Answer: Option E is the correct answer; (1 + p⁴) / (1 + p³)
Step-by-step explanation:
P (3 head) = P(first and 3 heads) + P(second coin and 3 heads)
= (1/2)×1³ + (1/2)× p³ = (1/2) × (1 + p³)
therefore P(first coin given 3 heads) = (1/2)×1³/ ((1/2)×(1 + p³))
= 1 / (1 + p³)
Also P( second coin given 3 heads) = p³ /(1 + p³)
therefore P(4th toss in heads given first 3 are heads) will be;
= P(first and 4th toss heads) + P(second and 4th toss heads)
=(1/( 1 + p³ )) × 1 + p³ / (1+p³) × p
= (1 + p⁴) / (1 + p³)
Therefore Option E is the correct answer

Do you guys know this.
Answer:
0.77
Step-by-step explanation:
You solve the inner first, then move to the outer.
Plug in x = 20 for g(x) = [tex]\frac{2x+2}{x-6}[/tex]. It should give you [tex]\frac{42}{14}[/tex], which simplifies to 3.
You then need to solve f(x) with the given value from g(x), which is 3.
Plug in x = 3 for the equation [tex]\sqrt{0.4x^2-x}[/tex], and you should get [tex]\sqrt{0.6}[/tex].
The answer is roughly 0.77.
The fire department has seen an increase in smoke detector sales since 2015. In 2015,
they sold 350 detectors which is up from the previous year by 105%. How many did they
sell in the previous year?
Answer:
Step-by-step explanation:
Given the amount of detectors sold in the current year = 350
percent increment = 105%
To get the amount sold the previous year, we will use the expression;
(105% of x) + x = 350
1.05x = 350 + x
1.05x + x = 350
2.05x = 350
x = 350/2.05
x = 170.7
Hence the amount sold the previous year was 170.7 detectors

What is B^y=x in logarithmic form?
Answer:
The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1

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?
Answer:
David make his first error at Step 3
Step-by-step explanation:
We need to determine the error David made when finding the product of (-2.5)(-8.3)
He did the following steps
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
David made a mistake in Step 3
When we multiply (-1) with (-1) we get + instead of - sign. The correct step 3 would be:
Step 3: =(16.6)(4.15)
Step 4: =20.75
So, David make his first error at Step 3

What is the range of the function represented by the table?
A 2-column table with 5 rows. Column 1 is labeled x with entries 2, 4, 6, 8, 10. Column 2 is labeled y with entries 2.5, 5.0, 7.5, 10.0, 12.5.
{2, 4, 6, 8, 10}
{2.5, 5.0, 7.5, 10.0, 12.5}
{2, 2.5, 4, 5.0, 6, 7.5, 8, 10, 12.5}
{0.0, 0.5}
Answer:
{2.3, 5.0, 7.5, 10.0, 12.5} Option b

The first 6 terms of a sequence are shown below.
96, 48, 24, 12, 6, 3,...
What is the 12th term of the sequence?
Answer:
It would either be (1.5, 1 1/2, or 3/2) - they are all the same value just written differently.
Step-by-step explanation:
going from left to right, you can see the pattern of the sequence is to divide each number by 2.
96/2 is 48; 48/2 is 24; 24/2 is 12; 12/2 is 6; 6/2 is 3
taking that knowledge, you would divide 3 by 2, resulting in 1.5 ; 2/3 ; or 1 1/2

An investment portfolio offers a plan that will increase your holdings 30%
half the time, and lose you 20% the other half. Is this a worthwhile
investment for 1) one year, and 2) for the long term?
Answer:
It is a worthwhile investment for both one year and for the long term.
Step-by-step explanation:
While the investment will obtain in the first half of the year gains of 30%, and in the second half of the year losses by 20%, at the end of the year the benefit obtained by the investment will be greater than 0%. Therefore, both within a year and in the long term, it is a viable and favorable investment, since it will yield positive results at the end of the cycle.
So, for example, an initial investment of $ 100 would operate in the following way:
-First half of the year: 100 x 1.3 = 130
-Second half of the year: 130 - (130 x 0.2) = 104
Thus, at the end of the year a profit of 4% of the initial investment will be obtained.
