Answer:
To the right we have 62.6 while to the left we have 49.4
Step-by-step explanation:
A normal distribution is usually symmetric with respect to the mean. The mean of the distribution is also the mode as well as the median.
The general formula for points that lie n standard deviations away from the mean on either sides of the mean is given by the formula;
mean ± n(σ)
where σ is the standard deviation of the distribution;
Two standards deviations from the mean imply that n = 2;
56 ± 2(3.3)
56 ± 6.6
To the right we have 62.6 while to the left we have 49.4

Answer:
a. 12 cm
b. 90°
c. 60°
Step-by-step explanation:
The relevant relationships are ...
- all sides of a rhombus have the same length
- the diagonals of a rhombus are perpendicular bisectors of each other
- the diagonals of a rhombus divide the figure into 4 congruent triangles
__
a) The perimeter, 48 cm, is the sum of four equal side lengths, so any given side is (48 cm)/4 = 12 cm.
GH = 12 cm
__
b) Angle EJF is where the diagonals meet. It is a right angle.
∠EJF = 90°
__
c) Angle EFJ is the complement of the one marked, so is 30°. Angles EHJ and GHJ are congruent to that, so both are 30°. Angle EHG is the sum of those two congruent 30° angles, so is ...
∠EHG = 60°
