Answer: Width of 32 inches high school flag = 72 inches.

Height of 48 inches wide school flag = 21.3 inches

Step-by-step explanation:

Given : Washington Middle school's school flag has a height -width ratio of 12:27.                                         (1)

Let x be the width of 32 inches high school flag.

Then height -width ratio = \dfrac{32}{h}             (2)

From (1) and (2) , we have

\dfrac{32}{x}=\dfrac{12}{27}\\\\\Rightarrow\ x=\dfrac{27\times32}{12}=72    

Hence, width of 32 inches high school flag = 72 inches.

Let h be the height of 48 inches wide school flag.

Then height -width ratio = \dfrac{h}{48}             (3)

From (1) and (3) , we have

\dfrac{h}{48}=\dfrac{12}{27}\\\\\Rightarrow\ h=\dfrac{12\times48}{27}=21.3333333333\approx21.3    

Hence, height of 48 inches wide school flag = 21.3 inches

Answer:

Step-by-step explanation:

7x - 15 = 4x - 12

3x - 15 = -12

3x = 3

x = 1

y = 7(1) - 15

y = 7 - 15

y = -8

Polygons ABCD and EFGH are similar. What is the perimeter of EFGH?
Rom4ik [11]
If polygons ABCD and EFGH are similar, then their perimeters most likely are also similar. Polygon EFGH also have the same perimeter with polygon ABCD. Having similar polygons is referred as congruent polygons. <span>Two figures are said to be congruent when they have the same shape and size or if one object is a mirror image of the other object.<span> </span></span>

Given that a 90% confidence interval for the mean height of all adult males in Idaho measured in inches was [62.532, 76.478]. Us
grigory [225]

Answer:

The confidence interval on this case is given by:

\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}} (1)

For this case the confidence interval is given by (62.532, 76.478)[/tex]

And we can calculate the mean with this:

\bar X = \frac{62.532+76.478}{2}= 69.505

So then the mean for this case is 69.505

Step-by-step explanation:

Previous concepts

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

\bar X represent the sample mean  

\mu population mean (variable of interest)  

\sigma represent the population standard deviation  

n represent the sample size  

Assuming the X follows a normal distribution  

X \sim N(\mu, \sigma)

The confidence interval on this case is given by:

\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}} (1)

For this case the confidence interval is given by (62.532, 76.478)[/tex]

And we can calculate the mean with this:

\bar X = \frac{62.532+76.478}{2}= 69.505

So then the mean for this case is 69.505

The pH level of tomato juice is 4.2. What is the hydrogen-ion concentration [H+]| for tomato juice?
garri49 [273]

Given:

pH = 4.2 of tomato

Required:

hydrogen-ion concentration [H+]| for tomato juice

Solution:

The formula for the pH relating hydrogen ion concentration is pH = -log[H+] where H+ is the hydrogen ion concentration. so, substitute the value of pH

pH = -log[H+]

4 = - log[H+]

-4 = log[H+]

10^-4 = [H+]

[H+] = 1x10^-4M

Inessa [10]

Answer:

largest angle measures 108°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

8x - 6 + 108 + 14 = 180, simplify left side

8x + 116 = 180 ( subtract 116 from both sides )

8x = 64 ( divide both sides by 8 )

x = 8

Thus

∠ U = 8x - 6 = 8(8) - 6 = 64 - 6 = 58°

Then the largest angle measures 108° ( ∠ B )
