Answer:

a = 5x

Step-by-step explanation:

The value of an in terms of x will be a = 5x.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expressions are  25x² – 35x – 18 is written as a² – 7a – 18.

The value of an in terms of x will be calculated as:-

25x² – 35x – 18

a² – 7a – 18.

Compare the first term of the two equations,

25x² = a²

a = √25x²

a = 5x

This question is incomplete, the complete question is;

Condé Nast Traveler conducts an annual survey in which readers rate their favorite cruise ship. All ships are rated on a 100-point scale, with higher values indicating better service.

A sample of 37 ships that carry fewer than 500 passengers resulted in an average rating of 85.36, and a sample of 44 ships that carry 500 or more passengers provided an average rating of 81.40.

Assume that the population standard deviation is 4.55 for ships that carry fewer than 500 passengers and 3.97 for ships that carry 500 or more passengers. What is the value of the test statistic? Round your all answers to two decimal places.

Answer:

value of the test statistic is 4.13

Step-by-step explanation:

Given the data in the question;

fewer than 500 passengers                           more than 500 passengers

n₁ = 37                                                               n₂ = 44

x'₁ = 85.36                                                         x'₂ = 81.40

s₁ = 4.55                                                            s₂ = 3.97

Now, to get the test statistics, we use the following formula;

z = (x'₁ - x'₂) / √( [tex]\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}[/tex] )

we substitute

z = ( 85.36 - 81.40 ) / √( [tex]\frac{(4.55)^2}{37} + \frac{(3.97)^2}{44}[/tex] )

z = 3.96 / √( [tex]\frac{20.7025}{37} + \frac{15.7609}{44}[/tex] )

z = 3.96 / √( 0.5595 + 0.3582 )

z = 3.96 / √0.9177

z = 3.96 / 0.957966596

z = 4.1337 ≈ 4.13

Therefore, value of the test statistic is 4.13

the answer is 4,13 of the perimeter

Answer:

10 miles per hour = 0.1862 meter per second

Step-by-step explanation:

Given

Speed in miles per hour = 10 miles per hour

As we know

1 mile = 1609.34 meters

and 1 hour  = 24*60 *60 seconds

Thus, 10 miles per hour in meter per second would be

10 * 1609.34/24*60 *60

= 0.1862 meter per second

Answer: the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23

Step-by-step explanation:

Formula for margin of error : [tex]E=\dfrac{z^*\times (Population\ standard\ deviation)}{\sqrt{Sample\ size}}[/tex]

, where z* = Critical z-value.

Given: population standard deviation = 11.5 ounces

Sample size = 20

Z value for 90% confidence level = 1.645

margin of error (E) = [tex]\dfrac{1.645\times11.5}{\sqrt{20}}[/tex]

[tex]\approx4.23[/tex]

Hence, the maximal margin of error associated with a 90% confidence interval for the true population mean turtle weight = 4.23

Answer: The answer is D) $3.35

Step-by-step explanation:

Well if we want to see the price of beef and chicken the same we should use the same variable for them making the equations

[tex]y=2.35+.25x\\y=1.75+.4x[/tex]

now let's subtract the equations for elimination

[tex]y=2.35+.25x\\-y=1.75+.4x\\\\=\\0=.6+-.15x[/tex]

now let's solve for x

[tex]0=.6-.15x\\0-.6=.6-.15x-.6\\-.6=-.15x\\\frac{-.6}{-15} =\frac{-.15x}{-.15} \\4=x[/tex]

now let's sub x into the original equations

[tex]y=2.35+.25(4)\\y=2.35+1\\y=3.35\\\\y=1.75+.4(4)\\y=1.75+1.6\\y=3.35[/tex]

Answer:

Step-by-step explanation:

3x+y+z= 4

3x+ y = 4 - z

y = 4-z-3x

We then make parallel

y-2 = 4−z−3x

y-2 = 4-2 -z-3x

y-2 = 2-z-3x

y = -z-3x+2

Answer:

Step-by-step explanation:

a) The point estimate of the population variance is 900 (rooms squared).

b) The 90% confidence interval estimate of the population variance is approximately (486, 1706) (rooms squared).

c) The 90% confidence interval estimate of the population standard deviation is approximately (22.0, 41.3) rooms.

a. The point estimate of the population variance can be calculated using the formula:

Point estimate of population variance = Sample standard deviation squared

= (30 rooms)²

= 900 rooms²

Therefore, the point estimate of the population variance is 900 (rooms squared).

b. To calculate the 90% confidence interval estimate of the population variance, we need to use the Chi-Square distribution.

The formula for the confidence interval of the population variance is:

Lower bound: (n-1)*sample variance / Chi-Square upper critical value

Upper bound: (n-1)*sample variance / Chi-Square lower critical value

Since we are interested in a 90% confidence interval, the Chi-Square critical values for the upper and lower tails with (n-1) degrees of freedom are 8.907 and 32.852, respectively.

Plugging in the values, we have:

Lower bound: (20-1)*900 / 32.852

≈ 486

Upper bound: (20-1)*900 / 8.907

≈ 1706

Therefore, the 90% confidence interval estimate of the population variance is approximately (486, 1706) (rooms squared).

c. To calculate the 90% confidence interval estimate of the population standard deviation, we take the square root of the lower and upper bounds of the confidence interval for the variance.

Square root of the lower bound: √486

≈ 22.0

Square root of the upper bound: √1706

≈ 41.3

Therefore, the 90% confidence interval estimate of the population standard deviation is approximately (22.0, 41.3) rooms.
