there is a jar containing 27 black and 33 gold jelly beans. you will get a chance to draw 10 jelly beans at random from the jar. on each draw, 0.5 is the probability of drawing a gold jelly bean

How can I find the probability?

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.

there is a jar containing 27 black

and 33 gold jelly beans.

you will get a chance to draw 10 jellybeans at random from the jar.

on each draw, what is probability of drawing a gold jelly bean

Add up the total number of jellybeans, 27 + 33 = 60

Divide the number of gold jellybeans by the total: 33/60 and reduce the fraction to 11/20

=0.55

Hence, there is a jar containing 27 black and 33 gold jelly beans. you will get a chance to draw 10 jelly beans at random from the jar. on each draw, 0.5 is the probability of drawing a gold jelly bean

The given exponential function represents the growth in function with a percentage increase as 57.3%.

Given we have the exponential function as :

y=8800(1.573)ˣ

it is in the form of: y=k.aˣ

therefore, if a>2 then the function represents growth.

and if a<1 then the function represents decay.

now, x=1.573

1.573 > 1

so, the function represents change in growth.

therefore, 1.573 - 1

= 0.573

= 57.3%

hence the change in growth of the function is increased by 57.3%.

Answer:

x ≈ 15

Step-by-step explanation:

using Pythagoras' identity in the right triangle

a² + b² = c²

with a = 8, b = x , c = 17

8² + x² = 17²

64 + x²  = 289 ( subtract 64 from both sides )

x² = 225 ( take square root of both sides )

The quotient of a-3/7 / 3-1/21 is 3/2(a - 3)

The quotient of a-3/7 / 3-a/21 is -3

From the question, we are to determine the quotient of the given division operation.

The given division operation is

a - 3/ 7 / 3 -1 / 21

That is,

a - 3/ 7 ÷ 3 -1 / 21

This becomes

a - 3 / 7 × 21 / 3 -1

a - 3 / 7 × 21 / 2

3(a - 3) / 2

= 3/2(a - 3)

If we are to find the quotient of

a - 3/ 7 / 3 -a / 21

This becomes

a - 3/ 7 ÷ 3 - a / 21

a - 3/ 7 × 21 / 3 - a

21(a -3) / 7(3 - a)

3( a - 3) / (3 -a )

Multiply the numerator and the denominator by -1

-1 × 3( a - 3) / -1 × (3 -a )

-3( a - 3) / (-3 + a)

-3( a - 3) / (a - 3)

= -3

Algebra is one of the areas of mathematics where mathematical expressions can be used to represent situations or problems. In order for a mathematical statement to make sense, it must have mathematical operations like addition, subtraction, multiplication, and division as well as variables like x, y, and z. Every branch of mathematics, including calculus, trigonometry, and coordinate geometry, uses algebra. The equation 2x + 4 = 8 is a simple algebraic formula.Mathematical branch known as algebra deals with symbols and arithmetic operations on them. These symbols are referred to be variables since they lack set values. We frequently observe specific values that change in our day-to-day situations. However, there is a continuing need to depict these shifting values. These values are frequently represented in algebra by symbols, which are known as variables, such as x, y, z, p, or q. In order to determine the values, additional arithmetic operations such as addition, subtraction, multiplication, and division are performed on these symbols.

From the information, Foster is centering a photo that is 7 1/5 inches wide on a scrapbook page that is 16 inches wide.

It should be noted that 7 1/2 is the same as 7.5. Therefore,we can subtract and this will be:

= 16 - 7.5

= 8.5

Since we know that the scrapbook is 8.5 inches wider,we will divide the width by 2 to get the distance of either side and this will be:

The perpendicular distance ( height ) between the parallels sides of the trapezoid is 5cm.

A trapezoid is simply a quadrilateral with at least one pair of parallel sides.

The area of trapezoid is expressed as;

A = h × (a + b)/2

Where a is base a, b is base b and h is height.

Given the data in the question;

To determine the height of the trapezoid, plug the given values into the above formula and solve for h.

