Room A: Cleaning fee: $50

Rate: $24 per hour

Room B: Cleaning fee: $80

Rate: $18 per hour

The band has $250 to spend. Let t be the time (in hours) the band rents the room.

a. Write and solve an inequality to represent the time (in hours) the band could rent room A.

b. Write and solve an inequality to represent the time (in hours) the band could rent room B

c. Which room should the band rent? Explain your answer.

**Answer:**

band could rent room B for a maximum of 9.44 hours.

**Step-by-step explanation:**

To represent the time (in hours) the band could rent room A, we need to consider both the cleaning fee and the hourly rate. The total cost of renting room A for t hours is given by the expression "50 + 24t". Since the band has $250 to spend, we can write an inequality to represent the maximum time they could rent the room:

50 + 24t <= 250

We can solve this inequality for t by subtracting 50 from both sides:

24t <= 200

Then, by dividing both sides by 24, we get:

t <= (200/24) hours

t <= 8.33 hours

So, the band could rent room A for a maximum of 8.33 hours.

b. To represent the time (in hours) the band could rent room B, we can use a similar approach as above. The total cost of renting room B for t hours is given by the expression "80 + 18t". Using the same budget of $250, we can write the following inequality:

80 + 18t <= 250

We can solve this inequality for t by subtracting 80 from both sides:

18t <= 170

Then, by dividing both sides by 18, we get:

t <= (170/18) hours

t <= 9.44 hours

So, the band could rent room B for a maximum of 9.44 hours.

c. From the above results, we can see that the band could rent room B for a slightly longer period of time compared to room A. However, the hourly rate for room B is cheaper than that of room A. So even though the band will get to use room B for a longer period of time, they will pay less overall to rent it. Additionally, the cleaning fee is cheaper in room B. Based on this information, the band should rent room B. They can stay in the room longer, pay less per hour, and pay less in cleaning fees.

Some biologists believe the evolution of handedness is linked to complex behaviors such as tool-use. Under this theory, handedness would be genetically passed on from parents to children. That is, left-handed parents would be more likely to have lefthanded children than right-handed parents. An alternate theory asserts that handedness should be random, with left- and right-handedness equally likely. In a recent study using a simple random sample of n ï€½ 76 right-handed parents, 50 of the children born were right-handed. ( pË† =0.658 .) Suppose handedness is a random occurrence with either hand equally likely to be dominant, implying that the probability of a right-handed offspring is p =0.50.

Required:

a. Show that it is reasonable to approximate the sampling distribution of pÌ‚ using a normal distribution.

b. Assuming left- and right-handed children are equally likely from right-handed parents, what is the probability of observing a sample proportion of at least pÌ‚ =0.658 ?

**Answer:**

**a) **Since both np >= 5 and n(1-p) >= 5, it is reasonable to approximate the sampling distribution of p^‚ using a normal distribution.

**b) **0.5 = 50% probability of observing a sample proportion of at 0.658.

**Step-by-step explanation:**

** a. Show that it is reasonable to approximate the sampling distribution of pÌ‚ using a normal distribution. **

We need that:

np >= 5

n(1-p) >= 5

**Sample of 76, 50 of the children were born were right-handed.**

So [tex]n = 76, p = \frac{50}{76} = 0.658[/tex]

np = 76*0.658 >= 5

n(1-p) = 76*0.342 >= 5

Since both np >= 5 and n(1-p) >= 5, it is reasonable to approximate the sampling distribution of p^‚ using a normal distribution.

**b. Assuming left- and right-handed children are equally likely from right-handed parents, what is the probability of observing a sample proportion of at least pÌ‚ =0.658 ?**

This is the mean, so 50% below and 50% above.

0.5 = 50% probability of observing a sample proportion of at 0.658.

Please please give answer , the numbers on the side are the options

Answer:

24 tiles (none of the options given is correct)

Step-by-step explanation:

Number of tiles required to floor the room = area of the room/area of 1 tile

Area of the room = 36m * 24m = 864 m²

Area of 1 tile = 6² = 36 m²

Number of times required = 864/36 = 24 tiles

Find the segment lengths

Answer:

y = 18

Step-by-step explanation:

[tex] \frac{21 + 7}{21} = \frac{y + 6}{y} [/tex]

[tex] \frac{28}{21} = \frac{y + 6}{y} [/tex]

Cross multiply

28*y = 21(y + 6)

28y = 21y + 126

28y - 21y = 126

O D. F(x) = -x"' +52° + 4

**Answer:**

The correct answer is A.

