A batsman scored the following number of runs in six innings:
35, 30, 45, 65, 44, 21. Calculate the mean runs scored by him in
(a) 39
(b) 38
(c) 37
(d) 40
Answer:
D
Step-by-step explanation:
The mean or average is calculated by summing each element and then dividing by the number of elements.
We have: 35, 30, 45, 65, 44, and 21.
There are six elements in total.
We find the sum by adding. Hence:
[tex]35+30+45+65+44+21=240[/tex]
We will now divide by 6, the number of elements:
[tex]240/6=40[/tex]
Therefore, the mean runs scored by the batsman is 40.
Hence, our answer is D.

Alice solves every puzzle with probability 0.6 , and Bob, with probability 0.5 . They are given 7 puzzles and each chooses 5 out of the 7 puzzles randomly and solves them independently. A puzzle is considered solved if at least one of them solves it. What is the probability that all the 7 puzzles happen to be solved by at least one of them
Answer:
0.021943
Step-by-step explanation:
Alice solves every puzzle with a probability of 0.6
Bob solves every puzzle with a probability of 0.5
Number of puzzles given = 7
The probability of a puzzle been solved by either Alice or Bob
P = P( A U B ) = P( A ) + P( B ) - P( A n B )
= 0.6 + 0.5 - ( 0.6 * 0.5 ) = 0.8
probability of all 7 puzzles solved = (P( A ))^2 * ( P )^3 * (p(B))^2
= ( 0.6 )^2 * (0.8)^3 * (0.5)^2 = 0.04608
Finally determine the P ( choosing 5 out of 7 for both such that all the 7 are chosen )
attached below is the remaining part of the solution
Helppp meeeeeee asappppppp
Answer:
9.2
Step-by-step explanation:
So the 14 can be divided equally on both sides by the fact that the line cutting it at right angle bisects it.
Thus having 6 and 7 as the two shorter sides of a right angled triangle will help us get the radius( hypotenuse in this case) using the square root of the sum of the squares of both six and 7, the Pythagoras theory.
this leads to 9.2 as our answer
A gym charges each member $100 for a membership fee and $30 per month after that. How much money will a member spend after 6 months
Answer:
280
Step-by-step explanation:
Month 1: 100 + 30 = 150
Month 2: +30
Month 3: +30
Month 4: +30
Month 5: +30
Month 6: +30
Total: 280
Hope this helps!
Answer:
$280
Step-by-step explanation:
For this problem, we simply need to take the initial cost of membership and add that to the reoccurring cost from a time period, in this case, 6 months. So let's make an equation to represent this.
The initial cost is $100
The per month cost is $30
Total cost after 6 months = Inital cost + Per Month Cost * 6 months
Total cost = $100 + $30 * 6
Total cost = $100 + $180
Total cost = $280
Thus, a member will spend $280 after 6 months on the membership.
Cheers.
Find two real numbers that have a sum of 8 and a product of 13
Answer:
The two numbers are 5.73 and 2,27
Step-by-step explanation:
Let the two numbers be x and y
[tex]x + y = 8[/tex]
[tex]xy = 13[/tex]
Make x the subject in the first equation
[tex]x = 8 - y[/tex]
Substitute 8 - y for x in the second equation
[tex](8-y)*y = 13[/tex]
Open brackets
[tex]8y - y^2 = 13[/tex]
Equate to 0
[tex]y^2 - 8y + 13 = 0[/tex]
Solve using quadratic formula
[tex]y = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 1[/tex] [tex]b = -8[/tex] [tex]c = 13[/tex]
So:
[tex]y = \frac{-(-8) \± \sqrt{(-8)^2 - 4*1*13}}{2*1}[/tex]
[tex]y = \frac{8 \± \sqrt{64 -52}}{2}[/tex]
[tex]y = \frac{8 \± \sqrt{12}}{2}[/tex]
[tex]y = \frac{8 \± 3.46}{2}[/tex]
Split
[tex]y = \frac{8 + 3.46}{2}[/tex] or [tex]y = \frac{8 - 3.46}{2}[/tex]
[tex]y = \frac{11.46}{2}[/tex] or [tex]y = \frac{4.54}{2}[/tex]
[tex]y = 5.73[/tex] or [tex]y = 2.27[/tex]
Recall that
[tex]x = 8 - y[/tex]
When [tex]y = 5.73[/tex]
[tex]x = 8 - 5.73[/tex]
[tex]x = 2.27[/tex]
When [tex]y = 2.27[/tex]
[tex]x = 5.73[/tex]
Hence, the two numbers are 5.73 and 2,27

