Answer:

Yes, they vary directly

Step-by-step explanation:

y=kx; k is the constant (12 in this case) and as x increases y increases, so they vary directly

When the outliers are removed, how does the mean change?

jok3333 [9.3K]

In statistics, an outlier is an observation point that is distant from other observations.

Given the points
15, 23, 24, 26, 27 and 35

Notice, that the points 15 and 35 are distance from the other points and hence are outliers.

The mean of the observations including the outliers is given by
$\frac{15+23+24+26+27+35}{6} = \frac{150}{6} =25$

The mean of the observations without the outliers is given by
$\frac{23+24+26+27}{4} = \frac{100}{4} =25$

Therefore, when the outliers are removed, the mean remains the same.

Can anybody explain how I answer this question I really don't get trig equations

nasty-shy [4]

SinØ(TanØ+2)=3cosØ -----[pulling like terms out]

for the following steps The easiest 4 me is that I just plug in values between 0° and 180° for Ø and see which will help me to get equal numbers on both sides.

So, for instance if you use Ø=90°, you'll get the following, Sin90(Tan90+2)=3cos90

========> 1(1+2)=3(1) ==> 3=3

so 90° is one of the solutions ur looking for.

hope this was helpful

Find the area of the shaded region. (You may express your answer in terms of π.)

erastova [34]

Answer:

a. 16π cm²

b. 24π cm²

c. 33 1/3π cm²

d. 64π-128 cm²

e. 144π-288 cm²

Step-by-step explanation:

To find area of shaded region, find area of whole circle then divide the area where you're left with the area of the shaded region. For the problems with the triangles you find the area of the triangle then subtract that from a fourth of the area of the circle.

Area of a circle = πr²

r=8cm

Area of circle=64π cm²

Shaded region=16π cm²

r=12cm

Area of circle=144π cm²

Shaded region=24π cm²

r=10cm

Area of circle=100π cm²

Shaded region=33 1/3π cm²

r=16cm

Area of circle=256π cm²

Area of triangle=128 cm²

Shaded region=64π-128 cm²

r=24

Area of circle=576π cm²

Area of triangle=288 cm²

Shaded region=144π-288 cm²

solve for x in the rhombus sin(42)= x/50

Hunter-Best [27]

Answer:

x = 33.45

Step-by-step explanation:

We need to find the value of x in the given expression i.e.

$\sin(42)=\dfrac{x}{50}$

Multiplying both sides by 50. So

$\sin(42)\times 50=\dfrac{x}{50}\times 50\\\\x=\sin(42)\times 50\\\\x=33.45$

So, the value of x is equal to 33.45.
