e hypothesis are as follows:H0:m0:5vs.H1:m>0:5. Suppose that the null hypothesis is not rejected and that thereal truth is th

Pani-rosa [81]

Answer:

The null hypothesis is not rejected and hence Type II error occurred

Step-by-step explanation:

Here

The null hypothesis is as follows

H0 = Mean = 0.5

The alternate hypothesis is as follows -

H1 = Mean >0.5

For Type I error = The Null hypothesis is rejected if null hypothesis is actually true

Type II error =The Null hypothesis is not rejected when the null hypothesis is not true but is false.

Here, the null hypothesis is not rejected and hence Type II error occurred

Consider the equation 3x + 90 + 2x = 360 how do we solve this?

Ivahew [28]

Answer:

Step-by-step explanation:

First add like terms: 5x+90=360

Then subtract 90 from both sides: 5x=270

Then divide both sides by 5: x=54

if a cone-shaped hole is 3 feet deep and the circumference of the base of the hole is 44 ft, what is the volume of the hole? use

Ymorist [56]

To find the volume of the whole, you will use the formula for finding the volume of a cone. V = 1/3 x r^2 x h.

You will first need to find the radius by using the information given about the circumference and the circumference formula.

C = pi x d
44 = 22/7 d
d = 14 feet.

Then use the diameter to find the radius of 7 feet.

V = 1/3 x r^2 x h
1/3 x 7^2 x 3
V = 49 cubic feet

Find the area of the irregular figure.

Diano4ka-milaya [45]

Answer:

The area of the irregular figure is 366 cm sq.

Step-by-step explanation:

This irregular figure is made of 1 Rectangle + 1 right Triangle

<u>Area of the Rectangle:</u>

Length of the rectangle = 21 cm,

Width of the rectangle = 14 cm

AREA of Rectangle = LENGTH x WIDTH

= 21 cm x 14 cm = 294 sq cm

⇒Area of the Rectangle = 294 sq cm ..... (1)

<u>Area of the Right Triangle:</u>

Base of the rectangle = 16 cm,

Height of the rectangle = 21 cm - 12 cm = 9 cm

AREA of Right Triangle = $\frac{1}{2} \times B \times H$

$= \frac{1}{2} \times 16 \times 9 = 72$

⇒Area of the Right Triangle = 72 sq cm ..... (2)

Now, area of the irregular figure = Area of the( Rectangle +Right Triangle)

= 294 sq cm + 72 sq cm = 366 cm sq

Hence, the area of the irregular figure is 366 cm sq.
