He should conduct the experiment as many times as possible, more the better estimate can be obtained.

Record the no. of 6's and divide the no. of trials to get an estimate of the probability of 6

After many trials, the experimental probability would get closer and closer to the theoretical probability which is 1/8

Answer: 33 minutes

Step-by-step explanation:

Hi to answer this question we have to write a proportion

Speed rate = 88 step per minute

Time = 90 minutes

So, the proportion is 88 step/min / 90 minutes

For 33 steps per minutes = 33 / x minutes

88/90 = 33/x

solving for x:

x= 33/ (88/90)

x = 33.75 = 33 minutes.

Answer:

29%

Step-by-step explanation:

[tex] \frac{0.58}{2} \times 100 \\ [/tex]

29%

Percent decrease formula: new value - old value / old value

Solve with the given values.

2 - 1.42 / 2

0.58 / 2

0.29

Turn the decimal into a percentage.

0.29 * 100% = 29%

Therefore, there is a 29% decrease.

Best of Luck!

Answer: 5

Step-by-step explanation:

3x + 5=3x - 5

Final answer:

To achieve an infinite number of solutions in the equation '3x + 5 = 3x - ______', the blank should be filled with the number 5, making both sides of the equation identical and true for all values of x.

Explanation:

To make an equation have an infinite number of solutions, both sides of the equation must be identical. Looking at the equation 3x + 5 = 3x - ______, we want to find the number that would make the statement an identity.

The only way for this equation to have infinite solutions is if the variable terms (3x) are equal and the constant terms are also equal. Hence, the blank must be filled with the number 5, making the equation 3x + 5 = 3x + 5, which is true for all values of x.

Answer:

The length of the slide is 10 feet.

Step-by-step explanation:

To find the length of the slide you have to use the formula:

a^2 + b^2 = c^2 (^2 means squared)

In this case:

a= 6 and b=8 c= unknown

6 squared (6 times 6) is 36

8 squared (8 times 8) is 64

Add these two numbers to get:

36+64=100

6^2+8^2=100

However, the length of the slide in not 100 feet. In order to find the correct length you must find the square root of 100. Which is 10.

What number times itself equals 100? 10.

The length of the slide in 10 feet.

Answer:

no solutions

Step-by-step explanation:

A linear equation having same variable term on both RHS and LHS is not defined. The number of solutions for the equation 5 - 2x = 3 + x - 4 - 3x is zero.

A linear equation is can be defined as a equation that has its degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The given equation is as below,

5 - 2x = 3 + x - 4 - 3x

It can be simplified as,

5 - 2x = 7 - 2x

Since both LHS and RHS contain the same variable term 2x which can be cancelled out so that there will be no variables.

Thus, the given equation has no solutions.

Hence, the number of solutions for the given equation is zero.

Answer:

$137.50 for Liza with cents and 132 without any cents. $154 for marta wihtout cents and 165 dollars with cents. First try subtracting 137.50 from 165 and then try 154 subtract 132.

step-by-step explanation:

First you need to multiply 6 x 22 and you get your dollars! Then multiply 22 x 25 to get your cents. Also try to do it without any cents. Convert all your cents to dollars and add to your product. And multiply 7 x 22 to get the amount of dollars for marta and 50 x 22 to get the cents for marta. Also try it without cents like it could be right or wrong. Convert the cents to dollars. Lastly, subtract what marta got in 22 hours and liza got in 22 hours. Pick the closest answer.

Answer:

x = 1

Step-by-step explanation:

Triangle ABC is congruent to Angle DEF

13x - 12 = 7x - 6

6x = 6

x = 1

Answer:

x = 1

Step-by-step explanation:

These are congruent triangles

The single line is the same length in ABC as the single line in DEF

The double line is the same length in ABC as the double line in DEF

13x-12 is the same length as 7x-6

13x-12 = 7x-6

Subtract 7x from each side

13x-12 -7x =7x-6 -7x

6x-12 =-6

Add 12 to each side

6x-12+12 = -6+12

6x = 6

Divide each side by 6

6x/6 = 6/6

x = 6/6

x = 1

Here the first term of the sequence is = 11

Second term of the sequence is = 22

Third term of the sequence is = 44

Fourth term of the sequence is = 88.

