Marco is helping his dad plant 600 new trees in the woods behind their house. They plant 10% on Monday and 20% on Tuesday. Marco says that must mean they planted 30 trees so far. Do you agree with Marco's statement? Why or why not?
Answers
Answer:
No because they planted 180 trees
Step-by-step explanation:
add 20% + 10% to get 30%
30% of 600 is 180
Answer:
I Disagree
Step-by-step explanation:
to find the answer I did 20 divided by 100 and got 0.2 the multiplied 0.2 times 600 and the answer was 120 and that alone can tell you they planted way more 30 trees. Let me know if I'm wrong

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

A survey showed that 79% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 16 adults are randomly selected,
find the probability that no more than 1 of them need correction for their eyesight. Is 1 a significantly low number of adults requiring eyesight
correction?
The probability that no more than 1 of the 16 adults require eyesight correction is
(Round to three decimal places as needed.)
Answers
Answer:
P (X≤1) = 0.000
Step-by-step explanation:
Data given:
p = 79% = 0.79
q = 1 - 0.79 = 0.21
n = 16
P (no more than 1 in 16 adults) = P (X≤1)
P (X≤1) = P (X=0) + P (X=1)
We can find the probability by using binomial functions:
\(P=\frac{n!}{x!(n-x)!}p^x(1-p)^{n-x}\)
P(X=0):P(X=0) = (16! / 0!(16-0)!) · 0.79⁰ · 0.21¹⁶
Use calculator to solve:
P(X=0) = 0.000000000798
P(X=1):P(X=1) = (16! / 1!(16-1)!) · 0.79¹ · 0.21¹⁵
Use calculator to solve:
P(X=1) = 0.000000034506
P(X≤1)P (X≤1) = P (X=0) + P (X=1)
P (X≤1) = 0.000000000798 + 0.000000034506
P (X≤1) = 0.00000003530
P (X≤1) = 0.000
As 1 is a very low number, its probability is very small

A company charges $3.00 for every 2 pounds of oranges sold plus a $3.00 shipping fee. Based on this information, which graph best shows this relationship between the cost of oranges, y, and the number of pounds, x?
Answers
The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.
Given that, a company charges $3.00 for every 2 pounds of oranges sold plus a $3.00 shipping fee.
What is graph?In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".
Let the total cost of oranges be y and the number of pounds of oranges be x.
So, the equation to represent the given situation is y=2x+3
By substituting x = 1, 2, 3, 4, 5,....we get
y = 2(1)+3=5
y = 2(2)+3 = 7
y = 2(3)+3 = 9
y = 2(4)+3 = 11
So, the coordinates to plot the graph are (1, 5), (2, 7), (3, 9) and (4, 11) and so on.
The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

65 ≥ 38.50 + 4x where x is the number of boxes of mints.
65 - 38.50 ≥ 4x

32 (B)
Step-by-step explanation:
Because there is a total of 96 apples and oranges, you would divide 96 by 12 because 4 + 8 = 12. 96/12 is 8, so we know that each part (1 part of the ratio) would be 8. Since we are finding the number of oranges, you would multiply 4 x 8 which is 32. (B)

The ratio of students to teachers at a school is 19:1. At this school, there are 400 people (teachers and students). How many of these 400 people are students?
(enter the number only, without the unit)
Answers
Answer:
380
Step-by-step explanation:
First, figure out that in the ratio of 19 : 1, there are 20 people. 400 divided by 20 = 20. This means you have to multiply the number of students in the original ratio (19) by 20 to get the actual amount of students.
19 × 20 = 380 so there are 380 students.

What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of a parallelogram is the product of the base and the height of the figure.
The area of a parallelogram = Base x Height
The area of the rectangle = length × Width
We are given that;
Measure of square tiles= 8x8
Length = 2 2/3 ft
Now,
There are different ways to approach this problem, but one possible method is:
Find the area of one tile in square feet:
Convert 2 2/3 ft to a mixed number of inches: 2 × 12 + 2 + 2/3 = 26 2/3 in
Convert 26 2/3 in to feet: 26 2/3 ÷ 12 = 2 2/3 ft
The area of one tile is the product of its length and width: (2 2/3 ft) × (2 2/3 ft) = 8/3 ft × 8/3 ft = 64/9 ft²
Find the total number of tiles in the mosaic:
The mosaic has an 8 × 8 array of tiles, so there are 8 × 8 = 64 tiles in total
Find the area of the whole mosaic in square feet:
Multiply the area of one tile by the number of tiles: (64/9 ft²) × 64 = 4096/9 ft² ≈ 455.11 ft²
Therefore, the area will be approximately 455 square feet.
