Answer:
Variation equation: y = k/√x
constant of variation: 200
Variation Equation by plugging the value of k: y = 200/√x
Step-by-step explanation:
If y varies inversely with the SQUARE ROOT of x, then;
y = k/√x
If x = 4, y = 100.
100 = k/√4
100 = k/2
200 = k
k = 200
Substitute into the expression
y = k/√x
y = 200/√x
To find the interquartile range, you will list the data that is presented in the stem and leaf plot.
Find the median of the data (30.5)
Find the median of the lower half and the median of the upper half.
Subtract these two values.
The data are <u>20</u>, 25, 30, 30, 31, 40, 41, <u>49</u>.
27.5 40.5
40.5-27.5 = 13
The interquartile range is 13.
4/3
explanation : just write it in fraction form
<h3>
Answer:</h3><h3>x=−8</h3><h3 />
Step-by-step explanation:
<h3>Let's solve your equation step-by-step.</h3>
−3x+10=34
<h3>Step 1: Subtract 10 from both sides.</h3>
−3x+10−10=34−10
−3x=24
<h3>Step 2: Divide both sides by -3.</h3><h3 />
−3x/−3 = 24/−3
<h3>x=−8</h3>
