A football team carried out a report to see the impact of stretching on preventing injury. Of the 60 footballers in the squad 48

stretch regularly. Of those who stretch, 8 got injured last year. There was a total of 17 injured players last year. The results can be presented in a frequency tree. What fraction of players are not stretching regularly?

Answer:

the fraction of players are not stretching regularly is 1 ÷ 5

Step-by-step explanation:

The computation of the fraction of the players not stretching regularly is as follows;

Given that

There are total number of 60 footballers

Out of which 48 strech regularly

So, the players who are not streching properly is

= 60 - 48

= 12

Now the fraction is

= 12 ÷ 60

=  1 ÷ 5

hence, the fraction of players are not stretching regularly is 1 ÷ 5

Classify the number as rational or irrational: 4.126532
Oksana_A [137]

That's the ratio of 4,126,532 to 1,000,000 so it's rational.

Here's a little factoid that I never see mentioned anywhere, but I think it can be really helpful to know:

==> Any number that you can WRITE DOWN COMPLETELY using digits (plus a decimal point or a fraction bar if you need them) is a rational number.

If " 4.126532 " is the whole thing, you sure nuff wrote it down, so it's rational.

The weight of a radioactive isotope was 96 grams at the start of an experiment. After one hour, the weight of the isotope was ha
zimovet [89]
The starting weight of the radioactive isotope = 96 grams

Weight after one hour is half of the starting weight. So the weight of the radioactive isotope after 1 hour = 48 grams

After 2 hours the weight is half as compared to the weight after previous hour. So weight after 2 hours = 24 grams.

This means, after every hour the weight is being halved. The half life of radioactive isotope is one hour.

Since after every hour, the weight is being halved, the weight of the isotope can be modeled by an exponential equation.

So,

Initial Weight = W₁ = 96
Change factor = 1/2 = 0.5

The general equation of the sequence will be:

\\  \\ W_{t}=96(0.5)^{t}

Here t represents the number of hours. Using various values of t we can find the weight of the radioactive isotope at that time.

We can plot the sequence using the above equation. The graph is attached below.

The sector of a circle is shown below. It has a radius of 10 centimeters and a central
disa [49]

Answer:

1) 8.9 cm

2) 44.5 cm^2

Step-by-step explanation:

a) we want to calculate the length of the arc

Mathematically, we use the formula for the length of an arc

That will be ;

theta/360 * 2 * pi * r

theta = central angle = 51

r is radius = 10 cm

so we have ;

51/360 * 2 * 22/7 * 10 = 8.9 cm

2) The area of the sector is;

theta/360 * pi * r^2

51/360 * 22/7 * 10^2

= 44.5 cm^2
