Answer:

The intercepts are -5 and 2

Step-by-step explanation:

Using the zero product property

f(x)=(x+5)(x-2)

0 =(x+5)(x-2)

0 = (x+5)   0=(x-2)

x = -5            x = 2

The intercepts are -5 and 2

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

if you simplify. 42/48.  7/8

if you simplify 14/16  is 7/8   So they are equal

If Joe worked 42 hours and packed 48 cartons and Bob worked 14 hours and packed 16 cartons, Joe and Bob worked at the same rate.

To determine if Joe and Bob worked at the same rate, we need to compare the number of cartons they packed per hour. We can calculate the rate by dividing the number of cartons packed by the number of hours worked.

For Joe:

Rate = Number of cartons packed / Number of hours worked

Rate = 48 cartons / 42 hours ≈ 1.143 cartons per hour

For Bob:

Rate = Number of cartons packed / Number of hours worked

Rate = 16 cartons / 14 hours ≈ 1.143 cartons per hour

Both Joe and Bob have a packing rate of approximately 1.143 cartons per hour.

They packed almost the same number of cartons per hour on average. This indicates that their packing efficiency is similar, regardless of the difference in the total number of hours or cartons packed.

Don't quote me on this but I think the answer is C. 0.27

The required approximate value of the relative frequency of students with green eyes is 0.27. Option C is correct.

From the sample population of students with blond hair, the approximate value of the relative frequency of students with green eyes is to be determined.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Number of students having green eyes with blond hair =21
Total number of students having blond hair = 78
relative frequency of students with green eyes = 21/78
                                                                                 = 0.27

Thus, the required approximate value of the relative frequency of students with green eyes is 0.27.

10^2 = 100

okay, now we plug these into the equation

36 + 64 = 100

so yes, it is a right triangle.

Answer:the answer is 02

Step-by-step explanation:

The solution is, c. 2, is the position of the car.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Explanation:

Before solving the problem, we should understand what is the length that corresponds to one notch in the graph.

We see that there are 3 notches between 0 and 6, and that the length of the notches is constant: so, each notch corresponds to the same length. Since we have 3 notches, the length of each notch is

6/3 = 2

now, we have,

Since the car is located at the first notch, it means that its position is:

x = 1*2 = 2

Hence, The solution is, c. 2, is the position of the car.

The mean absolute deviation (MAD) of her Math scores would be 1.2.

Step-by-step explanation:

Mean: 5.4 + 6.4 + 7.8 + 8.8 = 28.4/4 = 7.1

7.1 - 5.4 = 1.7

7.1 - 6.4 = 0.7

7.1 - 7.8 = 0.7

7.1 - 8.8 = 1.7

Mean Absolute Deviation: 1.7 + 0.7 + 0.7 + 1.7 = 4.8/4 = 1.2

Z = -3.57

Answer:

It means two lines intersected.

C is correct

Hope this helps!

:)

If a system of linear equations has one solution, this means that the lines are intersecting lines

Intersecting lines are lines that meet at a point.

For parallel lines, they do not meet at any point. Hence the system of equation formed by these lines does not have a solution

For two intersecting lines, the equation of both lines can be equated to get the unknown variable. This unknown variable will serve as the solution to the system of equation

Hence If a system of linear equations has one solution, this means that the lines are intersecting lines

Answer:

A) y = 1.875x + 1.25

B) 35 pounds

Step-by-step explanation:

A) We need two points to define a line. To find an equation that would describe the line of best fit, we can use one of the first points and one of the last points. Let's use (2, 5) and (10, 20).

General equation of a line:

y = mx + b

Slope of the line:

m = (20 - 5)/(10 - 2) = 1.875

y-intercept is found replacing a known point and the slope into the general  equation:

5 = 1.875*2 + b

b = 5 - 1.875*2 = 1.25

The final equation is:

y = 1.875x + 1.25

where y represents weight (in pounds) and x represents age (in months)

B) At x = 18:

y = 1.875*18 + 1.25 = 35
