Answer: Option A

[tex]A=0.001[/tex]

Step-by-step explanation:

The sinusoidal functions have the following form

[tex]Y = Asin (bx)[/tex]

Where

[tex]\frac{2\pi}{b}[/tex] is the period of the function

A is the amplitude: Half the difference between the minimum value and the maximum value of the function.

In this case the function is:

[tex]y = 0.001sin(880\pi\phi)[/tex]

Therefore the amplitude of this equation is [tex]A=0.001[/tex]

Answer:

y = 7/5x + 18/5

Step-by-step explanation:

so we have y = mx + b

f(1) = 5

f(-4) = -2

so let's find b

so like if you do (5 - (-2))/(1 - (-4)) you get (5 + 2)/(1 + 4) = 7/5

y = 7/5x + b

so now we can plug in a value like f(1) = 5

5 = (7/5)1 + b

b = 18/5

Answer:

We need 4/5 cups of oil

Step-by-step explanation:

We can use ratios to solve.  Put the amount of oil over the number of batches

2/3  cup          x cups                    

---------------- = --------------

2.5 batches      3 batches

Using cross products

2/3 * 3 = 2.5 *x

2 = 2.5 x

Divide each side by 2.5

2/2.5 = 2.5x/2.5

.8 =x

Changing this back to a fraction

4/5 =x

We need 4/5 cups of oil

Let's talk about what we do know, before we answer the question.

Probability =  (1/2)^5 x (1/2) = 1/64 or 1.5625%, which rounds to -

1.6% [C] <----------

Final answer:

The probability of tails coming up on the 6th flip of a coin is calculated as (0.5)^6, which equals 0.015625 or 1.6% after rounding to the nearest tenth of a percent.

Explanation:

To calculate the probability of tails coming up on the 6th flip of a coin, we must first understand that each flip of a fair coin is an independent event with two possible outcomes: heads or tails. The probability for each of these outcomes on a single flip is 50% or 0.5. In order for tails to come up on the 6th flip specifically, we need to have five heads before that. The probability of getting heads five times in a row is (0.5)^5, and then we multiply this by 0.5 again for the probability of the 6th flip being tails. Hence, the calculation is (0.5)^6.
(0.5)^6 = 0.015625, which is the same as 1.5625%. Rounding this to the nearest tenth of a percent, the probability of tails coming up on the 6th flip is 1.6%, which corresponds to option C.

Seems like you had your minus signs backwards. Try y = 3 and y = -6

Answer:

c

Step-by-step explanation:

Answer:

1. C.

2. B.

3. Add 6.1 to both sides

Step-by-step explanation:

1. Your equation here is "w + 2 < -1"

You must get w by itself, so to do that, subtract 2 from both sides.

w + 2 < -1

w < -3

Notice that the symbol is "w is less than -3" not "w is less than or equal to -3," so our plot must have a closed circle (or no open circle).

The larger the number behind the negative sign, the smaller it is.

ex: -3 is smaller than -1

So, the answer is C.

2. Here, you have the inequality -15 > q - 5

To find out which number set best fits the inequality, substitute the numbers in for the q value.

[I'll skip to answer B.]

B.'s number set is {-11, -12, -14}

So, plug in each value for q

For -11:

-15 > (-11) - 5

-15 > -16

This works.

(As I mentioned earlier, the larger the number in front of the negative, the smaller it is.)

For -12:

-15 > (-12) - 5

-15 > -17

This works as well

For -14:

-15 > (-14) - 5

-15 > -19

This works too

Thus, the answer is B.

3. And finally, you have the equation p - 6.1 = 10

To solve for p, make sure its alone on one side of the equation.

To do this, add 6.1 to both sides.

This is the first (and pretty much only) step to solve this equation

I hope this helps!!! :)

*Fifty percent of the people who subscribed to Tech Monthly bought a 1-year subscription.

*Twenty-six percent of all the magazine subscriptions sold were for Teen Charm.

Step-by-step explanation:

We have to examine each statement against the data provided in the data table to see if it's a supported statement or no.

*A total of 120 magazine subscriptions were sold.

FALSE. 200 were sold (adding up all 1-yr and 2-yrs subscriptions)

*Fifty percent of the people who subscribed to Tech Monthly bought a 1-year subscription.

TRUE. 22 bought the 1-yr subscription, and 22 bought the 2-yr subscription

*Twenty-six percent of all the magazine subscriptions sold were for Teen Charm.