Is 9, 5, 12, 11 solutions to 2w > 18?
All solutions are larger than 9
=========================================
Explanation:
Divide both sides by 2 and we get
2w > 18
2w/2 > 18/2 .... dividing both sides by 2
w > 9
Any number larger than 9 can replace w, and we'll get a true statement.
For instance, if we tried w = 12, then,
2w > 18
2*12 > 18
24 > 18
Which is true since 24 is indeed larger than 18.
On the flip side, if we tried w = 5, then,
2w > 18
2*5 > 18
10 > 18
which is not true because 10 is actually smaller than 18.
-------------------------
So again, the inequality 2w > 18 solves to w > 9
This shows all solutions are larger than 9.
If we can only pick values from the set {9,5,12,11}, then the solutions are 11 and 12 since they are larger than 9.
A triangle with an area of 10 square meters has a height of 4.5 meters. A similar triangle has an area of 90 square meters. What is the height of the larger triangle?
A) The ratio of the area of the small triangle to the area of the larger triangle is _:_
B) The ratio of the side length of the small triangle to the side length of the larger triangle is _:_
Answer:
h = 40.5 m
A) 1 : 9
B) 1 : 3
Step-by-step explanation:
Let the height of the larger triangle be h
Therefore,
[tex] \frac{10}{90}= \frac{4.5}{h}\\\\
\frac{1}{9}= \frac{4.5}{h}\\\\
h = 9\times 4.5\\\\
h = 40.5\:m\\[/tex]
A)
The ratio of the area of small triangle to the large triangle
[tex] =\frac{10}{90}=\frac{1}{9}=1 : 9[/tex]
B)
The ratio of the side length of small triangle to the side length of large triangle
[tex] =\sqrt{\frac{10}{90}} =\sqrt {\frac{1}{9}} =1 : 3

Find the length of side x in simplest radical form with a rational denominator.
Answer:
[tex] x = \frac{\sqrt{6}}{2} [/tex]
Step-by-step explanation:
Reference angle = 45°
Opposite side = x
Hypotenuse = √3
Use the following trigonometric ratios formula to find x:
[tex] sin(\theta) = \frac{opp}{hyp} [/tex]
Plug in the values
[tex] sin(45) = \frac{x}{\sqrt{3}} [/tex]
Multiply both sides by √3
[tex] \sqrt{3}*sin(45) = x [/tex]
[tex] \sqrt{3}*\frac{\sqrt{2}}{2} = x [/tex]
[tex] \frac{\sqrt{3*2}}{2} = x [/tex]
[tex] \frac{\sqrt{6}}{2} = x [/tex]

An industry consists of three firms with sales of $380,000, $805,000, and $425,000.
a. Calculate the Herfindahl-Hirschman index (HHI). Instruction: Round to the nearest integer.
b. Calculate the four-firm concentration ratio (C4).
c. Based on the FTC and DOJ Horizontal Merger Guidelines described in the text, is the Department of Justice likely to attempt to block a horizontal merger between two firms with sales of $380,000 and $425,000?
The Herfindahl–Hirschman Index, or "HHI," is a widely used indicator of market concentration. The HHI is derived by squaring each rival firm's market share and then adding the obtained figures together.
What is the solutions to the required calculations?(a) Total market ($'000) = 380 + 805 + 425 = 1,610
Firm 1 share = 380/ 1,610x 100 = 23.60%Firm 2 share = 805 / 1,610 x 100 = 50.00%Firm 3 share = 425 / 1,610 x 100 = 26.40%HHI = (23.60)² + (50.00)² + (26.40)² = 3753.92
(b) Since there are only 3 firms in market, four-firms concentration ratio will be 100% or 1
(c) Total revenue share of the two firms = (380+ 425) / 1440 x 100 = 55.90%
Post-merger HHI = (55.90)² + (50.00)² = 5624.81
This merger will, in fact, be stopped. This is because the regulation deems any HHI exceeding 1,800 after a merger to be a highly concentrated market, and so this merger will most likely be blocked.
