Jeremy goes to the store where he buys 18 bananas. After two days, he notices that there are only 10 bananas that are left. Which equation below would Jeremy use to find the percent of bananas that he has left?

A. 10/18 = 100/x
B. 18/10 = x/100
C. 5/9 = x/100
D. 10/18 = x/55.5

Answers

Total number of Bananas = 18
Number of Bananas that are left = 10

Percentage of Bananas that are left = x

Mathematically, x can be expressed as:

[tex]x= \frac{10}{18} * 100 \\ \\ \frac{x}{100}= \frac{10}{18} \\ \\ \frac{x}{100}= \frac{5}{9} [/tex]

Thus the correct percentage of number of bananas that are left is expressed by option c.

Ivan was given two data sets, one without an outlier and one with an outlier.

Data without an outlier: 108, 113, 105, 118, 124, 121, 109
Data with an outlier: 108, 113, 105, 118, 124, 121, 109, 61

How is the median affected by the outlier?

Answers

It make it 121 instead of 118 because there is an extra number and median is the middle of a data set so the number of numbers is important.

Answer:

Median is decreased by the outlier or Outlier made median lower.

Step-by-step explanation:

First we calculate median of the data without an outlier:

Data in Ascending or increasing order ,

105 , 108 , 109 , 113 , 118 , 121 , 124

Now there are 7 terms so

Median = [tex]\frac{7+1}{2}^{th}\:term[/tex] = 4th term = 113

Now we find median of the data with outlier:

Data in ascending or descending order,

61 , 105 , 108 , 109 , 113 , 118 , 121 , 124

here no of terms are 8.

So, Median = [tex]\frac{(\frac{8}{2})^{th}+(\frac{8}{2}+1)^{th}}{2}[/tex]

= [tex]\frac{4^{th}+5^{th}}{2}=\frac{109+113}{2}[/tex]

= 111

So, Median is decreased by the outlier or Outlier made median lower.

Answers

Assuming "A= bh 2 12/13/5 "
means
given Area=A=bh/2, and
the triangle has sides 5, 12 and 13.
(see diagram attached).

Since (5,12,13) for a Pythagoras triplet, it is a right triangle.
(13^2=12^2+5^2 => 169=144+25)
The two legs are 5 and 12, respectively b & h.
So the area of the triangle is bh/2=5*12/2=30
If the measures are in metres, then the area is 30 m^2.

Your friend asks you to make picture frames and will give you 5 5 nickels for the first frame. You agree to help if she multiplies your payment by 5 5 for each frame completed. After 2 2 frames, you will receive 25 25 nickels, and after 3 3 frames, you will receive 125 125 nickels. What is the number of nickels for tenth frame?

Answers

Final answer:

To find the number of nickels for the tenth frame, we calculate 5 imes 5^9, which equals 9,765,625 nickels. This is a geometric sequence where the common ratio is 5, and the first term for the first frame is 5 nickels.

Explanation:

The question asks about the payment received for making picture frames where the payment is multiplied by 5 for each subsequent frame. To find out the number of nickels for the tenth frame, we can use the concept of geometric sequences, where each term is found by multiplying the previous term by a common ratio. The common ratio in this case is 5.

For the first frame, you get 5 nickels. For the second frame, 5 multiplied by 5 is 25 nickels. To find the payment for the tenth frame, we multiply the payment of the first frame by the common ratio to the power of the frame number minus one: 5 imes 5^(10-1) = 5 imes 5^9.

Calculating 5 to the power of 9 gives us 1,953,125. Multiplying this by 5 gives us 9,765,625 nickels for the tenth frame.

Find the area and the circumference of a circle with radius 2m. use the value 3.14, and do not round your answers. be sure to include the correct units in your answers.

Answers

The area of a circle is given by:
[tex]A_c = \pi r^2[/tex]
Plug and chug:
[tex]A_c = \pi (2)^2 = 12.56m^2[/tex]

Circumference is given by (d = 2r):
[tex]C_c = \pi d[/tex]
Plug and chug:
[tex]C_c = \pi (4) = 12.56m[/tex]

Those are your answers!

Final answer:

The area of a circle with a radius of 2m is 12.56 m² and the circumference is 12.56 m when using 3.14 for π, with both answers having two significant figures due to the radius given with two significant figures.

