Answer:

woven blanket

Step-by-step explanation:

(a) The proportion of accidents that occur up to mile 1.2 of the path is the area under the density curve between 0 miles and 1.
inn [45]

Answer:

the area would be 0.4 or 40%

Step-by-step explanation:

The computation of the area is given below:

But before that the level of the density is

The density level is

=  1 ÷ (3 - 0)

= 1 ÷ 3

Area from 0 miles to 1.2 miles

= (1 ÷ 3) × (1.2 - 0)

= 0.4 or 40 %

Hence, the area would be 0.4 or 40%

the same is considered and relevant too

The mass of Earth is 5.97 X 10²⁴ kilograms. The mass of the Moon is 7.34 x 10²² kilograms. What is the combined mass of earth.
Damm [24]

Answer:

13.31 x 10^{46}

Step-by-step explanation:

So, if we take the two equations, and add the normal numbers together, we have: 5.97 + 7.34 = 13.31

Then if we add the two tens together it would be: 10^2^2 + 10^{24 = 10 to the power of 46.

The equation would be 13.31 x 10^{46}

I'm not an expert, so sorry if this is wrong.
