The probability that the marble she chooses is not blue can be solve in two ways.
first way: is to solve the probability of red and yellow marbles, so that is the probability of not getting blue
P = 6 + 8 / 6 + 8 + 18P = 7/16
2nd way: is to solve the null of blue or 1 minus the probabilty of choosing blue marble
P = 1 - (18 / 6 + 8 + 18)P = 1 - ( 9 / 16)P = 7/16
Answer:
(-5,-25) that is the image
Step-by-step explanation:
Slope is 3/2
using the rise / run
you don’t 2 points on the line and count how many squares are i between them
so it is up 3 and over 2
We know that
tan²(A)+1 = sec²(A)--------> tan²(A)= sec²(A)-1
tan²(A)= (4/3)²-1------> tan²(A)=16/9-1-----> 7/9
tan²(A)=7/9
if the angle A is in the IV quadrant
then
tan (A) is negative
therefore
tan (A)=-√(7/9)-----> tan (A)=-√7/3
so
cot (A)=1/tan(A)------> cot (A)=-3/√7----> -(3/7)*√7
the answers are
a) the identity is tan²(A)= sec²(A)-1
b) tan (A)=-√7/3
Answer:
c
Step-by-step explanation:
car are a capital gain so it would be c
