The better statistics to use to compare the penguin heights is the median and standard deviation. The correct options are A and B.

Mean is defined as the ratio of the sum of the number of data sets to the total number of data.

The Penguin Heights at City view Zoo (in cm) is:

S = {35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45}

Compute the mean and median of the data:

Mean = ( 35 + 36 + 37 + 38 + 39 + 40 + 41 + 42 + 43 +  44 + 45 ) / 11

Mean = 40

Median = 40

The mean and median are the same. This implies that the height of penguins is normally distributed.

So, either the mean or median could be the best measure of the centre.

One measure of a dataset's spread or dispersion from its average value is its standard deviation. The standard deviation calculates the distribution of values' absolute variability.

The standard deviation increases as the spread or variability of the data set increases, which also increases the magnitude of the value's deviation from the average.

Answer:

\(m_{perpendicular}\) = 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + 6y = - 24 ( subtract x from both sides )

6y = - x - 24 ( divide through by 6 )

y = - \(\frac{1}{6}\) x - 4 ← in slope- intercept form

with slope m = - \(\frac{1}{6}\)

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{1}{6} }\) = 6

Answer:

\(x=5,y=4\)

Step-by-step explanation:

\(2x-3y=-2\)

Add 3y to both sides:

\(2x-3y+3y=-2+3y\)

\(2x=-2+3y\)

Divide both sides by 2:

\(\frac{2x}{2}=-\frac{2+3y}{2}\)

\(x=\frac{-2+3y}{2}\)

Substitute this into the second equation:

\(4* \frac{-2+3y}{2}+y=24\)

\(2\left(3y-2\right)+y=24\)

\(7y-4=24\)

Add 4 to both sides:

\(7y-4+4=24+4\)

\(7y=28\)

Divide both sides by 7:

\(\frac{7y}{7}=\frac{28}{7}\)

\(y=4\)

We know that \(x=\frac{-2+3y}{2}\)

Thus, \(x=\frac{-2+3* \:4}{2}\)

\(x=\frac{10}{2}\)

\(x=5\)

Answer:

\(\Huge \boxed{\text{13.66$\%$}}\)

Step-by-step explanation:

To find the rate, we need to use the following formula:

\(\LARGE \boxed{ \boxed{\text{Rate = $\frac{\text{Portion}}{\text{Base}}$$\times$100}}}\)

Where "Portion" is the part of the whole and "Base" is the whole.

Now, let's plug in the given values:

\(\large \text{Rate = $\frac{\text{50}}{\text{366}}$$\times$100 = 13.66 (Rounded to the nearest tenth of a percent)}\)

Therefore, the rate is 13.66% (rounded to the nearest tenth of a percent).

Answer: 2048

Step-by-step explanation: 1. Write the exponential growth model.

The population of the town doubles every year, so the growth factor is 2. The initial population is 112, so the equation is: P(t) = 112(2)^t where P(t) is the population in year t and t is the number of years since 2014.

2. Estimate the population of the town in 2023. To estimate the population of the town in 2023, we can set t=9, since 2023 is 9 years after 2014. Plugging this into the equation, we get: P(9) = 112(2)^9 = 2048

Therefore, the estimated population of the town in 2023 is 2048.

The triangle which could be drawn as per the given description is only option b. isosceles triangle with measure 20° and 80°.

An acute triangle with sides measuring 7, 4, and 2

In an acute triangle, the sum of the squares of the two shorter sides must be greater than the square of the longest side .

According to the Pythagorean Theorem.

Here, 7² is greater than (4² + 2²).

So this is not possible.

An isosceles triangle with angles measuring 20° and 80°

In an isosceles triangle, two angles are equal, so if two angle measures 20° and 80°,

Then the third angle measures is

180° - 20° - 80°= 80°

Two angles are congruent implies two sides are congruent.

It is possible to form isosceles triangle.

An obtuse triangle with sides measuring 5, 10, and 15

In an obtuse triangle, the longest side is opposite the largest angle.

Sum of squares of two shorter sides is less than square of longest side according to Pythagorean Theorem.

However, 15²is greater than (5²+ 10²),

so this is not possible.

A scalene triangle with angles measuring 110° and 35°

The sum of the angles of any triangle is 180°,

so the third angle must measure

180° - 110° - 35° = 35°.

Two angles are congruent so it is isosceles triangle.

It is not possible to form scalene triangle.

Therefore, the triangle possible to draw as per the given condition is only option b. isosceles triangle with measure 20° and 80°.

Answer:

Most significant digit. That's the same that it's called for any number system.

Step-by-step explanation:

Answer:

y=1/2x + 3

Step-by-step explanation:

The first thing you need to know is that the slope of a perpendicular line is the opposite reciprocal of the other slope. Find the slope of this line, which is -2. The opposite reciprocal is 1/2. So, you know that the perpendicular line is equal to y=1/2x. Plug the x coordinate (4) in for x to have: y=1/2(4). Multiply 4 by 1/2 to get y=2. Since the y coordinate is supposed to equal 5, add 3 to y=2 to get 5. Since 3 is the amount we added, thats where the y intercept will be. Hope this helped!

Answer:

44.16 ; 4.88

Step-by-step explanation:

Recall :

Mean, μ = np

Sample size, n = 96

Sample proportion, p = 0.46

For the mean :

Mean, μ = 96 * 0.46

0.46 * 96 = 44.16

The standard deviation :

σ = √npq

q = 1 - p = 1 - 0.46 = 0.54

σ = √npq = √(96 * 0.46 * 0.54)

σ = √23.8464

σ = 4.88

Answer:

Step-by-step explanation:

C^2= A^2 + B^2

C^2 = (60)^2 + (25)^2

C^2 = 4225

Take the square root of C

C = 65

Answer:

65

Step-by-step explanation:

Use the Pythagorean Theorem to find the length of the hypotenuse.

\(a^2+b^2=c^2\)

I'm assuming that '60' and '25' are measures of the legs, since the question asks to find the hypotenuse.

\(60^2+25^2=c^2\\\rightarrow 60^2=3600\\\rightarrow 25^2 = 625\\3600+625=c^2\\4225=c^2\\\sqrt{4225}=\sqrt{c^2}\\\boxed{65=c}\)

The hypotenuse should measure 65 units.

A=1/2 πr² + 1/2(a+b)h

A=1/2×3.142×7² + 1/2(14+18)10.5

A=1/2×3.142×49 + 1/2×32×10.5

A=76.98+168

A=244.98cm²

Given:

An airport limo service charges riders a fixed charge of $15 plus  $4.00 per mile.

To find:

Distance in miles must a rider go to have an  average cost per mile of $4.60.

Solution:

Let x be the number of miles the rider travel.

Total charges = Fixed charges + Variable charges

According to the question,

Fixed charges = $15

Variable charges = $4x

So,  total charges

\(T=15+4x\)

Divide the total charges by number of miles to get the cost per mile.

\(\text{Cost per mile}=\dfrac{15+4x}{x}\)

Average cost per mile is $4.60.

\(4.60=\dfrac{15+4x}{x}\)

\(4.60x=15+4x\)

\(4.60x-4x=15\)

\(0.60x=15\)

Divide both sides by 0.60.

\(x=\dfrac{15}{0.60}\)

\(x=25\)

Therefore, the required number of miles is 25.
