Answer:
a part of the population that represents the entire population
Step-by-step explanation:
A sample simply refers to a smaller group of observation usually drawn from a larger group or a collection of the total possible observation that fits a particular or specific characteristic(population). This smaller group or subset of observation is usually chosen to be representative of the larger group of population. Representative Samples are usually obtained by drawing at random from the population and are very important where using the entire population for a study seems impossible or very expensive or intensive.

All the three sides are equal. So, it is equilateral triangle.
All the angles are less than 90°, so, it is acute triangle
Answer:
it's acute and equilateral
Step-by-step explanation:
1. is a hanger a/an right,acute, or obtuse triangle?
2. is it a/an equilateral, scalene or isosceles triangle? please put an explanation for both, thanks :)
Answer:
1. acute 2. isosceles
Step-by-step explanation:
1. Acute means less then a 90 degree angle a hanger has a degree of about 60.

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 120 and a standard deviation of 10. Using the empirical rule, determine the interval of systolic blood pressures that represent the middle 99.7% of males.
Answer:
[tex]G=93\ to\ 147[/tex]
Step-by-step explanation:
From the question we are told that
Mean [tex]x= 120[/tex]
Standard deviation [tex]\sigma= 9[/tex]
Percentage for men =99.75%
Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean
Standard deviation n= 9
Mean x= 120
Generally the interval of systolic blood pressure for middle 99.7 of male G is mathematically given as
[tex]G=Mean \pm 3* \sigma[/tex]
[tex]G=120 \pm 3*9[/tex]
[tex]G=93\ to\ 147[/tex]

10. The dimensions of a triangular prism are shown in the diagram. 10 cm 10 cm www 8 cm 34 cm -12 cm What is the volume of the triangular prism in cubic centimeters?
Answer:
I dont understand, what does www mean?
Step-by-step explanation:
Uhm I would appreciate the length and height so I can solve.
Remember formula of a triangle is:
BH x 1/2
OK so 8 x 12 = 96
96 divided by 23 = 32
Your answer is 32 I am pretty sure if that's the following formula of a PRISM. Please wait for more responses if needed, thank you.
Without division:
8 x 12 = 96

Answer:
L=74
W=77
Step-by-step explanation:
Answer:
L=74 and W=77
Step-by-step explanation:
first the area of a rectangle is length of breath
A=L X W
4514= L X 61
61L=4514
L=4514/61
L=74m
b. perimeter =2(L + W)
338=2*92+ 2W
338=184+2W
2W=338-184
2W=154
W=154/2
W=74
what is the slope of the line?
Answer: -2/3
i hope this helps!
Answer:
[tex]\sf -\cfrac{2}{3}[/tex]Step-by-step explanation:
To measure slope, we pick any two points on the line. Then we look at the horizontal and vertical distances between those points.
Going from the point on the left to the point on the right, the change in y is -2 and and the change in x is 3.
[tex]\sf Slope=\cfrac{rise}{run} =\cfrac{-2}{3}[/tex]
[tex]\sf = -\cfrac{2}{3}[/tex]
The slope of the line is -2/3

What is the axis of symmtry
Answer:
The axis of symmetry of a parabola is a line about which the parabola is symmetrical.
Step-by-step explanation:
The axis of symmetry of a parabola is a line about which the parabola is symmetrical. When the parabola is vertical, the line of symmetry is vertical. When a quadratic function is graphed in the coordinate plane, the resulting parabola and corresponding axis of symmetry are vertical.

Ana has a hypothesis that girls get up earlier and, as a result, usually enter Ana's Donut Shop before boys do. To
test her hypothesis, she spends 10 mornings asking the first 3 people to enter her shop whether they are a boy
or a girl.
The data she collects is given in the table below. "G" represents a girl, and "B" represents a boy.
Drag the bars to make a relative frequency plot that shows the proportion for each possible number of girls in
the first 3 customers in a day.

How do you do this I'm so stuck.
Answer:
multiple answers below
Step-by-step explanation:
a = 8.6
b = 4.5
c = 9.71
formula for area :: a = b*h / 2
8.6 * 4.5 = 38.7 / 2 = 19.35
perimeter = a+b+c= 8.6 + 4.5 + 9.71 = 22.81

Gross profit of Inner Spark's company amounted to Php275,000. Net Sales is Php400,000 compute for cost of goods sold?
Answer:Cost of goods sold =Php125,000
Step-by-step explanation:
Profit = Cost Price-Selling Price
Also we know that
Gross Profit = Net Sales– Cost of Goods Sold
Php275,000=Php400,000– Cost of Goods Sold
Cost of Goods Sold=Php400,000-Php275,000=Php125,000

Parallelogram L M N O is shown. Angle N is (5 x) degrees and angle L is (3 x + 40) degrees. In parallelogram LMNO, what is the measure of angle M? 20° 60° 80° 100°
Answer:
80degrees
Step-by-step explanation:
Find the diagram attached
From the diagram, the opposite angle of the parallelogram are equal hence;
5x= 3x+40
5x - 3x = 40
2x = 40
x = 40/2
x = 20degrees
Also <M + <N = 180
<M + 5x = 180
<M + 5(20) = 180
<M + 100 = 180
<M = 180-100
<M = 80degrees
Hence the measure of angle M is 80degrees
Answer:
80

15. What is the rule for an arithmetic sequence whose first term is 12 and the common
difference is 9?
Answer:
T1=12 a=12 a=T1
d=9
your Arithmetic equation is Tn=a+(n-1)d
Tn=a+(n-1)d
SUBSTITUTE a and d in your equation
Tn=12+(n-1)(9)
Tn=12+9n-9
Tn=3+9n or Tn=9n+3

Q4) Identify which of the following are geometric sequences and which are
not
(i) 2, 6, 18, 54.....
(ii) 25,5, 1,
(iii) 1, 4, 9, 16
Answer:
(i) and (ii)
Step-by-step explanation:
For a sequence to be geometric then the ratio r between consecutive terms must be common.
(1)
2, 6, 18, 54
6 ÷ 2 = 3
18 ÷ 6 = 3
54 ÷ 18 = 3
Here there is a common ratio r = 3 , then sequence is geometric
(ii)
25, 5, 1
[tex]\frac{5}{25}[/tex] = [tex]\frac{1}{5}[/tex] and [tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{1}{5}[/tex]
There is a common ratio r = [tex]\frac{1}{5}[/tex] , then sequence is geometric
(iii)
1, 4, 9, 16
4 ÷ 1 = 4
9 ÷ 4 = 2.25
16 ÷ 9 = 1.777..
There is no common ratio, then sequence is not geometric
