Answer: Systematic Random Sample
Step-by-step explanation:
Based on the information given, the method that would produce a random sample of 10 plants is the systematic random sample.
Systematic sampling is referred to as a probability sampling method whereby a random sample, that has a fixed periodic interval, will be chosen from the larger population. It should be noted that the fixed periodic interval, can be gotten by dividing the population by desired sample size.
In this case, since there are 5000 plants and there needs to ba a random sample of 10 plants, the fixed periodic interval will be: = 5000/10 = 500th plant. That means the 500th plant will be chosen.

PLEASE NO LINKS OR "Sorry i don't know this" or anything related to that.
Answer:B) 150
Step-by-step explanation:
Area of rec= L×W
= 10×30= 300
Area of shaded area= 1/2 Base× Height
1/2×10×15=75
75×2 = 150
Area of unshaded part= 300-150= 150
Answer:
150 Square Units
Step-by-step explanation:
(Sorry if I become confusing)
The base of the triangles is 10 units.
The height of the triangles is 15 units.
The formula I used was A=[tex]\frac{1}{2}bh[/tex]
b=base and h=height A=area
A=[tex]\frac{1}{2}(10)(15)[/tex]
A=[tex]\frac{1}{2}(10)(15)[/tex]=75
A=75
Multiply by two to get the area for both triangles.
75·2=150

Answer:
The answer is 8.5
Step-by-step explanation:
Just list all the numbers and cross them out one by one.
Add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median.
In ΔUVW, the measure of ∠W=90°, VW = 32 feet, and WU = 78 feet. Find the measure of ∠V to the nearest degree.
Answer: [tex]67.68^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle W=90^{\circ}[/tex]
[tex]VW=32\ ft[/tex]
[tex]WU=78\ ft[/tex]
from the figure, we can write
[tex]\Rightarrow \tan v=\dfrac{UW}{VW}\\\\\Rightarrow \tan v=\dfrac{78}{32}\\\\\Rightarrow \tan v=2.437\\\Rightarrow v=\tan^-1(2.437)\\\Rightarrow v=67.68^{\circ}[/tex]

The functions ) and g(x) are shown on the graph.
Rx) = x2
What is g(x)?
g(x) (2, 12)
Given:
The graphs of f(x) and g(x).
The function f(x) is given by:
[tex]f(x)=x^2[/tex]
The graph of g(x) passes through the point (2,12).
To find:
The function g(x).
Solution:
From the given graph it is clear that the vertex of both function f(x) and g(x) is at (0,0). It means the graph of f(x) is not translated. It means the graph of f(x) is only vertically stretched to get the graph of g(x). So,
[tex]g(x)=kf(x)[/tex]
Where, k is the stretch factor.
[tex]g(x)=kx^2[/tex] ...(i)
The graph of g(x) passes through the point (2,12). Putting [tex]x=2, g(x)=12[/tex], we get
[tex]12=k(2)^2[/tex]
[tex]12=k(4)[/tex]
[tex]\dfrac{12}{4}=k[/tex]
[tex]3=k[/tex]
Putting [tex]k=3[/tex] in (i), we get
[tex]g(x)=3x^2[/tex]
Therefore, the correct option is A.

95 - 3/4 what is the value of the expression
Answer:377 /4 = 94 and 1 / 4 =94.25
Step-by-step explanation:
Subtract
95 − 3 /4
= 377 / 4
Convert integer to fraction
95 = 95 / 1
Find common denominator
95 over 1
− 3 over 4
= ( 95 × 4 ) over ( 1 × 4 )
− ( 3 × 1 ) over ( 4 × 1 )
= 380 over 4
− 3 over 4
4 is the least common multiple of denominators 1 and 4. Use it to convert to equivalent fractions with this common denominator.
Subtract
380 over 4
− 3 / 4
= ( 380 − 3 ) / 4
= 377 /4
Simplify
377 / 4
= 94 and 1 /494
Reduce fraction to lowest terms
1 is the greatest common divisor of 377 and 4. The result can't be further reduced.
Step 2 of 2: Simplify, sub-step b: Convert improper fraction to mixed number.
Convert improper fraction to mixed number
377 /4
= 94 1 /4
377 ÷ 4 = 94 remainder 1
By writing the whole number as a fraction, we will see that the solution is 377/4
How to solve the expression?
Here we want to take the difference between a whole number and a fraction:
95 - 3/4
To do this, we need to write the whole number as a fraction, to do it, we multiply and divide it by 4:
95 = (4/4)*95 = 380/4
Now we rewrite our expression as:
95 - 3/4 = 380/4 - 3/4 = 377/4
This is the solution of the expression.

The probability that the student will pick a ball that is either red, orange, or green is 0.75
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability that the student will pick a ball that is either red, orange, or green be P
Now , the total number of balls in the container = 1000 balls
And , probability that the student will pick a ball that is either red, orange, or green can be calculated as the sum of the probabilities of picking a red ball, an orange ball, or a green ball. That is,
P(Red or Orange or Green) = P(Red) + P(Orange) + P(Green)
The probability of picking a red ball is 400/1000 = 0.4
The probability of picking an orange ball is 250/1000 = 0.25
And the probability of picking a green ball is 100/1000 = 0.1.
Therefore , P (Red or Orange or Green) = 0.4 + 0.25 + 0.1 = 0.75
Hence , the probability is 0.75

A dilation by scale factor then a translation of

Answer:
A reflection in the line y = -2, then a translation 2 units right.
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Rigid transformation are transformation that preserves the shape and size of the object. Rotation, reflection, translation are rigid transformation whereas dilation is not a rigid transformation.
Any transformation regarding dilation changes the side length of the object and hence the area.
From the question, only one option is right. The rest options are not right because they involve dilation. The correct option is:
A reflection in the line y = -2, then a translation 2 units right.
