The answer is -27
hope u're ok with that.......
For triangles, the formula to find area is base*height/2. So just plug the numbers in to get 11.5*6.7/2=38.525 meters squared.
For a rhombus, the area formula is just base*height, resulting in 4.75*9.2=43.7 meters squared
Answer:
(D) 99.7%
Step-by-step explanation:
We are asked to find the percentage of 18-year-old women that will have a systolic blood pressure that lies within 3 standard deviations of the mean.
The empirical rule of normal distribution states approximately 68% of data lies within one standard deviation of mean, approximately 95% of data lies within two standard deviations of mean and approximately 99.7% of data lies within three standard deviations of mean.
Since the systolic blood pressure of 18-year-old women is normally distributed, therefore, 99.7% of 18-year-old women have a systolic blood pressure that lies within 3 standard deviations of the mean.
Step-by-step explanation:
We know that the length of the diagonals will be more than the side.
Lets suppose the quadrilateral is a rectangle, with sides 6 and 4.
The length of a diagonal is:
√(6*6)+(4*4)
√36+16
√52
7.21(rounded off to 3 sig. fig.)
So, 6+4+6+4<2(7.21+7.21)
20< 2*14.42
20<28.84, which is true.
