Answer:
The correct option is (C) 10.
Step-by-step explanation:
The five-number summary for the number of teams in each of Brad's fantasy football leagues is as follows:
Minimum: 4
Q₁: 7
Median: 10
Q₃: 14
Maximum: 18
The minimum value is the smallest value in the data set.
The first quartile (Q₁) is the value that is less than 75% of the observations.
The median is the middle most value of the data set. It is the value that is less than 50% of the observations.
The third quartile (Q₃) is the value that is less than 25% of the observations.
And the maximum value is the largest value in the data set.
So, the five-number summary suggests that about 50% of Brad's fantasy football leagues have fewer than 10 teams.
Thus, the correct option is (C).
Estimate the square root to the nearest (a) integer and (b) tenth.

It will snow in July in Phoenix, Arizona.
If you roll a die, it will come up with an even number.
If you flip a coin, it will come up either heads or tails.
The next child born in the United States will be a girl.
O
Answer:
C. If you flip a coin, it will come up either heads or tails.
Step-by-step explanation:
A. My guess is it doesn't rain much in Phoenix in July. A probability of 1 means it will happen for sure, so this is not it.
B. A die has 3 even numbers and 3 odd numbers. The probability of rolling an even number is 3/6 = 0.5. This is not it.
C. If you flip a coin, you either get heads or tails. The probability of heads or tails is 1 since one of the two outcomes will always happen. This is the answer.
D. The probability of the birth of a girl is 1 out of 2, so it is 0.5. This is not it.
Answer:
If you flip a coin, it will come up either heads or tails. It either will fall on heads or tails everytime so that is closest to one.

What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
Explanation:
Before solving the problem, we should understand what is the length that corresponds to one notch in the graph.
We see that there are 3 notches between 0 and 6, and that the length of the notches is constant: so, each notch corresponds to the same length. Since we have 3 notches, the length of each notch is
6/3 = 2
now, we have,
Since the car is located at the first notch, it means that its position is:
x = 1*2 = 2
Hence, The solution is, c. 2, is the position of the car.

A triangle has sides with lengths of 6 yards, 8 yards, and 10 yards. Is it a right triangle?
Answer:
Step-by-step explanation:
so, by the Pythagorean theorem
If it is a right triangle:
a^2 + b^2 = c^2
so,
6^2 = 36
8^2 = 64
10^2 = 100
okay, now we plug these into the equation
36 + 64 = 100
so yes, it is a right triangle.
Hope this helped!
Answer:
No, it's not a right triangle.
Explanation:
If you think about it a right triangle has 2 equal sides. So no this isn't a right traingle.

From the sample population of students with blond hair, what is the approximate value of the relative frequency of students with green eyes? A. 0.25 B. 0.33 C. 0.27 D. 0.07
Don't quote me on this but I think the answer is C. 0.27
The required approximate value of the relative frequency of students with green eyes is 0.27. Option C is correct.
From the sample population of students with blond hair, the approximate value of the relative frequency of students with green eyes is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Number of students having green eyes with blond hair =21
Total number of students having blond hair = 78
relative frequency of students with green eyes = 21/78
= 0.27
Thus, the required approximate value of the relative frequency of students with green eyes is 0.27.

Answer:
A. Trinomial
Step-by-step explanation:
It says it's a polynomial and that based on the number of terms. So right then you can cancel out cubic and quadratic because they aren't polynomials. Also:
Cubic is just a variable with the exponent of 3. Examples:

Binomial is a polynomial with 2 terms. Examples:

Median
Explanation:
The median is the middle number. This answer fits best with the question asked.
The mode is the number that occurs the most. This number doesn't really have a correlation to the middle of this data.
The range is just how many numbers the data spans across. It has no relation to the middle of the data.
Joe worked 42 hours and packed 48 cartons. Bob worked 14 hours and packed 16 cartons. Did Joe and Bob work at the same rate?
Answer:
Yes
Step-by-step explanation:
if you simplify. 42/48. 7/8
if you simplify 14/16 is 7/8 So they are equal
If Joe worked 42 hours and packed 48 cartons and Bob worked 14 hours and packed 16 cartons, Joe and Bob worked at the same rate.
To determine if Joe and Bob worked at the same rate, we need to compare the number of cartons they packed per hour. We can calculate the rate by dividing the number of cartons packed by the number of hours worked.
For Joe:
Rate = Number of cartons packed / Number of hours worked
Rate = 48 cartons / 42 hours ≈ 1.143 cartons per hour
For Bob:
Rate = Number of cartons packed / Number of hours worked
Rate = 16 cartons / 14 hours ≈ 1.143 cartons per hour
Both Joe and Bob have a packing rate of approximately 1.143 cartons per hour.
They packed almost the same number of cartons per hour on average. This indicates that their packing efficiency is similar, regardless of the difference in the total number of hours or cartons packed.

Which statement is not necessarily true
Answer:
Line PQ is congruent to Line QR
Step-by-step explanation:
To figure this out, you can use a process of elimination. A rectangle as 2 congruent parallel sides, thus eliminating the answer choice of "A" and "B." Also, a rectangle has four 90° angles, eliminating answer choice "C."
This statement isn't necessarily true because not all rectangles are squares, so this means that Line PQ won't always necessarily be congruent to Line QR.
The quadrilateral ABCD is a rhombus with diagonals AC = 12 ft and BD = 4 ft. The points M and N divide diagonal AC on three equal parts. Prove that BMDN is a square and find its area.
Answer:
area of BMDN 8 ft²
Step-by-step explanation:
In BMDN the diagonals are BD and MN.
MN is 12/3 = 4 ft long, and BD = 4 ft.
A rhombus with equal diagonals is a square, so BMDN is a square.
In the right triangle BDN, the diagonal BD is the hypotenuse, then:
DN² + NB² = BD²
but DN = NB, then:
2*DN² = 16 ft²
DN² = 8 ft²
The area of BMDN is computed as one of its sides squared. Then, DN² is its area

Solve for x: 2800 = 400 * 2^10x
it should be x=log(7)/10*log(2) and x=in(7)/10*in(2)
so B and D
The required solution for the expression is [tex]x = ln7/(10*ln2)[/tex]. Option D is correct
To solve [tex]2800 = 400.2^{10x}[/tex] for x.
what is an exponential function?The function which is in format f(x) = [tex]a^x[/tex] where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
[tex]2800 = 400.2^{10x}[/tex]
[tex]2800/400= 2^{10x}[/tex]
[tex]7=2^{10x}[/tex]
taking log on both sides.
[tex]log_27=10x\\x=log_27/10\\x = log_e7/(10*log_e2)\\x =ln7/(ln2*10)[/tex]
(By properties of logarithm log can be separated to common base e)
The required solution for the expression is [tex]x = ln7/(10*ln2)[/tex].
