Help Please Mathhh!!!!!!!!!!!!!!!

Answer:

The Answer is yes to both of your questions.

Step-by-step explanation:

SSS (Side angle Side) = Because If 3 sides of triangle are congruent to 3 sides of another triangle, the triangles are congruent. SAS (Side angle side) = If 2 sides and the angle in between are congruent to the corresponding parts of another triangle, the triangles are congruent.

Answer:

Step-by-step explanation:

A: Yes, it is 18.80%. Sample Mean= 135, Sample Standard deviation= 25/sq rt of 10 = 7.906, normalcdf(142, 999999, 135, 7.906) = .18796 × 100 = 18.796 = 18.80%

B: If we increase the sample size to 50, then, due to the Central Limit Therme, there should be less variation within the data (it should point to a more clear center). Sample Mean= 135, Sample Standard deviation= 25/sq rt of 50 = 3.535, normalcdf(142, 999999, 135, 3.535) = .02385 × 100 = 2.385 = 2.39%

The probability that the mean playtime is more than 142 seconds for an SRS of 10 videos is not accurately calculated and the probability that the mean playtime is more than 142 seconds is 0.0244.

Given :

A) The probability that the mean playtime is more than 142 seconds for an SRS of 10 videos is not accurately calculated because the sample size is too small due to which the central limit theorem cannot be applied.

B) According to the given data, the sample size is 50.

[tex]P(\bar{X}>142)=P\left(\dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n} }}>\dfrac{142-\mu}{\dfrac{\sigma}{\sqrt{n} }}\right)[/tex]

[tex]P(\bar{X}>142)=P\left(Z>\dfrac{142-135}{\dfrac{25}{\sqrt{50} }}\right)[/tex]

[tex]P(\bar{X}>142)=P\left(Z>1.9798\right)[/tex]

Using the z table the above expression becomes:

[tex]P(\bar{X}>142)=0.0244[/tex]

h^2=p^2+b^2

5^2=3^2+b^2

25-9=b^2

b=√16=4

radius=4

diameter=4×2=8

Answer:

Step-by-step explanation:

Word problem is a topic in mathematics that involves the interpretation of a given question with a mathematical expression so as to determine the value of the required variable.

Example: The price of a pencil is $10, and that of a ruler is $15.25. If Charles bought 5 pencils and 4 rulers, calculate the total amount of money spent.

price of a pencil = $10

price of a ruler = $15.25

Then,

cost of 5 pencils = $10 x 5

                            = $50

cost of 4 rulers = $15.25 x 4

                         = $61

Total amount of money spent by Charles = $50 + $61

                              = $111

The total amount of money spent by Charles is $111.

Answer: x=1/2

Step-by-step explanation: You want to get the x on one side of the equal sign, by itself. First you subtract (18/4) from both sides. 5 - (18/4) =1/2 So that’s your answer.

Answer:

Let one number be x and the other be (x-5)

Step-by-step explanation:

x^2+(x-5)^2=193

x^2+x^2-10x+25=193

2x^2-10x+25=193

Subtract 193 from both sides of the equation.

2x^2-10x-168=0

x=12 or x=-7

x-5=7 or x-5=-12

$3.60 times 2 is $7.20

3. The class median is lower than the exam median

Step-by-step explanation:

The median of the box plot is indicated by the vertical line that divides the box.

Thus, the Class median grade is about 80, while the Exam median grade is more than 80.

Comparing grades, this means that the class median is lower. than the exam median.

Therefore, "the class median is lower than the exam median" is the right information that describes the median.

Answer:

Step-by-step explanation:

find the inverse of the function y=9x+12

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=9x+12 becomes x=9y+12.

Now, solve the equation x=9y+12 for y.

[tex]f^{-1}[/tex](x) = (x-12)/9

y=(x−12)/9
