Answer: FIRST OPTION
Step-by-step explanation:
To solve this problem you must apply the Intersecting Secant-Tangent Theorem. By definition, when a secant line and a tangent lline and a secant segment are drawn to a circle from an exterior point:

The total measure of the secant shown is:

If the radius is 7, then the diameter is:

Therefore:

You also know that:

Keeping the above on mind, you can substitute values and solve for x:

Answer:
a) 0.923
b) 0.957
c) 0.88
d) 0.077
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 40
Standard Deviation, σ = 14
We are given that the distribution of number of milligrams of porphyritic per deciliter of blood is a bell shaped distribution that is a normal distribution.
Formula:
a) P(xis less than 60)
P(x < 60)
Calculation the value from standard normal z table, we have,
b) P(x is greater than 16)
Calculating the value from the standard normal table we have,
c)P(x is between 16 and 60)

d) P(x is more than 60)
P(x > 60) = 1 - P(x < 60) = 1 - 0.923 = 0.077
Answer:
yeah the answer is
bounjour messimie Step-by-step explanation:
Step-by-step explanation:
divided 20 by 5 times that by 4
20 divided by 5 is 4
4x4 is 16 its 16 you got it right
