-w/20=-2.5 help please its due today
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

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]

Step-by-step explanation:
Two natural numbers differ by 1 and add to give 35. Find the smaller number. google it and answer will come,I just need answer pls.. It is blocked on my school chromebook soo...
Answer:
17
Step-by-step explanation:
Since the numbers differ by 1, you can write the smaller number as x and the bigger one as x+1.
When you add them together you get 35: x+x+1=35
This simplifies to 2x+1=35.
When you solve you get 2x=34 so x=17.

Step-by-step explanation:
Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.6 years with a standard deviation of 0.9 years. If a sampling distribution is created using samples of the ages at which 49 children begin reading. What would be the mean of the sampling distribution?
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]

Ricky walked a total of 4 3/4
miles on the school track. He stopped every 1/4
mile to rest.
Rick stopped
times to rest. Round your answer to the nearest whole number, if necessary.
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
Fraction based problem: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

Complete the polynomial operation
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]

At an amusement park, 25 riders ride the race cars every 30 minutes and 20 riders ride the spinning swings every 20 minutes. Which ride will have more riders each hour and how many more? Use the drop-down menus to answer the problem. The Choose... will have Choose... more riders each hour.
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.
