Answer:

49 odd numbers are there between 101 and 199.

Step-by-step explanation:

Given  : 101 and 199.

To find : How many odd integers are there between 101 and 199.

Solution : We have given  101 and 199.

Total number(N) between 101 and 199

N = 199 - 101 = 98

N = 98 .

We can see 98 is even number so, there are half numbers are odd and half numbers are even .

Odd number = [tex]\frac{N}{2}[/tex].

Odd number =  [tex]\frac{98}{2}[/tex].

Odd number = 49.

Therefore, 49 odd numbers are there between 101 and 199.

Answer:

The answer is option C.

Step-by-step explanation:

Here, according to the given question, margin of error means that the number of people who rated the vacation as 'delightful' ranges between 81% (83-2) and 85% (83+2) of the population at a 95% confidence interval. The range is formed as 81% to 85% as its given that the margin of error is ±2% .

Therefore, only option C is having both the ranges, 81% and 85%. So, option C is the correct answer.

C.It can be concluded, with 95% confidence, that between 81% and 85% of all employees will rate the vacation policy as "delightful."

Final answer:

Ursula, swimming at 60 meters per minute, and given Andre a 1-minute head start who swims at 48 meters per minute, will catch up to Andre 4 minutes after she starts.

Explanation:

Ursula and Andre competed against each other in a swimming race. Ursula swam at a rate of 60 meters per minute and Andre swam at a rate of 48 meters per minute. Ursula gave Andre a 1-minute head start. To determine who wins the race, we need to calculate the time it takes for Ursula to catch up to Andre, given the head start.

Let's denote the time it takes for Ursula to catch up to Andre as t (in minutes). Since Andre has a 1-minute head start, he would have swum 48 meters before Ursula starts. Therefore, the distance Andre swims in t+1 minutes is 48(t+1). Ursula's swimming distance in t minutes is 60t.

To find out when Ursula catches up to Andre, we set these distances equal to each other:

Thus, Ursula will catch up to Andre 4 minutes after she starts swimming, which is 5 minutes after Andre starts.

Final answer:

The trigonometric identity (tan(x) + tan(y)) / (1 - tan(x)tan(y)) = (sin(x)cos(y) + cos(x)sin(y)) / (cos(x)cos(y) - sin(x)sin(y)) can be verified by using the angle addition formulas for sine and cosine, and by applying the tangent sum formula. Both sides reduce to tan(x + y), confirming the identity.

Explanation:

The given trigonometric identity to verify is:
(tan(x) + tan(y)) / (1 - tan(x)tan(y)) = (sin(x)cos(y) + cos(x)sin(y)) / (cos(x)cos(y) - sin(x)sin(y)).

Trigonometric identities are equations involving trigonometric functions that are true for all values of the occurring variables where both sides of the equation are defined.

Let's verify the given identity step by step. First, rewrite the right-hand side using the angle addition formulas for sine and cosine:

So, the right-hand side can be written as sin(x + y) / cos(x + y). This is equivalent to tan(x + y).

Now, let's examine the left-hand side and apply the tangent sum formula:

As we can see, the left-hand side is exactly the tangent sum formula; therefore it also simplifies to tan(x + y).

Since tan(x + y) is a common form for both sides of the identity, we can conclude that the identity is verified:

(tan(x) + tan(y)) / (1 - tan(x)tan(y)) = sin(x + y) / cos(x + y)

Answer:

g(x) increase at a faster rate.

Step-by-step explanation:

Given : Two functions  [tex]f(x)=x^2[/tex] or [tex]g(x)=2^x[/tex]

To find : Which function increase at a faster rate on 0 to infinity

Solution :

We put some value of x in the functions and note down the observation.

            x               →  0      1      2       3       4        5        6         7      

[tex]f(x)=x^2[/tex]  →  0      1       4      9      16       25       36      49

[tex]g(x)=2^x[/tex] →   1      2      4       8      16        32      64      128

Comparing the values of f(x) and g(x), we can see that that g(x) increases at a faster rate on 0 to infinity.

