Answer 2

Answer:

[tex]x = \sqrt{12} = 3.464[/tex]

Step-by-step explanation:

[tex]AC=AD+DC=13\\\text{Because ABC is a right triangle then}\\AB^2=AD.AC\\\Rightarrow AB^2=1 \times 13=13\\\Rightarrow AB = \sqrt{13}\\\text{In the right triangle ABD, since Pythagoras we also have}\\AB^2=AD^2+BD^2\\\Rightarrow BD^2=AB^2-AD^2\\\Rightarrow x^2= 13 - 1=12\\\Rightarrow x = \sqrt{12} = 3.464.[/tex]

Step-by-step explanation:

one thing i could say it would not be C because if it were symetric, i already see 2 lines that are not symetrical in anyway

sure the graph could extend to infinity and negative infinity and if you see the right arrow, it is pointing down-wards, so if it goes bellow 0, point (0,0) would not be your expected number to see as the minimum

and between -1 and 1, yes, we can already see that the line from -1 and 1 is exponentially increasing

A past study claims that adults in America spend an average of 17 hours a week on leisure activities. A researcher wanted to test this claim. She took a sample of 10 adults and asked them about the time they spent per week on leisure activities. Their responses (in hours) are as follows:13242137152518224032Assume that the times spent on leisure activities by all adults are normally distributed. At the 5% significance level, can you conclude that the claim of this earlier study is true

Answers

Answer:

The claim is false.

Step-by-step explanation:

Given the data :

13 24 21 37 15 25 18 22 40 32

The sample mean and standard deviation can ben calculated for the given sample.

Using calculator :

Sample mean, xbar = 24.7

Sample standard deviation, s = 9.04

Sample size, n = 10

The hypothesis :

H0 : μ = 17

H1 : μ ≠ 17

The test statistic :

(xbar - μ) ÷ (s/√(n))

(24.7 - 17) ÷ (9.04/√(10))

7.7 / 2.8586990

Test statistic = 2.694

We can obtain the Pvalue, at α = 0.05 ; df = n-1 = 9

Pvalue = 0.0246

Since Pvalue < α ; we reject the null ; Hence, there is significant evidence to conclude that an adult American does not spend average of 17 hours in leisure

Answer: The sum of the interior angles of this shape is 720°.


Explanation: The formula to find the sum of the interior angles of any shape is: 180°(number of sides-2). The shape in this question has 6 sides, so when you substitute that into the formula, you get:

180°(6-2)
=720°

Therefore, the sum of the interior angles of this shape is 720°.


Hope that helps シ

Answer:

720 degrees

Step-by-step explanation:

sum of interior angles of any polygon is given by the equation

[tex]sum \: = (n - 2) \times 180[/tex]

where n is the number of sides of the polygon. in the question the polygon has 6 sides. hence n = 6 and

[tex]sum \: = (6 - 2) \times 180 \\ = 4 \times 180 \\ = 720 \: degrees[/tex]

12.) The FAA has to periodically revise their rules regarding weight estimates that vary by
season. Airlines currently use an estimate for the weight of an adult male passenger of 190 lbs.
in the summer that assumes
he carries sixteen pounds of baggage and has five pounds of
clothing. According to your textbook, assume that men (not clothed nor carrying baggage) have
weights that are normally distributed with a mean of 188.6 lbs. and a standard deviation of 38.9
lbs.

a.) If one adult male is randomly selected and is assumed to be also carrying 21 lbs. due to
clothing and baggage, find the probability that the total weight is greater than 190 lbs.

b.) What total weight would separate the lower 20% of men carrying 21 lbs. of clothing and
baggage from the top 80%?

Answers

Answer:

a) 0.4856 = 48.56% probability that the total weight is greater than 190 lbs.

b) A total weight of 155.9 lbs.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 188.6 lbs. and a standard deviation of 38.9 lbs.

This means that [tex]\mu = 188.6, \sigma = 38.9[/etx]

21 lbs of baggage are taken into consideration in this estimate.

a.) If one adult male is randomly selected and is assumed to be also carrying 21 lbs. due to clothing and baggage, find the probability that the total weight is greater than 190 lbs.

This is 1 subtracted by the the p-value of Z = 190. So

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

[tex]Z = \frac{190 - 188.6}{38.9}[/tex]

[tex]Z = 0.036[/tex]

[tex]Z = 0.036[/tex] has a p-value of 0.5144.

