Answer:

6.75

Step-by-step explanation:

So basicly we know the area of the rectangle which really helpful.

So lets take the formula of the are for the triangle, which is b*h*1/2

So we know that the height and bass of the triangle is the same as the rectangle's legnth and width.

Meaning that we can replace b*h with 13.5.

So plug that into the quation.

13.5*1/h= Area of ACE

6.75= Area of ACE

hence, 6.75 is your answer

The area of the triangle ACE is; 6.75 square units.

According to the question; a triangle is inscribed in a rectangle with each vertex of the triangle lieing on a side of or at a vertex of the rectangle.

In essence, to find the number of square units in the area of shaded triangle ACE,

We have to divide the area of the rectangle by 2.

Therefore, the area of the triangle ACE is;

6.75 square units.

Answer:

The answer would be A, or line LJ, line KL, and line JK.

Step-by-step explanation:

You can tell which lines are smaller by using the angle measurements. The direction from which the angle is shown points to their respected line.

So, angle K goes with line LJ

Angle J goes with line LK

And angle L goes with line JK.

The size of the angle determines the size (not actual size) of the line.

Answer:

Co-efficient of [tex]x^{2}[/tex] is missing.

It should be 8[tex]x^{2}[/tex].

Step-by-step explanation:

Given two polynomials:

1st polynomial: [tex]15x^2+11y^2+8x[/tex]

2nd polynomial: [tex]-7x^2+5y^2+2x[/tex]

To find:

The value in the blank:

[tex](15x^2+11y^2+8x)-(7x^2+5y^2+2x)= \_\_ \ x^2+6y^2+6x[/tex]

Solution:

Here, we have 3 pair of like terms.

2 terms with [tex]x^{2}[/tex], 2 terms with [tex]y^{2}[/tex]and 2 terms with [tex]x[/tex].

Like terms can be subtracted.

Subtracting the terms with [tex]y^{2}[/tex], the coefficients will get subtracted.

[tex]11y^2 - 5y^2 = 6y^2[/tex]

Subtracting the terms with [tex]x[/tex], the coefficients will get subtracted.

[tex]8x -2x=6x[/tex]

Subtracting the terms with [tex]x^{2}[/tex], the coefficients will get subtracted.

[tex]15x^2 - 7x^2 =\bold{8}x^2[/tex]

Therefore, the answer is:

Co-efficient of [tex]x^{2}[/tex] is missing.

It should be 8[tex]x^{2}[/tex].

Answer: x-4

Step-by-step explanation:

1. Factor the numerator

(x-4)(x-4)

2. Cancel out factors between the numerator and denominator (if applicable)

(x-4)(x-4)/(x-4)

Since x-4 appears in both the numerator and denominator, you can cancel the factors out, as they are equal to 1, leaving the answer, x-4

pop quiz?

Answer:

The sales price of the skirt was $14.3.

Step-by-step explanation:

From the information given, you know that the total for the three items is $32.35 which is:

x+y+z=32.35

x is a skirt

y is a pair of shoes

z is a pair of socks

Also, you know that the pair of socks costs $3.75, so you can replace the value of z and subtract this from the total amount to have the price of the skirt plus the pair of shoes:

x+y+3.75=32.35

x+y=32.35-3.75

x+y=28.6

Now, as the original prices of the skirt and shoes were the same and you know that the sum of the two items is equal to $28.6, you can divide this by 2:

$28.6/2=$14.3

According to this, the answer is that the sales price of the skirt was $14.3.

Answer:

343 cubic feet

Step-by-step explanation:

A company rents a storage unit. The unit is in the shape of a cube.

The formula V=s^3 can be used to find the volume of a cube.

Using the formula, determine the volume of the storage unit if the side length (s) is 7 feet.

From the above question

Side length (s) = 7 feet

Formula for the cube = V = s³

Volume of the cube(storage unit) = (7 feet)³

= 343 cubic feet

Answer:

21 feet

Step-by-step explanation:

To solve this question, we would be using the proportion

Shadow /Height

From the question:.

Manny's shadow = 414 feet

Manny's Height = 512 feet

Height of the tree = ? = x

Shadow of the tree = 17 feet

Hence:

414/512 = 17/ x

Cross Multiply

414 × x = 512 × 17

x = 512 × 17/414

x = 21.024154589 feet

x ≈ Approximately = 21 feet

The height of the tree = 21 feet

The height of the tree is 21 feet.

