BA = Number of hits / Times at bat

BA = 280 / 300

BA = 0.933

No one past or present, has ever had that kind of batting average.

Ty Cobb has a lifetime average of 0.366

Ted Williams was the last play to average 0.406 in a season. (Over 400). He did it in 1941.

Answer:

C

Step-by-step explanation:

So if we look at the information that we already know, Layla's reading to months ratio is, 6:2. But to find out the equation we want to find out how many books she reads in ONE month instead of two.

Divide 2/2, and for ratios if you divide one side you have to do the same thing to the other side, so we get, 3:1. Where Layla reads 3 books per 1 month.

Therefore the answer is C.

If we wanted to double check our answer we could substitute our information back in:

6=3×2

6=6

Since the equations equal each other, we know we got it correct.

Direct proportion: If a variable increases then other variable also increases with a constant factor  i.e.  y = kx

Inverse proportion:  if a variable increases then other variable decreases with a  constant factor  i.e   xy = k

Assume that food will last for d days if 20 more persons join the camp.

Understand the fact that for given food number of days food last is inversely proportional to the number of persons hence product of days food lasts and number of persons is constant,

Days x number of persons = constant

Equate the product of 300 persons and 42 days  with (300 + 20) person and d days to solve for d.

[tex](300+20) *d=300*42[/tex]

⇒ [tex]d = \frac{12600}{320}[/tex]

⇒ [tex]d =\frac{1260}{32}[/tex]

⇒ [tex]d=\frac{315}{8}[/tex]

⇒ [tex]d=39.375[/tex] [tex]days[/tex] [tex]or[/tex] [tex]39(\frac{3}{8} )days[/tex] [tex]in[/tex] [tex]fraction[/tex]

Hence, if 20 more people Join (320 people ) it will last 39.375 days in decimal or 39 3/8 days in fraction

17 is what percent of 68?

Its 25%

17/68*100

= (17*100)/68

= 1700/68 = 25

Answer:

25%

Step-by-step explanation:

Question : 17 is what percent of 68?​

Answer :

To solve this let the unknown percentage be x .

Let us solve now.

68 × x% = 17

68 × [tex]\frac{x}{100}[/tex] = 17

And now let us find the percentage by making x as the subject.

[tex]x=\frac{17*100}{68}[/tex]

[tex]x = \frac{1700}{68}[/tex]

[tex]x =25[/tex]

Therefore, the percentage is 25%

Answer:   3 mol of O₂

Solution:

The Balance chemical equation is as follow,

                               2 KClO₃    →    2 KCl  +  3 O₂

According to this equation on decomposition 2 moles of Potassium chlorate (KClO₃) produces 2 moles of Poatassium chloride (KCl) and 3 moles of oxygen gas (O₂).

Therefore, when,

                    2 moles of KClO₃ produces  =  3 moles of O₂

So,

                 2 moles of KClO₃ will produce  =  X moles of O₂

Solving for X,

                    X =  (2 mol × 3 mol) ÷ 2 mol

                   X  =  3 mol of O₂

Using above method you can calculate any amount of O₂ or KCl produced by decomposing any amount of KClO₃.

Answer:

3 mol of O₂

Answer:

n2=v2n1/v1

Or B

Step-by-step explanation:

P, R, and T are constant, then the volume is directly proportional to the mole. Then the correct option is A.

An ideal gas is a theoretical composed of a set of randomly moving gas particles that interacts only through elastic collision.

Given

A balloon containing 0.040 mol of a gas with a volume of 5.0 mL was expanded to 1.0 L.

[tex] \rm V_1 = 5 \ mL\\ V_2 = 1000 \ mL\\ n_1 = 0.040 \ mol [/tex]

We know the equation of the ideal gas.

[tex] \rm PV = nRT [/tex]

where P, R, and T are the constant, then

[tex] P \propto n[/tex]

Then we have

[tex] \rm \dfrac{V_2}{V_1} = \dfrac{n_2}{n_1} \\\\ V_2 = n_2 *\dfrac{V_1}{n_1} [/tex]

Thus, the correct option is A.

Answer:

When x=0 the friend is 200 miles from the restaurant and at x=5 the friend reaches the restaurant. When x=0 you are 100 miles from the restaurant, so 100 is the y intercept, and when x=5 you reach the restaurant so 5 is the x intercept. We have y=mx+100 and y=0 when x=5, so 0=5m+100 therefore m=-20 and the equation is y=-20x+100.

Answer:

D) [tex]f(x)=8x^5+7x^3-5x[/tex]

Step-by-step explanation:

A function is odd if its graph is symmetric to the origin, which we can check this if [tex]f(-x)=-f(x)[/tex] is true:

Option A

[tex]f(x)=7x^4+13x^3-11\\\\f(-x)=7(-x)^4+13(-x)^3-11\\\\f(-x)=7x^4-13x^3-11[/tex]

Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry

Option B

[tex]f(x)=5x^7+4x^6+3x^5+x\\\\f(-x)=5(-x)^7+4(-x)^6+3(-x)^5+x\\\\f(-x)=-5x^7+4x^6-3x^5+x[/tex]

Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry

Option C

[tex]f(x)=13x^5-\frac{1}{2}x^3+7x+3\\\\f(-x)=13(-x)^5-\frac{1}{2}(-x)^4+7(-x)+3\\ \\f(-x)=-13x^5-\frac{1}{2}x^4-7x+3[/tex]

Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry

Option D

[tex]f(x)=8x^5+7x^3-5x\\\\f(-x)=8(-x)^5+7(-x)^3-5(-x)\\\\f(-x)=-8x^5-7x^3+5x[/tex]

Since [tex]f(-x)=-f(x)[/tex], then the function DOES have odd symmetry. You can also see that the function is odd because every term has an odd exponent.
