Answer:
4 hours
Step-by-step explanation:
if you have $350
you'd subtract 50 por que it's a one time fee.
which leaves with 300
then you'd divide 75 into 300
to see how many hours you'd receive with the remaining of your $300.
which is four.
Answer:
19,23
Step-by-step explanation:
9+x-7≥ 21
Combine like terms
2+x≥21
Subtract 2 from each side
2+x-2 ≥21-2
x≥19
Any number greater than or equal to 19
Answer:
m = —1/3
Step-by-step explanation:
There are two clear points shown on the graph
point 1: (0;3)
point 2: (6;1)
![m = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
![m = \frac{1 - 3}{6 - 0}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B1%20-%203%7D%7B6%20-%200%7D%20)
![m = - \frac{2}{6}](https://tex.z-dn.net/?f=m%20%3D%20%20-%20%5Cfrac%7B2%7D%7B6%7D%20)
![m = - \frac{1}{3}](https://tex.z-dn.net/?f=m%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B3%7D%20)
Answer:
a) 95% confidence interval estimate of the true weight is (3.026, 3.274)
b) 99% confidence interval estimate of the true weight is (2.944, 3.356)
Step-by-step explanation:
Confidence Interval can be calculated using M±ME where
- M is the mean of five successive weightings (3.150)
- ME is the margin of error from the mean
And margin of error (ME) can be calculated using the formula
ME=
where
- t is the corresponding statistic in the given confidence level and degrees of freedom(t-score)
- s is the standard deviation of the random error (0.1)
Using the numbers 95% confidence interval estimate of the true weight is:
3.150±
≈3.150±0.124
And 99% confidence interval estimate of the true weight is:
3.150±
≈3.150±0.206
J
![\alpha gv](https://tex.z-dn.net/?f=%20%5Calpha%20gv)
j=agv where a is a constant of proportionality.
j=1 when g=4 and v=5
1=a*4*5
1=20a
a=1/20
a= 0.05
j=0.05gv
When g=10 and v=9,
j=0.05*10*9
j=0.5*9
j=4.5
