The required fraction of the pizza Rachel eat is 1 / 6.

Given that,
After a party, 1/3 of a pizza remains. Rachel eats 1/2 of the remaining pizza. What fraction of a pizza she eat is to be determined.

The technique in mathematics to perform and solve the expression to make the expression simple or more understandable is called simplifying and the process is called simplification.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here, remaining pizza = 1 / 3
Rachel eats 1 /2 of the remaining pizza so,
=  1 / 2 * 1 / 3
= 1 / 6

Thus, the required fraction of the pizza Rachel eat is 1 / 6.

Answer:

a) New price = 0.86 * Original price

b) New price = 0.86 * 48200 = $41452

Step-by-step explanation:

Answer:

Percentage = 14.2%

Step-by-step explanation:

Given the following data;

Cost of plane ticket = £588

Airport tax = $130

£1 = $1.34

To find the percentage of the total cost spent on airport tax;

First of all, we would convert the ticket cost in pounds (£) to dollars ($).

Cost of plane ticket = £588 to $ = 588 * 1.34 = $787. 92

Total cost = Cost of plane ticket + Airport tax

Total cost = 787. 92 + 130

Total cost = $917.92

[tex] Percentage \; cost = \frac {130}{917.92} * 100 [/tex]

[tex] Percentage = 0.1416 * 100 [/tex]

Percentage cost = 14.16 to 1 d.p = 14.2%

Therefore, the percentage of the total cost spent on airport tax by Rimo is 14.2 percent.

Answer:

B) [tex] 10\pi \: cm[/tex]

Step-by-step explanation:

Option B is the correct answer

[tex]A= \pi r^2 [/tex]

[tex]25\pi= \pi r^2 [/tex]

[tex]25= r^2 [/tex]

[tex]\sqrt{25} = r [/tex]

[tex]5\: cm= r [/tex]

[tex]C = 2\pi r [/tex]

[tex]C = 2\pi \times 5[/tex]

In this exercise we will use the differential equations to calculate finances, we find that:

a) [tex]Profit = (x - 3)f(x)[/tex]

b) [tex]P' = f(x) + (x - 1) f'(x)[/tex]

c) [tex]P' = 29400[/tex]

The cost of producing the items is the total expenses of production while the revenue is the amount of money generated from selling the item.

a)Then using the given formula and substituting for the known values ​​we find that;

[tex]Cost = \ cost \ of \ producing \ one \ item * number \ of \ items \ produced\\Cost = $3 * f(x) = 3f(x)\\Revenue = selling \ price \ of \ one \ item * number \ of \ items \ produced\\Revenue = x * f(x) = xf(x)\\Profit = Revenue - Cost = xf(x) - 3f(x)\\Profit = (x - 3)f(x)[/tex]

b) Applying knowledge of differential equations we find that:

[tex]P' = d/dx(xf(x) - 3f(x) )\\P' = f(x) + xf'(x) - f'(x)\\P' = f(x) + (x - 1) f'(x)[/tex]

c)Substituting the known values ​​into the formula given above, we find that:

[tex]f(x) = 3000, x = $45, f'(x) = -600 items / 1$\\P' = 3000 + (45 - 1)(-600)\\P' = 3000 + 26400\\P' = 29400[/tex]

Answer:

The probability that 2 or more of the original 5,100 components may fail during the useful life of the product is:

= 0.001

Step-by-step explanation:

Probability of operating without failure = 0.999

The probability of failed component = 0.001 (1 - 0.999)

The number of components of the electronic office product = 5,100

The number of components that may fail, given the above successful operation = 5.1 (0.001 * 5,100).

Therefore, the probability that 2 or more of the original 5,100 components may fail during the useful life of the product = 0.001

Probability of component failure is the likelihood that a component fails during the useful life of the product.  It is expressed as the number of likely failed components divided by the total number of components.  This result can be left in decimal form or expressed as a percentage.

Following are the solution to the given expression:

[tex]\to \text{p = p (failure)} = 1 -0.999 = 0.001 \\\\[/tex]

We employ the binomial approximation of the normal distribution with mean.

[tex]\to \mu = np = 5100(0.001) = 5.1 \\\\ \to \text{standard deviation} \ (\sigma) = \sqrt{np(1-P)}[/tex]

                                         [tex]= \sqrt{5100(0.001)(1-0.001)} \\\\ = \sqrt{5.1 \times (0.999)} \\\\= \sqrt{5.0949 } \\\\= 2.2572[/tex]

It require [tex]p(x\geq 2)[/tex] but we find [tex]p(x \geq 1.5)[/tex],  because of [tex]0.5[/tex] correction.

