Yukio says the scale from DEF to ABC is 3:1. Is Yukio Correct? Explain

Step-by-step explanation:

Assuming that Triangle DEF and ABC have the same angles (they do because they are right-angled), we can take the length from the larger triangle (DEF) and divide it by the length of the smaller triangle (ABC).

Length of DEF = 6cm

Length of ABC = 2cm

= 6/2

= 3

Proves that scale of DEF to ABC is 3:1

The heights of women aged 20 to 29 are approximately Normal with mean 64 inches and standard deviation 2.7 inches. Men the same age have mean height 69.3 inches with standard deviation 2.8 inches. What are the z-scores for a woman 6 feet tall and a man 5'10" tall? (You may round your answers to two decimal places) z-scores for a woman 6 feet tall: z-scores for a man 5'10" tall:

Answer: The z-scores for a woman 6 feet tall is 2.96 and the z-scores for a a man 5'10" tall is 0.25.

Step-by-step explanation:

Let x and y area the random variable that represents the heights of women and men.

Given : The heights of women aged 20 to 29 are approximately Normal with mean 64 inches and standard deviation 2.7 inches.

i.e.

Since ,

Then, z-score corresponds to  a woman 6 feet tall (i.e. x=72 inches).

[∵  1 foot = 12 inches , 6 feet = 6(12)=72 inches]

Men the same age have mean height 69.3 inches with standard deviation 2.8 inches.

i.e.

Then, z-score corresponds to a man 5'10" tall (i.e. y =70 inches).

[∵  1 foot = 12 inches , 5 feet 10 inches= 5(12)+10=70 inches]

∴ The z-scores for a woman 6 feet tall is 2.96 and the z-scores for a a man 5'10" tall is 0.25.

Calculate the total cost of an item bought at a negotiated price of $14,380, a$2,700 trade-in allowance, a sales tax of 7.2 percent, and a $79 registration fee.$14266.08

$13,689.35$12,794.36

$12,599.96 Answers The total cost of an item bought at a negotiated price of$14,380 is $12495.36. Item bought at a negotiated price of$14,380, a $2,700 trade-in allowance, A sales tax of 7.2 percent, and a$79  registration fee.

Let us find the cost of the item after 7.2% of sales tax.

What is the cost?

A cost is an expenditure required to produce or sell a product or get an asset ready for normal use.

The cost of an item after 7.2% of sales tax will be equal to 15640 plus 7.2% of 15640.

The cost of items after sales tax

Therefore the cost of an item after 7.2% of sales tax will be 15415.36

Now let us add the registration fee to the cost of the item.

The cost after registration fees is to the cost of items

=15415.36+79

=15495.36

Now let us subtract $2700 trade allowance to find the total cost of the item. =15495.36- 2700 =12795.36 Therefore the total cost is$12495.36.

Find the distance between (-8, -2)
and 6, -1)

The distance between the given coordinate points is units.

The given coordinate points are (-8, -2) and (6, -1).

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On plane the distance between two points and is Distance .

Substitute and in distance formula, we get

Distance

Distance

Distance

Distance units

Therefore, the distance between the given coordinate points is units.

9. There are at least a couple of ways to approach this. The law of sines can be used to find the length of another side. Given two sides and the angle between them, a formula gives area.

Law of Sines

... a/sin(A) = c/sin(C)

Multiplying by sin(C) gives

... c = sin(C)·a/sin(A) = 19·sin(64°)/sin(20°) ≈ 49.9301

The angle between sides a and c is B, which has the value ...

... B = 180° -A -C = 180° -20° -64° = 96°

Then the area of the triangle is ...

... Area = (1/2)ac·sin(B) = (1/2)(19)(49.9301)(0.994522) ≈ 471.737 ≈ 471.7

10. Heron's formula will give the area of a triangle from its side lengths.

... s = (a+b+c)/2 = (51+38+45)/2 = 67

... Area = √(s(s-a)(s-b)(s-c)) = √(67·16·29·22) = √683936 ≈ 827.004 ≈ 827.0
