Answers
Answer:

0.9
Step-by-step explanation:
The average age of the lizards will be 2 and the standard deviation is 0.81.
What is an average?Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values.
Given that the lizards were randomly selected from the 36 lizards at your local zoo: 1, 2, 2, 1, 3, 3
The average will be calculated as:-
Average = Sum of the data / Number of the data
Average = ( 1 + 2 + 1 + 3 + 3 ) / 6 = 12 / 6 = 2
The standard deviation will be calculated as:-
[tex]\rm \sigma=\sqrt{\dfrac{\sum(x-\mu)^2}{N}}\\\\\sigma=\sqrt{\dfrac{(1-2)^2+(2-2)^2+(1-2)^2+(3-2)^2+(3-2)^2}6[/tex]
[tex]\sigma[/tex] = 0.81
Therefore, the average age of the lizards will be 2 and the standard deviation is 0.81.

The table and equation represent different linear relationships. Which one has the greater rate of change? Explain your reasoning.
Answers
Answer:
The equation y=4x-1 has a greater rate of change
Step-by-step explanation:
to find rate of change for the table, you use [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
so, [tex]\frac{-5-(-7)}{-2-(-3)}[/tex] = [tex]\frac{2}{1}[/tex] = 2
So the rate of change for the table is 2 while the rate of change for the equation is 4. 4>2 so the equation has a greater rate of change.
2c +10 = 30
How can I solve this?
Answers
Step-by-step explanation:
2c+10=30
2c+10−10=30−10
2c=20
2c÷2=20÷2
Answer: c=10
Answer:
10
Step-by-step explanation:
2c + 10 = 30
so we take 10 to the other side to become - 10.
Therefore 2c = 30 - 10
= 20
Divide both sides by the coefficient of c that's 2
2c = 20
c = 10
Winona wants to add the numbers 1 2 + 2 3 + 3 2 . She first added 1 2 and 3 2 , then added the result to 2 3 . What reason supports why Winona can do this?
Answers
Answer:
Associative property
Step-by-step explanation:
Given
½ + ⅔ + 3/2
Required
What reason supports Winona's process?
This question could be better answered, if supported with options; however, since there's none, I'll provide my answer on a general rule.
Winona's process can be supported by associative property of algebra which implies that
a + b + c = (a + b) + c = a + (b + c) = (a + c) + b
So, when Winona added ½ to 3/2, it is represented by a + c
And when she added the result to ⅔, it is represented by (a + c) + b
Hence, we can conclude that Winona applied associative property
A gas cylinder contains 1.00 mol He, 1.90 mol Ne, and 1.10 mol Ar. If the total pressure in the cylinder is 2250 mmHg, what is the partial pressure of each of the components? Assume constant temperature.PHe=
PNe=
PAr=
Answers
Answer:
P_he = 562.5 mmHg
P_ne = 1068.75 mmHg
P_ar = 618.75 mmHg
Step-by-step explanation:
Formula for partial pressure is;
Partial pressure = mole fraction × total pressure
Mole fraction of Helium(He); x_he= 1/(1 + 1.9 + 1.1) = 1/4 = 0.25
Mole fraction of Neon(Ne); x_ne = 1.9/(1 + 1.9 + 1.1) = 1.9/4 = 0.475
Mole fraction of argon; x_ar = 1.1/(1 + 1.9 + 1.1) = 1.1/4 = 0.275
Thus;
Partial pressure of He;
P_he = 0.25 × 2250
P_he = 562.5 mmHg
Partial pressure of Ne;
P_ne = 0.475 × 2250
P_ne = 1068.75 mmHg
Partial pressure of Ar;
P_ar = 0.275 × 2250
P_ar = 618.75 mmHg

