There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.

Answer :

The probability of selecting a red car off the lot is 0.231.
Step-by-step explanation:
Given:
Number of white cars = 25
Number of blue cars = 15
Number of red cars = 21
Number of black cars = 30
We need to find the probability of selecting a red car off the lot.
Solution:
First we will find the Total number of cars in the lot.
Now we can say that;
Total number of cars in the lot is equal to sum of Number of white cars and Number of blue cars and Number of red cars and Number of black cars.
framing in equation form we get;
Total number of cars in the lot =
Now to find the probability of selecting a red car off the lot we will divide Number of red cars by Total number of cars in the lot.
framing in equation form we get;
P(red) =
Rounding to three decimals we get;
P(red) = 0.231
Hence The probability of selecting a red car off the lot is 0.231.

BaLLatris [955]
Because this is a two-way table, the answer would be that 166 people were polled in total. Why? Well, there are lots of corresponding patterns leading up to this answer. We can easily find the answer by looking at the problem two different ways:

1st way: Identifying the missing solution by rows.

27 + 21 = 48 and 42 + 76 = 118, so we can find the missing value by adding 69 and 97 to get 166.

2nd way: Identifying the missing solution by columns.

27 + 42 = 69 and 21 + 76 = 97, so we can find the missing value by adding 48 and 118 to get 166, our missing solution.

Your final answer: 166 people were polled. Your answer would be D. If you need to better understand this, let me know and I will gladly assist you.

The angle of depression from the top of a lighthouse to a boat is 27*. if the direct distance from the top of lighthouse to the
alisha [4.7K]

Answer:

Correct answer:  Db = 411 .18 ft

Step-by-step explanation:

Given:

α = 27°  angle of depression

Dt = 462 ft  distance from the top of lighthouse to the boat

Db = ?   distance from the base of the lighthouse to the boat

Here we have a right triangle with hypotenuse Dt and one leg Db.

By definition

cos α = Db / Dt  ⇒ Db = Dt · cos α

Db = 462 · cos 27° = 462 · 0.89 = 411 .18 ft

Db = 411 .18 ft

Find the value of y if B is between A and C, AB is 2y, BC is 6y, and AC is 48.
Len [333]

Answer:

7. C. 6

8. H. √34

9. A. (1, 3.5)

10. J. 10

Step-by-step explanation:

7. AB = 2y, BC = 6y, AC = 48

AB + BC = AC (segment addition theorem)

Substitute the above values into the equation

2y + 6y = 48

Solve for y

8y = 48

Divide both sides by 8

8y/8 = 48/8

y = 6

8. Distance between P(2, 8) and Q(5, 3):

PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

P(2, 8) = (x_1, y_1)

Q(5, 3) = (x_2, y_2)

PQ = \sqrt{(5 - 2)^2 + (3 - 8)^2}

PQ = \sqrt{(3)^2 + (-5)^2}

PQ = \sqrt{9 + 25}

PQ = \sqrt{34}

9. Midpoint (M) of segment LB, for L(8, 5) and B(-6, 2) is given as:

M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})

Let L(8, 5) = (x_1, y_1)

B(-6, 2) = (x_2, y_2)

Thus:

M(\frac{8 + (-6)}{2}, \frac{5 + 2}{2})

M(\frac{2}{2}, \frac{7}{2})

M(1, 3.5)

10. M = -10, N = -20

Distance between M and N, MN = |-20 - (-10)|

= |-20 + 10| = |-10|

MN = 10
