Answer:

cos 0° = 1

Step-by-step explanation:

In given triangle sin 90° = 1

and we know the relation between cosine and sin is represented by

sin x = cos (90-x)

Therefore, sin 90° = cos ( 90-90 )

                              = cos 0°

                              = 1

Therefore, cos 0° = 1 will be the answer.

<span>sin 90° = 1
</span>
cos 0° = 1

There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>

So : cos 0° = sin (90° - 0°) = sin 90° = 1

What is the slope of the line created by this equation?Round your answer out to two decimal places.3x+5y=7
tia_tia [17]

The given equation is

3x+5y=7

Consider the slope-intercept form.

y=mx+b

Rewriting the given equation in the slope-intercept form.

3x+5y=7

Subtracting 3x from both sides, we get

3x+5y-3x=7-3x

Dividing both sides by 5, we get

\frac{5y}{5}=\frac{7-3x}{5}y=-\frac{3}{5}x+\frac{7}{5}

y=-0.6x+1.4

Compared to the slope-intercept form, we get m=-0.6 and b=1.4.

Hence the slope m= -0.60.

Researchers have discovered a new genetic marker for a form of cancer. Twelve percent of the overall population carry this marke
In-s [12.5K]

Answer:

The probability that a person with the marker develops cancer is 0.0725.

Step-by-step explanation:

Let's denote the events as follows:

<em>A</em> = a person has cancer

<em>B</em> = a person carries the marker.

<u>Given:</u>

P (A) = 0.03

P (B) = 0.12

P (B|A) = 0.29

The conditional probability of an event <em>X</em> provided that another event <em>Y</em> has already occurred is:

P(X|Y)=\frac{P(Y|X)P(X)}{P(Y)}

Use the conditional probability formula to compute the probability that a person with the marker develops cancer.

P(A|B)=\frac{P(B|A)P(A)}{P(B)} =\frac{0.29\times0.03}{0.12}=0.0725

Thus, the probability that a person with the marker develops cancer is 0.0725.
