in an experiment to learn whether substance m can help restore memory, the brains of 20 rats were treated to damage their memories. first, the rats were trained to run a maze. after a day, 10 rats (determined at random) were given substance m and 7 of them succeeded in the maze. only 2 of the 10 control rats were successful. the two-sample z test for the difference in the true proportions. Gives z= 2.25, P< 0.02

Answers

The z-value obtained from the test was 2.25, and the p-value was less than 0.02.

What is probability ?

Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.

Based on the experiment described, a two-sample z-test for the difference in proportions was conducted to determine if there is a significant difference between the proportion of rats that succeeded in the maze after being given substance m and the proportion of rats in the control group that succeeded in the maze.

This suggests that the difference in proportions between the two groups is statistically significant at the 0.05 level of significance (since the p-value is less than 0.05).

In other words, the results of the experiment suggest that substance m may be effective in helping to restore memory, as a greater proportion of rats in the substance m group succeeded in the maze compared to the control group. However, it's important to note that further experiments and analyses would be necessary to confirm these findings and determine the extent of the effect of substance m on memory restoration.

Therefore, The z-value obtained from the test was 2.25, and the p-value was less than 0.02.

Answer:

m∠STU = 42°

Step-by-step explanation:

We need a relation between angle RTS and angle RTU. We are told that RS is congruent to RU, and we know RT is congruent to itself, so we can claim right triangles RUT and RST are congruent by the HL postulate.

Corresponding angles in congruent triangles are congruent. This means ...

angle RTS = angle RTU

5w -69° = w +3°

4w = 72° . . . . . . . . . add 69°-w to both sides

w = 18°

Then angle RTU is w+3° = 18° +3° = 21°. The angle we're to find is angle STU, which is double this measure: angle STU = angle RTS + angle RTU = 21° +21°.

m∠STU = 42°

A borrower wants to take a loan with a maximum effective monthly rate of 1%. What is the maximum APR with quarterly compounding that the borrower will accept from a lender?

Answers

The maximum APR with quarterly compounding that the borrower will accept from a lender is 16.132%.

How to calculate APR?

To convert the maximum effective monthly rate of 1% into an APR with quarterly compounding, we can use the formula:

$APR = [(1 + \dfrac{r}{n})^n - 1] \times 4$

Where r is the effective monthly rate and n is the number of compounding periods per year. In this case, we want to find the maximum APR with quarterly compounding that the borrower will accept, so we can substitute r = 1% and n = 3:

$APR = ((1 + \dfrac{0.01}{3})^3 - 1) \times 4$

APR = (1.0100333³ - 1) x 4

APR = 0.04033 x 4

APR = 0.16132 or 16.132%

Therefore, the maximum APR with quarterly compounding that the borrower will accept from a lender is 16.132%.

Question
A card is drawn from a standard deck of 52 cards and then placed back into the deck. Find the probability that a red card is
drawn at least once by the third draw. Round your answer to two decimal places.
Provide your answer below:

Answers

The probability that a red card is drawn at least once by the third draw is 0.88.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Let, a card is drawn from a standard deck of 52 cards and then placed back into the deck.

In a standard 52 card deck the red cards are 26.

So,

P(red) = n(red cards) / n(total cards)

= 26 / 52

P(red) = 0.50

Now, X ≈ Bin (n = 3, P = 0.50)

P(X = x) = (n x) p^x (1 - p)^n-x

(n x) = $\frac{n!}{x!(n-x)!}$

P(X ≥ 1) = 1 - P(X < 1)

= 1 - P(X = 0)

= 1- (3 0)(0.5)^0(0.5)^3

= 1 - 0.125

= 0.875

P(X ≥ 1) = 0.88

Hence, the probability that a red card is drawn at least once by the third draw is 0.88.

What is simple interest?

Simple interest is a method of calculating the interest charge. The interest can be calculated as the product of principal amount, rate and time peroid.

We are given that Phyllis invested $11,000, a portion earning a simple interest rate of 2 1/2% per year and the rest earning a rate of 2% per year.

Given the following :

Amount invested = $11,000

A portion earns 2 and 1/2 % interest per year

The rest earns a rate of 2% per year

The Total Interst earned after a year = $255

Amount invested at each rate;

Let amount invested at 2 1/2% = a

Amount invested at 2% is; 11,000 - a

Simple interest = principal x rate x time

First investment :

a x 5/2% x 1

Second :

(11000 - a) x 2%

Firat investment + second = $225

a x 0.025 + (11000 - a) x 0.02 = 225

0.025a + 220 - 0.02a = 225

0.005a = 225 - 220

0.005a = 5

a = 5 / 0.005

a = 1000

Amount in first investment = 1000

The value of x is 6.

What is system of linear equations?

A collection of one or more linear equations involving the same variables is known as a system of linear equations in mathematics. For instance, the system of three equations 3x + 2y - z = 1, 2x - 2y + 4z = -2, -x + y - z = 0 has the three variables x, y, and z.

A collection of one or more linear equations involving the same variables is known as a system of linear equations (or linear system) in mathematics.

Graphically, a system of linear equations that has no solution indicates two parallel lines-that is, two lines that have the same slope but different y-intercepts.

