To explain what 27 times 13 means, look at it as 27 added together 13 times. To get the answer, you could just write down the number 27, 13 times and then add the 27 numbers together.
If you have one of those old-fashioned handheld calculators, you can double check that the answer is 351 by pressing 27, then x, then 13, and then = to get the answer.
Answer:
\(351\)
Step-by-step explanation:
\(27\times \:13\)
Step 1: Line up the numbers; Multiply the top number by the bottom number one digit at a time starting with the ones digit (from right to left)
\(\begin{matrix}\space\space&2&7\\ \times \:&1&3\end{matrix}\)
Step 2: Multiply the top number by the bolded digit of the bottom number
\(\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}\)
Step 3: Multiply the bold numbers; Carry 2 to the column on the left and write 1 in the result line
\(7\times \:3=21\\\\\frac{\begin{matrix}\space\space&2&\space\space\\ \space\space&2&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&\space\space&1\end{matrix}}\)
Step 4: Add the carried number to the multiplication
\(2+2\times \:3=8\\\\\frac{\begin{matrix}\space\space&\textbf{2}&\space\space\\ \space\space&\textbf{2}&7\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}\)
Step 5: Multiply the top number by the bolded digit of the bottom number
\(\frac{\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}\)
Step 6: Multiply the bold numbers
\(7\times \:1=7\\\\\frac{\begin{matrix}\space\space&\space\space&2&\textbf{7}\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&\space\space&7&\space\space\end{matrix}}\)
Step 7: Multiply the bold numbers
\(2\times \:1=2\\\\\frac{\begin{matrix}\space\space&\space\space&\textbf{2}&7\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&2&7&\space\space\end{matrix}}\)
Step 8: Add the rows. Add zero for simplicity
\(\frac{\begin{matrix}\space\space&\space\space&2&7\\ \space\space&\times \:&1&3\end{matrix}}{\begin{matrix}\space\space&0&8&1\\ \space\space&2&7&0\end{matrix}}\)
\(81 + 270 = 351\)
Therefore 27 times 3 is 351

of households watch a certain television series on a regular basis. Estimate the probability that fewer than 70 in a random sample of 400 households are watching the series on a regular basis. Use Excel to find the probability, rounding your answer to four decimal places. Provide your answer belowr
Probability that fewer than 70 households in a sample of 400 are watching the series on a regular basis is approximately 0.9991.
What is probability?
Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.
To find the probability that fewer than 70 in a random sample of 400 households are watching the series on a regular basis, we can use the binomial distribution.
The probability of observing x successes in a sample of size n with probability p of success is given by the following formula:
\(P(x) = (n choose x) * p^x * (1 - p)^(n-x) \\\)
In this case, we can set n = 400, p = 0.2, and x = 70. Plugging these values into the
gives us:
P(x < 70) = P(x = 0) + P(x = 1) + ... + P(x = 69)
To calculate P(x = 0), P(x = 1), etc., we can use a loop in Excel to calculate the probability for each value of x from 0 to 69.
The probability that fewer than 70 households in a sample of 400 are watching the series on a regular basis is then given by the sum of these probabilities.
Rounding to four decimal places, the probability that fewer than 70 households in a sample of 400 are watching the series on a regular basis is approximately 0.9991.

In order for the relationship zyx ~ wvu to be correct, the following conditions must be true:
Corresponding angles are congruent: The angles formed by matching vertices should have the same measures in both triangles. This ensures that the corresponding angles are equivalent.
Corresponding sides are proportional: The lengths of the sides that connect the corresponding vertices of the triangles should have a consistent ratio. This implies that the corresponding sides are proportional to each other.
These conditions are based on the definition of similarity between two triangles. If both the corresponding angles are congruent and the corresponding sides are proportional, then the triangles zyx and wvu are considered similar (denoted by ~).

Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of $65 along with an hourly rate of $28. The plumber only charges for a whole number of hours. Anand would like to spend no more than $250, and he wonders how many hours of work he can afford. Let H represent the whole number of hours that the plumber works.1) wich inequality describes this scenario?2) What is the largest whole number of hours that anand can afford?
Let H represent the whole number of hours that the plumber works.
We were told that he's considering a plumber that charges an initial fee of $65 along with an hourly rate of $28. This means that if he hires this plumber for H hours, the expression for the total cost would be
65 + 28H
Anand would like to spend no more than $250. This means that the amount that he wnats to spend is lesser than or equal to $250.
1) If he hires the plumber, the inequality that describes this scenario would be
\(65\text{ + 28H }\leq250\)2) We would solve for H. It becomes
\(\begin{gathered} 65\text{ + 28H }\leq250 \\ 28H\text{ }\leq250\text{ - 65} \\ 28H\text{ }\leq185 \\ H\text{ }\leq\frac{185}{28} \\ H\leq6.61 \end{gathered}\)Since the number of hours must be whole numbers, then the largest whole number of hours that anand can afford is 6 hours. This is so because the next whole number is 7 hours and that would be more than he can afford

