Answer:
Yes, it is a right angle triangle
Step-by-step explanation:
Let leg lengths be y and z
Y = 2mm
Z = 2.1mm
Let x represent hypothenus
X = 2.9mm
To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)
x² = y² + z²
x² = 2² + 2.1²
x² = 4 + 4.41
x² = 8.41
Take the square root of both sides
x = √(8.41)
x = 2.9mm
Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle
Answer:
y = - 4x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , thus
y = - 4x + c ← is the partial equation
To find c substitute (- 4, 6) into the partial equation
6 = 16 + c ⇒ c = 6 - 16 = - 10
y = - 4x - 10 ← equation of line
b - is a part of segment = 9.
We can see that
9 =b + x
b+x+b =12 -----> 2b + x =12
b +x=9 /*(-2) ------> -2b - 2x = -18
2b+x=12
-2b - 2x = -18
<u> 2b + x = 12</u>
-x = -6
x = 6
A- the answer is 2, because it has the most amount of crosses or is the highest bar, showing that it is the most popular (mode)
mean is adding all the numbers divided by how many numbers there are, so 20/10=2
median is the number in the middle of an (ordered) row. but since the numbers are already ordered, it is in between 33 and 35, so the median is 34
C and D since they both show the most and least popular result, rather than estimating percentages.
D because each sample adds up to 200.
