The amount spent by customers at a grocery store is normally distributed with a mean of $144.05 and a standard deviation of $34.52.

Approximately what percent of customers at the grocery store spend more than $200?


5.3%

8.2%

91.8%

94.7%

Answer:

4

Step-by-step explanation:

Given data

Number of student= 3

Total amount= 12000

Ratio= 6:5:x

Combined ratio= 6+5+x= 11+x

Applying the part to all method

if student number 2 got sh 4000

then

5/11+x= 4000/12000

5/11+x= 1/3

cross multiply

11+x= 15

x= 15-11

x= 4

Hence the value of x is 4

Answer:

x = 1

Step-by-step explanation:

For a quadratic function [tex]f(x)=ax^2+bx+c[/tex], the axis of symmetry is

[tex]x=-\frac{b}{2a}[/tex].

This comes from using part of the Quadratic Formula for finding zeros of the function:

[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} = \frac{-b}{2a} \pm \frac{\sqrt{b^2-4ac}}{2a}[/tex]

See the -b/(2a) in the first term?  That's the x-coordinate of the vertex (turning point) of the parabolic graph of the function.  The axis of symmetry goes through the vertex.

Answer:

Step-by-step explanation:

If you split up the 4 triangles you would have 8 right triangles

To solve for 1 right triangle you use the formula : 1/2 • l • h

1/2 • 1 • 2 = 1

Since there’s 8 right triangles you do:

8 • 1 = 8

Now the inner shape (a square):

2 • 2 = 4

Add up the areas:

8 + 4 = 12

Answer:

1st option

Step-by-step explanation:

From the graph the zeros are x = - 3 and x = 1 , then the corresponding factors are

(x + 3) and (x - 1) , so

y = a(x + 3)(x - 1) ← a is a multiplier

To find a substitute a point on the graph into the equation

Using (0, - 1.5 ) , then

- 1.5 = a(3)(- 1) = - 3a ( divide both sides by - 3 )

0.5 = a

Then

f(x) = 0.5(x + 3)(x - 1)

Answer:

the graph's slope-intercept is 3 or 3/1. you do this by finding the rise over run (how many squares does it go up, and how many does it go over).

The Y-intercept is -2. You can always find this by using the formula y= mx + b. Whatever number is in the place of "b" is the y-intercept.

I'm going to take a guess and say you're in Algebra 1. Either that or Pre-Algebra. This stuff took me a little while to full grasp, so don't worry! YOu'll understand it soon enough!

Answer:

30 cm

Step-by-step explanation:

For perimeter you just need to add all the outer sides.

6+6.5+4+4+9.5

Evaluate that and you get 30.

That's your answer.

(Remember perimeter is the value AROUND the figure.)

Answer:

x = 2, y = 0

Step-by-step explanation:

find y in terms of x:

8x - 4y = 16

4y = 8x - 16

y = 2x - 4

substitute y:

8x + 4y = 16

8x + 4(2x - 4) = 16

8x + 8x - 16 = 16

16x = 32

x = 2

find y:

8x + 4y = 16

16 + 4y = 16

y = 0

Answer:

17 months i think

Step-by-step explanation:

1867$-320$=1547

1547:91=17

The number of months Erica will be paying for the bike, if She made a $320 down payment and makes monthly payments of $91 is 17 months.

A formula known as an equation uses the equals sign to denote the equality of two expressions. It appears to be a mathematical expression on the left, an equal sign in the center, and a mathematical expression on the right.

Given:

The down payment = $320,

The amount of monthly installment = $91,

The total cost = $1867

Calculate the remaining amount after the down payment as shown below,

The remaining amount = The total cost - The down payment

The remaining amount = 1867 - 320

The remaining amount = $1547

Calculate the number of months as shown below,

The number of months  = The remaining amount  / The amount of monthly installment

The number of months  = 1547 / 91

The number of months  = 17 months

Answer:

259.8 square feet

Step-by-step explanation:

What is the area of a regular hexagon with sides that measure 10 feet and an

apothem that measures 8.66 feet?

The formula to solve the above question is given as:

Area = (3√3 s²)/ 2 where

s is the length of a side of the regular hexagon

Area of this Hexagon is calculated as:

= (3√3 × 10²)/2

= 3√3 × 100/2

= 259.80762114 square feet

Approximately = 259.8 square feet

The area of the regular hexagon = 259.8 square feet

Answer:

c = 77

b = 77

Step-by-step explanation:

c and b are equal because they are vertically opposite.

In addition, they both form a supplementary pair with 103 (but not at the same time).

c + 103 = 180                 c and 103 form a supplementary pair.

c = 180 - 103

c = 77

c = b = 77

Answer:

5a + 9b
