The approximate number of people per 100 who spelled were correcily is (Type a whole number​

Answer:

Technically, yes. It's called epsilon, which is defined as an infinitely small number. So

 2 + epsilon is the smallest number greater than 2. But for practical purposes no there isn't.

00

Step-by-step explanation:Not without limits. You can always move the .1 one place further from the interring. For example,  

2.1>2.01

and  

2.01>2.001

So, unless there are a limited number of decimal spaces, you can continually add an infinite amount of zeros behind the decimal point, followed by a one.

If you use two or three decimal spaces as a standard in your class, then the smallest decimal greater than 2 would be 2.01 or 2.001, respectively.

Problem 1

If you meant to say [tex]8^4[/tex], then you would have four copies of 8 multiplied together

[tex]8^4 = 8*8*8*8 = 4096[/tex]

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

Problem 2

1/7 full = 1/3 cup of water

7*(1/7 full) = 7*(1/3 cup of water) ... multiply both sides by 7

1 full = 7/3 cup of water

So a full mug has 7/3 cups of water. Let's convert this to a mixed number

7/3 = (6+1)/3

7/3 = 6/3 + 1/3

7/3 = 2 + (1/3)

7/3 = 2 & 1/3

The full capacity of the cup is 7/3 cups or 2 & 1/3 cups

7/3 is the improper fraction form

2 & 1/3 is the mixed number form

One way to think of it is to imagine there are 7 cookies and you want to distribute among 3 friends. We could say 7/3 = 2 remainder 1 meaning each person gets 2 full cookies and there's 1 left over. So that's how we'd get 2 & 1/3.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Here is the picture

If the numbers are consecutive multiples of 6, and you want to call the smallest one ' n ', then the next one is (n+6) and the biggest one is (n+12).

Their sum is (3n + 18).  That's choice-C .

If you run into the same problem again, you might like to call the middle number ' n '.  Then the smallest one is (n-6) and the biggest one is (n+6),

and their sum is just 3n !  This is a lot easier to do in your head.

Answer:

a

[tex]0.716 < p < 0.744[/tex]

b

[tex]0.3498 < p < 0.4089[/tex]

c

 With the result obtained from a and b the manager can be 95 % confidence that the proportion of the population that complained about dirty or ill-equipped bathrooms are within the interval obtained at  a

and that

the proportion of the population that complained about loud or distracting diners at other tables are within the interval obtained at  b

Step-by-step explanation:

From the question we are told that

The sample size is  [tex]n = 1003[/tex]

The number that complained about dirty or ill-equipped bathrooms is [tex]e = 732[/tex]

 The number that complained about loud or distracting diners at other tables is  [tex]q = 381[/tex]

Given that the the confidence level is  95% then the level of significance is mathematically represented as  

         [tex]\alpha = (100- 95)\%[/tex]

         [tex]\alpha = 0.05[/tex]

Next we obtain the critical value of  [tex]\frac{\alpha }{2}[/tex] from the normal distribution table , the value is  

         [tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Considering question a

The sample proportion is mathematically represented as

           [tex]\r p = \frac{e}{n}[/tex]

=>        [tex]\r p = \frac{732}{1003}[/tex]

=>        [tex]\r p = 0.73[/tex]

Generally the margin of error is mathematically represented as

          [tex]E = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{ \r p (1- \r p)}{n} }[/tex]

          [tex]E = 1.96* \sqrt{ \frac{ 0.73 (1- 0.73)}{1003} }[/tex]

          [tex]E = 0.01402[/tex]

The 95% confidence interval is  

        [tex]\r p - E < p < \r p +E[/tex]

        [tex]0.73 - 0.01402 < p < 0.73 + 0.01402[/tex]

        [tex]0.716 < p < 0.744[/tex]

Considering question b

The sample proportion is mathematically represented as

           [tex]\r p = \frac{q}{n}[/tex]

=>        [tex]\r p = \frac{381}{1003}[/tex]

=>        [tex]\r p = 0.3799[/tex]

Generally the margin of error is mathematically represented as

          [tex]E = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{ \r p (1- \r p)}{n} }[/tex]

          [tex]E = 1.96* \sqrt{ \frac{ 0.3799 (1- 0.3799)}{1003} }[/tex]

          [tex]E = 0.0300[/tex]

The 95% confidence interval is  

        [tex]\r p - E < p < \r p +E[/tex]

        [tex]0.3798 - 0.0300 < p < 0.3798 + 0.0300[/tex]

        [tex]0.3498 < p < 0.4089[/tex]

Answer: the cost of a similar scientific calculate in 2019 will be $19.01

Step-by-step explanation:

Given that;

in 1970 cost of S.C = $96.50

in 2016 cost of same calculator = $21

In 2019 cost of a similar calculator = ?

