Answer:

Total number of successes = 2400

Step-by-step explanation:

Probability of success of an event is given to be 0.4

⇒ p = 0.4

Also, Probability of failure = 1 - p

⇒ q = 1 - 0.4

⇒ q = 0.6

Also, Total number of trials = 6000

⇒ n = 6000

We need to find the total number of successes

So, Total number of successes = n × p

⇒ Total number of successes = 6000 × 0.4

⇒ Total number of successes = 2400

You should expect about 2400 successes because as a percent .4=40%

Slope Formula - (y² - y¹) / (x² - x¹)

(1, 7)

x¹ = 1

y¹ = 7

(-4, -8)

x² = -4

y² = -8

-8 - 7 = -15

-4 - 1 = -5

Simplify - -15/-5

-15/5 = -3

Your answer is -3.

Hope this Helps!!

Order least to greatest: -5, -8, 2, 0, 3, 1, -1
UkoKoshka [18]

-Least to greatest-

<h2>-8   -5   -1   0   1   2   3</h2>

The numbers that have a negative sign in front of them come first because they are less than 0. The other numbers can be ordered by what comes first. For example, 3 is bigger than 1 so 3 would come after 1.

Answer:

Step-by-step explanation:

12.

the formula for the volume of a cone is V=1/3hπr²

549.5 = 1/3(21)(3.14)(x)^2

549.5 = 7(3.14)(x)^2

549.5 = 21.98(x)^2

549.5 = 21.98(x)^2

divide by 21.98 on both sides

25 = (x)^2

sqrt 25 = sqrt x^2

5 = x

13.

the formula for the volume of a sphere is V=4/3πr^3

v=4/3(3.14)9^3

v=4/3(3.14)729

v=(4.186)729

v=3052.08

14.

the formula for the volume of a sphere is V=4/3πr^3

523=4/3(3.14)r^3

523=4/3(3.14)r^3

523=(4.186)r^3

divide by 4.186 on both sides

124.92=r^3

cube root on both sides

4.998=r

round

5=r
