Answer:

1 median=60.3

2 missing number=38

Step-by-step explanation:

1 45+55+76+y+88+54/6

316+y/6=63.6

316+x381.6

x=381.6-316=65.6

2M4 =63

60-62+92+x/4=63

214+x=252

x=252-214

=38

Y is inversely proportional to V1+x.<br> When x = 8, y = 2.<br> Find y when x = 15.

murzikaleks [220]

Answer:

y = 1.5

Step-by-step explanation:

Given x is inversely proportional to $\sqrt{1+x}$ , then the equation relating them is

y = $\frac{k}{\sqrt{1+x} }$ ← k is the constant of proportion

To find k use the condition when x = 8, y = 2

2 = $\frac{k}{\sqrt{1+8} }$ = $\frac{k}{\sqrt{9} }$ = $\frac{k}{3}$ ( multiply both sides by 3 )

6 = k

y = $\frac{6}{\sqrt{1+x} }$ ← equation of proportion

When x = 15 , then

y = $\frac{6}{\sqrt{1+15} }$ = $\frac{6}{\sqrt{16} }$ = $\frac{6}{4}$ = $\frac{3}{2}$ = 1.5

CIRCLE question is in the picture

Dennis_Churaev [7]

Answer:

27π cm² or 84.8 cm²

Explanation:

$\sf Formula \ for \ area \ of \ sector = \dfrac{\theta}{360 } \ x \ \pi (radius)^2$

Shaded region angle: 360° - 90° = 270°

Given radius: 6 cm

Applying formula:

$\rightarrow \sf \dfrac{270}{360} \ x \ \pi (6)^2$

$\rightarrow \sf 27\pi$

$\rightarrow \sf 84.823 \ cm^2$

$\rightarrow \sf 84.8 \ cm^2 \quad (rounded \ to \ nearest \ tenth)$

Let x = -11/8 and y = -11/4 Which expression has a negative value? A. x + y B. x - y C. x . y D. x/y

Mars2501 [29]

The correct answer is A

-11/8 + (-11/4)
= -11/8 - 11/4
= -11/8 - 22/8
= -33/8