Step-by-step explanation:
There are 6 each of 7 different colored cards.
Therefore, total number of cards = 7 × 6 = 42
So the probability of each color card being chosen = 6/42 = 1/7
⇒ P(purple) = 1/7
⇒ P(green) = 1/7
So P(purple or green) = P(purple) + P(green)

Step-by-step explanation:
The way you can think about volume is that we have some cross sectional area times the height of the solid.
27.
The volume of a square based pyramid is
\(v = {s}^{2} ( \frac{h}{3} )\)
where h is the height of the pyramid
s is the side length of the square base.
S=7
h=12
\(v = {7}^{2} ( \frac{12}{3} ) = 49 \times 4 = 196\)
28. The volume of a rectangular prism
\(v = l \times w \times h\)
where l is length
w is width
h is height
\(v = 11 \times 11 \times 8 = 968\)
29.
Use the same formula in 27
\(v = 100(3) = 300\)
30.
Volume of a Cylinder is
\(v = \pi {r}^{2} h\)
where r is the radius of the circle
where h is the height
r is half of the diameter
The diameter is 22, thus the radius is 11.
\(v = {11}^{2} (8)(\pi)\)
\(v = 968\pi\)
pi is approximately 3.14
\(v = 3041.06\)
31. Volume of A Sphere
\( \frac{4}{3} \pi {r}^{3} = v\)
The radius is half of diamter, thus r=7
\( \frac{4}{3} \pi( {7}^{3} ) = 1436.76\)
When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object
with mass 4 kg, the acceleration of the object is 9 m/s². When the same force acts upon another object, its acceleration is 6 m/s². What is the mass of this
object?
Step-by-step explanation:
a = k/m or ma = k
using 4 and 9 4* 9 = k = 36
then the equation becomes:
ma = 36
using a = 6
6 * m = 36 shows m = 6 kg

The hours a week people spend answering and sending emails is normally distributed with a standard deviation of Ï = 150 minutes. How large of a sample size would you need to estimate the mean number of minutes people spend answering and sending emails with an error of 1 minutes with 99% confidence? What would be the practical problem with attempting to find this confidence interval?
Answer:
sample size n would be 149305 large
Value of n (149305) is too high, this will be the practical problem with attempting to find this confidence interval
Step-by-step explanation:
Given that;
standard deviation α = 150 min
confidence interval = 99%
since; p( -2.576 < z < 2.576) = 0.99
so z-value for 99% CI is 2.576
E = 1 minutes
Therefore
n = [(z × α) / E ]²
so we substitute
n = [(2.576 × 150) / 1 ]²
n = [ 386.4 ]²
n = 149304.96 ≈ 149305
Therefore sample size would be 149305 large
Value of n is too high, that would be the practical problem with attempting to find this confidence interval

Solve 2^x-2=8^4 but not solving for x
Without explicitly solving for x, we can conclude that the solution to the equation 2^x - 2 = 8^4 is x = 12.
To solve the equation 2^x - 2 = 8^4 without explicitly solving for x, we can simplify the equation using exponent rules and observe the relationship between the numbers.
First, let's simplify the equation:
2^x - 2 = 8^4
We know that 8 can be expressed as 2^3, so we can rewrite the equation as:
2^x - 2 = (2^3)^4
Applying the exponent rule (a^m)^n = a^(mn), we can simplify further:
2^x - 2 = 2^(34)
Simplifying the right side of the equation:
2^x - 2 = 2^12
Now, we can observe that both sides of the equation have the same base, which is 2. In order for the equation to hold true, the exponents must be equal:
x = 12
Therefore, we may deduce that the answer to the equation 2x - 2 = 84 is x = 12 without having to explicitly solve for x.

Find the 6terms of the series 247
The six terms of the series 247 are 2, 2, 2, 2, 2, and 2.
To find the six terms of a series, we need to first understand what a series is. A series is defined as the sum of the terms of a sequence. A sequence is a set of numbers in a specific order.
Therefore, a series is a sum of terms from a sequence. There are different types of series, and they have different formulas for calculating their terms.In this case, we are required to find the six terms of the series 247. Since this is a finite series, we can use a formula to calculate the nth term of a finite series.
The formula is given as follows:Tn = a + (n - 1) dWhere Tn is the nth term of the series, a is the first term of the series, n is the number of terms in the series, and d is the common difference between the terms of the series.To find the six terms of the series 247, we need to know the value of a and d. In this case, we can see that the first term of the series is 2. Therefore, a = 2.
Since this is a constant series, we can see that the common difference between the terms is 0. Therefore, d = 0.Substituting these values in the formula, we get:T1 = a + (1 - 1) dT1 = 2 + 0T1 = 2T2 = a + (2 - 1) dT2 = 2 + 0T2 = 2T3 = a + (3 - 1) dT3 = 2 + 0T3 = 2T4 = a + (4 - 1) dT4 = 2 + 0T4 = 2T5 = a + (5 - 1) dT5 = 2 + 0T5 = 2T6 = a + (6 - 1) dT6 = 2 + 0T6 = 2.
