Answer:
F(4) = 9
Step-by-step explanation:
Notice that for f(4), we need to use the function definition for the partitioned Domain that includes x = 4, and that is the expression :
Therefore:
Using proportions, it is found that $55.7 billion was donated to educational organizations.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Of the $371 billion donated in total, 15% went to educational organizations, hence the amount is given by:
A = 0.15 x 371 = $55.7 billion.
Hence $55.7 billion was donated to educational organizations.

Answer:
1.8% or 1.818181%
Step-by-step explanation:
If in a batch of 440 water purifiers, we find 8 to be defective.
Then the probability of the next purifier being defective is 8/440
In percentage = 8/440 * 100
=> 8/44 * 10
=> 8/22 * 5
=> 40/22
=> 20 / 11
20/11 is roughly 1.8181818
Rounding it to the nearest tenth, we get 1.8%

Step-by-step explanation:
n = 8
This is the left tailed test .
The null and alternative hypothesis is ,
Test statistic = z=-3.12 from the table.
P(z <-3.12 ) = 0.0009
P-value =0.0009
