The probability that two students out of 30 students have their birthday on the Same day is 0.706, that is nearly 71%

The possibility of an event or outcome happening contingent on the occurrence of a prior event or outcome is known as conditional probability.

the likelihood of the preceding event is multiplied by the probability of the subsequent,or conditional, occurrence to determine the conditional probability.

In a year we have 365 days

probability at least 2 people share the same birthday=1 - probability no people share the same birthday

the first student can be born on any day,so we'll give him a probability of 365/365

the probability of the next born is 364/365

the probability of the third born is 336/365

[tex] \frac{365 \: factorial}{335 \: factorial \: . {365}^{30} } [/tex]

this is the simplified form of the 30 probabilities product.= 0.294

therefore

probability at least 2 people share the same birthday=1 - probability no people share the same birthday

1 - 0.294= 0.706

Answer:

Step-by-step explanation:

r2=x2+y2,tanθ=yx,x=rcosθ,y=rsinθ

The value of Lilah's stock after the decrease of 8 % is $ 368

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the initial amount of money Lilah invested in stocks be = A

The value of A is = $ 400

Now , the percentage decrease in the value of stocks = 8 %

So , the equation will be

The value of the stocks after the decrease = initial amount of money Lilah invested in stocks -  ( percentage decrease in the value of stocks x initial amount )

Substituting the values in the equation , we get

The value of the stocks after the decrease = 400 - ( 8/100 ) x 400

The value of the stocks after the decrease = 400 - ( 8 x 4 )

The value of the stocks after the decrease = 400 - 32

The value of the stocks after the decrease = $ 368

Therefore , the value of A is $ 368

Hence , The value of Lilah's stock after the decrease of 8 % is $ 368

The box's volume V expressed as a function of x V(x) =(x+1)(16 -2x) ².

A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle having equal length and width.

An equal-length rectangle with two neighboring sides. a quadrilateral having four straight angles and equal sides. a parallelogram with two sides that are equally spaced apart and one right angle. the shape of a right-angled rhombus.

A distance of (x+1) is cut in from both sides, so the base dimensions are

18 - 2(x+1) = 16 - 2x

The depth of the fold is (x+1), so that is the depth of the box.

The volume V(x) = (x+1)(16 -2x)²

Answer:

$18

Step-by-step explanation:

Ratios are numerical proportions among different values.

Eg. 1 : 4 is 1 to 4.

Given Total Shares = 1 + 4 = 5 = $90

Jacob gets 1 share.

1 Share = $90 ÷ 5 = $18

Therefore Jacob gets $18.

=======================================================

Explanation:

The compound interest formula is

A = P*(1+r/n)^(n*t)

where,

The deposit amount is P = 10000 dollars.

The value of r here is r = 0.014 which is the decimal form of 1.4%

n = 4 since we're compounding quarterly, i.e. 4 times a year.

The timespan from when Derrick was 15 to when he became 18 is 18-15 = 3 years, which is the value of t.

Summary of input values:

Let's find the value of "A".

A = P*(1+r/n)^(n*t)

A = 10000*(1+0.014/4)^(4*3)

A = 10428.1800719861

A = 10428.18

Using percentages, we know that Emika's monthly budget is $50.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it.

A % is a number without dimensions and without a standard measurement.

For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

So, if we multiply a fraction of a number by 100, you get a percentage. % is the symbol used to denote percentages.

Let x stand in for Emika's monthly cell phone budget.

Divide $60 by 120% to find his monthly spending limit.

x = $60 / 120%

x = $60 / 1.20

x = $50

Therefore, using percentages, we know that Emika's monthly budget is of $50.

the value of arc length = 3.14 and the area of the sector = 4.71cm²

The formula for the area of the sector of a circle is /360° (r2) where r is the radius of the circle and is the angle of the sector.

Arc length is the distance between two points along a section of a curve. It is given as

/360°×2r

= 180°, therefore /3 = 180/3= 60°

arc length = 60°/360 × 2×3.14×3

arc length = 3.14cm

The area of the sector = /360°×r²

60/360×3.14×3²

sector area = 3.14×3÷2

sector area = 4.71cm²

therefore the length of the arc and the area bounded by the arc and radius(sector) is 3.14cm and 4.17cm².

The slope-intercept form of a line 4y - 8x = 12 is y = 2x + 3 and the slope is 2. The graph is attached below.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Given:

4y - 8x = 12

Convert this equation to slope intercept form as shown below,

4y = 8x + 12

y = 8x / 4 + 12 / 4

y = 2x + 3

Here, the slope of the line is 2,

Therefore, the slope-intercept form of a line 4y - 8x = 12 is y = 2x + 3 and the slope is 2. The graph is attached below.

3 tacos and 3 burritos cost $11.25; 4 tacos and 2 burritos cost $10. The difference is 1 more taco and 1 less burrito, for $1.25 less.

So adjust the order repeatedly the same way, adding one taco and taking away one more burrito, and decreasing the cost by $1.25 each time.

3 tacos, 3 burritos, $11.25

4 tacos, 2 burritos, $10.00

5 tacos, 1 burrito, $8.75

6 tacos, 0 burritos, %7.50

The cost of each taco is $7.50/6 = $1.25.

3 of each cost $11.25, so 1 of each cost $3.75; the taco costs $1.25, so the burrito costs $2.50.

Answer:

Answer:

Step-by-step explanation:

You want cost equations and the cheaper company for driving 5 miles when A charges $85 plus $1.50 per mile, and B charges $65 plus $2.50 per mile.

In each case, the cost is the sum of the initial fee and the mileage charge. The mileage charge is the cost per mile, multiplied by the number of miles (x). Using the given fees and costs per mile, we have ...

  A = 85 +1.50x

  B = 65 +2.50x

The difference in fees is $85 -65 = $20. The difference in mileage charges is $2.50 -1.50 = $1.00 (per mile). Then the two companies will charge the same for $20/($1 /mile) = 20 miles.

Five miles is less than that "break even" mileage, so the cheaper company will be the one with the lower initial fee. (The graph shows the charges for each company for 5 miles.) For more than 20 miles, the cheaper company is the one with the lower mileage charge.

Company B will be cheaper for a drive of 5 miles.

Answer:

If Manuel has $20,000 in a savings account that earns 7% interest per year and the interest is not compounded, then after two years he will earn $2,800 in interest. This is because 7% of $20,000 is $1,400, and since the interest is not compounded, this amount will remain constant for each year. Therefore, after two years Manuel will earn a total of $1,400 + $1,400 = $2,800 in interest.

In general, if a savings account earns x% interest per year and the initial amount in the account is y dollars, then after n years the account will earn n * (x/100) * y dollars in interest. For example, if the interest rate is 7% and the initial amount is $20,000, then after two years the account will earn 2 * (7/100) * $20,000 = $2,800 in interest.

Step-by-step explanation:

Answer:

The answer is $2800.

Step-by-step explanation:

Now,

(20000 × 7) ÷ 100 = $1400

Here, we get for 1 year

for two years,

1400 × 2 = $2800

Thus, He will earn $2800 in 2 years.
