Answer:
The equation of the line would be y = 1/8x - 3
Step-by-step explanation:
to find the slope intercept form of the line, you must first find the slope. You can do this using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-2 - -4)/(8 - -8)
m = 2/16
m = 1/8
Then you can use this slope along with either point in point-slope form. Then solve for y.
y - y1 = m(x - x1)
y + 4 = 1/8(x + 8)
y + 4 = 1/8x + 1
y = 1/8x - 3
Answer:
The probability that she will have breast cancer is 0.2375.
Step-by-step explanation:
P(Positive if no Cancer) = 86.6/1000 = 0.0866
P(Positive if Cancer) = 1 − 1.1/1000 = 0.9989, and
P(Cancer) = 1/38 = 0.0263
If a woman between the ages of 50 and 59 has a positive mammogram, the probability that she will have breast cancer will be calculated by using the Bayes rule.
Bayes’s theorem describes the probability of an event.
P(Cancer if Positive) = 
= 
= 0.2375
Answer:
2x - y = - 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2 , then
y = 2x + c ← is the partial equation
to find c substitute (- 1, 1 ) into the partial equation
1 = - 2 + c ⇒ c = 1 + 2 = 3
y = 2x + 3 ← in slope- intercept form
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
rearranging the slope- intercept form of the equation from above
2x + 3 = y ( subtract y from both sides )
2x - y + 3 = 0 ( subtract 3 from both sides )
2x - y = - 3 ← in standard form
I can help, just ask the question a little better
18 cm and 24 cm because you need to multiply each length by the same number and in this case, 3 works. 6x3=18 and 8x3=24
