Answer:
0.945200708
Step-by-step explanation:
In this question, we are asked to calculate the probability that a person selected at random would live less than 65.
To solve this problem, what we need to do is to first calculate the z-score.
Mathematically, z = (x-mean)/standard deviation
According to the question, the mean is 53 years and the standard deviation is 7.5
Substituting these values in the z-score equation:
Z-score = (65-53)/7.5 = 12/7.5 = 1.6
We proceed to use the z-score table to obtain the probability. Using the table, z score of 1.6 corresponds to a probability of
0.945200708
7(x + 2) = 7x + 14...and 7x + 14
there will be infinite solutions because these 2 equations are the same line
Answer:
The image of a translation, reflection, or rotation is congruent to the original figure, and the image of a dilation is similar to the original figure. Two figures are similar when one can be obtained from the other by a sequence of translations, reflections, rotations, and dilations.
Answer:
assuming you want to get rid of the radical here so, 25/2
Step-by-step explanation:
raise the whole fraction to the second power, and the radical will cancel out, then solve 5^2 which is 25. end up with 25 over 2
