Mathematics
1 answer:
lys-0071 [83]4 years ago
4 0

Answer:

1. D) -30

2. B) -33

3. A) 600

Step-by-step explanation:

1. This answer would be D) -30 because the statement is saying that Keith <u><em>lost </em></u> 30 lbs, and losing something would be a negative

2. This answer would be B) -33 because just like in the first question, something is decreasing or falling. In this case, it's the temperature that is falling.

3. This answer would be A) 600 because since Alice is already above the ground 100 feet, all you would do is add the 500 feet that she rose with (100 + 500). To rise would be to increase, or in this rate, stay positive.

There are 3 black marbles and 4 red marbles in a bag.
devlian [24]
3 + 4 = 7 all marables in bag
The probability that the first marable is black
P(A_1)=\dfrac{3}{7}
The probability that the second marable is black too
P(A_2)=\dfrac{2}{6}=\dfrac{1}{3}
Together:
P(A)=P(A_1)\cdot P(A_2)=\dfrac{3}{7}\cdot\dfrac{1}{3}=\dfrac{1}{7}\to D

Answer:

100 resident/km

Step-by-step explanation:

In order to find the population density, we have to calculate the area of the township first.

We know that:

L = length = 5 km

W = width = 4 km

So the area of the township is

A=L\cdot W = 5 \cdot 4 = 20 km^2A=L⋅W=5⋅4=20km

2

Now we can find the population density by using

d=\frac{N}{A}d=

A

N

where N is the number of residents, and A is the area.

Substituting N = 2000, we find:

d=\frac{2000}{20}=100 res./km^2d=

20

2000

=100res./km

2

so, 100 residents per kilometer squared
