Answer:
option 1) 50
Step-by-step explanation:
Let m and w denote the men and women respectively.
From the question, if the groom invited w number of women, then bride invited 2w number of women.
Also, if the bride invited m number of men,then the groom invited 2m.
Hence we can write the following maths equation:
w+2m=105.........1
2w+m=135.........2
We multiply eqn(1) by 2 to get eqn(3)
This implies that,
2w+4m=210.......3
We then subtract eqn (2) from eqn(3) to obtain;
3m=75
we divide through by 3
Substituting the value of m into eqn (1)
to find the value for w
subtracting 50 from both sides.
So we can say the :
bride invited 25 men and 110 women,
groom invited 50 men and 55 women.
Answer:
slope is (-7/4) and y-intercept is 7
Step-by-step explanation:
If we convert the equation 7x + 4y = 28 into Slope-intercept form, we can find the slope and the y-intercept.
7x + 4y - 7x = 28 - 7x
4y = 28 - 7x
divide both sides by 4
y = (28 - 7x)/4
y = 7 - 7x/4
slope is (-7/4) and y-intercept is 7
Any line can be expresses as:
y=mx+b where m=slope=(y2-y1)/(x2-x1) and b=y-intercept (value of y when x=0)
First find the slope:
m=(2-0)/(8-0)=2/8=1/4 so we have thus far:
y=0.25x+b, we solve for b using any point on the line, (8,2)
2=0.25(8)+b
2=2+b
0=b
So the line is:
y=.25x which they might also express as y=x/4
The answer is E. (1/4)x
Answer:
And replacing we got:
And we can calculate this probabilit using the normal standard distribution or excel and we got:
Step-by-step explanation:
If we define the random variable of interest "the amount spent by a family of four of food per month" and we know the following parameter:
And we want to find the following probability:
And we can use the z score formula given by:
And replacing we got:
And we can calculate this probabilit using the normal standard distribution or excel and we got:
