Answer:

B I hope

Step-by-step explanation:

The length of the base of a square prism is 3.872 cm and the surface area of a square prism is 184.9 cm ²

Let h is the height length of the prism and a is the length of base edge.

then the volume is a²h and the surface area is 2a²+4ah

(a) The volume of a square prism is 150 cm³ and  10 cm is height length

Let a is the length of base edge.

We know the volume is a²h.

Substitute the values

a²(10) = 150

     a² = 15

      a = √15

      a = 3.872 cm

Since length of base is 3.872 cm.

(b) The height length of the prism is 10 cm and the base edge length is √15 cm.

We know the surface area is 2a²+4ah

Substitute the values

S = 2(√15)² + 4 (3.87 )(10)

  =  2(15) + 40(3.87)

  = 30 + 154.91

  = 184.9 cm ²

Since the surface area of a square prism is  184.9 cm ².

Step-by-step explanation:

Answer:

[tex]\bar x = 1.4896[/tex]

[tex]Median = 1.525[/tex]

7 is an outlier

Step-by-step explanation:

Given

See comment for dataset

Solving (a): The mean

The mean is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

[tex]\bar x = \frac{2.53 +1.33 +0.64 +2.55 +0.67 +0.57 +............+2.03 +1.78}{50}[/tex]

[tex]\bar x = \frac{74.48}{50}[/tex]

[tex]\bar x = 1.4896[/tex]

Solving (b): The median

First, we sort the data:

[tex]0.01, 0.01, 0.08, 0.14, 0.24, 0.35, 0.57, 0.64, 0.65, 0.67,[/tex]

[tex]0.69, 0.74, 0.81, 0.82, 0.92, 0.99, 1.01, 1.04, 1.15, 1.16, 1.33,[/tex]

[tex]1.41, 1.45, 1.48, 1.52, 1.53, 1.58, 1.61, 1.62, 1.73, 1.77, 1.78, 1.84,[/tex]

[tex]1.98, 2.01, 2.02, 2.03, 2.06, 2.06, 2.31, 2.41, 2.53, 2.55, 2.59,[/tex]

[tex]2.66, 2.74, 2.74, 2.77, 2.77, 2.91[/tex]

The median position is:

[tex]Median = \frac{n + 1}{2}[/tex]

[tex]Median = \frac{50 + 1}{2}[/tex]

[tex]Median = \frac{51}{2}[/tex]

[tex]Median = 25.5th[/tex]

This means that the median is the average of the 25th and the 26th item.

So:

[tex]Median = \frac{1.52+1.53}{2}[/tex]

[tex]Median = \frac{3.05}{2}[/tex]

[tex]Median = 1.525[/tex]

Solving (c): Is 7 an outlier

Yes; 7 is an outlier.

Because the range of the dataset (0.01 to 2.92) is far from 7.

Answer:

A)

3a2 – 2b2 – 2c2 – ab + 5ac + 5bc

[tex](3a + 2b - c)(a - b + 2c) \\ = (3 {a}^{2} - 3ab + 6ac + 2ab - 2 {b}^{2} + 6bc - ac + bc - 2 {c}^{2} ) \\ = 3 {a}^{2} - ab + 5ac - 2 {b}^{2} + 5bc - {2c}^{2} \\ = 3 {a}^{2} - 2 {b}^{2} - {2c}^{2} - ab + 5ac + 5bc[/tex]

Answer:

option a is correct

Step-by-step explanation:

(3a + 2b - c)(a - b + 2c)

3a(a- b + 2c) +2b(a - b + 2c) - c(a - b + 2c)

multiply the brackets

3a^2 - 3ab + 6ac + 2ab - 2b^2 + 4bc - ac + bc - 2c^2

combine like terms

3a^2 - ab + 5ac - 2b^2 + 5bc - 2c^2

3a^2 - 2b^2 - 2c^2 - ab + 5ac + 5bc

Answer:

Dominic ate [tex]\frac{2}{6}[/tex]  of the pizza.

Step-by-step explanation:

First you want to convert the fractions so they all have the same denominator (bottom number in the fraction.) That will make it a lot easier to add and subtract with them.

[tex]\frac{1}{2}[/tex] = [tex]\frac{3}{6}[/tex]

So Shawn ate 1/6 of the pizza, and Ryan ate 3/6 of the pizza. To find what else makes up the whole pizza (what Dominic ate) we add 1/6 and 3/6, then subtract from the whole.

