in a class of 32 students the mean height of the 14 boys is 1.56 meters and the mean height of all 32 students is 1.151 meters. work out the mean height of girls
Answer: Hence, Mean height of the girls is: 1.48
Step-by-step explanation: It is given that:
in a class of 32 students .
the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.
Since there are 14 boys in a class.
So, number of girls is equal to (32-14)=18.
The mean height of 14 boys is 1.56.
Hence the sum of height of 14 boys is= 1.56×14=21.84
Similarly mean height of 32 students is 1.515.
Hence, sum of height of 32 students=1.515×32=48.48.
Let x denote the mean height of 18 girls.
Hence, sum of height of 18 girls is: 18 x.
Now,
18x+21.84=48.48
( since sum of height of girls and boys is equal to the sum of height of all the students)
so, 18x=48.48-21.84
18 x=26.64
Hence, x=1.48
Hence, Mean height of the girls is: 1.48
Please help me with this question, I need to know what X equals
Answer: 11
Step-by-step explanation: m<2 is equal to 42. This also means that 3x+9 is equal to 42.
3x+9=42, solve for x. Subtract 9 from both sides. 3x=33, divide by three to get X isolated. X= 11

Find a coordinates of the midpoint of the line segment with the given endpoints (7,4), (9,-1)
Answer:
Coordinates of midpoint are (8,1.5).
Step-by-step explanation:
Given coordinates of end points are;
(7,4) and (9,-1)
we can find the coordinates of mid-point,
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Here,
x1 = 7 and y1 = 4
x2 = 9 and y2 = -1
Putting these values in formula
Coordinates of mid point = [tex](\frac{7+9}{2},\frac{4+(-1)}{2})\\[/tex]
Midpoint = [tex](\frac{16}{2},\frac{4-1}{2})[/tex]
Midpoint = [tex](\frac{16}{2},\frac{3}{2})[/tex]
Midpoint = 8 , 1.5
Hence,
Coordinates of midpoint are (8,1.5).

planes X and Y are perpendicular. Points A,E,F and G are points only in plane X. Points R and S are points in both planes X and Y. Lines EA and FG are parallel.
Based on this information, which pair of lines, together, could be perpendicular to RS? Select two options.
EA
ER
EF
FG
FS
Answer:
FG
Step-by-step explanation:
I did this on my computer
The pair of the line together, could be perpendicular to RS should be considered as the EA and FG.
What is perpendicular?In terms of elementary geometry, two geometric objects should be considered as the perpendicular when they intersect at a right angle. A line is treated to be perpendicular to another line in the case when the two lines intersect at a right angle.
Therefore, The pair of the line together, could be perpendicular to RS should be considered as the EA and FG.

help me! also show work so i won’t ask again
Answer:
x = 3Step-by-step explanation:
Based on similar triangle;
14/49 = x+5/9x+1
Cross multiply
49(x+5) = 14(9x+1)
49x + 245 = 126x + 14
49x - 126x = 14 - 245
-77x = -231
x = -231/-77
x = 3
Hence the value of x is 3
If annie has 8 apples and eren has 927 ore apples then annie, how much apples does eren have?
Answer:

During crawfish season, Xavier sells crawfish for $62.50 per sack and charges a $20.00 delivery fee. Which equation best represents y, the total cost of x sacks of crawfish delivered to a customer?
A y = (62.50 + 20)x
B y = 62.50 + 20x
C y + 20 = 62.50x
D y = 62.50x + 20
Answer:
d
Step-by-step explanation:
The equation that best represents y, the total cost of x sacks of crawfish
delivered to a customer is y = 62.50x + 20
y = total cost of x sacks of crayfish
x = number of sacks of crayfish
Therefore,
delivery fee = $20.00
The delivery fee is just like a constant in the equation.
amount sold per sack = $62.50
The amount sold per sack is like the slope in the equation.
Therefore,
y = 62.50x + 20
