Answer:

CNBD

Step-by-step explanation:

From the diagram, we can see that:

$\displaystyle BL\parallel CA$

Then by Alternate Interior Angles:

$\angle LBA\cong \angle CAB\text{ and } \angle BLC\cong \angle ACL$

From vertical angles, we also know that:

$\displaystyle \angle BKL\cong \angle AKC$

This is all we can gather from the given image. Knowing only three pairs of angles cannot prove congruence, as proving congruence requires at least one side.

Congruence cannot be determined.

Answer:

Cannot be determined

Step-by-step explanation:

With BL and AC being parallel, we can deduce that the two triangles in question share all three of their angles. However, there is no information given that implies any of the sides are equal. AAA (Angle-Angle-Angle) is a proof of similarity, but not congruence, therefore the two triangles cannot be determined to be congruent.

odness-of-fit test where all assumptions were met yielded the chi-square test statistic χ2=1.92 and a corresponding p-value of 0

mojhsa [17]

Answer: hello the options related to your question is missing attached below are the options

answer : The researcher did not state that the p-value is conditional on the null hypothesis being true ( A )

Step-by-step explanation:

What is wrong with the researcher's interpretation is that the researcher did not state that the p-value is conditional on the null hypothesis being true.

The P-value is a required value when either rejecting or accepting the null hypothesis. and the researcher did not add the clause that the probability of getting a statistic > 1.92 provided the null hypothesis is assumed to be true

Can somebody help me with more line segment problems?

Nikolay [14]

Now I am not sure what length you're supposed to find for problem 9, but x = 3.3 i think.

10.)

(14+x)+(x+21) = 13

2x+35=13

2x = -22

x = -11

FE = -11 + 14 = 3 units

11.)

10 + 2x - 10 = 3x - 8

2x = 3x - 8

-x = -8

x = 8

10 + 2(8) -10 = 16 units

Two different types of tea are sold in your store. If you know 100 cups of tea were sold and one type sold 5 times as much as th

LiRa [457]

The answer can not be found from the given information

Step-by-step explanation:

Two different types of tea are sold in your store

You know 100 cups of tea were sold
One type sold 5 times as much as the other type

We need to find how much of each type of tea were sold

Assume that the two types are x and y

∵ x represents one type of tea

∵ y represents the other type of tea

∵ 100 cups of tea where sold

- Add x and y, then equate the sum by 100

∴ x + y = 100 ⇒ (1)

∵ x type is 5 times as much as y type

∴ x = 5y ⇒ (2)

Now we have a system of equations to solve it

Substitute x in equation (1) by equation (2)

∴ 5y + y = 100

∴ 6y = 100

- Divide both sides by 6

∴ y = 16.67

<em>But you know number cups must be whole numbers</em>

The number cups can be 102 <em>OR</em> one type is 4 times as much as the other type

If the number of cups is 102, then

85 cups of one type and 17 cups of the other type were sold

If one type is 4 times as much as the other type, then

80 cups of one type and 20 cups of the other type were sold

The answer can not be found from the given information

Sally begins hiking at an elevation of 224 ft then she descends 131 ft and climbs 67 feet higher than her current position she t

Temka [501]

Answer:

Sally ends at 3 feet below zero point.

Step-by-step explanation:

Let be $h$ the height with respect to zero point, which is represented by the following sum:

$h = \Sigma_{i=1}^{n} h_{i}$

Where:

$h_{i}$ - i-th travelled height, measured in feet.

In addition, positive sign means ascension, whereas negative sign means descent.

The statement can be translated into the following mathematical identity:

$h = h_{1}+h_{2}+h_{3}+h_{4}$

$h = 224\,ft+(-131\,ft)+67\,ft -163\,ft$

$h = -3\,ft$

Sally ends at 3 feet below zero point.
