Answer:
b. Kathy
Step-by-step explanation:
We compare each of their score by how far away from the mean when in term of the standard deviation. Using the following formula

For John he is (85 - 75)/5 = 2.
For Kathy she is (80 - 50)/10 = 3.
Since Kathy is 3 standard deviation better than her class' average, while John is only 2's. We conclude that Kathy did better.

Answer:
infinite solutions
Step-by-step explanation:
-3f + 3f = 0
0=0
This is always true so there are infinite solutions
A= 4 tenth 2 hundredth 3 thousandth
b= 3 tenth 2 hundredth 6 thousandth 7 ten thousandth 8 hundred thousandth
c= 4 tenth 5 hundredth 2 thousandth 4 ten thousandth
d= 3 tenth 0 hundredth 0 thousandth 6 ten thousandth
Answer:100 ml/hr
Step-by-step explanation:
client has orders to receive 2 liters of IV fluid over a 24-hour period
½ this amount to be infused in the first 10 hours of treatment = ½ ×2 lires
= 1 litre =1× 000 ml= 1000ml
If 1000 ml is received in 10hrs
x ml will be received in 1 hrs
x = 1× 1000/10
= 100ml per hr
