Answer:
D. g(x) = (1/4 x)^2
Step-by-step explanation:
We have to choose a solution in which the point (4, 1) works.
A) g(x) = 1/4(x^2) = 1/4(4^2) = 1/4(16) = 4 ≠ 1
B) g(x) = (1/2 x)^2 = (1/2 * 4)^2 = 2^2 = 4 ≠ 1
C) g(x) = 4(x^2) = 4(4^2) = 4(16) = 64 ≠ 1
D) g(x) = (1/4 x)^2 = (1/4 * 4)^2 = 1^2 = 1

g Suppose that you randomly selected 20 adults. If 18% of the population smoke, a) Using the Range Rule of Thumb, what is the minimum number of usual smokers we can expect to get out of 20 adults
Answers
Answer:
0.16
Step-by-step explanation:
The computation of the minimum no of usual smokers expected to get out of 20 adults is shown below:
Here the standard deviation is
[tex]= \sqrt{npq} \\\\= \sqrt{20\times 0.18 \times (1 - 0.18)}\\\\= \sqrt{20\times 0.18\times 0.82}\\\\= \sqrt{2.952}[/tex]
= 1.72
Now the minimum no of smokers is
[tex]= np - 2\times 1.72\\= 20 \times 0.18 - 3.44\\\\= 0.16[/tex]

when solving 20x+5y=40 for y
Answers
20x + -5y = 40
Solving
20x + -5y = 40
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation.
20x + -5y + 5y = 40 + 5y
Combine like terms: -5y + 5y = 0
20x + 0 = 40 + 5y
20x = 40 + 5y
Divide each side by '20'.
x = 2 + 0.25y
Simplifying
x = 2 + 0.25y
The answer is y=-4x+8. The paper shows how to solve the equation step by step.

In the figure below, tan B = 4/3. If BC = 15 and DA = 3, what is the length of DE ?
A. 8
B. 12
C. 6
D. 9
Answers
Answer:12
Step-by-step explanation:
The length of the segment in the right triangle is 6 unit.
What is an angle ?An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
Given that,
A right angle triangle,
In which, tan B = 4/3, BC = 15 and DA = 3,
the length of DE = ?
suppose, the length of BD is x
and the length of DE is h.
we can use trigonometric formula her;
sin B = AC/BC
sin B = AC/15
if the value of tan B is 4/3 then the value of sin B will be 4/5.
AC/15 = 4/5
AC = 12
Now, tan B = 4/3 = 12/AB
AB = 16
Now we can use similarity of triangles;
DE/BD = AC/AB
DE = BD x (AC/AB)
BD = AB/2
DE = 8 x 12/16
= 6
Therefore, the length of DE is 6 unit.

Marcus collects donations and sends care packages to troops overseas. He has 36 bars of soap and 24 toothbrushes and wants to arrange the items so the packages are identical. What is the greatest number of packages that Marcus can make using all the soap and toothbrushes? ) What is the greatest number of packages of soap and toothbrushes that Marcus can make? Marcus can make at most 12 packages. ) How many bars of soap and toothbrushes are in each package? 2 toothbrushes in each pockage 6) There are ? bars of soap and ? toothbrushes in each package?
Answers
Answer:
Marcus can make 12 packages, with 2 toothbrushes and 3 bars of soap in each package.
Step-by-step explanation:
For all the packages to be identical, they must all contain the same numbers of soaps and the same nuber of toothbrushes.
The ratior of soaps to brushes is 36/24 = 3/2
He could make 24 packages, each with 1 tootbrush and (3/2) bars of soap.
Assuming he is not going to cut soap bars in half, that is no good.
To make the numbers of individual items come out as integers, the smallest number he can multiply them by is the denominator on the (3/2) bar of soap. That would be a 2.
So he can makes packages with toothbrushes = 2 x 1 =2
and soap bars = 3/2 x 2 = 3
He can put 5 items in each package - 3 soap bars and 2 toothbrushes.
That means he makes 12 packages.
The greatest number of packages is 12 with 2 toothbrushes and 3 soap bars in each package.
It is given that the Marcus has 36 bars and 24 toothbrushes and wants to arrange the items so the packages are identical.
It is required to find the greatest number of packages that Marcus can make using all the soap and toothbrushes.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called denominator.
Marcus has number of bars of soap = 36 and
Number of tooothbrush = 24
The ratio of soap bars to toothbrushes = 36:24 or
= 3:2
It meanse Marcus can make 24 packets with [tex]\frac{3}{2}[/tex] soap bars and toothbrush
Because there are 24 toothbrushes but the number of bars can not be in fraction so multiply by 2 on denominator, we get:
Number of toothbrushes = 2×1 = 2
Number of soap bars = [tex]\frac{3}{2}[/tex] ×2 = 3
Now he can make total 12 packets with 2 toothbrushes and 3 soap bars.
Sum of toothbrushes and soap bars = 24+36 = 40
Number of soap bars and toothbrush in each packet = 2+3 = 5
Number of packages= [tex]\frac{60}{5}[/tex] = 12
Thus, the greatest number of packages is 12 with 2 toothbrushes and 3 soap bars.
