She need to work a total of 6 hours of being a hostess because if she just works 5, she will not get the total $150 she needs to earn. I took this test and I got it correct.

The inequality that represents the number of hours Lynn needs to work both as a hostess and babysitting in order to earn at least $150 in a week is 7.5h + 10b ≥ 150. Here 'h' is the number of hours Lynn works as a hostess and 'b' is the number of hours she babysits.

To solve this mathematics problem, you need to set up an inequality. Lynn works at the restaurant earning $7.50 per hour (represented by 'h') and babysits earning $10 per hour (represented by 'b'). Given that she needs to make at least $150 in one week, the expression of her earnings from both jobs must be greater than or equal to 150. Hence the inequality will be 7.5h + 10b ≥ 150.

The coefficient of 'h' represents the wage rate Lynn earns per hour working as a hostess and 'b' is the number of hours she babysits. The sum of her earnings from both jobs is her total income. This sum must be at least $150, hence the 'greater than or equal to' sign.

Large number and small number are 44 and 17

Given:

Sum of two number = 61

Find:

Both numbers

Assume;

Small number = a

Large number = 3a - 7

Computation:

a + 3a - 7 = 61

4a - 7 = 61

4a = 61 + 7

4a = 68

a = 68 / 4

a = 17

So,

Small number = 17

Large number = 3a - 7

Large number = 3(17) - 7

Large number = 51 - 7

Large number = 44

Answer:

First answer

number of cats = 2

number of hamsters = 4

number of birds = 8

number of fishes = 1

Second answer

number of cats = 3

number of hamster = 6

number of  birds   =2

number of fishes =  4

Step-by-step explanation:

Let the number of cats be x . Let number of birds be y and Let number of fishes be z.

number of hamsters = 2 number of cats

                                    =2x

birds +cats + hamsters + fish = 15

 y +x +2x + z  = 15  

y +3x + z =  15

then number of hamsters = 2x

birds has legs = 2

hamster legs = 4

cats legs = 4

total legs  =40

2y+4x+4(2x) =40

2y+12x = 40

y+6x = 20   ,Since x ,y z are natural number   ,since x ,y and z are numbers of pets of each kind which have to be natural number ,therefore

Case 1 for y = 2   x = 3

for y = 8  x = 2

for y = 2 and x =3 ,we have

2+3(3) +z = 15

2+9+z = 15

11 +z = 15

 z = 15 -11 = 4

Case 2

for y= 8 and x=2 ,we have

8 +3(2) + z = 15

8 +6 +z = 15

   z =15-14 = 1

We have two answers for this problem

First answer

number of cats = 2

number of hamsters = 4

number of birds = 8

number of fishes = 1

Second answer

number of cats = 3

number of hamster = 6

number of  birds   =2

number of fishes =  4

For case 1   fish % =   [tex]\frac{1}{15} x100[/tex]=6.67 %

For case 2  fish =   [tex]\frac{3}{15} X100=20%[/tex]

Tina has 3 cats, 6 hamsters, 8 birds, and 0 fish, therefore 20% of her pets are cats.

First, let's denote the number of cats as 'x'. According to the question, the number of hamsters, which have twice as many as cats, is '2x'. Every cat and hamster has 4 legs. So the total number of legs from cats and hamsters is 4x (from cats) + 8x (from hamsters) = 12x. We know that the total number of legs is 40, so we can solve the equation 12x=40, therefore 'x', the number of cats, is approximately 3, making hamsters 6 (2x). This adds up to 9 pets, leaving us with 15 - 9 = 6 birds and fish. Since birds and fish have two legs and zero legs, respectively, the last 16 legs must belong to birds. That leaves the remaining pets (6-8=0) as fish.

As for the percentage of Tina's pets that are cats, we use the formula for finding a percentage:  (number of cats / total number of pets) * 100. So, (3 / 15) * 100 = 20%. Therefore, "20% of Tina's pets are cats".

Answer:

No, the two events "being in high school" and "GPA above 3.0" are not independent.

Step-by-step explanation:

If two events A,B are independent [tex]P(A|B)=P(A)[/tex]

P(high school | above 3.0) = [tex]\frac{14}{40}=0.35[/tex]

P(high school) = [tex]\frac{60}{100}=0.6[/tex]                                                                                                

So,0.35 ≠ 0.6

Since P(high school | above 3.0) ≠ P(high school), the events "being in high school" and "GPA above 3.0" are not independent.

