Answer:
13/28
Step-by-step explanation:
Total number of students = 28
Number of students that play basketball = 14
Number of students that play baseball = 19
Number that play neither sport = 5
Number of students playing sports = 28 – 5 = 23
Number of students playing both basketball and baseball = 14 + 19 – 23 = 10
Number of students that play only basketball = 14 – 10 = 4
Number of students that play only baseball = 19 – 10 = 9
Number of students playing basketball or baseball = 4 + 9 = 13
P(a student chosen at random plays basketball or baseball) = 13/28
Answer:
y=4
Step-by-step explanation:
16=4y
divide both sides by 4
4=y
d(x) = { (x,y): y = sqrt(x) and y >=0 }
since sqrt function requires x to be >=0 so
<u>x >= 0</u>
Answer:
54
Step-by-step explanation:
3/(1/2)=6
6x9=54 mi
Thanks and make sure to follow!
F(x) = 9x² - 54x - 19 = 9x² - 57x + 3x - 19 = 3x(3x - 19) + 1(3x - 19)
= (3x - 19)(3x + 1)
f(x) = 0 if 3x - 19 =0 or 3x + 1 = 0
3x = 19 or 3x = -1
x = 19/3 or x = -1/3
