Find the mean absolute value of 0.4, 0.2, 0.4, 0.6

1 answer:

suter [353]3 years ago

5 0

Answer: I think it's 0.4

Step-by-step explanation:

Adding all the numbers together (0.2; 0.4; 0.4; 0.6) gives you 1.6 which, when divided by the amount of numbers, gives you 0.4. If that isn't the kind of mean you're referring to. It'd still be 0.4 because it is the value in the middle of all given numbers.

What is the equation of the line that passes through (-3,-1 ) and has a slope of 3/5

vfiekz [6]

The point-slope form:

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

We have the point (-3, -1) and the slope m = 3/5. Substitute:

$y-(-1)=\dfrac{3}{5}(x-(-3))\\\\y+1=\dfrac{3}{5}(x+3)\qquad\text{use distributive property}\\\\y+1=\dfrac{3}{5}x+\dfrac{9}{5}\qqua\text{subtract 1 from both sides}\\\\y=\dfrac{3}{5}x+\dfrac{4}{5}\qquad\text{multiply both sides by 5}\\\\5y=3x+4\qquad\text{subtract 3x from both sides}\\\\-3x+5y=4\qquad\text{change the signs}\\\\3x-5y=-4$

Answer:

point-slope form: y + 1 = 3/5(x + 3)

slope-intercept form: y = 3/5x + 4/5

standard form: 3x - 5y = -4

Bisect the angle a b c

vlada-n [284]

Answer:

BR bisects the angle ABC, and is called the bisector of angle ABC.

Step-by-step explanation:

Step 1: Draw an arc with B as the centre to cut the arms, BA and BC, of the angle at P and Q respectively.

Step 2: Using the same radius, draw an arc centred at P.

Step 3: With centre Q and using the same radius, draw an arc to cut the arc in Step 2 at R.

Step 4: Join, B, the vertex of the angle to the point R.

Ellen flipped a coin 80 times. the coin landed heads up 44 times and tails up 36 times. what is the experimental probability of

Vaselesa [24]

Answer:

$\frac{9}{20}$

Step-by-step explanation:

experimental probability is the probability of an event occuring when we perform an experiment.

It goes according to the results of the experiment, not the theory behind it.

<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>

<u />

Hence

P (tails) = 36/80 = 9/20
