Answer: Sally baked 11 cakes

Step-by-step explanation:

Alright, so you should go about solving this by setting up two equations. We will use b to represent Brad and s to represent Sally:

b+s=27

b=s+5 (because Brad made 5 more cakes than sally)

Solve using systems of equations. I will show the substitution method because it is faster in this scenario:

(s+5)+s=27

Solve for s:

s+5+s=27

2s=22

s=11

So Sally baked 11 cakes, which makes sense because that means that Brad baked 16

Answer:

8n= $ He makes

Step-by-step explanation:

8 dollars is our unit rate, so it makes sense to multiply it by the N.

By unitary method we can say that it is better to buy the 4 inch radius pizza for $3.

According to the given question.

The price of 4 inch radius pizza = $3

And, the price of 8 inch radius pizza = $14

As we know that, the unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Therefore, by unitary method.

Cost of 1inch radius pizza, when the price of 4 inch radius pizza is $3

= 3/4

= $0.75

And the cost of 1 inch radius pizza, when the price of 8 inch radius pizza is $ 14

= 14/8

= $ 1.75

Hence, by unitary method we can say that it is better to buy the 4 inch radius pizza for $3.

Answer:

14n^2.

Step-by-step explanation:

This is Arithmetic with first term a =  14 and common difference d =  28.

Sum of n terms = n/2[2a + (n-1)d]

= n/2(28 +( n -1)28]

= n/2(28 + 28n - 28)

= 14n^2

Answer:

14n²

Step-by-step explanation:

14 = 14 *1

42 = 14 *3

70 = 14 *5

28n -14 = 14*2n - 14 = 14*(2n -1)

14 + 42 + 70 + ........+(28n -14) = 14*1  + 14*3  + 14*5 + ....... + 14*(2n - 1)

                                               = 14 * (1 + 3 + 5 + ......+ (2n-1) )

                                               = 14 * n²

                                               = 14n²

1 + 3 + 5 + .... +(2n -1)  ->  sum of first 'n' odd numbers.

Formula for finding sum of first 'n' odd numbers  = n²

Answer: The transformation of an object is a great example of how the object can be shown in many different forms but all of the meanings are the same thing.

Step-by-step explanation:

Some of the examples of situations of transformation where the image of the object appear different but they still mean the same thing like

-The rigid transformation of geometric and three-dimensional shapes.

-The transformation of bank notes to an electronic form of money.

-The transformation of liquid water to ice and steam.

-The transformation of cube sugar to granulated sugar.

When you're talking about mathematical terms of transformation, even if the polygon is in many different size and shapes on the graph, it's still technically a polygon.

So if you have seen something that appears different, but its meaning remains the same, it could most likely be a transformation or many other terms.

The value of r = 9.078.

pv = nrt. The factor “r” in the ideal gas law equation is known as the “gas constant”. r = \(\frac{pv}{nt}\). The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number.

so the student weights out .0422 grams of the magnesium metal so from here we can calculate that more's, the magnesium that he used, that is the mass of the magnesium over the more mass, which is .024422 over 24 point. That's equal to about .001758. More so also, it says the magnesium metal is react with excessive hydrochloric acid and produce hydrogen gas. A sample of the hydrogen gas is collected over water in a meter at 22 cecr, the volume of clictic gas is 43.9 and mastic pressure. Is that so using the experimental and collected data calculated are in the percent error? So we know the magnesium react with hydrochloride. The reaction ratio is 1 to 2 and we produce 1. More is the hydrogen and 1. More is magnesium chloride. So from this equatium we know that more of the hydrogen that would be produced in this case is equal to the mass of the magnesium here, that's his .001758 more and set way. There's among hydrogen. The temperature is 32 (degree celcius) which we need to convert the unit into kelvin, so it's actually about field 5.15 kelvin and tells you. The volume of the gas is 43.9 in ml, which is .0439 liter and tells you the pressure of the gas is about 832 millimeter. Mercury, which is a 2 times 13332 plus ca, that's equal to about 110922.24 par. So in this case we know p v = n r t.

r = \(\frac{pv}{nt}\)

So p = 110922.24. V = 0.0439 , n = 0.001758 t =  305.15. So let's just do the calculations here.

In this case you will find r=?

