inessss [21]

Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

Length of MN ( Base ) = 8
Length of NL ( Hypotenuse ) = 10

$\underline{ \underline{ \text{To \: find}}} :$

Length of LM ( Perpendicular )

$\underline{ \underline{ \text{Using \: pythagoras \: theorem}}} :$

$\boxed{ \sf{ {Hypotenuse}^{2} = {Perpendicular}^{2} + {Base}^{2} }}$

⤑ $\sf{ Perpendicular = \sqrt{ {(Hypotenuse)}^{2} - {(Base)}^{2} } }$

⤑ $\sf{ \sqrt{ {(10)}^{2} - {(8)}^{2} } }$

⤑ $\sf{ \sqrt{100 - 64}}$

⤑ $\sf{ \sqrt{36}}$

⤑ $\boxed{ \sf{6\: units}}$

$\pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline { \tt{6 \: units}}}}}}}$

Kyle asked a random group of students what their favorite sport was. The results are below. Boys Girls Basketball 10 8 Football

Ronch [10]

Answer:

The probability that Kyle will pick a girl who likes football is 12.5%.

Step-by-step explanation:

The data provided is as follows:

Boys Girls Total

Basketball 10 8 18

Football 25 7 32

Soccer 9 19 28

Baseball 18 22 40

Total 62 56 118

Compute the probability that Kyle will pick a girl who likes football as follows:

$P(F|G)=\frac{n(G\cap F)}{n(G)}$

$=\frac{7}{56}\\\\=0.125\\\\=12.5\%$

Thus, the probability that Kyle will pick a girl who likes football is 12.5%.
