Answer:
d- all students from each grade
Step-by-step explanation:
Answer:
D, all students in each grade.
Step-by-step explanation:
If you did a random sample from the students in the speech club it will be biased because they will probably all say giving speeches because they are in the speech CLUB. You cannot do the teahcers because their answers will also be biased. If you do all the boys in each grade it will be biased only to what boys like and not girls or any other student in the grade. Therefore, using the process of elimination, the answer is D, you should take a random sample of all the students in each grade.
The lowest point on Earth is Challenger Deep, at the bottom of the Marina Trench: 35,797 feet below sea level. The highest point is the summit of Mount Everest: 29,029 feet above sea level. What is the distance, in feet, between Challenger Deep and Mount Everest? Explain your answer.
Answer: 64826 feet
Step-by-step explanation:
The distance, in feet, between Challenger Deep and Mount Everest will be calculated as the difference between the highest point of Mount Everest and the bottom of the Marina Trench. This will be:
= 29029 - (-35797)
= 29029 + 35797
= 64826 feet

Write the equation of the line that has y-intercept of 4 and goes through the points (0,4) & (2.0) (Hint: use those points
to calculate slope first and write answer using y = mx + b)
Answer:
y = -2x + 4
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of a line passing through (0, 4) and (2, 0) will be,
m = [tex]\frac{4-0}{0-2}[/tex]
= -2
Y-intercept of the line 'b' = 4
Therefore, equation of the line will be,
y = -2x + 4
At an automobile factory, 712 parts are made in 3 hours. What is the average rate at which parts are made per hour?
Which shows one way to determine the factors of x3 – 12x2 – 2x + 24 by grouping?
x(x2 – 12) + 2(x2 – 12)
x(x2 – 12) – 2(x2 – 12)
x2(x – 12) + 2(x – 12)
x2(x – 12) – 2(x – 12)
Answer:
D. [tex]x^{2} (x-12) -2(x-12)[/tex]
Step-by-step explanation:
Determine the groups: [tex](x^{3}-12x^{2} )[/tex] - [tex](2x+24)[/tex]
Factor out terms: [tex]x^{2} (x-12) -2(x-12)[/tex]
The -2 was factored out in the second group to ensure that both groups had
(x-12).

Toby skated from his house to the beach at a constant speed of 888 kilometers per hour, and then skated from the beach to the park at a constant speed of 777 kilometers per hour. The total distance Toby skated was 202020 kilometers, and it took him twice as long to get to the park. Let bbb be the number of hours it took Toby to skate from his house to the beach, and ppp the number of hours it took him to skate from the beach to the park. Which system of equations represents this situation?
Answer:
8b+7p=20
p = 2b
Step-by-step explanation:
Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance
Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance
So the total distance would be
= 8b + 7p
And, the total km is 20
Now the whole equation would be
8b + 7p = 20
Also it is mentoined that for getting into the park it is twice for getting into the beach
So, it would be
p = 2b
Therefore the system of equations are as follows
8b+7p=20
p = 2b

the number of girls on the school's basketball team decreased by 20% this year. if there were 25 girls on the team last year. how many girls are on the team this year
Answer:
Step-by-step explanation:
okay so to get 10% of 20 you just move the decimal to the right one so 25.0 would become 2.5 then to find 20% of that you multiply by 2 so 2.5 x 2 = 5 so that means the team lost 5 girls. 25-5=20 therefor there are 20 players on the team this year
