Answer:
A. 77
Step-by-step explanation:
The mode of a data set is the value that appears the most number of times.
Here, we see that all the values appear once, except for 77, which appears twice:
74, 73, 76, 77, 71, 68, 65, 77, 67, 66
Thus, the answer is A, 77.

Step-by-step explanation:
Simplify the following:
-(3 + 7/8) (-(4 + 3/5))
Hint: | Multiply all instances of -1 in -(3 + 7/8) (-(4 + 3/5)).
(-1)^2 = 1:
(4 + 3/5) (3 + 7/8)
Hint: | Put the fractions in 3 + 7/8 over a common denominator.
Put 3 + 7/8 over the common denominator 8. 3 + 7/8 = (8×3)/8 + 7/8:
(4 + 3/5) (8×3)/8 + 7/8
Hint: | Multiply 8 and 3 together.
8×3 = 24:
(4 + 3/5) (24/8 + 7/8)
Hint: | Add the fractions over a common denominator to a single fraction.
24/8 + 7/8 = (24 + 7)/8:
(4 + 3/5) (24 + 7)/8
Hint: | Evaluate 24 + 7 using long addition.

(4 + 3/5)×31/8
Hint: | Put the fractions in 4 + 3/5 over a common denominator.
Put 4 + 3/5 over the common denominator 5. 4 + 3/5 = (5×4)/5 + 3/5:
31/8 (5×4)/5 + 3/5
Hint: | Multiply 5 and 4 together.
5×4 = 20:
((20/5 + 3/5)×31)/8
Hint: | Add the fractions over a common denominator to a single fraction.
20/5 + 3/5 = (20 + 3)/5:
31/8 (20 + 3)/5
Hint: | Evaluate 20 + 3.
20 + 3 = 23:
23/5×31/8
Hint: | Express 23/5×31/8 as a single fraction.
23/5×31/8 = (23×31)/(5×8):
(23×31)/(5×8)

| - | 4 | 0 | |
| | 3 | 1 | 3 |
| - | 2 | 8 | 0 |
| | | 3 | 3 |
Hint: | Summarize the results.
Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
| | | 1 | 7 | (quotient)
4 | 0 | 7 | 1 | 3 |
| - | 4 | 0 | |
| | 3 | 1 | 3 |
| - | 2 | 8 | 0 |
| | | 3 | 3 | (remainder)
Hint: | In the equivalent mixed fraction, the quotient becomes the whole number part, the remainder becomes the numerator part, and the divisor (denominator) remains the denominator.
The quotient of 713/40 is 17 with remainder 33, so:

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
Suppose you want to scale the copy back to its original size. What scale factor should you use?
Answer:
1/7.
Step-by-step explanation:
You use the inverse of 7 which is 1/7.
In order to back to its original size, we need to take a scale factor of 1/7.
What is the scale factor?You must specify the extent of the shape's enlargement when describing one.
The scale factor is the ratio of two dimensions such that one figure is large and another is small.
The scale factor is done due to the unpractical measurement of any figure.
For example, 50 meters is very big so we cannot measure it but if we can convert it into 50 mm such that the scale ratio is maintained then it will be easy to draw.
If the rectangle is scaled by scale factor 7 it means it is plotted 7 times big such that a 7:1 scale factor maintain.
Now if we want to see the original rectangle then we need to take 7 times lower than that so a 1/7 scale factor is going to use.
Hence "In order to back to its original size, we need to take a scale factor of 1/7".

Fill in the blank. In a _______ distribution, the frequency of a class is replaced with a proportion or percent.
Answer:
Relative frequency
Step-by-step explanation:
In a relative frequency distribution, the frequency of a class is replaced with a proportion or percent.
A relative frequency distribution displays how the proportion of totality of the observations related to each class is correlated to the probability distribution. A relative frequency distribution shows the proportion of times a value occurs in each class. It can be determined by the division of the frequency with the total number of data values.

joey collects 100 seashells. 45% of them are pink. how many shells are not pink. how many are pink .
Answer:
45 are pink 55 are not pink
Step-by-step explanation:
a) The number of pink seashells is A = 45
b) The number of seashells that are not pink = 55
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the total number of seashells be = 100
Let the percentage of the seashells that are pink = 45 %
If 45% of the 100 seashells are pink, then the remaining 55% must be not pink. We can find the number of pink shells by multiplying 100 by 45%:
Number of pink shells = 100 x 0.45 = 45
To find the number of shells that are not pink, we can subtract the number of pink shells from the total number of shells:
Number of shells not pink = 100 - 45 = 55
Hence , there are 55 seashells that are not pink and 45 seashells that are pink.

