Answer:
n - k + 1
Step-by-step explanation:
This is assuming (because you did not say) that n and k are integers and n is greater than k.
Example: from 2 to 5 {2, 3, 4, 5} includes 5 - 2 + 1 = 4 numbers.
Example: from -6 to 4 includes 4 - (-6) + 1 = 11 numbers, namely {-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4}
A gas container in the shape of a cone has a height of 12 inches and a maximum diameter of 8 inches. When the container is filled to three-quarters of its height, what is the volume of the gas in the container, to the nearest tenth of a cubic inch.
Answer:
150.9 cubic inches
Step-by-step explanation:
volume of he gas = volume of a cone x 3/4
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius
h = height
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
8/2 = 4 inches
1/3 (22/7 x 4^2 x 12) = 201.142857 in^3
volume of the gas = 3/4 x 201.142857 in^3 = 150.9 in^3
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use pi=3.14 in any formulas used.
Answer:
Perimeter of the entire shape is 114.24
Step-by-step explanation:
Use pi x diameter of the semicircle divided by 2 + the diameter to find the perimeter of one semicircle. There are 4 semi circles so you multiply this by 4. Then you take the perimeter of the inside 8x4 = 32. Add them all together to get 114.24
Answer:
Perimeter of the entire shape is 114.24
Step-by-step explanation:
Use pi x diameter of the semicircle divided by 2 + the diameter to find the perimeter of one semicircle. There are 4 semi-circles so you multiply this by 4. Then you take the perimeter of the inside 8x4 = 32. Add them all together to get 114.24

14 yd
Area Formula= base x height
Base = 7 yd X 2yd Height= 14 yd
Volume = Area of base x height
Answer:
The volume is 196 cubic yards
Step-by-step explanation:
Given
[tex]Base\ Area = 7yd * 2yd[/tex]
[tex]Height = 14yd[/tex]
Required
The volume
The volume is given as:
[tex]Volume = Base\ Area * Height[/tex]
Where:
[tex]Base\ Area = 7yd * 2yd[/tex]
[tex]Height = 14yd[/tex]
So, the equation becomes
[tex]Volume = 7yd * 2yd * 14yd[/tex]
[tex]Volume = 196yd^3[/tex]

2) A block of cheese weighs 0.6 kg. The block is cut into smaller pieces. Each piece weighs 0.05 kg. How many pieces are there? (Show the division equation to solve for this word problem before showing multiplication to solve.)
Answer:
12
0.6/0.05
(0.6 x 100) / (0.05 x 100)
= 60/5 = 12
Step-by-step explanation:
number of pieces = total weight of the cheese / weight of each piece
0.6 / 0.05
to divide easily, convert the decimals to whole number by multiply both the denominator and numerator by 100
(0.6 x 100) / (0.05 x 100)
= 60/5 = 12

Answer.
Step-by-step explanation:
Select all the correlation coefficients that represent a linear model with a weak correlation .
A. -0.982
B. -0.618
C. -0.103
D. 0.204
E. 0.907
F. 1
Answer:
C) -0.103 and D) 0.204
Step-by-step explanation:
A linear model with a weak correlation is gonna have an r value closest to 0, whether it be negative or positive. C and D seem to be the best choice as they're closest to 0.

Kira brought chocolate and vanilla cupcakes to school for her birthday. 80 students decided to take a cupcake, and 32 of them picked vanilla. What percentage of the students picked a vanilla cupcake?
Answer:
40%
Step-by-step explanation:
Percentage of students that picked a vanilla cupcake = (students that picked a vanilla cupcake / total number of students)x 100
(32 / 80) x 100 = 40%
Angle E and angle H are supplementary. If angle E has a measure of 156 degrees, find the measure of angle H
Answer:
24 degrees
Step-by-step explanation:
Supplementary angles sum up to give 180°
E + H = 180°
156 + H = 180
H = 180 - 156
H = 24°

7. Giovanni made the design below for an art project. What is the area of the drawing? 13 in. 5 in. 4in.
Answer:
75 in^2
Step-by-step explanation:
Given data
From the figure
We can see a rectangle and a triangle
The area of the rectangle is
Area= L*W
Area= 13*5
Area= 65 in^2
Area of the triangle
Area= 1/2b*h
Area= 1/2*4*5
Area= 2*5
Area= 10 in^2
Hence the area of the composite figure is
Area= 65+10
Area= 75 in^2
find the area of each circle (use pi =3.14)
16mm
Answer:
200.96
803.84
Step-by-step explanation:
I wasn't sure if 16mm was the radius or diameter. If it's the diameter then use the first answer. If it was the radius then use the second answer.
In order to find the area of a circle use equation
[tex]A=\pi r^2[/tex]
r = radius, which is half of the line along the circle. If you have the diameter simply divide it by two and you have the radius.

HELPPP WHAT IS THE ANSWER DONT SENT A FILE PLZ EXPLAIN STEP BY STEP PLZ I DINT HAVE A LOT OF TIME
Answer:
2nd option
Step-by-step explanation:
Consider the coordinates of T(- 3, 3 ) → T' (3, - 1 )
- 3 → 3 is 6 units right in the positive x-direction
3 → - 1 is 4 units down in the negative y- direction
Then translation rule is
(x, y ) → (x + 6, y - 4 )
The mean of a data set is 124. The mean absolute deviation is 38. What is the greatest possible number within the mean absolute deviation?
Answer:
Infinity
Step-by-step explanation:
The given parameters are;
The mean of the data, μ = 124
The mean absolute deviation = 38
The mean absolute deviation is given as follows;
[tex]Mean \ absolute \ deviation = \dfrac{\sum \left | X - \mu \right |}{N} = 38[/tex]
Where;
μ = Mean
X = Score
N = The number of scores
Therefore;
[tex]N \times 38 = \sum\limits_{i = 1}^N \left | X - \mu \right |} = \sum\limits_{i = 1}^N \left | X -124 \right |}[/tex]
When there are an infinite number of terms, N = ∞, the greatest possible number within the mean absolute deviation is therefore also infinite
[tex]\infty \times 38 = \sum\limits_{i = 1}^{\infty} \left | X - \mu \right |} = \infty[/tex]
[tex]Greatest \ possible \ value \ for \left | X - \mu \right |} = \infty[/tex]