TRUE.  total subscriptions were 200 as seen above, and 52 were for Teen Charm... so 52/200 = 26%

*Of all the magazine subscriptions sold, 66 2/3% were 2-year subscriptions.

FALSE.  80 2-yr subscriptions were sold, out of 200... so 80/200 = 40%

Step-by-step explanation:

[tex]\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height\\ \cline{1-1} A=8\\ h=4 \end{cases}\implies 8=\cfrac{1}{2}b(4)\implies 8=2b\implies \cfrac{8}{2}=b\implies 4=b[/tex]

To find the length of the base of a triangle with an area of 8 square feet and a height of 4 feet, you rearrange the formula for the area of a triangle and solve for the base, resulting in a base length of 4 feet.

The question asks for the length of the base of a triangle given that the area is 8 square feet and the height is 4 feet. To find the base of the triangle, we can rearrange the formula for the area of a triangle, which is A = (1/2) * base * height. Substituting in the given values and solving for the base, we get:

Base = (2 * Area) / Height

Next, we replace the values for Area and Height:

Base = (2 * 8 sq ft) / 4 ft

Base = 16 sq ft / 4 ft

Base = 4 feet

Therefore, the length of the base of the triangle is 4 feet.

g(x) = x^2 - x

g(2/3) = (2/3)^2 - 2\3 = 4/9 - 2/3 = 4/9 - 6/9 = -2/9

Answer:

-2/9

Step-by-step explanation:

g(x) = x² - x

Substitute x = 2/3 into g(x).

g(2/3)

= (2/3)²  - (2/3)

= 4/9 - 2/3

= 4/9 - 6/9

= -2/9

Distributed property because this property allows u two put 4r+2r because this equation is also (4xr)+(2xr) since they have the same variable u can put them together 4+2 is 6 and then just multiply by r so it’s 6r. And let’s not forget about 3s it doesn’t have the same variable so you can do 6r+3s which is what u got and is the correct answer 6r+3s is simplified but it’s the same as 4r+3s+2r

Answer:

-4 < x ≤ 8

Step-by-step explanation:

You want x in the middle of your compound inequality. All you need to do is write these using x only once:

-4 < x ≤ 8

9/30 cubic feet

Multiply the base area times the height to find the volume, which is the amount of packing material required.

First, multiply the numerators, or the top numbers. 9 * 1 = 9

Then, multiply the denominators, or the bottom numbers. 10 * 3 = 30

So, the amount of packing material required is 9/30 cubic feet.

Answer:

[tex]P =0.857[/tex]

Step-by-step explanation:

We know that 60% of students have an iPad and a car and 70% have a car.

If we call A the event "have an iPad" and call the event B "have a car"

So

[tex]P (A\ and\ B) = 0.6\\\\P(B) = 0.7[/tex]

We look for the probability that a student with a car also has an iPad. This is

[tex]P (A | B) = \frac{P(A\ and\ B)}{P(B)}\\\\P (A | B) = \frac{0.6}{0.7}\\\\P (A | B) = 0.857[/tex]

Answer:

86%

Step-by-step explanation:

To solve this problem you need to use the formula for conditional probability.  

P(Ipod|Car) = P(Car and Ipod)P(Car).

P(a student with a car also has an iPod) = 0.6/0.7 = 0.857 = 86%

90 is 50% of 180

50% = half

90 • 2 = 180

The expression is 180 is 50 percent of 90

From the question, we have the following parameters that can be used in our computation:

90 is 50 percent of what number

Represent the percentage with x

So, we have

90 is 50 percent of x

Mathematically, we have

50% * x = 90

So, we have

x = 90/50%

Express percentage as decimal

x = 90/0.50

Evaluate the expression

x = 180

Hence, the number in the percentage is 180

Step-by-step explanation:

The cyclist's speed converts to 43.2 km/h. In 3 hours, she will travel a distance of 129.6 kilometers.

The rate of the cyclist in kilometers per hour can be calculated by converting meters per second to kilometers per hour. To do this, we multiply the speed in meters per second by 3.6 (since 1 m/s = 3.6 km/h). Thus, the cyclist's speed in km/h is 12 m/s * 3.6 = 43.2 km/h.

To calculate the distance she will travel in 3 hours, we multiply the speed (in km/h) by the time in hours. So, the distance is 43.2 km/h * 3 hours = 129.6 km.

The cyclist's rate in kilometers per hour is 43.2 km/h, and she will travel 129.6 km in 3 hours.

