Answer:
y=-3x+5
Step-by-step explanation:
So, with perpendicular equations, you flip the slope, so 1/3 becomes 3/1, and make it negative, and if it is already negative, you make it positive. So, since we have the slope, move on to the b=y-mx, so b=-4-(3)(-3), multiply to get b=-4-(-9), which makes our y-int 5.
Answer:
the answer is the last one. hope this helped.
Step-by-step explanation:
If you Measure both sides it will be the same so the answer is 40
The 68-95-99.7 rule tells us 68% of the probability is between -1 standard deviation and +1 standard deviation from the mean. So we expect 75% corresponds to slightly more than 1 standard deviation.
Usually the unit normal tables don't report the area between -σ and σ but instead a cumulative probability, the area between -∞ and σ. 75% corresponds to 37.5% in each half so a cumulative probability of 50%+37.5%=87.5%. We look that up in the normal table and get σ=1.15.
So we expect 75% of normally distributed data to fall within μ-1.15σ and μ+1.15σ
That's 288.6 - 1.15(21.2) to 288.6 + 1.15(21.2)
Answer: 264.22 to 312.98