PLZ ANSWER FAST!! CORRECT ANSWER GETS BRAINLIEST!!
Answer:
(Weight (lb), Price ($) ) = (0.45,2.3)
That means :
Weight (lb) = 0.45 when Price ($) = 2.31) So, if we want to find the price per pound, we'll divide 2.3 by 0.45:
=> [tex]\frac{\$ 2.3}{0.45 \ lb}[/tex] [True]
2) Second Statement: [False]
The weight of every 0.45 lb of bag is 2.3 pounds not for per bag.
3) Third Statement: [False]
2.3 pounds of almonds cost $0.45
This is incorrect according to the graph.
4) Fourth Statement: [False]
Almonds cost $0.45 per pound
Let's check it out
0.45 lb = $2.3
Dividing both sides by 0.45
1 lb = $5.11
It is not $4.5
5) Fifth Statement: [True]
0.45 pounds of almond costs $2.30
For every 0.45 pounds, there are $2.30 . So, this statement is true!
1. A recent study revealed that 45% of business travelers plan their own business trips. The study is to be replicated with a sample of 12 frequent business travels. a. What is the probability exactly 5 travelers plan their own trips
Answer:
The probability is [tex]P(X = 5) = 0.222[/tex]
Step-by-step explanation:
From the question we are told that
The proportion of business travelers that plan their own business trip is [tex]p = 0.45[/tex]
The sample size is n = 12
The random number considered is x = 5
Generally the proportion of business travelers that do not plan their own business trip is mathematically evaluated as
[tex]q = 1- p[/tex]
=> [tex]q = 1-0.45[/tex]
=> [tex]q = 0.55[/tex]
This can study can be said to follow binomial distribution as there is only two outcomes
So the probability exactly 5 travelers plan their own trips is mathematically represented as
[tex]P(X = 5) = ^{12} C_5 * p^5 * q^{12- 5 }[/tex]
Generally using a combination calculator
[tex]^{12} C_5 = 792[/tex]
So
[tex]P(X = 5) = 792 * (0.45)^5 * (0.45)^{12- 5 }[/tex]
[tex]P(X = 5) = 0.222[/tex]

Number between 17/4 and square root of 20
Answer: 4.485
Step-by-step explanation:
We need to find the number between [tex]\dfrac {17}{4}[/tex] and [tex]\sqrt{20}[/tex].
For this , we first simplify the above numbers.
[tex]\dfrac{17}{4}= 4.25[/tex] [divide 17 by 4]
[tex]\sqrt{20}=\sqrt{4\times5}=2\sqrt{5}= 2(2.236)=4.472[/tex] [ [tex]\sqrt{5}=2.236[/tex] ]
Now, Midpoint of 4.25 and 4.472 = [tex]\dfrac{4.25+4.72}{2}=\dfrac{8.97}{2}=4.485[/tex]
Number between 4.25 and 4.472 =4.485
Or number between [tex]\dfrac {17}{4}[/tex] and [tex]\sqrt{20}[/tex] is 4.485.
A parallelogram has an area of 28 square feet and a height of 4 feet. What is its base?
Answer:
7
Step-by-step explanation:
The area for a parallelogram is given by the following formula:
[tex]A=bh[/tex]
Where b is the base and h is the height.
We already know the area is 28 and the height is 4. So, substitute:
[tex]28=4b[/tex]
Divide both sides by 4:
[tex]b=7[/tex]
So, the base length is 7.
Our answer is 7 :)
Hey there! I'm happy to help!
The area of a parallelogram is just the base multiplied by the height. If the area is 28 square feet, we will divide it by our height to find the base.
28/4=7
Therefore, our base is 7 feet.

Option D is the correct option.
Step-by-step explanation:
[tex] \sf{12x + 4y = 20}[/tex]
Move 12x to right hand side and change it's sign
⇒[tex] \sf{4y = - 12x + 20}[/tex]
Divide both sides of the equation by 4
⇒[tex] \sf{ \frac{4y}{y} = \frac{ - 12x + 20}{4} }[/tex]
⇒[tex] \sf{y = \frac{ - 12x}{4} + \frac{20}{4} }[/tex]
Divide -12x by 4 . Also divide 20 by 4
⇒[tex] \sf{y = - 3x + 5}[/tex]