**Step-by-step explanation:**

From the picture you provided, you choose option A, f(x) = x^7 - x^3 - 3x^2 + 3 . Hope that helped :)

The **functions** that could have created this graph is f(x) = x⁷-x³-3x²+3

A **function** is an equation for which any x that can be put into the **equation** will produce **exactly one output **such as y out of the equation.

Given is a graph, we need to find its **equation**,

So, the graph is **U-shaped**, therefore, the leading coefficient is, a > 0

also, the **graph** does not have a zero at the origin,

The function which could possibly create the graph is the option; A.

F(x) = x⁷-x³-3x²+3

The leading coefficient is 1 > 0

The function has no factors of x = 0

The function has a **linear factor**.

Hence, the **functions** that could have created this graph is f(x) = x⁷-x³-3x²+3

**Step-by-step explanation:**

[tex] \frac{1}{2} + \frac{1}{4} \\ = ( \frac{1}{4} + \frac{1}{4} ) + \frac{1}{4} \\ = ( \frac{1}{8} + \frac{1}{8} ) + (\frac{1}{8} + \frac{1}{8} ) + (\frac{1}{8} + \frac{1}{8} ) \\ = ( \frac{2}{8} ) + ( \frac{2}{8} ) + ( \frac{2}{8} ) \\ = \frac{6}{8} \\ = \frac{2 \times 3}{2 \times 4} \\ = \frac{3}{4} [/tex]

The given **operation **of the two **fractions **can be found as 6/8. The correct option is (D).

A **fraction **is a number written in the form a / b, where a and b are integers and b ≠ 0.

The number a is called as the **numerator **and b is the **denominator**.

The given **expression **is 1/2 + 1/4.

It can be solved using the **strip **given as below,

The number of 1/8 sections under 1/2 in the strip is 4.

And, the number of 1/8 sections under 1/4 in the strip is 2.

Then, the addition of the two fractions is equivalent to the total number of 1/8 sections under both of them.

It can be written in mathematical form as,

A researcher wants to determine whether the number of minutes adults spend online per day is related to gender. A random sample of 315 adults was selected and the results are shown below. Find the expected frequency for the cell E2,2 to determine if there is enough evidence to conclude that the number of minutes spent online per day is related to gender. Round to the nearest tenth if necessary. Gender| 0-30| 30-60| 60-90| 90+ Male| 23|35|76|46 Female|31|42|46|16

**Answer:**

The expected frequency for the cell E2,2 is = 33

**Step-by-step explanation:**

The given data is

Gender | 0-30| 30-60| 60-90| 90+ Totals

Male | 23 | 35 | 76 | 46 180

Female | 31 | 42 | 46 | 16 135

Totals 54 77 122 62 315

The expected frequency for the cell E2,2 is :

Expected for the (30-60 box for females) = Total of (30-6)/ (total )* females

= ( 77/315)135= 33

Here p= 77/315 and n= 135

therefor X= pn = 33

χ²= (33-42)²/33= 2.455 ( for the single value of E2,2=33)

Expected for the (30-60 box for males) = Total of (30-6)/ (total )* males

= ( 77/315)180= 44

χ²= (44-42)²/44= 0.09

The critical region is χ² (0.05) 3 ≥ χ²= 11.34

Let the null and alternate hypothesis be

H0:the number of minutes spent online per day is not related to gender

against

Ha: the number of minutes spent online per day is related to gender

The single value of χ² for E2,2 = 2.45 is less than the critical value of 11.34.

5. The students in class usually drink a lot of water to help with their studies. I have found that

with five students in the class at least 30 litres of water is needed. How much water will be

needed when there are 30 students in the class?

**Answer:**

For s students, at least 6s liters of water will be needed. So, for 30 students, at least 6*30 = 180 liters of water will be needed.

**Step-by-step explanation:**

This question is solved by **proportions**, using rule of three.

**I am going to say that:**

s is the number of students.

l is the number of liters of water needed for s students.

**I have found that with five students in the class at least 30 litres of water is needed.**

This means that:

[tex]\frac{s}{l} = \frac{5}{30}[/tex]

[tex]5l = 30s[/tex]

[tex]l = \frac{30s}{5}[/tex]

[tex]l = 6s[/tex]

This means that for s students, at least 6s liters of water will be needed. So, for 30 students, at least 6*30 = 180 liters of water will be needed.
