Answer:

The expression 4a - 2(a + b) + 1 simplifies to -3 when a = 2 and b = 4.

Step-by-step explanation:

When a = 2 and b = 4, substituting the values into the expression gives:

4 * 2 - 2 * (2 + 4) + 1 = 8 - 2 * 6 + 1 = 8 - 12 + 1 = -4 + 1 = -3

So the expression 4a - 2(a + b) + 1 simplifies to -3 when a = 2 and b = 4.

Answer:

Linear

Step-by-step explanation:

It goes up by 2 each time, so it would be linear.

If you rolled two dice, recorded the face values and summed them up, you would be collecting quantitative data. This is because quantitative data is numerical in nature and involves counting, measuring or quantifying something.

In this case, the numbers on the faces of the dice would be counted and added together to obtain a total sum. This data can be further classified as discrete since the possible outcomes of rolling dice are limited to a set of discrete values.

Therefore, this data can be easily analyzed using statistical methods to determine the probability of certain outcomes occurring. Collecting quantitative data is essential in many fields such as science, economics, and finance, as it provides valuable insights into the behavior and trends of various phenomena.

In this situation, the face values on the dice represent numbers, and the sum of these values is also a number. The data you collect can be analyzed using statistical methods and can provide meaningful insights.

Answer:

The formula for the volume of a triangular prism is given by:

V = (1/2)bhL

where b is the base length of the triangle, h is the height of the triangle, and L is the length of the prism (i.e., the distance between the two triangular faces).

We are given the area of the rectangular surface of the prism, which is the product of the lengths of two adjacent sides of the rectangle, and we know that this area is equal to 864 cm^2. Therefore, we can use the Pythagorean theorem to find the length of the third side of the rectangle, which is also the base length of the triangular face:

17^2 = 9^2 + 10^2

289 = 81 + 100

289 = 181

So, the base length of the triangular face is 8 cm. Now we can plug in the known values into the formula for the volume of the prism:

864 = (1/2)(8 cm)(h)(L)

We are not given the length of the prism, L, but we know that it is equal to the base length of the triangle, which is 8 cm. Therefore, we can simplify the equation to:

864 = 32h

Solving for h, we get:

h = 864/32

h = 27

So the height of the prism is 27 cm.

Answer:

Step-by-step explanation:

For one flower, the following shapes are used;

6 yellow hexagons, 2 red trapezoids and 9 green triangles

If we are given 30 yellow hexagons 50 red trapezoids and 60 green triangles, to get the number of flowers we can make, we will find the greatest common factor of 30, 50 and 60

30 = 6*5

50 = (2*5)+40

60 = (9*5)+15

We can see that 5 is common to all the factors. This means that we can make 5 flowers if they were changed to 30 yellow hexagons 50 red trapezoids and 60 green triangles.

Since there are 40 trapezoids left and 15 green triangles left, hence the shape that would have n as left over most is trapezoid (40 left over)

After the store gives 20% off sale, the expression of the item at price p can be written as, p-0.2=0.8p.

Given to us

A store is having a 20% off sale.

The sale price of an item with price p is p – 0. 2p.

We know that for any item the price can be 100%(1.00) of itself, therefore, the price of the item will be p.

We know that for any item the price can be 100%(1), therefore, after giving 20%(0.2) off sale, the price will be 80%(1-0.2 = 0.8) of the original.

Thus, the expression is equivalent to

\((100\%)p-(20\%)p = 80\%p\\\\1p-0.2p = 0.8p\\\\p-0.2p=0.8p\)

Hence, after the store gives 20% off sale, the expression of the item at price p can be written as, p-0.2=0.8p.

For ray LH as the bisector of angle GLI, we can determine that the relation ∠GLI = 2∠GLH holds

An angle is formed from the intersection of two lines. Types of angles are acute, obtuse and scalene.

