Answer:

[tex]P(x \le -3) =0.30[/tex]

Step-by-step explanation:

Given

The attached probability distribution of x

Required

Find [tex]P(x \le -3)[/tex]

To do this, we consider all values of x less than or equal to-3.

So, we have:

[tex]P(x \le -3) =P(x=-5) + P(x = -3)[/tex]

From the table:

[tex]P(x=-5) = 0.17[/tex]

[tex]P(x = -3) = 0.13[/tex]

So, the equation becomes

[tex]P(x \le -3) =P(x=-5) + P(x = -3)[/tex]

[tex]P(x \le -3) =0.17 + 0.13[/tex]

[tex]P(x \le -3) =0.30[/tex]

Answer:

-25, 5

Step-by-step explanation:

-22 + -25 = -47

-25/5 minutes = -5

since there is no -5 in speed, then the answer is 5

I got it wrong and it told me negative 2 was the correct answer lol

Answer:

It gives you -7

Step-by-step explanation:

Think of the problem as 8 - 15, because 8 is a smaller number and 15 is bigger, you'll get a negative number.

The next step is use the rule**a-b = -(b-a)**which is - (15 - 8)

Then when you simplify it, it will be - (15 - 8)= - 7**(which is the answer)

Hope this helps:)

Answer:

d

Step-by-step explanation:

Answer:

15n

Step-by-step explanation:

Given

The above table

Required

The formula of the table

First, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{n_2 - n_1}[/tex]

Where:

n = Number of Lawns

y = Earnings

[tex](n_1,y_1) = (2,30)[/tex]

[tex](n_2,y_2) = (5,75)[/tex]

So, we have:

[tex]m = \frac{75 - 30}{5 - 2}[/tex]

[tex]m = \frac{45}{3}[/tex]

[tex]m = 15[/tex]

The equation is then calculated as:

[tex]y = m(n- n_1) + y_1[/tex]

This gives:

[tex]y = 15(n- 2) + 30[/tex]

[tex]y = 15n- 30 + 30[/tex]

[tex]y = 15n[/tex]

Hence:

B is correct

Answer:

The value of x is 7

Step-by-step explanation:

Complementary angles have a sum of 90°, therefore the equation to solve for x is:

∠1+∠2=90°

60°+5(x-1)°=90°

5(x-1)=30°

x-1=6

x=7

So the value of x is 7

Answer:

It does not absorb moisture, but does absorb oil; this quality makes polyester the perfect fabric for the application of water-, soil-, and fire-resistant finishes. Its low absorbency also makes it naturally resistant to stains.

Step-by-step explanation:

Polyester is what a call hydrophobic meaning it doesn’t absorb water. Even after washing it it’ll repel the clean water making still dirty.

Answer:

1/6 of a cup

Step-by-step explanation:

You're trying to figure out what 1/3 subtract 1/2 is, right?

Well first, convert both of them so they both have the same denominator.

Common Denominator = 6

So, 1/3 is 2/6 and 1/2 is 3/6 and 2/6 plus 3/6 is 5/6. Well, what's left in the cup? 6/6 subtract 5/6 is 1/6

Hope that helps!

[tex] 148 \frac{3}{4} \: {in}^{3} [/tex]

Step-by-step explanation:

volume of the right rectangular prism

[tex] = lwh \\ \\ = 10 \times 4 \frac{1}{4} \times 3 \frac{1}{2} \\ \\ = 10 \times \frac{17}{4} \times \frac{7}{2} \\ \\ = \frac{595}{4} \\ \\ = 148 \frac{3}{4} \: {in}^{3} [/tex]

Answer: The volume is 148 3/4 in3.

Step-by-step explanation:

V= l*w*h      

V= 10* 4 1/4* 3 1/2

V= 148 3/4

Answer:

Step-by-step explanation:

If you add up all the male and female categories, the total is 400

the number of females between 22 and 39 is 51

P(22 - 39)  = 51 / 400

P(22 - 39) = 0.1275

I think the answer you want is 51/400

Answer:

120 cm squared

Step-by-step explanation:

To find this is like finding a rectangle, you can take the triangular part of it and move it over to the side to become a rectangle

we can find the rectangle side by doing

21-6=15

then multiply it

15*8=120

Answer:

<Q = 30

Step-by-step explanation:

2x + 70 + x - 10 = 180

3x + 60 = 180

3x = 120

x = 40

x - 10

40 - 10

30

<Q = 30 because of vertical angles
