A line plot with the lengths of meteors is shown. Two more identical meteor measurements were added so that the total length of all meteors measured is 16 inches. What is the length of each new meteor?
Answer:
The answer is 1 3/8 (D)
Step-by-step explanation:
If you added the amounts of each tick mark (which would be 13 2/8), and then subtracted it by 16, it would be 2 6/8. 2 6/8 divided by two (because we need to find the length of both of the indentical meteors) would be 1 3/8.
Now, to make sure it is 1 3/8: 13 2/8 + 1 3/8 + 1 3/8 = 16.
It is confirmed, 1 3/8 (Answer D) is the correct answer.
(Also, I took this test and got it correct :D)

A square has a side length of 2x+5, write an expression to find the perimeter of the square
Answer:
4(2x+5) or 8x+20
Step-by-step explanation:
Answer:
8x + 20
Step-by-step explanation:
Side = 2x + 5
Perimeter of square = 4*side
= 4*(2x + 5) {Use distributive rule:a(b +c) = a*b +a*c}
= 4*2x + 4*5
= 8x + 20

A Christmas party DJ only
played 16 Michael Bublé
songs and 4 Mariah Carey
songs. What percentage of
the songs were sung by
Mariah Carey?
Answer:
20% were MC
Step-by-step explanation:
Divide number of Mariah Carey songs by total songs.
Total songs = 16 + 4 = 20
4/20 = 0.2
Multiply by 100 to get percent:
0.2 x 100 = 20%
The answer is 20%

In recent years, Japan's population has been declining at a rate of 0.1% per year. If you were to write an exponential equation representing the situation, what would the decay factor be?
A- .999
B- 0.99
C- .91
D- 1.001
the decay factor for the given decay rate is 0.999
Given :
In recent years, Japan's population has been declining at a rate of 0.1% per year.
we need to find the decay factor for the given exponential rate.
The rate of decay is 0.1%. To remove percentage we divide by 100
so , [tex]\frac{0.1}{100}=0.001[/tex]
The decay rate is 0.001
To find out decay factor , we subtract decay rate from 1
decay factor is 1- decay rate
Decay factor is 1-0.001=0.999
So the decay factor for the given decay rate is 0.999

the area of a rectangle is 144cm squared.if the length is 16cm. What's the perimeter?
Answer:
50
Step-by-step explanation:
lxb=144
16xb=144
b=9
perimeter=2(l+b)
=2(16+9)
=50 cm
Answer: 50cm squared
Step-by-step explanation:
First we need to find the side lengths,
In order to find the area you do,
A = Length x height
we know that the area is 144 and the length is 16.
144=16 x height
144 = 16 x ?
So know we need to find the height, so we do 144/16= 9
so the height 9 cm.
The question is not asking for the height, but the peremeter.
Peremeter = (Length x 2) + (height x 2)
peremeter= 16 x 2 + 9 x 2
peremeter = 32+18
peremeter = 50 cm squared
so the peremeter is 50 cm squared.

the volume of a cylinder is 8,478 cubic inches, and the radius is 15 inches. Which measurement is closest to the height of this cylinder in inches?
Answer:
The height of the cylinder 'h' = 12 inches
Step-by-step explanation:
Explanation:-
Given Volume of the cylinder = 8,478 cubic inches
Radius of the cylinder = 15 inches
Volume of the cylinder is determined by
[tex]V = \pi r^{2} h[/tex]
8,478 = 3.14 × (15)² h
[tex]h = \frac{8478}{3.14 X 225} = 12 inches[/tex]
The height of the cylinder 'h' = 12 inches

As one of the groundskeepers at Gardens, Tim planted 86 myrtle trees along both sides of the entrance driveway. Of the trees he planted, about 34% had white flowers and the rest had pink flowers. How many of the trees that Tim planted had white flowers?
A. 29
B. 40
C. 52
D. 57
Answer:
Option A : 29 is the correct answer.
Step-by-step explanation:
Given that:
Number of trees planted by Tim = 86
Percent of trees with white flowers = 34%
Number of trees = 34% of 86
Number of trees = [tex]\frac{34}{100}*86[/tex]
Number of trees = 0.34 * 86
Number of trees = 29.24
Rounding to nearest whole number
Number of trees = 29
Hence,
Option A : 29 is the correct answer.

irrational numbers are closed under subtraction true/false
Answer:
False
Step-by-step explanation:
a+(-a)=a-a = 0 which means irrational numbers are not closed under addition or subtraction.
False. Irrational numbers are not closed under subtraction.
Given data:
Closure under subtraction means that if you subtract two irrational numbers, the result will always be another irrational number.
However, this is not true for irrational numbers.
For example, consider the irrational numbers √2 and √2 + √2. Both of these numbers are irrational. However, when we subtract √2 from √2 + √2, we get:
(√2 + √2) - √2 = √2
The result, √2, is still an irrational number. But if we subtract two irrational numbers like √2 from √2, we get:
√2 - √2 = 0
The result, 0, is a rational number, not an irrational number.

Answer:
21.5≤μ≤25.2
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar±(z*s/√n)
xbar is the mean = 23.7
s is the standard deviation= 16.3
n is the sample size = 438
z is the z score at 95% confidence level
z = 1.96
Substitute into the formula
CI = 23.7±(1.96×16.3/√438)
CI = 23.7±(1.96×16.3/20.93)
CI = 23.7±(1.96×0.77788)
CI = 23.7±1.5264
CI = (23.7-1.5264, 23.7+1.5264)
CI = (21.4736, 25.2264)
The confidence interval to the nearest tenth is 21.5≤μ≤25.2
