housing: 900/4500 = 0.2 = 20%

transportation: 650 / 4500 = 0.14 = 14%

utilities: 120/4500 = 0.026 = 2.6% ( round to 3% maybe)

food: 475/4500 = 0.105 = 10.5% (round to 11% maybe)

savings: 1600 / 4500 = 0.355 = 35.5% (round to 36% maybe)

Student Loan: 270 / 4500 = 0.06 = 6%

Other expenses: 485 / 4500 = 0.107 = 10.7% (round to 11% maybe)



 You didn't say if they needed to be rounded so I gave you the options on the ones that may need it.

Consider the probability that more than 99 out of 157 software users will not call technical support. Assume the probability tha
Rainbow [258]

Answer:

P(x>99)= 0.468

Step-by-step explanation:

From the question we are told that:

Sample size 157

Sample mean

\=x =np

\=x =157*0.56

\=x = 87.92

Generally the equation for Standard deviation is mathematically given by

\sigma=\sqrt{npq}

\sigma=\sqrt{157*0.56*0.44}

\sigma =6.22

Therefore

P(x>99)=P(z>(\frac{99.5-87.92)}{6.22})

P(x>99)=P(z>1.86)

P(x>99)= 0.468

Ok this is kind of silly to ask but I have an equation 12-3x how do I get 3x in the front
lesantik [10]
As you can see there is a negative sign befor 3x. That means 3x is a negative value. Therefore, in order to place it as first left value you would take -3x and put it before +12 ( since there is no negative sign before 12, it will stay positive)

-3x+12

Hope This Helps :)
