The population standard deviation of these data is approximately
(1) 3. 5
(3) 79. 7
(2) 13
(4) 80
If the value of the mean is 79.6923 then the standard deviation is 3.5. Then the correct option is A.
What is a standard deviation?It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.
The following table shows the heights, in inches, of the players on the opening-night roster of the 2015-2016 New York Knicks.
84, 80, 87, 75, 77, 79, 80, 74, 76, 80, 80, 82, 82
The mean will be
N = 13
[tex]\mu = \dfrac{84+ 80+ 87+ 75+ 77+ 79+ 80+ 74+ 76+ 80+ 80+ 82+ 82}{13}\\\\\mu = \dfrac{1036}{13}\\\\\mu = 79.6923[/tex]
Then the standard deviation will be
[tex]\sigma = \sqrt{\dfrac{\Sigma _{i=2}^N (x_i - \mu)^2}{N}}\\\\\sigma = \sqrt{\dfrac{(84-79.6923)^2+(80-79.6923)^2+ ..... + (82-79.6923)^2}{13}}\\\\\sigma = 3.4947128281848 \approx 3.5[/tex]

In short, this means that Nicole can buy anything that costs $12.50 or less.
A botanist is using two types of plants for an experiment. she writes inequalities to model the constraints on the number of each type of plant she can use. she uses linear programming to find the vertex of the feasible region that results in the minimum value, in dollars, of the cost function. if that vertex is (5, 39), what do the coordinates represent? buying five of one type of plant and 39 of the other type of plant results in the lowest cost. buying five of each type of plant costs $39, which is the lowest possible cost. the lowest possible cost of the plants is $5, which occurs when 39 of each type of plant are bought. the lowest possible cost of the plants is $5, which occurs when a total of 39 plants are bought.
The coordinates represent the numbers of plants of each type she can use and minimize the cost
Let x be the number of plants of one type.
y be the number of plants of the other type.
What is the meaning of the vertex of the feasible region?
The optimal solutions will occur at one or more of the extreme points this is the vertices of the feasible region.
We have, The vertex of the feasible region that results in the minimum value of the cost function is (5,39).
That means buying 5 of one type of plant and 39 of the other type of plant results in the lowest cost.

Answer:
Yes
Step-by-step explanation
Lines are perpendicular when they have the reprocial slope with the opposite sign.
Yes, the lines having slopes 6 and -1/6 are perpendicular.
What is slope?The slope of a line is a number that describes the direction of the line. The formula of calculating slope is calculated as under:

What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
Two similar solids have a surface area of 48ft^2 and 147ft^2 respectively.
If the volume of the smaller solids is 320ft^3.
Since the solids are similar, the ratio of the surface areas is equal to the square of the scale factor, k.
Thus, k2 = 147 / 48 , or k = 49/16 = 7/4
The ratio of the volumes of the solids is equal to k3, which gives:
V / 320 = (7/4)^3
where V is the volume of the larger solid.
V = 320 x (7/4)^3
= 1715 cubics in

A country pledges to reduce its annual CO2
emissions by 5% per year. If the emissions in
2022 are 6,080 Mt (metric megatons), what are
the maximum allowable emissions in the year
2029?
A country pledges to reduce its annual CO₂ emissions by 5% per year, the maximum allowable emissions in the year 2029 is, 4245.89 Mt
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
A country pledges to reduce its annual CO₂ emissions by 5% per year
The emissions in 2022 are 6,080 Mt
The maximum allowable emissions in the year 2029 = ?
In 2022 CO₂ emission = 6,080 Mt
5% reduces next year
So, In 2023
CO₂ emission = 6080(1 - 0.05)
In 2024
CO₂ emission = 6080(1 - 0.05)(1 - 0.05)
So after 7 years in 2029
CO₂ emission = 6080(1 - 0.05)⁷
= 4245.89
Hence, the maximum permissible emission is 4245.89 Mt

Elimination was used to solve a system of equations.
One of the intermediate steps led to the equation 2x = 8.
Which of the following systems could have led to this equation?
3x - y = 15
x + y = 7
x + 3y = 24
- x - 3y = 16
4x + 2y = 14
x + y = 3
2x+2y = 8
- 2x - 2y=8
Answer:
(c) 4x + 2y = 14; x + y = 3
Step-by-step explanation:
The given equation will be the result of eliminating the y-variable from the system. When we do that for the different answer choices, we get ...
aAdd the two equations: (3x -y) +(x +y) = (15) +(7) ⇒ 4x = 22
bAdd the two equations: (x +3y) +(-x -3y) = (24) +(16) ⇒ 0 = 40
cSubtract twice the second from the first.
(4x +2y) -2(x +y) = (14) -2(3) ⇒ 2x = 8 . . . . the system we're looking for
dAdd the two equations: (2x +2y) +(-2x -2y) = (8) +(8) ⇒ 0 = 16

When the equation reduces to 0 = constant, and "constant" is not zero, it means the system of equations has no solution. (The equations describe parallel lines.)

Spongebob and Patrick are selling kelp fries to fundraise for new jellyfishing nets. They sold
small and large sizes. Spongebob sold 3 small fries and 14 large fries for a total of $203.
Patrick sold 11 small fries and 11 large fries for a total of $220. Find the cost of each size of
fries.
a
Answer:
So, cost of small size is $7 and cost of large size is $13.
Step-by-step explanation:
Let cost of each small size - x, cost of each large size - y
By the question,
3x + 14y = 203
11x + 11y = 220
From the first equation, we get,
3x + 14y = 203
or, 3x = 203 - 14y
so, x = (203 - 14y)/3
Substituting x's value in second equation :-
11x + 11y = 220
or, 11 { (203 - 14y)/3 } + 11y = 220
or, {2233 - 154y}/3 + 11y = 220
or, { 2233 -154y + 33y} = 660
or, 2233 - 121y = 660
or, 121y = 2233 - 660
or, 121y = 1573
so, y = 1573/121
so, y = 13
Now,
As we know,
x = (203 - 14y)/3
or, x = ( 203 - 14 × 13)/3
or, x = (203 - 182)/3
so, x = 21/3
so, x = 7
So, cost of small size is $7 and cost of large size is $13.
