The segments AE, EC, AD and DB are in proportion.

Therefore we have the equation:

$\dfrac{CE}{BD}=\dfrac{AE}{AD}$

AE = 4ft, AD = 8ft and BD = 2ft. Substitute:

$\dfrac{CE}{2}=\dfrac{\not4^1}{\not8_2}$ <em>multiply both sides by 2</em>

$CE=\dfrac{1}{\not2_1}\cdot\not2^1\\\\\boxed{CE=1\ ft}$

Which of the following is the equation of a line parallel to the line y = -x + 1,

Lynna [10]

Answer:

Step-by-step explanation:

y = -x + 1.....slope here is -1. A parallel line will have the same slope

y = mx + b

slope(m) = -1

(4,1)....x = 4 and y = 1

now we sub and find b, the y int

1 = -1(4) + b

1 = -4 + b

1 + 4 = b

5 = b

so ur equation is : y = -x + 5.....rearrange = x + y = 5 <==

168 students play at least one sport 35% of students at the school how many students are at the school

mash [69]

X= number of students in school

Total number of students multiplied by % equals portion of students

x * 35%= 168
0.35x= 168
divide both sides by 0.35
x= 480

ANSWER: There are 480 students in the school.

Hope this helps! :)

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 450 gram setting. It

Arturiano [62]

Answer:

Test statistic = -2.25

P-value = 0.0199

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 450 gram

Sample mean, $\bar{x}$ = 441 grams

Sample size, n = 16

Alpha, α = 0.05

Sample variance = 256

$\sigma^2 = 256\\\sigma = \sqrt{256} = 16$

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 450\text{ grams}\\H_A: \mu < 450\text{ grams}$

We use one-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{441 - 450}{\frac{16}{\sqrt{16}} } = -2.25$

Now,

Degree of freedom =

$=n-1 = 16-1=15$

We can calculate the p-value from the table as:

P-value = 0.0199

Conclusion:

Since the p-value is smaller than the significance level we fail to accept the null hypothesis and reject it.

Thus, there is enough evidence to support the claim that the machine is under filling the bags .
