Answer:

4n=c

Step-by-step explanation:

your trying to figure out how how much he paid and how much money it cost total so you have to multiply the cost of one by the number of notebooks you have n and by doing that you would be able to get your total cost c

Answer:

The cost of n notebooks is 4n dollars.

Step-by-step explanation:

C(n) = 4n

Answer:

Complete question :

Find the standardized test statistic t for a sample with n = 15, x = 10, s = 0.8, H0: μ = 10.5. Round your answer to three decimal places.

Answer:

−2.420614

Step-by-step explanation:

Given that:

Given that:

n = 10

s = 0.8

X = 15

μ = 15.9

Using the relation :

(x - μ) / (s/√n)

(10 - 10.5) / (0.8/√15)

-0.9 / 0.2065591

= −2.420614

Hence, the standardized test statistic = −2.420614

Answer:

Step-by-step explanation:

Given the expression of the speed satisfying the equation |S-60|≤17.5

The inequality expression will return both a negative and positive value.

For the positive value of the function;

S-60 ≤17.5

S ≤17.5+60

S  ≤ 77.5

For the negative value of the function;

-(S-60) ≤17.5

-S+60 ≤17.5

-S  ≤17.5 -60

-S  ≤ -42.5

multiply through by -1

S≥42.5

Hence the minimum speed limit is S≥42.5 while the maximum is S  ≤ 77.5

Answer:

I can't make a table but it would be like year to inches of percipitation Like:

Year | Precipitation (Inches)

2015 | 44.83

2016 | 45.18

2017 | 47.87

2018 | 35.73

2019 | 33.88

For the relationship just determine the pattern if it is addition subtraction e.t.c

Ex. The relationship is +30 or -56

Last but not least determine if it is a function pretty simple

And for my effort please name me the brainliest I really need Thank u

Answer:

the answer is 2x-22

Step-by-step explanation:

Answer:

Step-by-step explanation:

4x = 6x - 44

4x - 6x = -44

-2x = -44

x = 44/2

x = 22

Answer:

It would be c!

Step-by-step explanation:

Answer:

y = x + 7

Step-by-step explanation:

The equation of a line in slope - intercept form is expressed as y = mx+c

m is the slope

c is the intercept

Get the slope m;

m = tan theta

m = tan 45

m = 1

Get the intercept c;

Substitute m = 1 and (-2, 5) into the equation y = mx+c and get c;

5 = 1(-2)+c

5 = -2+c

c = 5+2

c = 7

Get the required equation;

y = 1(x)+ 7

y = x + 7

Hence the equation of the line is y = x+7

yes

Answer:

[tex]x^3-10x^2+31x-28[/tex]

Step-by-step explanation:

Since we are looking for a polynomial with RATIONAL coefficients, then we know that if [tex]3-\sqrt{2}[/tex]  is a root, then its conjugate  [tex]3+\sqrt{2}[/tex] must also be a root

Therefore, we build the polynomial using binomial factors with the given roots as shown below:

[tex](x-4)*(x-3+\sqrt{2} )*(x-3-\sqrt{2} )= (x-4)((x-3)^2-2)=\\=(x-4)*(x^2-6x+9-2) =(x-4)*(x^2-6x+7)=\\=x^3-10x^2+31x-28[/tex]

Answer:

A bat

Step-by-step explanation:

Answer:

The bat flies faster by 7 feet

Step-by-step explanation:

first, you need to find some common ground. 84 and 4 can both be divided by two 84/2=42 so now we know that:

-The bat flies 42 feet in two seconds

-The dove flies 35 feet in two seconds

So we know that the bad flies faster because the number is greater, but by how much?

To find this just subtract 35 from 42 to get 7.

So to summarize

The bat flies faster by 7 feet

Answer/Step-by-step explanation:

3. Function: NO

Justification: there will be more than one y-value/output related to one x-value/input.

4. Function: YES

Justification: There are exactly one y-value/output related to each input/x-value in the relation.

5. Function: YES

Justification: each x-value/input is mapped to exactly one y-value/output. No input value is mapped to more than one output value.

Answer:

x = -47, y = 39

Step-by-step explanation:

2x+3y=23 →equation 1

3x+4y=15 →equation 2

by elimination method,

(2x+3y=23) × 4

(3x+4y=15) × 3

8x + 12y = 92

(-)      (-)       (-)

9x + 12y = 45

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

-1x + 0    = 47

-x = 47

x = -47

substitute x=-47 in equation 1

2(-47) + 3y = 23

-94 + 3y = 23

3y = 23 + 94

3y = 117

y = 117/3

y = 39

therefore, x = -47 and y = 39

Step-by-step explanation:

Answer:

The sample size is  [tex]n =  841 [/tex]

Step-by-step explanation:

From the question we are that

    The standard deviation is  [tex]\sigma = 5.6 \ hours[/tex]

     The margin of error is  [tex]E = 0.45[/tex]

From the question we are told the confidence level is  98% , hence the level of significance is    

      [tex]\alpha = (100 - 98) \%[/tex]

=>   [tex]\alpha = 0.02[/tex]

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

   [tex]Z_{\frac{\alpha }{2} } =  2.33[/tex]

Generally the sample size is mathematically represented as  

   [tex]n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2[/tex]

=>   [tex]n = [2.33 } *  5.6}{0.45} ] ^2[/tex]

=>   [tex]n =  841 [/tex]
