Which of the quadratic functions has the narrowest graph?
A. y = 1/9x2
B. y = –x2
C. y = 1/4x2
D. y = 4x2
Answer:
D: y = 4x^2
Step-by-step explanation:
The graph for which the absolute value of the coefficient of x is largest has the narrowest graph. That takes us immediately to D: y = 4x^2.

Answer: 11 goes in the blank in the denominator
The probability as a fraction is 5/11
============================================================
Explanation:
There are 250 red and 300 blue. This gives 250+300 = 550 total marbles.
Divide the number of red (250) over the number total (550) to get the fraction 250/550. Reduce this fraction by dividing both parts by 50. Note how 50 is the GCF of 250 and 550.
Let A = 250 and B = 550.
A/GCF = 250/GCF = 250/50 = 5 which is the numerator already written for usB/GCF = 550/50 = 11 will go in the blank in the denominatorThe fraction A/B = 250/550 fully reduces to 5/11.
We can think of it like saying "There are 5 red marbles out of 11 total".
5/11 = 0.4545 = 45.45% approximately

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?
Answer:
40 waves
Step-by-step explanation:
Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%
Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40
Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.PLEASE HELP ASAP WIL GIVE BRAINLYEST AND REPORT

Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?
Answer:
There are 25 students in the class.
Step-by-step explanation:
Let the total number of students in the class= x
No. of students who passed the test = 18 = 72% of x = 72x/100
Therefore, 72x/100=18
=72x=18*100=1800
=x=1800/72= 25 students.
Hence, total number of students in the class= 25 students

d = 12.25
Step-by-step explanation:
d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(-1, 7, -10)
Substitute the values in the above equation and you will get
d = √(-1 - 0)^2 + (7 - 0)^2 + (-10 - 0)^2
= √(1 + 49 + 100)
= √150
