Answer:

8, or 4 and 2

Step-by-step explanation:

5-2 = 3, and 8 times 3 = 24

It can also be 3 times 4 times 2 because 4 times 2 equals 8

What is the sum of the series?

Mamont248 [21]

Answer:

45

Step-by-step explanation:

Since the values are relatively small substitute i = 1 to 5 into 3i and sum

(3 × 1) + (3 × 2) + (3 × 3) + (3 × 4) + (3 × 5)

= 3 + 6 + 9 + 12 + 15

= 45

If the angle between each blade of the wind turbine is the same, and each blade has a length of 20 meters, find the distance bet

Ket [755]

A typical windmill has three blades. We can envision these blades in a circle, which a circle = 360 degrees. We want to divide up the angles of the blades so they are even or makes up 360 degrees. We have three blades so we have 3 angles to divide by 360 degrees. So, 360 / 3 = 120 degrees. Now that we know the angle of the blades, we can use the Law of Cos to solve the distance between the blade tip.

Law of Cos

$c^2 = a^2 + b^2 - 2(a)(b)(\cos A)$

We know

a = 20

b = 20

A = Angle = 120

We need to solve for c

$c^2 = a^2 + b^2 - 2(a)(b)(\cos A)$

Take the square root of each side of the =

$\sqrt{c^2} = \sqrt{a^2 + b^2 - 2(a)(b)(\cos A)}$

$c = \sqrt{a^2 + b^2 - 2(a)(b)(\cos A)}$

Input the values we know into the formula and solve for c:

$c = \sqrt{a^2 + b^2 - 2(a)(b)(\cos A)}$

$c = \sqrt{20^2 + 20^2 - 2(20)(20)(\cos 120)}$

$c = \sqrt{400 + 400 - 2(20)(20)(\cos 120)}$

$c = \sqrt{800 - 2(20)(20)(\cos 120)}$

$c = \sqrt{800 - 2(400)(\cos 120)}$

$c = \sqrt{800 - 800(\cos 120)}$

$c = \sqrt{800 - (-400)}$

$c = \sqrt{1200}$

$c = 20\sqrt{3}$

$c = 34.641016$

$c = 34.64$

We now have our answer, which is 34.64 and that is C.

Suppose Clay, a grocery store owner, is monitoring the rate at which customers enter his store. After watching customers enter f

Kitty [74]

Answer:

70th percentile for the amount of time between customers entering is 30.10

Step-by-step explanation:

given data

mean = 25

to find out

What is the 70th percentile for the amount of time between customers entering Clay's store

solution

we know that here mean is

mean = $\frac{1}{\lambda}$ ..................1

so here 25 = $\frac{1}{\lambda}$

and we consider time value corresponding to 70th percentile = x

so we can say

P(X < x) = 1 - $e^{- \lambda *x}$

P(X < x) = 70 %

1 - $e^{\frac{-x}{25}}$ = 70 %

1 - $e^{\frac{-x}{25} }$ = 0.70

$e^{\frac{- x}{25} }$ = 0.30

take ln both side

$\frac{-x}{25}$ = ln 0.30

$\frac{x}{25}$ = 1.203973

x = 30.10

70th percentile for the amount of time between customers entering is 30.10

Katrina is driving to her grandparents' house. The distance, y miles, she has left to go after driving for hours is given by f(x

emmasim [6.3K]

Answer:

Step-by-step explanation:

Jenna will complete remaining distance in 6 hours.

Since we know that . Let us find the rate at which Jenna traveled 100 miles.

Remaining distance is 400-100=300.

Now let us find the time Jenna will take to travel 300 miles.

Therefore, Jenna took 6 hours to complete remaining distance.
