(PLEASE HELP) The histogram shows the number of hours that 25 college students spent studying for their final exams. Which statement is true about this histogram?

Answer:

342

Step-by-step explanation:

Let's see the difference is each successive values:

232 - 217 = 15

252 - 232 = 20

277 - 252 = 25

307 - 277 = 30

As we can see, each month the increase is 5 more than previous months' increase. Clearly from the pattern we can surmise that the next month (August), it will increase by 35 from the value of July.

Number of visitors in August = Number of Visitors in  July + 35 = 307 + 35 = 342

Answer:

Ben had biked 8 miles

Step-by-step explanation:

You would need to take 12 and divide it by three . That would make 4. After that you would take 4 and multiply it by 2 since he rode 2/3 miles of 12.  Then you would end up with 8.

Final answer:

Ben has biked 8 miles of the 12 miles he wants to, as he has completed 2/3 of his intended distance.

Explanation:

To calculate the number of miles Ben has biked, we simply need to multiply the total distance he wants to bike by the fraction of the trip he has completed. Ben wants to bike 12 miles, and he has biked 2/3 of that distance. Multiplying these together gives us 2/3 * 12 = 8 miles. Therefore, Ben has biked 8 miles so far.

It’s (x-6)(x+4) so the first one and last one

For this case we must factor the following expression:

[tex]x ^ 2-2x-24[/tex]

We must find two numbers that when added together give "-2" and when multiplied by "-24"

These numbers are:

[tex]-6\ and\ +4\\-6 + 4 = -2\\-6 * + 4 = -24[/tex]

So:

[tex]x ^ 2-2x-24 = (x-6) (x + 4)[/tex]

Answer:

[tex](x-6) (x + 4)[/tex]

Option A and D

➷ Find the total number of pens:

5 + 3 + 2 = 10

The probability of taking a red the first time is 5/10

The probability of taking a blue the first time is 3/10

The probability of taking a green the first time is 2/10

If you want to take the same colored pen again, there would be 1 less of the total pen (as it hasn't been replaced) and there would be one less of that color (as one has already been taken)

Therefore:

The probability of taking a red again is 4/9

The probability of taking a blue again is 2/9

The probability of taking a green again is 1/9

Multiply the values for the same color together:

5/10 x 4/9 = 20/90

3/10 x 2/9 = 6/90

2/10 x 1/9 = 2/90

Add these values together:

20/90 + 6/90 + 2/90 = 28/90

Your answer is 28/90

Make the equations equal to 180° because they are on a straight line. And a straight line adds up to 180°

Yes there is because the change of rate for both the x and y-values is 2. It has a consistant rate of change.

Answer:

y = 54.1

Step-by-step explanation:

The big triangle is divided in two: one on  the left and one on the right. Lets start working with the right one.

We know the right triangle is a right triangle with legs 24 and 36, so we can use Pitagoras to find the hypotenuse (h), in a way that:

24^2 + 36^2 = h^2

1872 = h^2

Applying sqr root in both sides:

h = 43.27

So, the hypotenuse measures 43.27 or 43.3.

Now lets do the same with the triangle of the right which legs are 36 and y, lets find it hypotenuse (g):

36^2 + y^2 = g^2

1296 + y^2 = g^2

Now we will pass to the large triangle, which is composed by the left and the right triangles and has legs of 43.3 and g, and the hypotenuse is 24+y. Lets apply Pitagoras:

43.3^2 + g^2 = (24+y)^2

1875 + 1296 + y^2 = 24^2 + 48y + y^2

3171 + y^2 = 576 + 48y + y^2

As we have y^2 in both sides we can eliminate them

3171 + = 576 + 48y

Now subtract 576 in both sides:

3171 -576 = 576 + 48y - 576

2595 = 48y

Divide both sides by 48:

2595/48 = 48y/48

54.1 = y

So, the large hypotenuse measures 54.1+24 = 78.1. Lets verify:

43.3 ^2 + 1296 + 54.2^2 = 6,108.53

And the sqrd root of 6,108.53 is approximately 78.1. Verified!!!!

So, we can confirm: y = 54.1

Both rectangles have the same dimensions and shape. P'Q'R'S' is a translated image of PQRS, shifted 3 units right and 3 units up. They are congruent but not identical due to their position.

Step-by-step comparison of rectangles PQRS and P'Q'R'S':

1. Original coordinates:

Assume specific coordinates for the vertices of rectangle PQRS. For example, let P = (1, 2), Q = (5, 2), R = (5, 6), and S = (1, 6).

2. Translation:

A translation moves every point in the shape the same distance and in the same direction. Since Rashid translated rectangle 3 units up and 3 units to the right, add 3 to x-coordinate and 3 to y-coordinate of each point in PQRS to find corresponding points in P'Q'R'S'.

3. New coordinates:

P' = (1 + 3, 2 + 3) = (4, 5)

Q' = (5 + 3, 2 + 3) = (8, 5)

R' = (5 + 3, 6 + 3) = (8, 9)

S' = (1 + 3, 6 + 3) = (4, 9)

4. Comparison:

Shape:

Both rectangles PQRS and P'Q'R'S' are rectangles because a translation preserves the shape of the original figure.

Size:

They have the same dimensions (length and width) as the translation only shifts the position without altering the size.

