Concept explainers

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

100%

Make sure your answer is correct.

Suppose there are two manufacturers A and B of a smartphone battery Company A manufactures the
fraction of 60% of all the batternes used in the smartphones while company B manufactures the rest
Assume that the hfetime of each battery is a continuous random variable T (with parameter A > 0)
whose probabılıty density function is given by
「景 (1-) for 0 S“n>
fa(t) =
%3D
0.
otherwise
The parameter A depends on the manufacturer of the battery If the battery s manufactured by A then
A =1 while if it is manufactured by B then A = 2 Suppose you buy a new smartphone that is randomly
picked among all the produced phones Compute the expectation and variance of the lifetime of the battery
of your new phone
Hınt In calculatıng the expectation and variance you should condition on the manufacturer of the battery

Find x
Please share the solution for the last 2 parts (c & d) in bold. The first three parts answered by your team. In a study of the Gouldian finch, Griffith et al. (2011) looked at stress caused by having an incompatible mate.There are two genetically distinct types of Gouldian finches, one having a red face and the other having a black face. Previous experiments have shown that female finches have a strong preference for mating with males with the same face color as themselves , and that when different face types of finch mate with one another, their offspring are less likely to survive than when both parents are the same type. Researchers paired females sequentially with males of both types in random order,In other words, each female bred twice once with a compatible male and once with an incompatible male.Each time, females produced a brood of young with the assigned male.For each pairing, the researchers measured the blood corticosterone concentration (in units of ng/ml) as an index…
