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.

Z = -3.57

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:

[tex]x^3,y^3,z^3[/tex]

Binomial is a polynomial with 2 terms. Examples:

[tex]5x+3; 6x+2; x+7[/tex]

A quadratic has a division sign.

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.

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].

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.

C is correct

Hope this helps!

:)

If a system of linear equations has one solution, this means that the lines are intersecting lines

Intersecting lines are lines that meet at a point.

For parallel lines, they do not meet at any point. Hence the system of equation formed by these lines does not have a solution

For two intersecting lines, the equation of both lines can be equated to get the unknown variable. This unknown variable will serve as the solution to the system of equation

Hence If a system of linear equations has one solution, this means that the lines are intersecting lines

Answer:

The mean absolute deviation (MAD) of her Math scores would be 1.2.

Step-by-step explanation:

Mean: 5.4 + 6.4 + 7.8 + 8.8 = 28.4/4 = 7.1

7.1 - 5.4 = 1.7

7.1 - 6.4 = 0.7

7.1 - 7.8 = 0.7

7.1 - 8.8 = 1.7

Mean Absolute Deviation: 1.7 + 0.7 + 0.7 + 1.7 = 4.8/4 = 1.2

Step-by-step explanation:

The solution is, c. 2, is the position of the car.

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.

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.

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.
