Answer:

  ending balance = $623.02

Step-by-step explanation:

Amounts you spend get subtracted from your bank balance. Amounts you earn get added.

Your ending balance is ...

  ending balance = beginning balance - expenses + earnings

  ending balance = $1250.33 -(184.59 +654.50 +112.11) +323.89

  ending balance = $623.02

Using the normal distribution, it is found that there was a 0.9579 = 95.79% probability of a month having a PCE between $575 and $790.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 700, \sigma = 50[/tex].

The probability of a month having a PCE between $575 and $790 is the p-value of Z when X = 790 subtracted by the p-value of Z when X = 575, hence:

X = 790:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{790 - 700}{50}[/tex]

Z = 1.8

Z = 1.8 has a p-value of 0.9641.

X = 575:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{575 - 700}{50}[/tex]

Z = -2.5

Z = -2.5 has a p-value of 0.0062.

0.9641 - 0.0062 = 0.9579.

0.9579 = 95.79% probability of a month having a PCE between $575 and $790.

would now be

(-1,1) (-4,1) (-4,3) because it's reflected

Answer:

The price per roll for Lidal and Oldi shop is 0.35 and 0.36 respectively.

Therefore Lidal shop is the best value for money.

Given,

Lidal shop:

8 rolls costs  2.80

∴ one roll costs = 2.80/8

                        = 0.35

Oldi shop:

9 rolls costs 3.24

∴ one roll costs = 3.24/9

                        = 0.36

Hence we get the per price for the shops as 0.35 and 0.36

we can see that for lidal shop if per roll it is 0.35 then if a person wants to buy 9 rolls then it will cost him 3.15, whereas in the case of oldi shop the price for 9 rolls is 3.24.Therefore, lidal shop is the best value for money.

Answer:

D

Step-by-step explanation:

Answer:

A = 120

Step-by-step explanation:

To find angle A we will need to use the law of cosines, since we know the three sides of the triangle.

a^2=b^2+c^2−2*b*c*cosA

(2 sqrt(13)) ^2 = 6^2 + 2^2  + 2 * 6 * 2 cos A

4*13 = 36 + 4 - 24 cos A

52 = 40- 24 cos A

12 = -24 cos A

-1/2 = cos A

Take the inverse cos of each side

cos^-1(-1/2) = cos^-1(cos A)

120 = Cos A  or 240 = Cos A

A cannot be greater than 180 so A = 120

Answer:

A = 120°

Step-by-step explanation:

We can use the cosine rule to solve for angle A, since lengths of all sides are known:

[tex]a^2 = b^2+ c^2 - 2(b)(c) \space\ cos A[/tex]

where a, b, and c are the sides opposites angles A, B, and C respectively.

∴ a = 2√3 , b = 6, c = 2

• Rearranging the formula to make A the subject:

[tex]2(b)(c) \space\ cos A = b^2 + c^2 -a^2[/tex]

⇒  [tex]cos A = \frac{b^2 + c^2 -a^2}{2(b)(c)}[/tex]

⇒  [tex]A = cos^{-1}(\frac{b^2 + c^2 -a^2}{2(b)(c)} )[/tex]

• Now we can substitute the values into the equation to calculate the value of angle A:

[tex]A = cos^{-1}(\frac{6^2 + 2^2 -(2\sqrt{13})^2}{2(6)(2)} )[/tex]

⇒  [tex]A = cos^{-1} (-\frac{1}{2} )[/tex]

⇒  A = 120°

Using the z-distribution, the 95% confidence interval for the population proportion is (0.5791, 0.7133).

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The other parameters are given as follows:

[tex]n = 195, \overline{p} = \frac{126}{195} = 0.6462[/tex]

Hence the bounds of the interval are:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6462 - 1.96\sqrt{\frac{0.6462(0.3538)}{195}} = 0.5791[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6462 + 1.96\sqrt{\frac{0.6462(0.3538)}{195}} = 0.7133[/tex]

If the three postal workers sort the mail together or work in parallel, it will take them 15 minutes.

Parallel working refers to the system that can process a common task simultaneously by many workers communicating with one another.

When workers perform the same task together, they tend to achieve greater speed, unlike when they work individually without communicating.

Time to sort a stack of mail by A = 45 minutes or 1/45

Time to sort a stack of mail by B = 25 minutes or 1/25

Time to sort a stack of mail by C = 1/225

Time for the three workers to sort the stack together = 1/45 + 1/25 + 1/225
