Serena has 6 photo albums with 15 photos in each
so serena has (6 * 15) = 90 photos.
maya has 8 albums with 13 photos in each.
so maya has (8 * 13) = 104 photos
if serena add another 12 photos to her album....(90 + 12) = 102 photos
so in total, serena and maya have 102 + 104 = 206 photos <=
Answer:
The solution to the system is all the points that satisfy both inequalities or the region in which the shading overlaps. Given the system of linear inequalities shown in the graph, let's determine which points are solutions to the system. The point (0, -1) is not a solution to the system of linear inequalities.

Answer:
96.4% of people have an IQ score between 69 and 132
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
What percentage of people have an IQ score between 69 and 132, to the nearest tenth?
The proportion is the pvalue of Z when X = 142 subtracted by the pvalue of Z when X = 69. The percentage is the proportion multiplied by 100. So
X = 132
has a pvalue of 0.983
X = 69
has a pvalue of 0.019
0.983 - 0.019 = 0.964
0.964*100 = 96.4%
96.4% of people have an IQ score between 69 and 132
First, you know that c and d add up to the same degree so you can solve that bottom triangle. A triangle adds up to 180 degrees and 40+40-180 is 100 which is our missing angle. The two other connecting sides are also equivalent to this new angle(100) which helps you solve the triangle to the right. You take the given angle of A(40) which is equivalent to b and add 100. After you would subtract the sum of the triangle which is 40. For your final answer you would take this new angle and add it to angle d to get your answer 80.
