Answer:

pls mark brainliest if possible:

slope is 1.5

Step-by-step explanation:

Slope = rise over run = (y2-y1)/(x2-x1)

choose y2 and corresponding x-coordinate is x2. If we choose 27 as y2, then:

x2 = 1

x1 = -9

y1 = 2

then plug everything into the equation

(27-2)/(1-(-9))

=15/10

= 1.5

slope is 1.5

hope this helps!

Given that cos theta = -12/13 and theta is in the second quadrant, find this function. sin theta=​

5/13

The x value is negative (second quadrant). 13 is the hypotenuse. So the missing side is 13^2 = (-12)^2 + y^2.

Sin theta is the opposite (5) over hypotenuse (13).

9. Gold miners in Alaska have found, on average, 12 ounces of gold per 1000 tons of dirt excavated with a standard deviation of
netineya [11]

Answer:

9.18% probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 12, \sigma = 3

What is the probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated?

This is 1 subtracted by the pvalue of Z when X = 16. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{16 - 12}{3}

Z = 1.33

Z = 1.33 has a pvalue of 0.9082

1 - 0.9082 = 0.0918

9.18% probability the miners find more than 16 ounces of gold in the next 1000 tons of dirt excavated

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given series  1 -0.5 -2 +.........

we know that the sum of the sequence is called a series

The sequence is 1, -0.5, -2, -3.5,.....is in AP

a = 1 and the difference between the two terms is equal 'd' = -1.5

<u><em>Step(ii):-</em></u>

<u><em>adding 1.5 value of each term</em></u>

The series

            1 -0.5-2-3.5 -5-6.5-8-9.5-11-12.5-14-15.5 upto 12 terms
