Answer:

First player

Range = 0.081

Mean = 0.283

Second player

range = 0.174

mean = 0.284

Step-by-step explanation:

Mathematically, range is highest value - lowest value while mean refers to the average ( sum of values/count of values)

For first player

Range = (0.319 - 0.238) = 0.081

Mean = (0.238 + 0.289 + 0.263 + 0.302 + 0.285 + 0.319)/6 = 0.283

For the second player;

Range = 0.348 - 0.174 = 0.174

mean = (0.259 + 0.348 + 0.334 + 0.278 + 0.311 + 0.174)/6 = 1.704/6 = 0.284

i  had this question before lol

Answer:

m∠C = 56 and (4x + 16) = 180

Step-by-step explanation:

The sum of angle in a triangle is 180, hence:

<A+<B+<C = 180

Given

<A = 2x+1

<B = x

<C = x+15

Substitute

2x+1+x+x+15 = 180

collect like terms:

2x+x+x+1+15 = 180

4x+16 = 180

4x = 180-16

4x = 164

Divide both sides by 4

4x/4 = 164/4

x = 41°

Since <A = 2x+1

<A = 2(41)+1

<A = 82+1

<A = 83

<B = x = 41

<C = x+15

<C = 41+15

<C = 56

Based on the calculation above, the true statements are:

m∠C = 56 and (4x + 16) = 180

Answer:

Step-by-step explanation:

Lenght should be the greater here. I am considering your question however.

Let length side is 'x'.

The width side is 'x +13'

Perimeter of a rectangle : 2 ×( length + width)

given that perimeter is 82

2 × ( x + x + 13) = 82

2 × ( 2x + 13) =82

4x + 26 = 82

2x = 56

x = 28 cm

length is 28

width is 41

Answer:the answer is 9998.

Step-by-step explanation:

The largest 4 digit number divisible by 2 . The number should be divisible by 2 or multiple of it. So the largest 4 digit number is 9999 it is not divisible by 2 so the earlier number 9998 can be considered so as it is divisible by 2. It is the answer is 9998.

Answer:

you plug those numbers into the equation

Step-by-step explanation:

f(x) = -5x + 17

f(10) = -5(10) + 17 = -50 + 17 = - 33

Answer: C

Step-by-step explanation:

Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -

2x - 3x + 6 = 8

An expression in mathematics defines a relationship between one variable (the independent variable, x)  and another variable (the dependent variable, y). For example -

f(x) = 4x + 6

Given is the equation equating two functions as -

2x + 6 = 3x - 8

We have -

2x + 6 = 3x - 8

2x - 3x + 6 = 8

-x + 6 = 8

Therefore, Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -

2x - 3x + 6 = 8

Answer:

i really have no clue what ur asking so i will solve this the way i know how to

Step-by-step explanation:

4x^2+12x+5

Answer:

I had no idea what u were asking but i solved for r and got r>45

Answer:

r > 45

Step-by-step explanation:

6 <-3 + r/5

add 3 left and right of the < sign gives:

6 +3 <-3 +3 + r/5

9 < 0 + r/5

9 < r/5

multiply left and right of the < sign gives by 5 gives:

9 * 5 < 5* r/5

45 < r

r > 45

Answer:

z = 40° (V. O. A)

Now find x

40 + 25 + x = 180(A. S. P)

65 + x = 180

x = 180 - 65

x = 115°

Now find y

x = y (V. O. A)

Y = 115°

So angles are

X = 115°

Y = 115°

Z = 40°

Answer:

932/1000

Step-by-step explanation:

To write .932 as a fraction you have to write .932 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

.932 = .932/1 = 9.32/10 = 93.2/100 = 932/1000

And finally we have:

.932 as a fraction equals 932/1000

Answer:

hundredths

Step-by-step explanation:

Answer:

11a + 2 = 9a + 4 ( Subtract 9a from both sides)

11a - 9a + 2 = 9a - 9a + 4

2a + 2 = 4 (Subtract 2 from both sides)

2a + 2 - 2 = 4 - 2

2a = 2 (Divide both sides by 2)

2a/2 = 2/2

a = 1

Step-by-step explanation:

Simplify any fractions.

11a + 2 = 9a + 4

2a + 2= 4

We simplify as shown below

11a + 2 = 9a + 4 ( Subtract 9a from both sides)

11a - 9a + 2 = 9a - 9a + 4

2a + 2 = 4 (Subtract 2 from both sides)

2a + 2 - 2 = 4 - 2

2a = 2 (Divide both sides by 2)

2a/2 = 2/2

a = 1

Answer:

The aspect ratios of both are not same

Step-by-step explanation:

Here, we want to check if the given ratios are equivalent.

So what we want to do here is to check if 16/9 is equivalent to 2.35:1

Mathematically; 16/9 is same as 1.78/1

We can see that 1.78/1 is not same as 2.35/1

Hence, the aspect ratios of both are not the same thing

Answer:

The answer is below

Step-by-step explanation:

A linear equation is represented by the equation y = mx + b, where m is the rate of change, b is the value of y at x = 0, y is a dependent variable and x is an independent variable.

Let t represent the number of years since 1992, and P represent the per capita consumption of fish and shellfish in the U.S.

In 1992 (t = 0), the per capita  consumption was 14.7 pounds, this can be represented by (0, 14.7) while in 1994 (t = 1994-1992=2) it was 15.1 pounds this can be represented by (2, 15.1)

Using (0, 14.7) and (2, 15.1) we can get the equation of the line using:

[tex]P-P_1=\frac{P_2-P_1}{t_2-t_1}(t-t_1)\\ \\P-14.7=\frac{15.1-14-7}{2-0}(t-0)\\ \\P-14.7=0.2t\\\\P=0.2t+14.7[/tex]

In the year 2002 (t = 2002-1992 = 10), the per capita consumption of fish and shellfish is:

P = 0.2(10) + 14.7

P = 16.7 pounds
