Answer: 7 days

Step-by-step explanation: if he can make 12 liters in 6 days then you can divide 12 by 6 to know he can make 2 liters in 1 day. If he only needs 2 more liters, he only needs one more day and he has already spent 6 days and adding the one extra day, it would be 7 days

Answer:

4 x 2 x 1 = 28

Step-by-step explanation:

Answer:

[tex](a)\ Pr = \frac{2}{5}[/tex]

[tex](b)\ Pr = \frac{9}{20}[/tex]

[tex](c)\ E(Orange) = 100[/tex]

[tex](d)\ E(Orange) = 62.5[/tex]

Step-by-step explanation:

Solving (a): Theoretical probability of green or yellow

Here, we consider the spinner itself

From the attached image, we have:

[tex]n= 5[/tex] --- i.e. 5 sections

[tex]Yellow = 1[/tex]

[tex]Green = 1[/tex]

So, the probability is:

[tex]Pr = P(Yellow)\ or\ P(Green)[/tex]

[tex]Pr = \frac{Yellow}{n} + \frac{Green}{n}[/tex]

[tex]Pr = \frac{1}{5} + \frac{1}{5}[/tex]

Take LCM

[tex]Pr = \frac{1+1}{5}[/tex]

[tex]Pr = \frac{2}{5}[/tex]

Solving (b): Experimental probability of green or yellow

Here, we consider the result of the experiment

From the attached image, we have:

[tex]n= 40[/tex] --- i.e. 40 spins

[tex]Yellow = 12[/tex]

[tex]Green = 6[/tex]

So, the probability is:

[tex]Pr = P(Yellow)\ or\ P(Green)[/tex]

[tex]Pr = \frac{Yellow}{n} + \frac{Green}{n}[/tex]

[tex]Pr = \frac{12}{40} + \frac{6}{40}[/tex]

Take LCM

[tex]Pr = \frac{12+6}{40}[/tex]

[tex]Pr = \frac{18}{40}[/tex]

Simplify

[tex]Pr = \frac{9}{20}[/tex]

Solving (c): Expectation of orange outcomes in a spin of 500 times, theoretically.

Here, we consider the spinner itself

From the attached image, we have:

[tex]n= 5[/tex] --- i.e. 5 sections

[tex]Orange = 1[/tex]

So, the probability of having an outcome of orange in 1 spin is:

[tex]Pr = P(Orange)[/tex]

[tex]Pr = \frac{Orange}{n}[/tex]

[tex]Pr = \frac{1}{5}[/tex]

In 500 spins, the expectation is:

[tex]E(Orange) = Pr * 500[/tex]

[tex]E(Orange) = \frac{1}{5} * 500[/tex]

[tex]E(Orange) = 100[/tex]

Solving (c): Expectation of orange outcomes in a spin of 500 times, base on experiments.

Here, we consider the spinner itself

From the attached image, we have:

[tex]n= 40[/tex] --- i.e. 40 spins

[tex]Orange = 5[/tex]

So, the probability of having an outcome of orange is:

[tex]Pr = P(Orange)[/tex]

[tex]Pr = \frac{Orange}{n}[/tex]

[tex]Pr = \frac{5}{40}[/tex]

[tex]Pr = \frac{1}{8}[/tex]

In 500 spins, the expectation is:

[tex]E(Orange) = Pr * 500[/tex]

[tex]E(Orange) = \frac{1}{8} * 500[/tex]

[tex]E(Orange) = 62.5[/tex]

Answer:

50 degree

Step-by-step explanation:

70+90+angle1=180

160+angle1=180

angle1=180-160

=20

angle1+angle2+angle3=180

20+90+angle3=180

110+angle3=180

angle3=180-110

angle3=70

angle 3-angle1=(70-20)degree

=50 degree

Step-by-step explanation:  5 22 8 18 e

Graph the function and look for sign changes in the slope  (easiest)

  of the 7 roots 3 are real and 4 are complex

or the perferred way is to apply Descartes rule of signs

x^7-3x^5+4x^2-1=0        a typo in your function  attached photos shows 4x²

(x^7) - (3x^5) +(4x^2) - (1)     sign changes I see 3

then to find a bound on the number of negative roots

(-x^7) - (-3x^5) +(4x^2) - (1)    = -x^7 + 3x^5 + 4x^2 - 1     I see 2 sign changes ??

there is at least 1 real root (due the odd highest power)

and either 0, 2, 4 or 6 complex roots

so 5 and 7 are out

still confused I used a polynomials root calculator

it said ther are three real roots  (confirmed by the graph of the function)

  and four comple roots (which I can't figure out from the graph)

Answer:

The answer is most likely $120 because when you look at 12 hours on the x axis it doesn't have a point on the graph so the only highest amount is $120.

