Charlie and Clare are playing a number-guessing game. Charlie picked two numbers between 1 and 5. To win the game, Clare must guess both his numbers in three tries. Her guesses, simulated using a random-number generator, are shown in the table. If Charlie’s numbers are 1 and 3, what is the experimental probability that Clare won?

Satisfying the input format requirements of a computer is always problematic. One never knows if fractions or decimals are preferred, whether radicals must be simplified, and so on. If no clues are offered by general instructions, other questions, or previous experience, then it might be useful to consult your instructor.

Answer:

Answer:

x=3

Step-by-step explanation:

2/3x+15=17

first subtract 15 from both sides

2/3x=2

multiply by 3 to eliminate the fraction

2x=6

divide by 3

x=3

Answer:

x=3

Step-by-step explanation:

2/3x +15 = 17

2/3x = 17-15

2/3x = 2

x = 2  /  2/3

x = 2/1  *  3/2

x = 6/2

x = 3

Answer:

10i

Step-by-step explanation:

Step 1: Expand first 2

(1 + i)(2 + i)

2 + i + 2i + i²

2 + 3i + (-1)

1 + 3i

Step 2: Expand again

(1 + 3i)(3 + i)

3 + i + 9i + 3i²

3 + 10i + 3(-1)

3 + 10i - 3

10i

Answer:

n = 2.5

Step-by-step explanation:

We need to isolate n by first moving it to one side.

11n = 13n - 5

11n - 13n = -5

-2n = -5

n = -5/-2

n = 2.5

Answer:

n = 5/2

Step-by-step explanation:

5 + 11n = 13n

5 = 13n - 11n

5 = 2n

n = 5/2

Check:

5 + 11*5/2 = 13*5/2

10/2 +  55/2 = 65/2

Answer:

Use a graphing calc.

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

For the third equation, m = 2

y = 2x + b

3 = 3(2) + b

3 = 6 + b

b = -3

y = 2x - 3

Irrational Number

Step-by-step explanation:

The Venn diagram is not attached; However, the question can still be answered

Given

[tex]Number = 4\pi[/tex]

Required

What category of number is the given number

[tex]Number = 4\pi[/tex]

Substitute [tex]\frac{22}{7}[/tex] for [tex]\pi[/tex]

[tex]Number = 4 * \frac{22}{7}[/tex]

[tex]Number = \frac{4 *22}{7}[/tex]

[tex]Number = \frac{88}{7}[/tex]

[tex]Number = 12.5714285714......[/tex]

Notice that there's .... at the end of the number;

This implies that, the decimal number still extends

Numbers like 12.5714285714...... are categorized as irrational numbers because it can't be changed back to a fraction

Answer:

V= 68.6 m/s

Step-by-step explanation:

height above the ground t seconds after it is dropped is 675-4.9t^2

For seven seconds

Height above ground= 675-4.9(7)²

height above ground= 675-240.1

Height above ground= 434.9 m

But it's dropped from a cliff and we need to find the distance traveled from the too of the cliff

Distance= 675-434.9.

Distance= 240.1

To determine it's speed

V²= U² +2gs

V= velocity we are looking for

U= initial velocity= 0

G= acceleration due to gravity= 9.8 m/s²

s= distance covered

V²= U² +2gs

V²= 0+2(9.8)(240.1)

V²= 4705.96

V= 68.6 m/s

Answer:

  4.54

Step-by-step explanation:

The 4th digit (6) is greater than 4, so the 3rd digit (3) is increased by 1 before you drop the remaining digits:

  4.54

Answer:

See below.

Step-by-step explanation:

4)

So we have the expression:

[tex](-6n^{-3})^2[/tex]

We can use the power of a product property, where:

[tex](ab)^n=a^n\cdot b^n[/tex]

So:

[tex]=(-6)^2\cdot(n^{-3})^2[/tex]

For the left, -6 squared is the same as -6 times -6. This equals positive 36.

For the right, we can use the power of a power property. The property says that:

[tex](a^n)^k=a^{nk}[/tex]

So:

[tex](n^{-3})^2=n^{(-3)(2)}\\=n^{-6}[/tex]

So, all together, we have:

[tex]=(-6)^2\cdot(n^{-3})^2\\=36n^{-6}[/tex]

6)

We have the expression:

[tex]-\frac{3x^0}{x^4}[/tex]

First, note that anything to the zeroth power (except for 0) is 1, thus, x^0 is also 1. Simplify:

[tex]=-\frac{3}{x^4}[/tex]

And that's the simplest we can do :)

Notes for 6)

We can put the x^4 to the numerator. Recall that when you put an exponent to opposite side, you put a negative. In other words:

[tex]x^n=\frac{1}{x^{-n}}[/tex]

And vice versa:

[tex]\frac{1}{x^{-n}}=x^n[/tex]

So, we can write the above as:

[tex]=-\frac{3}{x^4}\\=-\frac{3}{x^{-(-4)}}\\=-3x^{-4}[/tex]

However, traditionally, we want only positive exponents, so this wouldn't be correct.

Answer:

Step-by-step explanation:

x^m×x^n=x^{m+n}

x^m÷x^n=x^{m-n}

[tex]\frac{1}{x^m} =x^{-m}\\x^{-n}=\frac{1}{x^n} \\(xyz)^m=x^m\times y^m \times z^m \\(x^m)^n=x^{mn}[/tex]

[tex]x^0=1[/tex]

Answer:

Step-by-step explanation:

Formula for calculating the surface area of the box S = 2(LW+LH+WH) where

L is the length of the box

W is the width of the box

H is the height of the box

If the box is square based with dimension 4 * 4in, then L = W = 4in. substituting this values given into the formula we will have;

S = 2(4(4)+4H + 4H)

S = 2(16+8H)

S = 32+16H

Hence, The function that represents the surface area of this box as a

function of its height is S = 32+16H where H is the height of the box

Given H = 6.5in, to evaluate the function, we will substitute h = 6.5in into the modeled equation;

S = 32+16H

S = 32+16(6.5)

S = 32+106

S = 138in²

Hence the total surface area of the box is 138in²

Answer:

1

Step-by-step explanation:

To find the answer of a negative and a positive, you subtract and then keep the symbol of the bigger number.  So in the equation 1-8 you subtract 1 from 8, then keep the symbol of the 8 (which is a negative) since it is the bigger number.  1 minus 8 is 7, and the symbol is negative, so the answer is -7.  This makes K=1.

Answer:

Mrs Taylor should buy 45.5 yards of fabric ( 45.5364 actually but rounded to the nearest tenth)

Step-by-step explanation:

Here in this question, we are interested in calculating the total yards of fabric that Mrs Taylor should buy.

From the question, we are made to know that one uniform requires 26 inch of fabrics and she wants to make a total of 63 uniforms

The total inches of fabric needed is thus; 26 * 63 = 1,638 inches of Fabrics

But we want our answer in yards.

Mathematically;

1 inch = 0.0278 yard

1638 inches = x yard

x = 1638 * 0.0278 = 45.5364 yards which is approximately 45.5yards

Answer:

9

Step-by-step explanation:

Working backwards, the blank box between the 7 and 4 at the end must be 9 in order for the three digits to equal 20.  Then we see the pattern of 947 repeated.  The whole number would be 94794794794794.  That way, any three consecutive numbers would be 20.  The number in the box marked a would be 9.
