Hi,
The answer is 1219/3000000 Km/Hr
How I got my answer:
Convert yard to foot
3 foot=1 yard
2/3*3=2 foot
Now convert foot to km
1 foot=0.0003047 km
2 foot= 0.0003047*2
2 foot= 0.0006095 km
speed(yards can the snail crawl in 1 hour)=distance/time
speed=0.0006095/1.5 Km/Hr
speed=0.006095/15 Km/Hr
speed=0.001219/3 Km/Hr
speed=1219/3000000 Km/Hr
Hope this helps you.

yarga [219]

Solution: The total money did addison have to begin with is $29.

Explanation:

Let the addison begin with money $x.

It is given that the addison earn $25 from his neighbor and $50 from her grandmother. So total money addison has $\$x+\$25+\$50=\$x+\$75$

She loaned her friend %18.

Now she has $\$x+\$75-\$18=\$x+\$57$

It is given that she had $86.

$\$x+\$57=\$86\\\$x=\$86-\$57\\\$x=\$29$

Therefore, the total money did addison have to begin with is $29.

The heights of young women aged 20 to 29 follow approximately the N(64, 2.7) distribution. Young men the same age have heights d

murzikaleks [220]

Answer: 10.703%

Step-by-step explanation:

Let minimum height of the tallest 25% of young women be M.

Let Q be the random variable which denotes the height of young women.

Therefore, Q – N(64,2.70)

Now, P(Q˂M) = 1-0.25

i.e. P[(Q-64)/2.7 ˂ (M-64)/2.7] = 0.75

I.e. ф-1 [(M-64)/2.7] = 0.75 i.e. (M-64)/2.7 = ф-1 (0.75) = 0.675 i.e. M = 65.8198 inches

Let R be the random variable denoting the height of young men

Therefore, R – N (69.3, 2.8)

i.e. (R-69.3)/2.8 – N(0,1)

therefore the probability required = P(R ˂65.8198) = P[(R-69.3)/2.8 ˂ (65.8198 – 69.3)/2.8]

this gives P[(R-69.3)/2.8 ˂] = ф (-1.2429) = 0.107033

From this, the percentage of young men shorter than the shortest amongst the tallest 25% of young women is 10.703%
