Complete Question

Let x be a continuous random variable that follows a normal distribution with a mean of 550 and a standard deviation of 75.

a

Find the value of x so that the area under the normal curve to the left of x is .0250.

b

Find the value of x so that the area under the normal curve to the right ot x is .9345.

Answer:

a

  [tex]x = 403[/tex]

b

 [tex]x = 436.75[/tex]

Step-by-step explanation:

From the question we are told that

   The  mean is  [tex]\mu = 550[/tex]

   The standard deviation is  [tex]\sigma = 75[/tex]

Generally the value of x so that the area under the normal curve to the left of x is 0.0250 is mathematically represented as

     [tex]P( X < x) = P( \frac{x - \mu }{ \sigma} < \frac{x - 550 }{75 } ) = 0.0250[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P( X < x) = P( Z < z ) = 0.0250[/tex]

Generally the critical value of  0.0250 to the left  is  

       [tex]z = -1.96[/tex]

=>    [tex]\frac{x- 550 }{75} = -1.96[/tex]

=>    [tex]x = [-1.96 * 75 ]+ 550[/tex]      

=>    [tex]x = 403[/tex]

Generally  the value of x so that the area under the normal curve to the right of x is 0.9345 is mathematically represented as

        [tex]P( X < x) = P( \frac{x - \mu }{ \sigma} < \frac{x - 550 }{75 } ) = 0.9345[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P( X < x) = P( Z < z ) = 0.9345[/tex]

Generally the critical value of  0.9345 to the right  is  

       [tex]z = -1.51[/tex]

=>    [tex]\frac{x- 550 }{75} = -1.51[/tex]

=>    [tex]x = [-1.51 * 75 ]+ 550[/tex]      

=>    [tex]x = 436.75[/tex]

Answer:

The spinning swings will have 10 more riders each hour.

Step-by-step explanation:

1. If 25 riders ride the race car every 30 mins, that would mean each hour 50 riders ride the race car.

2. If 20 riders ride the spinning swings every 20 mins, that would mean each hour 60 riders ride the spinning swings.

Lets say 4 hours have passed. We could say 25 × 8. I don't know if this would make sense but there would be 8 30 mins in 4 hours. If you multiply 25 × 8 you would get 200 riders riding the race cars in 4 hours.

Lets do the same thing with the spinning swings. There are 12 20 mins in 4 hours. So we could do could do 20 × 12. That would equal 240 riders riding the spinning swings in 4 hours.

So if the race cars got 200 riders in 4 hours, each hours they will have 50 riders. And If the spinning swings got 240 riders in 4 hours, each hour they got 60 riders. So that would mean the spinning swings got more riders each hour. They also got 10 more riders each hour. Hopefully I didn't confused you.

Answer:

The tank's capacity is 500 liters

Step-by-step explanation:

Proportions

The tank initially contains 50 liters of water. The tank's capacity is more than that, as we'll show later.

We know after 20 minutes of leaking from the tank, 40 liters still remain. This means 10 liters have leaked in 20 minutes. The loss of water occurs at a constant rate or 10/20=0.5 liters per minute.

After 30 more minutes, the tank has lost 0.5*30 = 15 more liters of water and now has 40 - 15 = 25 liters remaining.

We are told those 25 liters correspond to 5% of the tank's full capacity. Thus, the full capacity of the tank is:

[tex]\displaystyle \frac{25 }{ (5 / 100)} = 500~liters[/tex]

The tank's capacity is 500 liters

You multiply 1.43 by 10 to get 14.3. Then you multiply 14.3 by itself 9 times. Hope this helps!

Answer: 12.85

Step-by-step explanation: If you start off by multiplying them then. You'd get 225=20x-2. So from there you subtract the 2, to isolate the 20x. Then divide bother sides by 20 to get 12.85.

Answer:

w = 50

Step-by-step explanation:

−w /20  = −2.5

Step 1: Simplify both sides of the equation.

−1 /20 w = −2.5

Step 2: Multiply both sides by 20/(-1).

( 20/ −1 ) * ( −1/ 20 w) = ( 20 /-1 ) * (−2.5)

w = 50

Answer:

Please check the explanation!

