Answer:
44
Step-by-step explanation:
if she had 10 left at the end and you add the other half from lunch which is 12, then that gives you 22. Since before lunch she had half (22), all you gotta do is add the other half which is 22. 22+22=44 and that's your answer.

Answer:
$0.80
Step-by-step explanation:
If the 100 pounds was bought separately (of course in real life you will probably not)
= 100 pounds x $0.0825/pound
= $8.25
As you can see it will cost more than if you buy a 100 pound sack.
Cost Difference = $8.25 - $7.45 = $0.80
That means you will save $0.80 from it.
Answer: 5.000
Step-by-step explanation:
The formula to find the standard deviation for binomial distribution is given by :-
, where p is the probability of getting success in each trial and n is the number of trials.
Given : The probability of flipping a coin and noting Heads is = 0.50
The total number of trials = 100
Then , the standard deviation of Heads to be noted will be :-

Hence, the standard deviation of Heads to be noted = 5.000
Answer:

Step-by-step explanation:
We have been given that a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is 50 centimeters tall.
First of all we will find slope of our line using given points.

Upon substituting coordinates of our given points in slope formula we will get,


Therefore, slope of our given line is 2.
Since the equation of a line in point slope form is
.
Upon substituting m=2 and coordinates of one point in above equation we will get,

Therefore, the equation that models the height of the plant (y) after x days will be
.