Here

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

       [tex]=\frac{1.5-5.1}{2.2572} \\\\ =\frac{-3.6}{2.2572} \\\\ = -1.59 \\\\[/tex]

Calculating the required probability:  

[tex]\to p(z \geq -1.59)[/tex]

[tex]=1+ p(z< 1.59) \\\\= 1+ 0.9440826[/tex] , by standard normal table  

[tex]= 1.9440826 \approx 1.944[/tex]

Answer:

C.

Step-by-step explanation:

Figure A is 5 spaces down reflected off of figure B.

Answer:

Step-by-step explanation:

Suppose F represents the value that a room is unlocked.

Then, we can assume that the probability of unlocked homes is:

P(unlocked homes) = P(U)

P(unlocked homes) = 40%

P(unlocked homes) = 0.40

Also, let us represent the value of the locked room with G.

P(locked homes) = P(G)

P(locked homes) = (1 - 0.40)

P(locked homes) = 0.60

Let the probability of selecting a correct key be P(S)

It implies that for the agent to use 3 keys, we have a combination of [tex]^8C_3[/tex] possible ways for the set of keys.

Now; since only one will open the house, then:

P(select correct key) = P(S)

[tex]P(S) = \dfrac{ (^1_1) (^7_2) }{ ^8_3 }[/tex]

[tex]P(S) = \dfrac{21}{56}[/tex]

P(S) = 0.375

Finally, for the real estate agent to have access to specific homes supposing the agent select three master keys at random prior to the time he left his office, Then:

P(F ∪ (G∩S) = P(F) + P(G∩S)

P(F ∪ (G∩S) = P(F) + P(G) × P(S)

P(F ∪ (G∩S) = 0.40 + (0.60×0.375)

P(F ∪ (G∩S) = 0.40 + 0.225

P(F ∪ (G∩S) =0.625

Answer:

[tex]\frac{x^3}{z^2}[/tex]

Step-by-step explanation:

There are no given values, therefore we can't determine a definite answer. However, we are able to simplify the expression.

As we all know that any variable or number to the power of 0 is equal to 1. This means that [tex]y^0 = 1[/tex].

We also know that a negative power can bring the variable down and make it a fraction. This means that [tex]z^-^2=\frac{1}{z^2}[/tex]

Now that we got these two sorted we are able to write it in a simplified form.

Answer: [tex]\frac{x^3}{z^2}[/tex]

y=485

The rate of the interest on the account is 5.48%. Then the amount of money after 22 years is $485.10.

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

A person invested $150 in an account growing at a rate allowing the money to double every 13 years.

Then the rate will be

[tex]\begin{aligned} 300 &= 150 (1 + r)^{13}\\\\13 \log (1 + r) &= \log 2\\\\\log (1 + r) &= 0.023156\\\\1 + r &= 1.054766\\\\r &= 0.054766 \approx 0.0548 \end{aligned}[/tex]

Then the amount of money after 22 years will be

[tex]\rm Amount = 150(1 + 0.0548)^{22}\\\\Amount = 150 \times 3.234\\\\Amount = \$ \ 485.1[/tex]

Answer:

x=4

and

y=4

Step-by-step explanation:

let -2x+y=-4 ...1

y=1/2x+2 ...2

putting equation 2 in equation 1 we get,

-2x+(1/2x+2)=-4

opening the brackets we get,

-2x+1/2x+2=-4

(-4x+x)/2=-4-2

-3x/2=-6

-3x=-6×2

-3x=-12

x=-12/-3

x=4

putting value of x in equation 2

y=1/2(4)+2

y=2+2

y=4

hence, x=4 and y=4

Answer:

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The height of sunflowers is Normally distributed with mean 50 inches and standard deviation 8 inches.

This means that [tex]\mu = 50, \sigma = 8[/tex]

Percent of all sunflowers that are between 35 and 40 inches tall.

As a proportion, this is the pvalue of Z when X = 40 subtracted by the pvalue of Z when X = 35. So

X = 40

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

[tex]Z = \frac{40 - 50}{8}[/tex]

[tex]Z = -1.25[/tex]

[tex]Z = -1.25[/tex] has a pvalue of 0.1057

X = 35

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

[tex]Z = \frac{35 - 50}{8}[/tex]

[tex]Z = -1.88[/tex]

[tex]Z = -1.88[/tex] has a pvalue of 0.03

0.1057 - 0.03 = 0.0757

As percent: 0.0757*100% = 7.57%
