Answer:

(52.50x + 500) is greater or less than (60.50x + 300)

Step-by-step explanation:

Hope I answered your question!

The required inequality is given by 52.50x + 500 ≥ 60.50x + 300.

Given that,
Lola needs to rent a borrow for a formal event Heroes charges $52.50 per hour with a one-time rental fee of $500 by Ballroom T charges $60.50 per hour and a one-time fee of $300.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Let the number of hours be x,
According to the question,
so,
52.50x + 500 ≥ 60.50x + 300

Thus, the required inequality is given by 52.50x + 500 ≤ 60.50x + 300.

Since there's 34 lights and half of them are white and the other half are colored, half means 1/2 or divide by 2. We would do 34 divided by 2 and the answer is 17. There are 17 lights of each kind.

Have a great day!

Each of the TWO colors takes up half of the lights, meaning we can divide the amount of lights on the tree to get the quantity of lights per color.

34 divided by 2 is 17, so there are 17 lights of each kind on the tree.

Step-by-step explanation:

sorry if its wrong im just trying to help

Based on the scatterplot, The best prediction of the number of baseballs that will be used if 275 pitches are thrown will be 150. Option A is correct.

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

Given this information, the scatterplot below depicts the correlation between the number of baseballs used in 14 games and the number of pitches thrown in these games.

Making forecasts about the future is possible with a scatter plot. You can draw a line, referred to as a best-fit line, that is near the majority of the data points in order to aid in the forecasts. A line should be drawn with around half of the data points above and half below it.

Thus, based on the scatterplot, The best prediction of the number of baseballs that will be used if 275 pitches are thrown will be 150. Option A is correct.

Answer:

10

Step-by-step explanation:

Solve for p:

p - 7 = 3

Hint: | Isolate terms with p to the left hand side.

Add 7 to both sides:

p + (7 - 7) = 7 + 3

Hint: | Look for the difference of two identical terms.

7 - 7 = 0:

p = 3 + 7

Hint: | Evaluate 3 + 7.

3 + 7 = 10:

Answer: p = 10

Hey there!☺

[tex]Explanation:[/tex]

Solve for p | [tex]-7+p=3[/tex]

In step 1, we will simplify both sides of the equation:

[tex]p-7=3[/tex]

In step 2, we will add 7 to both sides:

[tex]p-7+7=3+7\\p=10[/tex]

p=10 is your answer.

Answer:

The probability of 213 or fewer cases of such cancer in a group of 479,908 people is 0.2776.

Step-by-step explanation:

We are given that assuming that cell phones have no​ effect, there is a 0.000462 probability of a person developing cancer of the brain or nervous system. We, therefore, expect about 222 cases of such cancer in a group of 479,908 people.

Let [tex]\hat p[/tex] = sample probability of a person developing cancer of the brain or nervous system.

The z-score probability distribution for the sample proportion is given by;

                            Z  =  [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]  ~ N(0,1)

where, p = population probability of a person developing cancer of the brain or nervous system = 0.000462

            n = sample of cell phone​ users = 479,908

Now, the probability of 213 or fewer cases of such cancer in a group of 479,908 people is given by = P([tex]\hat p[/tex] [tex]\leq[/tex] [tex]\frac{213}{479,908}[/tex] )

     P([tex]\hat p[/tex] [tex]\leq[/tex] 0.000444) = P([tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] [tex]\leq[/tex] [tex]\frac{0.000444-0.000462}{\sqrt{\frac{0.000444(1-0.000444)}{479,908} } }[/tex] ) = P(Z [tex]\leq[/tex] -0.59)

                                 = 1 - P(Z < 0.59) = 1 - 0.7224 = 0.2776

The above probability is calculated by looking at the value of x = 0.59 in the z table which has an area of 0.7224.

These results suggest about media reports that cell phones cause cancer of the brain or nervous​ system that there is around 28% chance that 213 or fewer cases of such cancer in a group of 479,908 people can take place.

Step-by-step explanation:

4 bunnies...... 10 hours

5 bunnies....... X hours

X=4 ×10 :5

X=40 :5

X=8 hours

[tex]12.5[/tex] hours

The unitary method is a methodology for solving problems that involves first determining the value of a single unit and then multiplying that value by the required value.

Time taken by [tex]4[/tex] bunnies to eat crops [tex]=10[/tex] hours

Time taken by [tex]1[/tex] bunny to eat crops [tex]=\frac{10}{4}[/tex] hours

Time taken by [tex]5[/tex] bunnies to eat crops [tex]=\frac{10}{4}\times 5[/tex]

                                                              [tex]=12.5[/tex] hours

So, [tex]5[/tex] bunnies eat the same crops in [tex]\boldsymbol{12.5}[/tex] hours.

