Answer:

The equation is 18h=378

h=21

Step-by-step explanation:

So first you have to set up the equation

so if she makes 18 dollars an hour the first part of the equation would be 18h

She made 378 dollars in one week so now the equation is 18h=378

The answer is h=21 because 378/18 is 21

Answer: i think it is (5,6) if it is wrong sorry

Don't for get to drop a heart

Step-by-step explanation:

Answer:

For the first question, No, because there is 2 inputs and only 1 output so it is not a function.

Convince me: This does help you find whether it is a function or not. Since 24 has two outputs, it is not a function.

Step-by-step explanation:

Convice me explain: The reason is that is for a function to be a function, there must be one input for one output, it can't have two different outputs.

Hence, it is not a function because one input should have one output not more than you.

What is the ordered pairs?

An ordered pair [tex](a, b)[/tex] is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair [tex](a, b)[/tex] is different from the ordered pair [tex](b, a)[/tex] unless [tex]a = b[/tex].

(A) No, because there is only two inputs and which have only one output so it is not a function.

Convince me: It does help to you find whether it is a function or not. Since [tex]24[/tex] has two outputs,so it is not a function. So, one input have only one ouput not more than one.

Here given that,

Answer:18

Step-by-step explanation: 19-7=12 bolts and 7+7=14 so 12-14=18

If a sample of 7 bolts is selected, then the probability that all in the sample are defective = [tex]\frac{7}{50388}[/tex]

If a sample of 7 bolts is selected, then the probability that none in the sample are defective = [tex]\frac{66}{4199}[/tex]

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

For given question,

Out of 19 bolts, 7 bolts are defective.

So 19 - 7 = 12 bolts are non-defective.

If sample of 7 bolts is selected.

The total number of ways of selecting 7 bolts from the 19 bolts.

Using combination formula,

[tex]^{19}C_7\\\\=\frac{19!}{7!(19-7)!} \\\\=50388[/tex]

Let event A:  all bolts in the sample are defective

n(A) = 7

So the probability that all in the sample are defective would be,

[tex]P(A)=\frac{7}{50388}[/tex]

Let event B: no bolt in the sample are defective

This means the sample of 7 bolts has non-defective.

The total number of ways of selecting 7 bolts from the 12 non-defective bolts.

Using combination formula,

[tex]^{12}C_7\\=\frac{12!}{7!(12-7)!}\\\\ =792[/tex]

son n(B) = 792

So, the probability that none in the sample are defective would be,

[tex]P(B)=\frac{792}{50388} \\\\P(B)=\frac{66}{4199}[/tex]

Therefore,  If a sample of 7 bolts is selected, then the probability that all bolts in the sample are defective = [tex]\frac{7}{50388}[/tex]

If a sample of 7 bolts is selected, then the probability that none in the sample are defective = [tex]\frac{66}{4199}[/tex]

Answer:

16 hours

Step-by-step explanation:

Given

[tex]Initial = -124[/tex]

[tex]Rate = 8[/tex] per hour

Required

Determine the number of hours it gets to 4 degrees

Let the temperature at every hour, h be T.

So, we have:

[tex]T = Initial + Rate * h[/tex]

[tex]T = -124+ 8* h[/tex]

[tex]T = -124+ 8h[/tex]

To calculate the time it gets to 4 degrees. We first substitute 4 for T; then solve for h

[tex]4 = -124+ 8h[/tex]

Collect Like Terms

[tex]8h = 4 + 124[/tex]

[tex]8h = 128[/tex]

Solve for h

[tex]h = \frac{128}{8}[/tex]

[tex]h = 16[/tex]

Answer:

Step-by-step explanation:

cause there is 11 of 20

Answer:

7 Cows and 8 Chickens

Step-by-step explanation:

Note that cows have four legs each and chickens have two legs each.

if there were only cows, then 15 cows times 4 legs for each cow would give 15 x 4 = 60 legs. 60 is greater than 44, so some (maybe all) of the animals are chickens.

