Answer:

20 is one possible answer

24 is another possible answer The question is ambiguous

Step-by-step explanation:

First put what you have in order. The median is the central number.

12 18 22 26 30

The median for this case is not listed in your answers. 22 is not there.

So we have to give some thought to what the sixth number was. Unfortunately that leads to two possible answers

If the missing number is less than 12, the the median will be between 18 and 22. Say the missing number is 10

10 12 18 22 26 30

(18 + 22)/2 = 20 would be the answer.

However if the missing number was greater than 26 (say it was 32) then the numbers would be

12 18 22 26 30 32 the average between the 3rd and 4th numbers.

(22 + 26)/2 = 48/2 = 24

Both answers are possible and are listed. There is no single answer.

C) because the numbers are going up by 6 and the erased number was 28 now that leaves 26 and 22 and when there's 2 numbers left you see what number is between those numbers which is 24.

What is the equation for a line passing through (-2,3) and perpendicular to y= -1/2+1 ?
nata0808 [166]

Answer:

y=2x+7

Step-by-step explanation:

<u><em>The correct question is</em></u>

what is the equation for a line passing through (-2,3) and perpendicular to y= -1/2<em>x</em>+1 ?

Remember

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes are equal to -1)

The slope of the given line is m=-1/2

so

the opposite reciprocal is m=2

<em>Find the equation of the line in point slope form</em>

y-y1=m(x-x1)

we have

m=2\\point\ (-2,3)

substitute

y-3=2(x+2)

<em>Convert to slope intercept form</em>

y=mx+b

isolate the variable y

y-3=2x+4

y=2x+4+3

y=2x+7

[[ 20 POINTS IF YOU ANSWER THIS QUESTION CORRECTLY. ]]
dezoksy [38]

Answer: the height of the kite is 106.065 ft

Step-by-step explanation:

The length of the kite represents the hypotenuse of the right angle triangle. The height of the kite represents the opposite side of the right angle triangle.

To determine x, the height of the kite, we would apply the sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse

Therefore,

Sin 45 = x/150

Cross multiplying, it becomes

x = 150Sin45 = 150 × 0.7071

x = 106.065 ft
