Jose be concerned that the spinner is unfair? Explain.

B. Jose spins the spinner 500 times. In those 500 spins, the arrow lands on 3 a total of 42 times. Based on this
information, should Jose be concerned that the spinner is unfair? Explain.

Answer 1

Answer: B. Jose spins the spinner 500 times. In those 500 spins, the arrow lands on 3 a total of 42 times. Based on this information, should Jose be concerned that the spinner is unfair? Explain.Yes the spinner is begin unfair again he has a 25% chance to get the 3 if you multiply 25% by 500 you get 125 if you divide 125 by 500 it equals 25% again so if 42/500 equals 8.4% you know something has to be wrong

Find f(-11/5) if f(n) = 5n + 6.. A) -17. B) 5. C) -6

Answers

$f(n)=5n+6\n\nf\left(-(11)/(5)\right)=?\n\nsubtitute\ n=-(11)/(5)\ to\ the\ equation:\n\nf\left(-(11)/(5)\right)=5\cdot\left(-(11)/(5)\right)+6=-11+6=-5$

f(-11/5)=5(-11/5)+6
f(-11/5) = -11+6
f(-11/5) = -5 so option B is correct

the sum of two numbers is 44. the smaller number is 20 less than the larger number. what are the numbers?

Answers

sum means add
x and y are the numbers
sum i 44
x+y=44

smaller s 20 les than larger
x=20+y
or
y=20+x
doesn't matter, just pick one
x=20+y

substue 20+y for x since they are equal
x+y=44
(20+y)+y=44
20+y+y=44
20+2y=44
subtract 20 from both sides
2y=24
divide by 2
y=12
subsitue
x=20+y
x=20+12
x=32

the numbers are 12 and 32

x+(x-20)=44
2x= 64
x=32

Therefore the bigger number is 32 and the smaller number is 12
32+12=44

The mean sustained wind velocity, v, can be determined by the equation v = 6.3 StartRoot 1013 minus p EndRoot, where p is the air pressure, in millibars, at the center of the hurricane. What is the approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second?

Answers

Answer:

909.8 millibars.

Step-by-step explanation:

The mean sustained velocity, v be determined by the equation:

$v=6.3√(1013-p)$ , where p is the air pressure, in millibars, at the center of the hurricane.

Given that: v=64 meters per second, we are to find the value of p.

$64=6.3√(1013-p)\n$Square both sides to eliminate the square root sign\n(64)^2=(6.3√(1013-p))^2\n4096=39.69(1013-p)\n$Divide both sides by 39.69$\n(4096)/(39.69)=1013-p\n $Therefore:$\np=1013-(4096)/(39.69)\n\np=909.8$ millibars$

The approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second is 909.8 millibars.
