The equation which satisfied the given expression after simplification are (a) 3x = 24 and (c) 3(x - 2) = 18.

How simplification method work?

In mathematics, the simplification method is used for the equation formation for the problem statements. And it also convert the complicated expression into simpler one to make the calculation easy.

According to the question, the given equation can be simplified by using simplification method and it is written below:

The given equation is: 3x - 6 = 18

3x = 18 + 6 = 24 ⇒ 3x = 24

Similarly, 3x - 6 = 18

3(x - 2) = 18

Hence, the equation which satisfied the given expression after simplification are (a) 3x = 24 and (c) 3(x - 2) = 18.

The distance between the lake and campground  is 48 miles.

Given

The distance between the campground and the entrance is 2

The actual distance between them is 8 miles

Hence the scale is 2 for 8 miles

Also, Distance on the map between campground and lake is 12 inch.

Let us say actual distance is x

There fore we can form equation as

2x = 12x18

2x = 216

x=48

Hence the actual distance between campground and lake is 48 miles.

Using vertical angles, it is found that:

A. The solution for y is of y = 4.

B. The angle measures are given as follows:

If two angles are opposite by the same vertex in crossing segments, these angles are called vertical angles, and they are congruent, that is, they have the same measure.

In the context of this problem, the angles of 6y + 42 and of 66 are vertical, hence the value of y is calculated as follows:

6y + 42 = 66

6y = 24

y = 24/6

y = 4.

Angles A and C are supplementary, meaning that the sum of their measures is of 180º, hence:

<C + 66º = 180º

<C = 180º - 66º

<C = 114º.

Angles C and D are vertical, hence the measure of angle D is calculated as follows:

<D = 114º.

Answer: f(3) = 0.84375

Step-by-step explanation:

f(3) is asking for the value of the function when x = 3, not multiplying f by 3. (f(x) is basically the output, y)

So we just plug in 3 for x and simplify (use PEMDAS)

f(3) = 2(0.75)^3

f(3) = 2(0.421875)

f(3) = 0.84375

Answer:

[tex]\frac{27}{32}[/tex]

Step-by-step explanation:

It may be a bit easier to represent 0.75 as a fraction, since we can use the following property of exponents: [tex](\frac{a}{b})^x = \frac{a^x}{b^x}[/tex]

We can represent 0.75 as: [tex]\frac{3}{4}[/tex]

And substituting this into the function we get: [tex]f(x)=2(\frac{3}{4})^x[/tex]

calculating the value when x=3, we get: [tex]f(3)=2(\frac{3}{4})^3[/tex]

using the property previously stated we get: [tex]f(3)=2(\frac{3^3}{4^3})[/tex]

Raising each value to the exponent we get: [tex]f(3)=2(\frac{27}{64})[/tex]

When we multiply by two, we can simplify by splitting up 64, into two factors: 2 and 32, to get: [tex]\frac{2*27}{32*2}[/tex]

From here it's easy to see that we can cancel out the values 2, to get: [tex]\frac{27}{32}[/tex]

The percentage of players serves were between 115 mph and 145 mph is approximately 16%.

Given :

The statistician reported that the mean serve speed was 100 miles per hour

the standard deviation of the serve speeds was 15 mph

Assume that the statistician also gave us the information that the distribution of serve speeds was mound-shaped and symmetric

To find :

What percentage of the player's serves were between 115 mph and 145 mph?

Solution :

μ =100

σ = 15

P ( 115 < x <145)

= P ( [tex]\frac{115-100}{15}[/tex] <  x-μ /6 <[tex]\frac{145-100}{15}[/tex] )

= P ( [tex]\frac{15}{15}[/tex] < z < [tex]\frac{15}{15}[/tex] )

= p ( 1<z<3)

= p( z<3)-p(z-1)

=0.9987-0.8413

=0.1574

p ( 115<xx<145)= 15.74 %

p( 115<x<145)= approximately 16%

The percentage of players serves were between 115 mph and 145 mph is approximately 16%.

Answer:

option d is the correct answer

The probability that rose identifies all 3 cards in the correct order is 1/132,600 by the concept of permutation.

It is the separate arrangements of a given number of associates taken all at once, or some of them, or just a few of them. There are two possible meanings, AB and BA, for instance, if we have the two elements A and B.

Following the arrangement of 'r' items from a total of 'n' elements, the number of permutations is,

nPr = n! / (n – r)!

Here to obtain the probability in correct order use permutation formula

Recall that, Probability is calculated as favorable outcomes divided by all possible outcomes.

Favorable number of outcomes = 1 (as only one order is correct)

Total outcomes = 52p3 (since 3 cards to be arranged from pack of 52)

So, the probability of rose identifies all 3 cards in correct order =1/52p3

Probability = [tex]\frac{1}{52!/(52-3)!}[/tex]

Probability = 49! /52!

Probability = 49! /52*51*50*49!

Probability = 1/52*51*50

Probability = 1/132,600

Therefore, the probability that rose identifies all 3 cards in the correct order is 1/132,600.

The ratio between cups of beans and cups of rice is 10/13 . Option C

A ratio can described as an ordered pair of numbers, like y and z, that is written mathematically in the form y / z where the denominator of the fraction is not equal to zero.

It is known to describe the number of times an element or number contains another number proportionally.

It is also seen as the comparison of two quantities, elements or numbers that has the same units and likewise, explains how much one of the elements or quantity is found in the another one.

This is done based on their sizes or magnitudes.

A proportion is a mathematical equation with two ratios set equivalent or equal to each other.

Given that;

Beans = 2 1/ 2 cups

Rice = 3 1/4 cups

Convert to mixed fractions;

Beans = 5/2

Rice = 13/4

Now, divide the cups of beans by that of rice;

= 5/ 2 ÷ 13/4

= 5/2 × 4/13

= 10/13
