Answer:
The probability is that he hits 5.6 out of 7 attempts.
Step-by-step explanation:
Given that an archer hits his target 80% of the time, if he shoots 7 arrows, to determine what is the probability of each event, the following calculation must be performed:
7 x 80/100 = X
560/100 = X
5.6 = X
Therefore, the probability is that he hits 5.6 out of 7 attempts.
Answer:
-2x is the slope, the full equation is y=-2x+.5.
Step-by-step explanation:
y=-2x+.5
Answer:
Step-by-step explanation:
If a line is parallel to another it must have the same slope
The slope/intercept form of a line is y = mx + b where m is the slope and b the y intercept
The line y = 2x + 5 has slope 2
So the slope of the line that passes through (2,3) must also have the slope 2
We have
y = 2x + b; Substituting x =2, y =3 in this equation gives us
3 = 2 (2) + b or b = -1
Hence the equation of the line is
y = 2x -1
Cross-check
Substitute for x = 2 ==> y = 2(2) - 1 = 3 which is consistent
