If you look at the picture, you set it up as part over whole is equal to percent over 100. then you just multiply across.
Answer:
he can make 6 goodie bags
Step-by-step explanation:
Answer:
Two intervals are 63 and 75
Step-by-step explanation:
Given:
Mean of students (μ) = 69 inches
Standard deviation (σ) = 3 inches μ
Find:
Interval of heights (95%) using empirical rule
Computation:
Interval of heights (95%) using empirical rule:
⇒ μ – 2σ = 69 - 2(3)
⇒ μ – 2σ = 69 - 6
⇒ μ – 2σ = 63
⇒ μ + 2σ = 69 + 2 (3)
⇒ μ + 2σ = 69 + 6
⇒ μ + 2σ = 75
Two intervals are 63 and 75
The question is incomplete. Here is the complete question.
A triangle has rotation symmetry that can take any of its vertices to any of its other vertices. Select all conclusions that we can reach from this
a. All sides of the triangle have the same length
b. All angles of the triangle have the same measure
c. All rotations take one half of the triangle to the other half of the triangle.
Answer: a. All sides of the triangle have the same length
b. All angles of the triangle have the same measure
Step-by-step explanation: When an object is rotated on its own axis, the shape looks the same.
If a triangle is rotated, some of its vertices will be in different positions but its sides will be the same length and the angles will have the same measure.
