Reika [66]

Answer:

74.7 km/h

Step-by-step explanation:

The computation of the average speed is shown below:

As we know that

Speed = Distance ÷ Time

where

Distance = 66 km

And, the time is from 14.54 to 15.47 is 53 minutes

So, the speed is

= 66 km ÷ 53 minutes

= 74.71698 kilometers per hour

= 74.7 km/h

The amount of radioactive uranium changes with time. The table below shows the amount of radioactive uranium f(t) left after tim

aniked [119]

Answer:

$f(t) = 100(0.25)^t$

Step-by-step explanation:

The general exponential function is,

$f(t)=ab^t$

The points given in the table are,

$(0,100),(0.5,50),(1,25)$

Putting $(0,100),(1,25)$ in the general equation, we get

$\Rightarrow 100=ab^0$

$\Rightarrow a=100$

And

$\Rightarrow 25=ab^{1}$

$\Rightarrow ab=25$

Putting the value of a,

$\Rightarrow 100b=25$

$\Rightarrow b=0.25$

Now the exponential function becomes,

$f(t) = 100(0.25)^t$

The faces of an eight-sided solid are labeled 1 through 8. Each

Elenna [48]

Answer:

The probability that an odd number is rolled on both solids is $\frac{1}{4}$ .

Step-by-step explanation:

Consider the provided information.

For the 8 sided dice the total number of outcomes = 64.

The favourable outcomes i.e odd numbers on both the solid = 16

(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (1,7), (1,8)

(2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (2,7), (2,8)

(3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (3,7), (3,8)

(4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (4,7), (4,8)

(5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (5,7), (5,8)

(6,1), (6,2), (6,3), (6,4), (6,5), (6,6), (6,7), (6,8)

(7,1), (7,2), (7,3), (7,4), (7,5), (7,6), (7,7), (7,8)

(8,1), (8,2), (8,3), (8,4), (8,5), (8,6), (8,7), (8,8)

We know that $\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

$\text{Probability of odd on both solid}=\frac{16}{64}$

$\text{Probability of odd on both solid}=\frac{1}{4}$

Hence, the probability that an odd number is rolled on both solids is $\frac{1}{4}$ .

What is the greatest common factor for 130

3241004551 [841]

The greatest common factor for 130 would be 130.
Factors of 130
1, 2 , 5 ,10,13, 26, 65 and 130

A factor is a number <span>that is multiplied with another produces a given number or expression. Lets look at factors of 16</span>

1x16 = 16
2 x 8 = 16
The factors are 1,2,8,16. When we multiply them we get 16. Also each one of these factors divide into 16 evenly too.

A golf pro wants to determine if Titleist Pro V1 golf balls (1) travel farther, on average, than Callaway Chrome Soft golf balls

Greeley [361]

Complete options are;

A) Paired t-test for means

B) Paired Z-test for means

C) Z-test for proportion

D) t-test for means

E) Z-test for means

F) t-test for proportion

Answer:

B) Paired Z-test for means

Step-by-step explanation:

We are told that the distances travelled are normally distributed.

We are also trying to find out if the average distance travelled by the Titleist Pro V1 golf balls is farther than that of the Callaway Chrome Soft golf balls.

Also, the standard deviation of both cases are known.

Thus, this is where Paired Z-test for means is used.
