At the end of the month, a restaurant manager used the total food sales for the month and the total number of customers for the month to calculate the mean about spent per customer during that month was $12.59. Is this value a statistical or a parameter? Explain.

Answer:

x=1, y=-2

Step-by-step explanation:

2x-3y=8 (1)                            

4x+3y=-2 (2)

From (1):

2x=8+3y

x=4+1.5y (3)

Subst (3) into (2)

4(4+1.5y)+3y=-2

16+6y+3y=-2

16+9y=-2

9y=-2-16

9y=-18

y=-2

subst y=2 in to (3)

x=4+(1.5*-2)

x=4-3

x=1

Ans: x=1, y=-2

6.08

Answer:

x=5 and x=-5

Step-by-step explanation:

1. first you would subtract 6 from both sides to set the equation = to zero.  

2. The equation would then be x^2-25=0.

3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0

4. by the zero product property, the roots are 5 and -5.

m5=75 degrees

m11=75 degrees

m16=65 degrees

To find 5, realize angles 5 and 8 equal 180, because they make up a straight line, line d.

180-105=75

To find 11, it is the same as finding 7. Just look at the similar sizes. Angle 7 is the same at angle 5, just turned around. There’s a term for this pair angles that I don’t remember now but it exists. Now, lines a and b are parallel, so their angles between lines that intersect both are the same too. This means, as angle 5 equals angle 7, angle 7 equals angle 11.

To find 16, we use a combination of the methods used in finding the previous angles.

180-115=65 degrees is angle 4

Angle 4=Angle 16

Knowing the two angles given and that lines a and b are parallel, you could find the measurements of every angle in each intersection if you wanted to.

Answer:

m5=75 degrees

m11=75 degrees

m16=65 degrees

Answer:

negative

Step-by-step explanation:

positive -> as x increases, y increases

negative -> as x increases, y decreases

Answer:

From left to right:

Negative, positive, none, nonlinear

1 is negative bc it has a negative slope

2 is positive because it has a positive slope

3 has no correlation because there is no pattern

4 is no linear because it’s not in a line, essentially. (This would be a parabola)

Answer:

The option on the top right.

Step-by-step explanation:

Because this is to be done asap, I will not take time to explain.

Answer:

Answer is the option in the top right

Step-by-step explanation:

The choice in the top right has a 4 x 4 base and the triangle has a height of 6 corresponding to the figure in the top.

Hi there!

[tex]\large\boxed{36 \text{ feet}}[/tex]

v = √2gh

Plug in the given velocity and acceleration due to gravity:

48 = √2(32)h

Square both sides:

2304 = 2(32)h

Simplify:

2304 = 64h

Divide both sides by 64:

h = 36 feet.

An exponent are a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2).

Answer:

3) 35.98

4) 63.98

Step-by-step explanation:

3) [(7+7)×3.14÷2]+14=35.98

4) (7+7)×3.14+14×3=63.98

Answer:

I take it that we solve for x and y, so we have

3x + y = 4, so we have y = 4 - 3x

and plug that in to

8x + 2y = 10

8x - 6x + 8 = 10

so

2x = 2

x = 1

y = 4 - 3

y = 1

Answer:

  610 m²

Step-by-step explanation:

If we extend the horizontal line across the right-hand portion of the figure, then the figure is divided into two rectangles:

  bottom: 5 m × 50 m = 250 m²

  top: 18 m × 20 m = 360 m²

The sum of these areas is the shaded area:

  shaded area = 250 m² +360 m² = 610 m²

Answer:

Yo

So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R

Step-by-step explanation:

So there ya go

D=R

and now bout the range ya gotta find the vertex, which is:

[tex] x = \frac{ - b}{2a} \: \: y = \frac{Δ}{4a} [/tex]

now pay attention

X=2/–2=–1

y=–(–1)²–2(–1)+3=4

Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]

Well, finally your answer is D

Step-by-step explanation:

Question 8

Let the equation of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

y = mx + b

Here, m = slope and y-intercept = b

Since, m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

For two points (1, 4) and (5, 8),

m = [tex]\frac{8-4}{5-1}[/tex]

m = 1

Equation will be,

y = (1)x + b

y = x + b

Since, this line passes through (1, 4),

4 = 1 + b

b = 3

Therefore, equation of the line will be,

y = x + 3

Question 9

Let the equation is y = mx + b

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

For two points (2, 10) and (6, 4)

m = [tex]\frac{10-4}{2-6}[/tex]

m = [tex]-\frac{3}{2}[/tex]

By substituting the value of 'm' in the equation,

y = [tex]-\frac{3}{2}x+b[/tex]

Since, this line passes through (2, 10)

10 = [tex]-\frac{3}{2}(2)+b[/tex]

b = 10 + 2

b = 12

Therefore, equation of the line will be,

[tex]y=-\frac{3}{2}x+12[/tex]

Answer:

m=2

b=1

Equation is y=2x+1
