Answer:
z = 106°
As a straight line has total 180°
Find the top inside angle:
t + 142° = 180°
t = 180° - 142°
t = 38°
Two opposite angles sum up to exterior angle.
<u>Now find z:</u>
68° + 38°
106°

Answer:
The probability that the product of 2 numbers that Drake rolls is less than = 
Step-by-step explanation:
Drake rolls two fair number cubes i.e. 6 sided die. He then multiplies the numbers shown on each die. The result of the all possible products are shown in the given table. The given table is missing a 1 in the first row. The complete first row will be:
1 2 3 4 5 6
The total number of possible outcomes are 36. We have to find the probability that product of two numbers that Drake rolled is less than 10. For this, first we need to count the number of outcomes that are less than 10. From the table we can see that the number of possible outcomes that are less than 10 are = 17
Probability is defined as the ratio of favorable outcomes to the total number of outcomes. Here, total outcomes are 36 and favorable outcomes are 17.
So,
The probability that the product of 2 numbers that Drake rolls is less than = 
The 99% Confidence interval for the mean sale time for all homes in the neighborhood is:87.857, 112.143.
<h3>Confidence interval</h3>
a. The assumption is: Assume that the population has a normal distribution.
The CI is exact for the normal populations and for small samples the z-interval method should be used in a situation where the variable is normally distributed.
b. Confidence interval:
CI=Sample mean±z-score×Standard deviation/√Size of the sample
CI=100-2.576×20/√18, 100+2.576×20/√18
CI=100-12.143, 100+12.143
CI=87.857, 112.143
Therefore the 99% Confidence interval is 87.857, 112.143.
