Answer:
Step-by-step explanation:
By the Pythagorean Theorem we know
(r+7)^2=r^2+14^2
r^2+14r+49=r^2+196
14r+49=196
14r=147
r=10.5
Answer:
1/2
Step-by-step explanation:
The equal distance between 0 and 1 must be one-half or 1/2.
You have to multiply .1 by 10 to equal 1 so it is 10 × greater.
Answer:
0.918 is the probability that the sample average sediment density is at most 3.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2.80
Standard Deviation, σ = 0.85
Sample size,n = 35
We are given that the distribution of sediment density is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
P(sample average sediment density is at most 3.00)
Calculation the value from standard normal z table, we have,
0.918 is the probability that the sample average sediment density is at most 3.00
Answer:
Given:
Principal= $5,000
After 3 years, Amount= $7,100
After 8 years, Amount= $10,350
Step-by-step explanation:
Interest after 3 years= $7,100- $5,000
=$2,100
Interest in last 5 years= $10,350- $7,100
=$ 3,250
Difference between first 3 years and last 5 years= $3,250- $2,100
=$1,150
Amount= Principal*
10,350=5000
=
2.07=
=1+
1.095-1=
0.095*100=r
r=9.5%
Average rate=
=$475
