The probability of the number of students to be selected randomly short or very short is 0.5048 or 50.48% = 50.5%.A is correct option

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Number of students who are.

very short: 45,

short: 60,

tall: 82,

very tall: 21

The total number of students will be

Total sample = 45 + 60 + 82 + 21 = 208

The probability that a randomly selected student will be short or very short will be

Favorable sample = 45 + 60 = 105

Then the probability will be

P=105÷208

P=0.5048=50.48%

p=50.5%

option A is correct choice

Answer:

Step-by-step explanation:

Volume = Bh

Turn the shape so the trapezoid is on the bottom/base

h=18   for overall shape

B = area of base, trapezoid

B = 1/2 (b₁ + b₂) h  

b₁ = 11

b₂ = 25

h = 24   for trapezoid

B = 1/2 (11 + 25)(24)

B = 432

V = Bh

V = (432)(18)

V= 7776 in³

Answer:

c) y = - 2 x +3

d)  y = 1/2  x + 1

Step-by-step explanation:

For c) Look for the exression that contains "3" as the y-intercept (the "b" in the form y = m x + b)

The only equation is y = - 2 x +3

For d) try in all equations if replacing x with 2, gives you an answer "2" for y as well.

The only equation that does such is   y = 1/2  x + 1

Answer:103.25 = 5.5h + 48.25; 10 hours (4th option)

Step-by-step explanation: we know that....h is for the hrs and 5.50 is how much he gets in those hrs .

h=5.50

we also now know he earns 48.25 in tips (that is just tips we dont know how many hrs he worked and made we just know the tips ) so now have a equation .

103.25 (the total all together)

48.25(his tips)

5.50h(how much he gets payed for working in the hrs )

103.25=5.5h+48.25;10 hrs

and we know that is the answer when we solve it and put it in a graphing calculator ....

Answer:

6561

Step-by-step explanation:

So, lets just go over what we know:

The exponent is 4, meaning the number will be multiplyied by itself 4 times.

The number is -9, so we are going to multiply it by -9, 4 times.

We can think of it like this:

9*9*9*9

I used postive nines instead of negative nine since the sign will be postive.(Because its a even exponent)

Now lets solve:

9*9*9*9

=

81*9*9

=

729*9

=

6561

So this is the answer!

Hope it helps! :)

The simplified form of the expression 29 - ( 11 - 2³ ) + 6² ÷ 4 is 35

Given the expression in the question;

29 - ( 11 - 2³ ) + 6² ÷ 4

To simply, replace 2 raised to the power of 3 with 8 and 6 raised to the power of 2 by 36

29 - ( 11 - 2³ ) + 6² ÷ 4

29 - ( 11 - 8 ) + 36 ÷ 4

Now, remove the parenthesis by performing the operation inside the parenthesis.

29 - ( 11 - 8 ) + 36 ÷ 4

29 - 3 + 36 ÷ 4

Now, divide 36 by 4

29 - 3 + 36 ÷ 4

29 - 3 + 9

Next, add -3 and 9

29 + 6

Add 29 and 6

35

Therefore, 35 is the simplified form of the expression.

For figure {0}, the number of tiles will be equal to 2.

Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function

Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Equation : A mathematical equation is used to equate two expressions.

Given is a graph as shown in the image.

The line passes through point -

(3, 8) and (4, 10)

So, the slope of the line will be -

m = (10 - 8)/(4 - 3)

m = 2

y = 2x + c

For the point (3, 8), we can write -

8 = 6 + c

c = 2

For figure {0}, the number of tiles will be equal to 2.

Therefore, for figure {0}, the number of tiles will be equal to 2.

Answer : The answer is option c evaporation

The process in the water cycle that is not driven by the force of gravity is evaporation.

           The water cycle is a series of processes that transport water between the earth's water bodies to the atmosphere, and land, including precipitation in the form of rain as well as snow, evaporation, and transpiration to restore water to the atmosphere.

           The force of gravity is a universal force of attraction that acts on any matter coming towards the earth's surface.

           From the given options, the only option that is not driven by the force of gravity is evaporation.

           This is because water substances evaporate upward and not downward the earth's surface.

The field lines go out of Earth near Antarctica, enter Earth in northern Canada, and are not aligned with the geographic poles.

The total materials handling cost allocated to the modular homes is $246,372.84.

The total materials handling cost allocated to the Prefab Barns is closest to $108,000.

To allocate materials handling cost based on material moves, we must determine proportion of material moves for each product and then apply that proportion to the total materials handling cost.

Proportion of material moves for Modular Homes:

= (Total expected material moves for Modular Homes) / (Total expected material moves for both products)

= 590 / (590 + 190)

= 0.756

Total materials handling cost allocated to Modular Homes:

= Proportion of material moves for Modular Homes * Total materials handling cost

= 0.756 * $325,890

= 246 372.84

= $246,372.84.

To allocate the materials handling cost based on direct labor-hours, we need to determine proportion of direct labor-hours for each product.

For Modular Homes:

Total direct labor-hours for Modular Homes:

= 6,000 units * 800 hours/unit

= 4,800,000 hours

For Prefab Barns:

Total direct labor-hours for Prefab Barns:

= 9,000 units * 300 hours/unit

= 2,700,000 hours

Total direct labor-hours for both products:

= 4,800,000 hours + 2,700,000 hours

= 7,500,000 hours

Proportion of direct labor-hours for Prefab Barns:

= 2,700,000 hours / 7,500,000 hours

= 0.36

Allocated materials handling cost for Prefab Barns:

= Proportion of direct labor-hours for Prefab Barns * Total materials handling cost

= 0.36 * $300,000

= $108,000.