To have the same slope, the x-and y-coefficient must be the same.

To get from -2/3 to -8 you multiply by 12, so multiply -1/2x by 12 as well to yield 6x.

Because the other x-coefficient is a, it must be that a = 6 and (D) is correct.

Note that, even though it is more work, you could also write each equation in slope-intercept form and set the slopes equal to each other to solve for a.

Hence, the value of x is 6.

To solve the equation $\sf 5(n - \frac{1}{10}) = \frac{1}{2} \\$ for $\sf n \\$, we can follow these steps:

Step 1: Distribute the 5 on the left side:

$\sf 5n - \frac{1}{2} = \frac{1}{2} \\$

Step 2: Add $\sf \frac{1}{2} \\$ to both sides of the equation:

$\sf 5n = \frac{1}{2} + \frac{1}{2} \\$

$\sf 5n = 1 \\$

Step 3: Divide both sides of the equation by 5 to isolate $\sf n \\$:

$\sf \frac{5n}{5} = \frac{1}{5} \\$

$\sf n = \frac{1}{5} \\$

Therefore, the solution to the equation $\sf 5(n - \frac{1}{10})\ = \frac{1}{2} \\$ is $\sf n = \frac{1}{5} \\$, which corresponds to option (d).

What part of an hour passes from 3:12 p.m. to 5:30 p.m.?

Answers

Answer:

2.3 hours

Step-by-step explanation:

From 3:12 pm to 4:12 pm, one hour passes.

From 4:12 pm to 5:12 pm, another hour passes.

From 5:12 pm to 5:30 pm, there are 18 minutes that pass.

Therefore, the total time elapsed is 2 hours and 18 minutes out of 60 minutes in an hour.

To convert this to a fraction, we can write:

2 hours + 18 minutes = 2 + 18/60 hours = 2.3 hours

Answers

The vertex of the given equation is (0,12) and (1, -10). The value of y-intercept will be -12.

Given equation :

y=(x−2)2−8

y = 2x - 4 - 8

= 2x - 12

The final equation is y = 2x - 12.

Compare this equation with slope and y-intercept formula :

y = mx+c

So that c = -12

The value of y-intercept according to the solution is -12.

To find the vertex. Let's assume x=0; Substitute in the equation

y = 2(0) -12

y = -12

The first vertex will be (0, -12)

If x = 1; y = 2(1) -12

y = -10

Then the second vertex will be (1, -10).

Hence, the vertex of the given equation is (0,12) and (1, -10). The value of y-intercept will be -12.

What is a perimeter?

Whether it be a two-dimensional shape or a one-dimensional length, a perimeter is a closed path that contains, surrounds, or delineates it. A circle's or an ellipse's circumference is its furthest boundary. There are various useful situations where knowing the perimeter is useful.

The whole length of a shape's boundary is referred to in geometry as the perimeter of the shape. By multiplying the lengths of all the sides and edges that surround an object, the perimeter may be calculated. It is measured in measures of length that are linear, such as centimeters, meters, inches, or feet.

As all sides in a square are equal and for calculating the perimeter this side will be multiplied by 4.

Perimeter = 563 x 4 = 2252 yards.

rate, to the nearest hundredth of a percent, would be required in order
for Arianys to end up with $20,000?

Answers

The compound interest rate of the investment is 1.10%

How to determine the compound interest rate?

The given parameters about the compound interest are

Principal, P = $11,000

Amount, A = $20,000

Time, t = 9

Number of times, n = 12 i.e. monthly interest

To calculate the amount, we have:

A = P(1 + R/n)^nt

Substitute the known values in the above equation, so, we have the following representation

20000 = 11000 * (1 + r/12)^(12 * 9)

This gives

1.82 = (1 + r/12)^108

Take the 108th root of both sides

1 + r/2 = 1.0055

Subtract 1 from both sides

r/2 = 0.0055

Multiply by 2

r = 0.011

Express as percentage

r = 1.10%

Hence, the value of the interest rate is 1.10%

Answer:

x+y=70; 8.50x+12.50y=10.56(70)36 pounds Antigua34 pounds Rift

Step-by-step explanation:

At the insistence of the problem author, we will let x represent pounds of Antigua coffee and y represent pounds of Rift coffee. Then we have ...

x + y = 70

8.50x +12.50y = 10.56(70) . . . . . total cost of the mix

We like to use the variable to represent the high-cost contributor. Here, that is y, so we'll substitute for x:

x = 70-y

8.50(70 -y) +12.50y = 10.56(70)

595 +4y = 739.2 . . . . . . . . . . . . . . simplify

4y = 144.2 . . . . . . . . . . . subtract 595

y = 36.05 . . . . . . . divide by 4

x = 70 -36.05 = 33.95

About 36 pounds of Rift Valley coffee and 34 pounds of Gualtemala Antigua coffee must be mixed.

_____

By letting the variable in our equation 8.50(70 -y) +12.50y = 10.56(70) represent the high-cost coffee, we ensure that the simplified equation will have a positive coefficient for the variable. This means we don't have to mess with negative numbers, so eliminating a common source of math errors.

The problem requirement that we use x for the low-cost contributor meant we introduced an extra equation that would not have been needed.
