1:
A - actually not true, a probability plot would be better
B - not true, since exact values are plotted a box-and-whisker would be better
C - true (that's what a histogram does)
D - True (You can get the measures of central tendency quickly)
2:
A - true
B - False - those are easily found
C - False - They are arranged on the x-axis
D - True - see above
Answer:
t=4 seconds
Step-by-step explanation:
The height of the water jacket that is projected vertically upward is given by the equation:
We want to find the time that, the rocket reaches the ground.
When the rocket reaches the ground, the height , h becomes 0.
This implies that:
Subtract 20 from both sides:
Divide through by -5;
Take square root:
l
Therefore the feasible time is after 4 seconds.
There are only 9 single digit numbers from 1-50: (1, 2, 3, 4, 5, 6, 7, 8, 9)
To find the percent, we divide 9 by 50
9/50=0.18
Now, we multiply our answer by 100
0.18(100)=18%
There’s an 18% chance of pulling a single digit number out of a jar with numbers from 1 to 50
Answer:
Option A. 52°
Step-by-step explanation:
From the figure attached,
JEFH is a parallelogram and ΔFGH is a scalene right triangle.
If m∠JEF = 142°
m∠JHF = 142° [Since opposite angles of the parallelogram are equal]
m∠FHG + m∠JHF = 180°
m∠FHG + 142° = 180°
m∠FHG = 180 - 142
= 38°
In the given scalene right triangle FGH,
m∠FHG + m∠HFG + m∠HGF = 180°
38° + m∠HFG + 90° = 180°
m∠HFG = 180° - 128°
m∠HFG = 52°
Option A. will be the answer.
Answer: x=17
Step-by-step explanation:
7x + 15 = 4x + 66 Subtract 4x from both sides
-4x -4x
3x + 15 = 66 subtract 15 from both sides
-15 -15
3x = 51 Divide both sides by 3
x= 17
