Answer:

8 cookies left to be baked.

Step-by-step explanation:

Together both of them bakes = (1/3) + (2/5)

                                                 =  \frac{5}{15} +\frac{6}{15}

                                                 = \frac{11}{15} cookies.

So they have baked: (11/15) * 30 = 22 cookies together.

cookies left to be baked: 30 - 22 = 8 cookies.

The table of values shows the height of a car of a Ferris wheel as it travels in a circular motion. Which statements are true? S
Mashutka [201]

Answer:

The true statements are;

The car makes one complete revolution in 12 s

The radius of the Ferris wheel is 25 yd

Step-by-step explanation:

The values of the table of the given Ferris wheel are presented here as follows;

\begin{array}{cc}Time \ (seconds) &Height \ (yards)\\0&30\\3&55\\6&30\\9&5\\12&30\\15&55\\18&30\\21&5\\24&30\end{array}

From the table, we have;

The time it takes the Ferris wheel to complete a motion round from a height of 30 yards and back to 30 yards which is one revolution = 12 s

∴ The time it takes the car to complete one revolution = 12 s

The maximum height of the Ferris wheel = 55 yards

The lowest height of the Ferris wheel = 5 yards

The time at which the Ferris wheel is at the lowest height = 9 s, and 21 s

If the car is loaded at 0 s, then people are loaded above the lowest height of the Ferris wheel

The diameter of the Ferris wheel = The maximum height of the Ferris wheel - The minimum height of the Ferris wheel

∴ The diameter of the Ferris wheel = 55 yards - 5 yards = 50 yards

The radius of the Ferris wheel, R = 1/2 × The diameter of the Ferris wheel

∴ The radius of the Ferris wheel, R = 1/2 × 50 yards = 25 yards

Therefore, the true statements are;

The car makes one complete revolution in 12 s

The radius of the Ferris wheel is 25 yd.

yanalaym [24]
P(r successes in n trials) = ⁿC_{r}×[P(Success)^{r}]×[P(failure)]^{n-r}

We have
n=8
r=2
P(Success)=0.15
P(Failure)=0.85

Substitute these values into the formula, we have
P( 2 success in 8 trials) = ⁸C₂ × (0.15)² × (0.85)⁶
P( 2 success in 8 trials) = 0.2376.... ≈ 0.24 = 24%
