Step-by-step explanation:

Answer:

a) V = 288 - h

b) (0,288)(1,276)(2,264)(3,252)(4,240)

c) graph the above point

d) Volume decreases as height increases

Step-by-step explanation:

Step 1 :

a)

The given equation is V = 12(24-h)

Using the distributive property we have

V= 12*24 - 12 * h = 288-h

b)

The ordered pairs (h,V) can be obtained by giving different values for h and computing the corresponding V values

When h = 0 ,V= 288 -0= 288

When h = 1 ,V= 288 -12*1= 276

When h = 2 ,V= 288 -12*2= 264

When h = 3 ,V= 288 -12*3= 252

When h = 4 ,V= 288 -12*4= 240

Hence the ordered pairs are (0,288)(1,276)(2,264)(3,252)(4,240)

Step 3 :

The above points can be graphed using the values of h in the x axis and the values of V in the y axis

Step 4:

The above equation shows that the value of the volume V decreases as the value of h increases and becomes negative for values of h >24

152 pencils cost $304

To find the inverse function f−1(x) for f(x)=√(2x−6), we first express f(x) as y, swap x and y, remove the square root by squaring both sides, solve for y, and substitute -4 into the new expression. This calculation reveals that f−1(-4) is 11.

To find the value of f−1(-4) for the function f(x)=√(2x−6), we need to find the value of x such that f(x) equals -4. Here is how to find the inverse function:

To find f−1(-4), substitute -4 into the inverse function:

y = ((-4)² + 6)/2

y = (16 + 6)/2

y = 22/2

y = 11

Therefore, f−1(-4) = 11.

To find f−1(−4) for the function f(x) = √(2x − 6), solve for x in terms of y, square both sides, solve for x, and then substitute the value to find that f−1(−4) equals 11.

To find the value of f−1(−4) for the function f(x) = √(2x − 6), follow these steps:

Solve for x in terms of y by setting y = f(x):
y = √(2x − 6)

Square both sides to eliminate the square root:
y2 = 2x − 6

Solve for x:
x = (y2 + 6) / 2

Replace y with x to get f−1(x):
f−1(x) = (x2 + 6) / 2

Now, find f−1(−4):
f−1(−4) = (−42 + 6) / 2 = (16 + 6) / 2 = 22 / 2 = 11

Thus, the value of f−1(−4) is 11.

Final answer:

To determine the probability of drawing one red bead and one white bead from a bag, calculate the probability of each sequence (red then white, white then red) occurring and add them together. The result is that the probability that one bead of each color is taken is 4/11.

Explanation:

To find the probability that one red bead and one white bead are taken from a bag containing 7 red beads and 4 white beads (11 beads in total), we follow these steps:

Calculate the probability of drawing one red bead first and then one white bead.

Calculate the probability of drawing one white bead first and then one red bead.

Add the probabilities from step 1 and 2 together to find the total probability of drawing one bead of each color.

The probability of drawing one red bead first is 7/11 since there are 7 red beads out of 11 total beads.

After drawing a red bead, there are now 10 beads left in the bag, with 4 being white. So, the probability of drawing one white bead next is 4/10.

Multiplying these two probabilities gives us the probability of this particular sequence occurring: (7/11) * (4/10) = 28/110, which reduces to 2/11 when simplified.

We do a similar calculation for the reverse sequence, where a white bead is drawn first followed by a red bead. The probability for the first white bead is 4/11, and for the red bead after that, it's 7/10 since one white bead is already taken.

Multiplying these probabilities gives us: (4/11) * (7/10) = 28/110, which also simplifies to 2/11.

Finally, to find the total probability we add the probabilities of both sequences together: 2/11 + 2/11 = 4/11.

So, the probability that one bead of each color is taken is 4/11.

Answer:

Option D.

Step-by-step explanation:

Recall that the wider the confidence interval, the greater the variability.

In other words, wider confidence interval will have bigger sample standard deviation.

For option A, the width is |48-42|=6

For option B, the width is |50-40|=10

For option C, the width is |55-35|=20

For option D, the width is |45.5-44.5|=1

Therefore the team in option D has the smallest sample standard deviation.

As for the confidence level, it is just telling us the extent to which we confidence that, the parameter is within the interval

x = 8 3/6

Step-by-step explanation:

6(x+4) = 75

6X+24 = 75

     -24 = -24

   6x -0 = 51

   6x/6  = 51/6

       x    = 8 3/6

The first step in solving equation is divide by 6 both side and x = 8.5.

