A football team carried out a report to see the impact of stretching on preventing injury. Of the 50 footballers in the squad 32 stretch regularly. Of those who stretch, 4 got injured last year. There was a total of 19 injured players last year.
The results can be presented in a frequency tree. What fraction of players who do stretch get injured?

Answer:

Step-by-step explanation:

40 miles per minute

Explanation:

So any decimal number is the same as a percentage but take off ONE zero in front of it

So with 0.24 for example, you take off the zero in front and since there are no zeros for the decimal point to be behind, there is no need for the decimal point now, so the percentage is 24%

Answer:

[tex]\boxed {\boxed {\sf \$9,534.37}}[/tex]

Step-by-step explanation:

The formula for continuously compounded is:

[tex]A=Pe^{rt}[/tex]

where P is the principal amount, r is the interest rate as a decimal, and t is the amount of time.

The principal amount is $7,500 and time is 16 years. The interest rate is 1.5%. Convert this to a decimal- divide by 100 or move the decimal places two spots to the left.

Now we know all the values and can substitute them into the formula.

[tex]P= 7500 \\r= 0.015 \\t= 16[/tex]

[tex]A= 7500(e^{0.015*16})[/tex]

Solve the multiplication in the exponent first.

[tex]A= 7500(e^{24})[/tex]

Solve the exponent.

[tex]A= 7500 (1.27124915)[/tex]

[tex]A=9534.368627[/tex]

Round to the nearest cent (hundredth place). The 8 in the thousandth place tells us to the round the 6 to a 7.

[tex]A=9534.37[/tex]

The account balance will be $9,534.37 after 16 years.

Answer:

∠ A = 30°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

90 + x + 67 + x + 37 = 180, that is

2x + 194 = 180 ( subtract 194 from both sides )

2x = - 14 ( divide both sides by 2 )

x = - 7

Then

∠ A = x + 37 = - 7 + 37 = 30°

Answer:

$581.25

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.25%/100 = 0.0325 per year,

then, solving our equation

I = 500 × 0.0325 × 5 = 81.25

I = $ 81.25

The simple interest accumulated

on a principal of $ 500.00

at a rate of 3.25% per year

for 5 years is $ 81.25.

Answer:

Step-by-step explanation:

The complement of "x" is "90-x".

The complement of 55 degrees is 90-55 = 35 degrees

--------------

The supplement of "x" is 180 -x.

The supplement of 170 degrees is 180-170 = 10 degrees.

Answer: 0.82 laps per minute

Step-by-step explanation:

Lin is running 21 laps in 25.6 minutes.

To find out her speed in laps per minute, divide the distance she has ran by the time it took her to run it.

= Distance / time

= 21 / 25.6

= 0.82 laps per minute

Answer:

multiplying by 1.44 is the same as increasing by 44%

Step-by-step explanation:

this is because 44+100 divided by 100 is 1.44

The value of x is: x = 35.57.

Here, we have,

given that,

from the given diagram, we get,

it is a right angle triangle,

base = x

hypotenuse = 37

and angle = 16°

now, we know that,

cos θ = adjacent / hypotenuse

so, we get,

cos 16° = x/37

The value of cos 16° is equal to the x-coordinate (0.9613).

∴ cos 16° = 0.9613.

=> 0.9613 = x/37

=> x = 35.57

Hence, The value of x is: x = 35.57.

Answer:

f(-4)=-2(-4)²+8(-4)-10=-2×16-32-10=-74

Step-by-step explanation:

Given

f(x) = - 2x² + 8x - 10

f(-4) = - 2 * (-4)² + 8 * ( -4 ) - 10

= - 32 - 32 - 10

= - 74

Step-by-step explanation:

s = cost of senior ticket

c = cost of child ticket

System of Equations:

8s + 7c = 211

4s + 6c = 138

I used the elimination method and multiplied the second equation by -2

-8s - 12c = -276

add the above to the first equation and get

-5c = -65

c = 13

now find s

8s + 7(13) = 211

8s + 91 = 211

8s = 120

s = 15
