A nickel is selected at random out of a bag containing 15 pennies, 10 nickels, and 15 dimes. What is the probability of the complement of the event? Express your answer as a fraction in simplest form.
The probability of the complement of the event is 3/4 if the nickel is selected at random out of a bag containing 15 pennies, 10 nickels, and 15 dimes.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total number of contains in the bag = 15+10+15 = 40
Total number of nickel = 10
The probability of getting the nickel = 10/40 = 1/4
The complement of the probability:
P' = 1 – 1/4
P' = 3/4
Thus, the probability of the complement of the event is 3/4 if the nickel is selected at random out of a bag containing 15 pennies, 10 nickels, and 15 dimes.

A box of chocolates contains 18 chocolate squares. 10 of the squares are milk chocolate. 5 are dark chocolate and 3 are white chocolate if christina randomly chooses a chocolate out of the box, what is the probability of her choosing a white chocolate square
Answer:
Either %16.67 or %17 if rounded
Step-by-step explanation:.
An easy way to do this is convert the probability from a fraction into a percent. We can do this by taking the total number of chocolate squares (18) and using this as a denominator. Then take the number of white chocolate squares (3) and using this as our numerator. This give us a fraction of 3/18. Now to turn this into a percent, we need to find what you need to multiply 18 by to get 100. We can do this easily by deviding 100 by 18. This is a long decimal so i'll keep it in fraction form (100/18). Now you just have to multiply 3 by (100/18). This is about 16.67. If the answers are rounded it will be 17%.

Mike is working on solving the exponential equation 37x = 12; however, he is not quite sure where to start. Using complete sentences, describe to Mike how to solve this equation.
Use the change of base formula: log base b of y equals log y over log b.
[tex]~~~~~37^x = 12\\\\\implies \ln\left( 37^x \right) = \ln(12)\\\\\implies x \ln (37) = \ln(12)\\\\\implies x = \dfrac{\ln(12)}{\ln(37)}\\\\\implies x \approx 0.689[/tex]

based on a survey of 425 master’s programs in business administration, the u. s. news & world report ranked the indiana university kelley business school as the 20th best business program in the country (america’s best graduate schools, 2009). the ranking was based in part on surveys of business school deans and corporate recruiters. each survey respondent was asked to rate the overall academic quality of the master’s program on a scale from 1 “marginal” to 5 “outstanding.” use the sample of responses shown below to compute the weighted mean score for the business school deans and the corporate recruiters. discuss.quality business school corporate assessment deans recruiters 5 44 31 4 66 34 3 60 43 2 10 12 1 0 0
The deans have a higher weighted mean score for business schools which is 3.8.
What is weighed mean?The weighted arithmetic mean is similar to the conventional arithmetic mean in that certain data points contribute more than others to the final average.
Weighed mean = (weightage x parameter)/no of parameters
The Weighted mean score for deans
= [(5×44)+(4×66)+(3×60)+(2×10)]/(44+66+60+10)
= 684/180
= 3.8
The Mean weigted score of recruiters
= [(5×31)+(4×34)+(3×43)+(2×12)]/(31+34+43+12)
= 444/120
= 3.7

Total Volume grain elevator holds - 20357.52
Volume needed for 100-acre field - This is all you need to find. If the volume is more than what the grain elevator can hold than there will need to be a rented one as well. If the volume of the grain is lower than what the grain elevator holds, than that's all you need.
Step-by-step explanation:
You have to find how much volume you would need to hold harvest from a 100-acre field.
Then you have to find how much volume is in the grain elevator.
In order to find the volume of the grain elevator you have to divide it up by the cylinder and the cone.
Cone volume - V=πr^2(h/3)
V=2035.75
Cylinder volume - V=πr^2h
V=18321.77

Which of the following is a quadratic equation that has the roots x = 2 and x = −7? (4 points)
Answer:
x^2 + 5x - 14
Step-by-step explanation:
We can assume that if there is 2 options for x, this is a quadratic equation that equals 0.
Therefore, we can put this into brackets as one bracket must equal 0.
(x - 2) (x + 7)
After this we expand, which is a process easier to search up
The answer is:
x^2 + 7x - 2x - 14
We can simplify this to:
x^2 + 5x - 14
x^2 represents x squared in case you were wondering
Therefore, the answer is:
x^2 + 5x - 14

find the area of a square whose perimeter is 840m
Answer:
Area of square = 44,100 m²Step-by-step explanation:
Given :-
Perimeter of square = 840 cmTo find :-
Area of sqaureSolution :-
The find area of sqaure firstly we need to find the length of each side of the sqaure.
We know that,
Perimeter of rectangle = 4 × side
→ 840 = 4 × side
→ 840/4 = side
→ 210 m = side
Side of square is 210 m→ Area of rectangle = (Side)²
→ Area = (210)²
→ Area = 44,100 m²
Hence, Area of the square is 44,100 m²Hey ! there
Answer:
Area of square is 44100 m² .Step-by-step explanation:
In this question we are provided with a square having perimeter of square 840 m . And we are asked to find the area of square .
For finding area of square we need to find the side of square . So , we are finding the side of square by assuming it as " x " metres and then equating it with given perimeter that is 840 m .
We know that ,
[tex] \qquad \quad \underline{\boxed{\frak{Perimeter_{(Square)} = 4 \times Side }}}[/tex]
SOLUTION : -
✼ Finding Side ,
Substituting value of side as x in formula and equating it with 840 :
[tex] \quad \longmapsto \qquad \: 4 \times x = 840[/tex]
or ,
[tex] \quad \longmapsto \qquad \:4x = 840[/tex]
Dividing with 4 on both sides :
[tex] \quad \longmapsto \qquad \: \dfrac{ \cancel{4}x}{ \cancel{4}} = \cancel{ \dfrac{840}{4} }[/tex]
We get ,
[tex] \quad \longmapsto \qquad \: \underline{\boxed{\frak{x= 210 \: m}}}[/tex]
Therefore , SIDE of square is " 210 " metres .
✼ Finding Area ,
We know that ,
[tex] \: \qquad \: \qquad \: \underline{\boxed{\frak{Area_{(Square)} = Side {}^{2} }}}[/tex]
Now , substituting value of side as 210 in formula :
[tex] \quad \dashrightarrow \qquad \: (210) {}^{2} [/tex]
or ,
[tex] \quad \dashrightarrow \qquad \:210 \times 210[/tex]
Multiplying 210 two times , We get :
[tex] \quad \dashrightarrow \qquad \:\blue{\underline{\boxed{\frak{44100 \: m {}^{2} }}}} \quad \bigstar[/tex]
Henceforth , AREA of square having perimeter 840 m is ❝ 44100 square metres ❞
