According to the given question, we have to find what proportion of overweight children have left atrial diameters greater than the mean for healthy children. To calculate the answer, we need to use the z-score of the left atrial diameter. We have to find the z-score value corresponding to the mean of healthy children and the standard deviation of the left atrial diameter of healthy children. Then, we will have to use the z-score formula.

Let’s solve it.Step-by-step explanation:Given that we need to calculate the proportion of overweight children with left atrial diameters greater than the mean of healthy children. Here, we can use the standard normal distribution to solve this problem. To solve this problem, we need to calculate the z-score for the mean of healthy children and the left atrial diameter of healthy children.1. Find the z-score for the mean of healthy children.z = (x - μ) / σz = (0 - 0) / 1z = 0 Thus, the z-score for the mean of healthy children is 0.2.

If a delivery truck is transporting boxes of two sizes: large and small. there are 70 large boxes and 65 small boxes in the truck.

Let's assume that x represents the number of large boxes, and y represents the number of small boxes.

We know that there are 135 boxes in total, so:

x + y = 135

We also know that the total weight of the boxes is 5475 pounds, so:

55x + 25y = 5475

Now we have a system of linear equations with two variables. We can use substitution or elimination to solve for x and y. Let's use substitution:

From the first equation, we can solve for x in terms of y:

x = 135 - y

Substitute this expression for x into the second equation:

55x + 25y = 5475

55(135 - y) + 25y = 5475

Simplify and solve for y:

7425 - 55y + 25y = 5475

30y = 1950

y = 65

Now we can use the first equation to solve for x:

x + y = 135

x + 65 = 135

x = 70

Therefore, there are 70 large boxes and 65 small boxes in the truck.

The slope of the line AB is 1.5 and the ratio of the sides is 2

The slope, m of line AB is solved using the formula

m = y2 - y1  / x2 - x1

using points 'A (-9, -5) and B (3, 3)

m = -9 - 3 / -5 - 3

m = -12 / -8

m = 1.5

For a similar triangle the ratio of side lengths are equal

AB / BC = AE / BD = BE / CD

The length of AB and BC is solved as follows

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points we want to find the distance between.

For AB:

x1 = -9, y1 = -5 (coordinates of A)

x2 = 3, y2 = 3 (coordinates of B)

distance_AB = sqrt((3 - (-9))^2 + (3 - (-5))^2)

distance_AB = sqrt(144 + 64)

distance_AB = sqrt(208)

distance_AB ≈ 14.42

For BC:

x1 = 3, y1 = 3 (coordinates of B)

x2 = 9, y2 = 7 (coordinates of C)

distance_BC = sqrt((9 - 3)^2 + (7 - 3)^2)

distance_BC = sqrt(36 + 16)

distance_BC = sqrt(52)

distance_BC ≈ 7.21

From the graph,

AE = 12

BD = 6

BE = 8

CD = 4

AB / BC = 14.42 / 7.21 = 2

AE / BD = 12 / 6 = 2

The 8th term of the given geometric sequence is -156250.

A sequence of numbers is called a geometric sequence if each term, except for the first term, is obtained by multiplying the previous term by a constant factor, which is called the common ratio.

The given sequence is a geometric sequence where each term is obtained by multiplying the previous term by -5.

So, the common ratio (r) between any two consecutive terms is -5.

To find the 8th term, we can use the formula for the nth term of a geometric sequence:

[tex]an = a1 * r^{(n-1)[/tex]

where,

an = 8th term

a1 = first term = 2

r = common ratio = -5

n = 8 (since we want to find the 8th term)

Therefore, substituting the values in the formula, we get:

[tex]a8 = 2 * (-5)^{(8-1)}\\\\a8 = 2 * (-5)^7\\\\a8 = 2 * (-78125)\\\\a8 = -156250[/tex]

The function has a local maximum at x = 1/3 and a local minimum at x = -4/3.

A quadratic equation is a second-order polynomial equation in a single variable x

ax²+bx+c=0

with a ≠ 0 . Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots x can be found by completing the square,

To analyze the function F(x) = -2x² - 6x³ + 4x + 1, we can begin by finding its derivative:

F'(x) = -4x - 18x² + 4

Then, we can find the critical points of the function by setting F'(x) equal to zero and solving for x:

-4x - 18x² + 4 = 0

Using the quadratic formula, we get:

x = (-(-4) ± ((-4)² - 4(-18)(4))) / (2(-18))

Simplifying, we get:

x = (-(-4) ± (400)²) / (-36)

x = (-(-4) ± 20) / (-36)

x = 1/3 or x = -4/3

So the critical points of the function are x = 1/3 and x = -4/3.

To determine the nature of these critical points, we can use the second derivative test.

F''(x) = -4 - 36x

Plugging in x = 1/3, we get:

F''(1/3) = -4 - 36(1/3) = -16 < 0

So x = 1/3 is a local maximum.

Plugging in x = -4/3, we get:

F''(-4/3) = -4 - 36(-4/3) = 40 > 0

So x = -4/3 is a local minimum.

Therefore, the function has a local maximum at x = 1/3 and a local minimum at x = -4/3.

Percent is a unit of measurement that represents a fraction of 100. It is often used to express a proportion or rate in relation to a total of 100. For example, if a sales tax is 7%, that means that for every $100 spent, $7 goes towards the tax. The symbol used to represent percent is %.

Here,

The formula for the value of the investment after t years is:

[tex]A = P(1+r/n)^{nt}[/tex]

where:

A is the amount of money after t years

P is the principal investment (initial amount invested)

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the time in years

Using this formula, we can plug in the values given in the problem:

P = 2000

r = 0.04

n = 12 (monthly compounding)

t = 3.5

A = [tex]2000(1 + 0.04/12)^{12*3.5}[/tex]

Lines AB and CD are parallel. If 6 measures (4x - 31)°, and 5 measures 111°, the value of x will be 21 if both angles are supplementary.

If lines AB and CD are parallel, then we can assume that m<5 and m<6 are supplementary that is the sum of both angles is 180 degrees

Therefore we can say that;

then 3x - 31 + 148 = 180

then 3x + 117 = 180

we need to then subtract 117 from both sides

therefore, 3x+117-117 = 180 - 117

then 3x = 180 - 117

The historical rate of defective widgets produced by ACME Corporation was 7%. Approximately, 91.2 is the standard deviations is the point estimate from 7%.

In statistics, standard deviation is a measure of the amount of variation or distribution of a set of values. A low standard deviation indicates that the values ​​tend to be close to the ensemble mean (also called the expected value), while a high standard deviation indicates that the values ​​are spread over a wider range.

The standard deviation can be abbreviated SD, and is most commonly used in mathematical texts and equations with the lowercase Greek letter σ (sigma) for the population standard deviation, or the Latin letter s for the standard deviation of the sample.

The standard deviation of a random variable, sample, population, data set, or probability distribution is the square root of its variance. It is algebraically simpler than the mean absolute deviation, although less robust in practice. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same units as the data.

The measure of the unknown angle is 93°

First we should get the interior angles of the triangle in the right side.

The angle in the left side is given by:

x  + 127° = 180°

x = 180° - 127°

x = 53°

While the angle in the right side is:

y + 146° = 180°

y = 180° - 146°

y = 34°

Now remember that the sum of the interior angles of a triangle must be 180°, then if the angle at the top is z we can write:

z + 34° + 53° = 180°

z = 180° - 34° - 53°
