Answer:
Part A: (1/2)m
Part B: (1/3rd)b and 3mx
Step-by-step explanation:
Price of each baseball is=$m
Price of other equipment are=$b collectively
Total amount He spent on purchasing equipment is =(m+b)$
Part A:
in part A the amount on purchasing other equipment than baseball is getting doubled i.e. $2b <u> then value of m will be (1/2)half of the total amount spent on purchasing baseball i.e. (1/2)m</u>
Part B:
in part B the amount spent on purchasing baseball is getting tripled i.e. <u>3m</u>, then value of b(amount of purchasing other equipment) is<u> (1/3rd) of total</u> <u>amount spent on purchasing other equipment</u> and value of mx will be<u> 3mx</u>
Answer:
Multiply the length times the width
Step-by-step explanation:
First one finds diameter, third one finds diameter, and fourth one finds triangle. The second one finds the area of a rectangle.
Answer:
±sqrt(T*L/m)=v
Step-by-step explanation:
T=mv^2/L
We want to solve the equation for v
Multiply each side by L
T*L=mv^2/L
*L
T*L=mv^2
Divide each side by m
TL/m=mv^2/m
T*L/m=v^2
Take the square root of each side
±sqrt(T*L/m)=sqrt(v^2)
±sqrt(T*L/m)=v
Answer:Positive
Step-by-step explanation:
I just answerEd it
Mean is 
and a standard deviation is 
, then the variable 
.
Use substitution
.
This substitution gives you that 
.
a. For X=130, 
and 
(the decimal value is taken from the Standard Normal Distribution Table).
b. For X=90, 
and for X=110, 
. Then 
(the decimal value is taken from the Standard Normal Distribution Table).
