It was recently estimated that domestic vehicles outnumber foreign vehicles by about three to two. If there are 1925 vehicles in a county, how many of them are domestic?

Answers

If domestic vehicles outnumber foreign vehicles by about three to two and vehicles in a country are 1925 then Domestic vehicles would be {(1925)x(3/5)} = 1155

Assume that the growth of the membership of a country club was linear from 1996 to 2000 with a membership of 169 in 1996 and a rate growth of 674 per year

Answers

The equation for the number of members after [tex]x[/tex] years is [tex]P=674x+169[/tex].

The members after [tex]6[/tex] years are [tex]4213[/tex].

Let [tex]x[/tex] be the number of years after [tex]1996[/tex] and [tex]P[/tex] be the number of members.

The membership in [tex]1996[/tex] is [tex]169[/tex].

Rate growth of [tex]674[/tex] per year.

So, the equation for the number of members after [tex]x[/tex] years is [tex]P=674x+169[/tex].

For the members after [tex]6[/tex] years, put [tex]x=6[/tex] in the equation,

[tex]P=674 \times 6 + 169[/tex]

[tex]P=4044+169[/tex]

[tex]P=4213[/tex].

In the diagram below find the measure of each of the three angles and then state which two are complementary and which two are a supplementary pair. Answer question 1 and two.

Answers

1) ∠C and ∠G are supplementary while ∠A and ∠G are complementary.

2) Yes, ∠D is supplementary to ∠GAH

This is based on understanding complementary and supplementary angles.

By definition, complementary angles are two angles whose sum is equal to 90°. Meanwhile supplementary angles are those whose sum is equal to 180°.

1) From the angles drawn, we can see that ∠A and ∠G are less than 90° while ∠C is greater than 90° but less than 180°.

From inspection, ∠A looks same angle with ∠G. But, for them to be complementary they have to add up to 90°. Thus;

∠A + ∠G = 90°

Since ∠A = ∠G, then ∠A = ∠G = 90/2 = 45°

Now, ∠C appears to be the remaining part of ∠G to complete a straight line.

We know that sum of angles on a straight line is 180°

Thus;

∠C + ∠G = 180°

∠C + 45° = 180°

∠C = 180° - 45°

∠C = 135°

Thus, ∠C and ∠G are supplementary while ∠A and ∠G are complementary.

2) We see that ∠D = 63°

For ∠D to be supplementary to ∠GAH, it means that ∠GAH must be 180° - 63° = 117°

By inspection, it looks permissible.

Thus, ∠D is supplementary to ∠GAH

Step-by-step explanation:

Therefore, the first number in an ordered pair is a value for x, and the second number is a value for y. These numbers are called the x- and y-coordinates.Jan 6, 2020

Answer:

x = 42

y = 48

Step-by-step explanation:

Because opposite angles are equal:

2x - 11 = 73

Add 11 to each side:

2x - 11 + 11 = 73 + 11

Simplify

2x = 84

Divide both sides by 2:

x = 42

And because angle y is opposite to the 48° angle, it is equal.

So y = 48

Answers

Using concepts of complex numbers, it is found that the modulus of -2 -6i is of 6.3, given by option A.

--------------------------------

A complex number has the format a + bi, in which a represents the real part and b represents the imaginary part.The modulus of the number, also called absolute value, is given by [tex]|a + bi| = \sqrt{a^2 + b^2}[/tex].In this question, the number is -2 -6i, thus [tex]a = -2, b = -6[/tex], and the modulus is:

[tex]|-2 -6i| = \sqrt{(-2)^2 + 6^2} = \sqrt{4 + 36} = \sqrt{40} = 6.3[/tex]

The modulus of -2 -6i is of 6.3, given by option A.

Sales of statin on January 1, 2007 was _______billion dollars.
Statin sales reached 20 billion dollars in the year ________

Answers

Sales of statin on January 1, 2007 was 16.6 billion dollars.

Statin sales reached 20 billion dollars in the year 2009

Explanation :

The equation: S= 1.3x + 4.9 estimates the amount of sales, S, of statin (in billions of dollars) x years after January 1, 1998.

In 1998, the value of x=0

We need to find the sales in 2007.

2007 - 1998= 9 years

x=9 for the year 2007.

Substitute x=9 in the given equation S to find out sales

[tex]S= 1.3x + 4.9\\S= 1.3(9) + 4.9\\S=16.6[/tex]

Sales of statin on January 1, 2007 was 16.6 billion dollars.

Now we find out the year when sales reached 20 billion dollars

S is the amount of sales in billion dollars .

Substitute 20 for S and solve for x

[tex]S= 1.3x + 4.9\\20=1.3x+4.9\\20-4.9=1.3x\\\\15.1=1.3x\\Divide \; by \; 1.3\\x=11.61538[/tex]

So , 11 years.

To find out the year , we add 11 with 1998

1998+11=2009

Statin sales reached 20 billion dollars in the year 2009

How can I calculate standard deviation? ›

In this method, we first compute the mean of the data values (¯x x ¯ ) and then compute the deviations of each data value from the mean. Then we use the following standard deviation formula by actual mean method: σ = √(∑(x−¯x) ( x − x ¯ ) 2 /n), where n = total number of observations.

What is the standard deviation a measure of the _____________ of a set of data? ›

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low, or small, standard deviation indicates data are clustered tightly around the mean, and high, or large, standard deviation indicates data are more spread out.

What is the standard deviation when the variance is 144? ›

Then the standard deviation of the data is: A. ±12.

What is a bell-shaped distribution with a mean? ›

Key Takeaways. A bell curve is a graph depicting the normal distribution, which has a shape reminiscent of a bell. The top of the curve shows the mean, mode, and median of the data collected. Its standard deviation depicts the bell curve's relative width around the mean.

What is the bell-shaped distribution and standard deviation? ›

Standard deviation is a measure of dispersion or spread within a distribution. For a bell curve, the standard deviation can be considered as approximately measuring the width of the central bell. If the distribution is normal, about 68% of values will fall within a range of one deviation from the central mean value.

What is the mean and standard deviation of the bell curve? ›

The shape of a normal distribution is determined by the mean and the standard deviation. The steeper the bell curve, the smaller the standard deviation. If the examples are spread far apart, the bell curve will be much flatter, meaning the standard deviation is large.

What is the empirical rule if a distribution is bell-shaped? ›

In any normal or bell-shaped distribution, roughly... 68% of the observations lie within one standard deviation to either side of the mean. 95% of the observations lie within two standard deviations to either side of the mean.

When a distribution is bell-shaped, approximately what percentage of the data values will fall within 1 standard deviation of the mean? ›

The empirical rule says that if a distribution is roughly bell​ shaped, the following is true. ​· Approximately​ 68% of the data will lie within 1 standard deviation of the mean. ​· Approximately​ 95% of the data will lie within 2 standard deviations of the mean.

What is also known as the bell-shaped curve? ›

The Bell-shaped Curve is commonly called the normal curve and is mathematically referred to as the Gaussian probability distribution. Unlike Bernoulli trials which are based on discrete counts, the normal distribution is used to determine the probability of a continuous random variable.
