Answer:
79
Step-by-step explanation:
60<xy<100
y -2 =x
if it is prime
y cannot be even
so y could be 1,3,5,7,9
x would then be 9,1,3,5,7
but to be between 60 and 100
x must be 7 or 9
so the number must be 79 or 57
57 is not prime so
the number is 79

Step-by-step explanation:
The heights of young American women, in inches, are approximately Normally distributed with mean μ and standard deviation σ = 2.4. If I want to construct a 99% confidence interval with a margin of error of no more than ± 1 inch, what is the smallest sample I can select?
Answer:
y = -1/5x +5
Step-by-step explanation:
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
y = -1/5x +5
Answer:
Yes there is enough information to find both triangles DEF and DHG are congruent.
Both the triangles are congruent by SAS theorem of congruence.
Step-by-step explanation:
Lets have a look to both of the triangles.
And mention what are the given information in our question.
We have
DEF and
DHG.
Where
- FD
DG - ED
DH
And we can see that
(Vertically opposite angles).
So we have two sides equal and an angle between the two are equal.
Then we can say that through SAS property of congruence
DEF and
DHG are congruent
