If x2 - 6x - 16, what are the x-intercepts?​

Answer: a) 25%

b) 75% Chebyshev interval around the sample mean=(6,18)

Step-by-step explanation:

Given: Sample mean: [tex]\overline{x}=12[/tex]

Sample standard deviation: s= 3

a) Coefficient of variation = [tex]\dfrac{s}{\overline{x}}\times100[/tex]

[tex]\\\\=\dfrac{3}{12}\times100\%=\dfrac{100\%}{4}\\\\=25\%[/tex]

b) According to the Chebychev's theorem,

75% of the population lies within 2 standard deviations from the sample mean.

i.e. 75% Chebyshev interval around the sample mean. = [tex](\overline{x}-2s,\ \overline{x}+2s)[/tex]

[tex]=(12-2(3),\ 12+2(3))\\\\=(6, 18)[/tex]

Hence, the 75% Chebyshev interval around the sample mean=(6,18)

Each aquarium has 170 liters of water in it.

Step-by-step explanation:

To get this, you need to divided 850 by 5 to get the amount of water in each tank to make sure that it is all equally distributed. This way we now know that each tank needs 170 liters of water to have an equal amount of water in each tank

Answer: c

Step-by-step explanation:

Answer:

C. y </ 3/4x +10 and y<l -1/2x - 3

Step-by-step explanation:

Basically first do process of elimination with your focus on one equation

for example :: ( >l is greater then or equal to and <l is lease then or equal to)

focus -> y >l 3/4x + 10

1) determine which line has the y-intercept of positive 10

2) is the line dotted or straight? dotted line = > or < while straight line = >l or <l

this should get rid of B and D now

3) remember this = if the slope is - then the shaded portion would be the way that the less then sign is pointing

( y <l -4x then the shaded portion would be on the left side )

remember again = if the slope is + then the shaded portion would be the way that the greater then sign is pointing

( y <l 4x then the shaded portion would be on the right side )

so the line that we are focused on would have the right side shaded which means that it would be a <l ,so the answer would be C

hope this helped you understand how to solve these a bit better!

(tbh the day I figured how to solve these problems, I swear the whole world turned 180 degrees for me. )

Answer:

45 degrees

Step-by-step explanation:

if <9 and <10 are corresponding, it means they are equal i.e <9 = <10

Since <9 and <10 are also complementary angles, their sum will be 90 degrees

<9+<10 = 90

<9 + <9 = 90

2m<9 = 90

m<2 = 90/2

m<2 = 45 degrees

Hence the measure of angle 9 is 45 degrees

Step-by-step explanation:

f(2) = -2^2 + 2 + 14 = -4 + 2 + 14 = 12

Answer:

f(2) = 20

Step-by-step explanation:

f(x) = -x^2 + x + 14

f(2) = (2)^2 + (2) + 14

f(2) = 4 + 2 + 14

f(2) = 20

Answer:

12/15 or .8

Step-by-step explanation:

So first you divide both the numerator and denominator by 2 because it’s the biggest number that goes into both 24 and 30

24 and 30 simplified by 2 gives us 12 and 15

you can’t simplify any further so your answer is 12/15

If you want a decimal, then you divide 24 by 30 and your answer is .8

Answer:

x=-3

Step-by-step explanation:

Because its straight, on the x-axis, and on -3.

===========================================================

Explanation:

This green line goes through -3 on the x axis. Every point on this line has the same x coordinate and that x coordinate is x = -3. For instance, the two points (-3,5) and (-3,2) are on this green line. The equation of this line is x = -3 to indicate that x must be -3, but y can be anything you want. So that's why the y term doesn't even show up here. We cannot write the equation into slope intercept form. The slope of any vertical line is undefined.

Answer:

in triangle ABD

x+6+2x-3+90=180(sum of interior angle of triangle) (since each angle of rectangle=90)

3x+3=180-90

3x=90-3

x=87/3=29°

<DBC=<ADB{ALTERNATE ANGLE)=2x-3=2×29-3=55°

<BDC=ABD(ALTERNATE ANGLE)=x+6=29+6=35°

<ADH=180-<ADB{LINEAR PAIR)=180-2x-3=180-2×29-3=180-58-3=119°

<EBG=<DBC(VERTICALLY OPPOSITE ANGLE)=55°

Answer:

c = 4

Step-by-step explanation:

6c = 24

(divide 6 by each number to get eh variable by itself)

6c = 24

/6    /6

c = 4

To check work:

insert 4 for c into equation

6(4) = 24

24 = 24