To convert the rate from meters per second (m/s) to kilometers per hour (km/h), we need to use conversion factors.

Conversion factors:

1 m/s = 3.6 km/h

1 hour = 3600 seconds

Let's calculate:

Rate in km/h = (Rate in m/s) × (Conversion factor from m/s to km/h)

Rate in km/h = 12 m/s × 3.6 km/h

Rate in km/h = 43.2 km/h

To calculate the distance traveled in 3 hours, we can use the formula:

Distance traveled = Rate × Time

Distance traveled = 43.2 km/h × 3 hours

Distance traveled = 129.6 km

Answer:

y > -1/3x - 1

Step-by-step explanation:

The inequality is a linear inequality whose equation can be written using a form similar to y = mx + b. Remember m is the slope and b is the y-intercept. Here the line crosses the y-axis at b = -1. And it has as a slope m = -1/3. The equation is then y = -1/3x - 1. Since this is an inequality with a dashed line then the symbols <,> must replace the =. There are two options:

y < -1/3x - 1 and y > -1/3x - 1

Test the point (0,0) which is in the solution set to determine which equation holds true.

0 < -1 and 0 > -1

The first is false and the second is true. The correct equation is y > -1/3x - 1

Answer:

The glue stick with 3/8

Step-by-step explanation: if you make the denominators for both equations the same 1/5 would turn into 8/40 and 3/8 would turn into 15/40. This means that 3/8 would be 7% bigger  

The second glue stick has [tex]\( \frac{7}{40} \)[/tex] more glue than the first glue stick.

To compare the amount of glue left in each glue stick, we need to find a common denominator for [tex]\( \frac{1}{5} \)[/tex] and [tex]\( \frac{3}{8} \)[/tex].

The least common denominator (LCD) for 5 and 8 is 40.

Now, let's rewrite [tex]\( \frac{1}{5} \)[/tex] and [tex]\( \frac{3}{8} \)[/tex] with the common denominator of 40:

[tex]\[ \frac{1}{5} = \frac{1 \times 8}{5 \times 8} = \frac{8}{40} \]\[ \frac{3}{8} = \frac{3 \times 5}{8 \times 5} = \frac{15}{40} \][/tex]

Now, we can compare the amounts:

- Glue stick 1: [tex]\( \frac{8}{40} \)[/tex] left.

- Glue stick 2: [tex]\( \frac{15}{40} \)[/tex] left.

Since [tex]\( \frac{15}{40} \)[/tex]is greater than [tex]\( \frac{8}{40} \)[/tex], the second glue stick has more glue left.

Alternatively, we can also subtract the fractions to find the difference:

[tex]\[ \frac{15}{40} - \frac{8}{40} = \frac{15 - 8}{40} = \frac{7}{40} \][/tex]

Answer:

William is 18, Monica is 6... 6 x 3=18 Three times as old.. in 6 years William will be 24, Monica will be 12.. Twice as old... 12 x 2= 24

Step-by-step explanation:

Answer:

Current age of Monica=6 years

and current age of William=18 years

Step-by-step explanation:

Let Monica's current age be x years and William's current age be y years.

William is 3 times elder than Monica.

⇒  y=3x

In 6 years William will be twice as old as Monica.

⇒ y+6=2(x+6)

⇒ y+6=2x+12

⇒3x+6=2x+12

⇒ x=6

Hence, y=3×6=18

That means, current age of Monica=6 years

and current age of William=18 years

Answer is A because when you work it out the area is 110.500 and rounding it makes it -

1/6 < 1/4 so 1/6 would equal 2/12 and 1/4 would equal 3/12 so which means if you take one from each it would be 5/12 but if you took 2 from the first one it would only be 2/12 which is why you need to read correctly because THE REASON MARK IS CORRECT IS BECAUSE 5/12 IS GREATER THAN 2/12

Hence opposite=6 units and adjacent=5 units.

The hypotenuse is,

[tex] = \sqrt{ {5}^{2} + {6}^{2} } = \sqrt{61} [/tex]

Since the terminal side is in the third quadrant, the cosine ratio is negative.

[tex] \cos( \theta) = - \frac{adjacent}{hypotenuse} [/tex]

[tex]\cos( \theta) = - \frac{5}{ \sqrt{61} } [/tex]

Rationalize the denominator,

[tex]\cos( \theta) = - \frac{5\sqrt{61}}{ 61 } [/tex]
