The college bookstore tells prospective students that the average cost of its textbooks is $92 per book, with a standard deviati

on of $15. The engineering students think that the average cost of their books is higher than the average for all students. To test the bookstore’s claim against their alternative, the engineering students collect a random sample of size 45, and calculate x = $97.34.

Given that 35.8 x 4.23= 151.434<br>write down a division sum with an answer of 423.​
Nina [5.8K]

Answer:

  151434/358 = 423

Step-by-step explanation:

Every product with non-zero factors can be written as an equivalent division relation.

  a·b = c   ⇒   a = c/b

Here, we have 35.8 × 4.23 = 151.434. This can be written as the equivalent ...

  4.23 = 151.434/35.8

We can multiply this by 100 to get a division relation with a quotient of 423:

  423 = 15143.4/35.8

If we want, we can move the decimal points another place to the right to get ...

  151434/358 = 423

Which transformations have been performed on the graph of f(x) =<img src="https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D" id="Tex
Nookie1986 [14]

Answer:

(B) compress the graph closer to the x-axis

(E) translate the graph to the left

(F) translate the graph up

Step-by-step explanation:

When functions are transformed there are a few simple rules:

  • Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
  • Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
  • Multiplying the function by a number less than 1 compresses it towards the x-axis.
  • Multiplying the function by a number greater than 1 stretches it away from the x-axis.

This graph has been multiplied by 1/4 which is less than 1. It will be compressed.

This graph has x added to by 3. It will shift left 3 units.

This graph has the output outside of x added to by 6. It will shift 6 units up. See picture below. The original function is red. The new function is blue.
