Does anyone know how to answer this question I'm having a lot of trouble with it?

Helen [10]

Answer:

h = $\frac{2A}{(b+c)}$

Step-by-step explanation:

Formula for the area of a trapezoid is,

Area (A) = $\frac{1}{2}(b+c)h$

Here b and c are the bases and 'h' is the height of the trapezoid.

2A = $2[\frac{1}{2}(b+c)h]$

2A = (b + c)h

$\frac{2A}{(b+c)}=h$

Therefore, formula for the height of the trapezoid will be,

h = $\frac{2A}{(b+c)}$

stiv31 [10]

Answer:

a) 0.1 = 10% probability of a tip of $200 or more.

b) 0.4 = 40% probability of a tip of up to $50.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Distribution:

Total of 500 checks.

200 with tips in the interval of 0-20.

100 with tips in the interval of 20-50.

75 with tips in the interval of 50-100.

75 with tips in the interval of 100-200.

50 with tips of 200 or more.

a) What is the probability of a tip of $200 or more?

50 out of 500. So

$p = \frac{50}{500} = 0.1$

0.1 = 10% probability of a tip of $200 or more.

b) What is the probability of a tip of up to $50?

200 out of 500. So

$p = \frac{200}{500} = 0.4$

0.4 = 40% probability of a tip of up to $50.

Evaluate and simplify tan 15º.

dimulka [17.4K]

Tan(15) = tan(45 - 30)

= [tan(45) - tan(30) ] / [ 1 + tan(30)tan(45)]

= (1 - 1/sqrt(3)) /(1 + 1/sqrt(3))

= (sqrt(3) - 1)/(sqrt(3) + 1)

= (sqrt(3) - 1)^2 /(3 - 1)

= 1/2 [3 + 1 - 2sqrt(3) ]

= (2 - sqrt(3) )

= 0.27 is your answer