If there were only chickens, then 15 chickens times 2 legs for each chicken would give 15 x 2 = 30 legs. 30 is less than 44, so we have confirmed that there is a mixture of both cows and chickens on the farm.

One approach would be to build a table of possibilities:

Total legs will equal number of cows times 4 plus number or chickens times 2 and we know the total number of animals is 15, so we keep cows plus chickens equal to 15 and just keep adding a cow and subtracting a chicken and do the math until.we get 44 legs. We know that it will take less than 13 tries, since we already ruled out 15 cows or 15 chickens. We'll start with 1 cow and 14 chickens and go from there

1 Cow + 14 Chickens = (1 x 4) + (14 x 2) = 4 + 28 = 32 legs

2 Cows + 13 Chickens = (2 x 4) + (13 x 2) = 8 + 26 = 34 legs

3 Cows + 12 Chickens = (3 x 4) + (12 x 2) = 12 + 24 = 36 legs

4 Cows + 11 Chickens = (4 x 4) + (11 x 2) = 16 + 22 = 38 legs

5 Cows + 10 Chickens = (5 x 4) + (10 x 2) = 20 + 20 = 40 legs

6 Cows + 9 Chickens = (6 x 4) + (9 x 2) = 24 + 18 = 42 legs

7 Cows + 8 Chickens = (7 x 4) + (8 x 2) = 28 + 16 = 44 legs

We can stop here because we can see that 7 Cows and 8 Chickens have a total of 44 legs.

Another way to approach this is to use algebra and to make is shorter to write we can assign a variable to each item and relate them in some way.

Let's use the letter x to stand for cows and the letter y to stand for chickens so we don't have to keep writing chickens and cows. x and y are just common letters to use, by the way, could use w and k perhaps since cow has a w and chicken has a k...sadly they both start with c, so we can't use that for both.

We know a couple different, but related, things.

One thing we know is that the total number of animals is 15. We can write that as:

x + y = 15

That means cows (x) plus chickens (y) equals 15.

A second thing we know is that the total number of legs is 44. We can write that as

4x + 2y = 44

That means 4 times x (cow) plus 2 times y (chicken) is equal to 44 since each cow has 4 legs and each chicken has 2 legs.

Since we now have two related equations and two variables we can solve for the variables.

If we take the first equation and rearrange it, by subtracting x from both sides, we can see that one way to do it is the following

y = 15 - x

That means the number of chickens (y) is equal to 15 minus the number of cows (x). As long as we do the same thing on both sides of the equals sign the equation is still.equal...you will see this again below.

Now we can then substitute 15 - x for y in the second equation and then all we have is x in that equation. (We can do this because y is equal to 15 minus x...they both have the same value and mean the same thing...they are equal to each other)

4x + 2(15 - x) = 44

As you can see, we now have 2 times 15 minus x where we had 2 times y before. If we multiply the 2 through we get because 2 times 15 is 30 and 2 times x is 2x

4x + 30 - 2x = 44

We can subtract the 2x from 4x and we get

2x + 30 = 44

Now we can subtract 30 from both sides of the equation because as long as we do the same thing on both sides of the equals sign the equality holds true

2x + 30 - 30 = 44 - 30

30 minus 30 is zero and 44 minus 30 is 14 so now we have

2x = 14

If we divide both sides by two, we still maintain the equality and we get x on one side as 2x divided by 2 is 1x or just x and we get 7 on the other side as 14 divided by 2 is 7

x = 7

That means we have 7 Cows as x represents cows, so half the problem solved

If we now go back to our first equation,

x + y = 15

We can replace x with 7 and get

7 + y = 15

We can subtract 7 from both sides and maintain the equality and isolate y

7 - 7 + y = 15 - 7

Again, 7 minus 7 is zero so we have isolated y and 15 minus 7 is 8

y = 8

This means we have 8 Chickens since y represents chickens

Once again we have shown that Old MacDonald has 7 Cows and 8 Chickens

Answer/Steps to answer: (x= -10)

