A jar is filled with pennies, nickels, and dimes. The probability of picking a penny is 1/4, and the probability of picking a dime is 1/3. What is the probability of picking a nickel? Write your answer as a decimal rounded to the hundredths place.
Answer:
What Are The Options?
Step-by-step explanation:
Answer:
0.42
Step-by-step explanation:
given:
P (penny) = 1/4
P (dime) = 1/3
since the only other possibility is to pick a nickel, hence
P (nickel)
= 1 - 1/4 - 1/3
= 5/12
= 0.4166667
= 0.42 (nearest hundredth)
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)Please help with questions will give brainlsest

X = 6
Step-by-step explanation:
Am tired 2 show the work
Answer:
=-6
Step-by-step explanation:
Move all terms containing x to the left side of the equation.
x−4=−10
Move all terms not containing x to the right side of the equation.
Add 4 to both sides of the equation.
x=−10+4
Add −10 and 4
X=-6
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.

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)

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]

What is the volume of the following rectangular prism
Answer:
8 1/8 or 8.125
Step-by-step explanation:
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
since we only have length and width we just multiply that
16 1/4 x 1/2 = 8 1/8 or 8.125
so the volume is 8 1/8 0r 8.125
