Answer: I believe the answer is 25%.

Answer:

The slope is 2.2

Step-by-step explanation:

Since the point goes  through (0,0) the slope is given by

m =y/x

4.4 / 2

2.2

Answer:

(a) 0.15866

(b) Clustered, with two peaks

(c) Point estimate is 6.3 inches

Margin of error is 0.7 inches

(d) Yes

(e) Stratified sampling method

Step-by-step explanation:

(a) The given information are as follows

Mean diameter of Aspen trees, μ = 8 inches

Standard deviation, σ = 2.5 inches

[tex]z = \frac{x - \mu}{\sigma} = \frac{5.5 - 8 }{2.5} = -1[/tex]

Therefore;

p(x < 5.5) = p(z < -1)

From the z score table, we have p = 0.15866

Therefore, the probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches = 0.15866

(b) The distribution of the Aspen trees can be described as clustered and having two peaks around 9.25 inches and 5.25 inches

(c) The point estimate is 5.6 + (7.0 - 5.6)/2 = 6.3

The margin of error = (7.0 - 5.6)/2 = 0.7 inches

(d) Yes, because the 8 inches is outside the range

(e) Stratified sampling method

Here, the Aspen trees are separated into the highland and lowland samples such that the measurement required will be representative of both highlands park and lowlands park.

Answer:

1/9

Step-by-step explanation:

The area of a polygon is the old area multiplied by the scale factor squared

New area = old area ( SF) ^2

The scale factor is 1/3

(1/3) ^2 = 1/9

The fraction is 1/9

Answer:

0.1

Step-by-step explanation:

10,000 * (1/100,000) = 0.1

Step-by-step explanation:

a= the height of the triangle=h

[tex]h^{2} = ef[/tex]

by ef, e= 18 & f=4

so...

[tex]h^{2} = 18 \times 4 = 72[/tex]

so you put both of them in a square root

[tex] \sqrt{h} = \sqrt{72}[/tex]

so the answer will be

[tex]h = \sqrt{72} = 6 \sqrt{2} [/tex]

Answer:Do you mean find p?  If so then p+10 = 90 - 49, so p = 31°.  Another possibility is in the second quadrant where p + 10 = 180 - 41 so p = 129°  (The 41 comes from the first p+10, i.e. 31+10 = 41),

Answer:

1312 miles

Step-by-step explanation:

To solve this, we simply need to subtract the distance she traveled in her trips to Chicago from the distance she traveled in her trips to Louisville.

She made 4 round trips to​ Chicago, Illinois​. Each of the trips is a distance of 218 miles. This means that the total distance she traveled is:

4 * 218 = 872 miles

She made 6 round trips to​ Louisville, Kentucky​/ Each of the trips is a distance of 364 miles. This means that the total distance she traveled is:

6 * 364 = 2184 miles

Therefore, the difference between the distances she traveled is:

2184 - 872 = 1312 miles

She traveled 1312 miles more in her trips to Louisville than in her trips to Chicago.

Answer:

45 degrees

Step-by-step explanation:

The sum of the angles of a triangle always adds up to 180.

10x + 8x + 5 + 85 = 180

Simplify by combining like terms.

18x + 90 = 180

Subtract 90 from both sides.

18x = 90

Divide both sides by 18.

x = 5 degrees

But the question didn't ask for x, it asked for angle A. So plug back in.

A = 8x + 5

A = 8(5) + 5

A = 40 + 5 = 45 degrees

Answer:

[tex]45 \: \: degrees[/tex]

Step-by-step explanation:

[tex]10x + 8x + 5 + 85 = 180 \\ 18x + 90 = 180 \\ 18x = 180 - 90 \\ 18x = 90 \\ \frac{18x}{18} = \frac{90}{18} \\ x = 5[/tex]

[tex]angle \: \: \: a = 8x + 5 \\ = 8 \times 5 + 5 \\ = 40 + 5 \\ = 45 \: \: degrees[/tex]

Answer:a and c

Step-by-step explanation:

The number of the minutes for loading 6 tires to a truck will be 186. If he works for 93 minutes. Then the number of tires can he fit will be 3.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Liam is a tire fitter.

It takes him 124 minutes to fit 4 tires to a truck.

The number of minute for the loading of one tire will be

⇒ 124 / 4

⇒ 31 minutes per tire

a) Then the number of the minutes for loading 6 tires to a truck will be

⇒ 31 × 6

⇒ 186 minutes

b) If he works for 93 minutes. Then the number of tires can he fit will be

⇒ 93 / 31

⇒ 3 tires

The number of the minutes for loading 6 tires to a truck will be 186. If he works for 93 minutes. Then the number of tires can he fit will be 3.

Answer:

Remember:  to divide by a fraction (such as 10/3 here), invert the divisor fraction and multiply instead:

Answer: length*width

Step-by-step explanation:

The base of a cube is a square. As long as you can find the area of a square, you can find the base of a cube. A=Area. A=length*width or A=lw. This works the same for rectangular prisms, but with rectangles AND squares.

Answer:

g(x) = 3(x-9)(x-5)

Zeros: x = 9 and x = 5.

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

In this question:

[tex]g(x) = 3x^{2} - 42a + 135[/tex]

So

[tex]a = 3, b = -42, c = 135[/tex]

[tex]\bigtriangleup = (-42)^{2} - 4*3*135 = 144[/tex]

[tex]x_{1} = \frac{-(-42) + \sqrt{144}}{2*3} = 9[/tex]

[tex]x_{2} = \frac{-(42) - \sqrt{144}}{2*3} = 5[/tex]

So

g(x) = 3(x-9)(x-5)

Zeros: x = 9 and x = 5.
