Answer:

y=-4x

Step-by-step explanation:

First, out it into y=mx+b. Then find the slope(m). insert slope and one set of coordinates into equation and solve for y-intercept (b). Then you have your answer.

Answer:

y = 1x + 10

Step-by-step explanation:

y2 - y1 / x2 - x1

2 - 8 / -8 - (-2)

-6/ -6

y = 1x + b

2 = 1(-8) + b

2 = -8 + b

10 = b

The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports a

harina [27]

Answer:

$80 billion

Step-by-step explanation:

From the graph, we have the following:

$United\ States = -110$

$Denmark = -30$

$China = 120$

$Germany = 40$

$Spain = 30$

Required

Determine the difference in US and Denmark exports

The difference is calculated as thus:

$Difference = Denmark - United\ States$

This gives:

$Difference = -30 - (-110)$

$Difference = -30 +110$

$Difference = 80$

Hence, the difference is $80 billion

A sanitation supervisor is interested in testing to see if the mean amount of garbage per bin is different from 50. In a random

frez [133]

Answer: $H_0 : \mu=50\\\\ H_1 : \mu\neq50$

Step-by-step explanation:

An null hypothesis ( $H_0$ ) is a statement of equality which shows that there is no statistical difference between the groups being tested.

An alternative hypothesis ( $H_1$ ) is a statement of inequality which shows that there is statistical difference between the groups being tested.

Let $\mu$ be the population mean amount of garbage per bin .

Given : A sanitation supervisor is interested in testing to see if the mean amount of garbage per bin is different from 50.

i.e. $\mu\neq 50$ → Alternative

Thus , the appropriate null and alternative hypotheses :

$H_0 : \mu=50\\\\ H_1 : \mu\neq50$
