Answer:
b=11.6m
Step-by-step explanation:
If this is a right triangle;
a^2+b^2=c^2
A and B are both LEGS, while C is the HYPOTENUSE
(8.7^2)+b^2=(14.5^2)
b^2=(14.5^2)-(8.7^2)
b^2=134.56
b=plus or minus 11.6
Because length can't be negative, it's +11.6
The general form of a quadratic equation is that which is expressed in a form,
ax² + bx + c = 0
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice.
Answer: 6 divided by 5 is 1.2
Step-by-step explanation: I used Siri lol
{ 3x-2y=2
{ y=2x+8
{ -2y=2-3x
{ y=2x+8
{ y= -1+3/2x
{ y= 2x+8
-1+3/2x = 2x+8
x=-18
y= 2(-18)+8
y= -28
(x,y) = ( -18,-28)
——
Solution check
{ 3(-18)-2(-28)=2
{ -28=2(-18)+8
{ 2=2
{ -28=-28
Answer:
1.242% probability that the second one selected is defective given that the first one was defective
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
We have
484 containers
7 are defective
a) What is the probability that the second one selected is defective given that the first one was defective?
After the first one was selected(defective), we have
483 containers
6 defective
6/483 = 0.01242
0.01242 = 1.242% probability that the second one selected is defective given that the first one was defective
