Answer: y=(-1/4)x

Step-by-step explanation:

slope-intercept form: y=ax+b

--------------------------------------------

#1 Find the slope

- Use rise/run: -(2/8)=-1/4

-Use slope formula: (2-0)/(-8-0)=2/-8=-1/4

#2 Find the y-intercept

- Given the point (0,0), the y-intercept is already shown which is 0

------------------------------------------

a=-1/4

b=0

y=(-1/4)x

Find the area of the triangle...
Alekssandra [29.7K]
In order to find height (h), tan20 = h/26
h = 26 \tan(20)  = 9.46
Now for the left part of base (b1), where b2 = 26 and entire base (b) = b1+b2
\tan(36) =  h \div b1  \\ b1 = 9.46 \div  \tan(36)  = 13.03
So b = 13.03+26 = 39.03

Now Area (A) = 1/2bh = 1/2 (39.03)(9.46)
A = 184.59

ser-zykov [4K]

Answer:

Step-by-step explanation:

Let X represent for males and Y for females

Given that

Group   Group One     Group Two  

Mean 84.00          78.00

SD        4.00                    8.00

SEM 1.26             2.53

N            10              10  

SEM is calculated as \frac{s}{\sqrt{n} } for each group

H_0: \bar x = \bar y\\H_a: \bar x \neq \bar y

(Two tailed test at 5% significance level)

t = 2.1213\\  df = 18\\  standard error of difference = 2.828\\p=0.0480

Since p <0.05 we reject H0 and there is significant difference between the groups.

A.Exam scores were significantly higher in the male group, t(18) = 2.83, p < .05B

A bag contains 7 red marbles, 5 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probabi
Korvikt [17]

Answer:

<h3>0.063</h3><h2>Step-by-step explanation:</h2>

<h3>probability is defined as the measure of chances of events happening or chances of occurrence.The probability that an event can happen is zero(0)</h3><h3>Probability can be calculated using the formular: number of required outcome all over number of total possible outcome.</h3>

Probability of 3 red = 7/16 x 6/15 x 5/14 = (7)(6)(5)/(16)(15)(14)=

6x5/16x15x2 = 5/16x5= 1/16 = (1/2)(.125) = 0.0625

Probability of 3 reds = 0.0625

round off to thousandths Pr(3R) = 0.063
