**Answer 1**

Answer:

Option 4 is correct

Step-by-step explanation:

Here, we want to select from the options, the dataset that is represented on the histogram

From what we have in the question, there is a range from 60 to 100

Also, there are no terms between 70 and 80

option 1 is wrong as we can see terms between 70 and 80

option 2 is also wrong for this reason

option 3 is incorrect ; looking at the frequency, the numbers between 60 and 70 should be 5 only and we have 6 in that set

Option 4 is the correct answer

A road is made in such a way that the center of the road is higher off the ground than the sides of the road, in order to allow rainwater to drain. A cross-section of the road can be represented on a graph using the function f(x) = (x – 16)(x + 16), where x represents the distance from the center of the road, in feet. Rounded to the nearest tenth, what is the maximum height of the road, in feet?

### Answers

**Answer:**

45°

**Step-by-step explanation:**

The sum of interior angles in a triangle is equal to 180°

60 + x + 87 + x + 57 = 180 add like terms

2x + 204 = 180 subtract 204 from both sides

2x = -24 divide both sides by 2

x = -12

angle A is x + 57 so if we replace A with the value we found

(-12) + 57 = 45°

[tex]\$1.75[/tex]

**Step-by-step explanation:**

Total amount paid for the nuts is $19.60

Total amount paid for the ribbons is $11.20

Profit made on each jar is 98￠= $0.98

Cost price of the nuts and ribbon for the 40 jars is [tex]19.6+11.2=\$30.8[/tex]

Cost price for nuts and ribbonn for one jar = [tex]\dfrac{30.8}{40}=\$0.77[/tex]

Selling price is the sum of the cost price and profit.

Selling price for one jar = [tex]0.77+0.98=\$1.75[/tex]

Answer/Step-by-step explanation:

2. (2, -5) and (0, 5)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - (-5)}{0 - 2} = \frac{10}{-2} = -5 [/tex]

3. (-5, -5) and (-3, 5)

[tex] Slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 -(-5)}{-3 -(-5)} = \frac{10}{2} = 5 [/tex]

Write the equation of the line parallel to

y=-2/3x+4 and through the point (–3, 15)

### Answers

Parallel = same slope

y = -2/3x + b

Plug in point

15 = -2/3(-3) + b

15 = 2 + b, b = 13

Solution: y = -2/3x + 13

**Answer:**

y=-2/3x+17

**Step-by-step explanation:**

y=-2/3x+4

slope of that line is -2/3

y-y1=m(x-x1)

(-3,15)

y-15=-2/3(x-(-3))

y-15=-2/3x+2

y=-2/3x+17

Multiply both sides of the equation by 15, the least common multiple of 3,5.

Use the distributive property to multiply 5 by 2z−1.

Use the distributive property to multiply −3 by 3z+1.

Combine 10z and −9z to get z.

Subtract 3 from −5 to get −8.

Add 8 to both sides.

An artist has completed 1/14 of a painting in 2 weeks. At what rate is she working?

### Answers

**Answer:**

**Rate = 0.035 per weeks**

**Step-by-step explanation:**

Given that,

An artist has completed 1/14 of a painting in 2 weeks.

We need to find the rate at which she is working. Let the rate is R. It can be calculated by dividing part that is completed and time.

[tex]R=\dfrac{\dfrac{1}{14}}{2}\\\\R=0.035\ \text{per weeks}[/tex]
