Answer:
There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
A piano instructor examined student progress. She noticed that when students spend less time playing video games, their memorization ability tends to increase. What can she conclude?
There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further studies would have to be done to determine this.
The piano instructor observes changes in the number of video games
played and its effects on the memorization ability.
What she can conclude is; A. There is no correlationReasons:
The aim of the experiment is to check if there is a correlation between the
time students spend playing video games and their memorization ability.
The observation made following a reduction in the time the student spend
playing video games and their memorization ability is that there is no
change in the memorization ability of student following a change in the
time spent playing video games.
The conclusion that can be made is that there is no relationship between
the time the student spends playing video games and their memorization
ability.
The time spent playing video game and memorization are not correlated.
Therefore, the correct option is; A. there is no correlationLearn more about correlation here:

What’s the y-intercept of the line graphed on the grid?
Answer:
y-intercept is 4.5
Step-by-step explanation:That is when the line intersects the y-axis
Answer:
y intercept = 5.5
Step-by-step explanation:
The y-axis is the vertical (up and down) line in the center of the graph. When the line passes over it, wherever it passes, will be your y intercept.
In this situation it passes in the middle of 5 and 6 so it would be 5.5.

Was wondering what it meant byexpress as a power of 2?
Answer:
Expressing a number in a power of 2 means that you have to figure out how many times you should multiply 2 by itself so the product will be that number.
The number is expressed as 2^n
For example:
Express 16 as a power of 2:
To get 16, you have to multiply 2 by 4 times.
2 × 2 × 2 × 2 = 16
16 = 2^4
Then the answer is 2^4
Sarah invested $3,800 in an account paying an interest rate of 3.6% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 15 years?
Answer:
6500
Step-by-step explanation:
A=P(1+nr)nt
Compound interest formula
P=3800
r=0.036
t=15
n=365
P=3800r=0.036t=15n=365
Given values
A=3800 (1+0.036 365)
365(15)
A=3800(1+365 0.036)
365(15)
Plug in values
A=3800(1.0000986301) 5475
A=3800(1.0000986301)
5475
Simplify
A=6520.65243954
A=6520.65243954
Use calculator
A≈6500
A≈6500
Round to nearest hundred
The amount in account after 15 years will be $6500
What is compound interest ?Compound interest is the interest you earn on interest.
Given that, Sarah invested $3,800 in an account paying an interest rate of 3.6% compounded daily.
Compound interest formula;
A = P(1+r/n)^nt
We have,
P = 3800
r = 0.036
t = 15
n = 365
P = 3800 r = 0.036 t = 15 n = 365
Putting the values and on simplification, we get,
A = 3800(1+0.036 365)365(15)
A = 3800(1+365 0.036)365(15)
A = 3800(1.0000986301)5475
A = 3800(1.0000986301)5475
A = 6520.65243954
A = 6520.65243954
A ≈ 6500
A ≈ 6500
Hence, The amount in account after 15 years will be $6500

Consider 3 trials, each having the same probability of success. Let X denote the
total number of successes in these trials. If E(X) = 1.8, the smallest possible value of Pr{X = 3}?
Construct a probability scenario that results in Pr{X = 3} having the stated value.
(Hint: For part (b), you might start by letting U be a uniform random variable on (0,1) and then defining the trials in terms of the value of U.)
Solve using hint
Answer:
The smallest possible value of Pr{X = 3} is U = 0
Step-by-step explanation:
The number of trial is n = 3
The mean is E(X) = 1.8
Gnerally given that every probability value lies between 0 and 1 ,
let U be the smallest possible value of Pr{X = 3}
it then mean that U= 0 because in the range which probability values can take , the smallest value is zero
So
The smallest possible value of Pr{X = 3} is U = 0

Two secant segments are drawn to a circle from a point outside the circle. The external segment of the first secant segment is 8 centimeters and its internal segment is 6 centimeters. If the entire length of the second secant segment is 28 centimeters, what is the length of its external segment?
Given:
Two secant segments are drawn to a circle from a point outside the circle.
External segment of the first secant segment = 8 centimeters
Internal segment of the first secant = 6 centimeters.
Entire length of the second secant segment = 28 centimeters.
To find:
The length of its external segment.
Solution:
Let x be the length of its external segment.
Entire length of the first secant segment = 8+6 = 14 centimeters.
If two secant segments are drawn to a circle from a point outside the circle, then product of entire length of first secant and external length of first secant is equal to product of entire length of second secant and external length of second secant.
[tex]14\times 8=28\times x[/tex]
[tex]112=28x[/tex]
Divide both sides by 28.
[tex]\dfrac{112}{28}=x[/tex]
[tex]4=x[/tex]
Therefore, the length of external segment of second secant is 4 centimeters.

Which scenario is an example of the transfer of thermal energy by radiation?
A. Leftovers are warmed in a microwave oven.
O B. A person's body temperature falls as the person swims in the
ocean.
C. Warm air near a heater spreads out to the rest of the room.
D. A piece of chocolate melts in a person's hand.
Answer:
A
Step-by-step explanation:
The scenario that is an example of the transfer of thermal energy by radiation is warm air near a heater spreads out to the rest of the room. That is option C.
What is radiation?Radiation is the transfer of heat energy from an environment to another through movement of air in the space between them. There is no medium that is required for this transfer.
From the options, the warm air from the heater spreads out to the rest of the room through the movement of air.
Therefore, the scenario that is an example of the transfer of thermal energy by radiation is warm air near a heater spreads out to the rest of the room.
