Answer:
(b) 5 2/5
Step-by-step explanation:
You can figure this one by estimating. The denominator on the right is a little more than double the numerator. Then the denominator on the left (x) will be a little more than double the numerator. Double is 2(2 1/4) = 4 1/2.
The closest reasonable value is 5 2/5.

If you want to work this out in detail, you will see that ...
x = (2 1/4(3 3/5)/(1 1/2)
x = (9/4)(18/5)(2/3) = (9·18·2)/(4·5·3) = 3·18/10 = 5.4 = 5 2/5
Answer:
Stamp collected in June = 33
Step-by-step explanation:
Total stamp = 94
Stamp collected in April = 27
Stamp collected in May = 34
Stamp collected in June = x
Total stamp = April stamp + May stamp + June stamp
94 = 27 + 34 + x
94 = 61 + x
x = 94 - 61
x = 33
Stamp collected in June = 33
Answer:
no because the box needs to be at least 35 inches long and the box the mother found is only 32 inches long.
Answer: x=−9/4
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(x+14)+1=5
Step 1: Simplify both sides of the equation.
−2(x+14)+1=5(−2)(x)+(−2)(14)+1=5(Distribute)−2x+

Answer:
The sum of the squared residuals
Step-by-step explanation:
If you sum the residuals, you would get 0
if you sum of the absolute values of the residuals you wouldn't be doing "least-squares regression"
The influence of outliers D The slope is another metric that has nothing to do in creating the regression line
