Area of a square is 64 sq cm.Its perimeter is _______

Answer:

m=2

Step-by-step explanation:

Answer:

\(m=2\)

Step-by-step explanation:

\(3\left(m+5\right)=3+3\left(2m+2\right)\)

Expand:

\(3m+3\times5=3+3\times2m+3\times2\)

\(3m+15=3+6m+6\)

\(3m+15=6m+9\)

Subtract 15 from both sides:

\(3m+15-15=6m+9-15\)

\(3m=6m-6\)

Subtract 6m from both sides:

\(3m-6m=6m-6-6m\)

\(-3m=-6\)

Divide both sides by -3:

\(\frac{-3m}{-3}=\frac{-6}{-3}\)

\(m=2\)

Using the standard deviation value of these interarrival times, the coefficient of variation is 0.012.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

The standard deviation to mean ratio, or coefficient of variation (CV), illustrates the degree of variability in proportion to the population mean. The dispersion increases with increasing CV.

Formula is given by:

\(CV = \frac {\sigma}{\mu}\)

\(\sigma = 0.02\)

Mean for the time of 0.02 sec is = 79 * 0.02

=1.58

CV= 0.02/1.58

Answer:

y = 9 - 2x / 3

Step-by-step explanation:

Refer the attached picture

We have 95% confidence in our interval, instead of 100%.because we need to account for the fact that a) the sample may not be truly random.

Strictly speaking, a 95% confidence interval means that if we were to take 100 different samples and calculate a 95% confidence interval for each sample, then approximately 95 of the 100 confidence intervals will contain the true mean (μ). In practice, however, we take one random sample and generate one confidence interval, which may or may not contain the true mean. The observed interval may overestimate or underestimate μ. Consequently, the 95% CI is the likely range of the true, unknown parameter. A confidence interval does not reflect the variability in the unknown parameter. Rather, it reflects the amount of random error in the sample and provides a range of values ​​that are likely to include the unknown parameter. Another way of thinking about a confidence interval is that it is a range of possible values ​​of a parameter (defined as a point estimate + margin of error) with a specified confidence level (which is similar to a probability).

2x - 2 ≤ 6 or 2x - 2 ≥ -6

2x - 2 ≤ 6

2x ≤ 8

x ≤ 4

2x - 2 ≥ -6

Answer:

x = 9 hope i helped and sorry if I'm wrong :)

Answer: x = -2 and y = -5

We are given two system of equations

-6x - 2y = 22 ---------------- equation 1

-12x + 10y = - 26------------- equation 2

These two system of equations can be solve simultaneously using elimination method

Before we can apply elimination method, we need to make one of the variables equal in both equations

Let us eliminate x

To make the co -efficient of x equal in both equations, Multiply equation 1 by 2 and equation 2 by 1

-6x - 2y = 22 * 2

-12x + 10y = -26 * 1

This becomes

-6x * 2 - 2y* 2 = 22*2

-12x*1 + 10y *1 = -26 * 1

-12x - 4y = 44------------------- equation 3

-12x + 10y = -26 --------------- equation 4

To eliminate x, substract equation 4 from equation 3

-12x - (-12x) - 4y - (10y) = 44 - (-26)

-12x + 12x -4y -10y = 44 + 26

0 - 14y = 70

-14y = 70

Divide both sides by -14

To find x, substitute the value of y = -5 into equation 1

-6x - 2y = 22

-6x - 2(-5) = 22

-6x + 10 = 22

-6x = 22 - 10

-6x = 12

Divide both sides by -6

Hence, x = -2, and y = -5 : (-2, -5)

What is total cost function?

Total cost function is the sum of the fixed charge, which is fixed cost to the person paying the contractor when the contractor visits the site and charge per hour multiplied by the number of hours spent working

TC=a+bX

TC=total cost=$555

a=fixed charged=$55

b=charge per hour=variable element of contractor's pay=$25

X=number of hours spent working=unknown

The phenotype of an organism can provide clues about its genotype for a particular trait. To determine if an organism is homozygous or heterozygous for a dominant trait like tallness, test crossing can be performed. If the organism is heterozygous, approximately 75% of the offspring will exhibit the dominant phenotype.

To determine whether an organism is homozygous or heterozygous for a dominant trait like tallness, a test cross can be conducted. A test cross involves crossing the organism in question with an organism that is homozygous recessive for the trait. If the organism being tested is homozygous dominant, then all the offspring resulting from the test cross will exhibit the dominant phenotype. On the other hand, if the organism being tested is heterozygous, approximately 50% of the offspring will show the dominant phenotype, while the other 50% will show the recessive phenotype.

