The probability is P = 0.894

a) Determine the probability that a student will begin college during the summer semester and attend an in-state college.

The probability is given by the quotient between the number of students that start on summer semester and attend to an in-State college, and the total number of students that start on the summer semester.

The number of students starting on the summer semester is:

178 + 21 = 199

Of these 199 students, 178 will attend to an in-state college, so our probability is:

P = 178/199  = 0.894

Answer:

Let

x=sin-¹u

Sinx=u

let y=tan-¹v

tany=v

Substituting

Sin[x + y]

Applying the sine expansion

Sinxcosy + CosxSiny

Recall x =Sin-¹u

y=tan-¹v

Sin(Sin-¹u)Cos(tan-¹v) +Cos(sin-¹u)Sin(tan-¹v)

Now at this point

Here's what you do

For the first expression

Sin(Sin-¹u)

Let's simplify this

Let P = Sin-¹u

Taking sine of both sides

SinP=u

Draw a Right angled angle for this

Since Sine from SOHCAHTOA is OPP/HYP

Where P is the angle and u is the opposite and 1 is the hypotenuse since u is the same as u/1

substituting Sin-¹u = P

You have

Sin(Sin-¹u) = SinP

and from the triangle you drew

SinP = u

Taking the second express

Cos(tan-¹v)

Let Q=Tan-¹v

taking tan of both sides

tanQ=v

Draw a right angled triangle for this too

Since Tan from SOHCAHTOA is OPP/ADJ

Find the Hypotenuse cos you'll need it

Now Let's do the substitution again

We first said tan-¹v = Q

When we substitute it in Cos(tan-¹v)

We have CosQ

Cos Q from the second right angle triangle you drew is 1/√1+v²

Because CAH is adj/Hyp

So

the first part of the original Express

Which is

Sin(Sin-¹u)Cos(tan-¹v) is now simplified to

u(1/√1+v²).

Let's Move to the second part of the Original Expression

Cos(Sin-¹u)Sin(tan-¹v)

From our first solution

We said Sin-¹u= P

So replacing it here

we have Cos(sin-¹u) = CosP

let's leave the second one for now which is sin(tan-1v) We'll deal with this after the first

so Cos(Sin-¹u) = CosP

we can still use our first Right angle triangle for this because the angle was P.

so Cos P from that triangle will be

CosP= √1-u²

Now onto the next

Sin(tan-¹v)

From the Second solution of the first we did

we said let Tan-¹v =Q

Substituting this

we have

Sin(tan-¹v) = SinQ

using the second Right angle triangle because its angle is Q

We have

SinQ= v/√1+v²

Answer for second phase Which is

Cos(sin-¹u)Sin(tan-¹v) = √1-u²(v/√1+v²)

We're done

compiling our answers

The answer to

Sin(Sin-¹u - tan-¹v) = u(1/√1+v²) + [(√1-u²)(v/√1+v²)]

You can still choose to factor out 1/√1+v² since it appears on both sides

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

An inequality is a mathematical statement which compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to show relationships between quantities or to express constraints or conditions.

Answer:

Step-by-step explanation:

here is SOH CAH TOA is  a from to copy and paste into your computer for use for all trig function  problems.  Yes, I mean save the below for use later.

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

now figure out what parts you know and what you want to find, and see which one fits that purpose.

we are given the two legs of the triangle and want to find the hypotenuse. so we don't really need SOH CAH TOA, here,  Pythagoras will come to the rescue.   but still copy the above SOH CAH TOA for use when you will need it.

Pythagoras :   [tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]

where A = 15 and B = 10

 [tex]C^{2}[/tex]  = [tex]15^{2}[/tex] + [tex]10^{2}[/tex]

[tex]C^{2}[/tex]  = 325

Answer:

x=-14

Y=40

Perimeter=(4×14+3)×4=236

Step-by-step explanation:

as long as it's a square then

[tex]3x + 17 = 4x + 3 \\ 4 x - 3x = 3 - 17 \\ x = - 14 \\ \\ any \: angle \: in \: the \: square \: equal \: 90degrees \\ then \\ 5x + 4y = 90 \: \: when \: x = -14 \\ 4y = 5 \times 14 + 90 \\ 4y = 16 \\ y = 40[/tex]

[tex]perimeter =( 4 \times 14 + 3)\times 4 = 236[/tex]

X = 14

Y = 5

The perimeter of the square = 236

It's square so

3x + 17 = 4x + 3

3x + 17 - 4x - 3 = 0

-x + 14 = 0

X = 14

And

5x + 4y = 90, x = 14

5(14) + 4y = 90

70 + 4y = 90

4y = 20

Y = 5

The perimeter of a square is the total length of all the sides of the square, length = 59

The perimeter of the square = 4 × 59 = 236

Step-by-step explanation:

the donkey eats 3/5 of hay bale a week

3/5 x 2 = 6

the donkey eats 6 hay bales in 10 weeks

The amount of bales the donkey eats in 10 weeks is 6 bales.

Given,

A donkey eats three-fifths of a hay bale a week.

We need to find out how many bales he eats in 10 weeks.

Example:

2 miles in 1 hour

2 miles = 1 hour

To find miles in 4 hours we multiply both sides by 4.

4 x 2 miles = 4 x 1 hour

8 miles = 4 hours

We have,

Donkey eats:

3/5 bales = 1 week ____(1)

In 10 weeks:

Multiply 10 on both sides of (1)

10 x 3/5 bales = 10 x 1 week

6 bales = 10 weeks

Thus the amount of bales the donkey eats in 10 weeks is 6 bales.

Answer:

19 pounds of apple was shared and 3 pounds of apple were left to be shared for the students

A

Answer:

D. 22

Step-by-step explanation:

We're looking for the sum of 19 pounds and 3 pounds. The teacher gave out 19 pounds of apples. After giving them out, they had 3 pounds left of the total. To find the total, we need to add those amounts:

19 + 3 = 22

We can check our answer by doing this:

22 - 19 = 3

As you can see, if you had 22 pounds of apples and gave out 19 pounds, you are left with 3 pounds. This is the amount left, as mentioned in the problem. The answer is D.

Answer:

Bella paid a total amount of $13.49.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have,

Bella ordered a $6 smoothie.

Sales tax = 9%

So, amount after tax

= 6 + 9% of 6

= $6.54

and, tip= 15%

Amount after tip

= 6 + 0.15 x 6

= $6.9

Thus, Bella paid

= 6.54 + 6.9

= $13.49
