A histogram is used to show the frequency of data, where the length of the bar represents the frequency.
<em>From the histogram, 50 students drank the recommended amount of water.
</em>
Given that
or more
The number of students who drank the recommended amount are students whose frequency is at least 48
From the attached histogram, only 1 bar has a frequency that is at least 48 or more
And the number of students in this bar is: 50
Hence, 50 students drank the recommended amount of water,

Answer:
Pippa
Step-by-step explanation:
A square has
- parallel opposite sides
- perpendicular adjacent sides
- perpendicular diagonals
A rhombus has
- parallel opposite sides
- non-perpendicular adjacent sides
- perpendicular diagonals
Thus, we can identify the shape by comparing the slopes of the adjacent sides.
1. Draw the shape
See the graph below
2. Calculate the slope of AB
m = (y₂ - y₁)/(x₂ - x₁) = (4 - (-1))/(9 - 5) = (4 + 1)/4 = 5/4
3. Calculate the slope of BC
If BC⟂AP, its slope should be -4/5
.
m = (y₂ - y₁)/(x₂ - x₁) = (1 - 4)/(15 - 9) =-3/6 = -1/2
½ ≠ -⅘
The two lines are not perpendicular.
Pippa is right. The shape is a rhombus.
Step-by-step explanation:
Mid point formula ,
x = (x1+x2)/2 , y = (y1+y2)/2
x = 1 , y = 4
therefore ,midpoint is (x, y)= (1,4)

Step-by-step explanation:
Answer:
c) g(x) = - √x + 3
Step-by-step explanation:
f(x) = √x
Reflected x-axis: g(x) = - √x
Then shift upward 3 units: g(x) = - √x + 3
Answer: g(x) = - √x + 3
