Answer 1

Answer:

x=12.727822

Step-by-step explanation:

Since we know two of the angles, we can find the third.  180-90-45=45.  This means the two sides of the triangle are also equal, and we know the hypotenuse is 18.  So we can use the Pythagorean theorem.

x²+x²=18²

2x²=324

x²=162

x=√162

x=12.727822

Answer:

Step-by-step explanation:

PEMDAS is going to be your best friend bud. It stands for Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction. This is the order you will use for all problems like this in the future. Start by solving everything inside the parenthesis.

6+3(11)-5^2=?

Now that all the parenthesis are gone we move on to exponents.

6+3(11)-(5*5)=?

6+3(11)-25=?

Now that all exponents are gone we solve for multiplication and division, whichever comes first when reading from left to right.

6+33-25=?

The final step is to add and subtract from left to right.

$90,314


$91,398


$103,999


$77,886

Answers

Answer:

$77,886

Step-by-step explanation:

We solve this question by proportions, using a rule of three.

The table states that:

$201.6 in 2006 is worth $232.957 in 2013.

We want to find:

The value of $90,000 in 2013 in 2006:

$201.6 - $232.957

x - $90000

Applying cross multiplication

[tex]232957x = 201.6*90000[/tex]

[tex]x = \frac{201.6*90000}{232957}[/tex]

[tex]x = 77886[/tex]

$77,886 is the answer

Step-by-step explanation:

[tex]\frac{1}{5}[/tex]

[tex]\frac{2}{10}[/tex]

[tex]\frac{20}{100}[/tex]

[tex]\frac{1}{5}[/tex] 1 × 2 = 2. 5 × 2 = 10. That is what makes [tex]\frac{2}{10}[/tex].

[tex]\frac{2}{10}[/tex] 2 × 10 = 20. 10 × 10 = 100. That is what makes [tex]\frac{20}{100}[/tex].

The probability of a head is 0.27. The coin is thrown 200 times. Write an

estimate for the amount of tails

Answers

Answer:

The estimate for the amount of tails is 146.

Step-by-step explanation:

For each throw, there are only two possible outcomes. Either it is a head, or it is tails. Throws are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

The probability of a head is 0.27.

This means that the probability of tails is [tex]p = 1 - 0.27 = 0.73[/tex]

The coin is thrown 200 times.

This means that [tex]n = 200[/tex]

Write an estimate for the amount of tails

This is the expected value, so:

[tex]E(X) = np = 200*0.73 = 146[/tex]

The estimate for the amount of tails is 146.

During a test period, an experimental group of 10 vehicles using an 85 percent ethanol-gasoline mixture showed mean CO2 emissions of 240 pounds per 100 miles, with a standard deviation of 20 pounds. A control group of 14 vehicles using regular gasoline showed mean CO2 emissions of 252 pounds per 100 miles with a standard deviation of 15 pounds. A quick comparison of the sample variances suggests that the population variances are:

a. probably equal.
b. probably unequal.
c. incomparable.

Answers

Answer:

Probably unequal  ( B )

Step-by-step explanation:

experimental group = 10

using 85% ethanol gasoline

mean = 240 pounds per 100 miles

standard deviation = 20 pounds

control group = 14 vehicles

using regular gasoline

mean = 252 pounds per 100 miles

standard deviation = 15 pounds

comparing  the sample variance of each group shows that they are probably unequal using the equation below

Variance for a sample set of data = ∑ ( x - X ) ^2 / n - 1

where n = number of events

X = mean value

x = value of events

What are absolute value functions?

An absolute value function is a function that contains an algebraic expression within absolute value symbols.

What is inequality?

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

According to the given question.

We have an inequality |3x| > x + 20

Solve the above given inequality |3x| > x + 20

⇒ [tex]-(x + 20) < 3x < +( x + 20)[/tex]

⇒ [tex]-x -20 < 3x < x + 20[/tex]

⇒ [tex]3x > -x -20[/tex] or [tex]3x < x + 20[/tex]

⇒ [tex]3x+x > -20[/tex] or [tex]3x - x < 20[/tex]

⇒ [tex]4x > -20[/tex] or [tex]2x < 20[/tex]

⇒[tex]x > -5[/tex] or [tex]x < 10[/tex]

⇒ x ∈ (-∞, -5)∪(10,∞)
