Answer:
7.5 hours
Step-by-step explanation: You know that at a rate of 52 miles per hour on a highway. Aunt is 390 miles away. Divide 390 by 52 and you get 7.5. So it will take Ms. Wilson 7.5(7hr 30 min) to see her beloved aunt.
Answer:
0.7557
Step-by-step explanation:
In this question use the Table of Standard Normal Probabilities for Negative z-scores and the Table of Standard Normal Probabilities for Positive z-scores
Where z=2.27 NORMDIST(2.27)=0.9884 (read from table for positive z-scores)
Where z=-0.73 NORMDIST(-0.73)=0.2327 (read from table for negative z-scores)
You know P(-0.73<z<2.27)= 0.9884-0.2327=0.7557
Answer:
both functions have the same graph
Step-by-step explanation:
The first function is described in terms of its slope and y-intercept, so can be written in slope-intercept form as ...
y = mx + b . . . . m = slope (-7/9); b = y-intercept (3)
y = -7/9x +3
__
The second function is written in point-slope form:
y -k = m(x -h) . . . . m = slope (-7/9), point = (h, k) = (18, -11)
y +11 = -7/9(x -18)
If we rearrange the second equation to the form of the first, we get ...
y = -7/9x +14 -11 . . . . eliminate parentheses, subtract 11
y = -7/9x +3 . . . . . . . matches the equation of the first function
__
Both functions describe the same relation.
Answer: slope = -1
Step-by-step explanation:
Count from point (2,0) to point (0,2)
You get 2/2 which simplifies to 1.
However the line is negative so the slope must be negative, giving you a slope of -1 as your final answer.
