Answer:

Step-by-step explanation:

Given that Jared made [tex]12\frac{3}{4}[/tex] cups of snack mix for a party.

Let x be the cups of snacks mix made by Jared.

Therefore  [tex]x=12\frac{3}{4}[/tex]

His guests eat [tex]\frac{2}{3}[/tex] of the mix.

Let y be the guest eated snacks mix

Therefore [tex]y=\frac{2}{3}[/tex]

Let z be the number of snacks did Jared's guest eat

Therefore z=x-y

[tex]z=12\frac{3}{4}-\frac{2}{3}[/tex]

[tex]=\frac{51}{4}-\frac{2}{3}[/tex]

[tex]=\frac{51(3)-2(4)}{4\times 3}[/tex]

[tex]=\frac{153-8}{12}[/tex]

[tex]=\frac{145}{12}[/tex]

[tex]=12\frac{1}{12}[/tex]

Therefore [tex]z=12\frac{1}{12}[/tex]

Explanation:

The question involves calculating the number of ways to choose a committee consisting of 9 women from a group of 13 women, and 4 men from a group of 8 men. This is a problem that requires knowledge of combinations, a concept in probability and statistics.

Step-by-step solution:

Now, using the combination formula:

After calculating, we find that the number of ways to form the committee is 50,050, which corresponds to option (A).

Answer:

A x=3.1

Step-by-step explanation:

1/2(4x+6)=-5x+24.7

Multiply each side by 2 to get rid of the fraction

2*1/2(4x+6)=2(-5x+24.7)

4x+6 = -10x +49.4

Add 10x to each side

4x+6+10x=-10x+10x+49.4

14x +6 = 49.4

Subtract 6 from each side

14x+6-6 = 49.4-6

14x = 43.4

Divide each side by 14

14x/14 = 43.4/14

x = 3.1

It takes 2 seconds to reach a maximum height of 69 feet, and the range is [5, 69].

The equation is of the form

h(t) = -16t² + v₀t + h₀, where -16 is the gravitational constant, v₀ is the initial velocity, and h₀ is the initial height.  Using the values from our problem, we have:

h(t) = -16t² + 64t + 5

To find the maximum height, we find the vertex.  The first step in this is to find the axis of symmetry, which is given by -b/2a:

-64/2(-16) = -64/-32 = 2

This is our value for t, so it takes 2 seconds to reach the maximum.  Substituting this into our function, we have

h(2) = -16(2²) + 64(2) + 5 = -64 + 128 + 5 = 64 + 5 = 69

This is the maximum height.

The range of heights goes from 5 to 69, inclusive, or [5, 69].  

The T-Shirt reaches its maximum height of 104 feet at 2.5 seconds. The range of the height over time is from 4 feet to 104 feet.

To analyze the projectile motion of the T-Shirt, we'll use the kinematic equations. The height h(t) at any time t can be modeled by the equation:

h(t) = -16t2 + v0t + h0

where:

1. Time to reach maximum height:

To find the time to reach maximum height, we use the formula for the time at which the velocity becomes zero:

t = v0 / g

t = 80 ft/s / 32 ft/s2 = 2.5 s

2. Maximum height:

Now, substituting t = 2.5 s into the height equation, we get:

h(2.5) = -16(2.5)2 + 80(2.5) + 4

h(2.5) = -100 + 200 + 4 = 104 feet

3. Range of the height function:

The T-Shirt starts at 4 feet, reaches a maximum of 104 feet, and is caught at 35 feet. Hence, the range of the height function is [4, 104] feet.

Answer:

Note that for graph, Y = mx + c, where m = slope of graph and c = y-intersect

1) equation of line: y = [tex]-\frac{3}{4} x[/tex] + 4         ∴ m = -3/4 ,  c = 4

2) equation of line: y = [tex]\frac{3}{2} x[/tex] + 3              m = 3/2 ,   c = 3

3) equation of line: y = [tex]-\frac{2}{5} x[/tex] - 2            m = -2/5 ,  c = -2

4) equation of line: y = [tex]\frac{1}{2} x[/tex] + 3              m = 1/2 ,     c = 3

5) equation of line: y = -x + 2               m = -1 ,       c = 2

6) equation of line: y = [tex]-\frac{5}{2} x[/tex] - 1             m = -5/2 ,   c = -1

Step-by-step explanation:

For each of the line equations, "m" is the slope which is also dy/dx. Also the intersect "c" is on the y axis(Vertical line).

For each equation, assume a number for 'x' then solve for y.... you will be able to get coordinates (x,y) for each graph.

Using 1) as example:

1) equation of line: y = [tex]-\frac{3}{4} x[/tex] + 4         ∴ m = -3/4 ,  c = 4

at intersection 'c', y = 4, when x = 0

∴ y = -3/4 (1) + 4  = [tex]3\frac{1}{4}[/tex]

repeat for x = 2, 3, 4, 5, 6

Do same for equation line 2, 3, 4, 5, 6 to get coordinates to plot each graph

The measure of angle E is 75°.

