It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minutes per day that people spend standing or walking. Among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately Normally distributed with 376 minutes and standard deviation 70 minutes. The mean number of minutes of daily activity for lean people is approximately Normally distributed with 526 minutes and standard deviation 106 minutes. A researcher records the minutes of activity for an SRS of 6 mildly obese people and an SRS of 6 lean people.

Required:
a. What is the probability that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 410 minutes?
b. What is the probability that the mean number of minutes of daily activity of the 6 lean people exceeds 410 minutes?

Answers

Answer 1

Answer:

0.9963 is the probabilities that mean number of daily activity of 6 lean people exceed 410 minutes.

Step-by-step explanation:

Solution:

6 Mildly obese people exceed 410 minutes.

Given:

Mean = µ = 376

Standard deviation = ∂ = 70

n = 6

p (x> 410) = p (z > x - µ/ ∂ / √n)

                 = p (z > 410 – 376 / 70 /√6 )

                 = p (z > 1.185)

                 = 1 – p (z < 1.185)

                 = 1 – 0.38199

                = 0.618

0.618 is the probability that the mean number of minutes of daily activity of 6 mildly obese people exceed 410 minutes.

6 lean people exceed 410 minutes:

Given:

Mean = µ = 526

Standard deviation = ∂ = 106

n = 6

=p(x > 410)

= p (z > x - µ/ ∂ /√n)

=p (z > (410 – 526 ) / 106 / √ 6 )

= p (z > - 2.67)

= p (z <2.68)

= 0.9963

0.9963 is the probabilities that mean number of daily activity of 6 lean people exceed 410 minutes.

What is 3/7 of $56
I am not sure

Answers

Answer:

$24

Step-by-step explanation:

1. MULTIPLY: 3 x 56 = 168

2. DIVIDE: 168 / 7 = $24

I hope this helps!

Based on multiplication we have found that 3/7 of $56 is equal to $24.

We are given that the expression 3/7 of $56

To determine 3/7 of $56, we can multiply 3/7 by $56.

Multiply 3/7 by $56:

(3/7) x $56 = (3 x $56) / 7

Calculate the numerator:

3 x $56 = $168

Divide the numerator by the denominator:

$168 / 7 = $24

Therefore, 3/7 of $56 is equal to $24.

Answers

Answer:

The volume of a prism is given by ...

 V = Bh

Step-by-step explanation:

Here, the base is an equilateral triangle with side length 3 in. The area of such a triangle is given by

 A = (√3)4*s²

where s is the side length.

Your triangular prism has a base area of ...

 B = (√3)/4*(3 in)² = (9/4)√3 in²

so the volume is

 V = ((9/4)√3 in²)(6 in)

 V = (27/2)√3 in³

 V ≈ 23.383 in³

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Ok so since this is an area question we should begin with writing the correct formula for it. This says it's rectangular pool so we'll be using our rectangle formula, which is...

[tex]A=lw[/tex]

Now we plug in what we know...

[tex]length=30\frac{1}{3} \\width=12\frac{1}{2}[/tex]

Now we solve...

[tex]A=lw\\A=(30\frac{1}{3})(12\frac{1}{2})\\A=379\frac{1}{6}[/tex]

So the area is.... [tex]379\frac{1}{6}[/tex] feet ²

or if you want an improper fraction....[tex]\frac{2275}{6}[/tex] feet²

or a decimal... [tex]379.1666667=379.17[/tex] feet².

Answers

Given parameters:

Bearing of the tree from the house  = 295°

Unknown:

Bearing of the house from the tree = ?

Solution:

This is whole circle bearing problem(wcb). There are different ways of representing directions from one place to another. In whole circle bearing, the value of the bearing varies from 0° to 360° in the clockwise direction.

To find the back bearing in this regard, simple deduct the forward bearing from 360°;

    Backward bearing  = 360° -295°

                                    = 65°

The bearing from house to the tree is 65°

Answer:

x = 8

Step-by-step explanation:

Complementary angles are two angles with measures that sum to 90°

Given:

m∠C = (5x)° m∠D = (7x − 6)°

at the movies, la quinta paid for drinks and popcorn for herself and her two children. she spend twice as much on popcorn as on drinks. if her total bill came to $17.94, how much did she spend on drinks and how much did she spend on popcorn?

Answers

Answer:

Step-by-step explanation:

let the amount spent on popcorn be x and amount spent on drinks be y

If the total bill paid is  $17.94, then x+y =  $17.94

If she spend twice as much on popcorn as on drinks, then y = 2x

Substitute y = 2x into the original equation

x+y =  $17.94

x + 2x =  $17.94

3x =  $17.94

x =  $17.94/3

x = $5.98

Since y = 2x

y = 2($5.98)

y = $11.96

Therefore she spent  $5.98 on popcorn and $11.96 on drinks
