The trip is 50 miles

Step-by-step explanation:

30 = (60/100)T

T = (10/6)(30) = (5/3)(30) = 50 miles

let the numbers be x

x-6-5=2x

Answer:

x - 6 = 2x + 5

Step-by-step explanation:

Let's break down the statement.

A number decreased by six means a number/variable subtracted by six. So, we have x - 6.

Five more than twice a number means five plus two times a number/variable. So, we have 2x + 5.

The 'is' in the middle of the statement signifies that they are equal to each other.

The equation would be x - 6 = 2x + 5.

Hope that helps.

Answer:

A. S(t) = 50 [3 ln t/ln2 +1]

Step-by-step explanation:

We are told that the rate of change in sales S is inversely proportional to time.

Thus;

dS/dt = k/t

Where k is the constant of proportionality.

So,

dS = (k/t)dt

Integrating both sides gives us;

S = (kIn t) + C

We are given that after 2 and 4 weeks are 200 units and 350 units respectively.

Thus;

S(2);

(k In 2) + C = 200 - - - (eq 1)

(k In 4) + C = 350 - - - -(eq 2)

To find k, let's subtract eq 1 from eq 2 to get;

(k In 4) - (k In 2) = 350 - 200

(k In 4) - (k In 2) = 150

k(In 4 - In 2) = 150

0.6931k = 150

k = 150/0.6931

k = 216.42

Plugging this for k in eq 1 gives;

(216.42 In 2) + C = 200

C = 200 - 150

C = 50

Thus;

S(t) = (216.42In t) + 50

Now 216.42 can also be expressed as;

150/In 2

Thus;

S(t) = ((150/In 2)In t) + 50

Factorizing out gives;

S(t) = 50 [(3 ln t/ln2) + 1]

Fourth one or right one at the bottom  rectangular prism has a volume equal to the expression 6 × 3 × 4 cubic unit.

" Volume is total amount of space occupied by any three dimensional body."

Formula used

Volume of rectangular prism = Length × width ×height

According to the question,

Compare the expression of given volume with given diagrams

Given volume = 6 ×3×4

From the diagram we can conclude that right one at the bottom has length = 6 units, width = 3 units and height = 4 units.

Hence, Option(D) or right one at the bottom  is the correct answer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

From the given information:

The null hypothesis is:

[tex]H_o: \mu = 8[/tex]

The alternative hypothesis is:

[tex]H_1 : \mu \ne 8[/tex]

The sample size n = 35

Sample mean = 7.91

variance = 0.03

Standard deviation = [tex]\sqrt{0.03} = 0.173[/tex]

The t-test statistics is computed as:

[tex]t = \dfrac{\bar x - \mu}{\dfrac{s}{\sqrt{n}}}[/tex]

[tex]t = \dfrac{7.91 -8}{\dfrac{0.1732}{\sqrt{35}}}[/tex]

[tex]t = \dfrac{-0.09}{\dfrac{0.1732}{5.916}}[/tex]

t = - 3.0741

Degree of freedom:

df = n - 1

df = 35 - 1

df = 34

Level of significance = 1 - C.I

= 1 - 0.99

= 0.01

The t_{critical} value for the two-tailed test at 0.01 is within the rejection region:

[tex]t_{critical} = -2.728 \ and \ 2.728[/tex]

Decision rule: To reject [tex]H_o[/tex] if  [tex]t< -2.728 \ or \ t > 2.728[/tex]

As [tex]t_{statistics}[/tex] fails the rejection region, we reject [tex]H_o[/tex]

Conclusion: There is sufficient evidence to believe that the machine will not dispense 8 ounces & and it must be stopped for repairs.

You can use hypothesis testing with t test to know if there is enough evidence that he machine should be stopped and production wait for repairs.

There is enough evidence that the machine should be stopped and production wait for repairs.

Let the population mean be denoted by [tex]\mu[/tex]

Null hypothesis: [tex]\mu = 8[/tex] (that is, machine needs no repair and working fine)

Alternate hypothesis: [tex]\mu \neq 8[/tex] (that is, machine is not dispensing right amount and need repairs)

Using t test:

[tex]t = \dfrac{\overline{x} - \mu}{\dfrac{s}{\sqrt{n}}}[/tex]

[tex]t = \dfrac{7.91- 8}{\dfrac{0.1732}{\sqrt{35}}} = -0.30821[/tex]

Degree of freedom = sample size - 1 = 34

Level of significance = [tex]\alpha = 1 -0.99 = 0.01[/tex]

From t tables we have:

[tex]t_{critical} = t_{0.01} = \pm 0.278[/tex] (two tailed test) (at 34 degree of freedom)

Since obtained value of t -0.30821 is less than the minimum value of range [tex](-0.278, 0.278)[/tex], thus lying outside the range and thus, we cannot accept the null hypothesis and end up accepting the alternate hypothesis.

Thus, there is enough evidence that the machine should be stopped and production wait for repairs.

Raising both sides to the [tex]n^{th}[/tex] - [tex]z^{n} =r^{n} *[cos(n*[/tex]θ[tex])+i*sin(n*[/tex]θ[tex])][/tex]

Answer:

Step-by-step explanation:

Let s, d, t represent the numbers of singe, double, and triple cones sold. The problem statement tells us three relationships.

  s + d + t = 52 . . . . . . Danielle sold 52 cones one day

       d -2t = 2 . . . . . . . doubles is 2 more than twice the number of triples

  0.89s +1.19d +1.39t = 58.98 . . . . total amount of sales

__

There are many ways to solve this set of equations. A graphing calculator can quickly tell you the solution is ...

  (s, d, t) = (17, 24, 11)

__

If you want to solve this by hand, it may work well to use substitution.

The second equation gives an expression for d:

  d = 2t +2

The first equation gives an expression for s that can be written in terms of t.

  s = 52 -d -t

  s = 52 -(2t +2) -t = 50 -3t

Using these in the last equation, we have ...

  0.89(50 -3t) +1.19(2t +2) +1.39t = 58.98

  1.10t = 12.10 . . . . . . . . collect terms, subtract 46.88

  t = 11 . . . . . . . . . . . . . . divide by 1.10

  d = 2(11) +2 = 24

  s = 50 -3(11) = 17

Answer:

[tex]a_{61}=-972[/tex]

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

Where

an = nth term

a1 = first term

r   = common difference

n  = number of the term

We are given the first terms of a sequence:

-12, -28, -44,...

Find the common difference by subtracting consecutive terms:

r = -28 - (-12) = -16

r = -44 - (-28) = -16

The first term is a1 = -12. Now we calculate the term n=61:

[tex]a_{61}=-12+(61-1)(-16)[/tex]

[tex]a_{61}=-12-60*16=-12-960[/tex]
