A high school student named David Merrell did a study of how music affects the ability of rats to run a maze. He trained 71 rats to run a maze. Next he randomly divided the rats to three groups. Each group had 23 or 24 rats. For the next month, one group of rats listened all day to heavy metal music by the group Anthrax. One group listened all day to Mozart. One group never heard music. The rats ran the same maze three times a week for a month. The response variable is the time in seconds to complete the maze. By the end of the month he compared the average run time for each treatment group to the average run time for the control group. The Anthrax group was much slower at running the maze. The Mozart group was much faster. The differences are statistically significant at the 1% level. Run times are not heavily skewed in any group. What conclusion can we draw from these results

Answers

Step-by-step explanation:

Heavy Metal "music" impacts negatively the long term memory, if at least the ability to access it.

while harmonic music has no blocking effect or maybe even strengthens the long term memory and the ability to access it.

here 3 remarks.

first 2 scientifically from psychology : memory works mostly associative. that means brains do not store absolute information like a digital computer, but always in combination and association with other pieces of information. if there is nothing else to remember (like a more or less random pattern of sound effects for that the brain cannot find a rule or concept for), there are no associations with presented pieces of information, and the storage and access to it is much harder and restricted.

and - loud crashing and seemingly random noise triggers the panic mode in our brains. and panic is the mode favoring pure instinct and suppressing cognitive functions.

and finally, personally, it just confirms what I literally feel when listening to such music : it destroys at that moment any ability to keep a straight thought, prolonged exposure gives me the feeling that something gets broken inside my brain and thought processes.

I suspect that this is exactly the feeling that the fans of this kind of music are after (kind of like most drugs), but I am not surprised that there actually is something broken in the brain (again, as with drugs).

Mo buys a house for £120 000 He sells the house for £150 000 Work out the percentage profit that Mo makes.

Answers

Step-by-step explanation:

profit amount=150000-120000

profit amount=30000

profit %= profit amount/cost price*100

therefore profit percent=30000/120000*100

there for profit %=25%

The percentage of profit will be equal to 25%

What is the percentage?

The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.

The profit percentage will be calculated as:-

Profit amount =  150000-120000

Profit amount  =  30000

Profit %= profit amount/cost price*100

Profit percent=30000/120000*100

Profit percentage = 25%

Therefore the percentage of profit will be equal to 25%

The ratio of the ages of Mandy and Sandy is 2:5. After 8 years, their ages will be in the ratio 1:2. What is the difference between their present ages?

Answers

A ratio shows us the number of times a number contains another number. Caitlin is right.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

The ratio of the ages of Mandy and Sandy is 2:5. Therefore, the ratio will be,

M/S = 2/5

M = 2S/5

After 8 years, their ages will be in the ratio 1:2, therefore,

(M+8)/(S+8) = 1/2

2M + 16 = S + 8

2M - S = -16 + 8

Substitute the value of M,

2(2S/5) - S = -8

-0.2S = -8

S = 40

Now, if we substitute the value of S in the first ratio,

M/S = 2/5

M/40 = 2/5

M = 16

Now, if we take the difference in their ages the difference will be 24(40-16).

Since the difference is 24, we can conclude that Caitlin is right.

Hence, Caitlin is right.

B. The function f(x) was translated right 3 units and down 2 units
C. The function f(x) was translated left 3 units and down 2 units
D. The function f(x) was translated right 3 units and up 2 units

Answers

The function g(x) is a translation to the right of 3 units and up 2 units of f(x), so the correct option is B.

Which statement is true regarding the vertical and horizontal translations from f(x) to g(x)?

For a given function f(x), we can write a vertical translation of n units as:

g(x) = f(x) + n

If n < 0, the translation is downwards.if n > 0, the translation is upwards.

And a horizontal translation of n units as:

g(x) = f(x + n).

if n > 0, the translation is to the left.if n < 0, the translation is to the right.

Here we have:

f(x) = (2/3)*x

g(x) = (2/3)*(x - 3) + 2

By comparing it with the general translations, we conclude that we have a traslation of 3 units to the right and 2 units up.

So the correct option is B.

Angles C and D are complementary. The ratio of the measure of Angle C to the measure of Angle D is 2:3. Find the measure of each angle. Explain or show your reasoning.

Answers

By using the ratio, we will see that angle C measures 36° and angle D measures 54°.

How to find the measure of the angles?

First, two angles are complementary if the sum of their measures gives 90°.

So we have:

C + D = 90°.

Also, we know that the ratio of C to D is 2:3

This means that we can divide the 90° in 5 parts (3 + 2 = 5) such that 2 of these parts are angle C, and the remaining 3 are angle D.

90°/5 = 18°

C = 2*18° = 36°

D = 3*18° = 54°

These are the measures of the angles.

On Monday a builder built 5/9 of a wall. On Tuesday he added the last 180 bricks to finish the wall. How many bricks are there in the wall?

Answers

Answer:

405

Step-by-step explanation:

So he built 5/9 of the wall, than added the extra 180 bricks to finish the wall.

so 5/9 + 180 = 9/9

so 180 = 4/9 Because 5/9 + 4/9 = 9/9

So to figure out how many bricks are in the wall we want to know what 1/9 of bricks equals and to work this out we need to divide 180 by 4

which equals 45.

Now we know that 1/9 = 45

so now to figure out what 9/9 is just multiply 45 by 9 which equals 405

Answer:

405 bricks in total

Step-by-step explanation:

1 - 5/9 = 4/9

So 4/9 of the bricks are remaining, and "the last 180 bricks" is equal to 4/9

Using ratio method:

4/9 : 180

5/9 : x

x = 180 × 5/9 ÷ 4/9

x = 225

So 180 + 225 = 405 bricks in total