A = h × (a + b)/2

31.5cm² = h × ( 7.3cm + 5.3cm)/2

31.5cm² = h × ( 12.6cm )/2

31.5cm² = h × 6.3 cm

h = 31.5cm² / 6.3 cm

Height h = 5cm

Therefore, the height of the given trapezoid is 5 centimeters.

Step-by-step explanation:

8(x+3)^2/2(x+3)

[8(x + 3)(x + 3)]/2(x + 3)

8 ÷ 2 = 4

(x + 3)(x + 3) ÷ (x + 3) = (x + 3). In other words, we cancel one of the numerator factors.

Answer: 4(x + 3).

Answer:

4(x + 3)

or 4x + 12.

Step-by-step explanation:

8(x + 3)^2/ 2(x + 3)

x + 3 is common to both numerator and denominator of the fraction so they simplify to (x + 3)^2 / (x + 3) = (x+3).

the answer is 8 * (x + 3) / 2

= 4(x+ 3).

The solution to the given inequalities is -7 < x ≤ 6. The graph of the inequality is shown below on a number line.

From the question, we are to solve the given inequalities

The given inequalities are

-3x - 7 < 14 and -25 ≤ -3x - 7

Solving -3x - 7 < 14

-3x - 7 < 14

Add 3x to both sides of the inequality

-3x + 3x - 7 < 14 + 3x

-7 < 14 + 3x

Subtract 14 from both sides

-7 - 14 < 14 - 14 + 3x

-21 < 3x

Divide through by 3

-21/3 < 3x/3

-7 < x

Solving -25 ≤ -3x - 7

-25 ≤ -3x - 7

Add 3x to both sides

-25 + 3x ≤ -3x + 3x - 7

-25 + 3x ≤ - 7

Add 25 to both sides

-25 + 25 + 3x ≤ - 7 + 25

3x ≤ 18

Divide through by 3

3x/3 ≤ 18/3

x ≤ 6

As for the "Select the equation that represents the given situation" I don't know what this really means so I didn't do that. Sorry.

The horizontal asymptote of the function is y=36 and vertical asymptote is x = 6 and its end behavior is f(x)→6.

As the independent variable approaches a certain value, the function approaches asymptotes, but does not cross them. They could be angled, vertical, or horizontal.

ascending asymptotes

There will be a vertical asymptote at x=a if the denominator factor of a rational function, (x - a), is not matched by the same factor in the numerator.

horizontal asymptotes:

When x is large, the value of a rational function approaches the ratio of the highest-degree terms in the numerator and denominator.

Given the function is f(x) = 6x/x-36

limx→±∞ 6x/x-36

= limx→±∞ 6/1-36/x

= 6 ⇒ horizontal asymptote: y = 6

Consider denominator = 0 ↔ x-36 = 0 ↔ x=36

limx→₊₂₅ 6x/x-36

= 6×36/0⁺ = ∞ ⇒ vertical asymptote: x = 36

End behavior of f(x):

As x → -∞ or x → ∞, f(x) → 6.

Hence we get the asymptote and the end behavior of the function.

The probability of someone being 5 feet and 4.2 inched tall is 0.2877

Probability:

Probability means the possibility of occurring the specific even across the total number of event.

Given,

100 people where sampled and their heights were recorded, it was discovered the mean height was 5 feet and 6.3 inches with a standard deviation of 3.75 inches.

Here we need to find the the probability of someone being 5 feet and 4.2 inches tall.

From the given details, we know that,

n = 100

mean (ч) = 5 feet and 6.3 inches

standard deviation (σ) = 3.75 inches

We know that the formula to find the probability is,

P = (x - ч)/σ

But here we have used the different measurement for each. So, the first step is convert them into inches.

So,

5 feet and 6.3 inches = 60 + 6.3 inches = 66.3 inches.

Similarly 5 feet and 4.2 inches = 64.2 inches.

So, the probability is,

P (X < 64.2) = (64.2 - 66.3)/3.75

P (X < 64.2) = -0.56

Based on the standard normal table to conclude that:

P (X < 64.2) = -0.56 = 0.2877

Therefore, the probability of someone being 5 feet and 4.2 inches tall is 0.2877.
