Answer:
- 5-hour: 0.5277
- 1-hour: 0.8800
Step-by-step explanation:
The decay factor for time t can be written as ...
0.2785^(t/10)
Then the 5-hour decay factor is ...
0.2785^(5/10) ≈ 0.5277
and the 1-hour decay factor is ...
0.2785^(1/10) ≈ 0.8800
8x6= 48 (not necessary to divide by 8 since you'd have to multiply it by 2 anyway because there are 2 triangles)
6x12=72
10x12=120
12x8=96
48+72+120+96=336
336cm^2 is the answer
Answer:
224 cm³
Step-by-step explanation:
Decompose the figure into two cuboid.
Volume of the bigger cuboid = L*W*H
L = 7 cm
H = 7 cm
W = 4 cm
Volume of the bigger cuboid = 7*7*4 = 196 cm³
Volume of smaller cuboid = L*W*H
L = 7 cm
W = 2 cm
H = 2 cm
Volume of smaller cuboid = 7*2*2 = 28 cm³
✅Volume of the figure = 196 cm³ + 28 cm³ = 224 cm³
Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