Assuming the exponential decay model applies

dN/dt = -λN

we know that λ is the decay constant

⇒ N(t) = N₀e^-λt

N(t) is price at time t year, N₀ is initial price,

so t = 0 in 1970 thus N₀ = 96.50

also t = 46 in 2016 thus N₄₆ = 21

substituting into our initial expression

N(t) = N₀e^-λt

N(46) = N₀e^-λ×46

21 = 96.50e^-46λ ⇒ In 21/96.50 = -46λ

= -1.5250 = - 46λ

λ = -1.5250 / -46

λ = 0.03315

t = 0 in 1970 thus N₀ = 96.50

also t = 49 in 2019 thus N₄₉ = ?

so

using our initial expression again

N(49) = N₀ e^-49λ

= 96.5 × e^ (-49 × 0.03315 )

= 96.5 × 0.197014404

= 19.01189 ≈ 19.01

therefore the cost of a similar scientific calculate in 2019 will be $19.01

Answer:

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = ((- 2, 3) and (x₂, y₂ ) = (4, 1)

m = [tex]\frac{1-3}{4+2}[/tex] = [tex]\frac{-2}{6}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 3), then

3 = [tex]\frac{2}{3}[/tex] + c ⇒ c = 3 - [tex]\frac{2}{3}[/tex] = [tex]\frac{7}{3}[/tex]

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/tex] ← equation of line

Complete Question

A boat sails 4km on a bearing of 038 degree and then 5km on a bearing of 067 degree.(a)how far is the boat from its starting point.(b) calculate the bearing of the boat from its starting point

Answer:

a)8.717km

b) 54.146°

Step-by-step explanation:

(a)how far is the boat from its starting point.

We solve this question using resultant vectors

= (Rcos θ, Rsinθ + Rcos θ, Rsinθ)

Where

Rcos θ = x

Rsinθ = y

= (4cos38,4sin38) + (5cos67,5sin67)

= (3.152, 2.4626) + (1.9536, 4.6025)

= (5.1056, 7.065)

x = 5.1056

y = 7.065

Distance = √x² + y²

= √(5.1056²+ 7.065²)

= √75.98137636

= √8.7167296826

Approximately = 8.717 km

Therefore, the boat is 8.717km its starting point.

(b)calculate the bearing of the boat from its starting point.

The bearing of the boat is calculated using

tan θ = y/x

tan θ = 7.065/5.1056

θ = arc tan (7.065/5.1056)

= 54.145828196°

θ ≈ 54.146°

Answer:

Step-by-step explanation:

1. Subtract 9:

  -10 < n < 8

__

2. Add 12, then divide by 8:

  10 < 8x ≤ 48

  10/8 < x ≤ 6

  5/4 < x ≤ 6 . . . . . with the fraction reduced

_____

The rules of equality allow us the do these operations, provided that we do them to all parts of the compound inequality. That is, when we say "subtract 9", we mean ...

  -1 -9 < 9 +n -9 < 17 -9

This simplifies to the inequality we show above:

  -10 < n < 8

Answer:

Purchase Price = $150 and Total Price = $162

Step-by-step explanation:

Purchase price = Tax Amount / Tax Percentage (as decimal)

Purchase Price = $12 / .08

Purchase Price = $150

Total Price = Purchase Price + Tax

Total Price = 150 + 12 = $162

[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]

Step-by-step explanation:

From the information given:

The probability that at least 2 crashes occurs in the next month can be estimated by using Poisson distribution because the sample size is large and the probability of the event p = 0.0035 is rare.

∴

Let X be the random variable that follows a Poisson  distribution

The probability that at least 2 crashes occurs in the next month is:

[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]

Answer:

x = 6, y = -2, z = 0

Step-by-step explanation:

To find x, we have to plug 0 into f(x). Therefore, x = f(0) = 2 * 0² - 8 * 0 + 6 = 6. Similarly, to find y, we have to plug 2 into f(x) so y = f(2) = 2 * 2² - 8 * 2 + 6 = -2. Finally, z = f(3) = 2 * 3² - 8 * 3 + 6 = 0.

Answer:

a

   No singular point due to the exponent in the solution

    The interval is   [tex]-\infty  <0 <  \infty[/tex]

b

   NONE

Step-by-step explanation:

From the question we are told that

     [tex]\frac{dy}{dx} =  9y[/tex]

The generally solution is mathematically represented as

         [tex]\frac{dy }{dx}  =  9y[/tex]

=>       [tex]\frac{dy}{y}  =  9dx[/tex]

integrating both sides  

         [tex]\int\limits  {\frac{ dy}{y} } \,  = \int\limits  {9} \, dx[/tex]

  =>   [tex]lny = 9x + c[/tex]

 =>   [tex]y =  e^{9x +c }[/tex]

 =>    [tex]y =  e^{9x} e^{c}[/tex]

Here [tex]e^c  =  C[/tex]

=>     [tex]y = C  e^{9x}[/tex]

From the above equation we see that the domain for x has no singular point the interval is

       [tex]-\infty  <0 <  \infty[/tex]

Also there is no transient term in the general solution obtained because as  [tex]x \to \infty[/tex] there no case where [tex]y \to 0[/tex]
