Answer:18/4= 9/2
24/32= 3/4
Step-by-step explanation:
for 18/4 divide both numbers by 2
= 9/2
for 24/32 divide both numbers by 8
=3/4
Let's actually find the roots, using the quadratic formula:
<span>p(x)=x^2+x+3 gives us a=1, b=1 and c=3.
-1 plus or minus sqrt(1^2-4(1)(3))
Then x = -----------------------------------------------
2
The discriminant here is negative, so the roots x will be complex:
-1 plus or minus sqrt(-11) -1 plus or minus i*sqrt(11)
x = ---------------------------------- = -------------------------------------
2 2
These are irrational roots; they cannot be expressed as the ratios of integers.</span>
Answer:
Option 3
Step-by-step explanation:
The number on the inside is the dividend and the number on the outside is the divisor. So we just have to place the dividend on the top and the divisor on the bottom.
Answer:
Jaime's. Interval not centered around the point estimate.
Step-by-step explanation:
When constructing a confidence interval based on a point estimate, the obtained point estimate must be the central value of the interval.
For Jaime's interval
Lower bound = 0.078
Upper Bound = 0.193
For Mariya's interval
Lower bound = 0.051
Upper Bound = 0.189
For a point estimate of 0.12, only Mariya's interval is adequate since Jaime's is not centered around the point estimate.
