Diameter of baseball is 3 inch
So, Radius of Baseball will be
Radius = Diameter/2Radius = 3/2 inch
Radius = 1.5 inch
we have been asked to determine the surface area of given baseball .
Using Formulae
[tex] \boxed {\bf \: Surface \: Area_{(Baseball)} \: = 4 \pi {r}^{2} }[/tex]
substituting the value and let's solve it
[tex] \longrightarrow\tt \:Surface \: Area_{(Baseball)} \: = 4 \times 3.14 \times {1.5}^{2} \\ \\ \\ \longrightarrow\tt \:Surface \: Area_{(Baseball)} \: = \: 4 \times 3.14 \times 2.25 \\ \\ \\ \longrightarrow\tt \:Surface \: Area_{(Baseball)} \: = \: 12.56 \times 2.25 \\ \\ \\ \longrightarrow\tt \:Surface \: Area_{(Baseball)} \: = \: 28.26 \: {inch}^{2} [/tex]
Therefore,
Surface Area of baseball is 28.26 sq. inch .So, your answer is 28.26 sq.in
A brand new vehicle costs $25,399. It decreases in value by 8.5% each year after its purchase.
Which function models the value of the vehicle in dollars x years after its purchase?
f(x)=1.085(25,399)x
f(x)=0.915(25,399)x
f(x)=25,399(0.915)x
f(x)=25,399(1.085)x
Answers
The cost after x years is the initial cost minus the amount of decrease after the duration of x years
Percentage DecreaseGiven Data
Initial Cost of vehicle = $25,399Rate of decrease = 8.5%Duration = yearlyLet us find 8.5% of $25,399
= 8.5/100*$25,399
= 0.085*25399
= 2158.915
Cost after x years will be

Answer: (x - 2)^2 + (y + 3)^2 = 18 3(2^(1/2)) (2,-3)
Step-by-step explanation:
7x^2 - 28x + 7y^2 + 42y - 35 = 0
divide 7 out
x^2 - 4x + y^2 + 6y - 5 = 0
add 5 to other side
x^2 - 4x + y^2 + 6y = 5
solve by completing the square
take b values divide them by 2 square and add to both sides
-4/2 = -2
-2^2 = 4
6/2 = 3
3^2 = 9
X^2 - 4x + 4 + y^2 + 6y +9 = 4 + 9 +5
(x - 2)^2 + (y + 3)^2 = 18

Mr. Red's salary is an illustration of an arithmetic sequence
The recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000
How to determine the recursive formula?From the complete question, we have the explicit rule of Mr. Red's salary to be
an = 500n + 29500
Where:
First term, a1 = 30000Common difference, d = 500The above means that:
The difference between a term and the next term is 500.
So, the recursive rule is:
an = an−1 + 500
Recall that:
a1 = 30000
Hence, the recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000

Step-by-step explanation:
A dilation is a transformation that makes an image that is thr same shape as the original, but a DIFFERENT SIZE.
Congruent shapes means they both have the same shape AND size.

A company is sued for job discrimination because only 39% of the newly hired candidates were minorities or women when 47% of all applicants were minorities or women. Is this strong evidence that the company’s hiring practices were discriminatory? a) Is this a one-tailed or two-tailed test? b) In this context what is a Type I error? c) In this context what is a Type II error? d) Which type error would the company consider to be more serious? e) Which type error might job applicants consider to be more serious?
Answers
The research is a one-tailed test because the company won't be sued if many minorities were hired.
How to illustrate the research?In the context, the type I error will be deciding the company is discriminating or not. The type II error will be deciding the company is not discriminating when it is.
The power of the test is the probability of correctly detecting actual discrimination. The type of error that the company consider to be more serious is the type I error.
In conclusion, the type of error that job applicants might consider to be more serious is type II error.

In the bag, there are : 4 blue and 5 red marblesProbability of blue (1st time)
P(1) = Total blue / Total marblesP(1) = 4 / (4 + 5)P(1) = 4/9Probability of blue (2nd time)
P(2) = Total blue / Total MarblesIt states it is replaced hence it is of the same constitution as the beginningP(2) = 4/9Probability of blue (both times)
