Answer:
Well to find the mean of the above
take £ as sigma
therefore,
mean= £fx/£f
This simply means the sum of all the numbers divided by the number of members
therefore,
10 + 11+12+13+14+15+16+17+18= 126
And the number of figure present on the number line are 9, therefore 126 divided by 9
giving you a result of 14
Therefore the mean of the above numbers is 14.

I have two bags of counters.
The first bag contains two red counters and one blue counter.
The second bag contains one red counter, one blue counter
and two yellow counters.
I take a counter at random from both bags.
a) What is the probability that the two counters will be the same colour?
b) What is the probability that exactly one of the counters will be red?
Answer:
oooooh Mathswatch.a=3/12 b=7/12
Step-by-step explanation:
a=You need to list all the probability out
There is a total of 24 possibility and 6 of them are the same colour. Simplify it, it becomes 3/12
b= see the photo. (sorry the photo wasn't too good, I am on a computer)
There are a total of 14 combination that has one red counter in it, simplify it, it is 7/12
A) The probability that the two counters will be the same colour is; ¼
B) Probability that exactly one of the counters will be red is; P(exactly one counter is red) = 7/12
We are told that he has 2 bags of counters;
First bag;
- 2 red counters
- 1 blue counter
Second bag;
- One red counter
- One blue counter
- two yellow counters
A) He takes a counter from both bags, probability that they will be same colour is;
RR or BB
Now, P(RR) = ⅔ × ¼ = 2/12
P(BB) = ⅓ × ¼ = 1/12
Thus;
P(both same colour) = 2/12 + 1/12
P(both same colour) = ¼
B) Probability that exactly one of the counters will be red;
The possible combinations in this way that have a red is 14.
Meanwhile total possible combinations is 24.
Thus;
P(exactly one counter is red) = 14/24
P(exactly one counter is red) = 7/12

An online clothing store is offering free shipping on orders over $75 you want to purchase t shirt for $9.85 and a pair of pants for$56.00 the shipping on this order will be 20% of the total should you purchase a second t shirt? Explain your answer
Answer:
Buy Two tshirts and a pair of pants....
Step-by-step explanation:
Total purchase -
$9.85 + $56.00 = $65.85
Shipping charges is 20% -
65.85 * 0.2 = 13.17
Total (including shipping) = $79.02
If you purchace two t shirts and a pair of pants then you dont have to pay for the shipping therefore,
Total purchase will be -
$9.85 + $56.00 + $9.85 = $75.70
Puchasing 2 tshirts will be $3.32 cheaper....
Answer:
You should buy a second t-shirt.
Step-by-step explanation:
The total without shipping comes out to $65.85. Add the 20% shipping by multiplying .20 by the total, $65.85, and you get $65.85 plus $13.17, the total being $79.02. Now, if you added another shirt for $9.85, your total comes out to $75.70, which barely qualifies for free shipping. In other words, yes, you should purchase a second shirt because you would actually save money, almost $4.

Jada is visiting new york city to see the empire state building she is 100 feet away when sge spots it.To see the top she has to look up at an angle of 86.2 dehrees how tall is the empire state building
Answer:
Height of the empire building = 1505.57 ft
Step-by-step explanation:
Jada is visiting new York city to see the empire state building . She is 100 ft away when the she spots it. To see the top she has to look at an angle of 86.2° . The illustration forms a right angle triangle.
The height of the empire can be gotten below.
the adjacent side of the triangle formed = 100 ft
The side we are looking for is the opposite side which is the height of the empire state building. The angle formed is the angle of elevation from the ground to the top which is 86.2°
Using SOHCAHTOA principle the height can be gotten with the tangential degree.
tan 86.2° = opposite/adjacent
tan 86.2° = a/100
a = 100 tan 86.2
a = 100 × 15.0557227245
a = 1505.57227245
a ≈ 1505.57 ft
Height of the empire building = 1505.57 ft

