Answer:
|3-8|-(12/3+1)2
=|-5|-(4+1)2
=5-5x2
=5-10
=-5
You said simplify, but it can be solve.
Answer:
-22
Step-by-step explanation:
4 + 9 + (16 ÷ 4 - 8 - 3) × 5
= 13 + (4 - 8 - 3) × 5
= 13 - 7 × 5
= 13 - 35
= -22
Total number of students surveyed = 200
Number of male students = 80
Number of female students = 200 - 80 = 120
Number of brown eyed male students = 60
Probability of a brown eyed male student = 60 / 80 = 0.75.
Since, <span>eye color and gender are independent, this means that eye color is not affected by the gender. Thus, we expect a similar probability of brown eye for female as we had for male.
Let the number expected of brown eyed females be x, then x / 120 = 0.75.
Thus, x = 120(0.75) = 90.
Therefore, the number female students surveyed expected to be brown eyed is 90.</span>
Someone else asked the same question and got something written out for them. on another site, I found out that the first one was <span>: 8(14.13)=113.04</span>
Answer:
The time spend to burn energy is 3300 minutes .
Step-by-step explanation:
Given as :
The speed at which the bike ride = 10 miles per hours
The energy burn while riding = 550 calories
Let The time spend to burn energy = t minutes
So, According to question
Time spend = 
i.e t = 
hours
∴ t = 55 hours
So, in minutes
The time spend
1 hours = 60 min
∴ 55 hours = 60 × 55 = 3300 minutes
So, The spend to burn energy = t = 3300 minutes
Hence The time spend to burn energy is 3300 minutes . Answer
