Negative 10 and positive 10
Answer:
Less than 100. Z=83
Step-by-step explanation:
The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.
100 =(101+116+Z)/3
300=217+Z
83=Z
Answer:
a) green: 0.3
yellow: 0.1
b) 12
Step-by-step explanation:
Unfortunately, I cant write on the table. But, I CAN help you with this question.
Since all probabilities have to add up to one, we can for an equation like this
(where y is yellow)
0.35+0.25+3y+y=1
This simplified is
0.6+4y=1
4y=0.4
So, we now know that green is 0.3, and yellow is 0.1.
For b, we set 0.35x to 14. Dividing gives us:
14/0.35=1400/35=40.
Multiply 0.3 by 40, and you get 12.
Hope this helped!
Answer:
$505.385
Step-by-step explanation:
Given that:
Worker's one month salary is 4380
The number of working days in the month is not given ; However the average number of working days in a month usually range from 22 to about 26 days
Lets assume the number of working days for the firm in question is 26 days
Daily salary will be calculated as :
Monthly salary / number of working days
4380 / 26
= 168.46153
3 days salary :
168.46153 * 3
= $505.385

Step-by-step explanation:
Area = area of rectangle 1 + area of rectangle 2 + area of rectangle 3 +area of triangle
= 8*12 + 12*9 + 19 *5 + (1/2) * 4 *12
= 96 + 108 + 95 + 24
= 323 sq. cm