Solution:

Given data:

∠E = 5x, ∠F = 7x – 13 and ∠R = –2 + 6x

A quadrilateral inscribed in a circle is called cyclic quadrilateral.

∠R and ∠G are opposite angles in a cyclic quadrilateral.

In cyclic quadrilateral, opposite angles are supplementary.

⇒ m∠R + m∠F = 180

⇒ –2 + 6x + 7x – 13 = 180

⇒ 13x – 15 = 180

Add 15 from both sides of the equation, we get

⇒ 13x = 195

Divide by 13 from both sides of the equation, we get

⇒ x = 15

To find the measure of angle E:

m∠E = 5x

m∠E = 5(15)

m∠E = 75

The measure of angle E is 75°.

The maximum amount that Amelia may have to pay back for the fraudulent charges of $1,600 made on her card is $50.

Two or more expressions with an Equal sign is called as Equation.

According to the Fair Credit Billing Act (FCBA) in the United States, a consumer's liability for unauthorized charges on a credit card is limited to $50.

Amelia will be responsible for paying the first $50 of the fraudulent charges, but she will not be held responsible for any charges above that amount.

However, most credit card companies have a zero liability policy, which means that the consumer will not be responsible for any unauthorized charges made on their credit card.

Hence, the maximum amount that Amelia may have to pay back for the fraudulent charges of $1,600 made on her card is $50.

Answer:

f(-3) = g(-3)

Step-by-step explanation:

Remember points on the graph get their location from the x-axis (horizontal) and y-axis (vertical).

In function notation, "f(x)" means when "x" is the value in the brackets, what the value of "y" will be.

First option for example: f(-3) = g(4)

Value of "y" for f(x) when x = -3:

On the blue line, when x = -3, y = -4.

Value of "y" for g(x) when x = 4:

On the red line, when x = 4, y = -3.

Therefore:

f(-3) = g(4)

-4 = -3          <= This is false.

In the third option: f(-3) = g(-3)

On f(x) blue, when x = -3: y = -4

On g(x) red, when x = -3: y = -4

Therefore:

f(-3) = g(-3)

-4 = -4                <= This is true.

Step-by-step explanation:

The expected amount is $12.50.

The Probability in mathematics is possibility of an event in time. In simple words how many times that incident is happening in any given time interval.

There are 8 possibilities, if coin is flipped three times.

HHH, HHT, HTH, TTH, HTT, THT and TTH,

where H is possibility of head and T is tail.

Now the probabilities,

0 tails: 1 way out of 8 total: P(0) = 1/8

1 tails: 3 ways out of 8 total: P(1) = 3/8

2 tails: 3 ways out of 8 total: P(2) = 3/8

3 tails: 1 way out of 8 total: P(3) = 1/8

The expected amount;

(1/8)X 0 + (3/8)X 5 +(3/8)X15 +(1/8)X40

= 15/8 + 45/8 + 40/8

Answer:

D. 12:11pm

(10:05am + 3hrs 6mins = 1:11pm - 1hr = 12:11pm)

Final answer:

After accounting for the flight duration of 3 hours and 6 minutes and the one-hour time difference due to the Central Standard Time Zone, Doris will arrive in Houston at 12:11 p.m. local time.

Explanation:

Doris is taking a flight from New York to Houston, and we need to calculate the local time of her arrival in Houston after a 3-hour-6-minute flight. To find the answer, we must account for the time zone difference and the duration of her flight. New York is in the Eastern Standard Time Zone, while Houston is in the Central Standard Time Zone, which is one hour behind New York.

Starting from a departure time of 10:05 a.m. in New York, we first add the flight duration which is 3 hours and 6 minutes. This gets us to 1:11 p.m. New York time. Since Houston is one hour behind New York, we subtract one hour from this time to get the local time in Houston, which will be 12:11 p.m.

The correct answer is D. 12:11 p.m. This is the time Doris will arrive in Houston, local time.

The first three statements are false because they are opposite from the data shown in the graph, while the two last statements are true.

To determine whether a statement is true or false, you need to:

This statement is false, this is because time does not change with temperature, and therefore time is an independent variable. The corrected statement would be Temperature is a function of time.

In the graph, you can see the lowest temperature was 67° and this occurred between 11 and 12 p.m. Therefore, the lowest temperature occurred between 11:00 and 12:00.

Based on the graph from 9 to 10 p-m the temperature went from 70° to almost 65°. Therefore the temperature was decreasing between 9:00 and 10:00.

This statement is true, this temperature occurred at 3:00 and 4:00.

This statement is true, the temperature is the same between 5:00 and 9:00.
