Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

Given that n = 49, μ = 260 mg/dL, σ = 35 mg/dL
a) For x < 210:

From the normal distribution table, P(x < 210) = P(z < -10) = 0.0001
b) For x > 205:

For x < 215:

P(205 < x < 215) = P(-11 < z < -9) = P(z < -9) - P(z < -11) = 0.0001 - 0.00001 = 0.00009
c) For x < 200:

From the normal distribution table, P(x < 200) = P(z < -12) = 0.00001
d) For x > 222:

From the normal distribution table, P(x > 200) = 1 - P(z < -12) = 1 - 0.0001 = 0.9999
<u>Given:</u>
The circle has a diameter of 30 cm and a chord of 10 cm is drawn.
Radius of the circle = 15 cm
Half of the chord = 5 cm
We need to determine the distance of chord from the center of the circle.
<u>Distance of chord from the center of the circle:</u>
Let us use the Pythagorean theorem, to find the distance between the center and the chord.
Let d denote the distance between the center and the chord of the circle.
Thus, we get;



Taking square root on both sides, we get;

Thus, the distance between the center and the chord of the circle is 14.14 cm.
Hence, Option A is the correct answer.
Answer:
Janelle should save $13.60 per week
because (350 - 105.20) + 18 13.6
Step-by-step explanation:
105.20-350.00=244.8
244.8/18=13.6
Answer: its x=14
