar triangles, it is found that the measure of angle B is of 74º.
What are similar triangles?Similar triangles are triangles that have the same angle measures, and whose side lengths are proportional.
In this problem, the triangle ABC was translated, resulting in triangle A'B'C'. A translation does not change the measures of the angles, hence their angles are given as follows:
80º, 26º and B.
The sum of the internal angles of a triangle is of 180º, hence:
80 + 26 + B = 180
B = 74º.
The measure of angle B is of 74º.

undefined slope?
what’s the equation
Answer:
x = 4
Step-by-step explanation:
You want the equation of the vertical line through (4, 6).
Undefined slopeSlope is the ratio of rise to run for a line. When the "run" is zero, that ratio becomes undefined. The "run" will be zero for any rise when the line is vertical.
EquationThe equation of such a line has the form ...
x = c . . . . . for some constant c
In order for this equation to be satisfied when (x, y) = (4, 6), the value of the constant must match the x-coordinate of the point.
The equation is x = 4.

Step-by-step explanation:
3, 15, 75...

15/3=5
Every term multiplied by 5 is the next term. Hence, the equation for this sequence can be expressed as:
y=3*[tex]5^{x-1}[/tex] ==> y is the term when x is the term number and 3 is the first number in the sequence
Now let's solve for the 10th term:

We are told that f(x) is the price with the $20 coupon applied, and
g(x) is the price with the 15% discount applied. Thus;
1) An expression for f(x) is;
f(x) = (1 - 0.25)x = 0.75x
f(x) = 0.75x
2) An expression for g(x) is;
g(x) = (1 - 0.2)x = 0.8x
g(x) = 0.8x
3) An expression for (f o g)(x) is;
(f o g)(x) = f(g(x)) = 0.75(0.8x) = 0.6x
(f o g)(x) = 0.6x