Based on the explanation above, the correct answer is c. 75%. If an organism is heterozygous for a dominant trait, approximately 75% of the offspring resulting from a test cross will exhibit the dominant phenotype, while the remaining 25% will show the recessive phenotype.

3.60X10^-12 is equal to 0.360X10^-11 (move decimal one place left)

Step-by-step explanation:

Now you can add 3.60X10^-11 and 0.360X10^-11:

3.60X10^-11 + 0.360X10^-11 = 3.96X10^-11

You're really just adding 3.60 to 0.36 since the "X10^-11" is the same for both.

With 90% confidence, the population mean number of visits per week is between the lower and upper bounds of the confidence interval.

To compute the confidence interval, we can use the t-distribution since the sample size is less than 30 and the population standard deviation is unknown.

a. To compute the confidence interval, we need to determine the margin of error and then calculate the lower and upper bounds.

The margin of error (ME) is given by the formula:

ME = t * (s / sqrt(n))

where t is the critical value for the desired confidence level, s is the sample standard deviation, and n is the sample size.

First, we need to find the critical value for a 90% confidence level. Since we have 234 members in the sample, we have n = 234 - 1 = 233 degrees of freedom. Using a t-table or calculator, the critical value for a 90% confidence level and 233 degrees of freedom is approximately 1.652.

Substituting the values into the margin of error formula:

ME = 1.652 * (2.7 / sqrt(234))

Next, we can calculate the lower and upper bounds of the confidence interval:

Lower bound = sample mean - ME

Upper bound = sample mean + ME

Lower bound = 2.2 - ME

Upper bound = 2.2 + ME

b. With 90% confidence, the population mean number of visits per week is between the lower and upper bounds of the confidence interval.

Lower bound = 2.2 - (1.652 * (2.7 / sqrt(234)))

Upper bound = 2.2 + (1.652 * (2.7 / sqrt(234)))

The installing hardwood floors over a 1/2 inch thick plywood subfloor, it is recommended to use 2-inch L-shaped cleats with a flooring nailer. This will ensure that the hardwood planks are securely fastened to the subfloor and reduce the likelihood of squeaking or loose planks in the future.

When installing hardwood floors over a plywood subfloor, it is important to use the appropriate length of L-shaped cleats. The L-shaped cleats are nails used by a flooring nailer to attach the hardwood planks to the subfloor. In this case, the subfloor is a 1/2 inch thick plywood, while the hardwood planks are 3/4 inch thick.
The recommended length of L-shaped cleats to use when installing hardwood floors over a 1/2 inch thick plywood subfloor is 2 inches. This is because the 2-inch cleats will provide enough length to penetrate the subfloor and securely fasten the hardwood planks to the subfloor. Using shorter cleats may not provide enough grip and the hardwood floors may eventually become loose.
The flooring nailer shoots the L-shaped cleats in at a 45-degree angle, which helps to ensure that the cleats go in straight and do not damage the surface of the hardwood planks. It is important to use the appropriate length of cleats to avoid damaging the subfloor or the hardwood planks during installation.
In summary, when installing hardwood floors over a 1/2 inch thick plywood subfloor, it is recommended to use 2-inch L-shaped cleats with a flooring nailer. This will ensure that the hardwood planks are securely fastened to the subfloor and reduce the likelihood of squeaking or loose planks in the future.

Answer: The answer to this math question about solving for the value of k with the given full of the angles is k = 6.

Step-by-step explanation: As always to remember, all of the forming angles to a straight line with a sum of 180 degrees, so anyways, here are 6 steps in order to solve for the value of k:

Step 1. First, let's find the measures of the value of all 3 angles, the measures of all 3 angles are, 8°, 90°, and 40° that looks in the equation form like this: \(7k + 8 + 90 + 40 = 180.\)

Step 2. Next, after finding the measures of the value of all 3 angles, it's time to add all 3 angles up together that looks in the equation form like this: \(7k + 138 = 180.\)

Step 3. Then, let's move positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side that looks in the equation form like this: \(7k = 180 - 138.\)

Step 4. In addition to that, after moving positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side, it's time to subtract 138 degrees and 180 degrees that looks in the equation form like this: \(7k = 42.\)

Step 5. Now last but not least is finally, after subtracting 138 degrees and 180 degrees, it's time to divide the both sides by 7 that looks in the equation form like this: \(\frac{7k}{7}=\frac{42}{7}.\)

Step 6. Hence the value of k is 6.

I hope that my full given answer with my full given step-by-step explanation is very helpful to your own math question about solving for the value of k with the given full of the angles, please mark me as Brainliest, take care, always be safe, and have a great rest of the day and a great weekend! :D
