Answers
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]

Rick stopped
times to rest. Round your answer to the nearest whole number, if necessary.
Answers
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

Suppose there is a 1.9°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 54.7°F, what will be the temperature when the plane reaches an altitude of 4,000 ft?
Answers
4000/1000 = 4
There are 4 drops in temperature.
1.9 x 4 = 7.6 total temperature drop.
54.7 - 7.6 = 47.1 F temperature
1.9 x 4 = 7.6 total temperature drop.
54.7 - 7.6 = 47.1 F temperature

Well, you can do this by first putting the numbers into point-slope form. That will be y-21=-4(x-0)
Then, you can simplify by doing the distributive property.
Lastly, add 21 on both sides to get the slope-intercept form.
y-21=-4x+0
+21 +21
y=-4x+21

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?
Answers
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]
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...
Answers
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.
