Answer:
a) "engaged" is a quantitative and continuous variable.
b) The sample proportion of students in this high school district who are engaged is 0.4222
Step-by-step explanation:
Given the data in the question;
Polling reports shows that 0.34 12th grade students are engaged
the principal surveyed 90 of the 3600 students,
number of students reported to be engaged is 38
a)
"engaged" is a quantitative and continuous variable.
b) the sample proportion of students in this high school district who are engaged.
Sample proportion of engaged = number of students reported to be engaged / total number of students surveyed
so
Sample proportion of engaged = 38 / 90
Sample proportion of engaged = 0.4222
Therefore, the sample proportion of students in this high school district who are engaged is 0.4222

325 miles
398 miles
400 miles
406 miles
Answer: 406 miles
Step-by-step explanation: First you have to figure out how many miles he traveles per hour and to do that you divide 174 by 3 to get 58. Then multiply that by 7 because that is the amount of hours he should be traveling to get 406
Answer:
406 miles
Step-by-step explanation:
First find how far Martin can travel in 1 hour, then multiply by 7(hours):
174 ÷ 3 = 58
58 × 7 = 406

If the value of "y" varies directly with "ex"
and y = -8 when x = 20, find "y" if x = -4.
Enter the number that belongs in the green box.
Reduce to simplest form.
y = 2
Answer:
8/5
Step-by-step explanation:
We can use a proportion to solve this question, if we put the values of x on the left of the equal and the value of y on the right we have
20 : -4 = -8 : y
y = (-4*-8)/20
= 32/20
= 8/5

4. Quinn scores 275 points in 5 min on her favorite
video
game. Delilah scores 675 points in 15 min.
If they continue to play at this level, who do you
predict will score 5000 points faster? Explain.
Answer:
Quinn
For Quinn:
275 points - - > 5 min
5000 points - - > x min
--------------------------------------
275*x=5*5000-->x=90.9 minutes
For Delilah:
675 points - - > 15 min
5000 points - - > y min
--------------------------------------
675*x=15*5000-->y=111.1 minutes
90.9<111.1, so Quinn will score 5000 points faster
Verify the identity.
Please show your work.
Step-by-step explanation:
To prove :
( 1 - sin x ) ( 1 + sin x ) = sec² x
LHS : -
( 1 - sin x ) ( 1 + sin x )
Formula / Identity : -
( a - b ) ( a + b ) = a² - b²
Here,
a = 1
b = sin x
( 1 - sin x ) ( 1 + sin x )
= 1 - sin² x
Identify : -
sin² θ + cos² θ = 1
cos² θ = 1 - sin² θ
Similarly,
1 - sin² x
= cos² x
= RHS
Hence verified.

HELP MEEEE PLEASEEEEEE
Answer:
The area of the circle is 27
Step-by-step explanation:
Using the formula given to us, we know that the area of the circle = pi times the radius squared. This gives us an indication of what we need to do. We must first understand that the radius of the circle is 3. Multiply the radius by the 2nd power (multiply 3 by 3), and we get 9. They then ask us to substitute 3 for pi, meaning instead of pi times 9, it's 3 times nine, and 3*9=27. And there is your answer.

Find the midpoint of the segment with the following endpoints (7-6) and (4-10)
Answer:
(5.5,2)
Step-by-step explanation:
Find the midpoint of the segment with the following endpoints (7-6) and (4-10)
The formula for calculating the x and y coordinate is expressed as
X = x1+x2/2
X = 7+4/2
X = 11/2
X = 5.5
Y = y1+y2/2
Y = -6+10/2
Y = 4/2
Y = 2
Hence the required midpoint is at (5.5,2)

The correct expression for a number which is 9 times as big as the number obtained after p has been increased
by 4
Answer:
9(p + 4)
Step-by-step explanation:
One of the unknown variable is p.
First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).
Translating the word problem into an algebraic expression, we have;
9 * (p + 4) = 9(p + 4)
Simplifying further, we have;
9p + 36
