Answer:

x = 3 - t and y = 4 - 2t

Step-by-step explanation:

We have to find such a set of parametric equations for the given equation which result in an x-value equal to 3 and a y-value equal to 4 when t is substituted as 0.

There can be more than 1 possible answers to this problem. You have to use hit and trial method to come up with the correct set of parametric equations. One of the possible set is:

y = 4 - 2t , x = 3 - t

For t = 0

x= 3 and y = 4

Hence, the condition is satisfied.

Now checking if these parametric equations result in given equation or not.

From second equation, we get:

t = 3 - x

Using this value in first equation, we get:

y = 4 - 2(3 - x)

y = 4 - 6 + 2x

y = 2x - 2

Which is the given equation.

Hence the set of parametric equation is:

x = 3 - t and y = 4 - 2t

HIJK is a parallelogram because the midpoint of both diagonals is __________, which means the diagonals bisect each other.
Ivanshal [37]

Answer:

HIJK is a parallelogram because the midpoint of both diagonals is unique and intersect each other, which means the diagonals bisect each other.

Step-by-step explanation:

We are given the following in the question.

HIJK is a parallelogram.

So it satisfies the property of parallelogram.

  • The diagonals of a parallelogram bisect each other.
  • That is the intersection of the diagonals of the parallelogram is unique and divide the diagonals in two equal parts each.

Thus,

HIJK is a parallelogram because the midpoint of both diagonals is unique and intersect, which means the diagonals bisect each other.

The price of a share of stock in JZMobile was $74 two weeks ago. Seven weeks ago, the price was $59 a share. Which linear equati
jok3333 [9.3K]

Given:

The price of a share of stock in JZMobile was $74 two weeks ago.

Seven weeks ago, the price was $59 a share.

To find:

The linear equation to find the price p of a share of JZMobile w weeks from now.

Solution:

Let, p be the price of a share of JZMobile w weeks from now.

The price of a share of stock in JZMobile was $74 two weeks ago. It means, the graph of linear equation passes through (2,74).

Seven weeks ago, the price was $59 a share. It means, the graph of linear equation passes through (7,59).

The graph of linear equation passes through two points (2,74) and (7,59). So, the linear equation is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-74=\dfrac{59-74}{7-2}(x-2)

y-74=\dfrac{-15}{5}(x-2)

y-74=-3(x-2)

y-74=-3x+6

Adding 74 on both sides, we get

y=-3x+6+74

y=-3x+80

y=80-3x

Therefore, the correct option is C.

What number line model represents the expression 2.5+4.5<br>Choose 1 answer: A, B, or C?<br><br>​
a_sh-v [17]

Answer:

A

Step-by-step explanation:

Because, the first point will be plotted at 2.5 (each line is 1 which means like line after 0 is 1, the next one is 2, and so one). When you add 2.5 with 4.5 it equals to 7 which means the next point will be placed at 7. (right behind 8)

A local retailer claims that the mean waiting time is less than 8 minutes. A random sample of 20 waiting times has a mean of 6.3
rusak2 [61]

Answer:

The claim is not true

Step-by-step explanation:

We are given that A local retailer claims that the mean waiting time is less than 8 minutes.

H_0:\mu=8

H_a:\mu

A random sample of 20 waiting times has a mean of 6.3 minutes with a standard deviation of 2.1 minutes.

\bar{x}=6.3

s = 2.1

n = 20

Since n <30 and population standard deviation is unknown

So,we will use t test

So,t=\frac{x-\mu}{\frac{s}{\sqrt{n}}}

t=\frac{6.3-8}{\frac{2.1}{\sqrt{20}}}

t=-3.62

α = 0.01

Degree of freedom = df=n-1=20-1=19

t_{df,\frac{\alpha}{2}}=t_{19,\frac{0.01}{2}}=2.861

t calculated < t critical

So, we failed to reject null hypothesis

Hence the claim is not true
