Answer:

a = 664.5

b = 502.3

c = 767.3

Step-by-step explanation:

Well, there are a couple of theorems that will help us do this problem

1.  Given a right triangle and altitude to the hypotenuse, then the altitude is the mean proportion between the segments of the hypotenuse.  That means in your problem that

\(\frac{435}{b} = \frac{b}{580}\)    

\(b^{2} = 435(580) = 252300\\b = \sqrt{252300} \\b = 502.3\)

2.  A leg of the triangle is the mean proportional between the hypotenuse and the segment adjacent to the leg.  That means in your problem that

\(\frac{(435 + 580)}{c} = \frac{c}{580} \\c^{2} = 1015(580) = 588700\\c = \sqrt{588700} \\c = 767.3\)

\(\frac{1015}{a} = \frac{a}{435} \\a^{2} = 1015(435) = 441525\\a = \sqrt{441525} \\a = 664.5\)

See how easy it is if you know the theorems.  

You could check your results by substituting a and  into \(a^{2} + c^{2}\) and see if you get get the square of the hypotenuse

Answer: 9 months.

Step-by-step explanation:

Simple interest = Principal x rate(in decimal)  x Time(in years)

Given: Principal = $15,000 , rate = \(5\dfrac12\%=\dfrac{11}{2}\%= 5.5\%= 0.055\)

Interest =  $618.75

let t= time

Then,

\(618.75=15000\times 0.055\times t\\\\\Rightarrow\ t=\dfrac{618.75}{15000\times0.055}\\\\\Rightarrow\ t= 0.75\ or\ t=\dfrac34\ year\)

1 year =12 months

\(\dfrac34\ year=\dfrac34\times12 = 9\ months\)

Hence, it will take 9 months.

According to the information, we can infer that the number of ounces of water, x, that Will could have put in each cup is 8 ounces.

Will initially had a cooler filled with 144 ounces of water. After using 16 ounces to fill his water bottle, there were 144 - 16 = 128 ounces of water remaining in the cooler.

Will then took out 16 plastic cups for his teammates. Since the same amount of water was put in each cup, the remaining amount of water, 128 ounces, needs to be divided equally among the cups.

Dividing 128 ounces by 16 cups gives us 8 ounces of water for each cup.

So, Will could have put 8 ounces of water in each cup.

Step-by-step explanation:

the slop of line l is 6

half of that is 3

have a wonderful day <3

Answer:

2. b : l

3. 20cm

4. 49 \(cm^{2}\)

5. \((2\pi+1):2\pi\)

Step-by-step explanation:

Solution 2:

Let cylinder is rolled along 'l':

Height of cylinder , h = length of rectangle = l

Perimeter of base = b

Let 'r' be the radius of cylinder's base:

\(2\pi r = b\\\Rightarrow r = \dfrac{b}{2\pi}\)

Volume of a cylinder is given as:

\(V = \pi r^{2} h\)

Putting the values:

\(V_1 = \pi (\dfrac{b}{2\pi})^2 l\\\Rightarrow V_1 = (\dfrac{b^2}{4\pi}) l\)

Let cylinder is rolled along 'b':

Height of cylinder , h = length of rectangle = b

Perimeter of base = l

Let 'r' be the radius of cylinder's base:

\(2\pi r = l\\\Rightarrow r = \dfrac{l}{2\pi}\)

Volume of a cylinder is given as:

\(V = \pi r^{2} h\)

Putting the values:

\(V_2 = \pi (\dfrac{l}{2\pi})^2 b\\\Rightarrow V_2 = (\dfrac{l^2}{4\pi}) b\)

Taking ratio:

\(V_1:V_2 = \dfrac{(\dfrac{b^2}{4\pi}) l}{(\dfrac{l^2}{4\pi}) b} = b:l\)

Solution 3:

Rectangle is rolled along its length to make a cylinder, so height will be equal to its length.

\(\therefore\) height of cylinder = 20 cm

Solution 4:

Side of square = 7 cm

Height of cylinder =Side of square = 7 cm

7 cm will be the circumference of the circle.

i.e. \(2\pi r\) = 7 cm

Curved surface area of a cylinder:

\(CSA = 2\pi rh\)

Putting the above values:

CSA = 7 \(\times\) 7 = 49 \(cm^{2}\)

Solution 5:

As calculated in above step:

CSA = \(2\pi rh =\) 7 \(\times\) 7 = 49 \(cm^{2}\)

Total surface area = \(2\pi r^{2} + 2\pi r h\)

Calculating value of r:

\(2\pi r\) = 7 cm

\(\Rightarrow 2 \pi r = 7\\\Rightarrow r = \dfrac{7}{2\pi}\)

Total surface area =

\(2\pi (\dfrac{7}{2\pi})^{2} + 49\\\Rightarrow \dfrac{49}{2\pi}+49\\\Rightarrow 49(\dfrac{1}{2\pi}+1) cm^2\)

Ratio of TSA: CSA is

\(49(\dfrac{1}{2\pi}+1) cm^2 : 49 cm^2\\\Rightarrow (\dfrac{1}{2\pi}+1):1\\\Rightarrow (2\pi+1): 2\pi\)

Answer:

Option 2: 1.5 is the correct answer.

Step-by-step explanation:

Given information is:

Mean = μ = $27

SD = σ = $5.50

A z-score simply tells us how far a selected data value from the mean is.

