Answer:

Step-by-step explanation:

Distance = 3 2/5 miles = $\frac{17}{5} \ miles$

Time taken = 2/3 hour

$Speed =\dfrac{distance}{time}$

= $\frac{17}{5}$ ÷ $\frac{2}{3}$

$=\dfrac{17}{5}*\dfrac{3}{2}=\dfrac{51}{10}=5\dfrac{1}{10} \ miles \ per \ hour$

The radius of the base is 10 cm.

Solution:

Height of a cone = 15 cm

Volume of the cone = 1570 cm³

To find the radius of the base of the cone:

Volume of the cone = $\frac{1}{3}\pi r^2 h$

$$\Rightarrow \frac{1}{3}\pi r^2 h=1570$

$$\Rightarrow \frac{1}{3}\times\ 3.14\times r^2 \times 15=1570$

$$\Rightarrow\ 3.14\times r^2 \times 5=1570$

$$\Rightarrow\ 15.7\times r^2 =1570$

Divide by 15.7 on both side of the equation, we get

$$\Rightarrow r^2 =100$

Taking square root on both sides of the equation, we get

⇒ r = 10

Hence the radius of the base is 10 cm.

If a histogram is right skewed, which will be greater the mean or the median? Type a single word answer in the space

Mandarinka [93]

Answer:

Mean is greater

Step-by-step explanation:

For a skewed distribution, then the tail is longer to one side from the center than to the other. In a right skewed distribution, the tail is longer to the right.

When a distribution is skewed, the mean will be closer to the tail Than the median. Therefore. For a right skewed histogram, the mean is closer to the tail of the histogram and hence closer to the right. Once this happens, values closer to the right of a distribution are higher (number line). Thus the mean will be greater than the median.
