Answer:

Option D) 1.26 tons

Step-by-step explanation:

we have

d=\frac{10w}{\pi}

where

d is the diameter of a rope in inches

w is the weight in tons

we have

d=2(2)=4\ in ----> the diameter is two times the radius

substitute the value of d and solve for w

4=\frac{10w}{\pi}

w=\frac{4\pi}{10}=0.4\pi\ tons

assume

\pi =3.14

0.4(3.14)=1.26\ tons

krek1111 [17]

<u>Answer:</u>

Events A and B are not independent because P(A|B) ≠ P(A).

<u>Step-by-step explanation:</u>

We are given that the probability of a student scoring 75% in class work is 0.64, and the probability of a student scoring 85% is 0.45.

Given that a student scores 85%, it means he must have scored 75% too.

It means that event B is dependent on event A.

Therefore, events A and B are not independent because P(A|B) ≠ P(A).

A large concrete block is used for the cornerstone
marin [14]

Answer:

The volume of the concrete needed to make the block is 5054 ft³

Step-by-step explanation:

The question relate to the calculation of the volume of a shape

The dimensions of the block are;

The depth of the block, d = 19 ft.

The width of the block, w = 19 ft.

The length of the block, l = 14 ft.

The volume of a cube, V = Length, l × Width, w × Depth, d

Therefore, the volume, 'V' of a cubic block is given as follows;

V = l × w × d = 14 ft. × 19 ft. × 19 ft. = 5054 ft.³

The volume of the concrete needed to make the block = The volume of the block, V = 5054 ft³.
