$1\%\ \ \rightarrow\ \ \frac{1}{100}=0.01 \\\\2.3\%\ \ \rightarrow\ \ x\\\\x= \frac{2.3\%\cdot0.01}{1\%} \ \ \ \Rightarrow\ \ \ x=0.023$

2.3% is the same thing as 0.023 .

Solve using gaussian elimination and show ur work

jarptica [38.1K]

Add the last two equations to eliminate x :

(x - 2y - 3z) + (- x + y + 2z) = 0 + 3

- y - z = 3

y + z = -3

Subtract this from the first equation to eliminate z, then solve for y :

(2y + z) - (y + z) = -8 - (-3)

y = -5

Plug this into the first equation to solve for z :

2(-5) + z = -8

z = 2

Plug both of these into either the second or third equations to solve for x :

x - 2(-5) - 3(2) = 0

x = -4

A food truck operator has traditionally sold 75 bowls of noodle soup each day. He moves to a new location and after a week sees

pashok25 [27]

Answer:

The p-value of the test is 0.031. How should he interpret the p-value as "There is a 96.9% chance that the true mean of soup sales at the new location is greater than 75 bowls a day"

Step-by-step explanation:

P-value"In statistical hypothesis testing, the p-value or probability value is the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct"

Two equations for the constant of proportionality equal to 1/2

NemiM [27]

y=kx and y= $\frac{k}{x}$ are two equations of constant of proportionality

Step-by-step explanation:

There are two equations for the constant of proportionality. That is

(i) Direct proportion

(ii) Inverse proportion

In direct proportion y=kx, Now

if x increases, then y also increases and if x decreases, then y also decreases. So, k is a constant proportionality.

In Inverse proportion y= $\frac{k}{x}$ , Now

if x increases then y decreases and if x decreases, then y increases and k is a constant proportionality.

In direct proportion, we put y=1 and x=2, So k= $\frac{1}{2}$ .

So, the equations y=kx and y= $\frac{k}{x}$ are two equations of constant of proportionality.

A ferryboat makes four trips to an island each day.The ferry can hold 88 people.If the ferry is full on each trip,how many passe

olga_2 [115]

Multiplication was invented to reduce the work involved in repeated addition.

... 88 + 88 + 88 + 88 = 4×88 = 352

352 passengers are carried to the island each day.

_____

Some questions must be answered before we can give a definite answer.

1. If the same person rides twice, are they counted twice?

2. Are passengers on the return trips (from the island) counted?

3. If return trip passengers are counted, is the ferry full on those trips?

4. Does every passenger to the island return the same day?

5. Does any passenger go to the island more than once per day?
