Answer:
B?
Step-by-step explanation:
true because the square root is a number times itself and 4*4 is 16
Answer:
Probability that average height would be shorter than 63 inches = 0.30854 .
Step-by-step explanation:
We are given that the average height of 20-year-old American women is normally distributed with a mean of 64 inches and standard deviation of 4 inches.
Also, a random sample of 4 women from this population is taken and their average height is computed.
Let X bar = Average height
The z score probability distribution for average height is given by;
Z =
~ N(0,1)
where,
= population mean = 64 inches
= standard deviation = 4 inches
n = sample of women = 4
So, Probability that average height would be shorter than 63 inches is given by = P(X bar < 63 inches)
P(X bar < 63) = P(
<
) = P(Z < -0.5) = 1 - P(Z <= 0.5)
= 1 - 0.69146 = 0.30854
Hence, it is 30.85% likely that average height would be shorter than 63 inches.
Answer:
6:5
Step-by-step explanation:
divide both numbers by using gcd/ greatest common divisor
= 12:10/ 2
=6:5

Answer:
<em>Yes, but only if BC ≅ DC; Option B</em>
Step-by-step explanation:
There are 4 possible ways to determine whether two triangles are congruent, and they are the following ;
ASA ( Angle - Side - Angle ),
SAS ( Side - Angle - Side ),
AAS ( Angle - Angle - Side ), and
SSS ( Side - Side - Side )
It is known here that we must prove these triangles congruence through SSS. A triangle can thus be made possible through the congruence of corresponding sides;
Now if we were to create these triangles it would be that BC and DC are, if the triangles were to coincide with one another, the apparent same length if it were that these two Δs really are ≅. Thus;
<em>Solution; Yes, but only if BC ≅ DC</em>
