Please help me with the answer I keep getting it wrong
1 answer:
First because it's a broken line we know it's an inequality.
next we find the slope we can take points (0,4) and (2,0) thus (y2-y1)÷(x2-x1)
substituting any value of x for either x1 or x2 and any value of y for y1 and y2 we can get
slope is -2
so now we can take either points to find the equation by the formula
y-yo=m (x-xo) where m is slope
after substitution we can get
y-4=-2 (x-0)
y=-2x+4

Account B principle for B=400, principle for A=200
Step-by-step explanation:
1, 3, 3, 4, 5, 6, each x is one of each number below
X= 2.5
just move the terms collect the terms calculate it, divide both sides !!
Answer:
P(A)=0.55
P(A and B)=P(A∩B)=0.1265
P(A or B)=P(A∪B)=0.7635
P(A|B)=0.3721
Step-by-step explanation:
P(A')=0.45
P(A)=1-0.45=0.55
P(B∩A)=?
P(B|A)=0.23
P(B|A)=(P(A∩B))/P(A)
0.23=(P(A∩B))/0.55
P(A∩B)=0.23×0.55=0.1265
P(A∪B)=P(A)+P(B)-P(A∩B)
=0.55+0.34-0.1265
=0.7635
P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721
Step-by-step explanation:
tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.
Therefore 1.6m / (2m + x) = 1/√3
By cross multiplication, 1.6√3 = 2 + x.
Hence, x ≈ 0.77m.
