Answers

Answer:

For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.

Step-by-step explanation:

College Board

Using the Central Limit Theorem, it is found that the correct option is:

C For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.

By the Central Limit Theorem, for a proportion p in a sample of size n, the mean of the sampling distribution of sample proportions is [tex]\mu = p[/tex], while the standard error is [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex

In this problem, the mean of the sampling distribution of sample proportions is 0.05, that is, the mean proportion of all samples, hence, the correct option is C.

Answers

Answer:

[tex]\angle BDA = 72^{\circ}[/tex]

[tex]\angle DAB = 36^{\circ}[/tex]

[tex]\angle BDC = 108^{\circ}[/tex]

[tex]\angle BCD = 36^{\circ}[/tex]

[tex]\angle DBC = 36^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle ABD = 72^{\circ}[/tex]

Required

Determine the missing angles

Since AB = AD, then:

[tex]\angle ABD = \angle BDA[/tex] --- Base angles of an isosceles triangle

Hence:

[tex]\angle ABD = \angle BDA = 72^{\circ}[/tex]

[tex]\angle ABD + \angle BDA + \angle DAB = 180^{\circ}[/tex] --- angles in a triangle

[tex]72^{\circ} + 72^{\circ} + \angle DAB = 180^{\circ}[/tex]

[tex]144^{\circ} + \angle DAB = 180^{\circ}[/tex]

Collect Like Terms

[tex]\angle DAB = 180^{\circ} - 144^{\circ}[/tex]

[tex]\angle DAB = 36^{\circ}[/tex]

[tex]\angle BDA + \angle BDC = 180^{\circ}[/tex] --- angle on a straight line

[tex]72^{\circ} + \angle BDC = 180^{\circ}[/tex]

[tex]\angle BDC = 180^{\circ} - 72^{\circ}[/tex]

[tex]\angle BDC = 108^{\circ}[/tex]

Since ABC is isosceles, then:

[tex]\angle DAB = \angle BCD = 36^{\circ}[/tex] --- base angle of isosceles

[tex]\angle BCD = 36^{\circ}[/tex]

Lastly:

[tex]\angle BCD + \angle BDC + \angle DBC = 180^{\circ}[/tex]

[tex]36^{\circ} + 108^{\circ} + \angle DBC = 180^{\circ}[/tex]

[tex]\angle DBC = 180^{\circ} - 36^{\circ} - 108^{\circ}[/tex]

[tex]\angle DBC = 36^{\circ}[/tex]

what single decimal multiplier would you use to increase by 14% followed by a 1% decrease?

Answers

Answer:

1.1286

Step-by-step explanation:

Increasing something by 14% is the same as taking 114% of it, and decreasing it by 1% is the same as taking 99% of it. 114% is 1.14 as a decimal, and 99% is 0.99 as a decimal, so multiplying the two together, we get the single decimal

1.14 · 0.99 = 1.1286

12.86% or a multiplier of 1.1286.

Assume the number 100.

100(1.14)=114
114(0.99)=112.86

What is the value of x in the solution to the this system of equations:
y=-1/2x + 2
y - 2x = -3

Answers

Answer:

x=2 and y=1

Step-by-step explanation:

hope this helps!

Answer:

x = 2

Step-by-step explanation:

For system of equations, you need to equal them to each other. First, you need to isolate y on one side of the equation in [tex]y - 2x = -3[/tex]

[tex]y = -3 + 2x[/tex]

Now, equal the equations to each other:

[tex]-\frac{1}{2}x + 2 = -3 + 2x[/tex]

Add [tex]\frac{1}{2} x[/tex] to both sides of the equation:

[tex]2 = -3 + (2x + \frac{1}{2}x) = -3 + (\frac{4}{2}x + \frac{1}{2}x) = -3 + \frac{5}{2} x[/tex]

Subtract add 3 to both sides of the equation:

[tex]5 = \frac{5}{2}x[/tex]

Divide [tex]\frac{5}{2}[/tex] on both sides of the equation. Remember: when you divide a fraction, you multiply by the reciprocal. See below:

[tex]\frac{2}{5} * 5 = x[/tex]

[tex]\frac{10}{5} = x[/tex]

[tex]x = 2[/tex]

Check your work:

[tex]-\frac{1}{2}(2) + 2 = -3 + 2(2)[/tex]

-1 = -1

Answer:

the value of the given equation is 8

Step-by-step explanation:

The computation is shown below

Given that

13 - 0.75w + 8x

here w = 12

x = 1 ÷ 2

Now put these values to the above equation

= 13 - 0.75 × (12) + 8 × (1 ÷ 2)

= 8

Hence, the value of the given equation is 8

Dogs Make Life GreatLet's face it, they don't call dogs "man's best friend" for nothing. They are sweet, they love us, and they do work for us. There is simply nothing better than a dog. If humans have learned to survive against saber-toothed predators, stampeding herds, and enduring famine, dogs have been right there. As Robin to our Batman, as Scooby Doo to our Shaggy, dogs have been there through thick and thin in our darkest hours. After all we've been through together, how could anyone disagree that dogs are the best pet any human could have?First, we get massive health benefits from dogs. They calm us down when we are stressed. Countless service dogs are trained every year to go into nursing homes and other facilities to provide comfort to patients. These therapy dogs have been shown to lower blood pressure and calm distressed patients. Dogs also bring sweet, sweet bacteria into our homes. These bacteria help build our immune systems and make us healthier. Studies have shown that people with dogs get sick less often. In addition, growing up with a dog in your home may make you less prone to dog-related allergies as you grow up. Finally, because dogs need regular exercise, dog owners tend to be more fit than those who do not own dogs or own only cats.Second, dogs just make us happier. New studies have found a lower rate of depression in dog owners. In part because dogs force their owners to be more active, it is likely that dog-owners just cannot stay cooped up at home all the time. This activity level also makes it easier to meet people, stay socially engaged, and feel a sense of belonging. They are dependable friends as well, always ready with a sympathetic ear, a soft belly to rub, and a willing smile. If your day seems like a version of the zombie apocalypse, ten minutes of playing fetch will certainly keep those zombies at bay until you can get back in the game.Finally, it's all about cute. Sure other pets can be cute, but consider tail wagging. What other animal has such a universally understood expression of joy? How can you not give into that sweet face, holding a stick, waiting patiently to be taken out to play? And if you have any doubts, you must not have seen a dog rolling on its back, tongue lolling about, head swishing back and forth, scooting first one way and then the next as if competing in a silly worm dance.Many cat owners may argue with this position, but dogs really are the best companions. They bring joy, like a bluebird brings spring, or a rainbow brings a promise. They teach us about patience. They teach us about faith, waiting patientlyno matter how many times we leave without themfor that one time they get to load into the car and go with us. Always ready to go, always ready to wait longer, they make us hurry home at the end of the day for just a little unconditional love.Read this sentence from the essay:They teach us about faith, waiting patientlyno matter how many times we leave without them-for that one time they get to load into the car and go with us.What is the main idea of this sentence?
