7 0

Step-by-step explanation:

Substitute x with -10 and y with 5.

(5) = 1.2(10) - 7

5 = 12 - 7

This is obviously true, so the graph indeed passes through the point (-10, 5).

The area of the regular hexagon is 169.74 ft2. A regular hexagon has an apothem with length 7 feet and an area of 169.74 feet sq

lorasvet [3.4K]

Answer:

The perimeter of the hexagon is 48.5 feet

Step-by-step explanation:

In this question, we are asked to calculate the perimeter of a regular hexagon, given the length of its apothem and its area value

Recall;

Mathematically the area of a regular hexagon A = 1/2 * P * a

where P is the perimeter of the hexagon which is unknown according to the question, a is the apothem of the hexagon which is 7 feet and A is the area which is 169.74 sq.feet according to the question

Plugging these values into the equation, we have;

169.74 = 0.5 * 7 * P

P = 169.74/3.5

P = 48.50 ft

A sample of 2,000 licensed drivers revealed the following number of speeding violations. Number of Violations Number of Drivers

Arturiano [62]

Answer:

The probability that a particular driver had exactly two speeding violations is 0.009.

Step-by-step explanation:

We are given that a sample of 2,000 licensed drivers revealed the following number of speeding violations;

Number of Violations Number of Drivers

0 1,910

1 46

2 18

3 12

4 9

5 or more 5

Total 2000

Now, the data means that 1,910 drivers had 0 speeding violations and so on.

Now, we have to find the probability that a particular driver had exactly two speeding violations, that means;

Number of drivers having exactly two speeding violations = 18

Total numbers of drivers = 2000

So, the required probability = $\frac{\text{No. of drivers having two speeding violations}}{\text{Total no. of drivers}}$

= $\frac{18}{2000}$ = 0.009

10.5x = 7.5x + 30
10.5x - 7.5x = 30
3x = 30
x = 30/3
x = 10

10.5(10) = 105
7.5(10) + 30 = 75 + 30 = 105

they need to purchase 10 t-shirts from each company for a total of $105 for each company