The proportion of high school students with a GPA above 3.0 differs from the proportion of college students with a GPA above 3.0. Therefore, the events 'being in high school' and 'GPA above 3.0' are not independent according to the data provided.

To determine if "being in high school" and "GPA above 3.0" are independent events, we can check if the proportion of high school students with a GPA above 3.0 is the same as the proportion for college students. If the events are independent, the proportions should be equal.

From the two-way frequency table provided, we can calculate the proportions. There are 60 high school students and 40 college students. Among these, 14 high school students and 26 college students have a GPA above 3.0.

The proportion of high school students with a GPA above 3.0 is 14 out of 60, which simplifies to about 0.233.

The proportion of college students with a GPA above 3.0 is 26 out of 40, which simplifies to about 0.650.

Because these proportions are not equal, we can conclude that the events are not independent. Being in high school appears to have an impact on whether a student has a GPA above 3.0, based on this data set.

Therefore, the events 'being in high school' and 'GPA above 3.0' are not independent according to the data provided.

Answer:

The answer is B [tex]4^{6}[/tex].

Step-by-step explanation:

The number of horses is given by the expression;

[tex](4^{2} )^{3} *4^{0}[/tex]

First we can simplify the value to the left of the multiplication,

[tex](4^{2} )^{3}[/tex]

This is a indices multiplication so we can rewrite this as,

[tex]4^{6}[/tex]

Now we can look at the value that is to the right of the multiplication.

[tex]4^{0}[/tex]

If you take any number that is not 0 and it's index is 0 the value of that number will be one.

Therefore, [tex]4^{0}[/tex] = 1

Now we can write the full expression as;

[tex](4^{2} )^{3} *1[/tex]

=[tex](4^{2} )^{3}[/tex]

=[tex]4^{6}[/tex]

Therefore the answer is B [tex]4^{6}[/tex].

We know that the perimeter of a rectangle is twice the length, plus twice the width.  

P = 2L + 2W  

We also know that the perimeter is 156.  

P = 156  

Finally, we know that the width is 12 less than the length.  

W = L - 12.  

The next thing that we do is substitute the information that we have into the original equation:  

P = 2L + 2W  

156 = 2L + 2(L - 12)  

From this point we start to solve  

156 = 2L + 2L - 24 <---we multiplied the '2' through the parenthesis  

156 + 24 = 2L + 2L - 24 + 24  

180 = 2L + 2L <--- getting like terms on same sides  

180 = 4L <---combining like terms  

180/4 = 4L/4 <--- getting like terms on same sides  

45 = L <---now we have a value for L  

Now we take the known value for L and substitute it in to our equation for W  

W = L - 12  

W = 45 - 12  

W = 33  

So now we have Length = 45 and Width = 33.

w = l - 12

156 = 2l + 2w

Since we have a value of w, we can plug that into the variable w to find the exact value of l.

156 = 2l + 2(l - 12)

Distributive property.

156 = 2l + 2l - 24

Combine like terms.

156 = 4l - 24

Add 24 to both sides.

180 = 4l

Divide both sides by 4.

l = 45

Now that we have the exact value of l, we can find the exact value of w.

w = l - 12

w = 45 - 12

w = 33

We now know the width is equal to 33 cm, and the length is equal to 45 cm. (This is your answer.)

We can verify by plugging these values into the second equation.

156 = 2l + 2w

156 = 2(45) + 2(33)

156 = 90 + 66

156 = 156 √ this is correct.

You will have 2 piano lessons and 6 tuba lessons

To solve this, we find the least common multiple (LCM) of 7 and 3, which is 21. Not counting the initial or ending day, there are 19 days in between, during which time 2 piano lessons and 6 tuba lessons occur.

The key concept in this question is the Least Common Multiple (LCM) of two numbers. Given that you have piano lessons every 7 days and tuba lessons every 3 days, we are seeking to find out when these cycles will align again. The LCM of 7 and 3 is 21, meaning that you will have both lessons on the same day every 21 days.

Not counting today or that next joint lesson day (a total of 21 days), we then have 19 days remaining. For piano lessons, since they occur every 7 days, you will have 19 / 7 = 2 piano lessons in between, with some non-whole number of days leftover. Similarly, you will have 19 / 3 = 6 tuba lessons in between, again with a non-whole number of days leftover. Therefore, the answer is 2 piano lessons and 6 tuba lessons.