Orientation:

They maintain the same orientation relative to the axes, meaning their sides remain parallel and perpendicular to the x and y axes.

Position:

The key difference lies in their position. P'Q'R'S' is located 3 units to the right and 3 units above PQRS.

5. Rectangles PQRS and P'Q'R'S' are congruent (same size and shape) but not identical (different positions).

P'Q'R'S' is a translated image of PQRS, moved 3 units to the right and 3 units up.

[tex]35+3x-15+x=180[/tex]             combine like terms

[tex](35-15)+(3x+x)=180[/tex]

[tex]20+4x=180[/tex]           subtract 20 from both sides

[tex]4x=160[/tex]          divide both sides by 4

[tex]x=40[/tex]

Answer:

y = - [tex]\frac{1}{4}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - [tex]\frac{1}{4}[/tex], hence

y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

To find c substitute (12, 2) into the partial equation

2 = - 3 + c ⇒ c = 2 + 3 = 5

y = - [tex]\frac{1}{4}[/tex] x + 5 ← equation of line

It would go between 7.32 and 7.37

Answer:

Step-by-step explanation:

Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.

2(6.3) + b = 15.7

12.6 + b = 15.7

b = 15.7 - 12.6

b = 3.1

Answer:

Equation that can be used to find length of the base is b + 12.6 = 15.7  and the length of the base we get from this equation is 3.1 cm

Step-by-step explanation:

Given:

Length of the equal side of the Isosceles Triangle = a

Length of the base of the triangle = b

Equal sides are longer than base of the triangle.

Perimeter of the triangle = 15.7 cm

Equation representing given information = 2a + b = 15.7

To find: Equation that represent or can be used to find length of the base if longer side = 6.3 cm

Given Equation is the Equation representing the perimeter of the isosceles triangle.

Longer side  = 6.3 cm = Length of the Equal Sides of the triangle.

So, a = 6.3 cm

Now,

2 × 6.3 + b = 15.7

b + 12.6 = 15.7

b = 15.7 - 12.6

b = 3.1 cm

Therefore, Equation that can be used to find length of the base is b + 12.6 = 15.7  and the length of the base we get from this equation is 3.1 cm

Step-by-step explanation:

Part 1)

Possible outcomes of cube={1,2,3,4,5,6}

Possible outcomes of coin=(H,t}

Now,  Andrew rolls the number cube once and flips the coin once

then possible outcome that contains only the outcomes in which the number cube lands on a number less than 3 are:

(1,H),(2,H)(1,T),(2,T)

Part 2)

Given:

population=1500 dogs

spots containing dogs= 15 out of every 125 dogs in the population have spots

spots containing dogs:

                                =1500/125

                                     =12    

                                     =12*15

                                     =180    

dogs in the population that do NOT have spots on their back

=1500-180=1320

Part 4)

Given:

classical songs=2

rock songs=13

rap=5

total songs= 2+13+5

                                     =1/4

Part 5)

Given:

3 Characters= elf, hobbit, or human

4 tools= magic, sword, shield, slingshot, or umbrella

Probability of first event , P(C)= 1/3

Probability of second event, P(T)=1/5

As both events are mutually exclusive so

P(magic elf)= P(C)*P(T)

                 =1/3+1/5

                 =1/15 !

Answer:

The correct answer option is x = -16 and x = 16.

Step-by-step explanation:

We are given the following equation and we are to find the solution for this equation:

[tex] | \frac { x } { 2 } | = 8 [/tex]

For the given equation, involving the modulus, we will have a positive as well as a negative value for it in order to find its solution set.

[tex] \frac { x } { 2 } = - 8 [/tex] and [tex] \frac { x } { 2 } = 8 [/tex]

[tex] x = 8 \times 2 [/tex] and [tex] x = - 8 \times 2 [/tex]

x = -16 and x = 16

Answer:

The correct answer is last option

x = -16 or x = 16

Step-by-step explanation:

it is given that,

|x/2| = 8

To find the solution set

From this we can understand that , the value of x/2 = - 8 or x/2 = 8

If x/2 = -8 then  x = -8 * 2 = = -16

If x/2 = 8 then x = 8 * 2 = 16

Therefore the solutions are

x = -16 or x = 16

Answer: option D.

Step-by-step explanation:

To solve this exercise you must apply the proccedure shown below:

- Apply the Distributive property (Remember that when you multiply two powers with the same base, you must add the exponents).

[tex]b^m*b^n=b^{(m+n)}[/tex]

- Add the like terms.

Therefore, you obtain that the product is:

[tex](2x^2+5x-3)(3x+7)=6x^3+14x^2+15x^2+35x-9x-21\\=6x^3+29x^2+26x-21[/tex]

An expression is defined as a set of numbers, variables, and mathematical operations. The product of (2x²+5x-3) and (3x+7) is 6x³ + 29x² + 26x - 21.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The product of (2x²+5x-3) and (3x+7) can be done as,

(2x²+5x-3) × (3x+7)

= 3x(2x²+5x-3) + 7(2x²+5x-3)

= 6x³ + 15x² - 9x + 14x² + 35x - 21

= 6x³ + 29x² + 26x - 21

Hence, the product of (2x²+5x-3) and (3x+7) is 6x³ + 29x² + 26x - 21.
