Baseball pitchers ages 9 to 14 were followed for 10 years. Four out of 26 who had pitched at least 100 innings in one year had elbow surgery, shoulder surgery or retirement due to a throwing injury. Of 128 who had not pitched this much 6 had such problems (based on data). a. Compute the percentage of each group who have such problems. Compute the difference of the percentages. What is the name for this difference? Write an explanation, for parents of young pitchers, that explains its meaning

b. Compute the ratio of the percentages of each group who have such problems. What is the name for this difference. Then write an explanation, for parents of young pitchers, that explains its meaning.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
