How are a carrot,amoeba,and a bacterium alike? I know this is science and not math but i need a quick answer.

Bas_tet [7]

yes and yes.

you're told ∠A=∠B. this means angle A and B are equal. so the value you get for cos A will be the same as the value you'll get for cos B

also, the value you get for tan A will be the same as the value you'll get for tan B

if that doesn't make sense you could also draw the triangle and solve for A and B.

you're told it's a right angled triangle meaning one of the angles = 90

you're told that C is that angle so if C is a right angle, angle C=90

the sum of all the angles in a triangle = 180

so angle A+ angle B + angle C = 180

angle A+ angle B + 90 = 180

angle A+ angle B = 180 - 90

angle A+ angle B = 90

A and B could be any value but you're told angle A = angle B

angle A+ angle B = 90

you can divide 90 by 2 because A and B are equal. that will give you 45 for A and 45 for B

or

angle A+ angle B = 90

since angle A = angle B,

1. you can substitute angle A with angle B like this

angle B+ angle B = 90

2 angle B = 90

angle B = 90/2

angle B=45; ∴ angle A is also 45 ( because angle A= angle B)

2. or you could substitute angle B with angle A

angle A+ angle A = 90

2 angle A = 90

angle A = 90/2

angle A =45; ∴ angle B is also 45 ( because angle A= angle B)

Now you know what A and B are,

sin A = sin 45; sin B = sin 45

sin 45 = sin 45

tan A = tan 45; tan B = tan 45

tan 45 = tan 45

jay beats terry at table tennis 3 out of 5 games. what is the experimental probability that terry will win their next game

lozanna [386]

Answer:

The experimental probability that terry will win their next game is $\frac{2}{5}$

Step-by-step explanation:

While theoretical probability is the ratio of the number of favourable outcomes to the total number of outcomes, the experimental probability is the ratio of number of times the event is occurring to the total number of trials of the experiment.

Out of 5 games jay wins 3

Now the experimental probability that terry will win their next game

= 1 - Probability of Jay winning the game----------------------(1)

Probability of Jay winning the game = $\frac{\text{number of occurrences of the event}}{\text{total number of trials made}}$

=> $\frac{3}{5}$ ----------------------------------------------------(2)

Substituting (2) in (1)

=> 1 - $\frac{3}{5}$

=> $\frac{5-3}{5}$

=> $\frac{2}{5}$