1. Simplify  1/2(x-106) to x-106/2.

x-106/2=12 + 7x

2. Multiply both sides by 2.

x−106=24+14x

3. Subtract x from both sides.

−106=24+14x−x

4. Simplify  24+14x-x to  24+13x.

-106=24+13x

5. Subtract 24 from both sides.

-106-24=13x

6. Simplify  -106-24 to −130.

-130=13x

7. Divide both sides by 13.

130/13=x

Ratio of two numbers = 2:3

The larger number = 6

Let the smaller number be x.

Which means :

[tex] =\tt 2 : 3 \: = \: x : 6[/tex]

[tex] = \tt \frac{2}{3} = \frac{x}{6} [/tex]

[tex] =\tt 2 \times 6 = 3 \times x[/tex]

[tex] =\tt 12 = 3x[/tex]

[tex] =\tt x = \frac{12}{3} [/tex]

[tex]\hookrightarrow\color{plum}\tt \: x = 4[/tex]

▪︎Therefore, the smaller number = 4

36 compared to 6 = [tex] \tt \frac{36}{6} [/tex]

Let the number be x.

Which means :

[tex] = \tt \frac{36}{6} = \frac{x}{3} [/tex]

[tex] =\tt \frac{36 \div 2}{6 \div 2} = \frac{x}{3} [/tex]

[tex] =\tt \frac{36}{6} = \frac{18}{3} [/tex]

▪︎Therefore, the fractional number [tex] \tt \frac{18}{3} [/tex] is equal to [tex] \tt \frac{36}{6} [/tex].

Number of Rose's for 24 red Rose's = 6

This can be written in a ratio as 24:6

Number of roses = 8

Let the number of red roses for these roses be x.

Which means :

[tex] =\tt \frac{24}{6} = \frac{x}{8} [/tex]

[tex] =\tt 24 \times 8 = 6 \times x[/tex]

[tex] =\tt 192 = 6x[/tex]

[tex] =\tt x = \frac{192}{6} [/tex]

[tex]\hookrightarrow \color{plum}\tt x = 32[/tex]

▪︎Therefore, 32 red roses are there if there are 8 roses.

Number of children for 2 adults = 7

This can be written in a ratio as 7:2

Number of children in the plaza = 21

Let the number of adults be x.

Which means :

[tex] = \tt \frac{7}{2} = \frac{21}{x} [/tex]

[tex] =\tt7 \times x = 2 \times 21 [/tex]

[tex] =\tt 7x = 42[/tex]

[tex] =\tt x = \frac{42}{7} [/tex]

[tex] \hookrightarrow \color{plum}\tt \: x = 6[/tex]

▪︎Therefore, 6 adults were there in the plaza.

Cost of 12 pencils = P60

Cost of 1 pencil :

[tex] = \tt \frac{60}{12} [/tex]

Thus, the cost of one pencil = P5

Cost of 25 pencils :

= Cost of one pencil × 25

[tex] =\tt 5 \times 25[/tex]

[tex] \color{plum}=\tt \: P \: 125[/tex]

▪︎Therefore, the cost of 25 pencils = P125

Step-by-step explanation:

Answer:

1/2925 = 0.0003 = 0.03% probability that you, Rebecca, and John are chosen.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the people are chosen is not important, so the combinations formula is used to solve the question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Desired outcomes:

Only 1 outcome in which these 3 people are selected, so [tex]D = 1[/tex]

Total outcomes:

3 people from a set of 27, so

[tex]T = C_{27,3} = \frac{27!}{3!(27-3)!} = 2925[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{1}{2925} = 0.0003[/tex]

1/2925 = 0.0003 = 0.03% probability that you, Rebecca, and John are chosen.
