Answer:

8.38

Step-by-step explanation:

The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.

Answer:

A. 210

Step-by-step explanation:

Answer:

3, 3

Step-by-step explanation:

[tex]n^2 - 6n + 9 = 0 \\ n^2 - 3n - 3n+ 9 = 0 \\ n(n - 3) - 3(n - 3) = 0 \\ (n - 3)(n - 3) = 0 \\ n - 3 = 0, \: \: n - 3 = 0 \\ n = 3, \: \: n = 3[/tex]

Thus, the two numbers are 3, 3

Answer:

Option C is your answer

Step-by-step explanation:

21,22,  23,  26,29,  32,  34,38,  40,  42,43

Yes, Q1 is 23, median is 32, Q3 is 40

So the box should start on 23, end on 40, and have its inner line over 32.

In your picture, that's option C

Answer:its c

Answer:

y=2/5x+8/5

Step-by-step explanation:

so say you plot a graph of rain against the hours the gradient would be the rate of change and the information given as your points and the gradient

now to get an equation of a straight line use one of your points eg(1,2) and the gradient or rate of change mine was 0.4

It would most likely equal to 6. Hope this helped.

Answer:

so you have a 40% chance or 2/5 chance

Step-by-step explanation:

30 numbers in total

12 are less than 13

so you have a 12/30

simplify

2/5 = 0.4 or 40%

Answer:

x = 150

Step-by-step explanation:

(n-2)180       (n = the amount of sides)

(12 - 2)180

(10)180

1800

1800/12 = 150

Answer:

9

Step-by-step explanation:

mn ~Jk

mn x 5/3 = 15

mn = 15 x 3/5

MM = 9

Answer:

[tex]A=200.96\ unit^2[/tex]

Step-by-step explanation:

Given that,

The circumference of the circle, C = 50.24 units

We need to find the area of the circle.

The formula for the circumference of the circle is given by :

[tex]C=2\pi r[/tex]

r is the radius of the circle

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{50.24}{2\times 3.14}\\\\r=8\ units[/tex]

The formula for the area of a circle is given by :

[tex]A=\pi r^2\\\\A=3.14\times 8^2\\A=200.96\ unit^2[/tex]

So, the area of the circle is equal to [tex]200.96\ unit^2[/tex].

Answer:

divied by 100 and remove the "%" sign.

Step-by-step explanation:

1.)example 10% becomes 10/100=0.10

2.) example 67.5% becomes 67.5/100=0.675

Answer:

[tex]\sqrt{28}[/tex]

Step-by-step explanation:

It is given that the triangle (QRS) is right, thus one can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states,

[tex](a)^2+(b)^2=(c)^2[/tex]

Where (a) and (b) are the legs or the sides adjacent to the right angle and (c) is the hypotenuse or the side opposite the right angle. The unknown side in the triangle is a leg, thus, let (b) represent this value. Substitute in the given values and solve,

[tex](6)^2+(b)^2=(8)^2\\\\36+b^2=64\\\\b^2=28\\\\b=\sqrt{28}[/tex]

Answer:

  3 ≤ n ≤ 10 means "three is less than or equal to n, which is less than or equal to 10"

  you're concerned with polygons having 3 to 10 sides, inclusive.

Step-by-step explanation:

The symbol ≤ means "less than or equal to." The compound inequality ...

  3 ≤ n ≤ 10

means the value of n may range from 3 to 10, inclusive.

  heptagon, octagon, nonagon, decagon

Answer:

2.2 tons

Step-by-step explanation:

1 pound = 0.0005 tons

You have to multiply 4400 pounds by 0.0005 to get tons:

4400(0.0005) = 2.2 tons

Answer:

2.2 Tons

Step-by-step explanation:

You just have to see how many tons is in 4,400 pounds.

Answer:

The alternative hypothesis is; Hₐ;

[tex]\hat p[/tex] > 60%

Step-by-step explanation:

The given hypothesis of the number of Americans that vote in the presidential election is;

Hypothesis; At most 60% of Americans vote in the presidential elections

Therefore, the hypothesis states that the percentage of Americans that vote in the presidential ≤ 60%

The given hypothesis is the null hypothesis due to the presence of one of the operators ≤, ≥, or =

The null hypothesis is therefore, H₀: [tex]\hat p[/tex] ≤ 60%

Therefore, the alternative hypothesis is; Hₐ; [tex]\hat p[/tex] > 60%.
