Vaimiti walks at a constant pace of 1.1 m/s and takes 25 minutes to get to school.

Temka [501]

Solution:

Note that:

Speed = Distance/Time
Vaimiti speed = 1.1 m/s
Jabril speed = 1.3 m/s

Converting the time (minutes to seconds) for Vaimiti to reach school:

Vaimiti's time to reach school: 25 minutes = 25 x 60 seconds
=> Vaimiti's time to reach school: 1500 seconds

Converting the time (minutes to seconds) for Jabril to reach school:

Jabril's time to reach school: 30 minutes = 30 x 60 seconds
=> Jabril's time to reach school: 1800 seconds

Finding the distance of Vaimiti:

Speed = Distance/Time

Important: The distance will be in meters since the speed units is meters/seconds.

=> 1.1 meters/second = Distance/1500
=> 1.1 x 1500 = Distance
=> 1650 meters = Distance (In meters)

Finding the distance of Jabril:

Speed = Distance/Time

Important: The distance will be in meters since the speed units is meters/seconds.

1.3 meters/second = Distance (In meters)/1800 seconds
=> 1.3 x 1800 = Distance (In meters)
=> 2340 meters = Distance (In meters)

This can lead to two possible solutions:

Possible solution #1:

Finding the difference between the two distances:

2340 meters - 1650 meters = Difference (In meters)
=> 690 meters

Possible solution #2:

The difference between the distances they walked is that Jabril walked faster than Vaimiti, but Vaimiti reached school earlier than Jabril because the walking distance for Vaimiti is less than the walking distance for Jabril.

Hoped this helped!

Answer:

z=-3

Step-by-step explanation:

The given line has slope m=-7.

The line passes through (-1,-8) and (z,6).

We use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

We substitute $x_1=-1$ , $y_1=-8$ , $x_2=z$ , $y_2=6$ and $m=-7$ to get:

$-7=\frac{6--8}{z--1}$

$-7=\frac{6+8}{z+1}$

$-7=\frac{14}{z+1}$

$-7(z+1)=14$

Expand $-7z-7=14$

$-7z=14+7$

$-7z=21$

$z=-3$

A genius society requires an IQ that is in the top 2% of the population in order to join. If an IQ test has a mean of 100 and a

Svetach [21]

The minimum score to join the genius society is 130.

What is the probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given

A genius society requires an IQ that is in the top 2% of the population in order to join.

If an IQ test has a mean of 100 and a standard deviation of 15.

The top 2%, you have to have an IQ higher than 98% of the population (100% - 2%).

This is also known as the 98th percentile.

For this problem, you are given the probability and need to determine the raw score.

The closest probability is 0.97982 and that corresponds to a z-score of 2.05.

$\rm z - score=\dfrac{x-mean}{standard \ deviatiion}\\\\2.05=\dfrac{x-100}{15}\\\\x-100=15\times 2.05\\\\x-100=30.75\\\\x=100+30.75\\\\x=130.75$

Hence, the minimum score to join the genius society is 130.

What is the radius of a circle with an area of 212 in squared. please please simplify for me....

Nikitich [7]

Answer:

8.22in

Step-by-step explanation:

Area of circle = πr²

r is the radius

Given

Area = 212in²

Substitute

212 = πr²

r² = 212/3.14

r² = 67.52

r = √67.52

r = 8.22in

hence the radius of the circle is 8.22in
