Are Tan D And Tan F ____.a. Complementary B. Supplementary C. Congruentd. Reciprocals

Answers

Answer 1
Answer:  Reciprocals

Reason:

tan = opposite/adjacent

tan(D) = EF/DE = d/f

tan(F) = DE/EF = f/d

Comparing d/f with f/d, and we find they are reciprocals. The two fractions multiply to 1.

Which do the following options represent the measure of arc RA

A.38.6
B.65.6
C.71.4
D.77.2

Answers

Answer:

77.2°

Step-by-step explanation:

Consider the triangle JKR.

∠KJR=108.6 (lies on the same line as ∠RJA, angles on a straight line add up to 180)

All the angles in a triangle add up to 180, so:

∠JKR+∠KJR+∠JRK=180

∠JKR+108.6+32.8=180

∠JKR=38.6=∠RKA

Consider ∠RKA. This angle stands on the same arc as ∠RCA.

Since the angle at centre is twice the angle at circumference, 2(∠RKA) = ∠RCA.

2(∠RKA) = ∠RCA

2(38.6)=∠RCA

∠RCA=77.2°

Write an equation using “x” and then solve the equation. The rate charged for a standard room is $250 dollars. A couple stayed in a standard room for x nights and their total room charge is $750.

Answers

Answer:

3 nights

Step-by-step explanation:

total charge = rate times time interval

Here, time interval = total charge / rate

                               $750 = ($250/night)(n nights)

                                Solving for n, we get n = 3 (nights)

An equation for a couple stayed in a standard room for x nights and their total room charge is $750 is, 250x  = 750

What is an Equation ?

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Given that,

The distance from New York City to Riverhead is approximately 150 miles. On a map whose scale is 24mi= 2inch, what is the distance between the two locations in inches?​

Answers

Answer:

12.5 inches

Step-by-step explanation:

Given

[tex]Distance = 150\ miles[/tex]

[tex]Scale:= 24\ miles : 2\ inches[/tex]

Required

Determine the measurement in inches

Represent the inches equivalent with d.

So, the scale can also be calculated as:

[tex]Scale:= 150\ miles: d[/tex]

Equate both scales

[tex]150\ miles: d = 24\ miles ; 2\ inches[/tex]

Convert to fraction

[tex]\frac{d}{150\ miles} = \frac{2\ inches}{24\ miles}[/tex]

[tex]\frac{d}{150} = \frac{2\ inches}{24}[/tex]

Multiply both sides by 150

[tex]150 * \frac{d}{150} = \frac{2\ inches}{24} * 150[/tex]

[tex]d = \frac{2\ inches}{24} * 150[/tex]

[tex]d = \frac{2\ inches * 150}{24}[/tex]

[tex]d = \frac{300\ inches}{24}[/tex]

[tex]d =12.5\ inches[/tex]

Multiplying by 2/2 is like multiplying by 1, so it doesn't affect the value.

To add fractions with the same denominator just add the numerator, the denominator stays the same.

The fraction is 2/8 and the sum is 5/8.

What is Fraction?

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.

Given:

let the numerator be x when denominator is 8.

so, 1/4 = x /8

8 = 4x

x= 8/4

x= 2

Now, fraction resulted above is added with 3/8

2/8 + 3/8

= (2+3)/8

= 5/8

Hence, the sum is 5/8.

Determine if the finite correction factor should be used. If​ so, use it in your calculations when you find the probability. In a sample of 800 gas​ stations, the mean price for regular gasoline at the pump was $2.816 per gallon and the standard deviation was ​$0.008 per gallon. A random sample of size 45 is drawn from this population. What is the probability that the mean price per gallon is less than ​$2.812​?

Answers

Answer:

0.0003 = 0.03% probability that the mean price per gallon is less than ​$2.812​

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Finite correction factor:

If the sample is more than 5% of the population, instead of Central Limit Theorem, we use the finite correction factor, as the standard deviation of the sampling distribution would be too big.

The mean price for regular gasoline at the pump was $2.816 per gallon and the standard deviation was ​$0.008 per gallon.

Large sample, so this can be treated as the population data. Then [tex]\mu = 2.816, \sigma = 0.008[/tex]

Sample of 45:

45/800 = 0.056 = 5.6% -> Sample more than 5% of the population, so we use the finite correction factor. This means that s will be multiplied by:

[tex]FCF = \sqrt{\frac{N-n}{N-1}}[/tex]

In which n is the size of the sample(45) and N is the size of the population (800). So

[tex]FCF = \sqrt{\frac{755}{799}} = 0.9721[/tex]

By the Central Limit Theorem, [tex]n = 45, s = 0.9721*\frac{0.008}{\sqrt{45}} = 0.00116[/tex]

What is the probability that the mean price per gallon is less than ​$2.812​?

This is the pvalue of Z when X = 2.812. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{2.812 - 2.816}{0.00116}[/tex]

[tex]Z = -3.45[/tex]

[tex]Z = -3.45[/tex] has a pvalue of 0.0003

0.0003 = 0.03% probability that the mean price per gallon is less than ​$2.812​

The smallest angle of a triangle is measure x degrees. The second angle is 45 degrees more than the smallest angle. The third angle is three times larger as the smallest angle. Write algebraic expression to express measures of the second and third angles of the triangle.

Answers

Answer:

Smallest angle = 27°

Second angle = 72°

Third angle = 81°

Step-by-step explanation:

Given:

In triangle

Smallest angle = x

Second angle = x + 45

Third angle = 3x

Find:

All angle

Computation:

Using angle sum property

x + x + 45 + 3x = 180

5x + 45 = 180

x = 27

Smallest angle = 27°

Second angle = x + 45

Second angle = 27 + 45

Second angle = 72°

Third angle = 3x

Third angle = 3(27)

Third angle = 81°

The data set which could not be represented by the box plot is

{6, 4, 7, 9, 8, 8, 12, 10, 12, 13, 13}​

Option D is the correct answer.

What is a median?

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

From the box plot,

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

Now,

Arrange the number in order.

A)

{12, 5, 10, 7, 8, 14, 7, 10, 4, 13, 9}

= {4, 5, 7, 7, 8, 9, 10, 10, 12, 13, 14}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

B)

{8, 12, 7, 8, 4, 9, 10, 12, 6, 14, 13)

= {4, 6, 7, 8, 8, 9, 10, 12, 12, 13, 14}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

C)

{14, 5, 13, 8, 8, 10, 9, 11, 12, 7, 4 }

= {4, 5, 7, 8, 8, 9, 10, 11, 12, 13, 14}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

D)

{6, 4, 7, 9, 8, 8, 12, 10, 12, 13, 13}​

= {4, 6, 7, 8, 8, 9, 10, 12, 12, 13, 13}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 13

Minimum = 4