Given that,

Based on the above information, the calculation is as follows:

[tex]414\div 512 = 17\div x\\\\414 \times x = 512 \times 17\\\\x = 512 \times 17\div 414[/tex]

x = 21.02

= 21 feet

Therefore we can conclude that the height of the tree is 21 feet.

Answer:

14.14 ft long

Step-by-step explanation:

Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft². How long is the side length of the carpet?

The Area the carpet covers is a square.

Hence, the Area of a square = (Side length)²

From the question, we are given the Area of the square = 200 ft²

Hence:

200 ft² = (Side length)²

We square root both sides.

√200 ft² = √(Side length)²

Side length = 14.142135624 ft

Approximately = 14.14 ft

The side length of the carpet is 14.14 ft long

Answer:

Data provide convincing evidence of a difference in SAT scores  between students with and without a military scholarship is explained below in details.

Step-by-step explanation:

This is a quiz of 2 autonomous groups. The population model differences are not understood. it is a two-tailed examination. Let w be the index for scores of students with army research and o be the index for scores of students without army research.

Therefore, the population means would be μw and μo.

The irregular variable is x w - xo = variation in the sample mean records of students with military accomplishments and students without.

For students with military accomplishments,

n = 8

Mean = (850 + 925 + 980 + 1080 + 1200 + 1220 + 1240 + 1300)/8

Mean = 1099.375

Standard deviation = √(summation(x - mean)/n

Summation(x - mean) = (850 - 1099.375)^2 + (925 - 1099.375)^2 + (980 - 1099.375)^2 + (1080 - 1099.375)^2 + (1200 - 1099.375)^2 + (1220 - 1099.375)^2 + (1240 - 1099.375)^2 + (1300 -1099.375)^2 = 191921.875

Standard deviation = √(191921.875/8 = 154.89

For students without military scholarship,

n = 12

Mean = (820 + 850 + 980 + 1010 + 1020 + 1080 + 1100 + 1120 + 1120 + 1200 + 1220 + 1330)/12

Mean = 1073.83

Summation(x - mean) = (820 - 1073.83)^2 + (850 - 1073.83)^2 + (980 - 1073.83)^2 + (1010 - 1073.83)^2 + (1020 - 1073.83)^2 + (1080 - 1073.83)^2 + (1100 - 1073.83)^2 + (1120 - 1073.83)^2 + (1120 - 1073.83)^2 + (1200 - 1073.83)^2 + (1220 - 1073.83)^2 + (1330 - 1073.83)^2 = 238199.4268

Standard deviation = √(238199.4268/12 = 140.89

We would set up the hypothesis.

The null hypothesis is

H0 : μw = μo H0 : μw - μo = 0

The alternative hypothesis is

Ha : μw ≠ μo Ha : μw - μo ≠ 0

Since sample standard deviation is recognized, we would analyis the examination statistic by using the t examination. The formula is

(xw - xo)/√(sw²/nw + so²/no)

From the information given,

xw = 1099.375

xo = 1073.83

sw = 154.89

so = 140.89

nw = 8

no = 12

t = (1099.375 - 1073.83)/√(154.89²/8 + 140.89²/12)

t = 0.37

The formula for determining the degree of freedom is

df = [sw²/nw + so²/no]²/(1/nw - 1)(sw²/nw)² + (1/no - 1)(so²/no)²

df = [154.89²/8 + 140.89²/12]²/(1/8 - 1)(154.89²/8)² + (1/12 - 1)(140.89²/12)² = 21650688.37/1533492.15

df = 14

We would get the probability count from the t test calculator. It becomes

p value = 0.72

Since the level of importance of 0.05 < the p value of 0.72, we would not neglect the null hypothesis.

Therefore, these data do not present an acceptable indication of a difference in SAT scores between students with and without a military scholarship.

Part B

The formula for getting the confidence interval for the difference of two population means is expressed as

z = (xw - xo) ± z ×√(sw²/nw + so²/no)

For a 95% confidence interval, the z score is 1.96

xw - xo = 1099.375 - 1073.83 = 25.55

z√(sw²/nw + so²/no) = 1.96 × √(154.89²/8 + 140.89²/12) = 1.96 × √2998.86 + 1654.17)

= 133.7

The confidence interval is

25.55 ± 133.7
