Answer:
2,9
Step-by-step explanation:
The answer is between $175 and $295. The standard deviation rule tells us that for distributions that have the normal shape, approximately 99.7% of the observations fall within 3 standard deviations of the mean. Indeed, 175 = 235 − 3 * 20 and 295 = 235 + 3 * 20 are exactly 3 standard deviations below and above the mean, respectively.
Answer:
-8/7 slope
Step-by-step explanation:
so first u need to figure out the y=mx+b of ur equation 8x+7y=-28 to make it easier on urself yk. so first you get the y by it self and change it to become 7y= -8x-28 you do this by dragging the 8x to the other side which makes it negative since ur switching sides. now u divide each number by 7 since the 7y is by itself. doing this u get y= -8/7x-4. basically parallel = same slope so you will keep ur same slope or m as -8/7 and now all u need to find is b but in ur question u didnt give coordinates so irdk but ur answer has to have the -8/7 slope
