Answer:

The slope is 1/2

Step-by-step explanation:

The slope of an equation is rise over run (going from left to right). So, to get the answer you just need to start at the bottom point go up 1 and over 2 to get a slope of 1/2

What is the slope of a line that passes through (6,4) and (-1, 3)

pshichka [43]

Answer:

C) 1/7

Step-by-step explanation:

so idk what the formula is called but it looks like this:

y2-y1/x2-x1 and if you plug in the numbers then you'll get the answer

3 - 4/-1 - 6 = -1/-7 = 1/7

you can also switch the numbers your answer will always be the same

4 - 3/6 - (-1) = 1/7

so the answer is c

Ed and Taylor work together on a group quiz that has 20 multiple-choice questions, each with four choices for the possible answe

MissTica

Answer:

a. p = 0.25

b. n = 10, p = 0.25.

c. n = 10, p = 0.25.

d. n = 20, p = 0.25.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

a. For any single question on the quiz, what is p = chance of a correct guess?

4 options, 1 of which is correct. So

$p = \frac{1}{4} = 0.25$

So p = 0.25.

b. Let X = number of correct guesses that Isabelle makes. What are the values of n and p for the binomial distribution that describes X?

Should be Ed here.

Ed guesses answers for the first 10 questions

This means that $n = 10$ .

p is the same, so n = 10, p = 0.25.

c. Let Y = number of correct guesses that Taylor makes. What are the values of n and p for the binomial distribution that describes Y?

10 question, so $n = 10$ , p is the same.

d. Consider X + Y = total correct guesses that Isabelle and Taylor make. What are the values of n and p for the binomial distribution that describes X + Y?

20 questions, so $n = 20$

10 for Ed, with 0.25 probability, 10 for Taylor, with 0.25 probability. So

$p = \frac{10}{20}*0.25 + \frac{10}{20}*0.25 = 0.125 + 0.125 = 0.25$

So n = 20, p = 0.25.

A retail shop is replacing their flooring with laminate wood. The floor plan is shown below. Determine the total square feet of

Phantasy [73]

<h3>Answer: 1075 square feet</h3>

===========================================================

Explanation:

As shown in the diagram below, I've drawn a blue horizontal line to split the figure into two rectangles (smaller one up top, larger down below).

The smaller rectangle up top is 25 ft by 8 ft, giving an area of 25*8 = 200 sq ft.

The larger rectangle down below is 35 ft by 25 ft so we have an area of 35*25 = 875 sq ft.

The total area is 200+875 = 1075 square feet

Notes:

We can write "square feet" as "sq ft" or as "ft^2" without quotes.
The portion "5 ft", in the upper left corner, is never used.
