Answer:
Sara expect the better grade for Math class.
Step-by-step explanation:
Consider the provided information.
On the Math exam, the mean was µ = 30 with s = 5, and Sarah had a score of X = 45.
Z score for Math: 
On the Spanish exam, the mean was µ = 60 with s = 8 and Sarah had a score of X = 68.
Z score for Spanish:
On the English exam, the mean was µ = 70 with s = 8 and Sarah had a score of X = 70.
Z score for English:
We can observe that Z score of Math is greater than Spanish and English.
Which means that Sarah did the best in her Math exam.
Hence, Sara expect the better grade for Math class.
Set up a proportion. 4 3/4 cup broth is to 10 servings as x cups broth is to 1 serving soup.
x= amount of broth in one serving
(4 3/4)/10= x/1
cross multiply
(4 3/4)(1)= 10x
convert 4 3/4 to improper fraction
(19/4)(1)= 10x
19/4= 10x
divide both sides by 10
19/4 ÷ 10= x
to divide fractions, multiply by reciprocal of 10
19/4 * 1/10= x
multiply numerators; multiply denominators
(19*1)/(4*10)= x
19/40 cup= x
ANSWER: 19/40 cup in one serving
Hope this helps! :)

The correct function is h(t)=-16t^2+200t+50.
Hi, to answer this question we simply have to replace t =0 in the function given:
h(t)=-16t^2+200t+50.
h (0) = -16t^2+200t+50.
h(0) = 50
