The equation that represents the amount saved is T(n) = 3 * (2^n), and the total amount saved in 5 weeks is $186
How to determine the sum of total amount?The statement is given as:
raise $2 to the number of weeks he has been working, multiply it by 3,
Let the number of weeks be n.
So, we have:
T(n) = 3 * (2^n)
For week 1 to 5, we have:
T(1) = 3 * (2^1) = 6
T(2) = 3 * (2^2) = 12
T(3) = 3 * (2^3) = 24
T(4) = 3 * (2^4) = 48
T(4) = 3 * (2^5) = 96
The sum is then calculated as:
Sum = 6 + 12 + 24 + 48 + 96
Evaluate the sum
Sum = 186
Hence, the total amount saved in 5 weeks is $186

The value of the P(2 < X ≤ 4) is 0.14 if the probability of P(x =3) is 0.10 and P(x = 4) is 0.04.
What is a normal distribution?It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We have a probability distribution shown in the table:
P(2 < X ≤ 4)
We have to find the probability between 2 and 4
P(2 < X ≤ 4) = P(x =3) + P(x = 4)
From the table
P(x =3) = 0.10
P(x = 4) = 0.04
P(2 < X ≤ 4) = 0.10 + 0.04 = 0.14
Thus, the value of the P(2 < X ≤ 4) is 0.14 if the probability of P(x =3) is 0.10 and P(x = 4) is 0.04.

Which coordinates identify a location north of a city that has a latitude of 38. 0°n and a longitude of 25. 0°w?.
Using translation concepts, y-coordinates greater than 38 identify a location north of the city.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Considering latitude and longitude, the coordinates of a city are given as follows:
(LON, LAT).
Hence, the given city has coordinates given by:
(25, 38)
As we move north, the latitude increases, hence, y-coordinates greater than 38 identify a location north of the city.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 4² = 9²
x² + 16 = 81 ( subtract 16 from both sides )
x² = 65 ( take square root of both sides )

what is f(x)=x^2 transformed 3 units to the left
Answer:
Equation:
f(x) = (x + 3)^2
Graph: see image
Step-by-step explanation:
Translation just means shift or slide. To show a LEFT shift in the equation, go in close to the x, inside the parenthesis with the x, for LEFT shift, insert +3.
Left and right shifts might be the opposite of what you may think. Minus a number shifts right and plus a number shifts left.

The student council sets up a booth to sell bracelets for $2.50 each and a booth to sell necklaces for $5 each. A $50 donation is made at the booth selling bracelets. The student council decides to close the booths when the amount of money collected is the same.
The students council sold 20 bracelets and 10 necklesses.
What is division?The division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic,
here the number of the bracelets sold will be
[tex]N_{B}=\dfrac{50}{2.5}=20[/tex]
Number of the necklesses sold will be

triangle ABC has a perimiter of 22cm
ab=8cm
bc=5cm
by claculation deduce whether triangle abc is a right angle triangle
Answer:
ABC is not a right angled triangle.
Step-by-step explanation:
Step 1: Given the perimeter of ΔABC = 22 cm, sides AB = 8 cm and BC = 5 cm. Find the side AC.
Perimeter = AB + BC + AC
⇒ AC = 22 - (8 + 5) = 22 - 13 = 9 cm
Step 2: Find whether the triangle is right angled using Pythagoras Theorem which is Hypotenuse² = Side² + Base²
AC² = AB² + BC²
⇒ AC² = 9² = 81
⇒ AB² + BC² = 8² + 5² = 64 + 25 = 89
∴ AC² ≠ AB² + BC²
⇒ ΔABC is not a right angled triangle.
If m varies directly with t, and m = 4 when t = 12, what is the value of t when m = 12?
O4
O20
O24
O36
Answer:
t = 36
Step-by-step explanation:
given that m varies directly with t then the equation relating them is
m = kt ← k is the constant of variation
to find k use the condition m = 4 when t = 12 , then
4 = 12k ( divide both sides by 12 )
[tex]\frac{4}{12}[/tex] = k , that is
k = [tex]\frac{1}{3}[/tex]
m = [tex]\frac{1}{3}[/tex] t ← equation of variation
when m = 12 , then
12 = [tex]\frac{1}{3}[/tex] t ( multiply both sides by 3 to clear the fraction )
36 = t

Step-by-step explanation:
Total = 12+17+14 = 43
Without replacement:
C(12,5) / C(43,5) = (12!/5!*7!) / (43!/5!*38!) = (12*11*10*9*8) / (43*42*41*40*39)
= 95040 / 115511760
= 0.00082
