Answers
Answer:
Approximately normal
Mode: 4
Range:9
Step-by-step explanation:
The data is pretty evenly spread, the data isn’t pushed to the left or right giving the answer of approximately normal.
Mode: The number that occurs the most is the mode. This means that 4 would be the answer because it has the most dots.
Range: To find the range subtract the smallest number from the biggest number. In this case you would get 9-0 (this is because no data is recorded for 10) which equals 9.

Solve each equation and show all work plis 115 = -6k - 5
Answers
Answer:
Answer: k = - 20
Step-by-step explanation:
Solution
115 = -6k - 5 Add 5 to both sides
115+5 = - 6k - 5+5 Combine
120 = - 6k Divide by - 6
120/-6 = -6k/-6
-20 = k
Answer: -20
Step-by-step explanation:115 = -6k-5
Add5 to both sides
120= -6k
Divide both sides by 6
20= -k
K = -20

=
O 42+ b2 = 52
O 42-62 = 52
O 52 +42 – 52
Answers
Answer:
this question isn't quite clear, is the diagram of the triangle necessary for me to answer this question ?
Step-by-step explanation:
but by simple analysis,
since the "unknown" is b
option (a) which is 42 + b2 = 52 is the best equation.
because we are looking for the value of "b", therefore there should be letter "b" in equation we're going to use. hope you understand...

How do you solve for 4, 5, or 6?
Answers
Answer:
see images
Step-by-step explanation:
For all of these questions it helps to know the special right triangle, the 30°-60°-90° triangle. There is a special shortcut to find the sides of the 30°-60°-90° triangle.
For question4 and 5, these are equilateral triangles so the angles are all 60° So if you drop the height, it makes two 30°-60°-90° triangles. ***The short leg is HALF the hypotenuse or the hypotenuse is DOUBLE the short leg. The long leg is the short leg × sqroot3.***
This shortcut, special rt triangle info is used in all three of your questions. See image. Then you will have base and height or the apothem and side length for the Apothem Area formula:
A = 1/2 a•s•n
where a is the apothem, s is the side length and n is the number of sides. It looked like you already used this formula. See image.

Answers
Answer:
A) 2.1/6.3 = 8.7/X
Step-by-step explanation:
If two rectangles are similar, the ratio of the two shorter sides should equal the ratio of the two longer sides.
The two shorter sides are 2.1 cm and 6.3 cm
The two longer sides are 8.7 cm and X.
Therefore, as ratios:
2.1 : 6.3 = 8.7 : X
⇒ 2.1/6.3 = 8.7/X

Answer:
Step-by-step explanation:
2πrh+2πr^2 is the formula for finding the surface area of a cylinder.
Since the question said to use 3.14 for pi,
2 * 3.14 * 4* 7 + 2*3.14*16

C. a triangle that must have same dimensions as one of the faces
D. a triangle that does not have the same dimensions as one of the faces
Answers
Answer:
B. a rectangle
Step-by-step explanation:
A cross section is the new face you see when you slice through a 3D figure. So if you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross section. Similarly, if you slice parallel to a triangular base then your cross section will be a triangle.
Hope this helps and God bless!

I think Its D because In the rectangular base its not equal sides like a square so it would be more be like sides that are not perpendicular.

Answer: a+51=90, a+51+90=180, 39
Step-by-step explanation:
a+51=90 works because the angles add to form a right angle.
a+51=180 does not work because the angles add to form a right angle, not a straight angle.
a+51+90=180 works because all those angles add to form a straight angle.
a+90=180 does not work because the unknown in this situation refers to a+51, not just a.
Solving the equation, we get a=39, so 39 is also an answer.

Answers
Answer:
B. y = -x – 1
Step-by-step explanation:
calculate slope =
y2-y1 = -5- (-2) = -3
x2-x1 = 4 - 1 = 3
m (slope) = -3/3 = -1
using points (1,-2) for calculating y-intercept:
y = mx + b
-2 = -1(1) + b
-2 = -1 + b
-1 = b
b = -1

2.If 34 x 27 = 918, which of the following is true?
918 ÷ (-34) = 27
-918 ÷ 34 = -27
-918 ÷ 27 = 34
918 ÷ 27 = -34
3. Dividing by a negative number will give a negative quotient.
True
False
Answers
Answers:
1: Option B: It is positve
2: Option B: -918 ÷ 34 = -27
3: Option B: False
( if the questions context is ONLY talking about dividing positives by a negative then its true, else if they are talking about ANY circumstance, even if negatives are divided by a negative then its false )
Step-by-step explanation:
For question 3:
When you divide a negative number by a positive number then the quotient is negative. When you divide a positive number by a negative number then the quotient is also negative. When you divide two negative numbers then the quotient is positive. The same rules hold true for multiplication.
