Answer:

m = 3/2

b = 0

y = 3/2x

Step-by-step explanation:

M is the slope, which is the rise/run of a line.

Using this, we know m is 3/2.

B is the y-intercept, which is where the line crosses the y-axis. In this case, B equals 0.

We use this information to put together our final equation of y= 3/2x (since B equals 0, there is no + or - after the slope)

Answer:x=0

Step-by-step explanation:

subtract 3 from both sides

3=3=x+3-5x-3

simplify

0=x-5x

switch sides

x-5x

add similar elements ; x-5x=-4x

-4x=0

divided both side by -4

-4x/-4 . = . 0/-4

Triangle ABC is similar to triangle DEF. The length of BC is 21cm. The length of DE is 10 cm. The length of EF is 14 cm. What is

Anarel [89]

It's a similar triangle so the ratios of corresponding sides should be equal which means

BC/EF = AB/DE
21/14 = AB/10
AB = 21/14 * 10 = 15 cm

A software company decided to conduct a survey on customer satisfaction. Out of 564 customers who participated in the online sur

nikklg [1K]

Answer:

$z=\frac{0.0904 -0.1}{\sqrt{\frac{0.1(1-0.1)}{564}}}=-0.760 \approx -0.8$

$p_v =2*P(z$

Step-by-step explanation:

Information given

n=564 represent the sample selected

X=51 represent the number of people who rated the overall services as poor

$\hat p=\frac{51}{564}=0.0904$ estimated proportion of people who rated the overall services as poor

$p_o=0.1$ is the value to compare

z would represent the statistic

Hypothsis to analyze

We want to analyze if the proportion of customers who would rate the overall car rental services as poor is 0.1, so then the system of hypothesis are:

Null hypothesis: $p=0.1$

Alternative hypothesis: $p \neq 0.1$

The statistic for a one z test for a proportion is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

Replacing the info given we got:

$z=\frac{0.0904 -0.1}{\sqrt{\frac{0.1(1-0.1)}{564}}}=-0.760 \approx -0.8$

And the p value since we have a bilateral test is given b:

$p_v =2*P(z$
