Step-by-step explanation:

In performing hypothesis tests about the population mean, a t-test can be used if the population standard deviation is not known and the sample is random.

The conditions of a random sample and unknown population standard deviation are necessary for the t-test to be applicable.

When conducting hypothesis tests about the population mean, if the population standard deviation is unknown, the t-test is appropriate to use. The t-test is specifically designed for situations where the population standard deviation is not known and must be estimated from the sample. By using the sample data, the t-test calculates a test statistic called the t-value, which is used to determine the statistical significance of the mean difference.

However, it is important to note that in addition to the unknown population standard deviation, the sample must also be random for the t-test to be valid. Random sampling helps ensure that the sample is representative of the population, which is crucial for making accurate inferences. Therefore, options (b) "the sample is random" and (d) "the population is normally distributed" are the correct conditions for using a t-test when the population standard deviation is unknown.

Answer:

Step-by-step explanation:

First of all you have to put the zeros into factor form.

y1 = (x + 2)(x - 5)

Notice that the x changes sigh. You say that the zeros are -2 and  5. To get y1 to go to zero, you must make x the opposite sign of what you are given.

Now you have to expand the factored form to get the standard form

y = x^2 + 2x - 5x - 10

y = x^2 - 3x - 10

That's not the right answer.

f(0) = 30 but you have - 10 at the end so you have to multiply the factored form by - 3

-3(f(x)) = -3(x + 2)(x - 5)

-3(f(x)) = -3(x^2 - 3x - 10)

f(x) = -3x^2 + 9x + 30    

f(0) = -3(0)^2 + 9(0) + 30

f(0) = 30

The quadratic still has roots of (x +2)(x - 5) but that 3 makes the y intercept = 30.

Answer:

0.011 or 1/90

Step-by-step explanation:

Since the order of the performances is determined at random the probability of each squad is constant that 1/10

The probability of your squad is 1/10

Given that the first selected was yours (1/10) nine squads are left . Therefore the probability of your friends squad is 1/9.

Hence  the probability that your squad performs first and your friend's squad performs second is (1/10 * 1/9) 1/90 or 0.011

The total cost incurred per month for renting apartment 3 is $2,150 and the apartment with the highest total cost per month is apartment 4, so the answer is 4.

To find the total cost incurred per month if Ryan rents apartment 3, we need to calculate the monthly rent and the commuting cost:

Monthly rent for apartment 3 = $2,000

Commuting cost for apartment 3 = 10 hours/month × $15/hour = $150

Total cost incurred per month for apartment 3 = $2,000 + $150 = $2,150

Therefore, the answer is C) $2,150.

To find the apartment that has the highest total cost per month, we need to calculate the total cost for each apartment by adding the monthly rent and commuting cost:

Apartment 1: $1,500 + 40 hours/month × $15/hour = $2,100

Apartment 2: $1,750 + 20 hours/month × $15/hour = $2,050

Apartment 3: $2,000 + 10 hours/month × $15/hour = $2,150

Apartment 4: $2,210 + 4 hours/month × $15/hour = $2,270

Apartment 5: $2,250 + 1 hour/month × $15/hour = $2,265

Therefore, the apartment with the highest total cost per month is apartment 4, so the answer is C) 4.

The required value of the function is 2

In the case of a function from one set to the other, each element of X receives exactly one element of Y.

The given function is of the form :

g(x) = - x² - 7

Now let us find the required values.

g (-3) = - (-3)² - 7 = 2

g (-2) = - (-2)² - 7 = -3

g (1 ) = - ( -1 )² - 7 = -6

Hence the required value of the function is 2 at x = -3 .

In an inorder traversal of a binary search tree, the keys are visited in ascending order. Starting from the left subtree, the left child is visited first, followed by the root, and then the right child. This process is then repeated for the right subtree. So, the keys are visited in ascending order from the smallest to the largest value in the tree. In the given binary search tree, the sequence of keys visited in an inorder traversal is 12, 23, 25, 30, 37, 40, 45, 50, 60, 75, 80, 88.