Step-by-step explanation:

let's look at the last line :

x³ + 8x - 3 = Ax³ +5Ax + Bx² + 5B + Cx + D

since we find A, B, C, and D by simply comparing the factors of the various terms in x (or constants) in both sides of the equation, we need to combine a few terms on the right hand side (so that we have one term per x exponent grade).

x³ + 8x - 3 = Ax³ + (5A + C)x + Bx² + (5B + D)

by comparing now both sides, to make both sides truly equal, the factors have to be equal.

A = 1 (the same as for x³ on the left hand side).

B = 0 (a we have no x² on the left side).

5A + C = 8 (a 8 is the factor of x in the left side).

5×1 + C = 8

5 + C = 8

C = 3

5B + D = -3 (as the constant term is -3 on the left side).

5×0 + D = -3

D = -3

Answer: 0.49 ± 0.0237

Step-by-step explanation: A interval of a 99% confidence interval for the population proportion can be found by:

\(p_{hat}\) ± z.\(\sqrt{\frac{p_{hat}(1-p_{hat})}{n} }\)

\(p_{hat}\) is the proportion:

\(p_{hat}\) = \(\frac{1455}{2957}\)

\(p_{hat}\) = 0.49

For a 99% confidence interval, z = 2.576:

0.49 ± 2.576.\(\sqrt{\frac{0.49(1-0.49)}{2957} }\)

0.49 ± 2.576.\(\sqrt{\frac{0.49*0.51}{2957} }\)

0.49 ± 2.576.(0.0092)

0.49 ± 0.0237

For a 99% confidence interval, the proportion will be between 0.4663 and 0.5137 or 0.49 ± 0.0237

Answer:

x = 57

Step-by-step explanation:

XZ divides <WXY into two equal parts. Which implies that:

m<ZXY = m<ZXW

Therefore:

m<WXY = 2(m<ZXY)

m<ZXY = 58°

m<WXY = 2x + 2

Plug in the values into the equation

2x + 2 = 2(58)

2x + 2 = 116

2x = 116 - 2 (subtraction property of equality)

2x = 114

x = 114/2 (division property of equality)

x = 57

The sum of the probabilities is not equal to one, the table does not represent a probability distribution, so option D is the correct answer.

The statement that explains that the table does not represent a probability distribution is D. The sum of the probabilities is 8/3.

This statement explains that the probabilities do not add up to one, which is a requirement for a probability distribution. Therefore, it is not a probability distribution. If a table is given with probabilities and it is required to identify whether it represents a probability distribution or not, we must check the probabilities whether they meet the following conditions or not.

The sum of all probabilities should be equal to 1.All probabilities should be greater than or equal to zero.If any probability is greater than 1, then it is not a probability, so the probability table does not represent a probability distribution.The given probabilities have different denominators, this condition alone is not enough to reject it as probability distribution and is also a common error while creating the probability table.

An event's probability is a numerical value that reflects how likely it is to occur. Probabilities are always between zero and one, with zero indicating that the event is impossible and one indicating that the event is certain.

The sum of the probabilities of all possible outcomes for a particular experiment is always equal to one.The probabilities in the table represent the likelihood of the event happening and must add up to 1.

For example, the probability of rolling a die and getting a 1 is 1/6 because there are six possible outcomes and only one of them is a 1.The probability distribution can be used to determine the likelihood of certain outcomes. The sum of all probabilities must be equal to one.

The probability distribution function is also used in statistics to calculate the mean, variance, and standard deviation of a random variable. A probability distribution that meets the required conditions is called a discrete probability distribution. It is a distribution where the probability of each outcome is defined for discrete values.

The variance of a binomial distribution with parameters n and p cannot exceed n/2.

The binomial distribution is characterized by two parameters: n, which represents the number of trials, and p, which represents the probability of success in each trial. The variance of a binomial distribution is given by Var(X) = np(1-p).

To prove that the variance cannot exceed n/2, we can start by analyzing the expression np(1-p). Rearranging the terms, we have np - np^2. Since p^2 is always non-negative, np - np^2 is maximized when p is equal to 0.5 (the midpoint between 0 and 1).

When p is equal to 0.5, the expression np(1-p) simplifies to 0.25n, which is n/4. This implies that the maximum value of the variance is n/4.

Since n/4 is smaller than n/2 for any positive value of n, we can conclude that the variance of a binomial distribution with parameters n and p cannot exceed n/2.

Therefore, the variance of a binomial distribution is bounded above by n/2, indicating that as the number of trials increases, the variability or spread of the distribution is limited.
