Answer:

0

Step-by-step explanation:

From a horizontal distance of 80m, the angle of elevation to the top of a flagpole is 180. Calculate the height of the flagpole.

We solve the above question using the trigonometric function of Tangent

The formula is given as:

tan θ = Opposite/ Adjacent

θ = 180°

Adjacent = 80m

Opposite = Height = x

Hence,

tan 180 = x/80

Cross Multiply

x = tan 180 × 80

x = 0m

The height of the flag = 0

A drug company conducts trials of a new vaccine for a rare but usually fatal disease. The company creates a
GalinKa [24]

Answer:

What can be said about the model are;

1) The company predicts 4 failures before success

2) Each trial is independent

3) The probability is the same for each trial

4) Success is defined as preventing the disease

Step-by-step explanation:

The probability of success for the vaccine, p = 0.2

Therefore, the probability that the vaccine is effective and prevents the disease = 0.2

A geometric distribution probability of success is given by the following formula;

P(X = x) = p × q⁽ˣ⁻¹⁾

The expected value, E(Y) = 1/p

The number of failures before success, E(Y) = (1 - p)/p = (1 - 0.2)/0.2 = 4

Where;

q = The probability of a trial failing = 1 - p = 1 - 0.2 = 0.8

q = 1 - p

∴ The e

The geometric model criteria are;

a) Each trial can only have one of two outcomes success or failure

b) The probability of success for each trial is fixed

c) The geometric distribution is concerned with finding how many trials are required to get one success

d) The trials are independent

Therefore, we have;

The number of failures the company predicts before a success = 4 failures

2) The trials are independent

3) Each trial has an equal probability

4) Success is defined by the effectiveness of the vaccine in the prevention of the disease

Fifty people were surveyed about their favorite flavor of frozen yogurt. The results of the survey are displayed in the circle g
Ksju [112]

The answer is 2. This is because 2 = 4% of 50.

You can think of it like this:

4 is 4% of 100.

50 is half of 100.

Therefore, 4% of 50 is HALF of 4% of 100.

4 divided by 2 = 2

Alika [10]
<h3>Answer:</h3>

$200

<h3>Explanation:</h3>

Let p represent the price last year. Then the price this year is ...

... (price this year) = p + 15%×p

... = p + 15/100×p = 1.15p

The price after the employee discount is ...

... (price this year) - 25%×(price this year)

... = (price this year)×(1 - 25/100) = 0.75×(price this year)

Then the price paid is ...

... $172.50 = 0.75×(1.15p) = 0.8625p

Dividing by the coefficient of p, we have

... $172.50/0.8625 = p = $200

The price last year was $200.
