Answer:
And we can find this probability using the complement rule and the normal standard table:
And the best solution would be:
c. 0.3085
Step-by-step explanation:
For this case we can convert all the values to inches in order to standardize the solution:
Let X the random variable that represent the heights of US mens, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
We can use the z score formula given by:
Using this formula we got:
And we can find this probability using the complement rule and the normal standard table:
And the best solution would be:
c. 0.3085
Answer:
y = 5 and x = -3
Step-by-step explanation:
Given,
y = x + 8 ...............( equation 1 )
x + y = 2 ...............( equation 2 )
Now, by substituting the value of y in equation 2, we get;
⇒ x + x + 8 = 2
⇒ x = -3
and now, by substituting the value of x in equation 1, we get;
⇒ y = -3 + 8
⇒ y = 5
Answer: the answer is A
Step-by-step explanation:
If you want 3/4 in 64's, multiply the numerator (3) by 16, as 4 x 16 = 64.
<span>3 x 16 </span>
<span>--------- </span>
<span>4 x 16 </span>
<span>= 48/64</span>
First angle 90 degrees
Second angle 30 degrees
Third angle 60 degrees
