Answer:

Middle 95​% of the​ women's heights​ lie between 59.1 inches and 64.9 inches

Step-by-step explanation:

According to the 68-95-99.7 rule ,

  • 1 standard deviation around the mean includes middle 68% of the population
  • 2 standard deviation around the mean includes middle 95% of the population
  • 3 standard deviation around the mean includes middle 99.7% of the population

Therefore Middle 95​% of the​ women's heights​ lie 62±2.9 inches according to the study. That is between 59.1 inches and 64.9 inches.

B. If some amount of water contains 1400 oxygen atoms, how many hydrogen atoms does it contain?
Genrish500 [490]

Answer:

B: 2800 hydrogen atoms

C: 6760 hydrogen atoms

D: y=amount of oxygen atoms*2

Step-by-step explanation:

B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.

C: Same thing as B. 3380*2=6760

D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.

In terms of rigid transformations (reflections, rotations, and translations), what does this difference represent?
makvit [3.9K]

Solution:

There are four kinds of rigid transformations.

1. Reflection

2. Rotation

3. Translation

4. Dilation

1.  The Meaning of term reflection is when we reflect something through a line or mirror the distance of object from line of reflection on both sides are same. The two images Preimage and image are congruent.

2.   Rotation means rotating an object or geometrical shape through an angle. An angle can be of any measure that is 0,30°,45°,90°,...... In rotation the two , image and preimage are congruent.

3.  While in translation , we shift something from a place to another place keeping the two images,that is image and preimage are congruent.

In all three,either in  reflection, rotation,or  translation  there is no change in shape and size, the two that is  image and Preimage are congruent.

What is 1/10th of 2,871,000?
abruzzese [7]
This is fairly simple. Divide 2,871,000 by 10 and that's your answer!

\frac{2,871,000}{10} =287,100

Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.
