The measure of variation for a numerical data set describes how the values of a number vary with the single number. This measurement shows the difference in the properties of a certain number to the rest of the numbers in the numerical data set.

The line with equation a + 4b = 0 coincides with the terminal side of an angle θ in standard position and cos θ>0 . What is t

Nikitich [7]

Answer:

$\frac{-1}{\sqrt{17} }$

Step-by-step explanation

We have given that equation of line a+4b=0

⇒4b= -a

⇒ $b= \frac{-a}{4}$

slope of line = $tan\theta =\frac{P}{B}= \frac{-1}{4}$

⇒ $tan\theta$ is negative therefore it lies into 4th quadrant

By, Pythagoras theorem $H^2=P^2+B^2$

by putting value of P= -1 & B=4

the value of $H=\sqrt{17}$

with the given condition $cos\theta>0$

i.e. $\theta$ ∈ (3π/2, 2π)

now, $sin\theta= \frac{P}{H}= \frac{-1}{\sqrt{17}}$

If Anna have 8000 and gave jim 300 and bought some items a shoes for 290 a suit for 400 and a phone for 2000

vovangra [49]

Answer: Assuming the unit is dollars, the answer would be $5,010.

Explanation:

Step 1: 8000-300 is 7700.

Step 2: 7700-290 is 7410

Step 3: 7410-400 is 7010

Step 4: 7010-2000 is 5010

So, the answer is Anna has $5,010 dollars left after giving Jim $300, buying shoes for $290, a suit for $400 and spending $2,000 dollars on a new phone.

A line with a slope of -1/3 passes through the point (9,3). What is its equation in point-slope form?

amm1812

The point-slope form:

$y-y_1=m(x-x_1)$

We have:

$(9,\ 3)\to x_1=9,\ y_1=3\\\\m=-\dfrac{1}{3}$

Substitute

$y-3=-\dfrac{1}{3}(x-9)$

Lane high school has 5 times as many students as park elementary. How many more students attend lane high school than park high

frosja888 [35]

Answer:

5 times as many

<em>BRAINLIEST, please!</em>

Step-by-step explanation:

I'd need more information about how many students there are at one of the schools. For example, if there are 200 students at Park Elementary, then there are 1000 at Lane High School since 200 x 5 = 1000. 1000 - 200 is 800, so there would be 800 more students at Lane High.

How many times greater is 70 million than 7 million

Dahasolnce [82]

For this case we have the following expressions:

70,000,000

7,000,000

If we divide the first expression by the second we have:

$\frac {70,000,000} {7,000,000} = 10$

Thus, we have that the first expression is 10 times greater than the second expression.

Answer:

70,000,000 is 10 times greater than 7,000,000
