The following set of data represents the age in years of newly married ladies in Desai. 15,25,17,20,22,24,19,16./ This data was collected after Deborah made an allegation that ladies in Desai get married at an age other than 18 years as is required by law. Does this data provide enough evidence at 5% level of significance to believe that the mean ages of ladies getting married in Desai is actually different from 18 years as claimed by Deborah?
Answer:
There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.
Step-by-step explanation:
Given the data:
15,25,17,20,22,24,19,16
Using calculator :
Mean value, xbar = 19.75
Standard deviation, s = 3.69
Samoke size, n
H0 : μ = 18
H1 : μ > 18
The test statistic :
Tstatistic = (xbar - μ) ÷ (s / sqrt(n))
Test statistic = (19.75 - 18) ÷ 3.69/ sqrt(8))
Test statistic = 1.75 ÷ 1.3046
Test statistic = 1.34
The Pvalue from test statistic ; df = n - 1 = 8 - 1 = 7
Pvalue = 0.111054
Decision :
If Pvalue < α ; reject H0
0.111053 > 0.05 ` Hence, we fail to reject H0
We can conclude that, There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.
Which of the functiors below could have created this graph
Answer:
bces
Step-by-step explanation:
Please help :) Giving brainliest.
Answer:
D
Step-by-step explanation:
Which of the coordinate points below will fall on the line with the consent of the personality is 1/4 select all that apply
Answer:
A, C, and D
Step-by-step explanation:
Constant of proportionality, k = y/x
Thus, all points on a line will have the same value of k.
Here, the value of k is given as ¼.
The coordinate points that will fall on a line where k = ¼, will give us the value of ¼ when we divide its y-coordinate by its x-coordinate.
Thus:
(4, 1) will give us k = y/x = ¼
(12, 3) will give us k = y/x = 3/12 = ¼
(20, 5) will give us k = y/x = 5/20 = ¼
Therefore, the options that apply are: A, C, and D

What is 1/6 as a decimal?
Give your answer rounded to 3 decimal places.
Answer:0.16666
Step-by-step explanation:
As we know that
Therefore, 1/6 or 0.16666... can be written rounding off to three decimal digits such as: 0.1666... 0.167 (rounding off to three decimal digits)
Write an expression representing the perimeter of the rectangle as the sum of the four side lengths.
Answer:
2x+ 2(x+4/5)
Step-by-step explanation:
Perimeter = 2l + 2w

w = x+4/5
16. Garrett can complete four laps around the
track in 7 minutes and 45 seconds. How
many full laps can he complete in 1 hour
Answer:
Step-by-step explanation:
45 seconds = 45/60 = 0.75 minutes
7 minutes 45 seconds = 7.75 minutes
One hour = 60 minutes
Number of full laps = 60/ 7.75 = 6000/775 = 7.74
He can make 7 full laps in one hour

Answer:
sin(θ) ≈ -0.92
cos(θ) ≈ 0.38
tan(θ) = -2.40
Step-by-step explanation:
Let r represent the distance of the point from the origin. The Pythagorean theorem tells us ...
r² = (5)² + (-12)²
r² = 169
r = √169 = 13
The trig relations for a point on the terminal ray are ...
(x, y) = (r·cos(θ), r·sin(θ))
Then ...
sin(θ) = y/r = -12/13 ≈ -0.92
cos(θ) = x/r = 5/13 ≈ 0.38
tan(θ) = y/x = -12/5 = -2.40
The locations, given in polar coordinates, for two ships are (8 mi, 63°) and (8 mi, 123°). Find the distance between the two ships.
Answer:
It can therefore be noted that all angles are equal and thus the resulting triangle is actual an equilateral triangle and thus all the sides are equal. It can be concluded that the ships are 8 miles apart.

Part A. Name the polygon.
cm
Part B. Enter the perimeter, in centimeters, of the
figure.
cm
Answer:
(a) Pentagon
(b) Perimeter= 1435cm
Step-by-step explanation:
Given
[tex]Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m[/tex]
Though the question has a missing attachment, it can still be answered
Solving (a): The name of the polygon
Since we are given 5 side lengths, we can say that the polygon has 5 sides.
Such polygon is referred to as, a pentagon
Solving (b): The perimeter (in cm)
To do this, we simply add up the side lengths
[tex]Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m[/tex]
[tex]Perimeter= 3.65m+ 2.24m+ 2.57m+ 2.24m+ 3.65m[/tex]
[tex]Perimeter= 14.35m[/tex]
Convert to cm
[tex]Perimeter= 14.35*100cm[/tex]
[tex]Perimeter= 1435cm[/tex]
Solve for variable.
3k = 36
Answer:
k = 12
Step-by-step explanation:
Given 3k = 36 we want to isolate the variable (k) using inverse operations
So we want to get rid of the 3
3k = 3 times k (multiplication)
The inverse of multiplication is division so to get rid of the * 3 we want to divide by 3. Remember whatever we do to one side we have to do to the other side so we are going to divide each side by 3
3k/3=k
36/3=12
we're left with k = 12

The Great Park Balloon in Orange County, California, is a big orange sphere with a radius of 36 feet. Find its surface area (in square feet). (Use 3.14 for . Round your answer to one decimal place.)
Answer:
16286
Step-by-step explanation:
the formula for surface area for a sphere is 4 pi r^2
So substitute for r and you get 4pi*1296 then do 3.14 * 4 * 1296 and you get 16286.02 then round it to one decimal (it cancels out) and you get 16286.
