1-sin60÷cos60=1-Tan30÷1+Tan30

Mathematics
1 answer:
ipn [44]4 years ago
8 0

Step-by-step explanation:

LHS=(1-sin60)/cos60

=(1-√3÷2)/1÷2

=2(1-√3÷2)

=2-√3

RHS=(1-tan30)/(1+tan30)

={1-(1÷√3)}/{1+(1÷√3)}

={(√3-1)/√3}/{(√3+1)/√3}

=(√3-1)/(√3+1)

={(√3-1)(√3-1)}/{(√3+1)(√3-1)}

=(3-√3-√3+1)/(3-1)

=(4-2√3)/2

=2-√3

Therefore LHS=RHS

A publisher reports that 30% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is
Ierofanga [76]

Answer:

Test statistic = - 2.29

Pvalue = 0.0110

Step-by-step explanation:

The hypothesis :

H0 : p = 0.3

H1 : p < 0.3

Test statistic :

z=pˆ−p/√p(1−p)/n

pˆ = 0.2

Z = (0.20 - 0.30) / √(0.30(1 - 0.30) / 110

Z = - 0.1 / √0.0019090

Z = - 0.1 / 0.0436931

Z = - 2.29

Test statistic = -2.29

The Pvalue :

P(Z < -2.29) = 0.0110

You ride an express bus from the center of town to your street. You have two payment options. Option A is to buy a monthly pass
34kurt

Answer:

Step-by-step explanation:

Let x represent the number of miles after which the cost of both options will be the same.

You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. This means that the total amount that you would pay for x miles if you use this option is

0.8x + 30

Option B is to pay $2.30 per ride. This means that the total amount that you would pay for x miles if you use this option is

2.3x

An equation to show after how many rides the cost will be the same would be

0.8x + 30 = 2.3x

2.3x - 0.8x = 30

1.5x = 30
