Step-by-step explanation:

Answer: statistic.

Step-by-step explanation:

A parameter is a measure of characteristic in a population.

A statistic is a measure of characteristic in a sample.

Given: A survey of 32 out of 50 in a basketball game showed 20.5% enjoyed the game.

Since group of 32 games out of 50 is representing a sample here.

So, 20.5% is the measure of sample, i.e. it is a statistic.

Scale factor for the dimensions of the gymnasium on the blue print will be represented by the expression,

Scale factor = [tex]\frac{\text{Dimension of the blueprint}}{\text{Dimension of the original}}[/tex]

Length of the gymnasium = [tex]96[/tex] feet

Length of the gymnasium on the blueprint = [tex]5.5[/tex] inches

Therefore, scale factor for the blueprint = [tex]\frac{5.5}{96}[/tex]

                                                                  = [tex]0.0573[/tex]

If the width of the gymnasium = [tex]75[/tex] feet

For the width on the blueprint,

[tex]0.0573=\frac{\text{Width on the blueprint}}{75}[/tex]

Width on the blueprint = [tex]4.29[/tex]

                                      ≈ [tex]4.3[/tex] inches

Therefore, width of the gymnasium on the blueprint will be [tex]4.3[/tex] inches.

Answer:

The puck traveled 53.8 meters.

Step-by-step explanation:

Currently, the player is 55 meters away from the opponent's goal.

After the shot, the puck is 120 centimeters = 1.2 meters from the opponents goal.

So, this means that the puck traveled 55 - 1.2 = 53.8 meters.

Answer:

26

Step-by-step explanation:

You would do 24 × 13/12

This would be 26

Answer:

26

Step-by-step explanation:

First, we convert the question into an equation.

12/13x = 24.

We multiply both sides by 13 to get rid of the fraction that is on the left side of the equation.

12x=312.

Dividing both sides by 12, we get:

x = 26

Answer:

0m

Step-by-step explanation:

Before the ball is thrown, it is at the ground level. At the ground level, the height is zero. Substitute h = 0 into the equation;

h(x)=-x^2+10x-16

0=-x^2+10x-16

x^2-10x+16 = 0

Factorize

x^2-8x-2x+16 = 0

x(x-8) - 2 (x-8) = 0

x-2 = 0 and x - 8 = 0

x = 2 and 8

At x = 2

h(2) = -2^2 + 10(2) - 16

h(2) = -4 + 4

h(2) = 0

Hence the height of the ball at the time it is thrown is 0m

Answer:

Expected value = 1.457

Standard deviation = 0.671

Step-by-step explanation:

Given the data:

Language (X) : 1 ____ 2 ____ 3 ____ 4 ____ 5

P(X) _____0.630 _ 0.295 _0.065_0.008_0.002

Expected value :

ΣX*P(x) = (1*0.630)+(2*0.295)+(3*0.065)+(4*0.008)+(5*0.002)

= 1.457

Standard deviation : sqrt(Var(x))

Var(X) = Σx^2p(x) - E(x)

Var(X) = (1^2*0.630)+(2^2*0.295)+(3^2*0.065)+(4^2*0.008)+(5^2*0.002) - 1.457^2

= 2.573 - 1.457^2

= 0.450151

Standard deviation = sqrt(0.450151) = 0.6709329

= 0.671

Average Expected number of languages known by student, ie Expected Value = 1.457 ; Standard Deviation of Data = 0.45015

A] Expected Value represents the average, calculated by summing products of outcomes & their corresponding probabilities. E (X) = X . P (X) , where X are events & P (X) are corresponding probabilities.

E (X) = 1 (0.63) + 2 (0.295) + 3 (0.065) + 4 (0.008) + 5 (0.002) = 1.457

B] Standard Deviation denotes the measure of dispersion, spread around average. Formula = [tex]X^2 P (X) - [ E (X) ]^2[/tex]

1 (0.63) + [tex]2^2[/tex] (0.295) + [tex]3^2[/tex] (0.02,65) + [tex]4^2[/tex] (0.008) + [tex]5^2[/tex] (0.002) - [tex](1.457)^2[/tex]

= 2.573 - (1.457)^2 = 0.45015

Answer:

i think its 3

Step-by-step explanation:

Answer:

x = 29

Step-by-step explanation:

(2x - 13)° + (7x - 68)° = 180° (linear pair angles add up to 180°)

Solve for x

2x - 13 + 7x - 68 = 180

Add like terms

9x - 81 = 180

Add 81 to both sides

9x = 180 + 81

9x = 261

Divide both sides by 9

x = 261/9

x = 29

Answer:

a.) likely

b.) unlikely

c.) equally

Step-by-step explanation:

A.) ~~~ there are more numbers less than 9 than numbers greater than or equal to 9, so rolling this is likely

B.) ~~~ There are only 4 multiples of 3, so rolling this is unlikely.

C.) ~~~ There are an equal amount of numbers greater than 6 and less than or equal to 6, so the chances of this are 50/50, or equal

Answer:

200,000

Step-by-step explanation:

Step one:

given data

We are given that 15% of a non-profits Donations is about 30,000

Required

The amount in total received in donation

Step two:

Let the total donation be x

so

15/100*x= 30000

solve for x

0.15*x= 30000

divide both sides by 0.15

x= 30000/0.15

x=200,000

Hence the total donation is about 200000

Answer:

He will spend RM 28.44.

Step-by-step explanation:

Each mile has 1.61 km.

So the distance, in miles, is given by:

[tex]\frac{330}{1.61} = 205[/tex]

For 60 miles, he uses 4.5 liters. So, for 205 miles, he will use:

[tex]\frac{205*4.5}{60} = 15.375[/tex]

For the trip, he uses 15.375 liters. Each liter costs RM 1.85. So he will spend:

[tex]15.375*1.85 = 28.44[/tex]

He will spend RM 28.44.

Answer:

1/8 * 3

Step-by-step explanation:

1/8*3 means the numerator gets multiplied by 3 so we get (1*3)/8 which is 3/8

The equivalent value of the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = pq

when the value of p = 3/4

And , when the value of q = 1/2

On simplifying the equation , we get

3/8 = ( 3/4 ) ( 1/2 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 3/4 ) ( 1/2 )

A = ( 3/4 ) ( 1/2 )

A = 3/8

Therefore , the value of A = 3/8 = ( 3/4 ) ( 1/2 )

Hence , the fraction is A = 3/8 = ( 3/4 ) ( 1/2 )
