Before outlier : 7.25
After outlier : 4

7.25 - 4 = 3.25

So the mean decreases by 3.25 when the outlier is removed.

Which of the equations below could be the equation of this parabola?
BARSIC [14]

Parabolas like y=ax^2 have the y-axis as their symmetry axis, so options B and D are surely wrong.

Moreover, parabolas like x=ay^2 have the x-axis as their symmetry axis. If a>0 the parabola is concave rightwards, if a the parabola is concave leftwards.

Since your parabola is concave leftwards, the only feasible option is x=-2y^2

Hey can someone tell me why 132 is wrong? and help me with the right answer pls
andreev551 [17]

Answer:

∠CBA = 132

Step-by-step explanation:

Bisectors split up an angle into two identical angles

Thus, 7x - 11 = 2x + 44

This is the equation we will use to solve for x

7x - 11 = 2x + 44

step 1 add 44 to each side

44 + 11 = 55

-11 + 11 cancels out

we now have 7x = 2x + 55

step 2 subtract 2x from each side

7x - 2x = 5x

2x - 2x cancels out

we now have 5x = 55

step 3 divide each side by 5

5x / 5  = x

55 / 5 = 11

we're left with x = 11

The question is asking for the measure of ∠CBA

To find the measure of ∠CBA we plug in 11 for x in one of the given expressions and multiply that by 2 ( this is because the two angles are identical so there is no need to find the measures of both because ∠CBD≅∠ABD )

7(11) - 11

7 * 11 = 77

77 - 11 = 66

66 * 2 = 132

Solve this problem using an equation of ratios:


85 pounds
--------------  =  ?
    1 year

I think you may have omitted some key info from this problem.  You don't say how many hives are on this farm, for example.

garri49 [273]

Answer:

226 feet

Step-by-step explanation:

264^2 + 900^2= c^2

879696= c^2

938= c

900+ 264= 1164

1164- 938= 226

I think this is right
