Answer:
The approximate percentage of women with platelet counts within 3 standard deviations of the mean is 99.7%.
Step-by-step explanation:
We are given that the blood platelet counts of a group of women have a bell-shaped distribution with a mean of 247.3 and a standard deviation of 60.7.
Let X = <em>t</em><u><em>he blood platelet counts of a group of women</em></u>
The z-score probability distribution for the normal distribution is given by;
Z = ~ N(0,1)
where, = population mean = 247.3
= standard deviation = 60.7
Now, according to the empirical rule;
- 68% of the data values lie within one standard deviation of the mean.
- 95% of the data values lie within two standard deviations of the mean.
- 99.7% of the data values lie within three standard deviations of the mean.
Since it is stated that we have to calculate the approximate percentage of women with platelet counts within 3 standard deviations of the mean, or between 65.2 and 429.4, i.e;
z-score for 65.2 =
= = -3
z-score for 429.4 =
= = 3
So, it means that the approximate percentage of women with platelet counts within 3 standard deviations of the mean is 99.7%.

Step-by-step explanation:
The longest side is opposite the largest angle, and the shortest is opposite the smallest one.
The largest angle lies opposite the longest side, and the smallest is opposite the smallest side.
Q1.
Calculate m∠Y.
We know: Measures of angles of triangle add up to 180°.
m∠Y + m∠W + m∠X = 180°
Substitute given angles:
m∠Y + 51° + 90° = 180°
m∠Y + 141° = 180° <em>substitute 141° from both sides</em>
m∠Y = 39°
39° < 51° < 90° → XW < XY < YW
