Answer:the mean is the best measure of central tendency for the science class
Step-by-step explanation:
The mean age of 12 women in an office is 26 years old.
The mean age of 4 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office
Answer:
27
Step-by-step explanation:
Well, if the mean of 12 people is 26, you can imagine those 12 people are 26, so 26*12=312. Next, you do the same for the 4 men, so 29*4=116. Then you add those 2 numbers together, to get the total of 428. Divide that by the total amount of people in the office which is 428/16=26.75. Rounding up (because the decimal starts with a number above 5) you get that the average age is 27.
Someone please help me
I don’t understand
I will give brainiest answer
Answer:
Just draw a straight line that intersects or is close with most of the points, in this case the line would be going down meaning it's a negative data point. Now just follow the line and see where it will be when y=2billion. Remember this is not a exact answer your just seeing where most of the points are and predicting based on that.
Find the slope of the line that passes through (5,9) and (3,9)
Answer:
Since the Y coordinate is constantly 9, it is a horizontal line.
Step-by-step explanation:
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 9) and (x₂, y₂ ) = (3, 9)
m = [tex]\frac{9-9}{3-5}[/tex] = [tex]\frac{0}{-2}[/tex] = 0
Irfan incorrectly determined that the equation for the line on the graph is y = 0.5x +5. What is the correct equation for the line?
Answer:
y=-1x+0.5
Step-by-step explanation:
First calculate the slope of the line=y2-y1/x2-x1
Take any two points
1-3/2-1
-2/1
slope=-1
y=mx+c (equation for line)
Take any point and figure the value of c
1=-1x2+c
1/-2=c
c=0.5
y=-1x+0.5
Ali bought a music system for rs 6375.00 and spent rs 75.00 on transportation . He sold it for 6400.00 . Find his profit or loss percent
Answer: Loss percent = 0.775%
Step-by-step explanation:
Here,
Total cost = Purchasing price + transportation
⇒ Total cost = 6375 + 75
⇒ Total cost = $ 6450
Selling price = $ 6400
Total cost > Selling price, hence it is a loss.
Loss percent formula :
[tex]Loss\% =\dfrac{\text{Loss}}{Total\ cost}\times100\\\\=\dfrac{Total\ cost - Selling price}{Total \ cost}\times100\\\\=\dfrac{6450-6400}{6450}\times100\\\\=\dfrac{50}{6450}\times100=0.775\%[/tex]
Hence, Loss percent = 0.775%

The equation tan(55 degree) equals StartFraction 15 Over b EndFraction can be used to find the length of Line segment A C.
Given:
The equation is
[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]
To find:
The length of the line segment AC.
Solution:
We have,
[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]
[tex]1.428148=\dfrac{15}{b}[/tex]
Multiply both sides by b.
[tex]1.428148b=15[/tex]
Divide both sides by 1.428148.
[tex]b=\dfrac{15}{1.428148}[/tex]
[tex]b=10.50311[/tex]
[tex]b\approx 10.503[/tex]
In a triangle ABC, the line of line segment AC is b. So,
[tex]AC\approx 10.503[/tex]
Therefore, the length of the line segment AC is 10.503 units.

7.14
0.14
0.14
1.4
1.4
750
Answer:
0.14
Step-by-step explanation:
To get this, you need to divide the number by a 100.
14/100 = 0.14
Therefore 14% is 0.14 as a decimal.
Hope that helped! :)

please ANSWER at least ONE question CORRECTLY FOR 8 POINTS & ANSWER at least THREE CORRECTLY to be MARKED BRAINLIEST! (you don’t have to do all of them, but it would be greatly appreciated if you did.)
Answer:
a. yes
b. no
c. no
d. no
e. yes
Step-by-step explanation:
Here, we want to answer yes or no for each of the numbers
a) Yes
If we compare with the general form
y = mx + b
m
is slope and b is y-intercept
so, 2 is slope and 3 is y intercept; so 3 in y-intercept is (0,3)
b. No
This is the point-slope form we are trying to
get
Evaluating this, we have that
y-3 = 2x - 6
y = 2x-6 + 3
y = 2x-3
c) NO
Just insert the values and check here
-1 = 2(5) + 3
it does not work
d) No
Substitute
-4 = 2(-5) + 3
e) Yes
This is the point-slope form
y + 3 = 2x + 6
y = 2x + 6-3 = 2x + 3
-5x2(2) + (-2)(2) what is the answer

Write the equation that passes through the point (-2,4) and has a slope of 7
Answer: See explanation
Step-by-step explanation:
Point slope formula = y - y₁ = m (x - x₁)
y - 4 = 7 (x + 2)
y - 4 = 7x + 14
Add 4 to both sides
y = 7x + 18
↑This is also the slope intercept form (y = mx + b)

The number of lawns l that a volunteer can mow in a day varies inversely with the number of shrubs s that need to be pruned that day. If the volunteer can prune 6 shrubs and mow 8 lawns in one day, then how many lawns can be mowed if there are only 3 shrubs to be pruned?
Answer: 16 lawns can be mowed if there are only 3 shrubs to be pruned.
Step-by-step explanation:
Equation of inverse variation: [tex]x_1y_1=x_2y_2[/tex]
Given: Number of lawns l that a volunteer can mow in a day varies inversely with the number of shrubs s that need to be pruned that day.
Then, [tex]l_1s_1=l_2s_2[/tex]
Put [tex]l_1=8,\ s_1=6,\ s_2=3[/tex] [To find: [tex]l_2[/tex]]
[tex]8\times6=3l_2\\\\\Rightarrow\ l_2=8\times2=16[/tex]
Hence, 16 lawns can be mowed if there are only 3 shrubs to be pruned.

Find the value of x in the isosceles triangle shown below.
please help owo
Answer:
10
Step-by-step explanation:
We will first take a right triangle and we will apply the pythagorean theorem to it. First, the base of the right triangle will be 12/2 which is 6; then, we will just use the theorem.
a^2+b^2 = c^2 (pythagorean theorem)
8^2+6^2 = c^2
100 = c^2
c = 10 because the square root of 100 is 10

U2+17u+72. Answer please
Answer:
I believe it's 19u+72
Step-by-step explanation:
Hope this helps! ^^
Answer:
(u + 8)(u + 9)
Step-by-step explanation:
Assuming you require to factorise the expression
u² + 17u + 72
Consider the factors of the constant term (+ 72) which sum to give the coefficient of the u- term (+ 17)
The factors are + 8 and + 9, since
8 × 9 = 72 and 8 + 9 = 17, then
u² + 17u + 72 = (u + 8)(u + 9) ← in factored form
