Answer:
2.25%
Step-by-step explanation:
I = Prt
Given:
I = 540
P = 8000
t = 3
Solve for r:
I = Prt
r = I/(Pt)
r = 540/(8000 * 3)
r = 540/24000
r = 0.0225
Rate in percentage form:
0.0225 * 100 = 2.25%

Step-by-step explanation:
p = 0.78
1 - p = 0.22
P(x = 3)
Using the binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 3) = 5C3 * 0.78^3 * 0.22^2
P(x = 3) = 10 * 0.78^3 * 0.22^2
P(x = 3) = 0.2297
how do you write the equation of a line in slope intercept form looking at a table?
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept
1) Determine the slope (m)
To find the slope, take two points from the table, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] and plug them into the following equation to solve for m:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug m into [tex]y=mx+b[/tex] .
2) Determine the y-intercept (b)
Take any point given in the table and plug them into [tex]y=mx+b[/tex] (along with the slope that you solved for earlier) as [tex](x,y)[/tex]. Solve for b. Plug b back into [tex]y=mx+b[/tex] along with the slope.

Calculate the area of triangles using two different methods. figures are now drawn to scale.
Answer:
the formula is base times hight divided by two so use the formula to sovle the problem
Step-by-step explanation:
The area of the triangles given are 52.5 feet² and 369 inches² respectively.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
The basic formula to calculate the area of a triangle is,
Area = [tex]\frac{1}{2}[/tex] × base × height
1. Base = 12 + 3 = 15 feet
Altitude/height = 7 feet
Area = [tex]\frac{1}{2}[/tex] × 15 × 7 = 52.5 feet²
2. Calculating the area of two separate triangles and then adding it,
Area = ([tex]\frac{1}{2}[/tex] × 32 × 18) + ([tex]\frac{1}{2}[/tex] × 9 × 18)
= 288 + 81
= 369 inches²
Hence the area of the two figures is 52.5 feet² and 369 inches² respectively.

In order to find the answer, first you have to add up the time she spent in each activity to find the amount of minutes she had been at home when she finished:
1+15+32+45=93
Now, you can express the 93 minutes in hours considering that one hour has 60 minutes. According to this, Emily had been home for 1 hour and 33 minutes (93-60=33).

Which one should I pick?
Answer:
x = 7, y = 16
Step-by-step explanation:
From the diagram shown;
2x+5 = x+12
collect the like terms
2x-x = 12 - 5
x = 7
Similarly, y - 4 = x+5
y-4 = 7+5
y - 4 = 12
y - 12+4
y = 16
hence x = 7, y = 16

Answer:
$27
Step-by-step explanation:
Set up a proportion where x is the amount of money he saved:
[tex]\frac{12}{9}[/tex] = [tex]\frac{36}{x}[/tex]
Cross multiply and solve for x:
12x = 324
x = 27
