Answer:
30 Students
Step-by-step explanation:
As given
Bill is in a class of 15 boys and 35 girls.
Total number of students in the class = Number of boys + Number of girls
= 15 + 35
= 50
As given
40% of the students in the class take the bus to school.
40% is written in the decimal form.
= 0.40
Number of students take bus to school = 0.40 × Total students in class.
= 0.40 × 50
= 20
.Thus
Students not take bus to school = Total students - Number of students take bus to school
= 50 - 20
= 30
Therefore 30 students not take bus to school .
Answer:
15 students
Step-by-step explanation:
First of we have to calculate how many students there are in the class. There are 15 boys and 10 girls, whish means there are 25 people in total (15+10=25).
Since 40% takes the bus to school, 60% of the sudents do not take the bus to school. The easiest way to calculate how many students is 60% is to first divide the students with 10. 25/10 is 2.5. 2.5 students is 10% of 25 students (100% divided by 10 is 10%).
To get 60%, the number of students has to be multiplied with 6, because 10% times 6 is 60%.
2.5 (10%) times 6 is 15, so the answer is 15.
X=7
Parallel, perpendicular, or neither
Answer: Parallel.
Step-by-step explanation:
Because both points run across the x-axis, never cross, and are in straight lines, the points would be known as parallel to one another.
The probability that all 7 solar cells will be active is 0.08243, or approximately 8.24%.
In this question, we are given that each solar cell on the satellite has a failure probability of 0.3. Since there are 7 cells, we need all of them to be active in order to have adequate power output for the mission. To find the probability of this happening, we need to calculate the probability of all 7 cells being active.
Since each cell operates independently, the probability of a cell failing is 0.3 and the probability of it being active is 1 - 0.3 = 0.7. Therefore, the probability that all 7 cells will be active is (0.7)^7 = 0.08243.
Thus, the probability of there being adequate power output for the mission is 0.08243, or approximately 8.24%.

Simplify both sides of the equation
-5/2 x +3/4 x = -3/4
Combine like terms
(-5/2 x + 3/4 x )
-7/4 x = -3/4
-7/4 x = -3/4
Multiply both sides by 4/(-7)
(4/-7)*(-7/4 x ) = (4/-7 ) * ( -3/4 )
x = 3/7
Answer:
Step-by-step explanation:
in total there is 6x
180/6=30
x=30
2x=60
3x=90
Answer:30°
Step-by-step explanation:
Thera are 3 angles in a triangel. The sum of all angles is 180°
x+2x+3x=180
6x=180
x=180/6=30
