Answer:
<h2> 52 chickens</h2>
Step-by-step explanation:
Step one:'
given
we are told that the total number of animals is 169
the ratio of horses to chickens= 9:4
total ratio= 13
Required:
number of chickens
Applying part to all principle, let the number of chickens be x
4/13=x/169
cross multiply
4*169=13*x
divide both sides by 13
x=4*169/13
x=676/13
x=52
There are 52 chickens
Answer:
The probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
Step-by-step explanation:
![Mean = \mu = 3.25 inches](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cmu%20%3D%203.25%20inches)
Standard deviation = ![\sigma = 0.15 inches](https://tex.z-dn.net/?f=%5Csigma%20%3D%200.15%20inches)
We are supposed to determine the probability that a randomly chosen part has diameter of 3.5 inches or more
![P(Z \geq 3.5)=1-P(z](https://tex.z-dn.net/?f=P%28Z%20%5Cgeq%203.5%29%3D1-P%28z%3C%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%29%5C%5CP%28Z%20%5Cgeq%203.5%29%3D1-P%28z%3C%5Cfrac%7B3.25-3.5%7D%7B0.15%7D%29%5C%5CP%28Z%20%5Cgeq%203.5%29%3D1-P%28z%3C-1.67%29)
Refer the z table for p value
![P(Z \geq 3.5)=1-0.0475\\P(Z \geq 3.5)=0.9525](https://tex.z-dn.net/?f=P%28Z%20%5Cgeq%203.5%29%3D1-0.0475%5C%5CP%28Z%20%5Cgeq%203.5%29%3D0.9525)
Hence the probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
Well since right now the average is 74.4, the tenth student would need to earn an 80 so the team got exactly an average of 75
Answer:
surface area is 39
Step-by-step explanation:
add the areas of each geometric figure making up the composite 3D figure.
first 3D figure
2+2+6+6
=16---eq 1
from third 3D figure
4+4+10+5
= 23
from 1 and 2
16+23
= 39
may be!! I'm not sure bout this answer
Answer:
The expression for the amount Mr. Parker will pay for the van be
x = 50 + 0.35m
Step-by-step explanation:
Let us assume that the amount Mr. Parker will pay for the van be x.
As given
Mr. Parker wants to rent a cargo van for a day.
It will cost the daily fee of $50 plus $0.35 per mile driven.
Let m = the number of miles .
Than the expression for the amount Mr. Parker will pay for the van.
x = 50 + 0.35m
Therefore the expression for the amount Mr. Parker will pay for the van be
x = 50 + 0.35m
