Answer:

How far does Clare travel in one hour?

A: 36

How far does Clare travel in three hours?

A: 108

How far does Clare travel in 3.5 hours?

A: 126

Step-by-step explanation:

Find the Unit Value

72/2 = 36

Clare travels 36 miles per hour

Therefore, you must multiply the hours by the Unit travel time for the answers.

1 X 36 = 36

3 X 36 = 108

3.5 X 36 = 126

Answer:

The slope is 1

Step-by-step explanation:

Slope is the steepness of a line and so what I do is i use y/x or rise over run

so for the x it goes up one and so is with the y

y/x = 1/1= 1

So your slope is 1!

Hope this helped :D

Answer:

1

Step-by-step explanation:

We find the slope by using the formula y-y1 over x-x1. so to find the slope in this problem we need to choose two points and use the formula. When I solved it I chose points (0,1) and (1,2). When we plug these values into the formula we get 2-1/1-0. 2-1 is 1 and 1-0 is 1. 1/1 simplifies to 1.

Answer:

26.26

Step-by-step explanation:

1. First, multiply 6.59 by 2 since your looking for 2 pounds of strawberries. Answer = 13.18

2. Second, multiply 3.27 by 4 since your looking for 4 pounds of strawberries. Answer = 13.08

3. Last but not least, add both of the answers together. Answer to whole question = 26.26 pounds of strawberries and watermelons

Here's what we're given:

1 lb strawberries = $6.59 (where the cost equals price × lb)

1 lb watermelon = $3.27 (where the cost equals price × lb)

c = combined cost (this is what we're looking for)

c = cost of strawberries + cost of watermelons

Going by the definition of strawberries' and watermelons' costs (cost is price times pounds), replace with variables.

c = (2 × $6.59) + (4 × $3.27)

c = 13.18 + 13.08

c = 26.26

c = $26.26

Answer:

The sample size is  [tex]n = 384 [/tex]  

Step-by-step explanation:

From the question we are told that

     The margin of error is [tex]E = 0.05[/tex]

Here we will assume that the sample proportion is  [tex]\^ p = 0.5[/tex]

 From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=> [tex]n = [\frac{1.96 }{0.05} ]^2 * 0.5 (1 - 0.5  ) [/tex]        

=> [tex]n = 384 [/tex]    

Answer:

y= -4x - 3

Step-by-step explanation:

the Y intercept is -3 and your slope is -4

the reason you are subtracting instead of adding is because the line is going down which means it is negative.

The expression that represents the phrase. B.) 42 - 12

Answer:42-12

Step-by-step explanation:

Answer:

Cost of one pound of walnuts = x = $1.5

Cost of one pound of Chocolate chip = y =$3.75

Step-by-step explanation:

Let:

Cost of one pound of walnuts = x

Cost of one pound of Chocolate chip = y

Now making equations from the statements.

For 3 pounds of walnuts and 2 pounds chocolate Chips,the cost is $12: [tex]3x+2y=12[/tex]

For 5 pounds of walnuts and 6 pounds of chocolate chips the total cost is $30: [tex]5x+6y=30[/tex]

We need to solve these equations to find values of x and y

Let:

[tex]3x+2y=12--eq(1)\\5x+6y=30--eq(2)[/tex]

Multiply eq(1) by 3 and subtract both equations

[tex]9x+6y=36\\5x+6y=30\\- \ \ \ - \ \ \ \ -\\-------\\4x=6\\x=\frac{6}{4}\\x=1.5[/tex]

Now, finding value of y bu putting value of x, x= 1.5 in eq(1)

[tex]3x+2y=12\\3(1.5)+2y=12\\4.5+2y=12\\2y=12-4.5\\2y=7.5\\y=\frac{7.5}{2}\\y=3.75[/tex]

So, we get value of y: y=3.75

Cost of one pound of walnuts = x = $1.5

Cost of one pound of Chocolate chip = y =$3.75

Answer:

AD = 15

Step-by-step explanation:

Based on the Pythagoras Theorem, the longest side of a right-angled triangle is: [tex]\sqrt{a^{2}+b^{2}}[/tex] where a and b are the legs of the triangle.

