if c and d vary inversely, and d=5/3 and c=5. write a function that models inverse variation and find d when c=10
Answers
9514 1404 393
Answer:
cd = 25/3d = 5/6Step-by-step explanation:
The inverse variation described can be either of ...
c = k/d
or
d = k/c
Either way, the equation can also be written as ...
cd = k
For the given values of c and d, the value of k is ...
(5)(5/3) = k = 25/3
So, the model can be written as ...
cd = 25/3
or
d = (25/3)/c
__
For c=10, the value of d is ...
d = (25/3)/10 = 25/30
d = 5/6

find the area of the shaded segment of the circle
Answers
9514 1404 393
Answer:
(3/2π -(9/4)√3) m² ≈ 0.8 m²
Step-by-step explanation:
The area of the segment is the difference between the area of the sector and the area of the triangle.
sector area = 1/2r²α . . . . where r is the radius and α is the central angle in radians
triangle area = 1/2r²·sin(α) . . . . same variable definitions
Then the area of the segment is ...
segment area = sector area - triangle area
segment area = (1/2)r²(α -sin(α))
The central angle subtended by the segment is 360° -300° = 60° = π/3 radians
Then the segment area is ...
A = (1/2)(3 m)²(π/3 -√3/2) = (3/2π -(9/4)√3) m² ≈ 0.8 m²

Step-by-step explanation:
Given that,
[tex]a=3+2\sqrt{2}[/tex]
We need to find the value of [tex]a\times \dfrac{1}{a}[/tex].
So,
[tex]=3+2\sqrt{2} \times \dfrac{1}{3+2\sqrt{2}}\\\\=\dfrac{3+2\sqrt{2}}{3+2\sqrt{2}}[/tex]
As numerator and dinominator is same. It means,

64 + 196 = c²
c² = 260
[tex]\sqrt{c^2} =\sqrt{260}[/tex]

What is the second number in this sequence?
Answers
Answer:
87
Step-by-step explanation:
Step 1: X is the first number
Step 2: X + 1 is the second number
Step 3: X + 2 is the third number
Step 4: X +3 is the fourth number
Step 5: Take the sum of all of those:
4x+6=354
4x=348
x=87
The second number in the sequence is 88.
87,88,89,90 = 354
Answer: Second integer is 87
Step-by-step explanation:
Sum of four consecu. integers = 354
Let the integers be x, x+1, x+2 , x+3.
Sum = 354
x+x+1+x+2+x+3 = 354
4x+6 = 354
4x = 354 - 6
4x = 348
x = 348/4
x = 87
Therefore, first integer = x =87
Second integer = x+1 = 88
Third integer = x+2 = 89
Fourth integer = x+3 = 90
So, second integer is 88 .

Answers
Answer:
d. 12√37 / 37
Step-by-step explanation:
standard formula for the distance between a point (x₀,y₀) and a line ax+by+c=0 is |a*x₀ + b*y₀ + c| / √a²+b²
(x₀,y₀) : (-2 , 3)
ax+by+c=0 : 6x - y +3 = 0
x₀ = -2 y₀ = 3 a = 6 b = -1 c = 3
d = | 6*(-2) + (-1)*3 + 3 | / √6²+(-1)²
d = 12 / √37 = 12√37 / 37

a. find the area
b. find the perimeter
Answers
Answer:
Area= 4y^2 + 14y + 12
Perimeter = 10y + 16
Step-by-step explanation:
Area of a reactangle = length × width
= (4y+6) × (y+2)
= 4y^2 + 6y + 8y + 12
= 4y^2 + 14y + 12
Perimeter of a rectangle = 2 × (a +b)
= 2 × ( 4y + 6 + y+ 2)
= 2 × ( 5y + 8)
= 10y + 16
At a high school with over 500 students, a counselor wants to estimate the mean number of hours per week that students at the school spend in community service activities. The counselor will survey 20 students in the Environmental Club at the school. The mean number of hours for the 20 students will be used to estimate the population mean. Which of the following conditions for inference have not been met?
1. The data are collected using a random sampling method.
2. The sample size is large enough to assume normality of the distribution of sample means.
3. The sample size is less than 10 percent of the population size.
Answers
Complete option:
The sample size is less than 10 percent of the population size. A. II onlyB. III onlyC. II and III onlyD. I, II, and III
Answer:
D.) I, II, and III
Step-by-step explanation:
The sample are not well randomly selected as the samples were only selected from a single source, the environmental club in the school.
Similarly only 20 samples were chosen, these 20 samples are not enough to assume normality as the minimum number of samples required to assume normality according to the Central limit theorem is 30 samples or more.
10% of the population size is :
Population size = 5000
0.10 * 5000 = 500 samples
Hence, sample size used is less than 10% of population size.

Answers
Answer:

December. total change in December is greater than change in January. 3 is greater than 2
August. the total change in hair growth is 4.
Step-by-step explanation:
total change in hair length = 2 - 1 + 3 - 4 + 3 = 3
My hair is longer in January .
total change in hair length in February = 2 -1 = 1
total change in hair length in August = 1 + 3 = 4
total change in hair length in September = 4 - 4 = 0
total change in hair length in December = 0 + 3 = 3
My hair is the longest in August because that is the month that has the highest change in hair length

Answers
Answer:
Probability Distributions
A listing of all the values the random variable can assume with their corresponding probabilities make a probability distribution.
A note about random variables. A random variable does not mean that the values can be anything (a random number). Random variables have a well defined set of outcomes and well defined probabilities for the occurrence of each outcome. The random refers to the fact that the outcomes happen by chance -- that is, you don't know which outcome will occur next.