Z-score is denoted by z and is given by the formula:

\(z = \frac{x-mean}{SD}\)

Let x = $35.25

Putting the values of mean and SD we get,

\(z = \frac{35.25-27}{5.50}\\z = \frac{8.25}{5.50}\\z =1.5\)

The value of z-score for a price of $35.25 per barrel is 1.5

Hence,

Option 2: 1.5 is the correct answer.

Answer:

$1053

Step-by-step explanation:

If we have that £1 = $1.62, then we can multiply both sides by 650 in order to get £650 on the left side of the equality. We must multiply the right side also by 650, and so we get £650=$1.62 * 650.

To do this multiplication, we can break 1.62 down  simply into $1.00 +$0.6+$0.02

650*$1.00=$650, 650*$0.6=650*6/10=65*6=$390, and 650*$0.02=650*2/100=6.5*2=$13.

When we add these three products together, we get $650+$390+$13=$1053. And so, £650=$1053

the probability of a patient with a tumor diameter of 5.5 and tumor coarseness of 0.7 being a non-cancer patient is approximately 0.9106, or 91.06%.

To find the probability of a patient with a tumor diameter of 5.5 and tumor coarseness of 0.7 being a non-cancer patient using the logistic regression model with the given mathematical function, we need to apply the sigmoid function to the linear combination of the features.

The sigmoid function, also known as the logistic function, is defined as:

σ(z) = 1 / (1 + e^(-z))

where z is the linear combination of the features. In this case, the linear combination is given by:

z = 0.2 + 0.25 * tumor_diameter + 1.1 * tumor_coarseness

Substituting the values of tumor_diameter = 5.5 and tumor_coarseness = 0.7 into the equation, we get:

z = 0.2 + 0.25 * 5.5 + 1.1 * 0.7

z = 0.2 + 1.375 + 0.77

z = 2.345

Now, we can calculate the probability using the sigmoid function:

P(non-cancer) = σ(z) = 1 / (1 + e^(-2.345))

Calculating this value, we find that:

P(non-cancer) ≈ 0.9106

Therefore, the probability of a patient with a tumor diameter of 5.5 and tumor coarseness of 0.7 being a non-cancer patient is approximately 0.9106, or 91.06%.

Starting with the least likely event, the chances of a politician fulfilling all his or her campaign promises can be quite low due to the complexities of politics and the potential for unforeseen circumstances.

Next, while full moons are relatively common, they occur approximately once a month, making it more likely than the politician's scenario but less likely than the other events.

Rolling a die and getting a 6 has a higher likelihood as there is a 1 in 6 chance of rolling a 6 on a fair six-sided die. The safe arrival of a person in New York City from Chicago is more probable than the previous events but still has an element of uncertainty regarding the fate of their luggage.

Randomly selecting an ace from a regular deck of 52 playing cards has a higher probability compared to the previous events, as there are four aces in a deck. The likelihood increases further when randomly selecting the queen of hearts, which is only one specific card out of the 52-card deck.

The choice of whether to report the median or mean as a measure of central tendency depends on the shape of the data distribution and the purpose of the analysis.

a) Whether the median or mean would be larger depends on the shape of the distribution of the data. The median is the value that separates the lower half of the data from the upper half, and is a robust measure of central tendency, meaning that it is not greatly affected by outliers or extreme values. On the other hand, the mean is the sum of the data values divided by the number of values, and can be influenced by outliers or extreme values.

In the case of the life expectancies data, if the distribution is roughly symmetrical, with most of the values clustered around the center and relatively few outliers or extreme values, then the mean and median would likely be similar in value. However, if the distribution is skewed to one side, with many values concentrated on one end and relatively few values on the other end, then the mean would likely be larger than the median.

b) The best measure to report depends on the context and the purpose of the analysis. In general, the median is a more appropriate measure of central tendency for skewed distributions, since it is not greatly affected by outliers or extreme values. On the other hand, the mean is more appropriate for symmetrical distributions, since it provides a more accurate representation of the typical value of the data.

In the case of the life expectancies data, it may be useful to report both the median and the mean in order to provide a full picture of the central tendency of the data. However, if there are outliers or extreme values that could significantly affect the mean, it would be more appropriate to report the median as the primary measure of central tendency.

The value of x from the similar triangles is x = 9 and the length of CE of the triangle ACE is CE = 35

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as ΔACE

Let the second triangle be represented as ΔBDC

The measure of side AB = 6

The measure of side BC = x - 5

The measure of side AC = x + 1

The measure of side CD = 14

The measure of side DE = 2x + 3

The measure of side CE = 2x + 17

Now , ΔACE and ΔBDC are similar

So , the corresponding sides of similar triangles are in the same ratio

Substituting the values in the equation , we get

AC / CE = BD / CD

( x + 1 ) / ( 2x + 17 ) = ( x - 5 ) / 14

On simplifying the equation , we get

14x + 14 = 2x² - 10x + 17x - 85

Subtracting 14x + 14 on both sides of the equation , we get

2x² - 7x - 99 = 0

On factorizing the equation , we get

x = 9 or x = -11/2

Substituting the value of x in the equation , we get

The length of line segment CE = 2x + 17

The length of line segment CE = 2 ( 9 ) + 17

The length of line segment CE = 35

Hence , the length of CE is 35