To simplify simply means to simplify something. Simply or simplification in mathematics refers to simplifying an expression, fraction, or problem. By writing the fraction in its simplest or lowest form and canceling all common factors from both the numerator and denominator, it simplifies fractions and makes the problem easier to solve.

Given 6(x + 4) = 75

divide both side by 6

(6(x + 4))/6 = 75/6

x + 4 = 12.5

subtract 4 from both sides

x + 4 - 4 = 12.5 - 4

x = 8.5

Hence value of x is 8.5 and first step in solving the equation is divide by 6.

Answer:

c = 17

Step-by-step explanation:

Use the Pythagorean Theorem to solve this problem.

The equation is a² + b² = c².

"a" and "b" are the length of the two shorter sides or values.

"c" is the length of the longest side or value, also the hypotenuse.

Since we know the two smaller values, we can replace "a" and "b" with 8 and 15. It does not matter which letter you decide to replace with which number.

Then simplify and  isolate "c" to find the largest value.

a² + b² = c²

8² + 15² = c²         Substitute "a" and "b". Square the numbers to simplify

64 + 225 = c²        Add to simplify

289 = c²        

√289 = √c²        Square root both sides

√289 = c      "c" will be isolated because √ and ² are reverse operations

c = √289    Put 'c' on the left side for standard formatting.

c = 17           Answer

Therefore the largest value, c, is 17 in the triple.

Final answer:

Using the Pythagorean theorem, a² + b² = c², we find that the largest value in the Pythagorean triple with the smallest values 8 and 15 is 17.

Explanation:

If 8 and 15 are the two smallest values in a Pythagorean triple, we can use the Pythagorean theorem to find the largest value, often denoted as c, in the triple. The formula for the Pythagorean theorem is a² + b² = c². Solving for c gives us c = √(a² + b²).

Using 8 as a and 15 as b, we can substitute these values into the equation:

c = √(8² + 15²)

c = √(64 + 225)

c = √289

c = 17

Therefore, the largest value in the Pythagorean triple is 17.

Answer:

if you found this off edge its Option B

Step-by-step explanation:

Answer:

Step-by-step explanation:

Plant B is taller than Plant C.  We need to determine by how much.  To do this, we divide 6 2/3 inches by 4 4/15 inches.  The LCD is 15, and so we have:

6 10/15       100/15

----------- or ------------- = 100/64 = 20/16 = 5/4

4 4/15           64/15

Plant B is 1 and 1/4 times taller than Plant C.  This can be restated as Plant C is four fifths as tall as Plant B.

Plant C is shorter than Plant B, as we saw earlier.  The difference is found through subtraction:  100/15 - 64/15 = 36/15 inches = 12/5 inches shorter, or 2 2/5 inches shorter

Plant C is approximately 12 4/5 times as tall as Plant B. Plant C is approximately 2 2/5 inches shorter than Plant B.

To find out how many times larger Plant C is compared to Plant B, we need to divide the height of Plant C by the height of Plant B. In this case, Plant C is 4 4/15 inches tall and Plant B is 6 2/3 inches tall.

So, the calculation would look like this:

4 4/15 ÷ 6 2/3

To divide fractions, we need to convert the mixed numbers into improper fractions. So, Plant C is 64/15 inches tall and Plant B is 20/3 inches tall.

Now we can divide the fractions:

64/15 ÷ 20/3 = (64/15) x (3/20)

Cancel out common factors:

64/5 ÷ 1/1 = 64/5 = 12 4/5

Plant C is approximately 12 4/5 times as tall as Plant B.

To find out whether Plant C is taller or shorter than Plant B, we need to subtract their heights. Plant C is 4 4/15 inches tall and Plant B is 6 2/3 inches tall.

So, the calculation would look like this:

4 4/15 - 6 2/3

Again, we need to convert the mixed numbers into improper fractions:

Plant C is 64/15 inches tall and Plant B is 20/3 inches tall.

Now we can subtract the fractions:

64/15 - 20/3 = (64/15) - (20/3

To subtract fractions, we need to have the same denominator. So, we need to find a common denominator for 15 and 3, which is 15.

64/15 - 100/15 = -36/15 = -2 6/15 = -2 2/5

Plant C is approximately 2 2/5 inches shorter than Plant B.
