Averqge speed of the car = 45 miles/hr, which means,

The car travels 45 miles in 1 hr.

Using unitary method,

The car travels 45 miles in 1 hr

The car would travel 1 mile in 1/45 hrs

The car would travel 90 miles in 1/45×90 hrs

So, calculating this,

1/45×90 = 2 hrs

Answer:

actually this is physics

d=s×t

∴45×90⇒4050km

Sewage and industrial pollutants dumped into a body of water can reduce the dissolved oxygen concentration and adversely affect
MArishka [77]

Answer:

FALSE

Since 0.385 < 0.526, the value for week 3 is accepted.

Explanation:

Qexp = (|Xq - Xₙ₋₁|)/w

where Xq is the suspected outlier; Xₙ₋₁ is the next nearest data point; w is the range of data

First, the data are arranged in decreasing order, from highest to lowest:

3. 5.6

2. 5.1

8. 5.1

1. 4.9

6. 4.9

5. 4.7

7. 4.5

4. 4.3

Xq = 5.6; Xₙ₋₁ = 5.1; w = 5.6 - 4.3 = 1.3

Qexp = (|5.6 - 5.1|)/1.3 = 0.385

From tables, at 95% confidence level, for n = 8, Qcrit = 0.526

Since 0.385 < 0.526, the value for week 3 is accepted.

Four people weigh a standard mass of 10.00g on the same balance. Which of the following sets of readings suggests measurements t
Svetach [21]
An example of accurate but not precise would be 3 people weigh a 10g sample. the weights are 0g, 10g, & 20 grams. the scale is way off but the weights average to the right thing.
precise but not accurate would weighing a 10g sample 3 times and getting 5.5, 5.4, & 5.5. they'e all incredibly similar therefore precise but its nowhere near 10, so not accurate. 
neither precise nor accurate would be 3 weights being 10, 20, &30. It averages wrong and is imprecise.
