Answer:

Robert is 10  and his dad is 40 years old

Step-by-step explanation:

We have (4x+5)=3(x+5)

4x+5=3x+15

x=10.

Roberts is 10 years old and his father is 40 years old.

Answer:

Step-by-step explanation:

Roberts's father=4x

Robert=x

After 5 years, the ages will be

4x+5 and x+5 because we just simply add 5 years to their ages

It says that the father will be 3x older. So,

3(x+5)=4x+5.   --this is the equation

3x+15=4x+5

    -5         -5

3x+10=4x

-3x     -3x

x=10

Im not so sure about this. I need help making a proof that is 9 steps long. (See image)
Leona [35]

Step-by-step explanation:

Not entirely sure, but I believe something like this:

∠1 + ∠2 = 180° since they are a linear pair;

Since ∠1  = ∠2, we can say:

∠1 + ∠1 = 180°

2(∠1) = 180°

∠1 = 90°

And since:

∠1 = ∠2

∠2 = 90°

So the angle between t and s is 90°;

An angle of 90° means t and s are perpendicular (⊥)

A statistic is said to be unbiased if
xxMikexx [17]

Answer:

A statistic is said to be unbiased if the mean of its sampling distribution is equal to the true value of the parameter being estimated.

Step-by-step explanation:

A parameter is a number that describes the population.  

A statistic is a number that describes a sample.  

A statistic used to estimate a parameter is unbiased if the mean of its sampling distribution is exactly equal to the true value of the parameter being estimated. For example, the mean of a sample is an unbiased estimate of the mean of the population from which the sample was drawn.

A statistic is biased if its expected value is not equal to the parameter.

A comet travels at an average speed of 233,000 km/h.
mixer [17]

Answer:

39,144,000 km

Step-by-step explanation:

Hi there!

Distance traveled = time * speed

Given speed: 233000 km/h

Given time: 7 days

It's important to note that our speed is given in per hours and out time is given in days. So in order to find how far the comet has traveled we must convert days to hours.

There are 24 hours in 1 day.

So to convert days to hours simply multiply amount of days by 24

24 * 7 = 168

So the comet has traveled for 168 hours

Now we can find distance traveled

Once again distance traveled = time * speed

Given speed is 233000 km/h

Given time is 168 hours

Distance = 168 * 233000 = 39,144,000

So the comet has traveled for a total distance of 39,144,000 km