............

Second term = 2×first term

Third term = 2 × Second term

Fourth term = 2 × Fourth term

The recursive rule for the sequence is

where n is positive integer.

Answer:

340 phones

Step-by-step explanation:

Make an expression

She repairs 10 phones each day, d.

Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.

450-10d

We want to find how many she has left after 11 days, so we can substitute 11 in for d

450-10(11)

Multiply

450-110

340

She will still have 340 phones left to repair

Katie would have repaired 110 phones by the end of the 11th day. She started with 450 phones, so after subtracting the number of repaired phones, she has 340 phones left to repair.

To determine the number of phones Katie has left to repair at the end of the 11th day, we need to calculate how many phones she has repaired so far. Since Katie repairs 10 phones every day, after 11 days, she will have repaired 10 phones/day * 11 days = 110 phones.

Katie starts with 450 phones at the beginning of the month. So, to find out how many are left un-repaired, you subtract the number of phones she has repaired from the starting amount.

Therefore, 450 phones - 110 phones = 340 phones are left to repair at the end of the 11th day.

Step-by-step explanation:

[tex]9,000-b=-11,000+b[/tex]

Regroup terms

[tex]9,000-b=b-11,000[/tex]

Add b to both sides

[tex]9,000-b+b=b+b-11,000\\9,000=2b-11,000[/tex]

Add 11,000 to both sides

[tex]9,000+11,000=2b-11,000+11,000\\9,000+11,000=2b[/tex]

The sum of the angles in a triangle is always 180 degrees. This fundamental concept helps in calculating unknown angles in triangles.

Triangle Angle Sum Theorem: The sum of the angles in a triangle is always equal to 180 degrees.

Explanation: In any triangle, the three interior angles add up to 180 degrees. This theorem is fundamental in geometry and can be used to solve for unknown angles in triangles.

Example: If two angles in a triangle are 30 degrees and 60 degrees, the third angle can be found by subtracting the sum of the given angles from 180, which gives 90 degrees.

To express 15 seconds as a fraction of 2 hours, first convert 2 hours to seconds, which is 7200 seconds. The fraction is thus 15 / 7200, and simplified, it is 1/480.

To express 15 seconds as a fraction of 2 hours, we need to convert both quantities to the same unit.

There are 60 seconds in a minute and 60 minutes in an hour, so 2 hours is equivalent to 2 × 60 × 60 = 7200 seconds.

The fraction representing 15 seconds out of 2 hours is therefore 15 / 7200.

Simplifying this fraction, we divide numerator and denominator by the greatest common divisor (15), which gives us 1 / 480. Thus, 15 seconds is 1/480 of 2 hours.

Now let's review some additional units of time:

For conversion, 1 hour is equal to 60 minutes, so if we have 100 minutes, we can represent it as 1 hour 40 minutes. Similarly, the sum of 1 hour 55 minutes and 45 minutes is 2 hours 40 minutes.

It's important to remember to start your subtractions by subtracting seconds from seconds and minutes from minutes, borrowing from the larger units when necessary.

Answer:

no solution

Step-by-step explanation:

lets isolate the absolute value first:

so

|x|-8+8=-2-8

|x|=-10

since absolute value cannot be less than -10, there is no solution.

Hope this helps!

The equation |x+8|=−2 has no solution because the absolute value of a number cannot be negative.

The equation |x+8|=−2 does not have a solution because the absolute value of a number is always non-negative, and it cannot equal a negative number. The absolute value represents the distance from zero on the number line, and distance cannot be negative. Thus, the equation |x+8|=−2 is inconsistent because it implies that a non-negative quantity (the absolute value) is equal to a negative number (−2), which is not possible.

When solving equations involving absolute values such as |x| = a, if 'a' is positive, then the solutions are x = a or x = -a, because both distances a and -a from zero have the same absolute value. However, if 'a' is negative, the equation has no solution, as the absolute value cannot take on negative values. If you encounter an absolute value equation set to a negative number, you can immediately conclude that there are no solutions.
