Suppose the given coordinates are represented as,

\begin{gathered} (x_1,y_1)=(4,2) \\ (x_2,y_2)=(7,6.5) \end{gathered}

Then, the formula for slope can be expressed as,

\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{6.5-2}{7-4} \end{gathered}

Solving it,

m=\frac{4.5}{3}=1.5

The slope is 1.5.

The formula of (10, 8) anjd (-5,8) is

m=\frac{8-8}{-5-10}

Simplify a - b - [C- (d - e) - f] - g).
dalvyx [7]

Answer:

a-b-C+d-e+f-g

Step-by-step explanation:

Steps

$a-b-\left(C-\left(d-e\right)-f\right)-g$

Show Steps

$-\left(d-e\right):\quad-d+e$

$=a-b-\left(C+e-d-f\right)-g$

Show Steps

$-\left(C-d+e-f\right):\quad-C+d-e+f$

$=a-b-C+d-e+f-g$

MA_775_DIABLO [31]

Answer:

Test statistic Z = p diff/std error = 2.3333

p value one tailed = 0.009815

Step-by-step explanation:

Given that in a survey conducted by a website, employers were asked if they had ever sent an employee home because they were dressed inappropriately.

Sample size n = 2755

Sample favourable x = 967

Sample proportion p = \frac{967}{2755} \\=0.3510

H_0: p = 0.3333\\H_a: p >0.3333

(right tailed test at 5% significance level)

p difference = 0.0210

Standard error assuming H0 is true is \sqrt{\frac{0.3333*0.6667}{2755} } \\=0.0090

Test statistic Z = p diff/std error = 2.3333

p value one tailed = 0.009815

Since p <0.05 we reject null hypothesis.

Write a unit rate for the situation. $1.98 for 6 bananas
USPshnik [31]
A unit rate is when you find a rate when one variable (or value) is equal to one.

Let's find the unit rate for the price of the bananas. 

1.98/6= 0.33

It is 33 cents for one banana. That is the unit rate. 

I hope this helps!

First you go on the computer and you know how there's always a FBI agent watching you? You tell the FBI agent that your stuck in a hole and you need help. Then the FBI agent will send their team to come and get you but it won't be so easy because why? The little old lady you ran over decided to get revenge and set up a trap. so now it's the FBI vs The little old lady

the FBI starts to shoot at the Old Lady but she moves so fast she like lighting then she goes to attack the FBI agent but then the FBI agent reveals himself as the her grandson! Apparently he was able to get away and survive her attack since this caught the old lady off guard the grandson smashes cookies into her face and help you out of the hole

your welcome
