Answer:
Step-by-step explanation:
- -2n +7 > -11
- -2n > -11 - 7
- -2n > -18
- n < -18/-2
- n < 9
- n = (-oo, 9)
Answer:Arrange the following measurements in order from smallest to largest.
0.35 kilogram, 5 gram, 9.4 gram
Step-by-step explanation:Kilograms (Kg) and grams (g) are both units of measurement for MASS quantity. However, these units are not the same as they vary in magnitude. The kilograms is bigger unit of measurement than the grams. 1000grams makes 1kilograms.
According to this question, 0.35 kilograms 9.4 grams and 5 grams are to be arranged in ascending order i.e. from smallest to largest. First, we need to change all the units to the same.
We change 0.35kg to g
Since 1000g = 1kg
Then, 0.35kg = 0.35 × 1000
= 350g.
Rearranging the values, we have:
5 grams < 9.4 grams < 0.35 kilograms

Answer:
0.2839 = 28.93%
Step-by-step explanation:
In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z
Le x be tons of coal in a car
Z = (x – mean)/standard deviation
Z = (x – μ)/ σ
P (x<68.5) = P(z < (68.5-69)/0.9)
P (x<68.5) = P(z < -0.5555)
Then we use the z table to find the area under the curve.
P (x<68.5) = 0.2893
