Answer:
Mean = 910.2
Standard deviation = 12.8
Step-by-step explanation:
82% over the age of 25 are high school graduates.
A survey randomly selected students of certain country included 1110 who were over the age of 25 and 871 of them were high school.
n = 1110
p = 82% = 0.82
q = 1 - 0. 82
q = 0.18
Mean = np
= 1110*0.82
= 910.2
Standard deviation = √npq
= √ 1110*0.82*0.18
=√163.836
= 12.8
Answer:
x is equal to 106
Step-by-step explanation:
when x is on the opposite side of 2 intersecting lines, it will be the same angle as the angle opposite to it
That means to multiply right? it's 10,800
Answer:
<em>please view graph below</em>
Step-by-step explanation:
I chose to plot the points, since that is a pretty simple graphing method.
X-axis: Game Number
Y-axis: Score
Desmos can help us out on this one.
Points:
(1,97)
(2,109)
(3,102)
(4,114)
(5,100)
(6,133)
(7,103)
(8,115)
(9,128)
(10,101)
(11, 116)
(12, 127)
(13, 117)
(14, 98)
(15, 127)
These plot point create a sort of vertical cos(x) graph.
Hope this helps!
Answer:
Z- 15= -12
Step-by-step explanation:
-2b=6 is incorrect becuase b= -3
4a-5=12 is incorrect because 4a=17.. 17/4=4.25.. A=4.25
5y=y+8 is incorrect because 4y=8.. y=2
Z - 15= -12 is correct because -12+ 15=3... Z=3