In triangle BDC, we can put in the formula to find BD.

85 = [tex]\sqrt{77^{2}+BD^{2}}[/tex]

85² = 77² + BD²

7225 = 5929 + BD²

BD² = 7225 - 5929

       = 1296

BD = [tex]\sqrt{1296}[/tex]

BD = 36

In triangle ABD, we can put in the formula to find AD.

39 = [tex]\sqrt{36^{2}+AD^{2}}[/tex]

39² = 36² + AD²

1521 = 1296 + AD²

AD² = 1521 - 1296

       = 225

AD = [tex]\sqrt{225}[/tex]

AD = 15

Answer:

Matt=25y, George =44y, Brad=30y

Step-by-step explanation:

Brad=B

Matt=M

George=G

Year=y

Then we have:

Matt=y

Brad is 5 years older than Matt⇒B=(M+5)y

George is 6 less than  twice Matt's age⇒G=(2M-6)y

The sum=B+G+M=(M+5)+(2M-6)+(M)=90

So we can get age of Matt (M) By:

(M+5)+(2M-6)+(M)=90

4M-1=99

4M=100  dividing by 4

M=25 ⇒ Matt=25y

G=(2M-6)y=(2*25)-6=44 ⇒ George =44y

B=(M+5)y=25+5=30y ⇒ Brad=30y

48/12=4

Answer:

12p = 48

Step-by-step explanation:

We already know Miguel has 48 photos already selected, with 12 pages to chose from. Since we want to figure out an equation for the number of photos  Miguel is going to put on each page, you would have to do this: we do know the number of pages Miguel has but we don't know how many photos per page. So, you would write 12p for the unknown number of photos per page. Since he already has 48 photos and the 48 will not be affected during this equation, the answer to the equation would equal 48. So, the final answer would be 12p = 48

Answer:

4720

Step-by-step explanation:

I can't show the pencil or paper :/

1180(4) = 4720

4720/4 = 1180

In a company, there are 5,900 workers can work.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

In a company, 80% of the workers are men.

And, 1,180 people work for the company who aren't men.

Let total workers in a company = x

So, we can formulate;

In a company, 80% of the workers are men.

⇒ 20% of workers are not men's.

Here, 1,180 people work for the company who aren't men.

Hence, We get;

⇒ 20% of x = 1180

⇒ 20 / 100 × x = 1180

⇒ 20x = 1180 × 100

⇒ x = 1180 × 5

⇒ x = 5900

For the second question, just plug in the x value and isolate the y value

Step-by-step explanation:

1. 9y=36-13x

y=4-13/9 x

4 is the y-intercept

Answer:

d and (- 4, 33 )

Step-by-step explanation:

Given

13x + 9y = 36

To find the y- intercept, substitute x = 0 into the equation and solve for y

13(0) + 9y = 36, that is

0 + 9y = 36

9y = 36 ( divide both sides by 9 )

y = 4 ← y- intercept

---------------------------------------------

Given

y = - 6x + 9 and (- 4, y) then substitute x = - 4 into the equation

y = - 6(- 4) + 9 = 24 + 9 = 33

Thus (- 4, 33 ) is the ordered pair

Answer:

b. False

Step-by-step explanation:

The binomial distribution model allows us to compute the probability of successes when the process is repeated a specific number of times.

The  binomial distribution model is given as;

[tex]P(X) = \frac{n_!}{x! (n-x)!} P^x (1-P)^{(n-x)}[/tex]

n is the number of times the process is repeated,

x is the  the number of successes,

p is the occurrence of the outcome of interest,

Thus, the probability of elapsed time is best determined with Exponential distribution.

Thus, the correct option is "b"

Step-by-step explanation:

For this problem you just need to find the distance between each of the x values and each of the y values.
