Answer:
what question?...........
The accompanying bar graph shows the percentage of adults in a certain city who smoked cigarettes for selected years from 1970 through 2010.
The mathematical model p + x/2 = 33 describes the percentage, p, of adults who smoked cigarettes x years after 1970. Use this information to answer questions (a) and (b) below.
Does the mathematical model underestimate or overestimate the percentage of adults who smoked cigarettes in 2010? By how much? Select the correct choice below and fill in the corresponding answer box to complete your choice.
Using function concepts, we have that:
The actual percentage of smokers in 2010 was of 23%, while the estimated was of 13%, thus, the model underestimated the percentage by 10%.
-----------------------------
The function is:
[tex]p + \frac{x}{2} = 33[/tex]
In which
p is the percentage of smokers.x is the number of years after 1970.The percentage can be written as a function of the number of years, that is:
[tex]p(x) = 33 - \frac{x}{2}[/tex]
-----------------------------
2010 is 2010 - 1970 = 40 years after 1970, thus, the estimate of the percentage in 2010 is:
[tex]p(40) = 33 - \frac{40}{2} = 33 - 20 = 13[/tex]
The actual percentage of smokers in 2010 was of 23%, while the estimated was of 13%, thus, the model underestimated the percentage by 10%.

A bowl holds the 15 pieces of fruit shown below.
If Jasmine correctly writes the fraction of fruit that are apples, which of the following would be the numerator of the fraction?
Answer:
Step-by-step explanation:
8/15
The fraction representing the number of apples is 8/15 thus, the numerator will be 8.
What is numerator and denominator?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, if we divide two numbers by each other then the upper word is called the numerator, and the lower word is called the denominator.
As per the given apple lot,
The total number of fruits = 20
The total number of apples = 8
Thus, the fraction will be 8/20 where the numerator will be 8.
Hence "The fraction representing the number of apples is 8/15 thus, the numerator will be 8".

The probability of rolling something less than 5 is 1/3.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, A 12-sided die can be made from a geometric solid called a dodecahedron.
The sample space is, {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
So, The probability of getting any number is 1/12.
Therefore, The probability of getting a number less than 5 is,
P(1) + P(2) + P(3) + P(4).
= 1/12 + 1/12 + 1/12 + 1/12.
= 4/12.
= 1/3.
So, The probability of getting a number less than 5 is 1/3.

vertex of h(x)=−4x 2 +12x−7
Answer:
x = 1.5
Step-by-step explanation:
To get the vertex of a quadratic equation you can use the formula
x = -b/2a
where f(x) = ax² + bx + c
So you would get -12/2(-4)
-12/-8
x = 1.5

You want to collect data on a random sample of products created on a production line. The company has
two types of products (A and B). For each of the scenarios described below, please name the sampling
method.
A. You randomly select the serial numbers of 50 products and collect information on each item selected.
B. You randomly select 20 products of type A and 20 products of type B.
c. You select every 20th product as they come off the production line.
Using sampling classifications, it is found that:
a) Cluster sampling.b) Stratified sampling.c) Systematic sampling.-----------------------
Samples are classified as:
Convenient: Sample drawn from a conveniently available pool. Random: Basically, put all the options into a hat and drawn some of them. Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed. Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.-----------------------
Item a:
Products chosen, and then each is used. Thus, cluster sampling.-----------------------
Item b:
A number of elements from each group, not all, thus, stratified sampling.-----------------------
Item c:
Every kth element, in this case, every 20th, thus systematic sampling.A similar question is given at https://brainly.com/question/24188753

Evaluate the following problems. Show your work
Step-by-step explanation:
7.)
13 - 24 / (8 - 2) × 1³
brackets first
13 - 24 / (6) × 1³
exponents next
13 - 24 / 6 × 1
dot operations (division, multiplications) next
13 - 24 / 6 × 1 = 13 - 24×1/6 = 13 - 24/6 = 13 - 4
dash operations (adding, subtracting) last
13 - 4 = 9
8.)
-81/9×4 + 8²
no brackets, so exponents first
-81/9×4 + 64
dot operations next (often best is going left to right, but the sequence actually does not matter; e.g. -81/9×4 = -81×4/9).
-81/9×4 + 64 = -9×4 + 64 = -36 + 64
dash operations last (again, sequence does not matter, if you handle all signs correctly, but in case of doubt just go left to right).
-36 + 64 = 28

ii. Write an expression to determine the length of the room in units of 3 feet (yards).
Preview
iii. Write an expression to determine how many times as long the room is than 3 feet.
Preview
The dimension of a room is the length and width of the room.
The length of the room in yard is L/3An expression for the length of the room in unit of 3ft is 3LThe room is longer than 3 feet, in L timesFrom the question, we have:
[tex]L \to[/tex] Number of feet
(a) An expression for the length of the room in yards
In standard unit of conversion
[tex]1ft = \frac{1}{3} yd[/tex]
Multiply both sides by L:
[tex]L \times 1ft = L \times \frac{1}{3} yd[/tex]
[tex]L\ ft = \frac{L}{3} yd[/tex]
Hence, the length of the room in yard is L/3
(b) An expression for the length of the room in unit of 3ft
In (a), we have:
[tex]L \to[/tex] Number of feet
To calculate the length in units of 3 feet, we simply multiply L by 3
[tex]Unit = 3 \times L[/tex]
[tex]Unit = 3L[/tex]
An expression for the length of the room in unit of 3ft is 3L
(c) How many times longer the room is, than 3ft.
In (b), we have:
[tex]Unit = 3L[/tex]
The number of times (n) the room is longer than 3 ft is:
[tex]n = Unit \div 3[/tex]
[tex]n = 3L \div 3[/tex]
[tex]n = L[/tex]
The room is longer than 3 feet, in L times

No the larger the number the steeper the slope. 1 would be a steeper slope than a number less than 1.
sin(60-theta)sin(60+theta)
Step-by-step explanation:
[tex] \sin(60 - \theta) \sin(60 + \theta) \\ = \{ \sin(60) \cos( \theta) - \sin( \theta) \cos(60) \} \{ \sin(60) \cos( \theta) + \cos(60) \sin( \theta) \} \\ = \{ \frac{ \sqrt{3} }{2} \cos( \theta) - \frac{1}{2} \sin( \theta) \} \{ \frac{ \sqrt{3} }{2} \cos( \theta) + \frac{1}{2} \sin( \theta) \} \\ \\ [/tex]
from difference of two squares:
[tex]{ \boxed{(a - b)(a + b) = ( {a}^{2} - {b}^{2} ) }}[/tex]
therefore:
[tex] = \{ {( \frac{ \sqrt{3} }{2}) }^{2} { \cos }^{2} \theta \} - \{ {( \frac{ \sqrt{3} }{2} )}^{2} { \sin }^{2} \theta \} \\ \\ = \frac{3}{4} { \cos }^{2} \theta - \frac{3}{4} { \sin}^{2} \theta[/tex]
factorise out ¾ :
[tex] = \frac{3}{4} ( { \cos }^{2} \theta - { \sin}^{2} \theta) \\ \\ = { \boxed{ \frac{3}{4} \cos(2 \theta) }}[/tex]
