Number of favourable outcomes = 5

Number of possible outcomes = 26

P(vowel) = 5/26

Answer: 5/26

I believe the answer would be 5/26
The reason is there are 5 vowels and 26 letters in the alphabet.

what does the slope of -1 tell you about thr relationship between lengths and widths of rectangles with perimeter 24?
NeX [460]

Using linear function concepts, the slope of -1 means that when one of the length/width is increased by 1, the other is decreased by 1.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem:

  • The lengths and the widths are interchangeable, that is, either can be considered as the input or as the output.
  • The slope of -1 means that when the input in increased by 1, the output is decreased by -1, that is, when one of the length/width is increased by 1, the other is decreased by 1.

The mass of a bag of potatoes is 860 kg round to the nearest 10kg. i) Give the upper and lower bounds for the mass.
MrMuchimi

Answer:

  • Lower bound ⇒ 855 kg
  • Upper bound ⇒ 865 kg

Step-by-step explanation:

The upper bound is the highest number that a figure can be to be rounded off to the rounded figure.

The lower bound is the lowest number that a figure can be to be rounded odd to the rounded figure.

The lower bound of 860 to the nearest 10 is;

= 855 kg

855 is the lowest figure that can be rounded up to 860.

The Upper bound is;

= 865

865 is the highest figure because no figure above this can be rounded to 860.

<em>855 kg ≤ 860 kg < 865 kg</em>

Part 1:
Vikentia [17]

Answer:

Part 1 : y = 0.75x

Part 2 : $750

Step-by-step explanation:

Part 1

Worst Buy, a local electronics store, advertises a sale price of 25% off all televisions 42" or bigger. Model the sales price (original price minus discount) of those televisions, y, as a function of the regular price of the tv, x.

Let y be the sales price of the tv and x its regular price. Since its sales price = regular price - discount, and our discount is 25% of the sales price, that is 0.25x, we have

sales price = regular price - discount

y = x - 0.25x

y = 0.75x

Part 2:  If the regular price of a 60" television is $1000, use the equation you came up with in part 1 to find the sales price of the item

Since the sales price, y = 0.75x,and x = regular price = $1000,

substituting x into y, we have

y = 0.75x

y = 0.75($1000)

y = $750