Explanation:

The area (A) and the circumference of a circle with radius 2m can be found using the formulas A = πr² and C = 2πr. Using 3.14 as the value for π, the calculations would be A = (3.14)(2m)² = 12.56 m² for the area, and C = 2(3.14)(2m) = 12.56 m for the circumference. It is important to note that when performing calculations, the result should have the same number of significant figures as the quantity with the fewest significant figures used in the calculation.

If 8 identical blackboards are to be divided among 4 schools, how many divisions are possible? how many if each school must receive at least 1 black- board?

Answers

We usually distribute smartboards instead of blackboards these days!

We have a stars and bars problem.

We represent the blackboards by n=8 stars, and divide into k=4 schools (A,B, C & D) using three bars. Two consecutive bars or a bar at the end means that school has no blackboards.

For example,
*|***|*|***
Means there are two schools with 1 blackboard, and two other ones with three blackboards. Another example:
|*||*******
will mean there are two schools (A &C) with no boards, and B will have one, while school D will have 7.

So the problem reduces to counting the number of ways we can put the three identical bars.

If there is no minimum number of boards for each school, then we can place the k=4 bars at n+1=8+1=9 locations each.
Using combination notation, there are
C(n+1, k-1)=C(8+1,4-1)=C(9,3)=9!/(3!(9-3)!)=84 ways of distributing 8 blackboards to 4 schools.

On the other hand, if there is a minimum of one board for each school, then each school will get one, leaving 4 to be distributed as above, in
C(4+1,4-1)=C(5,3)=5!/(3!(5-3)!)=10 ways.

The solution of the equation is x = ±3. 162.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Parts of an Equation

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables.

Given:

x² = 10

Now to solve the above equation we have to take the square root on both side, we get

√x² = √10

x= ±√10

x= ±3. 162 ( because root provides two values one is positive and other is negative)

Hence, the value of x is ±3. 162.

If male and female college students work an average of 15 hours per week during the school year and the standard deviation is 5.4 for male students and 2.3 for female students, what may we conclude?

Answers

The variance of hours males spend working is almost two times as large as females. 60% of those females are more likely to work between 12.7 to 17.3 hours while 60% of the males work between 9.6 to 20.3 hours based on one standard deviation.

Answer: the male sample is more spread than the female sample

Step-by-step explanation:

The mean is the same for both genres, but the standard deviation form males is bigger than the one for females.

This means that the data of the male students is more spread than the female data (so there are more male students that study more hours, but there also are more male students that study less hours).

So the general conclusion is that the male sample is more spread than the female sample

Crystal charges a flat fee of $10 plus an additional $5 per hour to babysit given the situation what is the range

Answers

Answer:

perhaps $10 to $10,810

Step-by-step explanation:

We assume Crystal may be willing to babysit for a period of up to 3 months (90 days), so 90×24 = 2160 hours. Her hourly fee for that period will be ...

... (2160 hours) × ($5/hour) = $10,800

That amount added her $10 initial charge may represent the upper limit of her pay. The lower limit will be the $10 initial charge.

_____

Comment on the question

Since no upper limit on hours is given, we conclude the problem is not well-specified.

We can make a variety of different assumptions regarding the upper limit of babysitting time.

We might choose to consider this a daily charge, so the upper limit is $130 per day. We might consider that Crystal is willing to babysit while the child's parents are on a 2-week vacation. We might consider that Crystal is willing to babysit for the duration of her summer vacation from school (about 3 months). This is the assumption we use here.

what is the least common denominator of the rational expressions below?

a. x(x+7)(x+3)
b. x+7
c. x(x+7)^2(x+3)
d. x(x+3)

Answers

The first thing we need to do is factor the denominators in the rational expressions.
Notice that in the denominator of the first rational expression we have a common factor [tex]x[/tex], so we can factor x out:
[tex] x^{2} +7x=x(x+7)[/tex]
Now, the denominator of the second rational expression is a quadratic polynomial, we can factor it by finding tow numbers whose product will 21 and its sum will be 10. Those numbers are 7 and 3, (7x3=21 and 7+3=10):
[tex] x^{2} +10x+21=(x+7)(x+3)[/tex]

Lets rewrite our rational expression with our factored denominators:
[tex] \frac{6}{ x(x+7)} - \frac{8}{(x+7)(x+3)} [/tex]

Now, to find the least common denominator we are going to take one of the common factors (x+7) and all the non-common factors: x and (x+3):
[tex]x(x+7)(x+3)[/tex]

We can conclude that the correct answer is a. x(x+7)(x+3)