1 - 0.5144 = 0.4856.

0.4856 = 48.56% probability that the total weight is greater than 190 lbs.

b.) What total weight would separate the lower 20% of men carrying 21 lbs. of clothing and baggage from the top 80%?

This is the 20th percentile, which is X when Z has a p-value of 0.2, so X when Z = -0.84.

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

[tex]-0.84 = \frac{X - 188.6}{38.9}[/tex]

[tex]X - 188.6 = -0.84*38.9[/tex]

[tex]X = 155.9[/tex]

A total weight of 155.9 lbs.

Step-by-step explanation:

To find the number midway between 3/2 and 4/2, add them up and divide by 2

we have, 3/2 + 4/2 = 7/2

7/2 ÷ 2 = 7/4

Repeat the same for the number midway between 1/2 and 2/2 to get 3/4

The answer then is, 7/4 - 3/4 = 4/4

write the equation of a circle with a center at (-1, -4) that passes through the point (-1,-1)

Answers

Answer:

Equation of the circle :  

                      [tex](x+ 1)^2 + (y+4)^2 = 9[/tex]

Step-by-step explanation:

Equation of a circle with centre (a, b) and radius ,r :

[tex](x - a)^2 + (y-b)^2 = r^2[/tex] ------(1)

Here a = -1, b = -4

find radius:

Since the circle passes through (-1, -1) , the radius is the distance between the centre and the point.

[tex]distance, r = \sqrt{(-1 -(-1))^2 +(-4 -(-1))^2 }[/tex]

               [tex]= \sqrt{9} = 3[/tex]

Substitute the values in (1) :

             [tex](x - (-1))^2 + (y-(-4))^2 = 3^2\\\\(x+ 1)^2 + (y+4)^2 = 9[/tex]

C. More students are between 54 and 60 inches than between 46 and 50 inches in height.

Fewer students are between 44 and 52 inches than between 52 and 60 inches in height.

D

Answers

Answer:

Fewer students are between 44 and 52 inches than between 52 and 60 inches in height.

Step-by-step explanation:

Given

See attachment for histogram

Required

Select the true statement

Option A: Class 46-50 = 12 students

From the histogram, we have:'

[tex]Class\ 46 - 48 = 8; Class\ 48 - 50 = 3[/tex]

So:

[tex]Class\ 46 - 48 = Class\ 46 - 48 + Class\ 48 - 50[/tex]

[tex]Class\ 46 - 48 = 8+ 3[/tex]

[tex]Class\ 46 - 48 = 11[/tex]

(a) is false

Option B: %Class 52-54 = 18%

From the histogram, we have:'

[tex]Class\ 52-54 = 18[/tex]

and

[tex]Total = 53[/tex]

So, the percentage is:

[tex]\% Class\ 52-54 = \frac{Class\ 52-54}{Total}[/tex]

[tex]\% Class\ 52-54 = \frac{18}{53}[/tex]

[tex]\% Class\ 52-54 = 0.3396[/tex]

Express as percentage:

[tex]\% Class\ 52-54 = 33.96\%[/tex]

(b) is false

Option C: Class 54-60 > Class 46 - 50 students

From the histogram, we have:'

[tex]Class\ 54-60 =Class\ 54-56 + Class\ 56-58 + Class\ 58-60[/tex]

[tex]Class\ 54-60 = 4 + 4+3[/tex]

[tex]Class\ 54-60 = 11[/tex]

In (a), we have:

[tex]Class\ 46 - 48 = 11[/tex]

By comparison:

[tex]Class\ 54-60 =Class\ 46 - 48 = 11[/tex]

(c) is false

Option D: Class 44-52 < Class 52 - 60 students

From the histogram, we have:'

[tex]Class\ 44-52 =Class\ 44-56 + Class\ 46-48 + Class\ 48-50 +Class\ 50-52[/tex]

[tex]Class\ 44-52 = 4+8+3+9[/tex]

[tex]Class\ 44-52 = 24[/tex]

[tex]Class\ 52-60 =Class\ 52 - 54 + Class\ 54-56 + Class\ 56-58 + Class\ 58-60[/tex]

[tex]Class\ 52-60 = 18+ 4 + 4+3[/tex]

[tex]Class\ 52-60 = 29[/tex]

By comparison:

[tex]24 < 29[/tex]

i.e.

[tex]Class\ 44 - 55 < Class\ 52 - 60[/tex]

(d) is true