The exact slope of the tangent line to the parametric curve { x = 6cos (t) y=2sin(t) at the point where t = pi/3 is -2√3.

The slope of a tangent line to a parametric curve is equal to the derivative of the y coordinate with respect to the x coordinate.

So, we first need to find the derivatives of x and y. The derivative of x with respect to t is -6sin(t) and the derivative of y with respect to t is 2cos(t).

Substituting t = pi/3 into the derivatives, we get -6sin(pi/3) for x and 2cos(pi/3) for y.  Simplifying, we get -3√3 for x and 1 for y. Thus, the slope of the tangent line to the parametric curve at t = pi/3 is m = y'/x' = -2√3.

Slope of the line 'm' = 5

Step-by-step explanation:

Step(i):-

Given that the straight line

               y = m x + c

given that the straight line

              y = 5x +20

comparing   y = m x + c

Slope of the line 'm' = 5

We are given the following details

To find the radius, we will make the radius, the subject of the formula from the equation:

Substituting the values, we will obtain

The radius of the cylinder 8.00

Answer:

Domain is 3 <x>_-2

Range is 6 <x>_-3 (the lines are supposed to be under the >. it means equal to)

Step-by-step explanation:

First look on the x-axis, is goes from 3 to -2. now look at the colored in dot. that means more than or equal to. So the sign of -2 is x >_ -2. put the 3 on the other side. It stops at three so the sign is > 3. so 3<x>_ -2

Do the same with the y-axis except look up and down instead of left and right. so the numbers are 6 and -3. Use the same method above. this is set builder notation.

Answer:

\(\boxed {\boxed {\sf v= 2463.0 \ yd^3}}\)

Step-by-step explanation:

The volume of a cylinder is found using the following formula:

\(v= \pi r^2h\)

The height of the cylinder is 16 yards and the radius is 7 yards. Let's use the pi button on a calculator for pi. Substitute these values into the formula.

\(v= \pi* (7 \ yd)^2 * 16 \ yd\)

Solve the exponent.

\(v= \pi * 49 \ yd^2 *16 \ yd\)

Multiply the three numbers together.

\(v= \pi *784 \ yd^3\\v=2463.00864041 \ yd ^3\)

Round to the nearest tenth.

The 0 in the hundredth place tells us to leave the 0 in the tenth place.

\(v= 2463.0 \ yd^3\)

The volume of the cylinder is 2463.0 cubic yards.

We need to use 7 terms to estimate the value of ln(1.4) to within 0.0001.

A Maclaurin series is a function that is used to estimate the values functions, evaluate the sum, or determine the value of the anti-derivative of a function.

We have:

f(x)=ln(1+x)

Expansion of In(1+x) up to seven terms is:

In(1+x) = x - x^2/2 + x^3/3 - x^4/4 + x^5/5 - x^6/6+ x^7/7

Where it is known that -1 <= x <= 1

Put x=0.4 in the above series:

ln(1.4) = 0.4 - 0.4^2/2 + 0.4^3/3 - 0.4^4/4 + 0.4^5/5 - 0.4^6/6+ 0.4^7/7

We get:

ln(1+4) = 0.3365333

Therefore,  we need 7 terms to estimate the value of ln 1.4 to within 0.0001.

Answer:

v = -1

Step-by-step explanation:

First, you will need to solve it step-by-step:

(4v − 9)(1 + v) = 0

Next, you need to simplify both sides of the equation:

4v(2) − 5v − 9 = 0

Now, factor the left side of equation:

(4v − 9)(v + 1) = 0

The last thing you need to do is to set all of the factors to equal to zero:

4v − 9 = 0 or v + 1 = 0

So, that means that you answer:

v=9/4 or in your case, v = −1

2.Find out the amount that was actually spent

Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.

(4 * 30) + 30

= 120 + 30

= 150
