He must anticipate drawing a red tile. 30 times minimum.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given this, Alex placed 8 blue tiles and 12 red tiles in a container. He plans to draw a tile, record its color, and replace it in the container before drawing another.

Let X be the number of times a red tile is drawn from the container

Number of red tiles = 12

Total tiles = 12 + 8 = 20

p = P(randomly drawing a red tile) = 12/20 = 0.6

n = 50 number of draws or trials

Since Alex replaces the tile before he draws the next tile, we can model

the distribution of X according to Binomial Distribution

Thus, X ~ Binomial with n = 50 and p = 0.6

The Expected value of a binomial variable is E(X) = np

E(X) = n * p

= 50 * 0.6

= 30

therefore,  he should expect to draw a red tile At least 30 times.

Step-by-step explanation:

The table format is all messed up but I was able to figure out the numbers.

Since 10 books cost $122.50, each book must cost $122.50/10 = $12.25

For 1 book => 10 x $12.25 = $122.50

For 11 books => 11 x $12.25 = $134.75

If f′ is growing, the f graph is concave up on the interval. In the event that f′ is decreasing, the f graph is concave down on the interval. This has been obtained by using the concept of derivatives.

What are derivatives?

In mathematics, a quantity's instantaneous rate of change with respect to another is referred to as its derivative. Investigating the fluctuating nature of an amount is beneficial.

Assume that f is differentiable on interval I.

If f′ is increasing, the f graph is concave up on I. In the event that f′ is decreasing, the f graph is concave downward on I. The graph of f is considered to have no concavity if f′ is constant.

Hence, concave up is when f' is increasing and when it is decreasing, it is concave down.

Answer:

Step-by-step explanation:

You want the expressions in the correct sequence to prove ...

  z + z + z + z = 4z

The multiplicative identity property tells you z × 1 = z. Anything multiplied by 1 is unchanged. This lets us replace z in the original expression by z·1 in every case.

The distributive property tells you that multiplication distributes over addition. This means ...

  z ·1 + z · 1 + z · 1 + z · 1 = z · (1 + 1 + 1 + 1)

The properties of addition and the set of integers tell us that ...

  1 + 1 + 1 + 1 = 4

so we can replace the indicated sum by its value:

  z · (1 + 1 + 1 + 1) = z · 4

The commutative property of multiplication says a product is the same if the operands are in a different order:

  z · 4 = 4·z = 4z

This is the last step in showing z + z + z + z = 4z.

Step-by-step explanation:

She used 7.90 paint with white paint on her bedroom walls.

To solve such problems we must know about fractions and subtraction.

Fraction

A fraction is a way to describe a part of a whole, the amount of white paint Jane used is 7.4 pints.

Given to us,

Total paint used my Jane = 8.3 pints = 83/10 pints,

the amount of blue paint = 2/5 pints,

Amount of white paint

amount of white paint = Total paint used - the amount of blue paint

=83/10-2/5

=83/10-2*2/5*2

=83/10-4/10

=79/10

=7.9pints

Hence, the amount of white paint Jane used is 7.9pints.

The unsigned binary equivalent of the following unsigned decimal integer value 12 is 1100

An integer is a whole number that can be positive, negative, or zero. An unsigned integer is a non-negative integer that only represents positive values or zero.

To convert an unsigned decimal integer to its equivalent binary representation, you'll need to understand the basic concepts of binary and the process of converting decimal to binary.

Here we have to consider the unsigned decimal integer value 12.

To convert it to binary, start by determining the largest power of 2 that is less than or equal to 12, which is

=>  2³ = 8.

Write a 1 in the binary place corresponding to 2³ and subtract 8 from 12 to get 4.

=> 12 - 8 = 4

Then, determine the largest power of 2 that is less than or equal to 4, which is

=> 2² = 4.

Write a 1 in the binary place corresponding to 2² and subtract 4 from 4 to get 0.

=> 4 - 4 = 0

The binary equivalent of 12 is 1100.

If (x,y) is a solution to equations y = x²  and  2y+6 = 2(x+3) , then the value of xy is (a) 1  .

The values of x and y are solutions to two equations:

⇒ y = x²   ....equation(1)

⇒ 2y + 6 = 2(x + 3)    ....equation(2)

To find the value of xy, we first need to find the values of x and y which satisfy both equations.

We can put value of y from the equation(1) into the equation(2) :

⇒ 2y + 6 = 2(x + 3)

⇒ 2x² + 6 = 2(x + 3)

⇒ 2x² + 6 = 2x + 6

⇒ 2x² - 2x = 0

⇒ 2x(x - 1) = 0

that means either "2x=0"   or "x-1=0" ;

⇒   x = 0  or x = 1 .

when x = 1  , we have y = (1)² = 1 .

So , the product is = 1 × 1 = 1 .

Therefore , the value of xy is (a) 1  .

Average rate of change for the given function is 2.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given that the graph is a line. So the function is linear.

Average rate of change of a linear function is equal to the slope of the given function, and it will be a constant at any two points on the line.

We have two points from the line (-2, -3) and (1, 3).

Slope of a line with two points (x, y) and (x', y') is,

slope = (y' - y) / (x' - x)

Slope of the given function with two points (-2, -3) and (1, 3) is,

Slope = (3 - -3) / (1 - -2) = 6/3 = 2

Average rate is same value from x = 1 to x = 2.

Let the total number of hours in a single shift be = A

Now , The total length of equal shifts Skylar worked last week = 3 3/4 shifts

The total length of equal shifts Skylar worked last week = 15 / 4 shifts

The total number of hours Skylar worked in the week = 11 1/4 hours

The total number of hours Skylar worked in the week = 45 / 4

Now , the equation will be

Total length of equal shifts Skylar worked last week is equal to total number of hours Skylar worked in the week.

So ,

Total length of one shift of Skylar = total number of hours Skylar worked in the week / Total length of equal shifts Skylar worked last week

On substituting the values in the equation , we get

Total length of one shift of Skylar A = ( 45/4 ) / ( 15/4 )

On simplifying the equation , we get

A = ( 45/4 ) / ( 15/4 )

A = 45 / 15
