If you subtract 3-7 and add 9 to it the result is 5. 3-7+9=5
Answer:
Commutative property of addition, or just commutative property.
Step-by-step explanation:
The commutative property states that the order of numbers in addition does not matter, which is shown in the problem.
In 5 years, the investment will be worth 5000(1 + 0.12)^5 + 5000(1 + 0.02/2)^(5 * 2) = 5000(1.12)^5 + 5000(1.01)^10 = 8811.71 + 5523.11 = $14,334.82
Answer:
As a statistical tool, a frequency distribution provides a visual representation for the distribution of observations within a particular test. Analysts often use frequency distribution to visualize or illustrate the data collected in a sample.
Step-by-step explanation:
Sol
Given that ,
mean =300
standard deviation =a =70
n=100
ux=128
a ) within 6 =300 +/-6 : 294, 306
P(294' ' 306)
: P(-0.86 : Z ' 0.86)
: P(Z ' 0.86) - P(Z ' -0.86)
Using z table,
: 0.8051-0.1949
: 0.6102
Probability : 0.6102
a ) within 18 =300 18 : 294, 318
P(294' ' 306)
: P(Z ' 2.57) - P(Z ' -2.57)
Using z table,
:0.9949-0.0051
:0.9898
Probability =0.9898
