5. A study of a population of 1,200 frogs revealed that 12 out of every 180 frogs in the population
have spots on their back. Based on the results of this study, how many frogs in the population do
NOT have spots on their back?
A. 80 C. 1,280
B. 168 D. 1,120
Answer:
1,280
Step-by-step explanation:
prob(spots) = 12/180 = 1/15
so of the 1200 frogs, (1/15)(1200) should have spots, so ..
how many should not have frogs ?
or
prob(not spots) = 14/15
number who don't have spots = (14/15)(1200) = 1,280
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?
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
Given h(x) = 2x - 3 , solve for when h(x) = - 3 .
Answer:
h(x)=-3;x=0
Step-by-step explanation:
When given h(x), you are in effect, being given the output of the function.
So, placing h(x)=-3 in place for h(x)
We get
-3=2x-3
Where -3+3=2x
0=2x
x=0
So, x=0

The semicircle that is added on to the rectangle can be translated to fit into the slot where a semicircle has been removed (both semicircles are congruent as they have the same diameter). This leaves us with a plain rectangle, with area b * h, or 8 * 10, or 80.
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=
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
A ball is thrown straight up into the air from the top of a building standing at 50 feet with an initial velocity of 65 feet per second the height of the ball in feet can be modeled by the following function: h(t)=-16t^2++16t+96 When does the ball reach its maximum height?
Answer:
0.5 seconds (at 100 feet in the air).
Step-by-step explanation:
So, the height of the ball can be modeled by the function:
[tex]h(t)=-16t^2+16t+96[/tex]
Where h(t) represents the height in feet after t seconds.
And we want to find its maximum height.
Notice that our function is a quadratic.
Therefore, the maximum height will occur at the vertex of our function.
The vertex of a quadratic function in standard form is given by the formula:
[tex](-\frac{b}{2a}, f(-\frac{b}{2a}))[/tex]
In our function, a=-16; b=16; and c=96.
Find the x-coordinate of the vertex:
[tex]x=-\frac{(16)}{2(-16)}=1/2[/tex]
So, the ball reaches its maximum height after 0.5 seconds of its projection.
Notes:
To find it’s maximum height, we can substitute 1/2 for our function and evaluate. So:
[tex]h(1/2)=-16(1/2)^2+16(1/2)+96[/tex]
Evaluate:
[tex]h(1/2)=-4+8+96=100[/tex]
So, the ball reaches its maximum height of 100 feet 0.5 seconds after its projection.

D. Evaluate each of the following. (5 points)
Let f(x) =x+1/x
1. f(1)
2. (f •f)(1)
3. (f•f•f)(1)
4. (f•f•f•f)(1)
5. (f•f•f•f•f)(1)
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.

I need help identifying the independent and dependent variables, also are they continuous or discrete. I need help can someone help me please?
thanks ;)
Answer:
s = independent variable, P(s) = dependent variable
Step-by-step explanation:
s = discrete because you need a certain value for shirts. For instance, 1,2,3, etc... you cannot make profit off half a shirt or a quarter of a shirt.
P(s) = continuous because profits doesnt have to be an exact value. For instance, you can make a profit of $12.65
Insurance companies A and B each earn an annual profit that is normally distributed with the same positive mean. The standard deviation of company A’s annual profit is one half of its mean. In a given year, the probability that company B has a loss (negative profit) is 0.9 times the probability that company A has a loss.Calculate the ratio of the standard deviation of company B’s annual profit to the standard deviation of company A’s annual profit.(A) 0.49(B) 0.90(C) 0.98(D) 1.11(E) 1.71
Answer:
C. 0.98
Step-by-step explanation:
Let x be the mean of Company A and B annual profit and x/2 and y are standard deviation of Company A and B annual profit.
P(B<0) = 0.9*P(A<0)
P(Z<(0-x)/y) = 0.9*P(Z<(0-x)/(x/2))
P(Z<-x/y) = 0.9*P(Z<-2)
P(Z<-x/y) = 0.0205
x/y =2.04
Or y/x = 1 /2.05
y/x =0.49
Ratio of the standard deviation of company B annual profit to the standard deviation of company A annual profit =y/(x/2)
= 2*(y/x)
= 2*0.49
= 0.98

d
At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0
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).

Sarah was thinking of a number. Sarah doubles it, then adds 4 to get an answer of 97.7. What was the original number?
Suppose that Sears has a sale on a portable DVD player. The DVD player was originally
$80. However, the DVD player was marked down at a 25% discount, but today Sears is
having a special 25% off everything in the store, even sales items. What would the cost of the item be today after both discounts? (Explain how you got your answer)
Answer:
The answer would be $40.
Step-by-step explanation:
You take the first 25% off and add it to the other 25% off, which would equal 50% off. After that you take 50% off for $80, which would be $40 because half of $80 is $40.

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.
