2 inches in length for ever inch in width. This is because the points are (1,2),(2,4),(3,6) and many more like that. Every x coordinate goes up by one while every y coordinate goes up by two. When you do the y coordinate divided by the x coordinate for all of them, you get two. Two is the constant of proportionality

Answer:

a). (5,30) (0,20)

b). (40,130) (35,120)

Step-by-step explanation:

a). (5,30) (0,20)

solid red line's solutions are all going to be going down and dashed blue line's solutions will be going up all solutions in those regions are considered solutions

b). (40,130) (35,120)

points are non-solutions because they are not in the shaded region for either line's solution .

haven't done this in a hot minute so im not sure 100%

Assume that it is true that people can not tell the difference between Coke and Pepsi. If a sample of 15 people participated in

pantera1 [17]

Answer:

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they can tell the difference between Coke and pepsi, or they cannot. The probability that a person has o telling the difference between Coke and pepsi is independent from each other. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to the normal distribution if

$np \geq 10$

and

$n(1-p)\geq 10$

In this problem, we have that:

$n = 15$

First condition

$np \geq 10$

$15p \geq 10$

$p \geq \frac{10}{15}$

$p \geq \frac{2}{3}$

Second condition

$n(1-p) \geq 10$

$15(1-p) \geq 10$

$15 - 15p \geq 10$

$-15p \geq -5$

Multiplying by -1

$15p \leq 5$

$p \leq \frac{1}{3}$

p cannot be at the at the same time greather than 2/3 and lesser than 1/3. So we cannot assume that the sampling distribution of the proportion of people that correctly chose Pepsi is normal.

If m<3=135 find m<7 help please

olchik [2.2K]

Answer:

$\fbox{m∠7 = 135°}$

Step-by-step explanation:

Given a transversal that intersects a set of parallel lines, various angles are formed.

When given this situation in geometry, these angles have different names and statements (primarily theorems) which justify their relationship.

There are 8 primary types of possible angles of parallel lines including:

Alternate Interior
Alternate Exterior
Same-Side (Consecutive) Interior
Same-Side (Consecutive) Exterior
Corresponding Angles
Vertical Angles
Supplementary Angles
Linear Pair

________________________________

According to what is given in the problem, we know that:

m∠3 = 135°.

________________________________

To solve for m∠7, we must identify the relationship that ∠3 and ∠7 have.

________________________________

Here is the solution in proof form:

_______________

Statement | Reason

m∠3 = 135° | Given

m∠3 ≅ m∠5 | Vertical Angles

m∠5 ≅ m∠7 | Corresponding Angles Theorem

m∠3 ≅ m∠7 | Transitive Property of Equality

m∠7 = 135° | Definition of Congruent Angles
