Answer:
Step-by-step explanation:
Sample size = 95
X=cash carried by the persons
x bar = 8.00
s = sample std dev = 2.50
Std error = 
Hence Z score would be
-0.00
b) 
c) 95% conf interval margin of error = ±
=±0.54782
Confi interval = (8-0.5027, 8+0.5027)
= (7.4923, 8.5027)
C)If conf level increases, then width of interval would increase since critical value would increase.
If sample size increases std error would decrease and hence margin of error.
So interval would decrease.
Jenny traveled 70 km/h over 2 hours and 63 km/h over 5 hours. Her travel time was a total of 7 hours.
We need to find out how far she traveled during this 7-hour period.
70 km/h * 2 h = 140 km
63 km/h * 5 h = 315 km
Then, we can add 140 km and 315 km to get a total distance traveled of <em>455 km/h.</em>
We were asked to find the average <em>speed.</em> We can find it now, since we have total distance traveled (455 km) and total time taken (7 hours).
Then,
455km / 7h = 65 km/h.
Step-by-step explanation:
The Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Willa did the reciprocal.
if it's a multiple chose then the answer is b

Capucine played a game where she earned 179 points from building 11 museums and 4 libraries.
Lets assume x points she earn per library
She earns 4 more points for museum than library.
4 more points per museum per x . so the points earned per museum is x+4
she earned 179 points from 11 museums and 4 libraries.
So the equation becomes
( subtract 44 from both sides)
(divide by 15 from both sides)
x = 9
She earns 9 points per library
We know points per museum = x+4 = 9+4 = 13
She earns 13 points per museum .
Answer:
Step-by-step explanation:
The following are the given information:
- The handicapped spot, which is
feet wide and next to the curb. - The other three spots are
feet wide. - There are 4 dividing lines between the spots, and each measures
foot.
The Median D therefore will be a sum of the following:
- The width of the Handicapped Spot
- 3 X The width of the other spots
- 4 X The width of the dividing line