You pick a card at random, put it back, and then pick another card at random.
What is the probability of picking a number less than 3 and then picking a number greater than 1?
Write your answer as a percentage.
__%
Your answer would be 37.5%
For the first card you picked, the probability of picking a number less than 3 is 2/4 = 1/2, because there are 2 cards that are less than 3 and a total of 4 cards.
When picking the second card, it is still out of 4 because you replaced the first one, so the probability of picking a card greater than 1 is 3/4 because there are 3 cards that are greater than 1 out of a total of 4.
Therefore the total probability would be 1/2 × 3/4 = 3/8. To find this as a percentage we just multiply by 100, and this gives us 37.5%.
I hope this helps!
Answer:
You have three card : 1, 2, 3 and 4.
You first pick one card randomly, the probability of picking a number less than 3 is:
P = 2/4
You then pick a second card after putting the first card back, the probability of picking a number greater than 1 is:
P = 3/4
=> The probability of picking a number less than 3 and then picking a number greater than 1:
P = (2/4) x (3/4) = 3/8

what is the relationship between the base of an exponential function and its rate of growth?
Answer:
growth rate is the number of times the base repeats
Step-by-step explanation:
We have that the general form of the exponential function is of the type:
f (x) = a ^ x
where "a" is the base and "x" is the exponent.
Therefore, the relation they keep to this exponent would be the growth rate since it is the number of times that the base is repeated, which means that the higher "x" is, the more times "a" is repeated.
The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.
Exponential functionThe standard exponential function is expressed as y = ab^x
where:
a is the y-interceptb is the ratex is the time taken.The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.

write an equation of the line that passes through the point (4,7) that is parallel to the line y = 3x+1
Explanation:
The given line y = 3x+1 has a slope of 3 as it is in the form y = mx+b
Any line parallel to this given line will also have a slope of 3. Parallel lines have equal slopes but different y intercepts.
Using m = 3 and (x,y) = (4,7), find the value of b
y = mx+b
7 = 3*4+b
7 = 12+b
12+b = 7
b = 7-12
b = -5
We have y = mx+b update to y = 3x+(-5) or y = 3x-5
Plug in x = 4 and you'll have y = 3x-5 turn into y = 7.
Simplify cos[arccsc((2√3)/3)].
Answer:
1/2Step-by-step explanation:
Given the expression cos[arccsc((2√3)/3)]
let y = arccsc((2√3)/3)
Taking cosec of both sides we have;
cosecy = cosec[arccsc((2√3)/3)]
cosecy = (2√3)/3
1/siny = (2√3)/3
sin y = 3/2√3
Rationalizing 3/2√3
= 3/2√3 *√3/√3
= 3√3/2*3
= 3√3/6
= √3/2
siny = √3/2
y = arcsin(√3/2)
y = 60°
Since y = arccsc((2√3)/3) = 60°
cos[ arccsc((2√3)/3)] = cos60°
cos60° = 1/2

El volumen de un cubo ed de 125 cm3. ¿cuantas veces aumentara el volumen de ese cubo si se duplica la medida de su arista?
Answer:
The volume would increase 8 times
Step-by-step explanation:
The volume of a cube is given by the following formula:
Volume = side^3
With a volume of 125 cm3, we have:
125 = side^3
Now, if we double the length of the side, we have that:
New volume = (2*side)^3
New volume = 8*side^3
New volume = 8 * 125 = 1000
So the ratio of the new volume over the old volume is:
New volume / Volume = 1000 / 125 = 8
So the volume increased 8 times.

Mr. Green tells you that a right angle has a hypotenuse of 13 and a leg of 5. She asks you to find the other leg of the triangle. Whats is your answer??
Answer:
Length of leg ⇒ 12
Step-by-step explanation:
Knowing this is a right angle triangle, let us apply Pythagorean Theorem to solve for the length of this other leg, which we can assign as x;
x^2 + 5^2 = 13^2 ⇒ square 5 and 13,
x^2 + 25 = 169 ⇒ subtract 25 from either side of equation,
x^2 = 144 ⇒ Take square root on either side,

John assignments in value of his car overtime the equation for the line of best fit is approximate as Y represents 2.9 X +17.7 where y represents the value in thousands of dollars what values complete the Residual table
Answer:
For the given equation of the line of best fit, the values that complete the table are as follows
An equation for a line of best fit follows the same guidelines as a linear function where 'y' represents the total (value), 'x' represents time (years), -2.9 is the rate, and 17.7 is the starting value. The table indicates that for any year, there is a given value, but what we are solving for is the predicted value. The residual is the different between the given and predicted values. So, for 'a', we need to solve for the 'y' in our equation by replacing 'x' with '1', multiplying by -2.9 and adding 17.7. This gives us 14.8. For 'b', we simply need to subtract the given and predicted values to get a residual of 0.1. For 'c', we again solve for 'y' by replacing 'x' with '3' in our given equation to get 9. And, for 'd' we subtract the given value of 5 and the predicted value of 6.1 to get 1.1.
answer-
a = 14.8
b = 0.1
c = 9
d = -1.1

answer-
a = 14.8
