Not choosing a presidential dollar can occur in 7 ways

Calculating Number of ways for choice

Given : Total 10 coins - 5 susan anthony dollars, 2 kennedy half dollars, 3 presidential dollars

To calculate : Number of ways through which non presidential dollar can be chosen

It can be calculated using Combination Choices

The dollar chosen is out of 7 dollars - 5 susan anthony dollars & 2 kennedy half dollars, ignoring & excluding the presidential dollars

So, number of ways = 7 c 1

= 7 ways

Answer: The boundary lines are correct, but there shouldn't be any shaded region

==========================================================

Explanation:

The graph of [tex]y \le x-1[/tex] will have us graph the boundary line y = x-1, and then shade below this solid boundary line. The boundary line y = x-1 is shown as the bottom boundary line of that diagram.

The graph of [tex]y \ge x+3[/tex] involves the boundary line y = x+3, with shading above the boundary line. The graph of y = x+3 is shown as the top boundary line of that diagram.

The boundary lines are correctly graphed, but the shaded region is incorrect. Instead, there shouldn't be any shaded region. The two shaded regions mentioned in the previous paragraphs do not overlap at all, so we don't have any (x,y) point that is in both shaded regions simultaneously. Therefore, there are no solutions to this entire system.

-----------------------------

Here's another reason why there's no solution region.

For each given inequality, subtract x from both sides

So [tex]y \le x-1[/tex] turns into [tex]y-x \le -1[/tex], while [tex]y \ge x+3[/tex] turns into [tex]y-x \ge 3[/tex]

Next, let z = y-x

We can replace each copy of 'y-x' with 'z' and we end up with the two inequalities [tex]z \le -1[/tex] and [tex]z \ge 3[/tex]

However, no such number is both -1 or smaller, AND 3 or larger

So there is no solution to that system involving z. Consequently, there are no solutions to the original system of inequalities.

Answer: They call it the “21” century because you have to count the first 100 years too, And do you mean 2021?

Step-by-step explanation:

Answer:

If you're talking about how it starts with 20 but its the 21st century, that's because the first 100 years were called the 1st century even though only the 2nd century actually started with 1.

Step-by-step explanation:

Answer:

y=11/5

Step-by-step explanation:

first divide by 5 on both sides

y+2/5=-13/5

subtract 2/5 on both sides to isolate the y

y=11/5

:))

Answer:

y=-3

Step-by-step explanation:

5(y+2/5) = -13

5y+2 = -13

subtract 2 from each side

5y+2-2 = -13-2

5y = -15

divide each side by 5

5y/5 = -15/5

y=-3

check:

5(y+2/5) = -13

substitute -3 for y

5(-3)+2/5) = -13

-15+2= -13

-13 = -13

I apologize if any of my answers are wrong.

For #1, WT is the same at WU, so the answer should be 7 inches

For #2, it looks like QT is just WT+QW. 7+16 is 23. Answer is 23 inches

For #3, PW is the same as QW so we can automatically assume the answer is 16 inches.

For #4, PU is the same at QT, so 23 inches

For #5, I'm pretty sure the distance between TR is the same as PT, so 8 inches for #5

For #6, PR*2 or 8*2 is 16, so 16 inches

For #7, 14 inches

For #8, 19 inches

Answer:

x is less than or equal to 0

Step-by-step explanation:

- you need to multiply both sides of the inequality by 5/2

- then you reduce the numbers with the greatest common factor 5

- then you reduce the numbers with the greatest common factor 2

- any expression multiplied by 0 equals 0

- so you get x is less than or equal to 0

Answer:

C. Males Prefer thriller movies. I'm pretty sure. I'd need the photo.

Step-by-step explanation:

If you look at the graph you'll see that 56 males like thriller while only 18 of women like it. These two data points have a difference of 38, making it the largest difference than any other category, therefore, its the strongest.  

The females who prefer drama movies has the strongest association option (A) Females who prefer drama movies is correct.

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total the equency cell to total frequency.

We have:

A conditional relative frequency is given:

From the data:

Probability of Females preferring drama movies :

= n(Females who prefer drama)/n(females )

= 45/84 = 0.53

Probability of  Males preferring comedy movies :

n(males who prefer comedy) / n(males)

= 40/119 = 0.33

The probability of Males prefers thriller movies.

n(males who prefer prefer thriller ) / n(males)

= 56/119 = 0.47

The probability of Females prefers thriller movies.

n(females who prefer prefer thriller ) / n(females)

= 18/84 = 0.21

Thus, the females who prefer drama movies has the strongest association option (A) Females who prefer drama movies is correct.

Answer:

Step-by-step explanation:

∠L = 52

∠N  = 26

8) ∠M + ∠N = 180          {in trapezoid, LM // PN, co interior angles}

    ∠M +  26 = 180

              ∠M = 180 - 26

              ∠M = 154

11) ∠LPN + ∠L = 180        {in trapezoid, LM // PN, co interior angles}

     ∠LPN + 52 = 180

                ∠LPN = 180 - 52

∠LPN = 128

9)In ΔPAN,

∠PAN + ∠N + ∠NPA = 180 {Angle sum property}

90 + 26 + ∠NPA = 180

         116 + ∠NPA = 180

                  ∠NPA = 180 - 116

                   ∠NPA = 64

∠LPA + ∠NPA = ∠LPN

∠LPA +  64  = 128

            ∠LPA = 128 - 64

           ∠LPA = 64

10) ∠MAP = 90                    {PA ⊥ MN}

Step-by-step explanation:

The value of 23 % of 42 is 9.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be A = 42

Now , let the percentage of the number A = 23 %

And , the equation will be

The 23 % of the number be = y

So , y = 23 % of 42

And , the equation is

y = ( 23 / 100 ) x 42

y = 0.23 x 42

On simplifying the equation , we get

y = 9.66

y ≈ 9.7

Therefore, the value of y is 9.7

Hence , The value of 23 % of 42 is 9.7

Answer:

7 (6 as exponent)

Step-by-step explanation:

Given the repeated product of a number to be expressed in exponential terms, we take the number as the base and the number of times it is multiplied as the exponent or power.

As such, given 7 x 7 x 7 x 7 x7 x 7

the base is 7 and since the number of 7s being multiplied is 6, the result is

7 exponent 6 which may be written as 7^6

Answer:

85%

Step-by-step explanation:

Answer:

85% of the balls pitched them.

Step-by-step explanation:

When you want to figure out a percent, you need to take the number of successful outcomes divided by the total number of outcomes. So, in this case, you would take 17/20, which is 0.85. Move the decimal place two times over to the right and you get 85, which is 85%.

Answer:

Total Dolls would Evelyn have had if she had not lost them = 9 Dolls

Step-by-step explanation:

As given,

Total dolls Evelyn had = 9

Total dolls lost = [tex]\frac{1}{3}[/tex]× 9 = 3
