Answer:
8 times 2 is 16 so its probly 2 imk if my wrong
Answer: Thats a question for the pro's
Step-by-step explanation:
Dude im a very smart programing 8th grader but i have no idea how to do this
a) cannot be determined.
b) Steel
c)Steel
d)Steel
e) Wooden coaster is slower than Steel, Both of them are normally distributed as median are at the center of the box plot. Steel has a greater variability than wooden as the whisker stretch.There no outliers in the box plot as only whiskers are available.
Step-by-step explanation:
- a)cannot be determined, as it shows only the variability of data.
- a)Picture or a graph only shows the decision of data not data points.
- b)Steel because Median of Steel goes from 60 mph to 100 mph.
- c)Steel because the 1st quartile for wood and steel starts at 50.
- c)Steel goes beyond 50 to 100 mph.
- d)Steel goes 48mph as both wooden and Steel are starting at whiskers.
- d)Steel Whiskers are ending at 100.
- e) Both of the them are normally distributed as median at the center.
- Whiskers are higher for steel as it goes faster then wooden.
- Wooden starts faster then Steel as whiskers dont start fast.
- Wooden is whisker is closer to 50 steel closer to 60.
- There is no outliers as no extreme values.
The answer is y = 2x + 3.
x - Kay's age
y - Jane's age
m - Mary's age
<span>Jane is 3 years older than Mary: y = m + 3
</span><span>Mary is twice as old as Kay: m = 2x
</span><span>
y = m + 3
m = 2x
Substitute m in the first equation:
y = 2x + 3
</span>
Answer:
7. one triangle
8. two triangles
Step-by-step explanation:
When you are given two sides and one of the opposite angles, you can make a determination as follows:
- If the given angle is <em>opposite the longest given side</em>, there is one solution.
- If the given angle is <em>opposite the shortest given side</em>, there may be 0, 1, or 2 solutions.
For the latter case, the possibilities for sides b, c, and angle C are ...
C > 90° . . . . . . . . no solution
(b/c)sin(C) > 1 . . . no solution
(b/c)sin(C) = 1 . . . 1 solution
(b/c)sin(C) < 1 . . . 2 solutions
(The expression (b/c)sin(C) gives sin(B), so the value must lie within the range of the sine function in order for there to be any solution.)
_____
7. The given angle is opposite the <em>longest</em> given side. There is one solution.
__
8. The given angle is opposite the <em>shortest</em> given side, so we compute
(b/c)sin(C) = (34/28)sin(20°) ≈ 0.41
This is less than 1, so there are two solutions.
