Answer:
80%
Step-by-step explanation:
Step 1: Add the given data
588 + 147 = 735
Step 2: Divide the number of students who bought a school shirt by the total number of students
588 ÷ 735
= [tex]\frac{735}{588}[/tex]
= 0.8
Step 3: Convert the decimal to fraction
0.8 = 80% (Move the zero 1 place behind the number and remove the ".")
Or
0.8 × 100 = 80%
Therefore, 80% of students bought a school shirt.
which of these figures has rotational symmetry?
Answer: Choice C
We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.
The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. The correct option is C.
What is Rotational Symmetry?The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. When turned 180 degrees or with specific angles, clockwise or anticlockwise, many geometrical forms appear to be symmetrical. Examples include squares, circles, hexagons, and more.
The shape that has a rotational symmetry is option C, which is a parallelogram.
Hence, the correct option is C.

why is the order you use to name polygons important when writing a congruency statement?
Answer:
When stating that two triangles are congruent, use a congruence statement. The order of the letters is very important, as corresponding parts must be written in the same order. Notice that the congruent sides also line up within the congruence statement. One congruence statement can always be written six ways.

Step-by-step explanation:
Given the parabolic equation is in the form of (y-k)²=4p(x-h), this is a horizontal parabola with a vertical directrix at x=h-p where (h,k) is the vertex and the focus is (h+p,k). Since p=2, then the directrix is x=3-2=1. The vertex would be (h+p,k) -> (3+2,2) -> (5,2). Refer to the graph.

A factory inspector found flaws in 3 out of 18 wooden boxes what is the experimental probability that the next wooden box will be flawed
A factory inspector found flaws in 3 out of 18 wooden boxes. What is the experimental probability that the next wooden box will be flawed?
Write your answer as a fraction or whole number.
-------------------------------------------------------------------------------------------------------------
Remember, The experimental probability is the number of times an event occurs out of the total number of trials.
-------------------------------------------------------------------------------------------------------------
Flawed Boxes / Total
=3/18
=1/6
So The Answer is 1/6
The experimental probability that the next wooden box will be flawed is 1/6=0.167.
What is experimental probability?
The experimental probability of an event is the ratio of the number of outcomes in which a specified events occurs to the total trials.
Mathematically, Experimental probability= f/n, where f is the number of times an event occurs, n is the total number of trials.
Total number of wooden boxes= 18
Total number of boxes that are flawed= 3
Therefore, required experimental probability = 3/18
=1/6
Hence, the experimental probability that the next wooden box will be flawed= 1/6

What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17 units
Step-by-step explanation:
Going from one point to the other, the change in x is 15 and that in y is 8. Therefore, applying the Pythagorean Theorem,
distance = √(225 + 64) = √289 = 17
The distance between the two points is 17 units.
Answer:
Solution :-Distance = √(x2 - x1)² + √(y2 - y1)²
Distance = √(7 - (-8))² + √(8 - 0)²
Distance = √(7 + 8)² + √(8)²
Distance = √(15)² + √(8)²
Distance = √(225 + 64)
Distance = √(289)
Distance = 17 unit
