Answer:
Step-by-step explanation:
What percent of values is between the first and third quartiles
50 < 75 < 87.5 < 100 < 125 < 150 < 175 < 200 < 212.5 < 225 < 250
Then we have 5 values between the first and third quartiles which are :
100, 125, 150, 175, 200
Therefore,
The percent of values between the first and third quartiles is :
Answer: x=3.6; y=-2.5
Step-by-step explanation:
To solve this pair of equations, we can use elimination method.
5x+4y=8
10x-4y=46
Add both equations together to cancel out 4y.
15x=54 [divide both sides by 15]
x=3.6
Now that we know x, we can plug it back into any equation to find y.
5(3.6)+4y=8 [multiply]
18+4y=8 [subtract both sides by 18]
4y=-10 [divide both sides by 4]
y=-2.5
Now, we have x=3.6 and y=-2.5.
Answer:
angle B=92
Step-by-step explanation:
cos C= adj/hyp
sin C=12/14=6/7 ( in rad.)
angle C is 31 degree
the sum of angles of triangle =180
angles A+B+C=180
angle B=180-(31+57)=92 degrees
Answer:
The answer is Junichi's garden is wider than 50 ft.
Step-by-step explanation:
The inequality means that x is greater than the value of 50. It also does not have a line under the symbol, so it doesn't mean greater than or equal to. Due to this, any answer where the value is equal to or less than the value of 50 is incorrect.
Answer:
y-4=-7(x-3) and y=-3/8x-8
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)
the slope is already -7.
We can the just plug in the values: y-4=-7(x-3)
For the 2nd problem we can plug in values as well: -2=3/8(16)+b.
-2=6+b. the y intercept is -8. The final form is y=-3/8x-8
