The frequency distribution shows the number of registered motor vehicles for a random sample of 200 California households.

erastovalidia [21]

Answer:

1). Mean = 2.275

2). Median = 2 vehicles

Step-by-step explanation:

From the given table,

Number of vehicles (x) Frequency (f) (f)×(x) Cumulative freq.

0 11 0 11

1 52 52 63

2 66 132 129

3 35 105 164

4 19 76 183

5 12 60 195

6 5 30 200

$\sum (f\times x) = 455$

Number of households = 200

Mean = $\sum \frac{f.x}{n}$

= $\frac{455}{200}$

= 2.275

Median = value of $\frac{(n+1)}{2}th$ observation

= value of $\frac{201}{2}th$ observation

= Value of 100.5th observation

= Since 100.5th observation lies in the row of cumulative freq. = 129

= 2

Therefore, median number of registered vehicles per California household

= 2 vehicles

For a circle with a diameter of 6 meters, what is the measurement of a central angle (in degrees) subtended by an arc with a len

Sholpan [36]

Answer:

$\boxed{\boxed{\theta=150^{\circ}}}$

Step-by-step explanation:

We know that,

$\text{Arc length}=r\cdot \theta$

where,

r = radius,

θ = central angle in radian.

Given,

diameter = 6 m, so radius = 3 m.

$\text{Arc length}=\dfrac{5}{2}\pi$

Putting the values,

$\Rightarrow \dfrac{5}{2}\pi=3\theta$

$\Rightarrow \theta=\dfrac{5}{2\times 3}\pi$

$\Rightarrow \theta=\dfrac{5}{6}\pi=\dfrac{5}{6}\times 180^{\circ}=150^{\circ}$

M×10-m×2=8 fill in the blanks as m

son4ous [18]

M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8

Fill in the m's:
1*10-1*2=8
10-2=8
8=8

Hope this helps :)
