We first approach this problem by forming a diagram. Refer to the attachment.

You might notice a right triangle forming when you connect cities A, B, and C. In this case, we'll just need the Pythagorean theorem when solving for the distance between city B and city A.

AB^{2}=BC^{2}  + AC^{2}= 75^{2}  + 42^{2} =7389
AB=85.96

ANSWER: The distance between city B and city A is 85.96 kilometers.

Answer:

As per the statement:

Let  Event A represents the probability that a vehicle is white and Event B  represents the probability that it is a pick up truck .

then;

P(A) = 0.25 and P(B) = 0.15

It is also given that:

The Probability that it is a white pick up truck is 0.06.

⇒P(A \cap B) = 0.06 where A \cap B represents that it is white pick up truck.

We have to find the the probability that the vehicle is white {given that the vehicle is a pickup truck}

We use the formula:

P(A/B) = \frac{P(A \cap B)}{P(B)}

where

A/B represents that the pick up truck vehicle is white.

Substitute the given values we get;

P(A/B) = \frac{0.06}{0.15} = 0.4

Therefore,  the probability that the vehicle is white, given that the vehicle is a pickup truck is 0.4

The perimeter of the norwegian flag is 190 inches. What are the dimensions of the flag?
mario62 [17]
<span>The dimensions are 40 inches by 55 inches.

Explanation<span>:
We know that perimeter is the sum of all of the sides. Since this is rectangular, opposite sides are equal. This gives us
y+11/8y+y+11/8y=190.

Combining like terms, we have
2y+22/8y=190.

Writing 22/8 as a mixed number, we have
2y+2 3/4y=190
4 3/4y=190.

Divide both sides by 4 3/4:
(4 3/4y)</span></span>÷<span><span>(4 3/4)=190</span></span>÷<span><span>(4 3/4)
y=190</span></span>÷<span><span>(4 3/4).

Convert the mixed number to an improper fraction:
y=190</span></span>÷<span><span>(19/4).

To divide fractions, flip the second one and multiply:
 y=190*(4/19)=760/19=40.

Since y=40, 11/8y=11/8(40)=440/8=55.</span></span>

Answer:

  • g = -3/20s + 19

Step-by-step explanation:

Let's assume this is a function

<u>The points are</u>

  • (40, 13) and (60, 10)

<u>Since it is linear relation, we'll get the slope intercept form</u>

  • g = ms + b, where g- number of gallons, s- time in seconds, b- y intercept

<u>Using the points, let's calculate the formula</u>

  • m = (10 - 13)/(60 - 40) = -3/20
  • 10 = -3/20*60 + b
  • 10 = - 9 + b
  • b = 19

<u>So the formula is:</u>

  • g = -3/20s + 19
