1. The mean annual US household income is $72,641. Suppose that the standard deviation is $30,000. a. Find the probability that a household chosen at random has an income greater than $100,000. b. Find the probability that a group of 5 households, chosen at random, have an average income greater than $100,000. c. Find the probability that a group of 10 households, chosen at random, have an average income greater than $100,000.
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given as:
[tex]z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score,\mu=mean\ and\ \sigma=standard\ deviation \\\\For\ a\ sample\ size\ n: \\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }[/tex]
Given that μ = $72,641 and σ = $30,000.
a) x > $100000
[tex]z=\frac{100000-72641}{30000}=0.91[/tex]
P(x > 100000) = P(z > 0.91) = 1 - 0.8186 = 0.1814
b) n = 5
x > $100000
[tex]z=\frac{100000-72641}{30000/\sqrt{5} }=2.04[/tex]
P(x > 100000) = P(z > 2.04) = 1 - 0.9793 = 0.0207
c) n = 10
x > $100000
[tex]z=\frac{100000-72641}{30000/\sqrt{10} }=2.88[/tex]
P(x > 100000) = P(z > 2.88) = 1 - 0.9980 = 0.002
y = 1/6x + 8 Identify the slope?
Answer:
The slope is 1/6
Step-by-step explanation:
The equation is written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept.
From this, we know that 1/6 is the slope because it is plugged in for m.
Hope this helps! :)
Answer:
The slope is 1/6
Explanation:
The slope is always the coefficient of X

A polynomial p has zeros when x=5, x=-1, and x=-1/4. what could be the equation of p?
A. p(x)=(x+5)(x+1)(4x+1)
B. p(x)=(x-5)(x+1)(4x+1)
C. p(x)=(x+5)(x-1)(4x-1)
D. p(x)=(5x)(-1x)(-1/4x)
Answer:
B

Given: x = 5 ; x - 5=0
x = -1; x+ 1= 0
x = -1/4; 4x + 1 = 0
Then; (x - 5)(x + 1)(4x + 1)

Find the value of c so that the polynomial p is divisible by (x+2)
Answer:
The value of c is 8.
Step-by-step explanation:
When a function is divisible by a factor, it will get 0 value. So, you have to substitute x = -2 into p(x) and equals to 0 :
[tex]p(x) = 4 {x}^{3} + c {x}^{2} + x + 2[/tex]
[tex]p( - 2) = 4 {( - 2)}^{3} + c {( - 2)}^{2} + ( - 2) + 2[/tex]
[tex]4( - 8) + 4c - 2 + 2 = 0[/tex]
[tex] - 32 + 4c = 0[/tex]
[tex]4c = 32[/tex]
[tex]c = 32 \div 4[/tex]
[tex]c = 8[/tex]

The probability of waiting 2 minutes or longer for checkout at a particular supermarket counter is 0.3. On a given day, a man and his wife decide to shop individually at the market, each checking out at different counters. They both reach the counters at the same time. What is the probability that one or the other or both will wait 2 minutes or longer?
Answer:
The probability answer is 69/100
Step-by-step explanation:
The probability of waiting 2 minutes or longer = 0.3= (3/10)
The probability of not waiting longer = 1 - (3/10) = (7/10)
For the man,
P(waiting 2 mins or longer) = 3/10
For the woman,
P(waiting 2 mins or longer) = 3/10
Therefore,
The probability that one or the other or both will wait 2 minutes or longer
= P(man waits 2 mins or longer) or P(woman waits 2 mins or longer) or P(both waits 2 mins or longer)
= (3/10) or (3/10) or ( (3/10) and (3/10) )
= (3/10) + (3/10) + ( (3/10) X (3/10) )
= (6/10) + (9/100)
= (69/100)

Complete the proof of the identity by choosing the Rule that justifies each step.
(1- cos x) so
secx sin tan
To see a detailed description of a Rule, select the More Information Button to the right of the Rule,
( 1 - cos²x ) secx
=> sin²x . secx
Here the rule ( rule 1 ) is the first trigonometric identity [ sin²A + cos²A = 1 ] by simplifying we have , [ 1 - cos²A = sin² ] . So here we substituted 1 - cos²x = sin²x .
=> sin²x [ 1/cosx ]
Here the rule ( rule 2 ) is secx = 1/cosx . So here we substituted secx = 1/cosx .
=> sinx [ sinx/cosx ]
Here the rule ( rule 3 ) is sin²x can be written as sinx . sinx , so we get sinx . sinx [ 1/cosx ] next by simplifying , sinx [ sinx/cosx ].
=> sinx tanx
Here the rule ( rule 4 ) is , in the above we got sinx/cosx and here we know that , sinx/cosx = tanx . So we have tan x .
The proof of the identity that justifies that ( 1 - cos²x ) secx equals sinx(tanx) has been described below with statements and rules.
Statement 1; ( 1 - cos²x ) secx
This is given
Statement 2; sin²x · secx
Rule 1; From trigonometric identities, we know that;
sin²x + cos²x = 1,
Thus; cos²x = 1 - sin²x
Thus; ( 1 - cos²x ) secx = sin²x · secx
Statement 3; sin²x (1/cosx)
Rule 2; The rule here according to trigionometric identities is that; secx = 1/cosx. Thus; secx = 1/cosx .
Statement 4; sinx (sinx/cosx )
Rule 3; The rule here is that sin²x can be expressed as (sinx * sinx)
Thus, we have; sinx . sinx (1/cosx) = sinx (sinx/cosx ).
Statement 5; sinx(tanx)
Rule 4; The rule here is that; sinx/cosx = tanx.
Thus; sinx (sinx/cosx ) gives us sinx(tanx)

Kiran and Clare live 24 miles away from each other along a rail trail. One Saturday, the two friends started walking toward each other along the trail at 8:00 a.m. with a plan to have a picnic when they meet.
Kiran walks at a speed of 3 miles per hour while Clare walks 3.4 miles per hour.
e) After one hour, how far apart will they be?
Answer:
17.6 miles
Step-by-step explanation:
speed = distance/time
distance = speed * time
We multiply the speed of each one by the time, 1 hour, to find the distance each one walked in 1 hour.
Kiran: 3 mph * 1 h = 3 miles
Clare: 3.4 mph * 1 h = 3.4 miles
The total distance they walked is 3 miles + 3.4 miles = 6.4 miles.
After 1 hour, they are 6.4 miles closer than they were at the beginning of the walk.
24 miles - 6.4 miles = 17.6 miles
Answer: 17.6 miles