Reason - The exponential function, g(x), has a constant multiplicative rate of change and will increase at a faster rate than the quadratic function f(x).

Answer:

72 is the og

Step-by-step explanation:

72*.17=12.24

The original cost of the meal is $72.

In mathematics →

Given is that Sally left a $12.24 tip that represented 17% of her bill.

Assume that the original cost of the meal is $[x]. So, we can write -

12.24 = 17% of {x}

12.24 = (17/100) × {x}

{x} = (12.24 x 100)/17

{x} = 1224/17

{x} = 72

Therefore, the original cost of the meal eaten by Sally is $72.

Answer:  The vertex form of the given function is [tex]y=5\left(x+\dfrac{3}{2}\right)^2-\dfrac{53}{4}[/tex] and its axis of symmetry is [tex]x=-\dfrac{3}{2}.[/tex]

Step-by-step explanation:  The given quadratic function is

[tex]y=5x^2+15x-2~~~~~~~~~~~~~~(i)[/tex]

We are to rewrite the above function in vertex form and to determine its axis of symmetry.

We have from equation (i),

[tex]y=5x^2+15x-2\\\\\Rightarrow y=5(x^2+3x)-2\\\\\Rightarrow y=5\left(x^2+2\times x\times \dfrac{3}{2}+\dfrac{9}{4}\right)-\dfrac{45}{4}-2\\\\\Rightarrow y=5\left(x+\dfrac{3}{2}\right)^2-\dfrac{45+8}{4}\\\\\Rightarrow y=5\left(x+\dfrac{3}{2}\right)^2-\dfrac{53}{4}.[/tex]

So, the given function is a parabola with vertex at the point [tex]\left(-\dfrac{3}{2},-\dfrac{53}{4}\right).[/tex]

Therefore, the axis of symmetry is given by

[tex]x=-\dfrac{3}{2}.[/tex]

Thus, the vertex form of the given function is [tex]y=5\left(x+\dfrac{3}{2}\right)^2-\dfrac{53}{4}[/tex] and its axis of symmetry is [tex]x=-\dfrac{3}{2}.[/tex]

To convert the quadratic function y = 5x² + 15x - 2 into vertex form, completing the square yields y = 5(x + 1.5)² - 13.25, with an axis of symmetry at x = -1.5.

To rewrite the quadratic function y = 5x² + 15x - 2 in vertex form and find the axis of symmetry, follow these steps:

Complete the square

Start with the given quadratic function:

y = 5x² + 15x - 2

To complete the square, first factor out the coefficient of x² (which is 5):

y = 5(x² + 3x) - 2

Now, focus on the expression inside the parentheses, x² + 3x.

To complete the square, need to add and subtract a constant term that will make it a perfect square trinomial.

add (3/2)² = 2.25 and subtract the same value inside the parentheses:

y = 5(x² + 3x + 2.25 - 2.25) - 2

Simplify the expression inside the parentheses

Now, simplify the expression inside the parentheses:

x² + 3x + 2.25 = (x + 1.5)²

So, the equation becomes:

y = 5[(x + 1.5)² - 2.25] - 2

Distribute the 5 and simplify further

y = 5(x + 1.5)² - 5(2.25) - 2

Rewrite in vertex form

y = 5(x + 1.5)² - 11.25 - 2

y = 5(x + 1.5)² - 13.25

Now, the quadratic function is in vertex form:

y = 5(x + 1.5)² - 13.25

Find the axis of symmetry

The axis of symmetry of a parabolic equation in the form y = a(x - h)² + k is given by x = h.

The axis of symmetry is x = -1.5 (opposite sign of the value inside the parentheses).

Therefore, the axis of symmetry for the quadratic function y = 5x² + 15x - 2 is x = -1.5.
