Answer:

area of triangle = 4.5*6/2 = 13.5 sq.yd.

Step-by-step explanation:

The area of a right triangle is half of the product of the sides adjacent to the right angle.

Here the sides adjacent to the right angle are 6 yd and 4.5 yd.

Therefore the

area of triangle = 4.5*6/2 = 13.5 sq.yd.

What is the volume of the figure

Rufina [12.5K]

Answer:

2411.52 cm³

Step-by-step explanation:

V = (2/3)πr³ Use the equation for volume of a hemisphere

V = (2/3)(3.14)(8)³ Simplify the exponent

V = (2/3)(3.14)(512) Multiply

V = 1071.79 cm³

V = πr² h/3 Now find the volume of the cone

V = (3.14)(8)²(20/3) Simplify the exponent

V = (3.14)(64)(20/3) Multiply

V = 1339.73 cm³

Add both of the volumes together to get the volume of the figure.

1071.79 + 1339.73 = 2411.52 cm³

Doing research for insurance rates, it is found that those aged 30 to 49 drive an average of 38.7 miles per day with a standard

Alja [10]

Answer: 0.4302

Step-by-step explanation:

Given : Mean : $\mu=\text{38.7 miles }$

Standard deviation : $\sigma=\text{6.7 miles }$

Sample size : $n=60$

Also, these distances are normally distributed.

Then , the formula to calculate the z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x=32.5

$\\\\ z=\dfrac{32.5-38.7}{6.7}=-0.925373134\approx-0.93$

For x=40.5

$\\\\ z=\dfrac{40.5-38.7}{6.7}=0.268656\approx0.27$

The p-value = $P(-0.93$

$=P(0.27)-P(-0.93)=0.6064198- 0.1761855=0.4302343\approx0.4302$

Hence, the required probability :-0.4302
