Answer with explanation:

There are two sine ratios, two cosine ratios, and two tangent ratios for any right triangle. It totally depends where the terminal side of right triangle lies. If it lies in first quadrant all trigonometric ratios will be positive .In second quadrant Sine and Cosecant of any angle will be positive.In Third tan and cot of any angle will be positive.And in fourth Quadrant secant and cos of any angle will be positive.So, there is one positive and one negative value of any of the trigonometric function.That's why all the trigonometric function have two real values.

Each angle has a sin, cos, and tan associated with it.
in a right angled triangle there are two other angles which each have ratios.

MArishka [77]

Answer:

The probability is $P(J|B) = 0.36$

Step-by-step explanation:

B =business

J=jumbo

Or =ordinary

From the question we are told that

The proportion of the passenger on business in the ordinary jet is $P(B| Or) = 0.25$

The proportion of the passenger on business in the jumbo jet is $P(B|J) = 0.30$

The proportion of the passenger on jumbo jets is $P(j) = 0.40$

The proportion of the passenger on ordinary jets is evaluated as

$1 - P(J) = 1- 0.40 = 0.60$

According to Bayer's theorem the probability a randomly chosen business customer flying with Global is on a jumbo jet is mathematically represented as

$P(J|B) = \frac{P(J) * P(B|J)}{P(J ) * P(B|J) + P(Or ) * P(B|Or)}$

substituting values

$P(J|B) = \frac{ 0.4 * 0.25}{0.4 * 0.25 + 0.6 * 0.3}$

$P(J|B) = 0.36$

A moderately active 140 pound person will use 2100 calories per day to maintain that body weight, how many calories per day are

blondinia [14]

Answer:

2,175 calories

Step-by-step explanation:

140 pound person will use 2100 calories per day

145 pounds person will use x calories per day

Find x

Pounds : calories

140 : 2100 = 145 : x

140/2100 = 145/x

Cross product

140 * x = 2100 * 145

140x = 304,500

Divide both sides by 140

x = 304,500 / 140

= 2,175

Therefore,

145 pounds person will use 2175 calories per day

Erin built a wooden box to hold hay on her farm. Hay costs $14dollar sign, 14 per cubic meter. How much will it cost to complete

sergiy2304 [10]

Here is the complete question.

Erin built a wooden box to hold hay on her farm.The box is 3 \text { m}3 m3, start text, space, m, end text long, 1 \text { m}1 m1, start text, space, m, end text wide, and 1 \text { m}1 m1, start text, space, m, end text high.Hay costs $14dollar sign, 14 per cubic meter. How much will it cost to completely fill the box with hay?

Answer:

it cost $42 to completely fill the box with hay

Step-by-step explanation:

Given that :

The length of the wooden box = 3m ; the width of the box = 1m and the height of the box = 1 m; we can easily determine the volume of the rectangular wooden box;

We all know it would assume the shape of a rectangular prism and it's volume = L × W × H

Thus; the volume of the box = . 3 m × 1 m × 1 m = 3 m³

However, the question proceeds by stating it that the wooden box cost $14 per cubic meter;

So , if 1 cubic meter = $14;

three cubic meters = $14 × 3 = $42

Hence; it cost $42 to completely fill the box with hay
