Answer:

Step-by-step explanation:
By adding 4 to the numerator 2, we get 6 / 5.
Since 1 / 2 = 0.5, we need to find a number that we can divide 6 by to get 0.5.
Since 0.5 is half of a unit, we just need to find a number which it's half is 6.
6 * 2 = 12 (meaning 6 is half of 12), so 6 / 12 = 0.5 meaning 6 / 12 it's equivalent to 1 / 2.
12 - 5 = 7, so we need to add seven to the denominator to make the fractions equivalent.

A 12-sided die can be made from a geometric solid called a dodecahedron. Find P(“roll something less than 5”)
Answer:
For probability ,Here possible outcome are 4

mark me as brainliest ❤️
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.

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".

Answer:
Use the given functions to set up and simplify f(−4).

Step-by-step explanation:
Plug x + h into the function f and simplify to find f(x + h). Now that you have f(x + h), find f(x + h) - f(x) by plugging in f(x + h) and f(x) and simplifying. Plug your result from step 2 in for the numerator in the difference quotient and simplify.

20 % of his paycheck to Taxes and SSI. How much is does he keep
from his check?
Answer:
$408
Step-by-step explanation:
$17 x 30 = $510
100% = 510
20% = taxes
remaining amount = 80%
80% of 510 = 0.80 * 510
0.80 * 510 = $408

c. When measuring the dimensions of a room a carpenter uses a tape measure that only displays a number of feet, L, on the metal tape.
(The carpenter's tape measure does not display inches).
i. Write an expression to determine the length of the room in yards.
Preview
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

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 :

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

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%.
