Answer:
a) "engaged" is a quantitative and continuous variable.
b) The sample proportion of students in this high school district who are engaged is 0.4222
Step-by-step explanation:
Given the data in the question;
Polling reports shows that 0.34 12th grade students are engaged
the principal surveyed 90 of the 3600 students,
number of students reported to be engaged is 38
a)
"engaged" is a quantitative and continuous variable.
b) the sample proportion of students in this high school district who are engaged.
Sample proportion of engaged = number of students reported to be engaged / total number of students surveyed
so
Sample proportion of engaged = 38 / 90
Sample proportion of engaged = 0.4222
Therefore, the sample proportion of students in this high school district who are engaged is 0.4222

Inscribed Angles B
Find each measure.
K
X=
6x
M
L
Answer:
x = 15
z = 25
Step-by-step explanation:
In [tex] \odot\: O, \: \angle MLK [/tex] is inscribed in a semicircle.
[tex] \therefore m\angle MLK =90\degree [/tex]
[tex] \therefore 6x\degree =90\degree [/tex]
[tex] \therefore 6x =90[/tex]
[tex] \therefore x =\frac{90}{6}[/tex]
[tex] \therefore x =15[/tex]
In [tex] \odot\: A, \: \angle PRQ[/tex] is inscribed in a semicircle.
[tex] \therefore m\angle PRQ =90\degree [/tex]
[tex] \therefore (4z-10)\degree =90\degree [/tex]
[tex] \therefore 4z-10 =90[/tex]
[tex] \therefore 4z =100[/tex]
[tex] \therefore z =\frac{100}{4}[/tex]
[tex] \therefore z =25[/tex]

Hi his figure is made up of unit cubes, each with a volume of 1 cubic unit.
What is the volume of the figure?
( photo is attached)
(Will give brainliest if you help)
Answer:
D. 100 cubic units
Step-by-step explanation:
There are 10 cubes in each layer (count at the top) and 10 layers (from top to bottom) in total. Multiply these to get volume.
10 x 10 =100
Answer:
B. 60 cubic units
Step-by-step explanation:
Formulas for a cube:
The volume of a cube:
V = a3
The surface area of a cube:
the area of each face (a x a) times 6 faces
S = 6a2
Face diagonal of a cube:
By the Pythagorean theorem, we know that
f2 = a2 + a2
Then f2 = 2a2
solving for f we get
f = a√2
Diagonal of the solid cube:
Again, by the Pythagorean theorem, we know that
d2 = a2 + f2
substituting f into this equation we get
d2 = a2 + (a√2)2 = a2 + 2a2 = 3a2
solving for d we get
d = a√3

The average weekly salary of two employees is $5250. One makes $500 more than the other. Find their salaries.
Answer: thier salaries are $5000 and $5500
Step-by-step explanation:
Let the average weekly salary of one employee be =x
And that of the other employee be = x+500
Such that if thier average of their salaries= $5250
So, their total salary= $5250 x 2=10,500
The equation to solve each employee salary becomes
x+x+500=10,500
2x+500=10,500
2x=10,500-500
2x=10,000
x=10,000 /2
x= first employee salary =$5000
second employee = x+500 =$5500

A local cable TV/Internet/phone provider charges new customers $129 for all three services, per month, for the first year under their "3 for 129" promotion. Joanne normally
pays $74 for her monthly home phone service, $59 for Internet service, and $69 for cable television
a. What are her percent savings if she switches to the "3 for 1299 plan? Round to the nearest percent.
b. If, after the first year, the flat fee for all three services is $139, what are her percent savings? Round to the nearest percent.
Answer:
Step-by-step explanation:
Amount paid by Joanne before promotion = 74 + 59 + 69 = $ 202
a) Amount saved if she switches to "3 for 129 plan" = 202 - 129 = $ 73
Percentage of saving = [tex]\frac{73}{202}*100[/tex] = 36.13 = 36%
b) Amount saved after the first year = 202 - 139 = $ 63
Percentage of saving = [tex]\frac{63}{202}*100[/tex] = 31.18 = 31%

You have 2 shapes, a rectangle and a half circle.
Area of rectangle = 3 x 8 = 24
Area of a half circle = 1/2 x pi x r^2
Area of half circle = 1/2 x 3.14 x 4^2
Area of half circle = 25.12
Total area = 24 + 25.12 = 49.12 square units
Answer:
You have 2 shapes, a rectangle and a half circle.
Area of rectangle = 3 x 8 = 24

Area of half circle = 25.12
