Given a random sample of size 24 from a normal distribution, find k such that (a) p(−2.069
The graph of the normal distribution of the random sample size of 24 will have the shape of a bell curve.
The value of k such that P(-2.069 < T < k) = 0.965 is 2.5
How to determine the value of k?The sample size is given as:
n = 24
This means that the degrees of freedom is:
df = n - 1
df = 24 - 1
df = 23
The probability is given as:
P(-2.069 < T < k) = 0.965
This can be rewritten as:
P(T>-2.069) - P(T>k) = 0.965
The value of P(T>-2.069) at a degrees of freedom of 23 and [tex]\alpha[/tex] = 0.025 is 0.975
So, we have:
0.975 - P(T>k) = 0.965
Collect like terms
P(T>k) = 0.975 - 0.965
Evaluate the difference
P(T>k) = 0.01
The value of k that makes P(T>k) = 0.01 is 2.5.
So, we have:
k = 2.5
Hence, the value of k is 2.5

Nate’s ice-cream cone has a diameter of 4 cm and a height of 14 cm. what is the approximate volume of the ice-cream cone?
Answer: 58.643 cm^3
Explanation:
Volume of a cone = (1/3) * π * r^2 * h
Half of the diameter is the radius, so r = 2 and h = 14.
Plug in: V = (1/3) * π * 2^2 * 14 = 58.643 cm^3 :)
A conservation agency tracks the sea turtle population by counting the number of nesting sites where the turtles lay their eggs. The table shows the numbers of nesting sites for several years since 2001. The data can be modeled by an exponential function
Based on the number of years, and the number of nesting sites, the exponential function that best models the data is B. n(x) = 46,797(0.93)ˣ.
What function best models the data?You can find the correct function by testing out the options with the given x value to see if it correctly predicts the number of nesting sites.
Function n(x) = 25,956.80(1.08)ˣ
Assuming x is 3:
= 25,956.80(1.08)³
= 32,698 sites
This function does not predict the correct number of sites which is 40,513.
Function n(x) = 46,797(0.93)ˣ
Assuming x is 3:
= 46,797(0.93)³
= 37,438 sites
This is closer to the predicted number of 40,513 sites with some discrepancy.

The kinetic energy of the two-block system with the given masses before the collision is determined as ³/₂Mvs².
Kinetic energy of the blocks before collisionThe kinetic energy of the blocks before the collision is calculated as follows;
For a negligible friction effect, the kinetic energy of the two - block system after the collision is equal to the kinetic energy before the collision.

This is expressed as;

Answer:
For long-lived assets that have been in use for more than one accounting period, Depreciation Expense on the debit. Accumulated Depreciation on the credit.
Explanation:
Therefore, the entry that was made by the accountant, assets and stockholders' equity will be decreased.
For long-lived assets that have been in use for more than one accounting period, Depreciation Expense on the income statement will be less than Accumulated Depreciation on the balanced sheet. The correct option is 2.
Depreciation expense is shown on the Income Statement for long-lived assets that have been in use for more than one accounting period, while accumulated depreciation is reported on the Balance Sheet.
The part of an asset's cost that is spread out as an expense over its useful life is represented by depreciation expense.
It is deducted from the company's net income for the accounting period and reported as an operational expense on the income statement.
Thus, depreciation expense is shown as an expense on the income statement, which lowers net income, while accumulated depreciation is shown as an asset's carrying value on the balance sheet. The correct option is 2.
