The general term of a sequence is given by an = 7+3 (n − 1) for n > 1.
Which recursive formula defines this sequence?
Answer:
The fifth term is 8.
Step-by-step explanation:
Give n=5 in the general term
T 5=3(5)-7 = 15–7 =8
Another method
Tn = 3n - 7
T 1 = 3(1)-7 = -4
T 2 = 3(2) -7= -1
d= t 2 - t 1 = -1 -(-4)=3
a = -4 d=3
Tn = a + (n-1)d =
T 5 = a + (5–1)d = a +4 d = -4 +4(3)= 8
ivan and tanya share £150 in the ratio of 4:1 work out how much more ivan gets than tanya
Step-by-step explanation:
Because of the 4:1 ratio, the cumulative number of pieces taken into account in that ratio is 4 + 1 = 5.
There is a total amount of money of $150 and 5 pieces.
150/5 = $30 is a single component number.
We know that Ivan consists of four pieces, while Tanya consists of one piece of $120 and 30.
As a result, we now split the amount of Ivan into the amount of Tanya: Ivan has 4 times more than Tanya, so Ivan has 4 times more money.
Hope that works!
Answer:
See below
Step-by-step explanation:
Ratio = 4 : 1
Let
Ivan's share = 4x
Tanya's share = 1x
So,
4x + 1x = £ 150
5x = 150
Divide both sides by 5
x = 150 / 5
x = 30
So,
Ivan's share = 4(30) = £ 120
Tanya's share = 1(30) = £ 30
Also,
Ivan has £ 90 more than that of Tanya.

A shopkeeper decided to make equal rate of profit in each of fancy items. If he sold a jacket costing Rs 4400 for Rs 5060 at what price did he sell the shoes which was purchased for Rs 3420
Answer:
RS 3933
Step-by-step explanation:
cost price = RS4400
selling price =RS5060
now,
profit amount = selling price - cost price
= RS5060 -RS4400
= RS660
profit %= profit amount / cost price * 100%
= RS 660 / 4400 * 100
= RS 15%
case II
profit % =15%
selling price = RS 3420
now,
profit amount = p% of cp
=15/ 100 *3420
=RS 513
selling price = cp +profit amount
= 3420+513
=RS 3933
Luke is designing a scale model of a clock tower. The design of the front of the tower is shown below.
A figure can be broken into a triangle and rectangle. The rectangle has a base of 200 millimeters and height of 50 millimeters. The triangle has a base of 50 millimeters and height of 100 millimeters.
What will be the area of the front face of his model?
2,500 square millimeters
10,000 square millimeters
12,500 square millimeters
15,000 square millimeters
The answer is 2,500. You must multiply both of the equations and add them together. The answer will be 2500.
Answer:
Answer:
Option B - 10,000 square millimeters
Step-by-step explanation:
From the image attached, we see that the dimensions of the front of the tower are;
Length; L = 200 mm
Width; w = 50 mm
Now, this front face takes the shape of a rectangle.
Area of rectangle = Length x width
Thus, plugging in the values of length and width, we will get;
Area of front face = 200 x 50
Area of front face = 10,000 square millimeters

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.
The expected value of the winnings from a game will be [tex]2.96[/tex] .
What is Probability ?Probability is the ratio of the number of possible outcomes to the total number of outcomes.
we have,
Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]
Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]
So,
To find the expected value,
Now,
Multiply payout values with its probability and sum these values,
i.e.
Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]
[tex]=0+0.2+0.76+1+1[/tex]
Expected value [tex]=2.96[/tex]

Step-by-step explanation:
You can see that it is moved 8 places to the right which represents x (the first number in your coordinate pair). It also moves 3 places above which represents the y (the second number in the coordinate pair).
You can always remember that x goes before y when writing a coordinate pair by the alphabetical order x, y, z..- X goes before Y!
