OO
оооо
35 36 37 38 39 40 41 42 43 44 45
35 36 37 38 39 40 41 42 43 44 45
O A. Median and standard deviation
O B. Mean and standard deviation
C. Median and IQR
OD. Mean and IQR
SUB
Answer:
The correct options are A and B.
Step-by-step explanation:
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:
[tex]\text{Mean}=\frac{1}{n}\sum X\\\\=\frac{1}{11}\times [35+36+37+38+39+40+41+42+43+44+45]\\\\=40[/tex]
[tex]\text{Median}=[\frac{n+1}{2}]^{th}obs.\\\\=[\frac{11+1}{2}]^{th}obs.\\\\=6^{th}obs.\\\\=40[/tex]
The mean and median are same.
Tis implies that the height of penguins are normally distributed.
So, either the mean or median could be the best measure of center.
Standard deviation is one of the measure of dispersion or spread of a dataset from the average value of the dataset. The standard deviation measures the absolute variability of the distribution of values.
The higher the spread or variability in the data set, the greater is the standard deviation value and thus greater will be the magnitude of the deviance of the value from their average.
Thus, the correct options are A and B.
David made an error when determining the product of (–2.5)(–8.3). Step 1: (–2.5)(–8.3) = (–8.3)(–2.5) Step 2: = (–8.3)(–2) + (–8.3)(–0.5) Step 3: = (–16.6) + (–4.15) Step 4: = –20.75 In which step did David make his first error? Step 1 Step 2 Step 3 Step 4
Answer:
Step 3.
Step-by-step explanation:
We need to tell the incorrect step in the given problem for the product of (–2.5)(–8.3)
Step 1. (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2:
We can write -2.5 = -(2+0.5)
(–8.3)(-(2+0.5)) = (–8.3)(-2)+(-8.3)(-0.5)
= 16.6 + 4.15
Step 3.
= 20.75
He has done an error in step 3. It should be 16.6 + 4.15 instead of (–16.6) + (–4.15). As a result, he get incorrect answer.
Answer:
it is step 3

If p represents doubling the dimensions of a rectangle and q represents the area increasing by a factor of 4, which are true? Select two options.
p → q represents the original conditional statement.
~p → ~q represents the inverse of the original conditional statement.
q → p represents the original conditional statement.
~q → ~p represents the converse of the original conditional statement.
p → ~q represents the contrapositive of the original conditional statement.
Answer:
p → q represents the original conditional statement.
Step-by-step explanation:
In the case when p represents the dimensions that is double of a rectangle while on the other hand the q represent the area i.e. increased by a factor of 4
So this both shows the conditional statement i..e real
where,
P termed as hypothesis
And, q termed as a conclusion
Therefore
The first option is correct

Read the problem to choose the correct method, then solve. A farmer buys a tractor for $50,000. If the tractor depreciates 10% per year, use an exponential function to find the value of the tractor in 7 years. AD CO Exponential Growth, $97,435.86 Exponential Decay, $23,914.85 Exponential Growth, $315,000 Exponential Decay, 21,523.36
Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:
[tex]y=a\cdot (1-r\%)^{t}[/tex]
Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:
[tex]y=a\cdot (1-r\%)^{t}[/tex]
[tex]=50000\times (1-0.10)^{7}\\\\=50000\times 0.4782969\\\\=23914.845\\\\\approx 23914.85[/tex]
Thus, the correct option is, Exponential Decay, $23,914.85.

2x+y=10 Find one non solution and solution. EXPAIN plz help i have a timed test ill make brainliest.
Answer:
x=20-y
y=20-x
Step-by-step explanation:
divide by 2 on both sides: x+y=20
to find x, subtract y:
x=20-y
to find y, subtract x:
y=20-x
nothing else can be done unless you know either y or x.
Ivan and Polina have each drawn a conclusion about multiplying negative fractions. Ivan: The product of an even number of negative fractions is always positive. Polina: The product of an odd number of negative fractions is always negative. Whose conclusion is correct? Ivan only Polina only both Ivan and Polina neither Ivan or Polina
Answer:
Both are correct
Step-by-step explanation:
To check the validity of their statements, we shall be using direct examples
For Ivan , we can have an example of his assertion as follows;
-1/2 * -1/3 = 1/6
For Polina, we can have
-1/2 * -1/3 * -1/4 = -1/24
We can see from the above that both of them got their opinions correctly as there are no exceptions to the above
Answer:
both Ivan and Polina

The measure of angle 1 is (3x + 10)° In the measure of angle 4 is (4x - 15)°
What is the measure of angle 7?
∠1 = ∠4 ( vertically opposite angles )
Then :-
[tex]3x + 10 = 4x - 15[/tex]
[tex]10 = 4x - 15 - 3x[/tex]
[tex]10 = 1x - 15[/tex]
[tex]1x - 15 = 10[/tex]
[tex]1x = 10 + 15[/tex]
[tex]1x = 25[/tex]
Which means :-
∠1 =
= 3x + 10
= 3 × 25 + 10
= 75 + 10
= 85°
∠4 =
= 4x - 15
= 4 × 25 - 15
= 100 - 15
= 85°
Then :-
∠7 = ∠6
∠6 + ∠4 = 180° ( interior angles on the same side of transversal )
∠6 + 85 = 180°
∠6 = 180 - 85
∠6 = 95°
As ;
∠6 = ∠7
∠7 = 95°Therefore , angle 7 = 95° .Answer:
95
