Answer:

C

Step-by-step explanation:

unimodel: A unimodal distribution is a distribution with one clear peak or most frequent value. The values increase at first, rising to a single peak where they then decrease.

answer is: c

Step-by-step explanation:

"A uni-modal distribution is a distribution with one clear peak or most frequent value. The values increase at first, rising to a single peak where they then decrease.Sep 18, 2013"

both of these are correct

"A uniform distribution, sometimes also known as a rectangular distribution, is a distribution that has constant probability. The probability density function and cumulative distribution function for a continuous uniform distribution on the interval are."

Question help a robotic rover on mars finds a spherical rock with a diameter of 1313 centimeters. the rover picks up the rock an
KengaRu [80]
Due to apparent doubling of numbers in the question, assume
diameter=13 cm/2=0.065m
h=15 cm=0.15m
rho=5.25*1000=5250 kg/m^3
eta=35%=0.35 [efficiency]
t=12 s
g=3.7 m/s^2

mass, m=rho*V=rho*(4pi/3)(r^3)
=5250 kg/m^3 * (4pi/3)(0.065)^3 m^3
=1.922 kg

Work done in lifting h=0.15m
W=mgh
=1.922pi kg * 3.7 m/s^2 * 0.15 m
=1.067pi kg (m/s)^2
=1.067pi J

Average power required, with efficiency eta=0.35
P=(W/t)/eta
=(1.067pi J )/ (12 s) /0.35
=0.254pi J/s
=0.798W (approx.)

Peanuts sell for $3 per pound. Cashews sell for $6 per pound. How many pounds of cashews should be mixed with 12 pounds of peanu
Phantasy [73]

Answer:

84

Step-by-step explanation:

12*3+6x=4.20(12+x)

36+6x=50.4+4.2x

6x-4.2x=50.4-36

1.8x=14.4

x=14.4/1.8

x=8 pounds of cashews is used.

Proof:

12*3+6*8=4.2(12+8)

36+48=4.2*20

84=84

You have 0.2 liter of an acid solution whose acid concentration is 16 moles per liter. You want to dilute the solution with wate
hram777 [196]

Answer: 0.067 litres of water

Step-by-step explanation:

The mode is:

Concentration of new solution = Moles of acid in original solution / (Volume of original solution + Volume of water added)

Assume volume of water added is w.

12 = 16 (0.2) / (0.2 + w)

(0.2 + w) * 12 = 3.2

0.2 + w = 3.2 / 12

w = (3.2 / 12) - 0.2

w = 0.067 litres of water
