Answer:

99.7%

Step-by-step explanation:

Bell shaped curve by empirical rule is that if the standard deviation from the mean (left to right) is 1 deviation then about 68% of the data is in that range if it’s 2 standard deviations away then it’s 95% and 3 deviations away is 99.7%

142-100=42=3(14)

100-58=42=3(14)

Therefore the data is three standard deviations from the mean and this there is 99.7% of the data in this range.

d = 16.76 inches

Step-by-step explanation:

We can extend the definition of the Pythagorean theorem to 3-dimensions:

d =  \sqrt{ {x}^{2} +  {y}^{2}  +  {z}^{2}  }

Let x = 10 in

y = 10 in

z = 9 in

d =  \sqrt{ {(10)}^{2} +  {(10)}^{2}  +  {(9)}^{2}  }

d =  \sqrt{281}  = 16.76 \: in

How do I solve this absolute value in quality problem <br><br> |2t + 2/3|≤4
xenn [34]

Answer: -7/3≤t≤5/3

Step-by-step explanation:

|2t + 2/3|≤4

2t + 2/3≤4

(2t + 2/3≤4)*3

6t+2≤12

6t≤10

t≤10/6

<u>t≤5/3</u>

2t + 2/3>=-4

(2t + 2/3>=-4)*3

6t + 2>=-12

6t>=-14

t>=-14/6

<u>t>=-7/3</u>

-7/3≤t≤5/3

John translated parallelogram ABCD using the rule (x,y)→(x+3, y−2). If angle A is 110° and angle B is 70°, what is the degree me
bearhunter [10]
Answer: 110 degrees

Angle measurements are preserved when translations happen. Shifting a figure will not change the angle. So because angle A = 110 degrees, this means angle A' = 110 degrees as well.
