Answer:
[tex]Pr(Cat\ and \ Dog) = 0.50[/tex]
Step-by-step explanation:
Given
[tex]Total = 300[/tex]
[tex]Cat\ and\ Dog = 150[/tex]
See attachment
Required
[tex]Pr(Cat\ and \ Dog)[/tex]
This is calculated as:
[tex]Pr(Cat\ and \ Dog) = \frac{n(Cat\ and \ Dog)}{Total}[/tex]
This gives
[tex]Pr(Cat\ and \ Dog) = \frac{150}{300}[/tex]
[tex]Pr(Cat\ and \ Dog) = 0.50[/tex]
Caitlyn recorded the height of each plant after she exposed each plant to a set amount of darkness daily. The scatterplot shows her results after 2 weeks of exposing each plant to the amount of darkness.
A graph titled Plant Growth has hours of darkness on the x-axis, and height of plant (inches) on the y-axis. Points are grouped closely together and decrease. Point (17, 12) is above the cluster.
Which statement about the scatterplot is true?
The point (17, 12) could cause the description of the data set to be overstated.
The point (17, 12) could cause the description of the data set to be understated.
The point (17, 12) shows that there is no relationship between the number of hours of darkness and the height of the plant.
Although (17, 12) is an extreme value, it should be part of the description of the relationship bet
Answer:
B. The point (17, 12) could cause the description of the data set to be understated.
Step-by-step explanation:
All other points on the scatter plot except point (17, 12), all follow a similar trend showing the negative relation between height of plants and darkness. If we are to consider just point (17, 12) alone when describing the data set, we might likely understate the relation between both variables.
Therefore, the statement that is true about the scatter plot is "B. The point (17, 12) could cause the description of the data set to be understated."

An aquarium holds 11.59 cubic feet of water, and is 2.2 feet long and 1.2 feet wide. What is its depth? Round your answers to the nearest whole number.
Answer:
4 feet deep
Step-by-step explanation:
to find the Volume of a rectangle you use the formula Bh=V
where B is the surface area of your base and h is the height, or depth as they call it in this case. using some algebra we divide the B over so now the equation read h=V/B, you know that the volume is equal to 11.59, so plug that into the equation, h=11.59/B. you dont have your base already given but the formula for the base is Lw=B or length times width, so you have 2.2*1.2=B. you can now sub that into the equation, which now reads, h=11.59/(2.2*1.2) now simply solve using a calculator, or you could do it by hand if you want, but it simplifies down to 4.3901515... so rounding it to the nearest whole number would be 4

A puppy weighed 1500 grams when it was born. Its weight increased by 28% during the first month. The puppy's weight at the end of the first month will be 1920 grams.
How to find how much percent 'a' is of 'b'?Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
A puppy weighed 1500 grams when it was born.
Its weight increased by 28% during the first month.
28% of 1500
= 0.28 x 100
= 420.
so add it to 1500
1500 + 420
= 1920
Therefore, the puppy's weight at the end of the first month will be 1920 grams.

Question 2:
[tex]\frac{tan\theta +sin \theta}{tan\theta - sin\theta} =\frac{sec\theta +1 }{sec \theta -1}[/tex]
Answer:

(cosθ - sin²θ + 1) / sinθ(1 + cosθ) = (cosθ + cos²θ) / sinθ(1 + cosθ) = cosθ(1 + cosθ) / sinθ(1 + cosθ) = cosθ / sinθ =cotθQuestion 2
(tanθ + sinθ) / (tanθ - sinθ) = (sinθ/cosθ + sinθ) / (sinθ/cosθ - sinθ) = sinθ(1/cosθ + 1) / sinθ(1/cosθ - 1) = (1/cosθ + 1) / (1/cosθ - 1) = (secθ + 1) / (secθ - 1)Please find attached herewith the solutions of your questions.
