Question: Given that BE bisects ∠CEA, which statements must be true? Select THREE options.

(See attachment below for the figure)

m∠CEA = 90°

m∠CEF = m∠CEA + m∠BEF

m∠CEB = 2(m∠CEA)

∠CEF is a straight angle.

∠AEF is a right angle.

Answer:

m∠CEA = 90°

∠CEF is a straight angle.

∠AEF is a right angle

Step-by-step explanation:

Line AE is perpendicular to line CF, which is a straight line. This creates two right angles, <CEA and <AEF.

Angle on a straight line = 180°. Therefore, m<CEA + m<AEF = m<CEF. Each right angle measures 90°.

Thus, the three statements that must be TRUE are:

m∠CEA = 90°

∠CEF is a straight angle.

∠AEF is a right angle

Given the following information, determine if one of the brands is a better buy. Brand A: 14 ounces for $44. 66 Brand B: 20 ounc
maksim [4K]

Division is one of the basic mathematical operations. The cost of Brand A and B is the same.

<h3>What is division?</h3>

The division is one of the most basic arithmetic operations. It is used to find the number of times a number is been added to itself.

Given to us

Brand A: 14 ounces for $44.66

Brand B: 20 ounces for $63.80

To compare the two brands we will find the cost of one ounce for each brand.

For Brand A,

The cost of 14 ounces is $44.66, therefore,

\text{Cost of one ounce} = \dfrac{\$44.66}{14}\\\\\text{Cost of one ounce} = \$3.19

For Brand B,

The cost of 20 ounces is $63.80, therefore,

\text{Cost of one ounce} = \dfrac{\$63.80}{20}\\\\\text{Cost of one ounce} = \$3.19

From the above two values, we can conclude that the cost of Brand A and B is the same.

IgorC [24]
<h2><u>Answer with explanation</u>:</h2>

Let \mu be the population mean.

As per given , we have

H_0:\mu \leq4\\\\ H_a: \mu >4

Since the alternative hypothesis is right-tailed , so the test is a right-tailed test.

Also, population standard deviation is given \sigma=1 , so we perform one-tailed z-test.

Test statistic : z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

, where \mu = Population mean

\sigma = Population standard deviation

n= sample size

\overline{x} = Sample mean

For n= 18 , \overline{x}=4.50 , \sigma=1 , \mu =4, we have

z=\dfrac{4.5-4}{\dfrac{1}{\sqrt{18}}}\approx2.12

P-value (for right tailed test): P(z>2.12) = 1-P(z≤ 2.12)  [∵ P(Z>z)=1-P(Z≤z)]\

=1- 0.0340=0.9660

Decision : Since P-value(0.9660) > Significance level (0.01), it means we are failed to reject the null hypothesis.

[We reject null hypothesis if p-value is larger than the significance level . ]

Conclusion : We do not have sufficient evidence to show that the goal is not being met at α = .01 .

A van travels from Town A to Town B. It uses 1 gallon of gas for every 24 miles traveled. A) How many gallons of gas does the va
Setler79 [48]

Answer:

A)  \frac{x}{8} gallons

B)  Distance between Town A and Town B is 48y  miles


Step-by-step explanation:

A)

We know, number of gallons = \frac{DistanceTravelled}{MilesPerGallon}

if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:

Number of Gallons = \frac{DistanceTravelled}{MilesPerGallon}=\frac{3x}{24}=\frac{x}{8}


B)

Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>

We use the same formula and solve for distance (let distance between A and B be "D"):

NumberOfGallons=\frac{DistanceTravelled}{MilesPerGallon}\\2y=\frac{D}{24}\\D=2y*24\\D=48y