[tex]\frac{1}{6}[/tex] + [tex]\frac{3}{6}[/tex] = [tex]\frac{4}{6}[/tex]

[tex]\frac{6}{6}[/tex] - [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{6}[/tex]

Therefore Dominic ate [tex]\frac{2}{6}[/tex]  of the pizza.

Answer:

  B.  F(-9/2, 0), x = 9/2

Step-by-step explanation:

One definition of a parabola is that it is all of the points that are equidistant from the focus and the directrix. Among other things, this means the parabola "wraps around" the focus, and opens away from the directrix.

The focus is on the axis of symmetry, so shares a coordinate with the vertex. Since the vertex is a point on the parabola, it is equidistant from the focus and directrix—halfway between them.

The given equation has x get more negative as y increases, so the parabola opens to the left. This means the focus will be a point on the -x axis. Only one answer choice meets that requirement:

  focus: (-9/2, 0), directrix: x = 9/2

__

The equation of a parabola with its vertex at the origin can be written as ...

  x = 1/(4p)y^2

In this case, we have 4p = -18, so p = -9/2. This is the distance from the vertex to the focus. The negative sign means the focus is to the left of the vertex, and its x-coordinate is -9/2 (as noted above).

Answer:

3 white to 5 yellow

the third choice

Step-by-step explanation:

white     9 parts

yellow   15 parts

9 white to 15 yellow

Divide by 3

3 white to 5 yellow

4xy² + 3x -5 polynomial example

example of a polynomial

this one has 3 terms

Dividing

polynomial division

Polynomials can sometimes be divided using the simple methods shown on Dividing Polynomials.

But sometimes it is better to use "Long Division" (a method similar to Long Division for Numbers)

Numerator and Denominator

We can give each polynomial a name:

x² + 2x -7 (numerator)

_________

x-2 (denominator)

[tex] \times - {}^{2} \sqrt{ \times {}^{2} } + 2 \times - 7[/tex]

Both polynomials should have the "higher order" terms first (those with the largest exponents, like the "2" in x2).

then :

divide: the first term of the numerator

by the first term of denominator and put that answer

multiply the denominator by that answer, put that below the numerator

subtract to create a new polynomial

repeat using the polynomial

Answer:

Area = 84 square unit

Step-by-step explanation:

Given the triangle is right angle triangle. According to Pythagoras theorem, the largest amount the sides is the hypotenuse. and the others are base and height respectively.

Therefore, hypotenuse = 25, base = 7, height = 24

[tex]Area \ of \ triangle = \frac{1}{2} \times \ base \times height[/tex]

                        [tex]= \frac{1}{2} \times 7 \times 24 \\\\= 7 \times 12 \\\\= 84 \ square \ unit[/tex]

Answer:

A = 84 units^ 2

Step-by-step explanation:

The longest side length is also the hypotenuse of this right triangle:  25.  Therefore the leg lengths must be 7 and 24.  The legs are perpendicular to one another.  If we let the base be 7 and the height 24, then the area of the triangle is A = (1/2)(base)(height), or

A = (1/2)(7)(24) = 84 units^ 2

Answer:

2.28% of faculty members work more than 58.6 hours a week.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average full-time faculty member in a college works an average of 53 hours per week. Standard deviation of 2.8 hours.

This means that [tex]\mu = 53, \sigma = 2.8[/tex]

What percentage of faculty members work more than 58.6 hours a week?

The proportion is 1 subtracted by the p-value of Z when X = 58.6. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{58.6 - 53}{2.8}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a p-value of 0.9772

1 - 0.9772 = 0.0228

0.0228*100% = 2.28%

2.28% of faculty members work more than 58.6 hours a week.

Answer:

282.12 ft

Step-by-step explanation:

Please find attached a graphical illustration of the question

We are given the value of the opposite side and we are to determine the value of the adjacent side. Thus, tan would be used

Tan 65 = opposite / adjacent

2.1445 = 605 / x

x = 605 / 2.1445

x = 282.12 ft

Answer:

Hence the correct option is Option b that is the same for each interval.

Step-by-step explanation:

The PDF for Uniform distribution in [a,b] is given by  

[tex]f(x)=\frac{1}{b-a}~~~~~~a\leq x\leq b[/tex]  

So the probability that the random variable assumes a value in​ [a,b] is given by  

[tex]\int_{a}^{b}f(x)dx=\int_{a}^{b}\frac{1}{b-a}dx=1[/tex]

Therefore the correct option is b. the same for each interval.
