Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.

We would solve this using direct proportion.

y = kx.

12.15 = 11.25k

k = 12.15 / 11.25

k = 1.08

Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.

y = kx.

59.13 = 54.75k

k = 59.13 / 54.75

k = 1.08

The equation that models the relationship will be:

y = 1.08x

Where does the length of day remain the same throughout the year?
djyliett [7]
Due to the inclination of the terrestrial axis, the day has different duration in several points of the planet, which also depends on the time of year. However, this duration remains the same throughout the year in the Equator, which is known as the imaginary line that divides the planet in two hemispheres: Northern Hemisphere and Southern Hemisphere.

You don't even have to look up the definition of 'standard deviation'.  You only
have to remember that 'smaller standard deviation' means 'less spread-out'.

First, let's find the mean (average).  It's not supposed to change:

1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .

Now, just pick 7 scores that total 561 and are all bunched up.

The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.

Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .

Answer:

  • vertical stretch: the function value (f) is multiplied by the stretch factor
  • horizontal stretch: the variable (x) is divided by the stretch factor

Step-by-step explanation:

A stretch can be vertical, horizontal, or both.

Multiplying the function value by a factor greater than 1 will stretch the graph vertically.

Dividing the variable value by a factor greater than 1 will stretch the graph horizontally.

__

The graph is stretched by the factor according to how it is applied.
