If so, what property?
Answer:
Yes, by ASA congruence.
Step-by-step explanation:
Solving :
∠DAB = ∠BCD (indicated in diagram)∠ADB = ∠DBC (indicated in diagram)BD = BD (common side)ΔABD ≅ ΔCDBHence, as 2 angles and a side of the triangles are equal, we can say they are congruent by ASA congruence.

A study of the impact of caffeine consumption on reaction time used 24 subjects and divided them into 12 pairs based on the average hours of sleep they got. One randomly assigned member of each pair drank two cups of caffeinated coffee, and the other drank two cups of decaf. Each subject's performance on a standard reaction time test was recorded. The difference for each pair is calculated (caffeinated - decaf). A 95% confidence interval for the mean difference in reaction times is (-1.2, 0.75).
What is a valid conclusion they can make?
a. Because the confidence interval includes more negative numbers than positive, we have convincing evidence that caffeine decreases reaction time.
b. Because the confidence interval includes 0, we don't have convincing evidence that there is a difference in reaction time.
c. Because the center of the interval is -0.225, we have convincing evidence that decreases reaction time.
d. Because the confidence interval includes 0, we have convincing evidence that the true mean difference is 0.
Using the confidence interval, it is found that the correct option regarding the valid conclusion they can make is given by:
b. Because the confidence interval includes 0, we don't have convincing evidence that there is a difference in reaction time.
What are the hypothesis tested?At the null hypothesis, it is tested if there is not a difference in reaction times, that is:
[tex]H_c - H_d = 0[/tex]
At the alternative hypothesis, it is tested if there is a difference, that is:
[tex]H_c - H_d \neq 0[/tex]
The interval contains 0, hence there is not enough evidence to reject the null hypothesis, which means that option B is correct.

Answer:
Step-by-step explanation:
The total cost of Tandoori Seasoning is incorrect.
Vijay made an error when multiplying 3.5 ounces by $3.60 .
Cost of both spice blends is actually $23.6.
What is a error?
it is defined as the deviation of an entitiy from its corrected value while calculating.
Now it is given that,
Tandoori Seasoning = 3.5 ounces for $3.60 an ounce
Garam Masala = 4 ounces for $2.75 an ounce
Hence, total cost of Tandoori Seasoning = 3.5*$3.60
⇒ total cost of Tandoori Seasoning = $12.6
and total cost of Garam Masala = 4*$2.75
⇒ total cost of Garam Masala = $11
Therefore, total cost for the spices =cost of Tandoori Seasoning + cost of Garam Masala
⇒ total cost for the spices = $12.6 + $11
⇒ total cost for the spices = $23.6
Hence, we conclude that,
The total cost of Tandoori Seasoning is incorrect.
Vijay made an error when multiplying 3.5 ounces by $3.60 .
Cost of both spice blends is actually $23.6.

The statement about the graphs is true is: Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.

Determine the equation of the line passing through the points (-1, 1) and (1, 7).
Write the line in standard form Ax+By=C
Answer:
[tex]3x + y = -4[/tex]
Step-by-step explanation:
We were given to points on the line we are trying to find, hence we are able to determine the slope/gradient.
[tex]( - 1, \: 1) \: and \: (1, \: 7) \\ slope = \frac{ {y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} } \\ \\ s = \frac{7 - 1}{1 - ( - 1)} \\ s = \frac{6}{2} [/tex]
Slope is equal to 3.
Since we have the value for the slope, we can now use one of the points on the line to determine the equation of the line.
note that the coefficient of x is the slope. In this case the A from the standard form (Ax + By= C) is the slope.

The volume of a right cone is 3000π units^3. If its radius measures 15 units, find its height.
Answer:
40 unitsStep-by-step explanation:
In the question, it is given that a right cone has a radius of 15 units and volume of 3000π units³ and we have to find the height of the cone.
[tex] \: [/tex]
To Find the height of the cone, we must know this formula :
[tex]\\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { \dfrac{1}{3} \: \pi {r}^{2}h ={ Volume_{(cone) }}}}}}}}} \\ \\[/tex]
Where,
r refers to the radius of the cone. h refers to the height of the cone.Now, we will substitute the values in the formula :
[tex] \\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{1}{3} \times \pi \times {(15)}^{2} \times h = 3000 \pi}}}}}}} \\ \\[/tex]
Cancelling π from both sides we get :
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{1}{3} \times \cancel\pi \times {(15)}^{2} \times h = 3000 \cancel\pi}}}}}}} \\ \\[/tex]
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{1}{3} \times 225 \times h = 3000}}}}}}} \\ \\[/tex]
[tex]\\ {\longrightarrow{ \qquad{{ {\pmb{\sf { \dfrac{225}{3} \times h = 3000}}}}}}} \\ \\[/tex]
[tex] \\ {\longrightarrow{ \qquad{{ {\pmb{\sf 75 \times h = 3000}}}}}} \\ \\[/tex]

Option B is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.

Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
Tangent is defined as the ratio of the opposite side to the adjacent side of a right triangle.
It is positive when the opposite side and the adjacent side are both positive or both negative.
In the first quadrant (I), both the opposite and adjacent sides are positive, so the tangent is positive.
In the second quadrant (II), the opposite side is positive and the adjacent side is negative, so the tangent is negative.
In the third quadrant (III), both the opposite and adjacent sides are negative, so the tangent is positive.
In the fourth quadrant (IV), the opposite side is negative and the adjacent side is positive, so the tangent is negative.
Therefore,
The quadrants in which the tangent is positive are I and III.

Step-by-step explanation:

The level of allergic symptoms in both groups cannot be compared to determine if the medication had a significant effect because one group only received a placebo accurately describes the benefit of comparison in the experiment shown in the design web. Thus option A is correct.
What is an experiment?A scientific experiment inside which you carry out a sequence of tasks and closely monitor their results to discover new information. An investigation is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that hasn't been tried before.
Although one sample only obtained a placebo inside the investigation depicted in the design web, it is difficult to compare the severity of allergic rhinitis in both groups to establish whether the drug had a substantial impact.
