Answer:

its A

Step-by-step explanation:

on edge  2021

The equation of l1 in the form y = mx + c is:

y = 2x - 3.

We can find the slope of the line passing through points (3,3) and (5,7) using the slope formula:

slope m = (y2 - y1) / (x2 - x1)

= (7 - 3) / (5 - 3)

= 2

Now we can use the point-slope form of the equation of a line to find the equation of l1:

y - y1 = m(x - x1)

y - 3 = 2(x - 3)

Simplifying this equation, we get:

y - 3 = 2x - 6

y = 2x - 3

Therefore, the equation of l1 in the form y = mx + c is:

y = 2x - 3.

If a bank receives a new deposit of $15,000, the bank can lend out $13,785.

The required reserve ratio is the fraction of deposits that banks must hold as reserves. If the current required reserve ratio is 8.1% and a bank receives a new deposit of $15,000, they can lend out $13,785.

The bank can lend out the amount equal to the deposit minus the required reserve amount. In this case, the new deposit is $15,000 and the required reserve ratio is 8.1%, so the calculation is as follows:

Required reserve amount = Deposit × Required reserve ratio

Required reserve amount = $15,000 × 0.081

Required reserve amount = $1,215

The bank must hold $1,215 as required reserves and can lend out the remaining amount:Amount available for lending = Deposit − Required reserve amount

Amount available for lending = $15,000 − $1,215

Amount available for lending = $13,785

Step-by-step explanation:

No x intercept means it can't touch the x axis y=x^{2}+1 does the trick since it moves the whole thing up one unit

The exact growth rate (r) for the exponential model or the slope (m) and y-intercept (b) for the linear model. More data points or additional information about the population growth pattern would be needed to construct a precise model for P(t).

To find a model for P(t), representing the U.S. population in 1960, we need to determine the growth or decay rate over time. Without additional information or assumptions about the population growth, we cannot provide an exact model. However, we can explore two common models: exponential growth and linear growth.

1. Exponential Growth Model:

If we assume that the U.S. population experienced exponential growth, we can use the formula P(t) = P₀ * e^(rt), where P₀ represents the initial population, r is the growth rate, t is the time in years, and e is the base of the natural logarithm (approximately 2.71828).

Using the given information that the U.S. population in 1960 was 181 million, we can write the equation as follows:

181,000,000 = P₀ * e^(r * 1960)

2. Linear Growth Model:

Alternatively, if we assume that the U.S. population grew linearly, we can use the formula P(t) = mt + b, where m is the slope (rate of change) and b is the y-intercept.

Using the given information, we can form an equation as follows:

181,000,000 = m * 1960 + b

Without further information or data points, we cannot determine the exact growth rate (r) for the exponential model or the slope (m) and y-intercept (b) for the linear model. More data points or additional information about the population growth pattern would be needed to construct a precise model for P(t).

we would need a sample size of at least 502 for the approximate probability of the random interval (Y1/n - Y2/n) ‡ 0.05 covering pi - p2 to be at least 0.80.

To compute n, we can use the formula:
n = ((zα/2)^2 * 2p*(1-p*)) / (ε^2)
Where zα/2 is the z-score associated with a confidence level of 1-α, p* is the probability of success for a binomial distribution, and ε is the margin of error.
Since we are given that the approximate probability of the random interval (Y1/n - Y2/n) ‡ 0.05 covering pi - p2 is at least 0.80, we can set α = 0.20 to find the corresponding z-score of 1.28.
Using p* = 1/2 as an upper bound for both P1 and P2, we can calculate the margin of error as:
ε = zα/2 * sqrt((p*(1-p*)) / n)
Plugging in the values, we get:
0.05 = 1.28 * sqrt((0.25) / n)
Solving for n, we get:
n = 501.76
Therefore, we would need a sample size of at least 502 for the approximate probability of the random interval (Y1/n - Y2/n) ‡ 0.05 covering pi - p2 to be at least 0.80.

There are 6 pairwise comparisons that need to be made in order to gain a complete understanding of which treatment effects differ significantly from others.

