Answer:
120
Step-by-step explanation:
boys : girls
8 : 5
x : 75
to find x, take 75 and divide it by 5:
75 ÷ 5 = 15
(you do this to determine how you can go from 5 to 75)
take the qoutient and multiply it by 8:
15 × 8 = 180

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
Rob is saving to buy a new MP3 player. For every $12 he earns babysitting, he saves $9. On Saturday, Rob earned $36 babysitting. How much money did he save?
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
So, he saved $27

Suppose ABCD is a rhombus with AB = 12 inches. The midpoints of its sides are joined to form a quadrilateral. What type of quadrilateral is formed?
Answer:
A rectangle
Step-by-step explanation:
The given parameters are;
The quadrilateral ABCD is a rhombus;
The length of the sides of the rhombus = 12 inches
The lengths of the sides of a rhombus are equal
The opposite interior angles of the rhombus are equal
The length of each midpoint from the vertex = 12 in./2 = 6 in.
Therefore, we have;
The line joining the midpoints form a quadrilateral with the length of the opposite sides equal
The sum of the interior angles of the rhombus = 180°
From the diagram created with Microsoft Visio, we have;
4·a + 4·b + 360 = 4 × 180 = 360 + 360
4·a + 4·b = 360
a + b = 90°
We have;
The interior angles of the quadrilateral formed = x
a + b + x = 180° Sum of angles on a straight line
∴ x = 180° - (a + b) = 180° - 90° = 90°
x = 90°
Therefore, the interior angles of the quadrilateral formed = 90°
The quadrilateral formed having equal opposite sides, and all interior angle of 90° each is a rectangle

In an arboretum, the heights of five trees were 21 feet, 31 feet, 36 feet, 28 feet,
and 26 feet. What would be the height of the sixth tree if the mean height of the
six trees was 28 feet?
Answer:
26
Step-by-step explanation:
(21+31+36+28+26+x)/6=28
21+31+36+28+26+x= 28×6
142+x =168
x=168-142
x=26

Answer:
B. Getting Faster
Step-by-step explanation:
A. is incorrect, if it was getting slower it would be going the opposite direction.
C. is incorrect, it is not moving at a constant speed, the speed changes a couple times but still gets faster.
D. is incorrect, because it is very clearly moving. If it wasn't moving the line would be flat.

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

The dimensions of a lawn shaped like a trapezoid are given in meters. 18 meters, 4 meters, 5 meters, 12 meters. What is the area of the lawn in square meters?
Answer:
the area of the lawn in square meters is 60 meters^2
Step-by-step explanation:
The computation of the area of the lawn in square meters is shown below
= 12 meters × 5 meters
= 60 meters ^2
Here we multiply the two sides so that the area of the lawn could be come
Hence, the area of the lawn in square meters is 60 meters^2

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.