This probably doesn't make sense, but hope it helps! :)

Answer:

[tex]x = 8.64^o[/tex]

Step-by-step explanation:

Given

The attached rectangle

Required

Find x

To do this, we make use of:

[tex]11x - 5 = 90[/tex] ---- angle at diagonal

Collect like terms

[tex]11x = 5 + 90[/tex]

[tex]11x = 95[/tex]

Solve for x

[tex]x = \frac{95}{11}[/tex]

[tex]x = 8.64^o[/tex] --- approximated

Answer:

B.[tex]22^{\circ}[/tex]

Step-by-step explanation:

We are given that HMS is an isosceles triangle.

Angle M is the vertex angle.

[tex]m\angle M=(2x+6)^{\circ}[/tex]

[tex]m\angle H=(9x+7)^{\circ}[/tex]

[tex]\angle H=\angle S[/tex]

By definition of isosceles triangle

We have to find the measure of angle M.

[tex]\angle M+\angle H+\angle S=180^{\circ}[/tex]

By using sum of angles of triangle property

Substitute the values

[tex]2x+6+9x+7+9x+7=180[/tex]

[tex]20x+20=180[/tex]

[tex]20x=180-20[/tex]

[tex]20x=160[/tex]

[tex]x=\frac{160}{20}=8[/tex]

Using the value of x

[tex]m\angle M=2(8)+6[/tex]

[tex]m\angle M=22^{\circ}[/tex]

Hence, option B is correct.

Answer:

0.5 ft per min

Step-by-step explanation:

in 80 minutes the radius expanded by 40%

we can set up a proportion of percent change over minutes:

.4/80 = r/1

cross-multiply to get:

80r = .4

r = .005 or 1/2 of a foot per minute

Step-by-step explanation:

Answer:

[tex] (\frac{1}{2} ) {}^{4} = \frac{1}{ {2}^{4} } = \frac{1}{16} [/tex]

is a required answer.

Answer:

Step-by-step explanation:

Let's solve for a .

[tex]5a+6b=18[/tex]

Step 1: Add -6b to both sides.

[tex]5a+6b+−6b=18+−6b[/tex]

[tex]5a=−6b+18[/tex]

Step 2: Divide both sides by 5.

Let's solve for b.

[tex]5a+6b=18[/tex]

Step 1: Add -5a to both sides.

[tex]5a+6b+−5a=18+−5a[/tex]

[tex]6b=−5a+18[/tex]

Step 2: Divide both sides by 6.

Answer:

A. 5.8

Step-by-step explanation:

From the given graph d has two coordinates;

the first coordinates of d = (0, 0)

the second coordinate of d = (-3 , -5), that is x = -3 when traced up and y = -5 when traced horizontal

The distance between the two coordinates = distance of d;

[tex]distance \ between \ two \ coordinates = \sqrt{(x_2-x_1)^2 \ + \ (y_2-y_1)^2} \\\\d = \sqrt{(-3-0)^2 \ + \ (-5-0)^2}\\\\d = \sqrt{9 \ + \ 25} \\\\d = \sqrt{34} \\\\d = 5.83\\\\d = 5.8[/tex]

Option A is correct

Answer:

the graph one is G and the second one is C hope this helps

Answer:

[tex]\%Guitar = 33 \%[/tex]

Step-by-step explanation:

Given

The two-way table

Required

Percentage of men and women whose favorite is Guitar

From the table, we have:

[tex]Total = 200[/tex]

Those who prefer Guitar

[tex]Men=29[/tex]

[tex]Women = 37[/tex]

So:

[tex]Guitar = 29 +37 = 66[/tex]

So, the percentage of men and women is:

[tex]\%Guitar = \frac{Guitar}{Total} * 100\%[/tex]

[tex]\%Guitar = \frac{66}{200} * 100\%[/tex]

[tex]\%Guitar = \frac{6600}{200} \%[/tex]

[tex]\%Guitar = 33 \%[/tex]
