47.5% of children say that chocolate chip cookie is their favorite kind of cookie. If you randomly select 12 children find the probability that: a) at least 10 of them say that chocolate chip cookie is their favorite cookie. B) four of them say that chocolate chip cookie is their favorite cookie. C) Find the mean and standard deviation for this sample.
Answer: a) 0.0125 b) 0.1454 c) Mean = 5.7, standard deviation = 1.73
Step-by-step explanation:
Let x = Number of children say that chocolate chip cookie is their favorite kind of cookie.
x follows binomial distribution.
Binomila distribution formula:
[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex] , where p = probability in each trial, n = sample size, x= number of successes
Sample size : n= 12, p=0.475
a)
[tex]P(x\geg10)= P(x=10)+P(x=11)+P(x=12)\\\\=\ ^{12}C_{10}(0.475)^{10}(1-0.475)^{2}+^{12}C_{11}(0.475)^{11}(1-0.475)^{1}+^{12}C_{12}(0.475)^{12}(1-0.475)^{0}\\\\=\dfrac{12!}{2!10!}(0.475)^{10}(0.525)^{2}+(12)(0.475)^{11}(0.525)^{1}+(1)(0.475)^{12}\\\\\approx0.0125[/tex]
b)
[tex]P(x=4)= ^{12}C_{4}(0.475)^4(0.525)^{8}\\\\=\dfrac{12!}{4!8!}(0.000293798)\\\\=0.1454[/tex]
c) Mean = np
= (12)(0.475) =5.7
Standard deviation = [tex]\sqrt{np(1-p)}[/tex]
[tex]=\sqrt{12\times0.475\times0.525}\\\\=\sqrt{2.9925}\approx1.73[/tex]

A circle's circumference is approximately 88 cm. Estimate the diameter, rounding to the nearest WHOLE number. (don't forget your units and use 3.14 if you need to use )
Answer:
diameter = 28 cm
Step-by-step explanation:
circumference = 2πr
88 cm = 2 * 3.14.*r. ( π = 3.14 )
r = ( 88)/(3.14*2)
r = 14 cm
diameter = 2 * radius
diameter = 2 * 14 cm
diameter = 28 cm
Answer:
28 cmStep-by-step explanation:
Circumference formula:
C = πdSubstitute values of circumference and the π to find the diameter:
d = C/πd = 88/3.14 = 28 cm (rounded)Will give brainliest to first answer

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply A. 160 shirts cost $20
B. 20 shirts cost $160
C. 20,160 shirts cost money
D. The total cost of shirts is 20,160
Answer:
option B is correct option.
Step-by-step explanation:
Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply
Looking at the graph we come to know that 20 shirts cost $160 because x -axis represent number of shirts and y-axis represent Total Cost
So, the point(20,160) means x = 20 and y=160
We have 20 shirts and the cost is $160
So, option B is correct option.
In a group of 60 students, 15 liked maths only, 20 liked science only and 5 did not liked any of two subjects. How many of them liked at least one subject?
Answer:
35
Step-by-step explanation:
Given
n (A) = 15
n (B) = 20
Students who do not like any subject = 5
Hence, number of students who would like either both or either of the two subjects = 60-5 = 55
n (A or B) = n (A) + n (B) - n (A and B)
Number of students linking both the subjects
55 - 15-20
= 55-35 = 20
Number of students linking only one subject = 60-20-5 = 35
BRAINLIEST FOR THE CORRECT AWNSER!! PLEASE PUT THE LETTER AWNSER AND EXPLAIN DO NOT LIE THANK YOU What is the goal of a proof by contradiction? A. The contradiction of the statement is proven false, so the original statement is therefore proven true. B. The contradiction of the statement cannot be determined, so the proof is invalid. C. The truth of the statement cannot be determined, so the proof is invalid. D. The contradiction of the statement is proven true, so the original statement is therefore proven false.
Answer:
A
Step-by-step explanation:
We assume the opposite and then get to a point where we get a false statement. That proves that the the opposite of the opposite (What we originally wanted to prove) is true.

Answer: (-2,1) is the coordinate if rotated 270 degrees from origin.
Step-by-step explanation:
Answer:
A' = (-1,2)
Step-by-step explanation:
The other person is in fact incorrect. The reason why he/she is incorrect is because, it says "rotation about the origin." which means that is flips around the middle. 90 degree rotation would be (1,-2), a 180 degree rotation would be (-2,1), a 270 rotation would be (-1,2).
Therefore, your answer would be A' = (-1, 2)

F(2)=-5x+6 find value
Answer:
F(x) = 16
Step-by-step explanation:
F = 2. We find the value of -5x by inputting the value of the function into the x value.
F(x) = -5(2) + 6
F(x) = 10 + 6
F(x) = 16
