Explanation:
A town has two shopping malls. A survey conducted on the shopping preferences of the town's residents showed that 62% of the residents visit Comet Mall, 73% of the residents visit Star Mall, and 48% of the residents visit both malls.
The probability that a resident chosen at random shops at either Comet Mall or at Star Mall is
%.?
PLZ help what is the percent??
Given:
62% of the residents visit Comet Mall.
73% of the residents visit Star Mall.
48% of the residents visit both malls.
To find:
The probability that a resident chosen at random shops at either Comet Mall or at Star Mall.
Solution:
Let A be the event that the residents visit Comet Mall and B be the event that residents visit Star Mall. Then, we have
[tex]P(A)=62\%[/tex]
[tex]P(B)=73\%[/tex]
[tex]P(A\cap B)=48\%[/tex]
We need to find the probability that a resident chosen at random shops at either Comet Mall or at Star Mall. It means, we have to find the value of [tex]P(A\cup B)[/tex].
We know that,
[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
On substituting the given values, we get
[tex]P(A\cup B)=62\%+73\%-48\%[/tex]
[tex]P(A\cup B)=87\%[/tex]
Therefore, the probability that a resident chosen at random shops at either Comet Mall or at Star Mall is 87%.

Explanation:
A camper takes a 100-gram piece of basalt rock from a campfire and places it in a cup holding 250 mililiters of water. The temperature of the rock is 300C and the temperature of the water is 20C. Air temperature is also 20C. In the process of heating the water with the basalt, the temperature of the basalt decreased more than the temperature of the water increased. This difference most likey occured because
Answer:
This difference most likely occurred because the specific heat of water is higher than that of basalt.
Explanation:
Basalt is a fine-grained, dark-colored igneous rock that is mostly made up of plagioclase and pyroxene minerals.
Water is a gaseous, liquid, or solid substance made up of the chemical elements hydrogen and oxygen, and it can exist in gaseous, liquid, and solid states.
Basalt can be used to heat water. But when the specific heat of water is higher than that of basalt, the temperature of the basalt will drop more than the temperature of the water will rise when the water is heated with the basalt.
Therefore, this difference most likely occurred because the specific heat of water is higher than that of basalt.

should wave energy be developed? give your reasons
Answer:
Wave energy is unique because it is the most concentrated form of renewable energy on earth, with power density much higher than that of wind and solar energy. ... As waves can travel for hundreds and even thousands of kilometers with virtually no loss of energy, they act as an energy reservoir charged by the wind.

What form of deductive reasoning is used in the given argument? If a number ends in 0, then it is divisible by 10. If a number is divisible by 10, then it is divisible by 5. If a number ends in 0, then it is divisible by 5. A. Law of detachment B. Law of syllogism C. Law of contrapositive D. Identification of counterexample
Answer:
B. Law of syllogism.
Explanation:
The deductive reasoning behind the set of arguments is the Law of Syllogism, defined by the following logical rule:
1) [tex]\alpha \Rightarrow \beta[/tex]
2) [tex]\beta \Rightarrow \gamma[/tex]
Hence,
3) [tex]\alpha \Rightarrow \gamma[/tex]
In this case, we have three simple propositions:
[tex]\alpha =[/tex] A number ends in 0.
[tex]\beta =[/tex] A number is divisible by 10.
[tex]\gamma =[/tex] A number is divisible by 5.
The reasoning represented by the consecutive arguments is:
1) If a number ends in 0, then it is divisible by 10.
2) If a number is divisible by 10, then it is divisible by 5.
Hence,
3) If a number ends in 0, then it is divisible by 5.