3. (f•f•f)(1)
4. (f•f•f•f)(1)
5. (f•f•f•f•f)(1)
Answers
Problem 1
f(x) = x + 1/x
f(1) = 1 + 1/1
f(1) = 1 + 1
f(1) = 2
Answer: 2
============================================
Problem 2
(f o f)(1) = f( f(1) )
(f o f)(1) = f( 2 )
(f o f)(1) = 2 + 1/2
(f o f)(1) = 4/2 + 1/2
(f o f)(1) = 5/2
Answer: 5/2
============================================
Problem 3
(f o f o f)(1) = f( f(f(1)) )
(f o f o f)(1) = f( (f o f)(1) )
(f o f o f)(1) = f( 5/2 )
(f o f o f)(1) = 5/2 + 1/(5/2)
(f o f o f)(1) = 5/2 + 2/5
(f o f o f)(1) = 25/10 + 4/10
(f o f o f)(1) = 29/10
Answer: 29/10
============================================
Problem 4
(f o f o f o f)(1) = f( f(f(f(1)) )
(f o f o f o f)(1) = f( (f o f o f)(1) )
(f o f o f o f)(1) = f( 29/10 )
(f o f o f o f)(1) = 29/10 + 1/(29/10)
(f o f o f o f)(1) = 29/10 + 10/29
(f o f o f o f)(1) = 841/290 + 100/290
(f o f o f o f)(1) = 941/290
Answer: 941/290
============================================
Problem 5
(f o f o f o f o f)(1) = f( f(f(f(f(1)))) )
(f o f o f o f o f)(1) = f( (f o f o f o f)(1) )
(f o f o f o f o f)(1) = f( 941/290 )
(f o f o f o f o f)(1) = 941/290 + 1/(941/290)
(f o f o f o f o f)(1) = 941/290 + 290/941
(f o f o f o f o f)(1) = 885481/272890 + 84100/272890
(f o f o f o f o f)(1) = 969581/272890
Answer: 969581/272890
A function assigns the values. The value of (f•f•f•f•f)(1) is 969581/272890.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
1.)
The value of f(1) for the given function f(x) =x+1/x can be calculated as shown below,
f(x) = x + 1/x
f(1) = 1 + 1/1
= 1 + 1
= 2
2.)
(f · f)(1) = f( f(1) )
Since the value of f(1)=2, therefore, it can be rewritten as,
(f · f)(1) = f(2)
= 2 + 1/2
= 4/2 + 1/2
= 5/2
3.)
(f · f · f)(1) = f( f(f(1)) )
Since the value of f(f(1))=5/2, therefore, it can be rewritten as,
(f · f · f)(1) = f( (f·f)(1) )
= f( 5/2 )
= 5/2 + 1/(5/2)
= 5/2 + 2/5
= 25/10 + 4/10
= 29/10
4.)
(f · f · f · f)(1) = f( f(f(f(1)) )
Since the value of f(f(f(1)))=29/10, therefore, it can be rewritten as,
(f · f · f · f)(1) = f( (f·f·f)(1) )
= f( 29/10 )
= 29/10 + 1/(29/10)
= 29/10 + 10/29
= 841/290 + 100/290
= 941/290
5.)
(f · f · f · f · f)(1) = f( f(f(f(f(1)))) )
Since the value of f(f(f(1)))=29/10, therefore, it can be rewritten as,
(f o f o f o f o f)(1) = f( (f·f·f·f)(1) )
= f( 941/290 )
= 941/290 + 1/(941/290)
= 941/290 + 290/941
= 885481/272890 + 84100/272890
= 969581/272890
Hence, the value of (f•f•f•f•f)(1) is 969581/272890.

Answers
Answer:
At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0
Step-by-step explanation:
At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F.
We can say that −3.6 lie on the LHS of a number line while 43.7 lie on RHS of the number line and 0 at the mid.
43.7°F is above 0 and 3.6°F is below 0.
At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0 . Hence, the correct option is (d).

A rectangular prism has a length of 9 inches and a width of 8 inches. The lateral area is 170 square inches. What is the height of the prism? The height of the prism is inches.
Answers
Answer:
The height of the prism is 5 inches
Step-by-step explanation:
The rule of the lateral area of the rectangular prism is
L.A = 2(L + W) × H, where
L is the length of the base of the prismW is the width of the base of the prismH is the height of the prism∵ A rectangular prism has a length of 9 inches and a width of 8 inches
∴ L = 9 inches
∴ W = 8 inches
∵ The lateral area of it is 170 square inches
∴ L.A = 170 square inches
→ Substitute them in the rule above to find the height of the prism
∵ 170 = 2(9 + 8) × H
∴ 170 = 2(17) × 5
∴ 170 = 34 × H
→ Divide both sides by 34 to find H
∴ 5 = H
∴ The height of the prism is 5 inches.
