What is a unique characteristic of a set of data that is distributed normally?
A. the mean is greater than the median
B. the mean is less than the median
C. the mean is the same as the median
D. the data set does not have a median
Answer:
C
Step-by-step explanation:
Normal distribution has a unique characteristic of having equal mean and median values. If mean was higher than median, then the distribution would be positively skewed. Mean lower than median would appear in distributions negatively skewed. Each data set has a median value.
In a cafeteria, 1 10 of the students are eating salads , and 2 5 are eating sandwiches. There are 20 students in the cafeteria. How many students are eating lunches other than salads or sandwiches?
Answer:Number of students eating lunches other than salads or sandwiches= 10
Step-by-step explanation:
Number of students in the cafeteria=20
Number of students eating salads=1/10 X 20= 2
Number of students eating sandwiches= 2/5 x 20 = 8
Number of students eating lunches other than salads or sandwiches=
Number of students in the cafeteria -(
Number of students eating salads +Number of students eating sandwiches)
=20-(2+8)
=20-10
=10 students.
A right cubic prism has edges of 2 1/2 inches. How
many cubes with side lengths of inches would
be needed to fill the prism?
A. 125 cubes
B. 37.5 cubes
C. 18.75 cubes
D. 15.625 cubes
Answer:
Option D, the volume is 15.625 cubes
Step-by-step explanation:
For a cube of side length L, the volume is:
V = L^3
for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:
v = (1in)^3 = 1 in^3
Then:
1 in^3 is equivalent to one small cube
Here we know that the side length of our cube is (2 + 1/2) in
Then the volume of this cube will be:
V = [ (2 + 1/2) in]^3
To simplify the calculation, we can write:
2 + 1/2 = 4/2 + 1/2 = 5/2
Then:
V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3
This means that 15.625 small cubes will fill the prism.
So the correct option is D.

In ΔQRS, the measure of ∠S=90°, SQ = 9.7 feet, and RS = 1.3 feet. Find the measure of ∠R to the nearest degree. (please answer asap)
Answer:
82
Step-by-step explanation:
A mailing supply company produces yellow mailing envelopes. The envelopes come in
a variety of sizes, but the length is always 4 centimeters more than double the width.
Write an equation to find the dimensions of an envelope that has a perimeter of 26
centimeters.
Answer:
Step-by-step explanation:
L=2W+4
P=2(L+W), using L from above makes this
P=2(2W+4+W)
P=2(3W+4)
P=6W+8
6W=P-8
W=(P-8)/6, since we are told P=26
W=(26-8)/6
W=18/6
W=3 cm, and since L=2W+4
L=2(3)+4
L=6+4
L=10 cm
So the dimensions of the envelope with a perimeter of 26cm is 3cm by 10cm
In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use? Laws of Sines or Laws of Cosines? and why?
Answer:
We would use the Law of Cosines to solve the question.
m∠ W = 121.8°
Step-by-step explanation:
In triangle UVW, u = 20, v = 47. and w = 60. To find m∠ W,
which law would you use?
The Law we would use to find find m∠W is the Law of cosines, this is because in the question above we are given 3 known sides of a triangle and we are asked to find an unknown angle.
Law of cosines when we are to find an unknown angle =
m∠ W = arc cos [u² + v² - w²/ 2uv]
m∠ W = arccos [ 20² + 47² - 60²/ 2 × 20 × 47]
m∠ W = 121.81159°
Approximately = 121.8°

Answer:
g(x) = [tex]2^{x}[/tex] + 3
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here the shift is 3 units up, then
g(x) = [tex]2^{x}[/tex] + 3
A dilation has center (0,0). Find the image of the point L(6-8) for the scale factor 7.
Answer:
D (42,-56)
Step-by-step explanation:
Scale factor means you multiply, so you multiply (6,-8) by 7.
6 x 7 is 42 and 7 x -8 is -56. So your answer is D (42,-56).

bongani is driving at a speed of 63 km/h. how far will he travels ( 4,5hours )
Answer:
283.5km
Step-by-step explanation:
Given data
Speed= 63km/h
Time= 4.5hours
We know that speed= Distance/time
Make distance subject of the formula
DIstance= speed*time
Distance= 63*4.5
Distance= 283.5km
Hence the distance is 283.5km

At x = -2, y = 3
(-7, y) and (-2,-4); m = -6/5 find the slope
Answer:
y = 2
Step-by-step explanation:
Use the slope formula so y2-y1/x2-x1 = -6/5
so -4 - y / -2 + 7 = -6/5 so y has to be 2 so that -4-2=-6

Which of these figures is NOT a quadrilateral?
Answer:
the correct answer is A
step by step explanation
Figure A is NOT a quadrilateral. Then the correct option is A.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees. In a quadrilateral, there are four vertices.
A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. In a rhombus, opposite sides are parallel and all sides are equal. In a parallelogram, opposite sides are parallel and equal.
Figure A is NOT a quadrilateral. Because two corners of the figure are rounded and in the quadrilateral, all the vertices are shaped.
Figure A is NOT a quadrilateral. Then the correct option is A.