In order to determine which treatment effects differ significantly from others, we need to make pairwise comparisons between all possible pairs of treatment groups. Let's consider an example with four treatment groups labeled A, B, C, and D.

To determine which treatment effects differ significantly from others, we need to compare the mean scores of each treatment group with the mean scores of every other treatment group. This means we need to make the following pairwise comparisons:

A vs B

A vs C

A vs D

B vs C

B vs D

C vs D

Therefore, there are 6 pairwise comparisons that need to be made in order to gain a complete understanding of which treatment effects differ significantly from others.

It's worth noting that when making multiple pairwise comparisons, there is an increased risk of making a Type I error (i.e., rejecting the null hypothesis when it is actually true) due to the multiple testing problem. To control for this, researchers may choose to adjust the significance level or use methods such as the Bonferroni correction to adjust the p-values of the individual tests.

As per the given situation, D. these apply only to the population of those students who drive to the college.

The study's 95% confidence interval only pertains to the group of students who drive to the institution and were present near the parking lot when the survey was conducted. Since the sample might not be entirely representative of the total population of interest, it may not necessarily apply to all students who drive to college.

The purpose of the poll was to learn whether or not college students supported the construction of a multi-level parking garage that would add 425 new spaces to the campus. The students also computed a 95% confidence interval based on the survey results to determine the range of expected values for the genuine proportion of students who favour the construction of the new parking structure.

The correct answer is D. After the loop, the last row of matrix is 0, 0, 0, 0, 10.

This is because the code initializes a 5x5 matrix with all elements set to 0. Then, the for loop iterates over the length of the last row (which is 5), and sets the values in the last row to 10. However, the loop also has a semicolon immediately after the condition, which effectively terminates the loop before it even starts executing the loop body.

Therefore, only the initialization statement (which does nothing) and the semicolon are executed, leaving the rest of the matrix unchanged except for the last element in the last row, which is set to 10.

In computer programming, an initialization statement is a statement used to set an initial value to a variable or constant when it is declared. This is typically done to ensure that the variable or constant starts with a known and expected value, and to avoid any unpredictable behavior that may result from uninitialized data.

Therefore, the value of the expression for x = 5 is 23 when the expression is 2*(x-2)² +5.

An expression is a mathematical phrase that combines numbers, variables, and operations. Expressions can be simple or complex, and they can represent quantities or relationships between quantities. Expressions can be evaluated by substituting values for the variables, simplifying the operations, and obtaining a numerical result. Some expressions can be simplified or factorized using algebraic rules and techniques.

Here,

To evaluate the expression for x=5, we substitute 5 for x and simplify:

=2(x - 2)² + 5

= 2(5 - 2)² + 5 (substitute x = 5)

= 2(3)² + 5 (simplify inside the parentheses)

= 2(9) + 5 (square 3)

The decimal fraction that represents the given fraction is: 0.36.

To convert the figure from the given form to the decimal fraction, you can choose to use the long division format or simply divide it with the common factors. Between, 9 and 25, there is no common factor, so the best method to use here will be long division. Thus, we can proceed as follows:

1. 25 divided by 9

This cannot go so, we put a zero and a decimal point as follows: 0.

Then we add 0 to 90

2. Now, 25 divided by 90 gives 3 remainders 15. We add 3 to the decimal: 0.3

3. 90 minus 75 is 15. we add a 0 to this and divide 150 by 25 to get 6. This is added to the decimal to give a final result of 0.36.

Answer:

The cup holds 26.2 in3 more ice cream than the cone.

Step-by-step explanation:

1. Let's find the volume of ice cream that the cone holds, this way:

Volume = π * r² * h/3

Replacing with the real values, we have:

Volume = 3.14 * 2.5² * 5/3

Volume =32.7 inches³

2. Let's find the volume of ice cream that the cup holds, this way:

Volume = π * r² * h

Diameter = 5 inches ⇒ Radius = 2.5 inches

Replacing with the real values, we have:

Volume = 3.14 * 2.5² * 3

Volume =58.9 inches³

3. Let's find the difference, this way:

Volume of the cup - volume of the cone = 58.9 - 32.7 = 26.2 inches³

The cup holds 26.2 in³  more ice cream than the cone.
