Answer:

Angel two measures 60.4.

Step-by-step explanation

Since you are given one number, you would just have to subtract that from 90. (Easiest way to explain) Complementary angels are when the sum of both angels add up to 90°.

The equation of the line is y = 1/6x + 3

<h3>How to determine the equation?</h3>

The equation of the line is given as:

y = -6x - 14

The above equation has a slope of

m = -6

Let the slope of the other line be n.

So, we have:

n =-1/m ---- slope condition for perpendicular lines

So, we have:

n = 1/6

The equation is then calculated as:

y = n(x - x1) + y1

Where

(x1, y1) = (12,5)

This gives

y = 1/6(x - 12) + 5

Expand

y = 1/6x - 2 + 5

Evaluate the sum

y = 1/6x + 3

Hence, the equation of the line is y = 1/6x + 3

A scientist claims that 7% 7 % of viruses are airborne. If the scientist is accurate, what is the probability that the proportio

Reptile [31]

Answer:

The probability is $P(|p-\^{p}| > 0.03) = 0.0040$

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.07$

The mean of the sampling distribution is $\mu_p = 0.07$

The sample size is n = 600

Generally the standard deviation is mathematically represented as

$\sigma_p = \sqrt{\frac{p (1 -p)}{n} }$

=> $\sigma_p = \sqrt{\frac{0.07(1 -0.07)}{600} }$

=> $\sigma_p = 0.010416$

Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as

$P(|p-\^{p}| > 0.03) = 1 - P(|p -\^{p}| \le 0.03)$

=> $P(|p-\^{p}| > 0.03) = 1 - P(-0.03 \le p -\^{p} \le 0.03 )$

Now add p to both side of the inequality

=> $P(|p-\^{p}| > 0.03) = 1 - P( 0.07-0.03 \le \^{p} \le 0.03+ 0.07 )$

=> $P(|p-\^{p}| > 0.03) = 1 - P(0.04 \le \^{p} \le 0.10 )$

Now converting the probabilities to their respective standardized score

=> $P(|p-\^{p}| > 0.03) = 1 - P(\frac{0.04 - 0.07}{0.010416} \le Z \le \frac{0.10 -0.07}{0.010416} )$

=> $P(|p-\^{p}| > 0.03) = 1 - P(-2.88 \le Z \le 2.88 )$

=> $P(|p-\^{p}| > 0.03) = 1 - [P(Z \le 2.88) - P(Z \le -2.88)]$

From the z-table

$P(Z \le 2.88) = 0.9980$

and

$P(Z \le -2.88) = 0.0020$

$P(|p-\^{p}| > 0.03) = 1 - [0.9980 - 0.0020]$

=> $P(|p-\^{p}| > 0.03) = 0.0040$

The taxes on a piece of property valued at $40,000 were $860. At the same rate, what would be the taxes on property valued at $5

agasfer [191]

Ratio and Proportion Method
Since both are at the same rate, then ratio and proportion can be applied here

If $40000 = $860

Then $55000 =55000x(860/40000)
=$1182.50

Therefore the taxes which would be on $55000 is $1182.50