Answer:

x = 1/2 or .5

Step-by-step explanation:

JK = 7x + 2, KL = 5x + 4 and JL = 12

JK + KL = JL

Plug in the equations for the Lines

7x + 2 + 5x + 4 = 12

Combine like-terms

12x + 2 + 4 = 12

12x + 6 = 12

Subtract 6 from either side

12x + 6 = 12

      -6      -6

12x = 6

Divide either side by 12

12x / 12 = 6/ 12

x= 1/2 or .5

Answer:

x=8

Step-by-step explanation:

3x-4=2x+4

Subtract 2x from each side using the subtraction property of equality

We want to get all the x 's on one side

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

x-4 = 4

Add 4 to each side using the addition property of equality

We want all the constants on one side

x-4+4= 4+4

x= 8

Answer:

x=8

Step-by-step explanation:

3x-4=2x+4

Subtract 2x on both sides

Your equation will look like

x-4=4

Add the four on both sides

Since x equals one you don't divide x

your answer will be x=8

Answer:

a

[tex]\% E = 0.9 \%[/tex]

b

[tex]\%E_1 = 10.1 \%[/tex]

Step-by-step explanation:

From the question we are told that

The probability that an employees suffered lost-time accidents last year is [tex]P(e) = 0.06[/tex]

The probability that an employees suffered lost-time accident during the current year is

[tex]P(c) = 0.05[/tex]

The probability that an employee will suffer lost time during the current year given that the employee suffered lost time last year is

[tex]P(c | e) = 0.15[/tex]

Generally the probability that an employee will experience lost time in both year is mathematically represented as

[tex]P(c \ n \ e) = P(e) * P(c \ |\ e)[/tex]

=> [tex]P(c \ n \ e) = 0.06* 0.15[/tex]

=> [tex]P(c \ n \ e) = 0.009[/tex]

Generally the percentage of employees that will experience lost time in both year is mathematically represented as

[tex]\% E = P(e \ n \ c ) * 100[/tex]

=> [tex]\% E = 0.009 * 100[/tex]

=> [tex]\% E = 0.9 \%[/tex]

Generally the probability that an employee will experience at least one lost time accident over the two-year period is mathematically represented as

[tex]P(e \ u \ c) = P(e) + P(c) - P(e \ n \ c)[/tex]

=> [tex]P(e \ u \ c) = 0.06 + 0.05 - 0.009[/tex]

=> [tex]P(e \ u \ c) = 0.101[/tex]

Generally the percentage of the employees who will suffer at least one lost-time accident over the two-year period is mathematically represented as

[tex]\%E_1 = P(e \ u \ c) * 100[/tex]

=> [tex]\%E_1 = 0.101* 100[/tex]

=> [tex]\%E_1 = 10.1 \%[/tex]

Answer:

B

Step-by-step explanation:

Non-essential expenses might not actually be needed so to save, you can reduce it or remove totally

The most effective method is B , such that determine a non-essential expense or any other expense, that can be reduced.

What are essential expenses and non- essential expenses ?

Non-essential expenses are often those that you don't necessarily require, while essential expenses are all living-related expenses.

It is given that you want to increase the amount of monthly savings in your budget.

Let's check which of the given option is most effective.

a. This option is not correct , because if essential expenses are fixed then there will be fixed expenses and so there can't be any increase in the savings.

b. This option is correct. Non - essential expenses are the expenses which are not necessary , so if we reduce these type of expenses then there may be increase in savings.

c. This option is not correct. There can't be any benefit if we are paying bills late , because if we need to pay tax on the bills with time , then we will have to pay more and hence no savings will be there.

d. This option is also not correct. Even if we are using the money from emergency savings , then there will be no increase in the savings rather it will get decrease.

Therefore , the most effective method is B , such that determine a non-essential expense or any other expense, that can be reduced.

4 - Maria

Step-by-step explanation:

Tim will not be in positions 1 or 4, as 1 and 4 represent the ends of the line.  Jenny cannot be in positions 1 or 4, as she is between two people.  Paco will not be in positions 2 or 4, as he is only in an odd numbered position. Maria will be in position 4, as none of the other three can be at position 4.  Paco will be in position 1, as Tim and Jenny cannot be at position 1.  The two positions left are 2 and 3. We'll assume that 1 represents the front of the line. Since Tim has to be in front of Jenny, he will take the position with the lower number, which is 2. This leaves Jenny with 3.
