Answer:
Quartile 1 is 18
Step-by-step explanation:
Arrange the numbers in order from least to greatest;
18, 18, 18, 20, 21, 22, 23, 23, 24, 24
Find the Median = (21+22)/2= 21.5
Find the median (Q1) between 21.5 and 18 = 18
Find the median (Q2) between 21.5 and 24 = 23
Answer: 11x^2+48x
---------------------------------------
Work Shown:
(x^2+43x+10) - (-10x^2-5x+10)
x^2+43x+10 - (-10x^2) -(-5x) -(10)
x^2+43x+10 + 10x^2+5x-10
(x^2+10x^2)+(43x+5x)+(10-10)
11x^2+48x+0
11x^2+48x
Answer:
k = 2
x = 2y
Step-by-step explanation:
If variables x and y vary directly, this is expressed as;
x ∝ y
x = ky
k is the proportionality constant
Let's assume the value of x and y since we are not given;
x = 20
y = 10
Substitute
20 = k(10)
10k = 20
k = 20/10
k = 2
Hence the constant of proportionality is 2
Substitute i=k = 2 into the equation x = ky
x = 2y
Hence an equation that relates x and y is x = 2y
<em>Note that the values here are assumed value, you can use the same method for any values of x and y</em>
Am sure it’s the 1 first option
I√49=7i
They are equal btw