∠GLI is bisected by LH, hence:

∠GLH = ∠HLI (definition of bisection)

∠GLI = ∠GLH + ∠HLI (angle addition)

∠GLI = 2∠GLH

(a) The probability that the modified dental anxiety scale score is higher than 13 is approximately 0.3085. (b) The probability that the score is lower than 10 is approximately 0.4013. (c) The probability that the score is between 15 and 20 is approximately 0.1465. (d) A score of approximately 20.32 will have only 1% exceeding it. (e) A score of approximately 7.64 will have only 20% lower than it.

To solve the given problems, we can utilize the properties of the normal distribution and standardize the scores using z-scores.

(a) Probability that the score is higher than 13:

First, we calculate the z-score:

z = (13 - 11) / 4 = 0.5

Using a standard normal distribution table or a calculator, we find the probability associated with the z-score of 0.5, which is approximately 0.3085. Therefore, the probability that the score is higher than 13 is 0.3085.

(b) Probability that the score is lower than 10:

Similarly, we calculate the z-score:

z = (10 - 11) / 4 = -0.25

Using the standard normal distribution table or a calculator, we find the probability associated with the z-score of -0.25, which is approximately 0.4013. Therefore, the probability that the score is lower than 10 is 0.4013.

(c) Probability that the score is between 15 and 20:

We calculate the z-scores for both values:

z1 = (15 - 11) / 4 = 1

z2 = (20 - 11) / 4 = 2.25

Using the standard normal distribution table or a calculator, we find the probabilities associated with the z-scores of 1 and 2.25. The probability associated with z = 1 is approximately 0.8413, and the probability associated with z = 2.25 is approximately 0.9878. Therefore, the probability that the score is between 15 and 20 is 0.9878 - 0.8413 = 0.1465.

(d) Modified dental anxiety scale score for which only 1% will exceed (higher than)

We need to find the z-score that corresponds to the cumulative probability of 0.99 (1% will exceed). Using the standard normal distribution table or a calculator, we find the z-score associated with a cumulative probability of 0.99, which is approximately 2.33. We can then use the z-score formula to find the corresponding score:

x = (z * standard deviation) + mean

x = (2.33 * 4) + 11

x ≈ 20.32

Therefore, a modified dental anxiety scale score of approximately 20.32 will have only 1% exceeding (higher than) it.

e) Modified dental anxiety scale score for which only 20% will be lower than, We need to find the z-score that corresponds to the cumulative probability of 0.20 (20% will be lower than).

Using the standard normal distribution table or a calculator, we find the z-score associated with a cumulative probability of 0.20, which is approximately -0.84. We can then use the z-score formula to find the corresponding score:

x = (z * standard deviation) + mean

x = (-0.84 * 4) + 11

x ≈ 7.64

Therefore, a modified dental anxiety scale score of approximately 7.64 will have only 20% lower than it.

Hence <1 = <3

Given < 1 = 3x-1 and <3 = 2x+9

Hence 3x-1 =  2x+9

collect like terms

3x-2x = 9+1

x = 10°

Since <1 = 3x-1

on substituting x = 10

<1 = 3(10)-1

<1 = 30-1

Let x be the greater of the two consecutive integers, then the other integer is x-1. The product of the two integers is given as 342, so we can write the equation:

x(x-1) = 342

Expanding the left side and rearranging, we get:

\(x^{2}\) - x - 342 = 0

Therefore, the quadratic equation that can be used to find x, the greater number, is D.\(x^{2}\)-x-342=0.

If we solve  4x-3y=3, -8x +6y=-6 by substitution or elimination, we will have x=3/4 and y=0

We have the following simultaneous equations:

4x-3y=3.....................(i)

-8x+6y=-6..................(ii)

We solve using substitution:

Make x the subject of formula in equation(i):

4x=3+3y

x=(3+3y)/4

Now, replace the value of x in equation(ii)

-8x+6y=-6, and x=(3+3y)/4

-8((3+3y)/4)+6y=-6

-2(3+3y)+6y=-6

-6-6y+6y=-6

y=0

Now, we replace the value of y=0 in any equations we have to find the corresponding value of x:

4x-3y=3, but y=0
