Answer:
800 milliliters
Step-by-step explanation:
we know that
To find out the total amount Kelly drank, add the amount of coffee and the amount of yogurt and convert the result to milliliters.
so
0.5+0.3=0.8 liters
Remember that
1 liter= 1,000 milliliters
so
0.8 liters=0.8*1,000=800 milliliters
Answer:
113
Step-by-step explanation: 113 is the prime number in between those numbers, thats the only one
True the shading is called an solution set
Answer:
A sample size of 385 is needed.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
That is z with a pvalue of 
, so Z = 1.96.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
You feel that a reasonable estimate of the standard deviation is 10.0 hours.
This means that 
What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence?
A sample size of n is needed. n is found when M = 1. So
Rounding up:
A sample size of 385 is needed.
Answer:
X = 6
Step-by-step explanation:
DU = DU .....(1)
DV =DW ......(2)
angle VDU = angle WDU .......(3)
so triangle VDU and triangle WDU are Congruent Triangles
thus VU = WU
we solve : 9x + 1 = 7x + 13 , x = 6
