Answer: [tex]m=\dfrac{-1}{3}, b=\dfrac{7}{3}[/tex]

Step-by-step explanation:

Given

Function is  [tex]f(x)=mx+b[/tex]

[tex]f(-2)=3[/tex]

[tex]\therefore 3=m(-2)+b\\\Rightarrow b-2m=3\quad \ldots(i)[/tex]

[tex]f(4)=1\\\therefore 1=4m+b\quad \ldots(ii)[/tex]

from (i) and (ii) we get

[tex]m=\dfrac{-1}{3}, b=\dfrac{7}{3}[/tex]

Answer:

$46.08

Step-by-step explanation:

Hi,

She gets 48 (1.35) when she sells 48 muffins. That equals 64.8.

But she pays 48 (.39) to make them. That equals 18.72.

64.8 - 18.72 = 46.08

She makes $46.08

Answer:

it is 36 inches

Step-by-step explanation:

Given:

[tex]f(x)[/tex] is continuous, [tex]f(3)=1,f(1)=6,f(6)=-2,f(-2)=3[/tex].

To find:

The value of [tex]\lim_{x\to 6^+}f(x)[/tex] and [tex]\lim_{x\to -2^-}f(x)[/tex].

Solution:

If a function f(x) is continuous at [tex]x=c[/tex], then

[tex]\lim_{x\to c^-}f(x)=f(c)=\lim_{x\to c^+}f(x)[/tex]

It is given that the function [tex]f(x)[/tex] is continuous. It means it is continuous for each value and the left-hand and right-hand limits are equal to the value of the function.

The function is continuous for 6. So,

[tex]\lim_{x\to 6^-}f(x)=f(6)=\lim_{x\to 6^+}f(x)[/tex]

[tex]\lim_{x\to 6^+}f(x)=f(6)[/tex]

[tex]\lim_{x\to 6^+}f(x)=-2[/tex]

The function is continuous for -2. So,

[tex]\lim_{x\to -2^-}f(x)=f(-2)=\lim_{x\to -2^+}f(x)[/tex]

[tex]\lim_{x\to -2^-}f(x)=f(-2)[/tex]

[tex]\lim_{x\to -2^-}f(x)=3[/tex]

Therefore, [tex]\lim_{x\to 6^+}f(x)=-2[/tex] and [tex]\lim_{x\to -2^-}f(x)=3[/tex].

Answer:

12 minutes

Step-by-step explanation:

The Hot tap fills 1/30th of the bath in 1 minute. The cold tap fills 1/20th of the bath in one minute. In one minute both taps together will fill (1/30 + 1/20) of the bath, which is 5/60ths or 1/12th of the bath. Since it takes one minute to fill 1/12th of the bath, it’ll take 12 minutes to fill the bath

117.8097 [tex]in^{2}[/tex]

Step-by-step explanation:

Depending on how you're math is going there are two ways to solve this,  find the are by the arc or just figure out the whole cookie and divide by 6.   Let's try the latter is seems easier to say.    I mean easier for me to say.  

area of a circle is pi * r^2

the diameter is 30 inches so the radius is half of that or 15 inches

then the whole cookie is

pi*15^2 = 706.858 [tex]in^{2}[/tex]

now divide by 6 or each piece

706.858 [tex]in^{2}[/tex] / 6 = 117.8097 [tex]in^{2}[/tex]

Answer:

the probability is 0.0750

Step-by-step explanation:

The computation of the probability is shown below;

The mean of x is

= 1.5 ÷ √79

= 0.1688

Now the probability is

= P(Z < -0.3 ÷ 0.1688) + P(\bar{x} > 0.3 ÷ 0.1688)

= P(Z < -1.78) + P(Z > 1.78)

= P(Z < -1.78) + 1 - P(Z < 1.78

= 0.0375 + 1 - 0.9625

= 0.0750

hence, the probability is 0.0750

Answer:

1) They are not inverses

2) They are inverses

Step-by-step explanation:

We need to find the composition function between these functions to verify if these functions are inverses. If f[g(x)] and g[f(x)] are equal to x they are inverses.

1)

Let's find f[g(x)] and simplify.

[tex]f[g(x)]=\frac{1}{2}g(x)+\frac{3}{2}[/tex]

[tex]f[g(x)]=\frac{1}{2}(4-\frac{3}{2}x)+\frac{3}{2}[/tex]    

[tex]f[g(x)]=\frac{7}{2}-\frac{3}{4}x[/tex]

As f[g(x)] is not equal to x, these functions are not inverses.

2)

Let's find f[g(x)] and simplify.

[tex]f[g(n)]=\frac{-16+(4n+16)}{4}[/tex]

[tex]f[g(n)]=\frac{-16+4n+16}{4}[/tex]

[tex]f[g(n)]=\frac{4n}{4}[/tex]

[tex]f[g(n)]=n[/tex]

Now, we need to find the other composition function g[f(x)]

Let's find g[f(x)] and simplify.

[tex]g[f(x)]=4(\frac{-16+n}{4})+16[/tex]

[tex]g[f(x)]=-16+n+16[/tex]

[tex]g[f(x)]=n[/tex]

Therefore, as f[g(n)] = g[f(n)] = n, both functions are inverses.

Answer:

$340

Step-by-step explanation:

Given data

Inititial fee= $100

cost per minute= $1

Let the total charge for x minutes by y

Hence the expression for the total charges after x minutes is

y= 100+1x

y=100+x

But an after is from 12pm - 4pm= 4 hours

x=4*60

x=240minutes

y=100+240

y=$340

Answer:

-1.833 ; we do not reject the Null.

Pvalue = 0.0409 ; We do not reject the Null

There is no significant evidence to conclude that the number of ounces contained in the cereal boxes is less than 13

Step-by-step explanation:

H0 : μ = 13

HA : μ < 13

Test statistic :

(xbar - μ) ÷ s/sqrt(n)

(12.8 - 13) ÷ 0.5/sqrt(21)

-0.2 / 0.1091089

= - 1.833

The critical value at α = 0.01 ; df = 21 - 1 = 20 = 2.528

-1.833 > - 2. 528 (left tailed test) ; Hence we do not reject the Null.

Test statistic :

Pvalue from Test statistic at DF = 20 ; α = 0.01

Pvalue = 0.0409

Pvalue > α

0.0409 > 0.01 ; Hence, we do not reject H0.

There is no significant evidence to conclude that the number of ounces contained in the cereal boxes is less than 13

Answer:  5x>20

Step-by-step explanation:   his budget is 20 so it will not be with the 5. Since each pack cost 5 dollars, it would 5x. Furthermore, the inequality symbol would be facing toward the 5 because dave went past his limit.

The inequality that represents he went over his $20 budget is 5x > 20.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, Dave went to a game convention to buy packs of trading cards.

Each pack cost $5. To get all of the cards he wanted, he went over his $20 budget.

As he went over his budget the inequality that represents this situation is,

5x > 20.
