What is the polynomial function of lowest degree with leading coefficient of 1 and roots 3, 4, and 4? O f(x)= x - 3x + 16x + 48
O f(x)=x2-3x2 - 16x = 48
O f(x)= x4 -19x +48
O f(x)= x4 – 13x2 = 48​

i believe the answer is letter c) 8

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