Step-by-step explanation:

Given the polynomial

[tex]\left(x+y\right)^5[/tex]

[tex]\mathrm{Apply\:binomial\:theorem}:\quad \left(a+b\right)^n=\sum _{i=0}^n\binom{n}{i}a^{\left(n-i\right)}b^i[/tex]

[tex]a=x,\:\:b=y[/tex]

[tex]=\sum _{i=0}^5\binom{5}{i}x^{\left(5-i\right)}y^i[/tex]

so expanding summation

[tex]=\frac{5!}{0!\left(5-0\right)!}x^5y^0+\frac{5!}{1!\left(5-1\right)!}x^4y^1+\frac{5!}{2!\left(5-2\right)!}x^3y^2+\frac{5!}{3!\left(5-3\right)!}x^2y^3+\frac{5!}{4!\left(5-4\right)!}x^1y^4+\frac{5!}{5!\left(5-5\right)!}x^0y^5[/tex]

solving

[tex]\frac{5!}{0!\left(5-0\right)!}x^5y^0[/tex]

[tex]=1\cdot \frac{5!}{0!\left(5-0\right)!}x^5[/tex]

[tex]=1\cdot \:1\cdot \:x^5[/tex]

[tex]=x^5[/tex]

also solving

[tex]=\frac{5!}{1!\left(5-1\right)!}x^4y[/tex]

[tex]=\frac{5}{1!}x^4y[/tex]

[tex]=\frac{5}{1!}x^4y[/tex]

[tex]=\frac{5x^4y}{1}[/tex]

[tex]=\frac{5x^4y}{1}[/tex]

[tex]=5x^4y[/tex]

similarly, the result of the remaining terms can be solved such as

[tex]\frac{5!}{2!\left(5-2\right)!}x^3y^2=10x^3y^2[/tex]

[tex]\frac{5!}{3!\left(5-3\right)!}x^2y^3=10x^2y^3[/tex]

[tex]\frac{5!}{4!\left(5-4\right)!}x^1y^4=5xy^4[/tex]

[tex]\frac{5!}{5!\left(5-5\right)!}x^0y^5=y^5[/tex]

so substituting all the solved results in the expression

[tex]=\frac{5!}{0!\left(5-0\right)!}x^5y^0+\frac{5!}{1!\left(5-1\right)!}x^4y^1+\frac{5!}{2!\left(5-2\right)!}x^3y^2+\frac{5!}{3!\left(5-3\right)!}x^2y^3+\frac{5!}{4!\left(5-4\right)!}x^1y^4+\frac{5!}{5!\left(5-5\right)!}x^0y^5[/tex]

[tex]=x^5+5x^4y+10x^3y^2+10x^2y^3+5xy^4+y^5[/tex]

Therefore,

[tex]\left(x\:+y\right)^5=x^5+5x^4y+10x^3y^2+10x^2y^3+5xy^4+y^5[/tex]

Answer:

19

Step-by-step explanation:

Is he stop every 1/4 mile you get 19

There are 4 1/4 miles in every mile. 4x4(Equation of total 1/4th's in 4 miles) is 16. Add 3 more 1/4th's to get 19

Hope this helps!

Total number of rest is 19 times

Given that;

Distance walked by Ricky = 4³/₄ miles = 19 / 4 miles

rest on every mile = 1/4 miles

Find:

Total number of rest

Computation:

Total number of rest = Distance walked by Ricky ÷ Rest on every mile

Total number of rest = [19 / 4] ÷ [1 / 4]

Total number of rest = 19 times

Answer:

The value is [tex]\mu_{x} = 5.6 \ years[/tex]

Step-by-step explanation:

From the question we are told that

   The population mean is  [tex]\mu = 5.6 \ years[/tex]

    The standard deviation is  [tex]\sigma = 0.9 \ years[/tex]

    The sample size is  n  =  49  

Generally given that the sample size is large enough, the  sampling distribution created using the samples of the ages at which 49 children begin reading is equal to the population mean

i.e

     [tex]\mu_{x} = \mu[/tex]

=>  [tex]\mu_{x} = 5.6 \ years[/tex]
